You have been looking at meiosis beginning with a diploid cell that has the genotype AaSs. The alleles in the haploid gametes produced by meiosis are
Answer:
AS, As, aS, as
Explanation:
Meiosis is the cell division that involves the production of daughter cells or gametes with a reduced number of chromosomes. i.e. diploid (2n) - haploid (n).
According to Gregor Mendel in his law of Segregation, the alleles of a gene will separate into gametes in such a way that only one allele will be present in each sex cell. Hence, in this diploid cell with genotype AaSs, the alleles will separate into the haploid cell in the following genotype proportion:
AS, As, aS, and as
what is a CER please help !!!!!!!
Answer:
Claim-Evidence-Reasoning
Explanation:
hope it helps
Answer:
CER(S) Stands for Claim, Evidence, Reasoning, Science
Explanation:
The 1st part of CER(S) is a CLAIM. A claim is a simple, single sentence that answers a question. Your claim is a statement about what you believe to be true about that question. Your claim must be accurate, clear, and exact. Your claim should be the first sentence in your explanation. Your claim should ONLY answer the question – do not explain your answer at this point.
The 2nd part of CER(S) is EVIDENCE. Evidence consists of data and/or results that can be used to support the claim. Evidence must be explicitly stated in sentence form and cannot merely be referenced. To adequately support a claim, the evidence must be appropriate (relevant to the question) and sufficient (enough provided to be convincing).
The 3rd part of CER(S) is the REASONING. Reasoning ties the evidence to the claim and explains why the evidence supports your claim. In this section you discuss why the evidence that you provided is important and relevant to your claim.
The 4th and final part of CER(S) is the SCIENCE. Your teacher may not ask you to provide the supporting science for every CER(S) question – that is why the S is in parentheses. If you are asked to provide the science that supports your claim, then you need to discuss the relevant science and how it supports your claim.

Answer:
Explanation:
first day at the desert most of my hours will be spent making shelter for safety and then in the evening hunting is done for food.
Pineapple has an alternative way of opening without knife, which is to hit and roll on the ground severally exerting little force this allow the hard shell to be loosely packed and can be easily removed with hands from each box on the pineapple body.
The best way to maximize time is to do the most important and tedious work first.
Having limited tools to work with because it is a desert is a major challenge

Which correctly lists the three main ocean zones?
O deep, neritic, surface
O intertidal, deep, surface
O neritic, intertidal, open ocean
O open ocean, deep, continental
Answer:
Honestly I think it's C
Explanation:
The three main ocean zones are neritic, bathyal, and abyssal. Therefore, none of the statements are correct.
What are the three main zones?The ocean is divided into three main zones which are the neritic zone. This zone is the shallowest zone extending from the shoreline to the edge of the continental shelf and is 200 meters deep.
The bathyal zone is the middle zone extending from the edge of the continental shelf to the abyssal plain and is 4,000 meters deep. The abyssal zone is the deepest zone extending from the abyssal plain to the ocean floor.
Apart from the three main ocean zones, there other oceanic zones are epipelagic zone, mesopelagic zone, and hadal zone. The hadal zone is the deepest oceanic zone and is unique to highly adapted species of marine life and is important to study.
Therefore, the three main ocean zones are neritic, bathyal, and abyssal.

Halfway through exponential phase, the temperature is lowered slightly below the
optimum. How will the growth curve change?
A. The cells will immediately enter death phase
B. The cells will enter lag phase
C.The slope of the exponential phase will become shallower
D. The slope of the exponential phase will become more steep
Which one is the best answer ? Choose only one answer
Answer:
B. The cells will enter lag phase
Explanation:
There are four identifiable phases of bacterial growth in a culture. These are: the lag phase, the exponential or log phase, the stationary phase, and the death or decline phase.
The lag phase occurs when there is need for the growing bacterial cells to adapt to new conditions. The adaptation period, i a time when the cells adjust themselves to the new conditions. The length of the lag phase varies considerably, depending on the initial and final conditions of the bacteria cells.
Hence, when the temperature is slightly lowered below the optimum halfway into the exponential phase, the cells will enter into lag phase

The hypoxic zone in the Gulf of Mexico is not unique; at least 200 dead zones exist at estuaries and along seacoasts worldwide. These low-oxygen regions share many of the same causes, and they all have ecological and economic repercussions for ecosystems and people. Fortunately, we can pursue strategies to lessen the number, severity, and impacts of dead zones. The following list includes examples of factors that contribute to the development of dead zones (the cause), the consequences that result from dead zones, and possible solutions. Which of the following are consequences of dead zones?
a. Economic losses for fisher's
b. Death or aquatic organism that cannot escape
c. Policies to promote no-till agriculture
d. Construction of wetlands to absorb nutrients
e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition
Answer:
Answer:
e. Nutrient runoff from agriculture fertilizers, manure, and urban sources, which leads to rapid algal growth and subsequent bacterial decomposition
Answer:
Explanation:
Run off from agricultural wastes which contain Nitrogen and Phosphorus are the major sources causes dead zones.The process where these chemical get washed into the aquatic bodies is called Eutrophication.
These substances leads to algae boosts in the water.The increases population of the algae consumes the available oxygen in the water, therefore making the oxygen concentration drops or no oxygen at all;(Hypoxia)
As the algae population feed on the available resources in the water they exhausted this,and later die.
When the decomposing bacteria used the oxygen in the water to breakdown the dead algae they make use of the available oxygen.This further reduced the oxygen availability and therefore reduces the oxygen and hence the zone becomes the dead zone, because little or no oxygen is available for survival of organisms.
This is reversible if the process if europhication or other causes is eliminated

What amino acid residue would MOST likely be buried in the interior of a water-soluble globular protein?
The group of choices associated with the question is:
Tyr-Phe-Glu-Asn-Leu
Met-Phe-Pro-Ile-Leu
Val-Ala-Val-Glu-Val
Glu-Asn-Ser-Thr-Gln
Answer:
The correct answer is - Met-Phe-Pro-Ile-Leu
Explanation:
There is various type of amino acid residues that are located in the water-soluble globular protein, depend on the location inside the globular protein, that could be the center of the particular protein or interior of the protein.
Met-Phe-Pro-Ile-Leu is the amino acid residue among given options is the most likely the sequence as all the amino acids are nonpolar in this residue.
Thus, the correct answer is - Met-Phe-Pro-Ile-Leu
The amino acids that would be buried will be Met-Phe-Pro-Ile-Leu.
Amino acids simply refer to the organic compounds that contain amino and carboxylate functional groups. They're the molecules that combine in order to form proteins.
From the complete information, it should be noted that globular proteins are folded in such a way that their tertiary structure consists of hydrophilic, amino acids, arranged on the outside. From the options given, the amino acids that would be buried in the interior of a water-soluble globular protein will be Met-Phe-Pro-Ile-Leu.
