Explanation:
A team of deep-sea divers and biologists is exploring the open ocean. As team members dive downward from the surface, they observe significant changes to the ocean community at a depth of about 200 meters. What is the main cause of the changes at this depth?
A. loss of brightness of the water
B. increasing salinity of the water
C. increasing temperature of the water
D. decreased oxygen concentration of water
Answer:
A
Explanation:
sunlight is the main change. sun light cannot penetrate into the deep layers of the ocean and availability of oxygen is also low there. this causes the considerable amount of organisms to live in the upper layers of the ocean and we can only observe decomposing organisms in the deeper layers!

how many copies of each chromosome are contained in each of the daughter cells resulting from meiosis?
Answer:
Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move in to the third and final phase of meiosis: meiosis II. At the end of meiosis I there are two haploid cells.
Explanation:
Hope this helps.
Each daughter cell has 23 of the 46 chromosomes. Sister chromatids make up each chromosome. Daughter cells enter meiosis II, the final step. Two haploid cells result from meiosis I.
What is meiosis?Meiosis is a specialized kind of cell division that occurs in the germ cells of animals that reproduce sexually. This form of cell division is responsible for the production of gametes, such as sperm and egg cells. This process requires two rounds of cell division, and at the end of it, there are four cells that each have a single copy of each chromosome.
There are 46 chromosomes total, and each daughter cell has 23 of them. Each chromosome is composed of two sister chromatids. In the second and last stage of meiosis, daughter cells participate. Meiosis I always results in the formation of two haploid cells.

If an experiment was being conducted using an enzyme that was very sensitive to changes in pH (which could result in denaturation), what should be added to the experiment to prevent the enzyme from denaturing?
A. a buffering solution
B. extra substrate
C. an acid
D. a base
Answer:
maybe the answer is C..sorry if i wrong
If an experiment was being conducted using an enzyme that was very sensitive to changes in pH, a buffering solution must be added in order to prevent the enzyme from denaturing. Thus, the correct option for this question is A.
What is the denaturation of an enzyme?The denaturation of an enzyme may be defined as a process through which a molecular structure of an enzyme gets deviate from its original state due to exposure to high temperature, pH sensitivity, etc.
The function of a buffering solution is to stabilize the pH of the given solution. It helps the other component of the solution to resist in response to pH change. A Buffer solution is capable to neutralize the effect of the small amount of acid or base.
Therefore, a buffering solution must be added in order to prevent the enzyme from denaturation. Thus, the correct option for this question is A.

Explanation:
During one year, the birthrate in a country is 28 births per 1000 people, and the death rate is six deaths per 1000 people. What is the population growth rate?
Answer: 22
Explanation: 28/1000-6/1000=22/1000
Birth rate is the births per 1000 people which is subtracted by the death rate which is the deaths per 1000 people, this phenomenon is known as Population growth rate. So, 22/1000 is the population growth rate for this.
What is Birth Rate?Birth rate is the total number of people born per year per 1000 in the population. Birth rate is also known as Natality.
For example, if 65 births occur per year per 1000 individuals, the birth rate is 65. If it is expressed in the percentage, it is 6.5 per 100 or 65%.
Population is divided into many parts like Juveniles (Period before puberty), adults and Post reproductive adults. Birth rate is higher than the death rate as the population is younger, the faster that population grows.
When the birth rate is expressed as per the age group, this is called the standardized birth rate. Birth Rate is determined by the ratio between the number of live births in a population during a year and total mid-year population for the same year multiplied by 1000.
Thus, birth rate is the births per 1000 people which is subtracted by the death rate which is the deaths per 1000 people, this phenomenon is known as Population growth rate. So, 22/1000 is the population growth rate for this.

Explanation:
Uh that's what the skeleton is made out of. Nothing I can really explain
Answer:
Tissue that gives strength and structure to bones. Bone is made up of compact tissue (the hard, outer layer) and cancellous tissue (the spongy, inner layer that contains red marrow). Bone tissue is maintained by bone-forming cells called osteoblasts and cells that break down bone called osteoclasts. Bones also contain blood vessels, nerves, proteins, vitamins, and minerals. Also called osseous tissue.
A quick anatomy of the bone! (extras)
Anatomy of the bone. The bone is made up of compact bone, spongy bone, and bone marrow. Compact bone makes up the outer layer of the bone. Spongy bone is found mostly at the ends of bones and contains red marrow. Bone marrow is found in the center of most bones and has many blood vessels. There are two types of bone marrow: red and yellow. Red marrow contains blood stem cells that can become red blood cells, white blood cells, or platelets. Yellow marrow is made mostly of fat.

Describe how bacteria are used to produce enzymes for washing powders.
Answer:
By using genetic engineering to insert the gene for the desired enzyme into the bacterial chromosome, then growing large amounts of the modified bacteria in fermenters.
Explanation:
Answer:
Bacteria such as fungi or algae are inserted in fermenter and feedstock such as glucose, amino acid, sucrose are inserted to be a source of food for them.
Then they are left for a time for the bacteria to reproduce more and to produce more enzymes in their cells, Then if the enzymes are extracellular they are extracted directly from the filtrate, if they are intercellular they are separated from the feedstock and crushed to be separated with any solvent such as water.

what cells release histamine during allergic responses
Answer:
Histamine is a substance that is released by the body during an allergic reaction. Mast cells, which are a type of white blood cell, release the histamine, and this triggers a process which is most commonly referred to as the “inflammatory immune reaction”.

Because one original strand of the double-stranded helix is found in each daughter molecule, the replication process is called semiconservative.
Replication is the process by which a DNA molecule generates two identical to itself, and is key in cell reproduction.
All cells in the body must have the exact same genome (as in asexual reproductive organisms, which are practically clones of each other) and this is achieved through replication.
The process consists of separating the two strands of DNA, each of which will function as a template to synthesize a new one.
That is, each of the two strands of DNA serves as a template to synthesize a new complementary strand of the template.
In the end, two DNA molecules are formed, each of the two DNA molecules has a new chain and one original strand, this mode of replication is called semi-conservative.
Therefore, we can conclude that because one original strand of the double-stranded helix is found in each daughter molecule, the replication process is called semiconservative.
