Ehrlich and Raven hypothesized that if a new defensive trait evolves in a single plant species (or if a new trait to counteract

a plant's defenses evolves in an herbivore species) the appearance of that trait could result in a period of species diversification. Their hypothesis is also referred to as the _____ hypothesis.

Answer:

Coevolution

Explanation:

Ehrlich and Raven observed butterfly species and their host plants. Plant species had adopted a series of defence mechanisms against butterflies. In response the butterflies also evolved new traits to avoid these defence mechanisms.

In this way both butterflies and plants influenced each other's traits and they co evolved. The coevolution can lead to accumulation of lot of different characteristics which can lead to formation of new species and species diversification. Formation of new species will be observed both in plants and butterflies.

As temperatures increase, gases such as CO2 diffuse faster. As a result, plant leaves will lose CO2 at a faster rate than normal
3241004551 [841]

Answer:

See the answer below

Explanation:

If the amount of light reaching a leaf and the water supply is adequate in the face of inadequate carbon dioxide, the <u>latter becomes a limiting reagent in the process of photosynthesis. </u>

The process of photosynthesis has two steps

1. The light reaction

2. The light-independent reaction/the Calvin cycle

<em>Carbon dioxide is only required in the second step which is the Calvin cycle. This means that the light reaction proceeds at a normal rate but the Calvin cycle is slowed due to inadequate carbon dioxide. Overall, the rate of photosynthesis becomes limited to the amount of carbon dioxide that is available in the leaf.</em>

damaskus [11]

A covalent bond in which the electrons are shared unequally is called a(n) polar covalent bond. The atoms of the bond have partial negative and positive poles due to unequal electron distribution.

An electron exchange that results in the formation of electron pairs between atoms is known as a covalent bond. When atoms share electrons, a stable equilibrium of the attractive and repulsive forces between them is known as covalent bonding. These electron pairs are also known as shared pairs or bonding pairs. Since most interactions between carbon molecules include covalent bonds, covalent bonds are particularly significant. By sharing electrons with other molecules through covalent bonds, molecules can form extensive chains of compounds.

When atoms are distributed unevenly in a covalent connection, a polar covalent bond develops. Specifically, when the two atoms in the bond have electronegativities that range between 0.4 and 1.7. Polar covalent bonds and polar bonds are frequently used interchangeably.
