Why can't organisms in a population follow the exponential growth pattern for a long period of time

Answers

Answer 1

Answer: because, even if they sustain a steady birth and death rate, food is bound to grow somewhat shorter at a certain point, and it will decrease. but in the absence of eating as much, the food has a short booming growth rate as well, which raises the organisms growth rate again, and it sustains this cycle of ups and downs. the same exact thing happens with its predators. another thing that can happen is a deadly disease, or a sudden heat wave or freezing period, or the finding of even more healthy food that create more production.
i hope this helps, and if it does a lot, can you please mark it as brainiest? (i usually don't ask this, but at the moment I'm kinda desperate.)

Describe the structure and function of fatty acid molecules, including the difference between saturated and unsaturated fatty acids

Answers

A fatty acid has two main parts: 1) a long hydrocarbon chain and 2) a carboxylic acid group. The hydrocarbon chain is how we can tell if it is saturated or not. If there are carbons-carbon double bonds, then it would be unsaturated. Saturated fatty acids have no double bonds.
Fatty acids are very important to the body for several reasons. They are essential to the structure of the cell membrane, they can be used for long term energy storage, healthy brain function, targeting molecules for many proteins, as well as cellular messengers.

Answer: Fatty acids are fats that have acidic carboxyl groups on them. Something like CH3-(CH2)n-COOH Unsaturated fatty acids have double bonds between 1 or more of the carbons in the chain. They are unsaturated with hydrogen, but can be hydrogenated chemically. Fatty acids have many roles, but a very common one is to form the lipids in membranes. In that case two fatty acids are usually joined to phosphate plus some others.

A biologist has found an organism she cannot identify while doing a census in a swamp. Which of the following would be the best characteristic to look for in order to decide whether this organism should be classified as a protist or as a plant?

Answers

A biologist has found an organism she cannot identify while doing a census in a swamp. The best characteristic to look for in order to decide whether this organism should be classifies as a protist or as a plant is….

Answer: B) If it is unicellular, it is a protist.

Although there are single celled archaea and fungi.

I hope it helps, Regards.

Answer:

The organism is classified as protist or plant based on whether is single celled or multicellular and whether it makes its own food.

Explanation:

Both, protists and plants are eukaryotic meaning that these have nucleus in their cells and organelles bound by membrane. Unlike plants which may be multicellular, protists are single celled. Hence, a botanist must investigate to find if the cells are multicellular or not.

Another important feature is that if the botanists finds that the organism produces its own food, then it is a plant. As plants get their own food by combining the sunlight captured with carbon dioxide from the air through process called photosynthesis.
