Answer: The correct answer is -

D) giraffes having increasingly longer necks over time.

Natural selection is an evolutionary mechanism that was proposed by Darwin.

According to this mechanism, organisms that are better capable of adapting to their changing environmental conditions, survive and increase their number through reproduction whereas other are eliminated from the population.

Example - Long neck of Giraffe, which is much elongated, lofty stature, that was beautifully adapted for browsing on the higher tree branches. This was an adaptation with slow and gradual change in the gene frequency as the lower vegetation was eaten by other animals. Due to this, giraffes had to search for other source (that was higher tree branches).

This is considered as a peculiar example of natural selection.

How many rings does chlorophyll a and b have

In-s [12.5K]

Explanation:

Each has one chlorin ring- chlorin is a form of porphyrin.

Chlorophylls are comprised of a ringed molecule, chlorin, a hydrogenated form of porphyrin which contains a magnesium ion at the center, bonded to four atoms of nitrogen. Varying types of Chlorophyll have side chains, which affect the absorption spectrum of the molecule for instance A has a methyl group bonded to the C7 position, while B has an aldehyle (CHO) group at this location.

Embedded within the thykaloid membrane of chloroplasts, chlorophyll a and B mainly absorb orange-red and violet-blue wavelengths and convert light energy into chemical energy for the process of photosynthesis. This occurs in the light-dependent reactions of photosynthesis, within chloroplasts of plants. The range of wavelengths absorbed by a pigment is its absorption spectrum while it reflects those outside of this range. Plants appear green as this region of light is reflected by the pigments.

What kind of bond is broken and reform to release energy from food molecules

Andreas93 [3]

Answer:

Endothermic reactions absorb energy, so the sum of the energy required exceeds the amount that is released. In all types of chemical reactions, bonds are broken and reassembled to form new products.

Explanation:

Hope this helps!

Chemical reactions make and break the chemical bonds between molecules, resulting in new materials as the products of the chemical reaction. ... Breaking chemical bonds absorb energy, while making new bonds releases energy, with the overall chemical reaction being endothermic or exothermic.
