1) The Afrik aner population of Dutch settlers in South Africa is descended mainly from a few colonists. Today, the Afrik aner population has an unusually high frequency of the gene that causes Huntington's disease. Huntington's disease is an autosomal dominant disease and only one allele is needed for the disease (HH, Hh). The Afrik aners are an example of a founder effect. It is also an example of genetic drift. How is the founder effect related to the concept of genetic drift?

A) Reduced genetic variation of this small population means that the population may not be able to adapt to new selection pressures.
B) In a small population, the more advantageous trait becomes more common. If this continues, eventually, all individuals in the population will have Huntington's disease.
C) The small population size means that the new colony may have reduced genetic variation from the original population and that variation, in this case, included the dominant allele for Huntington's disease.
D) There are three sources of genetic variation: gene flow, se xual reproduction, and mutation. In the case of the Afrik aners, once the settlers arrived in Africa, these three sources had little impact on the gene pool and variation.

Answers

Answer 1

Answer:

C.

Explanation:

The small population size means that the new colony may have reduced genetic variation from the original population and that variation, in this case, included the dominant allele for Huntington's disease. Genetic drift, along with natural selection, mutation, and migration, is one of the basic mechanisms of evolution. In this case, it was a chance that the settlers all carried the allele for Huntington's disease.

Answers

The answer is Cell wall

The tough and rigid layer that surrounds plant cells, as well as some algal and bacterial cells, is called the cell wall. Therefore, the correct statement is option A.

What are the functions of cell wall?

The cell wall provides mechanical support to the cell, thereby, protecting it from damage caused by external factors. The cell wall consists of complex carbohydrates, such as cellulose, lignin, etc.

The cell membrane is selectively permeable, and the cell wall is porous allowing the passage of some molecules. The cell wall also helps in cell communication and signaling.

The cell wall determines the shape of the cell and helps in the regulation of growth and development. The thickness and composition of the cell wall change with respect to different environmental conditions and helps in the survival and function of many types of cells.

A species of moth has a 2 varieties of wing color: brown and white. As winter approaches, the trees where the moths live loose their leaves. The moth's predators are birds who hunt for the moths as they rest on the dark tree bark. Every moth lays 100 eggs, but only about 10 from each egg cluster live to adulthood

Answers

Assuming that this question makes reference to the survivability of the two moth variations, we can confirm that the brown-colored moth will be better adapted to survive in the winter months.

Why are the brown moths more likely to survive?

This has to do with their ability to better hide from predators. As described in the question, their primary predator are birds that hunt them while resting on the tree bark. This means that the white-colored moths will stand out against the dark tree bark and be easier prey for the birds. This will eventually lead to all the moths in the area being brown-colored through the process of natural selection.  

Therefore, we can confirm that the brown-colored moth will be better adapted to survive in the winter months due to their ability to hide from predators.

Explanation: The sun has extremely important influences on our planet: It drives weather, ocean currents, seasons, and climate, and makes plant life possible through photosynthesis.

Answer:

no it cannot sustain itself without the sun.

Animals need the sun for vitimin D plants need it to photosynthesis and in the few cases that this isn't the case those plants are parasitic and still need photosynthesing plants to get energy from. So by removing the sun we lose plants that many herbovore animals rely on then they starve resulting in lose of food for carnivores so they starve aswell.

The method of moth control would be most dangerous to the honeybee, which is needed for plant pollination is spraying plants with insecticides.

What is pollination ?

Pollination is the transfer of pollen from a plant's anther to its stigma, allowing fertilization and seed production, most commonly by an animal or by wind.

Pollination is the transfer of pollen grains from stamens, the flower parts that produce them, to ovule-bearing organs or to the ovules (seed precursors). Pollen is simply caught in a drop of fluid secreted by the ovule in plants where the ovules are exposed, such as conifers and cycads.

Pollination is the process of moving pollen grains from the anther to the stigma of the same or different flowers. Self-pollination and cross-pollination are the two types of pollination.
