What is the highest total blood cholesterol concentration (mg/dL) that falls within the desirable range
Cholesterol levels below 200 mg/dl are considered "desirable blood cholesterol," 200 to 239 mg/dl are considered "borderline-high blood cholesterol," and 240 mg/dl and above are considered "high blood cholesterol."
There are two forms of cholesterol: low-density lipoprotein (LDL) and high-density lipoprotein. Cholesterol is a waxy, fatty molecule (HDL).The "bad" cholesterol LDL, or too much of it, can accumulate in blood arteries and form plaques, which are fatty deposits.Heart attacks and strokes are only two more issues that these plaques can cause.Low levels of both total and LDL cholesterol are ideal. However, having higher levels of HDL, or "good," cholesterol, may lower your chance of having a heart attack or stroke.Doctors can check your total cholesterol, HDL, and LDL levels.learn more about Cholesterol levels here: https://brainly.com/question/841110

Mitosis is a type of cell division. Organize the images below to show the steps of mitosis.
The image in the correct order in which mitosis will occur will be 3, 4, 2, and 1.
What is mitosis?It is the division of vegetative cells that results in the formation of 2 daughter cells.
There are 4 stages of mitosis - prophase, metaphase, anaphase, and telophase. Thereafter, the cytoplasm divides in a process known as cytokinesis.
At prophase, the nuclear membrane dissolves and the chromatin material condenses.
At metaphase, the chromosomes align at the center of the cell while the spindle fiber engages each of them from the opposite ends of the cell.
At anaphase, chromosomes are pulled apart and sister chromatids of the same chromosome begin migrating towards opposite ends of the cell.
At telophase, migration of chomatids complete.
Thereafter, the nuclear membrane reappears around each chromosome, the chromosomes decondense, and the cytoplasm divides to give two independent cells.

Atp energizes other molecules in cells by transferring a(n) ________ to those molecules.
ATP energizes other molecules in cells by transferring phosphate groups to those molecules.
An energy-demanding process can be coupled to ATP hydrolysis in a cell in one of two ways: either ATP is used to activate a reactant, or ATP is used to alter a reactant's form. Transferring a phosphate group to the reactant results in the phosphorylation of the product, which can be used to accomplish either goal.
Cells can use chemical energy known as ATP, or adenosine triphosphate. It is the molecule that gives your cells the power to accomplish things like contract your muscles as you walk down the street.

Stomach acidity is in the range of ph 1 to 2. How might this inhibit the growth of ingested bacteria?
Stomach acidity is in the range of pH 1 to 2 because of the presence of hydrochloric acid (HCL) and pepsin.
Cells in the stomach are responsible for the secretion of HCL in the stomach lumen.For the clearance of ingested bacteria, a particular range of pH is required. HCl and pepsin present in the gastric lumen can kill the bacteria within 15 min if the pH of the lumen gets maintained below 3. If the pH of the lumen increased by 4, it can cause bacterial overgrowth and the establishment of infection.

If an organism with the genotype aabb produces gametes, what proportion of the gametes would be bb?
Assuming independent genes and normal meiotic events, the gametes of an individual with genotype aabb are ab, ab, ab, ab. There are no bb gametes. The answer is NONE.
What is a gamete?
A gamete is a haploid cell that results from the meiotic division of germ cells during gametogenesis.
These haploid cells have half the number of chromosomes of somatic and germ cells, and their destiny is to merge with another gamete to produce a new diploid cell.
During gamete formation, homologous chromosomes separate after crossing over, and finally, sister chromatids separate too, resulting in four haploid cells, each of them with a different allele combination.
When genes are in different chromosomes or far from each other in the same chromosome, they express independent assortment during meiosis. These genes are independent.
Independent assortment means that during a meiotic event, alleles from two or more different genes distribute in gametes independently from each other.
Each gamete receives an allele of a gene that does not depend on nor influence the allele of another gene in the same gamete.
In the exposed example, the homozygous recessive genotype is composed of two diallelic genes ⇒ aabb
Genotype: aabbAllele combination ⇒ Gametes ⇒ ab, ab, ab, ab
Assuming independent genes, unless there is some sort of problem during meiosis, there are no gametes bb, because gametes result from the combination of both genes.

Answer:
Fiber helps to prevent constipation in the human digestive system.
Explanation:
According to nutritionists fiber is very important in digestion as it increases the amount of stool , hence prompting for deification which generally reduces the amount of time waste stays in the small intestines .
Another reason is that it gets in touch with the schist that has been rejected or is of no value to the system and binds it to make it compact waste hence it is easier to move along the small intestine and the colon .
Finally it facilitates movement and exercise of the bowel , by prompting regular movement .
a short sequence of DNA is replicated using a mixture of dideoxynucleotide triphosphates, which lack a hydroxyl group at the 3' location. The new strands are separated from the old DNA
Sanger sequencing mimics the natural process of DNA replication by using dummy nucleotides to stop replication whenever a specific nucleotide is encountered. Because this truncated replication happens repeatedly, nucleic acids of various lengths accumulate and can be used to determine the position of each nucleotide in the sequence
ddNTPs are included (dideoxynucleoted)
A representation of 16 nucleotides arranged in a single horizontal strand of DNA is shown. Horizontal cylinders represent the deoxyribose sugar molecule and vertical rectangles represent the nitrogenous base in each nucleotide. The deoxyribose sugar and nitrogenous base of a single DNA strand are shown in grey. Below the single strand are four DDNTPs and four individual nucleotides. Sugar molecules are black in the bottom four DDNTPs in the bottom four individual nucleotides. To represent the bases' chemical identities, the nitrogenous bases on the DDNTPs and the lower four nucleotides are colored differently: DDATP is green, DDCTP is orange, DDTTP is red, and DDGTP is blue.

Consider a hypothetical food chain consisting of grass, rabbits, and foxes. The primary productivity of the grass is 200 units. What is the maximum amount of energy that we should expect to be
The maximum amount of energy that we should expect to be recycled from fox trophic level back to the grass trophic level is 0 units.
A food chain describes who eats whom in the wild. Every living thing – from unicellular algae to giant blue whales – needs food to survive. Every food chain is a possible pathway that energy and nutrients can travel through an ecosystem. The primary productivity of the grass is 200 units. There is a 10 fold decrease in the amount of energy units as we move upwards in production chain. So from grass to rabbits we lose energy. The foxes will only really have two units once it's decreased by 10 fold again. The grass does not get any energy from the decaying bodies of foxes, they get the minerals that they need to grow. And so the correct answer to this question is 0 units because when the energy gets recycled from fox trophic level back to the grass trophic level it will be totally reduced.
Note: The question seems to be incomplete. So the complete question is "Consider a hypothetical food chain consisting of grass, rabbits, and foxes. The primary productivity of the grass is 200 units.

What does the telomere do in the body?A chromosome's end contains a stretch of repeating DNA sequences known as a telomere. Chromosome ends are shielded from fraying or tangling by telomeres. The telomeres get a little bit shorter every time a cell divides. They eventually get so short that the cell can no longer successfully divide, and the cell then perishes.
With age, telomere length decreases.
