A Woman Who Is A Carrier For #1 Hemophilia And A Man That Does Not Have Thecondition Have Children. What

Answers

Answer 1

Answer:

Explanation:

A woman who is a carrier for #1 hemophilia and a man that does not have the condition have children. What is the probability that they will have a child with the condition being studied? What is the gender of that child?

if the baby gets the Y chromosome from the father it will be a boy. If the boy gets his mother's X chromosome with the hemophilia gene he will have hemophilia. If he inherits his mother's other X chromosome, he will have normal blood clotting. If the baby gets the X chromosome from the father it will be a girl.

#4 A woman that is heterozygous for type A blood and a man that is heterozygous for type B blood have children. What are the possible blood types of their children?

One parent with A and another with B can produce a child with A, B, AB or O blood types.

#5 Two people are both unknowingly carriers for the cystic fibrosis gene. What is the probability that they will have children with cystic fibrosis?

If both parents are carriers there is a 1 in 4 (25 percent) chance that both will pass on the non-functioning gene, which would result in a pregnancy affected with cystic fibrosis.

#3 A woman that is heterozygous for Huntington's disease and a man that does not have the condition have children . What is the probability that their children inherit the Huntington's gene ?

Huntington's disease (HD) is what is called a dominant genetic disease. What this usually means is that a child only has a chance of getting a disease like this if a parent has it too. But parents without HD can have a child with HD. This is true of any dominant genetic disease

In an experiment to determine the acceleration due to gravity, one student holds a pencil at arm’s length and drops it. Another student starts a timer when the first student lets go and stops the timer when the pencil hits the ground. They repeat this several times and take an average. Is this a valid experiment, why or why not?

Answers

Answer:

The correct answer is - No, it is not valid because the short distance means there will be a lot of error due to the student's reaction time.

Explanation:

In this experiment to determine the acceleration due to gravity, there may be errors because of the student’s reaction time. The reaction can be late or early than prior reactions.

The other error can be caused by the distance was only at arm’s length throughout the experiment, which means that there was no independent variable that is the difference or change in the distance. This also makes the experiment invalid.

B.Identification and binding of RNAP on to the promoter sequence

C.Conversion of open initiation complex to closed initiation complex

D.Synthesis of RNA after the formation of open initiation complex

Answers

Answer:

The correct answer is - B. Identification and binding of RNAP onto the promoter sequence.

Explanation:

Bacterial RNA polymerases have subunits known as Sigma factors responsible for the identification and specificity of promoter binding of RNAP and regulate the efficiency of RNA synthesis during transcription is initiated.

These bacteria producing the nonfunctional subunits of RNA polymerase or sigma factor will be unable to identify and tightly bind to promoter elements that are RNAP.


Name one component of the digestive system that performs mechanical digestion and describe how
it contributes to acquiring nutrients from food.

Answers

Answer:

The stomach and the teeth both perform mechanical digestion, which is physically (as opposed to chemically) breaking the food into smaller components. This exposes a larger surface area for chemical digestion and release of nutrients. The teeth are vital to mastication, which breaks large bites of food down into smaller pieces that are easily swallowed. The stomach’s muscle contractions churn the food to expose all particles to the acid and digestive enzymes..

Explanation:

The locus B on the X chromosome of a malaria-carrying mosquito shows a 49% recombination rate with respect to the locus M. Since a recombination rate of 50% is essentially indistinguishable from independent assortment, you might be tempted to look for a locus that falls between B and M. Before you decide to do all that work, you run a chi square test to determine the P value of your experiment.

Required:
What range of P values would tell you that you should accept the conclusion that locus B and locus M are, indeed, 49mu apart and that another locus is not necessary?

Answers

Answer:

The correct answer is - P = 0.45

Explanation:

The Chi-square test is a test that determines the assorted genes independently. Here p-values used to make conclusions in significance testing.

If the p value is less than the significance level we expect or choose, then this null hypothesis is rejected in favor of the alternative hypothesis. It p value is greater than or equal to the significance level, then we fail to reject the null hypothesis.

So in this case, as the recombination rate is 49% so the p value which satisfies the conclusion will be around 0.45 and values near to it.

help me in my hw landslide can be prevented by terrace farming why​

Answers

Answer:

Reducing the intensity of runoff.

Explanation:

Terrace farming prevent landslides and erosion to occur by reducing the intensity of runoff. This farming also reduce the risk of drought due to raising the moisture content in the soil and allowing water to slowly infiltrate into the soil. Due to terrace farming, the runoff water moves very slowly which causes less erosion of the soil as well as reduces the intensity of water flow which causes more infiltration.

Due to lack of expansion of lungs.

Explanation:

The lack of surfactant compound would result in respiratory distress because Surfactant enables the lungs to expand more easily which allows easiness in respiration. Without surfactant, the air sacs in the lungs will collapse very easily. This collapse leads to decreased amounts of air or oxygen in the lungs which makes it very difficult for the people or infant to breathe.

You are studying an enzyme that is inactivated by phosphorylation and create a mutant in which the threonine that is normally phosphorylated is replaced with glutamate. Predict the impact of this change on the activity of this enzyme. Group of answer choices

Answers

Answer:

always active  

Explanation:

Phosphorylation is a posttranslational modification that consists of the addition of phosphate groups to specific amino acids on the protein. Phosphorylation acts as a molecular switch for proteins that are phosphorylated (i.e., in some situations phosphorylation acts to activate protein function, whereas in other situations phosphorylation can inactivate protein function). Phosphorylation modifies the three-dimensional structure of the protein, thereby affecting, for example, the accessibility of the active site of a phosphorylated enzyme to its substrate. Phosphorylation can occur only at the side chains of three amino acids: Serine, Threonine and Tyrosine. In this case, the enzyme is inactivated by phosphorylation on the Threonine residue, so it is expected that the mutant enzyme cannot be phosphorylated, remaining in an active state.

