Answer:
here's your answer
Explanation:
the estimated maximum energy efficiency of photosynthesis is the energy stored per mole of oxygen evolved, 117/450, or 26 percent.
Consequently, plants can at best absorb only about 34 percent of the incident sunlight. The actual percentage of solar energy stored by plants is much less than the maximum energy efficiency of photosynthesis. An agricultural crop in which the biomass (total dry weight) stores as much as 1 percent of total solar energy received on an annual areawide basis is exceptional, although a few cases of higher yields (perhaps as much as 3.5 percent in sugarcane) have been reported. There are several reasons for this difference between the predicted maximum efficiency of photosynthesis and the actual energy stored in biomass. First, more than half of the incident sunlight is composed of wavelengths too long to be absorbed, and some of the remainder is reflected or lost to the leaves
What is the end result of mitosis?
A) one cell with two identical copies of DNA
B) two cells with different copies of DNA
C) one cell with two different copies of DNA
Answer:
A) one cell with two identical copies of DNA
Explanation:
The end result of mitosis is one cell with two identical copies of DNA.
Answer: A) one cell with two identical copies of DNA
Explanation: Mitosis is a process of cell division that occurs in somatic cells (non-reproductive cells). It involves a series of steps that result in the formation of two identical daughter cells.
During mitosis, the parent cell undergoes several stages: prophase, metaphase, anaphase, and telophase. In prophase, the DNA condenses into visible chromosomes, and the nuclear membrane begins to break down. In metaphase, the chromosomes align in the middle of the cell. In anaphase, the sister chromatids separate and move towards opposite poles of the cell. Finally, in telophase, the nuclear membranes reform around each set of chromosomes, and the cell begins to divide.
At the end of mitosis, each daughter cell contains the same number and type of chromosomes as the parent cell. This means that each daughter cell has an identical copy of the parent cell's DNA. The division of the cytoplasm then occurs in a process called cytokinesis, resulting in two separate daughter cells.

Explained the effects of the use of antibodies in the control of a disease
Answer:
An antibody, also known as an immunoglobulin, is a large Y-shaped protein produced by B- cells and used by the immune system to identify and neutralize foreign objects such as bacteria and viruses.
Each tip of the “Y” of an antibody contains a paratope (a structure analogous to a lock) that is specific for one particular epitope (similarly analogous to a key) on an antigen, allowing these two structures to bind together with precision.
Though the general structure of antibodies is very similar, a small region at the tip of the protein is extremely variable, allowing millions of antibodies with different antigen binding sites to exist. This region is known as the hypervariable region.
Five isotypes of antibodies are found in different locations and perform different specific functions.
The base of the Y plays a role in modulating immune cell activity. This region is called the Fc region, and phagocytes may bind to it to initiate phagocytosis.
Antibodies that bind to surface antigens on a bacterium attract the first component of the complement cascade with their Fc region and initiate activation of the classical complement system.
Polio viruses contain DNA. The viruses in the polio vaccine have DNA in which the base sequence has several differences from the base sequence in the normal polio virus. Suggest how this makes them unable to reproduce in the human body.
Answer:
The polio strains cannot reproduce because they are weakened.

Why are gametes the only haploid cells in your body?
Gametes are the only haploid cells in the human body because they are the cells involved in sexual reproduction, which requires the combination of one set of chromosomes from each parent to form a new individual. The rest of the cells in the human body are diploid and do not participate in sexual reproduction.
Gametes, which are also known as sex cells, are the only haploid cells in the human body because they are the cells that are involved in sexual reproduction. Haploid cells have a single set of chromosomes, while diploid cells, which make up the majority of cells in the human body, have two sets of chromosomes.
During sexual reproduction, gametes from each parent combine to form a new individual. The gametes from each parent contribute one set of chromosomes to the offspring, so that the resulting diploid cells in the offspring have two sets of chromosomes, one set from each parent.

Answer:
Human gametes are haploid (n) as they are formed by meiosis during the process of gametogenesis.
Explanation:
Haploid can be described as a cell that contains a single set of chromosomes. The term haploid can also refer to the number of chromosomes in egg or sperm cells.
Haploid gametes lead to the fusion of male and female gametes, by which a diploid zygote is formed and the number of chromosomes remains the same in the progeny.
In humans, gametes are haploid cells that contain 23 chromosomes.

2. Coastlines are continually eroded by what
process? sc.6.E.6.2
A longshore currents
B parallel shore currents
C shortshore currents
D perpendicular shore currents
???????????
Coastlines are continually eroded by longshore currents, which are currents that flow parallel to the shoreline. These currents can be caused by the wind and waves, and they can transport sediment (such as sand and gravel) along the coast. As the sediment is moved and deposited, it can cause the coastline to change shape and erode over time.
Answer:
Explanation:
Coastlines are continually eroded by longshore currents.
Longshore currents are ocean currents that flow parallel to the shoreline. They are created when waves approach the shore at an angle, and the water is deflected by the friction of the bottom and the shape of the coastline. The resulting current flows parallel to the shore, and can cause erosion of the coastline over time.
Parallel shore currents and shortshore currents are not correct terms. Perpendicular shore currents are not a natural phenomenon and do not occur in the real world.

Dimethylmercury is non polar volatile liquid that is lethal to animals. It’s structure is CH3-Hg-CH3. Predict the mechanism and timeframe of passage into cells for dimethylmercury based upon its chemical properties.
The dimetylmercury is a fat soluble compound thus it can pass into the cells easily through the lipid bi layer.
How does the compound work?We know that the compounds that are water soluble would have to be ionic. It is very vital that we start the discussion from here because we ought to know that the compounds that are covalent would not be found to dissolve in water.
On the other hand, we have to recall that the entrance of the cell is a nonpolar region as that area is mostly filled with the fats that we can find around there. It then means that the compounds that may be able to pass into the cell very freely has to be the compounds that are fat soluble based on its chemical properties.
We must recall that Dimethylmercury is non polar volatile and as such it can be able to pass through the membrane and enter into the cells.
