Answer:

D. homology

Explanation:

This observation is an example of the term known as homology. This is basically comparing how different species can have the same traits and physical design as each other even though they are completely different. This is due to the two species sharing a specific ancestor. That ancestor's trait is passed down throughout the generations even after the split and ends up in two different species.

Answer:

he germ cell split in half to create four gametes

Explanation:

Germ cells are the reproductive cells found in the male and female species. They are the cells that are responsible for the formation of the offspring through reproduction.

Germ cell splits two times in half to produce four gametes.

Therefore, germ cells divide two times to produce the gamete cells.

Answer:

by inhibiting cell-cycle regulators involved in adipogenesis  

Explanation:

Adipocytes are cells composed of adipose tissue and are specialized to store energy in the form of fat. In cell lines, it has been shown that adipogenesis can be inhibited through the use of inhibitory proteins, which function to arrest preadipocytes in the G1 phase of the cell cycle. These proteins are transcription factors that control cell-cycle progression by increasing gene expression of cell cycle inhibitors such as, for example, p21 protein. In the case of p21, this protein is a cyclin-dependent kinase inhibitor that binds and thus inhibits Cyclin-dependent kinases (CDKs), thereby controlling the progression of the cell cycle at the G1 and S phases.

Wool is the fabric which is soft, springy to touch and retain body heat.

Wool is a textile fabric obtained from sheep and other animals.

Fabric is a cloth or other material produced by weaving.

Soft means smoothness.

Springy means having elastic quality.

Touch means be in contact.

Retain means to absorb.

Answer:

One-fourth of the original carbon-14 isotope would be found in the wood today.

Explanation:

The half life of carbon-14 7000 years

Since the tree died and became a fossil 14000 years ago, number of times the tree has undergone decay in 14000 years = 14000/7000 = 2

Therefore, the carbon-14 would have undergone decay twice or passed through two half-lives

After one decay, 1/2 of the original sample remains

After another decay, 1/2 * 1/2 = 1/4 of the original sample remains.

Therefore, one-fourth of the original carbon-14 isotope would be found in the wood today.

Explanation:

Explanation:

photosynthesis the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

6CO2 + 12H2O + → C6H12O6 + 6O2 + 6H2O

Here, six molecules of carbon dioxide (CO2) combine with 12 molecules of water (H2O) using light energy. The end result is the formation of a single carbohydrate molecule (C6H12O6, or glucose) along with six molecules each of breathable oxygen and water.

Answer:

The process of photosynthesis is commonly written as:

6CO2 + 6H2O → C6H12O6 + 6O2.

This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

List the criteria in order of most to least important and assign each to a related sub-problem. In the rationale

According to his observations, Darwin proposed that the best-suited individuals in a population  would survive and  reproduce  more successfully than those less adapted to their environment, and  he called this natural selection.

This mechanism could account for both the unity and diversity of features among species. The  similarities between the descent organisms and their common ancestor explain the evolutionary adaptation of life, while the force of natural selection in different environments accounts for the population of life
