The researcher in the virtual lab was using waste from a fish farm to provide nutrients for the algae. Algal growth utilizes carbon-di-oxide (CO₂) and converts it into useful byproducts thereby reducing CO₂ levels in the environment.

Feeding algae with the waste from the fish farm would enhance algal growth. Algae come under the group of organisms that are capable of performing photosynthesis.

Algae utilize CO₂ from the environment for photosynthesis and convert it into biomass and oxygen (O₂). This biomass produced can be used as an eco-friendly source of biofuel in the city.

Therefore, algae growth is utilized to trap CO₂ and replace it with O₂ in the environment.

The product of the light-dependent reactions of photosynthesis is used to generate ATP

The chloroplasts' thylakoid membrane experiences a light reaction. Both cyclic and noncyclic photophosphorylation is involved. During the photochemical phase of photosynthesis, photophosphorylation is the process of producing ATP from ADP and H3PO4 in the presence of light and chlorophyll-a.

ATP is created during cyclic photophosphorylation, and ATP and NADPH2 are produced during non-cyclic photophosphorylation. As water is photolyzed, oxygen is also created.

Therefore, ATP, NADPH2, and O2 are the byproducts of the light process.
By releasing its phosphate groups, the coenzyme ATP helps enzymes like ATP triphosphatase transmit energy to cells.
Therefore, ATP is frequently referred to as the "energy currency of the cell" by biologists. From a biological standpoint, ATP is made up of three parts.

When carbohydrate supplies are depleted in cells, amino acids from proteins can enter aerobic respiration after nitrogen is removed from the amino acids and excreted.

Before proteins from food can be utilized by your cells, your body must first break them down into amino acids.

Some amino acids will be broken down for energy through cellular respiration if there are more amino acids than the body requires or if cells are starved.

Amino acids must first have their amino group removed in order to enter cellular respiration.

As a waste product from this process, ammonia is produced. In mammals like humans, the ammonia is transformed to urea and eliminated from the body through urine.

Different amino acids enter the cellular respiration pathways at various stages after being deaminated.

Water is the nutrient that transports, dissolves, and reacts with chemicals; provides lubrication and shock protection; and aids in temperature regulation.

Water is a substance (of molecular formula H₂O) found at room temperature and pressure as a clear liquid.

It is present naturally as rain, and found in rivers, lakes and seas; its solid form is ice and its gaseous form is steam.

However, water is a major requirement by living organisms as it plays several pivotal roles in the body.

Water as a nutrient helps in the transportation dissolution and reaction with chemicals. It provides lubrication and shock protection; and aids in temperature regulation.

The water in the body has an important role as a thermoregulator, regulating the overall body temperature by helping dissipate heat. If the body becomes too hot, water is lost through sweat and the evaporation of this sweat from the skin surface removes heat from the body.

Red blood cells (RBCs) can stack up or aggregate into rouleaux (singular: rouleau), which are formed by the distinct discoid shape of vertebrate cells. The discoid RBCs' flat surface offers them a lot of surface area to cling to and make contact with, creating a rouleau. Because of them, the ESR (erythrocyte sedimentation rate) increases when the plasma protein concentration is high. This serves as an all-purpose indicator of sickness.

Infections, multiple myeloma, Waldenström's macroglobulinemia, inflammatory and connective tissue disorders, and malignancies are among the illnesses that can result in rouleaux production.

Answer:

a) is the correct option

When epiphyses fuse to the diaphysis, full adult height is attained.

The epiphysis is just the round end of a very long bone, which is located at the joint with the bone that is close to it (s). The metaphysis, which includes the epiphyseal plate, can be found in the long bone between the epiphysis and the diaphysis (the long middle region of the long bone) (growth plate). At the joint, the epiphysis is covered by articular cartilage; below a certain covering is a zone called subchondral bone that is identical to the epiphyseal plate. The epiphysis is composed of red bone marrow, which is responsible for the production of red blood cells.

There is a developing zone of cartilage that sits between a long bone's diaphysis and both of its epiphyses (the epiphyseal plate). When a child reaches skeletal maturity, which typically occurs between the ages of 18 and 25, all of the cartilage is replaced by bone, and the diaphysis and both epiphyses become fused together (epiphyseal closure). This process involves the active osteoblasts that deposit bone structural proteins replacing the hyaline cartilage that was previously present in the epiphyseal area.

To assess if an organism expressing a dominant characteristic is homozygous or heterozygous, a test cross can be used.
Back crosses are made between F1 generation plants and any of the parent plants, whereas test cross is made between F1 generation plants with dominant phenotypes and the homozygous recessive parent.

The phenotypes of the children can be used to identify the unknown genotype. If combining the recessive phenotype individual with the unknown dominant phenotype (PP or Pp genotype) results in solely dominant phenotypes (no recessive), then the unknown individual is homozygous dominant.
No matter if you are examining one gene or several genes, test crosses work on the same principle: you are pairing a person with a dominant phenotype but an unknown genotype with a person who is homozygous recessive for all relevant genes.
