Answer:
Photosynthesis is defined as the process in which the chlorophyll-containing plant
cells synthesise food in the form of carbohydrates, using carbon dioxide and water
in the presence of solar energy.
Sources of raw materials required for photosynthesis:
(a) Water is taken in from the roots of the plant and is transported to the leaves.
(b) Carbon dioxide from the air enters the leaves through the tiny pores called
stomata .
(c) Solar energy is absorbed by the chlorophyll pigment in the leaf. This energy is
used to synthesise (prepare) food from carbon dioxide and water.
Thus, photosynthesis can be represented by the following equation.

When looking at the cell membrane, where are the lipid heads located?
Answer:
The cell membrane consists of two adjacent layers of phospholipids, which form a bilayer. The fatty acid tails of phospholipids face inside, away from water, whereas the phosphate heads face the outward aqueous side.
The cell membrane consists of two adjacent layers of phospholipids, which form a bilayer. The fatty acid tails of phospholipids face inside, away from water, whereas the phosphate heads face the outward aqueous side.
What is cell membrane?
The cell membrane is a biological membrane that separates and protects the interior of all cells from the outside environment.
Moreover, the cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.
Hence, cellular membranes — including plasma membranes and internal membranes — are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains.

what are the three main particles of soil are? How do these shape and influence the type of soil we observe and its uses?
Answer:
Soil particles vary greatly in size, and soil scientists classify soil particles into sand, silt, and clay. Texture indicates the relative content of particles of various sizes, such as sand, silt and clay in the soil. Texture influences the ease with which soil can be worked, the amount of water and air it holds, and the rate at which water can enter and move through soil. Soil provides plants with foothold for their roots and holds the necessary nutrients for plants to grow; it filters the rainwater and regulates the discharge of excess rainwater, preventing flooding; it is capable of storing large amounts of organic carbon; it buffers against pollutants, thus protecting groundwater.
Female mosquitoes need a meal of blood from a person or other animal in order to produce eggs. It has been discovered that mosquitoes have cells on their antennae that can detect the insect repellent known as DEET. The repellent is not harmful to mosquitoes, but when mosquitoes detect DEET, they will not land on the surface where the DEET has been applied. This protects people from being bitten by mosquitoes. Recently, scientists found some mosquitoes that are resistant to DEET because they do not detect its presence. They bred these mosquitoes and eventually produced a population consisting of about 50% DEET- resistant insects. Identify the process most likely responsible for a mosquito initially becoming resistant to DEET.
Answer:
Mutation followed by natural selection made mosquitos resistant to DEET
Explanation:
Natural selection selects beneficial alleles, which increase their frequency in the population, resulting in adaptation. Aptitude, which is the contribution of each genotype to the next generation, increases too.
In many cases adaptations, resulting from the natural selection process can be correlated to environmental factors or selective pressures applied by other organisms or habitats.
Let us remember that, a mutation is a change or alteration in DNI sequences that introduce new variants. Many of these are eliminated, but some of them might succeed and be incorporated into each individual. These mutations are the ones that have been selected by natural selection.
So, in the exposed mosquitos´ example,
The selective pressure or modeling environmental factor is the DEET repellent.Some of the mosquitos mutated changing their behavior. The new mosquito´s response is not-detection of the repellent presence -only in those individuals carrying the mutations-. Natural selection benefits these mutations. Mosquitos survive and become more resistantProbably some of the mosquitos in the population suffered a mutation that favored them in not detecting repellent DEET. These individuals developed resistance to the chemical and were able to survive and reproduce, enhancing population sizes again. Natural selection benefited the mutation that gave them resistance.
Let us remember that the term resistance refers to an inheritable change in the population sensitivity, reflected through the consecutive failure of the chemical effects, correctly used in order to cause an effect on the insect population.
Repellents might produce a genetic modification in the insects, leading them to not detect the chemical. Insects evolve with the capability of tolerating the DEET dose that normally is used to repel mosquitos
The excessive use of DEET leads to the fixation of new genes -by natural selection- that result from mutations in the mosquito genetic material, which makes them become even more resistant to the chemical.

A 43-year-old Caucasian man with a 20-year history of bipolar disorder presents for the first time with long-term polyuria and polydipsia. He previously took lithium for mood stabilization for 15 years before initiating divalproex sodium therapy. He stopped using lithium because of the polyuria, but he felt that the polyuria never fully subsided. His weight is stable, and he has no other urinary complaints. His blood pressure is 115/80 mmHg and his physical exam is normal. His urinalysis shows no blood, cells, protein, glucose, nitrate, casts, or crystals.
What is the most likely cause of his polyuria?
1 Central diabetes insipidus
2 Nephrogenic diabetes insipidus
3 Polyuria secondary to hyperglycemia
4 Polyuria following acute kidney injury
5 Polyuria secondary to polydipsia
Answer:
The correct option is 2 Nephrogenic diabetes insipidus.
Explanation:
Nephrogenic diabetes insipidus (NDI) occurs when the renal tubule response to vasopressin (ADH) is weakened, resulting in the excretion of large volumes of dilute urine.
As the renal tubules do not respond to vasopressin (antidiuretic hormone) and are unable to reabsorb filtered water back into the body, the kidneys create a high volume of dilute urine in nephrogenic diabetes insipidus.
Nephrogenic diabetes insipidus (NDI) can be inherited or develop as a result of disorders that impede the ability of the kidneys to concentrate.
Therefore, the correct option is 2 Nephrogenic diabetes insipidus.
That is, the most likely cause of his polyuria is nephrogenic diabetes insipidus.

Which of the following suggests what happens when a mutation occurs in an organism? Select one:
Genes begin to appear in different individuals of the population all at once.
The organism develops new traits as a result of using a particular body part.
New traits appear from changes in the instructions given to the cell by the DNA. Useless traits are removed from the organism due to the loss of nucleotides
Answer:
New traits appear from changes to the DNA..
Explanation:
A mutation is when DNA is changed or altered in some way, causing it to tell the cells to do something different from what they usually do such as growing a body part a certain way, or making skin regenerate a certain way. some mutations are specific to one individual person or thing, other mutations are passed down through generations and become a new normal for the species. new diseases such as viruses are often caused by the virus mutating...this is how we have so many different strains of the flu...
