What is expected to happen to the death rate as population density and competition increase?a. decreases
b. increases
c. remains the same

Answers

Answer 1
Answer:

Answer: a. decreases

Explanation:

A population density can be define as the number of individuals in a population of a species living in a unit of area in a particular time. The population density can be influenced by number of births, deaths, immigration, emigration and competition. The number of live birth in a concerned population and immigration (introduction of the new members) are likely to increase the population density of a region. But the number of deaths and emigration (the members of the same population move to a new habitat), and the competition (the members of the same species may compete among themselves for the same resources, the superior one will receive the resources and the inferior one will loose and may die) will decrease the population density.

According to the given situation, death rate and competition among the individuals will likely to decrease the population density.

Answer 2
Answer: As the population density increases therefore we probably have an increase in birth rate, aslo less space becomes available to individuals and if competition increases that means we probably have an increase in fighting (contest competition) therefore there might be an increase in individuals dying. Therefore I would say the answer is (c) the increase in population density would cancel out the competition. Hope this helps :).

The process of linking monosaccharides to become polysaccharides is called __________, while breaking down polysaccharides, like glycogen, occurs during a process called __________.A: hydrolysis; dehydration synthesis
B: dehydration synthesis; hydrolysis
C: is crossed off
D: hydrolysis; glycolysis

Answers

The right option is B: dehydration synthesis; hydrolysis

The process of linking monosaccharides to become polysaccharides is called dehydration synthesis, while breaking down polysaccharides, like glycogen, occurs during a process called hydrolysis.

Dehydration synthesis is the process of linking two smaller molecules, or compounds, together to form a larger molecule following the loss of a water molecule.

Hydrolysis is the process of using water to break down a molecule such as carbohydrate into its component sugar molecules.


dehydration synthesis (releasing water to make covalent bonds); hydrolysis (using water to break covalent bonds)

How does the nervous system and endocrine system work together to send messages through the human body? A) The nervous system uses electrical signals, while the endocrine system uses chemical messengers. B) The nervous system uses hormones, while the endocrine system uses neurotransmitters. C) The nervous system and the endocrine system are entirely separate and do not work together. D) The nervous system and the endocrine system both use electrical signals to transmit messages.

Answers

Answer:

The answer is A: The nervous system uses electrical signals, while the endocrine system uses chemical messengers

Explanation: Your body uses electrical signals to move muscles and all types of things like that. The reason you can move your fingers on demand is because of your brain sending electrical signals. Now for pain your body uses chemical signals. Your brain sends out chemical signals letting you know that you are in pain in that specific area.
