Answer: A) the air temp at which the corn plants are grown
Explanation:
The independent variable is the one that changes based on what problem/ question the experimenter is trying to solve. The student is trying to see if the air temp has an affect on the rate of photosynthesis so they whorls use various temps and measure the rate
The constant in this experiment is the number of corn plants used.
WHAT IS A CONSTANT VARIABLE:
In an experiment, a constant or control variable is a variable that is kept the same for all groups of the experiment. The independent variable is tested to bring about a change in a dependent variable in an experiment. However, every other variable of the experiment must be kept constant. These variables are called CONSTANT.In this question, the independent variable is the air temperature while the dependent variable is the rate of photosynthesis.A constant in this experiment is the number of corn plants used. The number used must be the same for all groups.

A scientist crossed two fruit flies in a lab. She was studying the transmission of the alleles that affect wing shape. The dominant allele, C, is the allele for curly wings, and the recessive allele, c, is the allele for straight wings. She knew that one of the parent flies was heterozygous and had curly wings (Cc). Half of the offspring from the cross had curly wings, and the other half had straight wings. Identify the genotype and phenotype of the second parent fly. State the evidence that supports your response.
Answer:
The other fly would have to be a cc
Explanation:
To do this, you can use the square method, one Cc's on the top and one side a cc, when you cross these it gives you Cc, Cc, and cc, cc. Half and half.
Hope this helped!
The other parent was cc.
Genes often occur in pairs. Genes are units of inheritance located in the chromosomes. The pairs in which genes occur are called alleles. In a given pair of alleles, one gene is dominant and the other is recessive.
In this case, the dominant gene is for curly wings and the recessive gene is for straight wings. If one parent is Cc , the other parent must be cc causing half of the offspring from the cross to have curly wings, and the other half to have straight wings.

Which statement best accounts for the decline in bighorn sheep populations? 1. Predators of the sheep decreased in number. 2. Sheep ewes that have shorter, spiked horns increased in number. 3. Human activities directly and indirectly affected the sheep. 4. The sheep were listed as a "species of concern" by Glacier National Park.
Answer:
The statement which best accounts for the decline of the bighorn sheep population is - " Human activities directly and indirectly affected the sheep."
Explanation: Explaination of the following statements -
Predators of the sheep decreased in number.Predation is rarely considered a major mortality factor (Wishart 1975, 1978). It is well known that bighorn sheep are preyed upon, but there is little information available on the effect(s) of predation on the populations of bighorn sheep. Numerous citations document the stalking and/or killing of bighorn sheep by a number of predators.
Thus , this statement is not correct.
Sheep ewes that have shorter, spiked horns increased in number -The larger, wild relative of the domesticated sheep is the bighorn sheep. Males are called "rams" and have long spiral horns, while females are called "ewes" with shorter, spike-like horns. With white areas on the muzzle, the back of the legs and around the rump, the coat is short, coarse and usually brown. The sheep will shed its hair once a year to reveal a new coat underneath.Thus , the statement does not match with the decline of the bighorn sheep.
Human activities directly and indirectly affected the sheep. -: Disease transmission, human interference, overgrazing, and loss of habitat are often cited as factors responsible for decreases in the abundance and distribution of bighorn sheep. these all factors comes under the human activities which directly /indirectly results in the declination of the bighorn sheep.Hence, this statement is correct .
The sheep were listed as a "species of concern" by Glacier National Park.Home to 400 to 600 bighorn sheep, Glacier National Park lists the animal as a "species of concern," that is, at risk of being endangered. The research has also shown just how sheep-like bighorns could be. They're creatures of habit, that is. Therefore , the national park indicated the species at risk , but were not responsible for their declination.
Hence, this statement is incorrect.
Therefore , the correct answer is 3 ( Human activities directly and indirectly affected the sheep.)

Explanation:
Diffusion is the movement of molecules from an area of high concentration of molecules to an area with a ____ concentration.
A. Equal
B. Higher
C. Lower
D. None of the above
Answer:
lower
Explanation:
Diffusion is the movement of molecules from an area of high concentration to an area of lower concentration. So, the correct option is C.
What is diffusion?Diffusion is a type of passive transport, this means that it does not require any kind of external energy for movement of molecules. The difference in concentration in two areas gives rise to a concentration gradient. Where, in one area there is high concentration of molecules and in another, there is low concentration of molecules.
If the molecules move from an area of higher concentration to an area of lower concentration, they are moving along the direction of concentration gradient. This is why no additional energy is required. Diffusion is a type of passive transport where molecules move along a concentration gradient.
This is in contrast to active transport where molecules move against the concentration gradient and therefore require external energy.
Therefore the correct option is C.

Give an example of an adaptive radiation. Provide evidence to support the claim that the radiation originated with one or a few species, that it was rapid and the descendant groups occupy a wide array of ecological niches. Suggest a hypothesis to explain why the radiation occurred.
Answer:
An example of an adaptive radiation with evidence to support the claim that the radiation originated with one or a few species is discussed below in details.
Explanation:
The method of evolution of various classes in a given geographical area originating from a spot and spreading to other regions or habitat is described as adaptive radiation. For example, modifications in nozzles of finches on Galapagos island.
Adaptive radiation indicates the adaptation of an organism that allows it to favorably spread, or radiate, into other circumstances. Adaptive radiation commences to speciation and is only used to explain living organisms.

The fish in the first bowl couldn't have baby after baby after baby forever. The bowl filled up with fish and many fish died. A bowl this size can only keep three fish alive. What is it called when an area/home/ecosystem has a limit to the number of living things that can live there?
Answer: Carrying capacity
Explanation:
The carrying capacity can be defined as the ability of an ecosystem to sustain a particular number of members of the population of species in terms of availing resources for survival.
According to the given situation, the fish bowl is an ecosystem which can only sustain a particular number of fishes. Thus, the increase in the population of baby fishes was not supported by the fish bowl.
