A scientist measures the circumference of acorns in a population of oak trees and discovers that the most common circumference i

s 2 cm. what would you expect the most common circumference(s) to be after 10 generations of diversifying selection?

Disruptive selection or diversifying selection describes the changes in population genetics where extreme values for a trait are favored over intermediate values.

So according to this definition, the conclusion can be derived as :

The most common circumference(s) to be after 10 generations of diversifying selection will be greater than 2 cm and less than 2 cm.

The mammary glands enlargement during pregnancy primarily as a consequence of what hormonal process?
Masteriza [31]

Answer:

c-hormonal hyperplasia

Explanation:

When there is increase in the number  of cells and tissues that appear normal under the  microscope,Hyperplasia is said to occur.If these occur in cells of an endocrine gland of a system,then it is refers to as hormonal hyperplasia.

Therefore during pregnancy,the proliferation of the glandular epithelium  in a pregnant woman (and at puberty in a females are examples of hormonal hyperlasia.

Its possible causes are;

a  surge in local production s of growth factors,

In the numbers of growth factors receptors on the  cells receptive to the factors,

and   due to activation of   specific intrancellular signalling pathways.

Two test tubes are filled with a solution of bromthymol blue. A student exhales through a straw into each tube, and the bromthym

Explanation:

The plant is utilizing CO2 in photosynthesis

Photosynthesis produces glucose and O2 from inorganic CO2, light energy and water.

6CO2 + 6H20 + (energy) → C6H12O6 + 6O2

Bromothymol blue, an acid indicator, goes from blue to yellow when reacting with acid. The color change in sunlight  confirmed the use of CO2, dissolved within the solution as carbonic acid- its removal from the solution makes the more basic, and the solution goes from yellow (acidic) to blue (alkaline).

CO2 + H2O ↔ H2CO3

Further Explanation:

Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy in the form of molecules of glucose is produced from light, water and carbon dioxide while oxygen is released.

Occuring in several complex steps, photosynthesis is a rate limited reaction, it depends on several factors including carbon dioxide concentration, ambient temperature and light intensity; the energy is retrieved from photons, I.e. particles of light, and water is used as a reducing agent. Water supplies chlorophyll in plant cell with replacement electrons for the ones removed from photosystem II.

Additionally,

  • water (H2O) split by light during photolysis into H+ and OH- acts as a source of oxygen along with functioning as a reducing agent; it reduces the molecule NADP to NADPH by providing H+ ions and produces molecules of the energy storage molecule ATP through an electron transport chain.
  • This occurs in the thykaloids, where pigment molecules like chlorophyll reside.
  • Later, in dark reactions, NADP and NADPH are used in the Calvin cycle where monosaccharides or sugars like glucose are produced after the modification of several molecules. These store energy in their bonds, which can be released in respiration in the mitochondria.

In all eukaryotic cells mitochondria are small cellular organelles bound by membranes, these make most of the chemical energy required for powering the biochemical reactions within the cell. This chemical energy is stored within the molecule ATP which is produced. Respiration in the mitochondria utilizes oxygen for the production of ATP in the Krebs’s cycle via the oxidization of pyruvate( through the process of glycoysis). The electron transport chain, in which oxygen functions as the terminal electron acceptor occurs in both plants and animals.

3. Determine which would have fewer protein and DNA base
Pani-rosa [81]

Answer:

Chimpanzees

Explanation:

Chimpanzees are much more closely related to humans in an evolutionary sense that cows are. Chimpanzees and humans are both primates, characterized by features like advanced cognition, grasping hands and feet, and front facing eyes. In contrast, cows belong to a different of bovine animals.

Because we are evolutionary more related to chimpanzees, that means our DNA has undergone less change over evolutionary time. That means that the sequence will be more similar to chimps
