A finch population eats seeds that vary in size. There is variation in preference of seed type, and that variation positively co

rrelates with beak size. Currently, stabilizing selection is operating on beak size with little or no directional selection. Suppose more large seeds were to become available. What is a likely result?

Answer:

If larger seed became available, directional selection will act in favor of bigger beak finch.

Explanation:

In the case that more large seeds were to become available, then directional selection will start to influence in the beak size, favoring those individuals with bigger beaks. Those individuals with shorter beaks will start to disappear as these animals won't be able to eat the larger seed.

Directional selection <em>increases the proportion of individuals with an extreme phenotypic trait,</em> in this case, large beaks.

This selection presents more frequently in those cases in which <em>interactions between living organisms and the environment</em> modify in the same direction.

What is the primary product of light independent reactions
SOVA2 [1]

The primary products of the light independent reactions  (after one turn of the cycle) are:

a)  two G3P molecules

b)  three ADP

c) two NADP+

However ADP and NADP+ are not really "products". They are regenerated and later used again in the Light-dependent reactions.  Each G3P molecule is composed of three carbons.

For the Calvin cycle (Light independent cycle) to continue, 5 out of  the 6 carbons provided by the two G3P molecules are used to regenerate ribulose 1, 5 phosphate. Therefore there  remains only one carbon for the next turn of the cycle.

One  molecule of glucose requires 6 turns of the cycle. Any extra G3P is used to make starch, sucrose and cellulose.

Compare biomes of North Africa and iceland
Travka [436]

Answer with Explanation:

"Biome" refers to the flora (plant life) and fauna (animal life) of a particular place. It also includes the climate and specific conditions that allow the living organisms in the environment to survive.

The biome of North Africa consists of both desert biome and rainforest biome. It can be classified into a "savannah biome." This means that both the grassland and the woodland co-exist with each other. On the contrary, the biome in Iceland consists of a "tundra biome." The appearance of this biome is uniform and it is considered the coldest among all the other biomes.

Both of the biomes in North Africa and Iceland are different owing to their temperature, precipitation, nutrients from the soil and so on. The savannah biome consists of both wet and dry climates. These seasons allow the growth of both trees and grasslands. When it comes to the tundra biome, its temperature is extremely low. Thus, it doesn't allow many plants or trees to grow. However, it allows the growth of some unique types of wildlife such as the "Arctic fox."

Why are enzymes called a lock and key situation
IRINA_888 [86]

Because enzymes connect to their substrate through a lock-and-key system, where the shape of the substrate and the enzyme has to fit like puzzle pieces. Then only the enzymatic reaction can occur.
