The beak size in a species of bird is influenced by a gene for which only two alleles exist. The allele that results in a large beak is dominant to the allele that results in a smaller beak. If introduction of a new food source causes the birds with smaller beaks to be better fit to survive, which of the following will most likely happen?
The allele for small beaks will become dominant to the allele for large beaks.
The bird population will decrease as the recessive allele becomes more common.
The birds with large beaks will die out as a result of lack of food.
The frequency of the allele that results in small beaks will increase.

Answers

Answer 1

Answer:

I think that the birds with large beaks will die out as a result of lack of food. (c)

Explanation:

If the smaller birds are better fit to survive then selective pressures should decrease the number of birds with larger beaks.

write any three methods of controlling flood landslide and soil erosion​

Answers

You can reduce soil erosion by:
Maintaining a healthy, perennial plant cover.
Mulching.
Planting a cover crop – such as winter rye in vegetable gardens. ...
Placing crushed stone, wood chips, and other similar materials in heavily used areas where vegetation is hard to establish and maintain.

Floods can be controlled by redirecting excess water to purpose-built canals or floodways, which in turn divert the water to temporary holding ponds or other bodies of water where there is a lower risk or impact to flooding.

modifying slope geometry, using chemical agents to reinforce slope material, installing structures such as piles and retaining walls, grouting rock joints and fissures, diverting debris pathways, and rerouting surface and underwater drainage.

why would you expect Greenland to have a higher albedo than its surrounding areas?

Answers

The albedo of the ice sheet is high in winter when much of Greenland is covered by fresh snow.

Greenland is filled with ice and has a higher reflectance rate as in winters it's covered with fresh snow.

Where is Greenland?

The greenland is an island nation and lies between the arctic and Atlantic ocean. Has an area of  2.166 million square km and is among the largest island in the world.

It has the third-largest area in North America after Canada, The lowest temperature is recorded in Greenland in the northern hemispheres. Greenland is Greenland snow is thick and fresh in winter this creates a higher albedo.

Describe the scientific explanations of the origin of life of Earth.

Answers

RNA World has been the prevailing theory for the origin of life since the 1980s. The emergence of a self-replicating catalytic molecule accounts for signature capabilities of living systems, but it doesn't explain how the protobiological molecule itself arose.

The scientific experiment on the origin of life on earth is according to the RNA world hypothesis, which is supported by many scientists, RNA rather than DNA was the earliest genetic molecule of life on Earth.

What is the origin of life on earth?

The natural process through which life emerges from non-living materials, such as simple organic compounds, is known as abiogenesis or biopoiesis. Abiogenesis theories can be broken down into three basic stages: geophysical, chemical, and biological. Therefore, biogenesis, protobiogenesis, and biopoiesis are other terms for the origin of life.

Although the signature traits of living systems are explained by the creation of a self-replicating catalytic enzyme, the origin of the photobiological molecule itself is not explained.

Therefore, according to a scientific experiment on the genesis of life on Earth, RNA rather than DNA was the first genetic molecule of life on Earth.

Sustainable forestry: seeks to conserve forests for the long-term commercial harvest of timber and non-timber forest products by maintaining a mix of forest trees, by age and species, rather than imposing a monoculture. due to the complexity of goals, is most effective when it involves cooperation among environmentalists, loggers, farmers, indigenous peoples, and local, state, and federal governments. approaches vary from one forest ecosystem to another, in response to different environmental, cultural, and economic conditions. is all of the above.

Answers

Answer:

Yes, it is all of the above.

Explanation:

Yes, all the above statements are necessary for sustainable forestry because trees and other wild plants of the forest are necessary for all farmers, loggers, environmentalists, indigenous peoples and for the governments. The environmentalists study on these plants to find out the impact of these different plants on the environment, the farmers cultivate trees and plants to get money by selling it, the employment of loggers also related to these forests and the indigenous peoples also gain benefits by gaining food as well as medicines from it. This forest also fulfill the needs of wood and other products of the country.

The United States is often called the "melting pot" because people from all nations have made a home here. If someone has a grandmother from Brazil, for example, that came to live in the US, would relocating to Chicago change her grandkids’ skin tone phenotype? Why or why not?

Answers

Answer:

Technically no

Explanation:

Technically no. The skin tone of the individual is caused by two factors, one is genetic and the other is environmental. The genetic factor will continue being there since the grandkids would be descendants of the grandmother. The environmental factor can change skin tone phenotype over the course of an individual's life. Although in this scenario, both locations have the same type of weather. Both Brazil and California are incredibly hot locations all year round.
