Brown eye color in fruit flies is caused by a variation in a gene. What are two possible sources of this genetic variation?

Answers

Answer 1

Answer:

random mating

matution:a change in the chromosomes or genes of a cell

Explanation:

crossing over(or recombination) between chromotids or homologous chromosomes during meiosis

Answer 2

Mutation and Genetic recombination are two possible sources of this genetic variation.

What is Genetic Variation?

Genetic variation is defined as the difference in DNA between individuals or between populations where multiple sources of genetic variation include mutation and genetic recombination. Mutations are the ultimate source of genetic variation, but other mechanisms, such as genetic drift, contribute as well.

There are two main sources of Genetic variation which are as follows:

1. Mutation:

Mutation describes genetic variation caused by changes in the genes of individuals living in a population.

2.Genetic recombination:

Genetic recombination has been described as the fusion of gametes promoting different combinations of genes in a population leading to genetic variation.

Thus, Mutation and Genetic recombination are two possible sources of this genetic variation.

The alveoli are lined with mucus and are surrounded by a network of blood capillaries. They have very thin walls for gases to be absorbed through. An individual air sac is called an alveolus. The layer of moisture in the alveoli allows gases to dissolve so that they can diffuse quickly.

Explanation:

Photosynthesis is the process in which plants produce their food as well as food for other organisms. Thus, options A, B and D are correct.

What is photosynthesis?

Photosynthesis involves the conversion of light energy into chemical energy by plants.

Plants carry out photosynthesis in the presence of sunlight. They take up water and carbon dioxide to produce glucose and release molecular oxygen in the atmosphere.

This glucose is a six carbon sugar which can then be utilized to produce other carbon rich macromolecules.

Photosynthesis take place in the chloroplasts of the plant leaves.

Plant leaves contain green coloured chlorophyll pigment which traps the solar energy.

Only the green plants and some special bacteria carry out photosynthesis as chlorophyll is the reaction centre for photosynthesis.

Temperature, Light, moisture and carbon dioxide concentration are some of the factors that affect the rate of photosynthesis.

Therefore, photosynthesis is a prime event through which animals obtain their food and oxygen.

b. How does weathering affect Earth's surface?

Answers

Answer:

Weathering and erosion constantly change the rocky landscape of Earth. Weathering wears away exposed surfaces over time. The length of exposure often contributes to how vulnerable a rock is to weathering. Rocks, such as lavas, that are quickly buried beneath other rocks are less vulnerable to weathering and erosion than rocks that are exposed to agents such as wind and water.

Explanation:

Weathering describes the breaking down or dissolving of rocks and minerals on the surface of the Earth. Water, ice, acids, salts, plants, animals, and changes in temperature are all agents of weathering. Once a rock has been broken down, a process called erosion transports the bits of rock and mineral away. No rock on Earth is hard enough to resist the forces of weathering and erosion. Together, these processes carved landmarks such as the Grand Canyon, in the U.S. state of Arizona. This massive canyon is 446 kilometers (277 miles) long, as much as 29 kilometers (18 miles) wide, and 1,600 meters (1 mile) deep.
