Answer:

c. Limits on population growth

Explanation:

Darwin was heavily influenced by Malthusian theory of how population growth was influenced by growth limits. For Darwin, the population growth of species of living beings would be influenced by the limits imposed by the environment in which these species live, through the amounts of natural resources available to the population.

Thus, Darwin concludes that when the environment allowed an abundance of natural resources, such as water and food, the population of living beings would tend to grow more, however, when natural resources are limited, the population would grow less. This is called "population growth limits".

An example of this can be seen in the question above, where finches that live in an isolated area have limited access to seeds and water.

Eric follows a vegetarian eating pattern, and he wants to know whether he needs to take any vitamin and mineral supplements. wha
Reil [10]

It would be most important for Eric to find out his <em>zinc, iron and vitamin B12 (or  riboflavin) levels, and ensure that he is obtaining adequate amounts of these vitamins and minerals through vegetarian sources </em>.

A vegetarian diet is typically low in zinc rich foods, since meat, shell fish and eggs are the most abundant sources of zinc. In order to ensure that he obtains sufficient zinc, Eric should make sure he consumes vegetarian zinc sources such as legumes, lentils, dairy, nuts and seeds on a daily basis.

Since iron and vitamin B12 are also difficult to obtain from vegetarian sources, Eric should consume iron rich foods such as spinach, kale, whole grains, broccoli, legumes,etc., on a daily basis. As for vitamin B12, daily supplementation of 2.4 μg is recommended for vegetarians. Alternatively, riboflavin fortified cereals and grains are also recommended to meet daily riboflavin requirements.

​rich sources of polyunsaturated fatty acids are found in ____. ​lamb ​sunflower oil ​milk ​egg yolk ​fish eggs
mihalych1998 [28]
Fatty acids are mostly composed of chains of carbon and hydrogen. Fatty acids without double bonds are "saturated" with hydrogen. When a fatty acid has one double bond, hydrogen is released therefore the fatty acid is "monounsaturated". When a fatty acid has two or more double bonds, then the fatty acid is "polyunsaturated". Unsaturated fatty acids are usually takes in the form of oils as they are liquid in room temperature (in contrast to saturated fatty acids which are solid in room temperature). Unsaturated fatty acids are usually found in plant based fats such as oils. Therefore the answer to this question is sunflower oil.

The sigmoid colon typically measures 25 to 40 cm in length (10 to 15.75 in). As a continuation of the descending colon, the sigmoid colon is a "S"-shaped section of the large intestine that starts in front of the pelvic brim and changes into the rectum at the level of the third sacral vertebrae.

<h3>The large intestine is it located in the pelvic cavity?</h3>
