Which of the following best describes a form of genetic drift in which the animal population is depleted, thereby reducing the population's genetic diversity?
A. bottleneck effect
B. disruptive selection
C. founder effect
D. gene flow
The bottle neck effect best describes a form of genetic drift in which a population of animals becomes smaller, thereby reducing the genetic diversity of the population. So, the correct option is A.
What is the Bottleneck effect?The bottleneck effect occurs when population numbers are dramatically reduced as a result of natural disasters such as earthquakes, floods, and other natural disasters. The new population is composed of organisms that were able to survive the catastrophe whose allele frequency will be radically different from the original allele frequency.
The bottle neck effect best describes a form of genetic drift in which a population of animals becomes smaller, thereby reducing the genetic diversity of the population.

How did the polar bears get their white fur?A.Bears have various alleles for fur color ranging from dark to light. Those bears with the lighter fur had a better chance of survival in the biome, so they lived and reproduced passing on their light colored gene to their offspring. As generations passed, white fur became more common.B.As a polar bear grows up, its fur gradually gets lighter, so by the time they are a teenager, they have fully white fur and are then best suited to survive in their environment.C.Polar Bears migrated from the Pacific Northwest up to the Tundra and Arctic because they knew that they would have a better chance of surviving in this cold region.

In what year should we expect ocean pH to adversely affect zooplankton population?
The year we should expect ocean pH to adversely affect zooplankton population is 2030.
What are zooplanktons?Zooplankton is a small floating or weakly swimming organisms that drift with water currents and, with phytoplankton, make up the planktonic food supply upon which almost all oceanic organisms are ultimately dependent.
Ocean acidification may affect zooplankton directly by decreasing in pH, as well as indirectly by trophic pathways, where changes in carbon availability or pH effects on primary producers may cascade up the food web thereby altering ecosystem functioning and community composition.

Answer:
Protect coastlines from storms, erosion and provide habitat.
Explanation:
Coral reefs protect coastlines from storms and erosion as well as provide a habitat for thousands of aquatic animals. These points rashid must include in his seminar. Coral reefs are very important for the marine ecosystem because it can save the soil from erosion and decreases the intensity of storms by acting just like barrier. It provides food as well as living place for many organisms so these point are very important to be included in the seminar.

Explain how nitrate ions help plants to grow.
Answer:
Explanation:
Both nitrate ions and ammonium ions can be taken up by plants (some prefer one to the other). These ions provide nitrogen for the plant to make its own amino acids for protein synthesis. Except in very high nitrogen soils, the addition of extra nitrate will stimulate plant growth.
Nitrogen is an essential macronutrient that is a component of many essential molecules, such as amino acids, proteins, nucleic acids, and chlorophyll.
What are the roles of nitrate in the growth of plants?Nitrate ions are essential nutrients for plant growth and development. Nitrogen is the fourth most abundant element in plants and is crucial for the growth of leaves, stems, and roots.
Plants require nitrogen in the form of nitrate because it is the most oxidized. It is an easily available form of nitrogen for plants to take up from the soil. Nitrate is absorbed by plants through their roots and transported to the plant cells, where it is used to synthesize amino acids, proteins, and other essential molecules.
Nitrate plays a crucial role in the process of photosynthesis, which is the process by which plants convert sunlight into energy.

Before cellular division, the cell must duplicate its DNA so that the daughter cells will contain complete copies of the dna. Which characteristic of DNA makes it most suitable as a molecule for this role?
A. DNA is located in the nucleus
B. DNA is a large macromolecule
C. DNA is made of repeating sugar-phosphate subunits
D. DNA is made of two strands of complementary nucleotides
Answer:
D. DNA is made of two strands of complementary nucleotides
Explanation:
As rightly stated in this question, DNA replication must occur prior to cell division because each daughter cells must receive an equal and correct amount of genetic material (DNA). DNA replication is the process by which the DNA molecule duplicates to form two identical copies of itself.
This replication characteristics of DNA is achievable because "DNA is made of two strands of complementary nucleotides". The double-stranded DNA first unwinds into two single strands. After which, each single strand serves as a template for the new DNA strand. Two strands of a DNA molecule are complementary to one another.
