Answers
Answer:
D
Explanation:

To grow new somatic cells is the overall purpose of meiosis.
What do you mean by meiosis?Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells. It involves two rounds of division that ultimately result in four cells with only one copy of each chromosome.
The purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic complement of the parent cells. In the figures below, pink represents a genetic contribution from mom and blue represents a genetic contribution from dad.
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.

Human p53 is a tumor-suppressor gene located on chromosome 17. The function of this gene is to prevent cells with damaged DNA from undergoing mitosis. What would most likely result if there were a mutation that decreased the function of the p53 gene?
Answers
The answer is “Germs cells would undergo only one meiotic division.
Explanation:
I remember learning this in my biology class
Single amino acid changes in p53 caused by TP53 gene mutations make the protein less functional. Without p53, cell proliferation is not efficiently controlled, and DNA damage can build up in cells.
How p53 gene is important?Such cells might continue to divide uncontrollably, which would promote the development of tumors. By stopping the cell cycle to give the repair mechanisms time to restore genomic stability, p53 plays a significant function as a DNA repair facilitator.
Additionally, p53 adopted a variety of roles to directly influence the operation of different DNA-repair mechanisms.
Cancer cells may develop and spread throughout the body as a result of mutations (changes) in the p53 gene.
Therefore, numerous cancer kinds and the genetic disorder Li-Fraumeni syndrome have both been linked to these alterations.

Adult stem cells are best described as?
Answers
Explanation:
1 Definition. Adult stem cells are undifferentiated cells that reside among differentiated cells in a tissue or organ. They have the ability to renew themselves and differentiate into specialized cell types.
Adult stem cells, also known as tissue-specific stem cells or somatic stem cells, are multipotent cells that replace damaged and dying cells.
What are somatic stem cells?Somatic stem cells, also known as adult stem cells, are found in organs and tissues, have the ability to self-renew and give rise to the differentiated cell types that make up that organ or tissue (multipotency), and play an important role in the maintenance and repair of those organs and tissues. Adult stem cells are sometimes referred to as embryonic stem cells.
The bone marrow, the skin, the intestine, the brain, the blood vessels, the teeth, the reproductive system, and the heart are only some of the organs and systems in the body that include somatic stem cells.

What would be an appropriate key for these traits
Answers
Answer:
The correct answer is -
TT - short BB - blue eyes
Tt - short tail Bb - blue eyes
tt - no tail bb - brown eyes
Explanation:
In this given question it is stated that short tails of ribbits are dominant over the no tail trait of the rabbits and similarly blue eyes trait of the rabbits is also dominant over the brown-eye trait.
A dominant trait is represented by a capital letter and a recessive trait is represented by the small letter so for the tails alleles will be denoted as T and t, and for the eyes, the alleles would be B for blue and b for brown.
The key for these traits would be-
TT - short BB - blue eyes, due to both dominant allele,
Tt - short tail Bb - blue eyes, due to dominant allele masks the recessive allele
tt - no tail bb - brown eyes, due to both alleles are recessive

How was early Earth's atmosphere different from today's atmosphere?
Answers
Answer:
The early Earth was very different from our Earth today.
Explanation:
Earth's first atmosphere had lots of water vapor but had almost no oxygen. Later, frequent volcanic eruptions put several different gases into the air (Figure 12.13). These gases created a new type of atmosphere for Earth.
Answer:
The atmosphere we enjoy today is radically different from the atmosphere that formed with the Earth billions of years ago. ... As the Earth cooled enough to form a solid crust (4.4 billion years ago), it was covered with active volcanos. These volcanos spewed out gasses, like water vapor, carbon dioxide and ammonia.
How has the Earth's atmosphere changed over time?
Water vapor, carbon dioxide, methane, ammonia, and other gases similar to the ones produced by volcanoes today were expelled. Over a vast amount of time, millions of years, the earth gradually cooled. ... From these clouds, the oceans formed and the oceans absorbed a lot of the carbon dioxide in the atmosphere.

Which is a natural source of greenhouse gases?
Answers
Answer:
Examples of greenhouses gases are water vapor, carbon dioxide. methane, nitrous oxide and ozone (O3). Lightning produces ozone as does UV light at high altitudes, methane is produced biologically and in volcanoes (but doesn’t last long in the atmosphere). Carbon Dioxide is also produced biologically and in volcanoes. Water vapour is most from ocean evaporation, which is bad news if the Earth gets hotter because that leads to more Water vapour.
Explanation:
A natural source of greenhouse gases is respiration
Greenhouse gases are gases that trap heat in the atmosphere and warm the planet. The major greenhouse gases are:
Carbon dioxideMethaneWater vapor Nitrous oxide Fluorinated gasesThe greenhouse gases occur from natural sources and synthetic sources

Explanation:
Plant cells are different from the animal cells in their basic structure such as the cell wall which is absent in the animal cell, chloroplast is also found in the plant cell which is not present in animal cell.
What are Plant cells?Plant cells have a rigid cell wall, a large central vacuole, and plastids such as chloroplasts. The cell wall is a layer which is present outside the cell membrane and surrounds the cell, it provides the structural support and protection.
The central vacuole is present in the plant cell and it maintains turgor pressure against the cell wall. The central vacuole is a large vacuole found inside of plant cells. It is a sphere which is filled with fluid and molecules inside a cell. The central vacuole stores water.
Chloroplasts are the organelles which are responsible for the process of photosynthesis, are in many respects similar to mitochondria. Both the organelles including chloroplasts and mitochondria function to generate metabolic energy, evolved by endosymbiosis, and also contain their own genetic systems, and replicate by division.
