Answer:

Coal, crude oil, and natural gas are all considered fossil fuels because they were formed from the fossilized, buried remains of plants and animals that lived millions of years ago. Because of their origins, fossil fuels have a high carbon content.

Environmental factors can influence natural selection because they can increase or decrease
olchik [2.2K]

Answer:

Environmental factors can influence natural selection because they can increase or decrease the amount of genetic variation in a population.

Explanation:

Natural selection is a process that involves the survival of species through changes in the expression of their genes, making possible the process of adaptation to environmental changes. It is one of the explanations for the biological evolution of species.

The second premise, necessary for natural selection to be possible, implies the existence of a variability (genetics) of traits among individuals in a population.

The other premises of natural selection are the faculty of traits to be inheritable and that genetic variability should lead to reproductive success and survival.

  • <em>The other options are not related to the process of natural selection, since it is not possible for natural selection to increase or decrease the number of chromosomes, in addition to the fact that genetic variability must be observed in a population, not in a single individual, to be considered natural selection </em>

As part of a science experiment, Jose did a test for starch on a slice of apple and a slice of potato. The yellow-orange iodine
Sever21 [200]
If iodine solution reacts with starch, it will change color into black.
Since the yellow-orange iodine solution stayed the same <span>color when it was put on the apple, it can be concluded that there is no starch in the apple. On the other case, the black color of the potato suggests that there is a great amount of starch in the potato. Anyway, this does not mean that there is no starch in the apple at all. As fruits ripen, starch slowly changes to sugar. Iodine cannot react with sugar, so the black color in the apple is missing.</span>

(a) What cell structures best reveal evolutionary unity?
xeze [42]

Answer:

The correct answer will be-

1. Evolutionary unity-  DNA

2. specialized cellular modifications- plant cells have chloroplasts and large central vacuole.

Explanation:

<u>Case I </u>

Evolutionary unity is a concept which explains that all the organisms possess some common structure or universal structure or molecules.

The best characterized evolutionary molecule is DNA molecule which took the role of genetic material in past and is passed on to the daughter cells and still is made up of the same components which are a five-carbon sugar, four types of nitrogenous bases and a phosphate group. This DNA molecule is present in almost every organism except for a few viruses.

<u>Case II </u>

The specialization of the cellular components depends on the function a cell has to perform which became established in the population. The plant cells depended on the sunlight to prepare food for themselves which was done by the chloroplast organelle which is absent in the animal kingdom.
