Why is there so little life at the bottom of the ocean?
Answer:
Lack of sunlight means no algae or plants to support the food chain, so food is scarce. Deep-sea animals must survive on the decaying scraps of dead organisms from the upper layers of the ocean, which sink to the bottom.
DNA is bound into this shape for storage and replication before mitosis.
chromosomes
Triangles
Circles
Ovals
Answer:
chromosomes
Explanation:
Deoxyribonucleic acid, also known as, DNA, is the genetic material in living cells that stores genetic information. However, DNA is supercoiled around certain proteins called HISTONES into an X-shaped threadlike structure called CHROMOSOMES.
Chromosomes are the forms in which DNA is stored and undergoes replication in the nucleus (eukaryotic cells) or nucleoid (prokaryotic cells).
The chemical bond between amino acids is called a bond.
Answer:
Amino Acids Are Linked by Peptide Bonds to Form Polypeptide Chains. Proteins are linear polymers formed by linking the α-carboxyl group of one amino acid to the α-amino group of another amino acid with a peptide bond (also called an amide bond).
The chemical bond between amino acids is called a peptide bonds.
A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction (also known as a condensation reaction) and usually occurs between amino acids.
Within a protein, multiple amino acids are linked together by peptide bonds, thereby forming a long chain. Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of neighboring amino acids.

Whatstatement accurately names and describes the function of the organelle labeled B?
The correct answer is Option A .
Organelle B = Mitochondrion.
A mitochondrion converts food into energy for cellular functions.
Explain functions of mitochondrion?According to the diagram, the organelle labelled A absorbs solar light energy and transfers it to the mitochondria ( organelle labelled B )The energy that the mitochondrion receives is put to use by the organelle to break down the food that has been consumed and produce the energy (ATP) that powers every other cell.Thus, we can deduce that the statement "A mitochondrion produces energy from food to power cellular processes" accurately describes the function of organelle B.Oxidative phosphorylation, which produces ATP using the energy released during the oxidation of the food we eat, is the traditional function of mitochondria. For the majority of biochemical and physiological processes, including growth, movement, and homeostasis, ATP is used as the main energy source in turn.To learn more about mitochondrion refer to :

match each part of a virus with the best description of it.
Answer:
Envelope protein - proteins that stick out from the virus body
Envelope - protein shell around the virus
DNA/RNA - instructions to make more viruses
Capsid - container holding the DNA/RNA
Capsomeres - building blocks of the capsomeres
Explanation:
The envelope is the outermost layer of the virus. Envelope proteins are attached to the envelope and stick out. These are the proteins that bind to cell receptors to allow viruses to enter cells.
The capsid is made up of capsomeres, and it surrounds the genome of the virus. The genome is either made up of DNA or RNA, and contains instructions to make more viral particles.
A group of scientists predicts that Earth’s oceans will be able to take up more carbon dioxide as atmospheric carbon dioxide levels increase and the atmosphere warms. Which of these statements about the solubility of gases in ocean water would lead you to question this prediction?
a Solubility decreases with an increase in salinity.
b Solubility decreases with an increase in salinity.
c Solubility decreases with an increase in temperature.
d Solubility decreases with an increase in temperature.
Answer:
b
Explanation:
The solubility of gases in the ocean water should result into decrease in solubility that increases salinity.
What is the solubility of gases?The solubility of a gas should be in the liquid and that should be directly proportional with respect to the partial pressure that should be presented above the surface of the liquid.
Here the henry law should be applied that represent the partial pressure that above the solution also it should be proportional to the fraction of the mole of the gas.
Therefore, the option b is correct.

58. What do you think would happen if a cell were treated internally with reagents that blocked the formation of clathrin coated vesicles
Answer:
Molecules or proteins will not be transported within the cells from organelles to organelles
Explanation:
If a cell were treated internally with reagents that blocked the formation of clathrin coated vesicles, proteins will not be transported within the cell from one organelles to another because clathrin is a protein that lead to the formation of coated vessicles and these coated vessicles play a major role in vessicular transport by allowing the transport of proteins or molecules with the cells from organelles to organelles like organelles in the post-Golgi network connecting the trans-Golgi network endosomes and also cell membrane and lysosomes.

The vulva is the external part of the female genital organs.
What is offspring grows?"Offspring grows" is a phrase commonly used to refer to the development of a fetus during pregnancy.
It means that the embryo, which is the early stage of development of the fertilized egg, undergoes a series of cellular divisions and differentiation processes, eventually forming a fully-formed baby.
The growth of the offspring is a complex and highly regulated process that involves many different biological systems and processes, including the placenta, umbilical cord, and various hormones and signaling molecules.
The growth and development of the offspring is a critical aspect of reproduction, and is essential for the continuation of the species.