Hypoxia is known to cause a disruption of somitogenesis. If a mouse embryo were temporarily exposed to low levels of oxygen during the final stages of somitogenesis, what would you expect to see in the vertebral column of the newborn mouse

Answers

In mammals, hypoxia may cause defects during fetal development. In this case, it would be expected to observe an abnormal development of the caudal (tail) vertebrae

Somitogenesis refers to the process during embryo development in which somites form. These somites are cells that will give rise to structures associated with the vertebrae body plan. Somites form sequentially from the head to the tail, where each new somite forms on the caudal or tail region of the previous one.

Somitogenesis represents the first sign of segmentation of the developing vertebrate embryo. During somitogenesis, the unsegmented paraxial or presomitic mesoderm in the trilaminar embryonic stage is segmented in order to form pairs of somites. Moreover, caudal vertebrae refer to the bones that form the tail of vertebrates, which derive from caudal somites.

Embryo hypoxia refers to the condition in which the developing embryo does not receive sufficient oxygen (O2) supply. It has been shown that hypoxia during embryo development can increase the incidence of malformations. In this case, embryo hypoxia affects normal caudal somite segmentation, thereby leading to defects in the caudal (tail) vertebrae.

why does a rational producer reject the business in increasing stage​

Answers

Answer:

In three stages of production to which are hold by the law of diminishing marginal returns the second stage is considered to as the rational stage of production as compared to the first and third stage this is due to the fact that this stage it comes out with the best assumptions for efficient and sustainable production, thereby the stage it simultaneously shows the positivity of the average products and marginal product hence, in the increase of labour the total production or outputs increased likewise with the same quantity of fixed factor, therefore this stage it gives direction to the producer on how the higher units of output can be produced.

Unlike the first stage to which it shows each additional variable could enhance more production and such this it signifies an increasing of marginal return but for this case it do not give out the direction in permanent production since labours are needed fewer and in the decrease in number of labour can brings about underproduction.

Also the third stage marginal return is frankly negative because in adding more variable inputs will further led into adding more number of labour hence the increase of labour will contributes to under production as it may be due to labour capacity and efficiency concern.

Muscle skeleton — the specialized tissue that connects to the bones and enables movement. The musculoskeletal system is called skeleton muscles and bones together (also known as the locomotor system). Generally speaking, the biceps and triceps of the front or the back of the upper arm are arranged into opposing pairs. Skeletal muscles are controlled by humans, and so are also called voluntary muscles. Another term is streaked muscles, as the tissue looks streaked on a microscope. smooth muscle -located throughout several internal tissues such as the digestive tract, the uterus, and blood vessels such as the artery. The smooth muscle in layered sheets is placed along the construction length in waves. Another typical word is an involuntary muscle, because, without our knowledge, the motion of the smooth muscle takes place.The cardiac muscle - the heart muscle. Without our conscious awareness the heart contracts and relaxes.

Some death-inhibiting members of the Bcl2 family inhibit apoptosis by blocking cytochrome c release from mitochondria. D. The death-promoting members of the Bcl2 family include Bcl2 itself.

Answers

Answer: The statement that is FALSE is D (The death-promoting members of the Bcl2 family include Bcl2 itself.)

Explanation:

Apoptosis is a process found in multicellular organisms whereby cells follows a order of events which eventually leads to their death without releasing harmful substances into the surrounding area of the cells. Through this process, old cells, unnecessary cells, and unhealthy cells are eliminated from the body.

The process of apoptosis can be regulated by cell regulator proteins such as Bcl-2 family.

Bcl-2 stands for B-cell lymphoma 2 which are encoded in human cells by BCL2 gene. The Bcl-2 family are capable of regulating apoptosis by either inducing it or inhibiting it.

Bcl-2 and Bcl-XL, PREVENT apoptosis by preventing the release of mitochondrial apoptogenic factors such as cytochrome c and AIF (apoptosis-inducing factor) into the cytoplasm

Part of the Bcl-2 family is the Bax and Bak and they are the core regulators of the intrinsic pathway of apoptosis. They PROMOTE apoptosis by inducing the release of cytochrome c from mitochondria into the cytosol. Therefore, the death-promoting members of the Bcl2 family does not include Bcl2 itself.

The CRISPR-Cas9 genome editing system can be used to edit genes and correct mutations associated with inherited diseases. However, this technology also has the potential to edit genes in germline cells in order to irreversibly modify the human species and the natural evolution of life

Explanation:

The CRISPR-Cas9 (Clustered regularly interspaced short palindromic repeats and CRISPR-associated protein 9) system is a natural prokaryotic defense system used by bacteria to defend against invading DNA. In the laboratory, the CRISPR-Cas9 system has been repurposed to create a versatile genome-editing tool that allows us to modify the genome of mammalian cells in a targeted fashion. The CRISPR-Cas9 is a simple gene-editing tool that consists of a single guide RNA (sgRNA) that guides the Cas9 enzyme to the exact genomic location where Cas9 needs to make a cut, which is then repaired by different DNA repair mechanisms. During DNA repair, nucleotides can be replaced and/or deleted, thereby producing desired genomic modifications. The CRISPR-Cas9 has an enormous potential to repair mutations in genes associated with inherited genetic disorders and cancer (i.e., oncogenes might be reversed in vivo by using this technology). However, the CRISPR-Cas9 genome editing system is also a subject of concern due to its dual use. For example, this technology can be used to modify the genome of germline cells by inducing mutations that can be passed across generations, thereby irreversibly modifying human DNA and altering the normal course of evolution.
