Answer:
Population growth decreases as the population density increases.Explanation:
This may be true for non-human populations but our species has developed the ability to modify the environment to sustain a huge population size.
Population growth decreases as the population density increases. If the individuals of a population are less and spaced widely apart, it may seldom encounter one another, making reproduction rare.
What is population density?Population density can be defined as the average number of people reside in a given area and it is calculated by dividing the total number of people in a certain area by the size of the area.
The measurement of population density is normally represented as the number of people per square kilometer, several physical factors like space constraints, land topography, resources, and climate can affect population density.
Other Human factors like politics, lifestyle, and economics can affect population density; Extreme climate means too cold, hot, wet or dry, too high and too steep, Infertile land

Which of the following could NOT be determined from using the law of superposition?
A.
That a sedimentary layer is older than the one above it
B.
That a sedimentary layer is younger than the one below it
C.
That a sedimentary layer is 100 million years old
D.
That a sedimentary layer contains fossils older than those in another layer
Answer:
C, that a sedimentary layer is 100 million years old.
Explanation:
The law of superposition functions without regard to exact times, basing its times relative to the layer above or below it. Without the age of a specific layer being giver in advance, you will not be able to determine the specific age of the layer being examined, only a relative age.
if sally marries a man who is an asymptomatic carrier for alkaptonuria, what is the probability that they would have a son with alkaptonuria
Alkaptonuria is passed down through the generations as an autosomal recessive condition. When an individual receives the same faulty gene for the same trait from both parents, they are said to have recessive genetic diseases. If a person is born with one normal gene and one illness gene, he or she will be a carrier for the disease but will not display symptoms. With each pregnancy, there is a 25% chance that two carrier parents will both carry the faulty gene and, as a result, have an afflicted child. With each pregnancy, there is a 50% chance of having a child who is a carrier like the parents. A child's chance of receiving normal genes from both parents and being genetically normal for that attribute is 25%.
The risk is the same for males and females alike.
skunk vs panda. Who will win?
Answer: Skunk
Explanation: The panda will try to use their slow attack, but the skunk will counter it with their stinky spray that smells bad and the panda will run away.
Describe the founder effect.
The founder effect is the loss of genetic variety that happens when a new population is founded by a small number of individuals from a larger population, according to population genetics. Ernst Mayr was the first to thoroughly explain it in 1942, based on previous theoretical work by people like Sewall Wright.

Which one of these mollusc groups is classified as suspension feeders?.
Which one of these mollusk groups can be classified as suspension feeders?
bivalves
Bivalves is molluscan groups is classified as suspension feeders.
What are molluscan?It includes well-known creatures including clams, scallops, oysters, chitons, octopuses, and squid. Some lesser-known subspecies of mollusks, such as the monoplacophorans, were originally believed to be extinct for millions of years till a specimen was discovered in 1952 in the deep water off the coast of Costa Rica.
The second-largest animal phylum, Mollusca, contains more than 100,000 species. The molluscs contain numerous well-known creatures, such as clams, snails, slugs, and squid, as well as some uncommon creatures, such as tusk shells and chitons.
Molluscs can be found in almost every freshwater and marine environment, as well as on land in some cases.
Therefore, Bivalves is molluscan groups is classified as suspension feeders.

A man has type A blood and his wife has type B blood. A physician types the blood of their four children and is amazed to find one of each of the four blood types. He is not familiar with genetics and calls upon you to explain how such a thing could happen. What would you say? Explain using a description of the parental allele possibilities.
Answer:
Explanation:
There's nothing to get amazed to find all the four types of blood groups in the progeny, provided the parental genotypes are AO and BO.
The four types of blood groups included A, B, AB and O.
Had the parental genotypes been AO and BO, the progeny would include all the four blood groups A with genotype AO, B with genotype BO, AB with genotype AB and O with genotype OO.
It happens only in this case and not in any other as the alleles A and B are co dominant to each other and completely dominant over the allele O.

Which term refers to the energy an object has due to its position? A Electrical energy B. Potential energy C. Thermal energy D. Kinetic energy
Answer:
Option B
Explanation:
Using the process of elimination, we will find this answer.
It's not option A because electrical energy involves electricity and has nothing to do with motion/position, although you can build machines fueled on electrical energy to create motion or position. (Hence; vehicles)
It is option B because potential energy is energy the object has when it's at rest, which means when the object remains in the same position it has potential energy.
It's not option C because thermal energy involves heat which you could use heat energy and convert it into electrical and then build a machine that is fueled on electrical energy that creates motion or position. (Hence; boats)
It's not option D because Kinetic energy is purely energy when a object is in motion, has nothing to do with a position of a object. As long as the object is moving it has kinetic energy.
Your answer is option B or "potential energy."
