Gametes are the structure required for fertilization and are formed from germ cells through meiosis. Gametes produced by an organism contain a combination of genes from that organism which is different in every individual due to independent assortment.

When the alleles of two different genes get sorted into gametes independently of one another is referred to as independent assortment.

In other words, different alleles and genes are independently transferred to offspring during the meiosis in reproduction through the fusion of gametes.

Thus, it can be concluded that gametes produced by an organism contain a combination of genes from that organism which is different in every individual due to independent assortment.

The statement that best describes human influence on the biogeochemical cycle is as follows: increased eutrophication caused by high levels of nitrogen and phosphorous, which is option A.

Eutrophication is the ecosystem's response to the addition of artificial or natural nutrients, mainly phosphates, through detergents, fertilizers, or sewage, to an aquatic system.

Eutrophication is one major effect of the anthropogenic activities that release inorganic nutrients such as phosphate, nitrate etc into aquatic ecosystems.

However, eutrophication has its negative impacts on biogeochemical cycle as it alters the cycling of these nutrients.

Therefore, the statement that best describes human influence on the biogeochemical cycle is as follows: increased eutrophication caused by high levels of nitrogen and phosphorous.

The change in crab color is an example of Disruptive selection because two extreme colors were preferred over the more moderate color. Thus, the correct option for this question is D.

Natural selection may be defined as the selection of a few individuals from any given population according to their favorable variations.

In 1950, the crab color is in the form of stabilizing selection, while in 1990, it changes to disruptive selection that favors the two extreme colors over the intermediate one.

Disruptive selection occurs when environmental conditions changes in two different directions. Due to which variance increases in population.  

Therefore, the correct option is D.

Answer:

B, It changes from 379 J to 243 J.

Explanation:

"It changes from 379 J to 243 J" best describes the potential energy of this system.

Total energy in a system can be divided into two main components: kinetic energy and potential energy. The given information states that the kinetic energy of the system changes from 296 J to 432 J. However, no direct information is provided about the change in potential energy.

Since the total energy in the system remains constant at 675 J, any change in kinetic energy must be compensated by an equal and opposite change in potential energy to maintain the overall energy balance.

If the kinetic energy increases from 296 J to 432 J, the potential energy must decrease to maintain a total energy of 675 J. Therefore, the potential energy changes from a higher value of 379 J (initial potential energy) to a lower value of 243 J (final potential energy). This change in potential energy is consistent with the increase in kinetic energy from 296 J to 432 J, ensuring the conservation of total energy in the system.

Active transport moves molecules from one side of the membrane to the other against their electrochemical gradient. It needs energy to occur. The answer is active transport.

Active transport is one of the three cellular transmembrane transports. The other two are passive transport and simple diffussion.

Active transport acts against the electrochemical gradient, so it does need the energy to transport substances. It carries molecules from a low concentration side of the membrane to a high concentration side.

The used energy comes from ATP (Na-K bomb) or the membrane's electric potential.

Carrier proteins are involved in active transport.

Hence, the process that requires cellular energy to move a substance against its concentration gradient is called Active transport.

One or two purple alleles in flowering pea plants will result in purple blooms.  so there will be 50 percent ratio. This is because one purple gene causes enough pigment to be synthesized to produce all purple flowers.

A dominant allele is a variant of a gene that causes a specific trait even when other alleles are present. A functional protein is usually encoded by a dominant allele. Because one copy of the allele produces enough enzyme to furnish a cell with plenty of a given product, it is dominant.

As a result, the purple allele has a dominant role, while the white allele has a recessive role.

phoresy - a commensalistic relationship in which one organism is transported by another.

monogamy - having one mate for a whole life span

mutualism - a symbiotic relationship between two organisms in which

both species receive some type of benefit

polyandry - when females mate with multiple males

polygyny - when males mate with multiple females

parasitism - a relationship between two or more organisms of different

species in which one benefits and the other is harmed

Symbiosis is the name given to any close and long-term interaction between two different species.

This interaction can be beneficial to one part only and harmful to the other (parasitism), it can be beneficial to all parts (mutualism), or it can benefit one part without influencing neither positively nor negatively the other (commensalism).

A mating system refers to how a group is organized in terms of sexual behavior. When it comes to animals, the phrase refers to which males and females mate when certain conditions are met. Monogamy, polygamy (including polygyny, polyandry, and polygynandry), and promiscuity are all recognized systems that lead to various mate choice outcomes and so influence how sexual selection operates in the species that practice them.
