What are the chances of a child with a long nose? out of or % c. What are the chances of a child with a stubby nose? out of st or__% d. Would their children be considered purebred like Dobby? Explain:​

Answers

Answer 1

Assuming a single diallelic gene coding for the trait and expressing complete dominance, the phenotypes, genotypes, and probabilities of getting each of them vary according to the parentals' genotypes. See the options below.

---------------------------------

Since I do not have the genotypes from #2, I will provide different potential scenarios for this question.

I advise you to check on them and see which one matches the genotype from #2.

Let us assume a single diallelic gene is coding for the trait and expresses complete dominance.

SCENARIO 1  ⇒ long nose is the dominant trait

Let us say that

L is the dominant allele and codes for long nosel is the recessive allele and codes for stubby nose

Since long nose is dominant over stubby nose

LL and Ll ⇒ long nosell ⇒ stubby nose

If Dobby comes from a purebred family and has long nose, his genotype must be LL.

And if Viola has stubbi nose, her genotype must be ll.

Cross 1

Parentals)    LL   x    ll

Gametes)  L    L     l    l

Punnett square)    L       L

                      l      Ll      Ll

                      l      Ll      Ll

F1) Genotype ⇒ 100% heter0zyg0us Ll

     Phenotype ⇒ 100% long-nosed

There is 100% chances for a child to have a long noseThere is 0% chances for a child to have a stubby noseThese children are not purebred

                                             **********

SCENARIO 2  ⇒ Stubby nose is the dominant trait

Let us say that

S is the dominant allele and codes for stubby noses is the recessive allele and codes for long nose

Since stubby nose is dominant over long nose

SS and Ss ⇒ stubby nosess ⇒ long nose

If Dobby comes from a purebred family and has long nose, his genotype must be ss.

And if Viola has stubbi nose, her genotype must be either SS or Ss.

There are two possible crosses.

Cross 1 : Violet is h0m0zyg0us dominant SS

Parentals)    SS   x    ss

Gametes)  S    S     s    s

Punnett square)   S       S

                      s     Ss     Ss

                      s     Ss     Ss

F1) Genotype ⇒ 100% heter0zyg0us Ss

     Phenotype ⇒ 100% stubby-nosed

There is 100% chances for a child to have a stubby noseThere is 0% chances for a child to have a long noseThese children are not purebred

Cross 2: Violet is heter0zyg0us, Ss

Parentals)    Ss   x    ss

Gametes)  S    s     s    s

Punnett square)   S       s

                      s     Ss     ss

                      s     Ss     ss

F1) Genotype ⇒ 50% heter0zyg0us Ss and 50% h0m0zyg0us recessive ss

     Phenotype ⇒ 50% stubby-nosed and 50% long-nosed

There is 50% chances for a child to have a stubby noseThere is 50% chances for a child to have a long noseThese children are not purebred

Both gymnosperms and angiosperms are heterosporus. In gymnosperms, the pollen and the megaspores are produced in separate _______. In angiosperms, the pollen and the megaspores are produced in separate structures, but within the same ______.

Answers

Answer:

Places and location.

Explanation:

In gymnosperms, the pollen and the megaspores are produced in separate places. Megaspores made in cones that develop into the female gametophytes that is present inside the ovules of gymnosperms, while pollen grains develop from cones that produce microspores. while on the other hand, In angiosperms, the pollen and the megaspores are produced in separate structures, but within the same place i.e. flower which has both male and female reproductive organs.

The words that should be filled in the blanks are places and location respectively.

What do you mean by Megaspores?

Megaspores may be defined as a spore in heterosporous plants giving rise to female gametophytes and usually larger than a microspore.

Gymnosperm produces both male and female cones. Both make the gametes needed for fertilization, which makes gymnosperm heterosporous.  In angiosperms, cones are not found, pollen is produced by the anthers of the stamens in flowers.

Therefore, the words that should be filled in the blanks are places and location respectively.

During transcription, RNA polymerase synthesizes RNA from a DNA template with the help of accessory proteins.

a. True
b. False

Answers

Answer:

The correct answer is a. True

Explanation:

The information to produce a protein is coded in the cells in deoxyribonucleic acid (DNA). Transcription is the process in which a DNA sequence is copied into a ribonucleic acid (RNA) sequence. This RNA sequence is a messenger RNA (mRNA) because it will be then translated into a functional protein. For this, the DNA sequence is read and an RNA strand is synthesized by an RNA polymerase (an enzyme that synthesizes RNA molecules from a DNA template). During the process participate other proteins, such as DNA binding proteins, activators, coactivators, etc. (accessory proteins).

Regarding the models of cooperativity:_______.
a. the concerted model is based on the

c. T state is low affinity and R state is high affinity.
d. the concerted model and the sequential model are mutually exclusive.
e. these models, strictly speaking, only apply to tetramers.

Answers

Answer:

c. T state is low affinity and R state is high affinity.

Explanation:

Hemoglobin (Hb) is a multimeric protein molecule that transports oxygen from the lungs to the body's tissues in red blood cells. Hb exists in two quaternary states: 1- a T-state or deoxygenated conformation, which is referred to as 'deoxyhemoglobin'; and 2-a R state or fully oxygenated conformation, which is referred to as 'oxyhemoglobin'. The sequential model of cooperativity states that the conformation of a multimeric protein changes with each binding of a ligand, thereby sequentially changing its affinity for the ligand (i.e., cooperativity is dependent on ligand-induced). In consequence, this model states that the conformational state and affinity of Hb monomers change as they bind to oxygen.

