a. The logistic equation reflects the effect of density-dependent factors, which can ultimately stabilize populations around the carrying capacity. b. Density-independent factors have an increasingly greater effect as a population's density increases. c. High densities in a population may cause physiological changes that inhibit reproduction. d. Because of the overlapping nature of population-regulating factors, it is often difficult to precisely determine their cause-and-effect relationships. e. The occurrence of population cycles in some populations may be the result of crowding or lag times in the response to density-dependent factors.
Question:
Which of the following is an incorrect statement about the regulation of populations?
Answer:
b. Density-independent factors have an increasingly greater effect as a population's density increases.
Explanation:
A population can be defined as the total number of living organisms living together in a particular place and sharing certain characteristics in common.
Generally, these populations may be divided into a fraction of the population (subpopulation) based on certain factors and reasons.
Population change equation states that the change in the size of a population over a specific period of time is equal to the sum of the number of births and the number of immigrants that joined.
Mathematically, the population change equation is given by the formula;
Population Change = (Natality - Mortality) + (Immigration - Emigration)
Population regulation can be defined as a biological process that balances limiting factors affecting the growth of a population based on density. The factors that regulate the growth of a population are divided into two (2) main categories and these includes;
I. Density-independent factors.
II. Density-dependent factors.
Density-dependent are regulating factors such as predation, diseases, and competition that affect the size of the population of living organisms through decreasing or increasing mortality and birth rate.
Furthermore, density-independent factors do not have an increasingly greater effect as a population's density increases. Thus, its effect are reduced as a population's density increases in size.
What happens when the Earthis plates pull away from each other? What happens when they push together?
Answer:
Two plates pushed together create a convergent fault. If one plate is oceanic and the other continental, the edge of the oceanic plate will be pushed down. When two plates move away from each other they create a divergent boundary. When this happens under oceans, new ocean floor is created.

Which of the following is a nonrenewable resource?
O wind power
O geothermal energy
O oil
O solar energy
Answer:
Oil
Explanation:
Since, unlike oil, source like wind, solar, water etc. come naturally we don't and can't replace them but when the viscosity in oil has been used up it must be change to allow the proper functioning of the machine.
The next resource that is a nonrenewable resource is the oil that is present in the third option, as the oil is a fossil fuel that is formed over millions of years and is not renewable on human timescales.
What is a nonrenewable resource?Nonrenewable resources are natural resources that are finite and cannot be replenished or regenerated on a human timescale, and they are formed over millions of years, and their supply is limited, as oil is a nonrenewable resource that is formed from the remains of plants and animals that lived millions of years ago. These were buried under layers of sediment and rock, and over time, heat and pressure caused them to decompose and transform into oil, and the problem with nonrenewable resources like oil is that they are finite, meaning that there is only a limited supply of them.
Hence, the next resource that is a nonrenewable resource is the oil that is present in the third option.

In griffins, the allele for black feathers (B) is dominant over silver feathers (b) which are recessive. Two black griffins are crossed and have a silver offspring. What is the genotype of the parents?
Answer:
The correct answer is - Bb and Bb.
Explanation:
In this case, there are two traits decided by the black "B" allele that is dominant over "b" which is silver. In this case the cross between two black feather birds and the there would be genotype:
BB and BB or Bb and Bb or Bb and BB
1. In first case, and the third case, there is no or only one allele for the silver trait so the correct answer would be - Bb and Bb
B b
B Bb Bb
b Bb bb
thus, the correct answer is - bb which is silver feather.

Explanation:
whatr is the function of autotropns in the carbon cycle
Answer:
The biological carbon cycle
Autotrophs capture carbon dioxide from the air or bicarbonate ions from the water and use them to make organic compounds such as glucose. Heterotrophs, or other-feeders, such as humans, consume the organic molecules, and the organic carbon is passed through food chains and webs.

Fill in the space where it says hypothesis stated look in the photo I don’t have that much time
The purpose of the experiment is above
Answer:
The hypothesis of the experiment states that the density of a liquid can affect the properties and the way this liquid interacts with others.
Explanation:
In an experiment, the hypothesis is an assumption, that is, it is something that the researcher believes to be true. To confirm this assumption, the experiment must present facts that show that this assumption is correct and true.
In this case, the purpose of an experiment is to confirm a hypothesis. In this case, if the purpose of the experiment is to find out if the density of a liquid can affect the properties and how that liquid interacts with other liquids, it is because the hypothesis of this experiment assumes that the density of the liquid has the ability to modify the properties and the interaction of this liquid with others.

Why human beings are complex organism?
Answer:
human beings are complex organism because
humans are made up of billion cells and a lot of system and organ.like blood circulatory system,digestion system and so all
Answer:
Human beings are known to be complex organisms because they are made up of trillion of cell and organ systems that are dependent on each other. Some of the major systems are blood circulatory systems, the skeletal system, the digestive system, the nervous system and the respiratory system. Most of which are grouped into organ systems that have specialised functions.
The cells are organized from the simplest to the complex level in the body of the advanced organisms. These cells make up the tissues and then the organs. There is a division of labour among the cells which enhances efficiency and speed.

A company wants to test a new dog food that
is suppose to help overweight dogs lose
weight. Fifty dogs are chosen to get the new
food, and 50 more continue their normal
diets. After one month, the dogs are
checked to see if they lost any weight.
What’s the Independent variable, dependent variable, experimental group, and and control group?
Answer:
- Independent Variable: the new dog food
- Dependent Variable: weight loss in dogs
- Experimental Group: dogs that eat the new food
- Control group: dogs that continue with their normal diets
Explanation:
In a scientific experiment, the dependent variable is the variable being tested/measured, while the independent variable isn't changed by the other variables that are being measured during the experimental procedure. Moreover, the experimental group is the group of individuals/subjects that is exposed to the independent variable, i.e., they are exposed to the experimental treatment. Finally, a control group is a group that exhibits the same characteristics as the experimental group but doesn't receive the experimental treatment, thereby enabling comparisons with the experimental group.
What is a parasitic relationship?
a. One in which no members benefit, and none are harmed
b. One in which one member benefits, and the other is harmed
c. One in which one member benefits, and the other is unharmed
d. One in which both members derive some benefit
Answer:
b. One in which one member benefits, and the other is harmed
Hope this helps!!
Answer:
B
Explanation:
Think of a parasitic relationship as a parasite. One organism lives off of another, benefiting themselves, but not the host. An example would be a leech. A leech might attach itself to a human, sucking off its blood. The leech would benefit in this scenario and not the human.
