Answer:
splits into two or more genetically distinct descendant populations
Explanation:
New species form by speciation, in which an ancestral population splits into two or more genetically distinct descendant populations. Speciation involves reproductive isolation of groups within the original population and accumulation of genetic differences between the two groups

Which letter in Figure 1 represents meiosis? Why?
Which letter in Figure 1 represents mitosis? Why?
The letter D in Figure 1 represents meiosis, while letter A represents mitosis. Meiosis is a reductional cell division.
Mitosis is a type of cell division where a parent cell divides to produce two genetically identical daughter cells (in this case, diploid cells).
Meiosis is a reductional cell division where a parent cell divides twice to produce four daughter cells having half of the genetic material.
Meiosis occurs in germinal cells, while mitosis occurs in somatic (body) cells.

what is the difference in solubility of triglyceride and the products of their hydrolysis
Answer: Triacylglycerols are the major constituents of oils and fats of both plant and animal origin.
Explanation:
Hope this helps.
The products of hydrolysis of triglycerides are fatty acids and glycerol. While fatty acids, like triglycerides, are insoluble in water, glycerol is soluble in water.
Why are triglycerides insoluble?Triglycerides are esters of fatty acids and alcohol, mostly glycerol. The fatty acid chains are inked to the glycerol molecules with the help of covalent bonds.
This means that the triglyceride molecule is uncharged and will therefore remain insoluble in water but soluble in organic solvents.
Also, products of hydrolysis of triglycerides are fatter acids and glycerol. While fatty acids will remain insoluble in water, glycerol is soluble in water.
Glycerol is alcohol with 3 hydroxyl groups, this is why it is also called a polyol. They are able to hydrogen bonds with the nearby water molecules.
Therefore, triglycerides and fatty acids are insoluble and glycerol is soluble in water.

The changes that occur during the 3rd week of the menstruation cycle is
the egg travels through the fallopian tube to the uterus.
Ovulation is the process that takes place during the 3rd week of
menstruation. The Luteinizing hormone (LH) stimulates the release of the
egg from the ovary and travels through the fallopian tube to the uterus.
At this stage, the individual has a higher chance of getting pregnant when
unprotected sex occurs.

Which of the following adaptations helps alpine animals survive the cold winter? a. Reduced lung size b. Low levels of hemoglobin c. Hibernation d. Large legs, ears, and tails.
Hibernation is an adaptation that helps alpine animals to survive the cold winter. Hibernation helps to store energy.
Hibernation is an adaptation that helps to store energy by decreasing the metabolic rate.
This adaptation (hibernation) is observed in animals living in extremely cold conditions (e.g., alpine animals).
The hibernation adaptative strategy is characterized by an excessively low temperature in the body, slow breath rate, slow beats (heart rate), and low metabolic rate.

A population of rhinos in Africa is 112. this year there were 17 births and eight deaths in the population. What is the change in population? Do we have a positive, negative, or zero change in population? How many members are in the new population?
Answer should contain the following information: work for calculating the change in population positive, negative, or zero change in population. work for calculating the new population
Explanation:
Why anti-poaching?Rhinos have inhabited the African continent for over a million years and they play a huge role in their ecosystems. The illegal trade in powders made from their horns, which in some countries in Asia is still considered a medicine or simply a symbol of wealth, nearly led to the extinction of the African rhino.
In 1875, there were still more than 1,000,000 rhinos living in the vast grasslands of Africa. Today the populations of the two species of black rhino and white rhino are estimated to contain about 5,000 and 20,000 animals respectively. The senseless killings continue. Since 2007, the number of rhinos hunted in Africa has increased by almost 9,000%.
It is therefore our call to stop the slaughter of rhinos with all our might.
