because each old strand of the parent molecule serves as a(n) ____________ for and is present in each new daughter strand, the process of dna replication can be described as ____________ .
Answer:
The process of DNA replication can be summarized as follows: DNA unwinds at the origin of replication. Helicase opens up the DNA-forming replication forks; these are extended in both directions. Single-strand binding proteins coat the DNA around the replication fork to prevent rewinding of the DNA. Hope this helps you with the question young lad

In humans, the presence of freckles (F) is dominant to the absence of freckles (f).
Two heterozygous individuals mate.
What are the genotypes of the two individuals?
What is the probability of them having a child with freckles?.
Since the two individuals are heterozygous, the genotypes they will have for freckles will be Ff for each. The probability of having a child with freckles will be 75%.
Heterozygous refers to the presence of two different forms of the allele for a trait. These two different alleles are actually the contrasting forms of a gene. For example, the trait height can have two contrasting alleles one for tall and one for dwarf.
Genotype refers to the genetic make-up or constitution of an organism. This genetic constitution can be for the entire genome or for any particular trait. The genotype also provides insight about the allelic combinations.

The body fluid of sharks has a much lower concentration of sodium chloride than that of the surrounding seawater, and sharks are able to remain in osmotic equilibrium with the external environment. How can this be the case?
The body fluid of sharks has a much lower concentration of sodium chloride than that of the surrounding seawater, and sharks are able to remain in osmotic equilibrium with the external environment. Sharks store enough urea to match the total solute concentration of the surrounding seawater
An osmoconformer's internal bodily fluids are best described as having about the same total solute concentration as the surrounding environment. The sharks may use their amazing capacity to absorb ammonia to increase their urea reserves. The fish, which are scavengers, frequently go extended periods without eating, depriving themselves of the raw protein source necessary to keep their tissues' urea levels at a healthy level.

Beginning with the flow phase, arrange the biochemical processes in the order in which they occur during the menstrual cycle.
FSH and LH stimulate the follicles to develop and the oocyte to produce estrogen.
A breakdown of corpus luteum causes progesterone levels to drop.
A spike in LH causes the follicle to rupture.
The endometrial lining breaks down and low levels of estrogen stimulate the pituitary to release FSH and LH.
Rising estrogen levels suppress FSH production and development of other follicles.
High progesterone levels maintain the endometrial lining of the uterus.
The menstrual cycle begins with a change in hormonal level and maintaining the endometrial lining of the uterus.
How does hormone level change during the menstrual cycle?The endometrial lining is a breakdown, and low levels of estrogen cause to stimulate the pituitary to release FSH and LH, this hormone stimulateing follicles for developing oocytes to produce estrogen.
When estrogen level is at a peak, suppresses FSH production and develops other follicles, a gradual increase in LH causes the follicle to rupture then high progesterone levels maintain the endometrial lining.

Answer:
How does mutation affect cell cycle? In most instances, the alteration of the DNA sequence will result in a less functional (or non-functional) protein. The result is detrimental to the cell and will likely prevent the cell from completing the cell cycle; however, the organism is not harmed because the mutation will not be carried forward.

How has the flow of carbon changed between the atmosphere and the ocean?
The flow of carbon between the atmosphere and the ocean changed in the following ways-
The concept sounded straightforward enough: the oceans would absorb more carbon dioxide the more it was released into the atmosphere by burning fossil fuels. The ocean would keep soaking up more and more carbon dioxide until ocean warming caused ocean circulation to shut down. When the water trapped at the surface became saturated, the ocean's uptake of carbon would slow down.
The ocean, however, also contributes to the slightly faster carbon cycle. Carbon dioxide gas dissolves in and ventilates out of the ocean in a constant exchange with the atmosphere at the surface, where air meets water. As soon as carbon dioxide enters the ocean, it combines with water molecules to release hydrogen, increasing the ocean's acidity. Bicarbonate ions are created when the hydrogen reacts with the carbonate left over from rock weathering.
Prior to the industrial revolution, the ocean released carbon dioxide into the atmosphere in an equal amount to the carbon it absorbed from rock weathering. The ocean now removes more carbon from the atmosphere than it produces, however, as a result of rising atmospheric carbon concentrations. The ocean will eventually absorb up to 85% of the excess carbon that mankind have added to the atmosphere by burning fossil fuels, but because the process depends on the passage of water from the ocean's surface to its depths, it will take millennia to complete.
The rate at which the ocean removes carbon dioxide from the atmosphere is in the meantime governed by winds, currents, and temperature. Over the few thousand years between the ice ages, it is likely that variations in ocean temperatures and currents helped take carbon from and subsequently restore carbon to the atmosphere.

In the following map, the highest recombination is seen between the E and G genes. They have the highest gene distance between them, which is 12 map units. The last option is the correct answer.
What is a recombination?Recombination between two genes takes place when there is enough distance between them for the genes to cross over. More is the distance, more is the chance, and less is the distance, less is the chance. When two genes are close to each other and don't allow crossing over, they are called "completely linked gene". Due to recombination, the variation is seen in the offspring. The crossing takes place during the pachytene stage of prophase I of meiosis.
Hence, the correct answer is the last option, as the maximum distance between E and G is seen, which is 12 map units.

Glucose-6-Phosphate is Needed to Generate Dihydroxyacetone Phosphate.
Inorganic Phosphate is Needed to Generate Dihydroxyacetone Phosphate.
None of the Statements are Correct.
All Correct Statements Pertaining to the Dihydroxyacetone Phosphate Reaction Step in Glycolysis
Conversion of dihydroxyacetone phosphate in glycolysis requires glucose-6-phosphate to generate dihydroxyacetone phosphate. So the correct option is C.
What is glycolysis?Glycolysis is the process of forming pyruvate from the catabolism of glucose molecules. This process creates ATP, NADP, and FADH₂ molecules. The dihydroxyacetone phosphate (DHAP) reaction step involves the conversion of DHAP to glyceraldehyde-3-phosphate (G3P) by the enzyme triose phosphate isomerase. This enzyme catalyzes the isomerization of a tri-carbon sugar to another tri-carbon sugar (G3P).
Dihydroxyacetone phosphate is in the glycolytic pathway and, along with glyceraldehyde-3-phosphate, is one of two products formed when fructose-1,6-bisphosphate is broken down. It is readily and reversibly isomerized to glyceraldehyde-3-phosphate.

O organisms that spend their larval or juvenile stage as plankton
O organisms that are holoplankton
Oorganisms that are phytoplankton
Organisms that are holoplankton. Meroplankton are a diverse group of aquatic organisms with life cycles that include both planktonic and benthic stages.
The larval stages of bigger organisms make up a major portion of the meroplankton. Holoplankton, which are planktonic organisms that remain in the pelagic zone as plankton during their entire life cycle, can be compared with meroplankton.
Many meroplankton go on to the nekton or adopt a benthic (typically sessile) existence on the bottom after spending some time in the plankton. Benthic invertebrate larval stages make up a large component of planktonic populations. For many benthic invertebrates, the planktonic larval stage is very important for the dispersal of their young.