The process by which dissolved gases are exchanged between the blood and interstitial fluids is Select one: a. cellular respiration. b. diffusion. c. external respiration. d. breathing. e. pulmonary ventilation.

Answers

Answer:

b. diffusion.

Explanation:

Diffusion can be defined as the movement of gas molecules from a region of high concentration to a region of lower concentration until an equilibrium is attained or reached. This mixing of gas molecules in the liquid or gaseous state is due to their kinetic energy of random motion i.e without requiring bulk motion.

This ultimately implies that, diffusion is a phenomenon through which gas molecules in either a gaseous or liquid state spread out in response to a concentration gradient, which is simply the difference in concentration of the gases across a space.

During diffusion, molecules move from areas of high concentration to areas of low concentration.

In this context, the process by which dissolved gases are exchanged between the blood and interstitial fluids is referred to as diffusion.

On a related note, this process is also referred to as internal respiration because it involves the exchange of oxygen gas and carbon (II) oxide gas between tissue cell and capillaries.

Given the range of current speeds shown on the graph above, would deposition ever be possible for clay (0.001 mm) or silt (0.01mm) particles?
Answer yes or no and explain your answer.

Answers

Answer:

Yes.

Explanation:

Yes, deposition can be possible for clay (0.001 mm) and silt (0.01mm) particles when the agent that carry its load is absent in that region such as wind. Wind is the agent that moves clay and silt particles with it so if there is high wind in a specific region, no deposition will occur while on the other hand, those areas where wind is not present, deposition will definitely occurs so we can say that deposition depends on the presence and absence of wind.

Suppose a researcher introduces a mutation into the glucosidase domain of the mammalian glycogen debranching enzyme. The mutation inhibits the activity of the glucosidase but does not affect the other functions of the enzyme. The researcher then introduces the mutated enzyme into mammalian cells that do not express wild type glycogen debranching enzyme. Predict the effect of the mutation on glycogen metabolism.

Answers

Answer:

cells will have glycogen molecules with branches of a single glucose residue

Explanation:

Glycogen debranching enzymes are proteins that catalyze the removal of branching from glycogen, which is a multibranched polysaccharide composed of glucose units and serves as a form of energy storage. These enzymes have two catalytic activities on a single polypeptide chain: glucosyltransferase and glucosidase activities, which are both required for glycogen breakdown. Glycogen degradation requires both glycogen phosphorylase and glycogen debranching enzymes. First, a glycogen phosphorylase acts to digest a glycogen branch down to four glucose residues. Subsequently, the debranching enzyme through its glucosyltransferase activity acts to transfer three glucose residues to a nearby branch of the glycogen chain. Finally, through its glucosidase activity, the debranching enzyme cleaves the remaining α-1,6 linkage in order to release free glucose.

Why does population growth slow as size increases in the logistic model?

Explanation:

Population growth slow as size increases in the logistic model A : due to density-dependent factors is correct option.

In the logistic model of population growth, the slowdown in population growth as the population size increases is primarily attributed to density-dependent factors. Density-dependent factors are those that have a stronger impact on a population when its density (number of individuals per unit area) is higher. As a population grows and becomes more dense, competition for resources (such as food, space, and mates) intensifies, and factors like disease transmission and predation become more significant.

These density-dependent factors can lead to a decrease in birth rates, an increase in death rates, or both, which ultimately results in the population growth rate slowing down and eventually stabilizing at its carrying capacity (the maximum sustainable population size for a given environment). This pattern is characteristic of the logistic growth model, which describes a more realistic and sustainable form of population growth compared to the exponential growth model.

Indicate whether each statement is true or false: 1. Compliance is the tendency for blood vessel volume to increase as blood pressure decreases. True 2. Blood vessels with a large compliance exhibit a small increase in volume when the pressure increases a small amount. True 3. Venous compliance is approximately 24X greater than arterial compliance, so as venous pressure increases the volume of veins greatly increases. True

Answers

Answer:

1. False

2. False

3. True

Explanation:

1. Compliance is the capacity of a container to increase in size to allow it hold more content. Blood vessel, arteries and veins expand (increase in volume) to be able to accommodate a surge in blood flow, which is as a result of an increase in pressure of the blood from the heart pumping of the blood

Therefore, compliance in the tendency for blood vessel volume to increase as the blood pressure increases not decrease

The statement is false

2. A large compliance is indicative of being highly sensitive to changes in pressure

Compliance, C = ΔV/ΔP

From the above equation, a blood vessel with a large compliance, exhibit a large increase in volume when the increase in pressure is small

Therefore, the statement 'Blood vessels with a large compliance exhibit a small increase in volume when pressure increases a small amount; is false

3. The compliance of the vein ranges from 10 to 20 times (30 times in some literature) greater than arteries. A factor which can be affected by the vascular smooth muscle contraction or relaxation

Therefore, the statement, 'venous compliance is approximately 24 times larger than arterial compliance, so as venous pressure increases the volume of veins greatly increases' is true
