Jennifer observes a weather map showing tomorrow's weather. She predicts that air will travel from the low pressure system to the high pressure system, causing wind. The wind will carry moisture since it is coming from the ocean. Choose the statement which corrects the error(s) in Jennifer's prediction. (2 points)The wind from the ocean will not carry moisture.
The wind will travel from the high pressure system to the low pressure system.
Since the low pressure system is not over land, wind will not be created.
Wind is only created when two high pressure systems meet.
Answer:
Jennifer observes a weather map showing tomorrow's weather. She predicts that air will travel from the high pressure system to the low pressure system, causing wind. The wind will carry moisture since it is coming from the ocean.
Explanation:
Winds refers to the movement of air which are produced due to differences in air pressure.
These pressure differences are to uneven heating of the earth by the sun. Due to the uneven shape of the earth, regions around the equator receive a fairly consistent heating from the Sun. However, with increase in latitude north and south, there is more uneven heating of the earth's surface by the Sun. When air is heated, warm air rises up to the atmosphere. This produces a pressure difference and subsequently cold air sinks downward to replace it. This constant air movement results in winds. The winds generated moves from a high pressure system to a low pressure system. The greater the pressure difference, the greater the wind force.
When warm air from land rises, air from the ocean in to replace it. The wind coming from the ocean is moisture-laden, and results in precipation on land.

Which term best describes two predators living in the same habitat who feed on the same prey?
A.coexistence
B.mutualism
C.competition
Answer:
The answer is C, competition
Competition refers to the interaction between the organisms to seek or feed on the same resource.
The term that best describes the two predators living in the same habitat feeding on the same prey is competition.
Competition can be defined as:
Competition in an ecosystem or habitat will take place when the ecological niche of organisms overlaps as both organisms try to use the same resource. In habitat, the predators feeding on the same prey will have competition, as the predators will fight for food, nutrients, and a source of energy to survive. Competition can be caused among animals due to food, space, and shelter.
Thus, the correct answer is Option C.

Consider the following scenario: A drought hits the habitat of a semi-aquatic bird population. All ponds dry up, and fish populations decline. There are two groups of birds in the population that differ in leg length and diet. Long-legged birds eat fish, while short-legged birds eat insects. The drought has little effect on insect populations. What is the main selective pressure in this scenario?
leg length
insect population
drought
fish population
fish population
cuz i know :0
The main selective pressure in the given scenario will be on the fish population. Thus, the correct option will be D.
What is Selective pressure?The selective pressure can be defined as an evolutionary force that causes a particular phenotype to be more favorable in certain environmental conditions than other phenotypes. Selective pressures are the considered forces which can drive the evolution through the process of natural selection. Some phenotypes are more favorable than other phenotypes, depending on the external conditions.
Selective pressures can be detrimental or beneficial to certain phenotypes present within a population. The four main types of selection pressures are the biological factors, such as the predation and disease, the availability of resources, the climatic conditions, and the competition between different species.
Therefore, the correct option will be D.

. Some people taste the chemical phenylthiocarbamide (PTC) as intensely bitter, while others cannot taste it at all. PTC is similar to chemicals in broccoli, Brussels sprouts, and cabbage, among other plants. Tasting PTC is a dominant trait; non-tasting is recessive. About 51% of people of European descent are tasters. If all of the assumptions of Hardy-Weinberg equilibrium are met, then among people of European descent... a) What is the frequency of the non-taster phenotype
Answer:
The frequency of the non-taster phenotype among people of European descent is 49% or 0.49
Explanation:
Let us assume that the allele for tasting PTC is T, while that for not tasting PTC is t.
According to the Hardy-Weinberg equation : p² + 2pq + q² = 1
Also p + q = 1
Where p² is the frequency of individuals with the TT genotype for tasting PTC,; wow is the frequency of individuals with the heterozygous allele for tasting PTC, while q² is the frequency of the individuals with tt genotype expressed as the non-taster phenotype since the allele for tasting is dominant over that of the non-taster.
From the information provided 51% of people of European descent are tasters. Also, tasting PTC is dominant over non-tasting. This implies that individuals with TT genotype and Tt genotype will be phenotypically expressed as tasters.
Therefore p² + 2pq = 51% or 0.51
q² = 1 - p² + 2pq
q² = 1 - 0.51
q² = 0.49 or 49%
The frequency of the non-taster phenotype among people of European descent is 49% or 0.49

How does the crossing-over of chromosomes that occurs during recombination result in increased genetic variability in population?
THIS IS A TEST ANSWER
Answer:
they swap alleles
Explanation:
when homologous chromosomes cross over during meiosis, they exchange segments of DNA/swap alleles. this means that the chromosomes now have a completely unique combination of alleles, which causes variation. It is also random which of these unique chromosomes end up in which daughter cell (the gametes) and since fertilisation is a random and independent event, which unique male gamete that fertilises which unique female gamete is also random. This means the resultant zygote has a unique combination of alleles that is unlike either of their parents.

Answer:
Evolution means change in the physical features of an organism.
Explanation:
Evolution means change in the physical features of an organism. Evolution occurs in the population of an organisms due to various factors such as mutation, non-random mating and natural selection. Nonrandom mating occurs when an organism prefer mating with particular superior organisms or with the similar organism. Mutation in the genetic makeup of an organism is also responsible evolution. this mutation occurs when an organism experience ultraviolet radiation from the sun, or also occur if an error in DNA during cell division. Gene flow is also known as gene migration is the transfer of genetic material or traits from one population to another when the organism is migrated to another environment. Some organisms are selected naturally because they have the potential to survive in that environment so they survive and that doesn't adopt itself to the environment, it will extinct from the environment.

1. A student is completing a Punnett square for a trait (X/x) that is autosomal and inherited by the dominant allele. The father does not have it (xx), but the mother does (Xx). If they had two children, a son and a daughter, what would the completed Punnett square look like (i.e., would the son have the trait, would the daughter have the trait)?
A. Both children would not inherit the trait.
B.Both children would inherit the trait.
C. Each child has a 50% chance of inheriting the trait.
D. One child would inherit the trait and one child would not.
Answer:
C
Explanation:
autsomsal means that it is not x-linked/ realted to gametes. Dominate means that it needs only one X to get the trait
Using the punnet square
X x
x Xx xx
x Xx xx
there is 2 X which means there is a 50% change that their child will get the trait
In the punnett square analysis, each child has a 50% chance of inheriting the trait.
The mother Xx has the trait and the father xx doesn't.
Using the punnet square
Xx xx
Xx Xx xx xx
There are just two traits which are Xx and xx which are in equal frequency
and proportion.
This therefore means that the children have a 50% chance of getting the trait.
