Answers

Answer 1
Hannah that is what I would answer....
Answer 2

According to the question, Hannah would have denser bones because her bone would get heavier due to water absorption through epithelial cells.

What is Bone density?

Bone density may be characterized as a type of measurement that significantly involves the accumulation certain amount of minerals contained in a certain volume of bone. This measurement is generally used to find out and treat serious bone loss, called osteoporosis.

When an individual is practicing in a swimming pool constantly for a longer period of time, it is observed that his/her bone density must be increased as compared to those who are running or performing other types of athletic activities.

Therefore, according to the question, Hannah would have denser bones because her bone would get heavier due to water absorption through epithelial cells.

Moles are mammals that live underground and eat worms. The moles are adapted to use their sense of smell to locate their food. Which environmental change would MOST LIKELY allow for an increase in the number of moles born with a better sense of smell?

A.
More rainfall makes the soil harder for digging so the moles need to have a better sense of smell to locate the worms.

B.
Less rainfall causes the worms to come closer to the surface so the moles need to have a better sense of smell to locate the worms.

C.
More rainfall makes the soil easier for digging so the moles need to have a better sense of smell to locate the worms.

D.
Less rainfall causes the worms to burrow further underground so the moles need to have a better sense of smell to locate the worms.

Answers

Answer:

I think the answer is D

Explanation:

Because if there is less rainfall that will make it harder for the moles to look for the  worms and to sense the worms so they will have to have sense harder or dig harder to get the worms. hope this helps!

Less rainfall causes the worms to come closer to the surface so the moles need to have a better sense of smell to locate the worms.

What are adaptations of moles?

Moles are adapted to use their sense of smell to locate their food, which is mainly worms. In dry conditions, worms tend to come closer to the surface in search of moisture and as a result, moles would need to have a better sense of smell to locate the worms.

In this scenario, the moles with better sense of smell would be more successful in finding food and would be more likely to survive and reproduce, passing on their advantageous traits to the next generation. This would lead to an increase in the number of moles born with a better sense of smell.

Why do mapping experiments become less accurate when the distances between genes become large? View Available Hint(s) Why do mapping experiments become less accurate when the distances between genes become large? Interference is greater when the distance between genes is large. Multiple crossovers are more common. Crossover gametes become less common. Recombination occurs less frequently in long chromosomes.

Answers

Answer:

Multiple crossovers are more common.

Explanation:

Genome editing can be defined as a high-tech process which avail scientists the opportunity or ability to remove (delete), replace and insert Deoxyribonucleic Acid (DNA) sequence in a living organism such as bacterias, animals, plants etc in order to correct a genetic disorder and to improve on their physical and chemical conditions.

A mapping experiment refers to an investigation which typically involves the process of manipulating an independent variable (the cause) in order to be able to determine or measure the dependent variable (the effect).

This ultimately implies that, an experiment can be used by scientists to show or demonstrate how a condition causes or gives rise to another i.e cause and effect, influence, behavior, etc in a sample.

In mapping experiments, if the genetic distance increases, there would be a consequential increase in multiple crossovers causing a recombinant with an odd number of crossovers and a parental combination with an even number of crossover events by switching it back.

Hence, mapping experiments become less accurate when the distances between genes become large because multiple crossovers are more common.

should have white flowers?
. 100%
75%
50%
25%

Answers

Answer:

50%

Explanation:

If you use a punnet square with Rr x rr you will get 50% white

50% of the offspring should have white flowers when we cross a hybrid genotype for red flowers with pure recessive for white flowers shown in the Punnett square. So, the correct option is C.

What is Punnett square?

Punnett square is defined as the diagram that represents the possible genotypes of the offspring developed after a reproductive event. It was first developed by geneticist Reginald Punnett where the possible genotypes of the offspring are represented in a tabular form with each box in the table representing an event of fertilization.

For above given example,

Rr genotype represents the red flowers.

rr genotype represents the white flowers.

The Punnett square will be:

             R              r

r          Rr              rr

r          Rr              rr

So, 50% have red flowers while 50% have white flowers.

