The relatively large number of new mutations that occur in the human genome in each generation is tolerable because: ______________
a. humans have excellent protein repair mechanisms.
b. compared to other organisms, changes in human proteins have relatively small effects on their cells' structures and functions.
c. humans have excellent DNA repair mechanisms.
d. most of the human genome is noncoding DNA, so few mutations affect human proteins.
e. most of the mutations occur in somatic cells, not germ cells.
Answer:
The believe the correct answer is option E.
The relatively large number of new mutations that occur in the human genome in each generation is tolerable because: most of the human genome is noncoding DNA, so few mutations affect human proteins. Therefore, the correct option is D.
What is a human genome?A human genome refers to the complete set of sequences of the nucleic acids that are present in the humans. The human genome contains a relatively large amount of noncoding DNA, which does not code for proteins and is therefore less subject to selective pressures.
Option A, humans have excellent protein repair mechanisms, and Option C, humans have excellent DNA repair mechanisms, are partially true, but do not fully account for the tolerability of new mutations in the human genome.
Option B and E are also not true, as changes in human proteins have relatively small effects on their cells' structures and functions, is not entirely true. Therefore, the correct option is D.

Available data:Single diallelic gene codes for hair in Guinea pigsAllele H is dominant and codes for having hairAllele h is recessive and codes for not having hair
For this gene we will assume complete dominance, meaning that the dominant alele completely hides the expression of the recessive allele.
According to this information, we can say that
Genotype Phenotype
HH Hairy pig
Hh Hairy pig
hh Hairless pig
9) Geneviene does not have hair ⇒ Its genotype is hh
10) Fred has hair ⇒ Its genotype is HH or Hh
Possible crosses
11 and 12)
Cross1: If Fred was genotype HH and bred with Genevieve
Parentals) HH x hh
Gametes) H H h h
Punnett square) H H
h Hh Hh
h Hh Hh
F1) 100% of the progeny is expected to have hair and be heter0zyg0us, Hh.
13 and 14)
Cross2: If Fred was genotype Hh and bred with Genevieve
Parentals) Hh x hh
Gametes) H hh h h
Punnett square) H h
h Hh hh
h Hh hh
F1) 50% of the progeny is expected to have hair and be heter0zyg0us, Hh.
50% of the progeny is expected to be hairless and be h0m0zyg0us recessive, hh.
15)
• If the individual with the unknown genotype (Fred) is heter0zyg0us, the phenotypic rate of the descendants is 50% heter0zyg0us -Hh- and 50% h0m0zyg0us recessive -hh-.
• But if the individual with the unknown genotype is h0m0zyg0us dominant, the phenotypic rate of the descendants is 100% heter0zyg0us for the trait, Hh.
16)
The weakness is that even if Fred is heter0zyg0us for the trait, when making the cross it might occur that all individuals in the progeny are born h0m0zyg0us recessive, and there is a risk of missinterpreting the results.
So in that situation, many crosses must be done between fred and genevieve to se sure about Freds genotype.

Answer:
The types of waves that emanate from and earthquake are the body waves (P-waves and S-waves), and the surface waves. The surface waves travel along the suface, and are are the slowest, even though they do the most damage in an earthquake. While the P-waves travel the fastest through solids, liquids, and gases. S-waves, however only travel through solids.

a student is investigating cellular transport. what will most likely occur when the student places a cell that is 95% water inside of a solution that is 100% water?
Cellular transport refers to the flow of substances into or out of the cell across the cell membrane.
When the student places a cell that is 95% water inside of a solution that is 100% water, the cell will achieve net movement and if water continues to enter, it swells up and burst.
When a cell is placed in a hypotonic solution, water flows into the cells and the cell gains volume until it achieves equilibrium. But if water continues to flow in afterwards, it swells up and burst.Learn more about cellular transport: https://brainly.com/question/6949569
How do gravity work?
Answer:
Gravity makes the Earth constantly pull us down. ... The force of gravity depends on the mass (weight) of each object. The force with which two objects attract each other is proportional to their mass and decreases rapidly the moment we separate them.
Explanation:

Answer:
the closer objects are to each other, the stronger their gravitational pull is. Earth's gravity comes from all its mass. All its mass makes a combined gravitational pull on all the mass in your body.

Which process can cause chemical overheating
Answer:
Thermal Runaway
EX- Thermal runaway describes a process that is accelerated by increased temperature, in turn releasing energy that further increases temperature.
Explanation:
For a more simpler explanation , picture a pot of water and as you increase the volume of fire so does the energy (HEAT) inside . As air bubbles (ENERGY) start to quickly evaporate (BOILING) this actually increases the temperature inside causing Thermal Runaway.

if you have been to a beach for a whole day, then you have seen tides roll in and out. What causes
Earth's high tides?
Answer:
The Moon
Explanation:
High tides and low tides are caused by the moon. The moon's gravitational pull generates something called the tidal force. The tidal force causes Earth—and its water—to bulge out on the side closest to the moon and the side farthest from the moon. These bulges of water are high tides.
Answer:
it's caused by the gravitational forces from the moon.

an enzyme catalyses only one reaction explain why
Answer
Enzymes are proteins, which have a specific 3D tertiary structure, with a specifically shaped active site. The active site can only bind one substrate to form an enzyme-substrate complex, so can therefore only catalyse one reaction.

Determine whether each statement describes mitosis, meiosis, or both mitosis and meiosis.
Answer:
DNA replicates in both mitosis and meiosis, Mitosis occurs during growth and development, In meiosis the number of chromosomes reduce by half, Mitosis occurs in all organisms, Meiosis occurs in organisms that sexually reproduce, and chromosomes stay the same in Mitosis.
Explanation:
Mitosis: Occurs during growth and development, Occurs in all organisms, and The number of chromosomes remains the same
Meosis: The number of chromosomes reduces by half, and Occurs in organisms that sexually reproduce
Both: The DNA is replicated.
1. The DNA is replicated: Both Mitosis and Meiosis. In both processes, DNA replication occurs before the division of cells, ensuring that each daughter cell receives a complete set of genetic information.
2. Occurs during growth and development: Mitosis is the process responsible for the growth, repair, and development of multicellular organisms by producing identical daughter cells.
3. The number of chromosomes reduces by half: Meiosis involves two divisions that result in the reduction of chromosome number by half, leading to the formation of gametes (sperm and egg cells) with half the usual number of chromosomes.
4. Occurs in all organisms: Mitosis is a fundamental process occurring in various organisms, ranging from unicellular to multicellular, for growth, tissue maintenance, and asexual reproduction.
5. The number of chromosomes remains the same: In mitosis, the daughter cells have the same number of chromosomes as the parent cell, maintaining the chromosome count.
6. Occurs in organisms that sexually reproduce: Meiosis is specific to organisms that reproduce sexually, as it produces genetically diverse gametes that contribute to the variability of offspring.

!!!!NEED HELP ASAP ILL GIVE BRAINLIEST AND 25 POINTS!!!!! How do proteins help transport of materials through the membrane?
Answer:
Channel proteins can aid in the facilitated diffusion of substances by forming a hydrophilic passage through the plasma membrane through which polar and charged substances can pass.
Explanation:
Answer: By forming a continuous protein pathway across the membrane, these proteins enable specific hydrophilic solutes to cross the membrane without coming into direct contact with the hydrophobic interior of the lipid bilayer. Carrier proteins and channel proteins are the two major classes of membrane transport proteins.