Explanation:
Jon always keeps his bread in the cabinet, in the dark. Recently, his bread has been getting moldy rather quickly and needed to be thrown out. For an experiment, Jon puts two slices of the same brand of bread in the cabinet, in the fridge, in the sunlight (on the counter), and in the freezer. Jon leaves the bread in there for two months and checks it once every day. At the end of his experiment, Jon will look at all his data and compare to see which method keeps his bread fresh the longest.

Answer:
IV: Method of preserving bread
DV: How long the bread stays fresh
Control: Bread kept in the cabinet
Constant: Same slice of bread, same brand of bread, same amount of time
Data Type: Quantitative
Explanation:
Independent variable is the variable that is manipulated or changed by the experimenter in an experiment. In this case, the independent variable is METHOD of PRESERVING BREAD or LOCATION OF KEEPING BREAD.
Dependent variable is the variable that is being measured in the experiment. The dependent variable responds to the changes made to the independent variable. In this case, How long the bread stays fresh is the dependent variable.
Constants are variables that the experimenter intentionally keeps unchanged throughout the experiment in order not to influence the result. In this experiment, the constants are: Same slice of bread (2 slices), same brand of bread, same amount of time (2 months).
Control group is the group that does not receive experimental treatment. The control group of this experiment will be the BREAD HE KEEPS IN THE CABINET.
Data type can either be quantitative or qualitative. The data type in this experiment is QUANTITATIVE because it involves the use of counts and numbers, which is time in this case.

g Define nitrogen balance and describe how it is used to assess protein requirements in humans. Give examples of positive, zero (equilibrium), and negative nitrogen balance in humans.
Answer:
The nitrogen balance refers to the ingested nitrogen, one gram of nitrogen is equivalent to 6.25 g approx of protein.
Nitrogen in our body must be in balance, for that a large part is eliminated in urine, in the form of urea, and the rest through sweating, breathing and in epithelial expressions.
Explanation:
The nitrogen balance if it has a positive value is because we lose less than what we ingest in the day, if its value is zero, it is because the same thing that we ingest is we lose it in the day.
Instead, the problem is usually when the value is negative, here we are talking about the organism releasing more than we ingest, therefore some systemic failure will be happening.

Can you guys help me with this?
Answer:
The law of segregation states that genes have alternative forms, or alleles. In a diploid organism, the two alleles of a gene separate during meiosis and gamete formation; each sperm or egg carries only one allele of each pair. This law explains the 3:1 ratio of the F2 phenotype observed when monohybrids self-pollinate. Each organism inherits one allele for each gene from the parent. In heterozygous individuals, the two alleles are different, and expression of the dominant allele masks the phenotypic effect of the recessive allele. In hom0zygous individuals, the two alleles are identical.
The law of independent assortment states that the pair of alleles for a given gene segregates into gametes independently of the pair of alleles for any other gene. This law explains the 9:3:3:1 ratio of the F2 phenotypes in a cross between dihybrids.
Explanation:
The law of segregation explains that, during gamete formation, each gamete receives just one copy of the gene (allele) which is random. Therefore, if we have two heterozygotes (Aa), the possible genotypes are AA, aa, Aa and Aa. Therefore, the ratio of the dominant phenotype to the recessive is 3:1.
The law of independent assortment explains that the alleles of different genes are inherited independently of one another. That explains the 9:3:3:1 phenotype ratio when crossing two individuals heterozygous at two different genes

The large object in the picture above is a single bacteria cell. The many small structures attached to it are viruses called
bacteriophages which are attaching to the receptor sites on the bacteria cell. Which of the following is one important
difference between a virus and a bacteria cell?
Answer Options:
a. a virus is much larger in size than a bacterial cell
b. a virus always causes more severe disease than a bacterial cell
c. a virus can never reproduce on its own, but a bacterial cell can
d. a virus does not contain genetic material, but a bacterial cell does
Answer:
c. a virus can never reproduce on its own, but a bacterial cell can
Explanation:
A virus is not cellular, and is significantly smaller than bacterial cells. Because they aren't cellular, to reproduce, viruses have to infect other cells. Inside the cell, they hijack the cell's machinery to allow their genome to be replicated and new viral particles to form. This is how viruses reproduce. Bacteria reproduce by asexual reproduction.