What causes there to be a H+ ion concentration gradient to build up inside the thylakoid space? Check all that apply.
a.) The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space.

b.) A special enzyme produces more H+ ions.

c.) Photons of light create more H+ ions.

d.) The photolysis of water releases H+ ions into the thylakoid space.

Answers

Answer:

a.) The electrons provide energy for the H+ pump to transport more H+ ions into the thylakoid space.

d.) The photolysis of water releases H+ ions into the thylakoid space.

Explanation:

The thylakoid, which is found in the chloroplast, is the site of the first stage of photosynthesis (LIGHT DEPENDENT STAGE) in the cells of plants. The light stage of photosynthesis functions to produce energy (ATP) and NADPH for the second stage called Calvin cycle.

However, this ATP is generated by the power realized from the pumping of Hydrogen ions (H+) into the thylakoid lumen. The following causes the build up of H+ ions in the thylakoid space:

- Light photon hits the chlorophyll molecule, which is the photosynthetic pigment, to become charged. The electrons (e-) generated from this provide energy for the H+ pump to transport more H+ ions into the thylakoid space.

- Photolysis of water, which involves the splitting of water to produce hydrogen ions (H+) causes a build up of H+ in the thylakoid space.

AB positive and O negative are considered as universal blood types. AB+ has no antibodies that can attack the antigens on the red blood cells of the other blood types. The correct option is A.

What is universal receiver?

The people with AB+ blood group are called as the universal receivers. They can safely receive a blood transfusion using any other blood type. Having a universal blood type can save a life of yours or someone else in an emergency.

If you have an AB+ blood type, you have both A and B antigens. Since a person has all of the antigens that are possible, this blood type is the rarest. The AB+ blood type has a positive Rh factor, the recipient will not reject the blood. So it can get any type of blood.

AB type blood has no antibodies against type A or type B blood. So a person with AB blood can receive any type of blood.

Thus the correct option is A.

Synthetic biologists at the Scripps Institute expanded the genetic repertoire by adding two new bases into living bacterial cells. The two bases are named d5SICS and dNaM, and they base-pair with one another. How many different codons are possible in nucleic acids containing six different nucleotides if a codon consists of a consecutive sequence of three nucleotides

Answers

Answer:

216 codons

Explanation:

In the RNA molecule there are four types of nucleotide bases, i.e., Adenine, Uracil (Thymine in DNA), Guanine, and Cytosine. In consequence, the number of possible codons or combinations of nucleotide triplets is 64 (4³ = 64 codons). However, these 64 codons code for only 20 different amino acids because multiple codons can code for the same amino acid, it is for that reason that the genetic code is redundant. In this case, if the number of bases would be six (6) instead of four (4) bases, then the number of possible combinations of nucleotide triplets would be 216 codons (6³ = 216).

Any difference between individuals of the same species is called _______


variation

mutation

Answers

Answer:

SORRY FOR WASTING YOUR TIME THIS IS FOR POINTS ONLY!

Explanation:

<3 also the answer is variation im pretty sure

Any difference between individuals of the same species is called Variation.

Any difference between individuals of the same species is called variation. Variation can manifest in various ways, including differences in physical traits, genetic makeup, behavior, and physiological characteristics. It is a fundamental aspect of biological diversity and plays a crucial role in evolutionary processes.

Variation arises through various mechanisms, including genetic mutations, genetic recombination during sexual reproduction, and environmental influences. Genetic mutations can introduce new genetic variations into a population, while genetic recombination through sexual reproduction can shuffle existing genetic variations. Environmental factors, such as diet, climate, and exposure to different conditions, can also contribute to phenotypic variation.

Variation is essential for populations to adapt and evolve in response to changing environments. It provides the raw material for natural selection, a process by which certain variations are favored or selected for in a population, leading to evolutionary changes over time. Variation allows individuals to possess different traits and characteristics, some of which may confer advantages in specific environmental conditions, while others may be disadvantageous.

Understanding and studying variation is crucial in fields such as genetics, evolutionary biology, and ecology. It helps scientists understand the mechanisms driving genetic diversity, the processes of speciation and adaptation, and the dynamics of populations and ecosystems. Variation also has practical applications in fields such as agriculture, medicine, and conservation, where knowledge of genetic and phenotypic variation can inform breeding programs, medical treatments, and conservation strategies.
