<span>Photosynthesis. Photosynthesis is a process whereby green plants and other organism like bacteria produce their food using organs like chlorophyll in plants and plasma membrane in bacteria to convert solar energy into chemical energy. The energy is stored in carbohydrate molecules, such as sugars, which are synthesized from carbon dioxide and water. Most plants, algae, and cyanobacteria perform photosynthesis. These organisms and plants produce organic waste product like water and Oxygen which is essentially for life on earth.</span>

Which structure of the nephron reabsorbs the most substances?
omeli [17]

Answer:

Proximal convoluted tubule

Explanation:

The major work of re-absorption is carried out in nephron by the proximal convoluted tubule (PCT). The PCT re-absorbs all the essential nutrients such as amino acid, potassium, glucose etc. and water driven by passive transfer based on concentration gradient. Along with gradient, pH of the urine also affects the re-absorption. Based on the pH of the urine (basic or acid), re-absorption of ionized acid increases or decreases.

2.Which of the following represents a genetic cross between 2 individuals that are each heterozygous for both traits?
wariber [46]

Answer:

A. AaBb x AaBb

Explanation:

The term heterozygous refers to the presence of two different alleles of same gene in an organism. The one allele can be of wild type (original type) and one can be mutated or newly formed.

In the question, two traits are represented by two letters, A and B and alleles as A and a and B and b, respectively. We are asked about a cross involving two traits and two individuals in such a way that both are heterozygous.

If we look at option A, AaBb x AaBb,

we see that one trait A and the other trait B is in heterozygous form (Aa and Bb) in both individuals.

If we look at option B. AABB x AABB

we see that one trait A and the other trait B is in homozygous form form (AA and BB) in both individuals. Homozygous means when the alleles are same for each trait in an individual.

If we look at option C,Aa x Bb

There are not two traits, one trait of one individual and other trait of other individual is being crossed that is not possible.

If we look at option D. AAaa x BBbb

Again, the individuals are homozygous for two traits.


Therefore, A is best option.


Hope it helps!

zhuklara [117]

Answer:

The correct answer is "is drained by an efferent arteriole".

Explanation:

The missing options of this question are:

A) has a basement membrane

B) is impermeable to most substances

C) is drained by an efferent arteriole

D) has a blood pressure much lower than other organ systems

The correct answer is option C) "is drained by an efferent arteriole".

The glomerulus are a network of small blood vessels that are specialized to function within the kidneys. The role of the glomerulus is to filter plasma and being one of the steps of water absorption in the kidneys. The glomerulus differs from other capillaries in the body in that it is drained by an efferent arteriole, which carry the blood that has already filtered by the glomerulus.
