The main function of protein is to carry oxygen, speeds up chemical reactions and fights infections. Therefore, the correct statement is option B.

Proteins are a class of biomolecules that play an important role in the structure, function, and regulation of cells and tissues in living organisms. Protein constitutes the long chains of amino acids forming complex three-dimensional structures.

Proteins perform various functions in the body, such as carrying out chemical reactions, transportation of molecules, carry oxygen, and defending the body against infections and diseases.

Hemoglobin is also a protein that carry oxygen from the lungs to the rest of the body. Enzymes are also proteins that lowers the activation energy required for the reaction to occur and speed up the chemical reactions whereas antibodies are another class of proteins that bind to specific antigens for destruction by the immune system, thereby, protecting the body from various diseases.

Therefore, proteins help in carrying oxygen, speeds up chemical reactions and fights infections.

Predators have advantage over the prey as the prey are vulnerable and get hunted and also the prey population is regulated by the predator.

Predators are those animals which prey on other animals, that is, they obtain their nutrition by hunting down and eating other animals. Prey are those animals which get hunted by the predators.

Predators are a vital part of an ecosystem and have advantages over a prey as the prey is vulnerable and gets hunted down. Due to this, the predators are able to keep the population of prey in check and also help eliminate the old and sick animals from the prey species. They also ensure the transfer of energy to the next trophic level and by feeding on animals they also help reduce the waste in the environment.

Answer:

Explanation:

Option (A) The likelihood of a Large polar molecule passively diffusing through a plasma membrane alone without aid of a transport protein is the lowest. By both its size and the moist interior of the membrane.

The phospholipid bilayer is difficult for large hydrophilic polar or ionic molecules to pass. Because the hydrophobic tails in the interior of the phospholipid bilayer reject charges, charged atoms or molecules of any size cannot traverse the cell membrane by simple diffusion.

Because they are positively charged, sodium cations cannot cross the plasma membrane and hence cannot enter or leave the cell.

Individuals with one X and one Y sex chromosome will usually have male body parts. The presence of the Y chromosome determines a person's biological sex. Whatever set of chromosomes a person is born with cannot be changed. This is because chromosomes are present in all the cells that make up our body.

The Y chromosome carries a male-determining gene called SRY. Expression of the SRY gene results in a protein that initiates the processes that lead to the development of the male reproductive organs. While the XX chromosome carries the female determining gene.

Anterior to the knee is a specialized bone called the patella, which is also known as the kneecap.

A small triangular bone called the patella, sometimes referred to as the kneecap, is located at the front of the knee joint. This is a specialized bone that is important for stability and motion of the knee. The quadriceps tendon, specifically, is where the patella is located within the tendon of the quadriceps muscle group. It serves as a fulcrum, improving the mechanical advantage of the quadriceps muscles and providing leverage during knee extension.

To determine which traits are dominant in an organism like a pea plant i.e whether it is homozygous or heterozygous for the trait, a test cross is performed.

To establish if a heterozygote or a homozygote was present in an organism that expressed a dominant characteristic. Breeders of plants and animals still utilise a method known as the test cross. A test cross involves mating a dominantly expressed organism with a homozygous recessive organism with the same trait. All F1 offspring will be heterozygotes exhibiting the dominant characteristic if the dominant-expressing organism is a homozygote. The F1 progeny will instead display a 1:1 ratio of heterozygotes and recessive homozygotes if the dominant expressing organism is a heterozygote. Mendel's premise that pairs of unit components segregate equally is further supported by the test cross.

If an organism has homozygous alleles for the characteristic, all of the organisms in the ensuing F1 generation will exhibit the trait, and their genotypes will be heterozygous for it.

The F1 generation, however, will contain half of the organisms with the dominant phenotype and half with the recessive phenotype if the organism has a heterozygous genotype for the dominant characteristic.

The tall (dominant) or dwarf (recessive) aspect of the pea plants can be used to illustrate this hybrid, as shown.

The parent's genotype will be homozygous dominant (TT) if the outcome is entirely tall plants, and heterozygous dominant (TT) if the outcome is 50% tall and 50% dwarf plants (Tt).

If a homozygous tall pea plant (TT) and a homozygous short pea plant (tt) are crossed, the resulting offspring will be all heterozygous (Tt) for the trait of plant height.

Each parent will contribute one allele for the trait of plant height to each offspring, and the alleles that code for tall and short plant height are dominant and recessive, respectively.

The cross can be represented using a Punnett square, which is a tool that shows the possible combinations of alleles that can result from a genetic cross. The Punnett square for the cross between a homozygous tall pea plant and a homozygous short pea plant would look like the attached picture.

During photosynthesis, plants trap light energy using their leaves. Plants use the energy of the sun to transform water and carbon dioxide into a sugar called glucose. Plants use glucose as a source of energy and to create other compounds like cellulose and starch.

The process through which plants convert solar energy (from the Sun) into chemical energy is known as photosynthesis. The chemical energy is available as food and is stored in the plant as sugar. Everything a plant needs to begin photosynthesis is already present in its leaves.

Nuclear fusion is the method used to power the sun. The extreme pressure and temperature in the sun's core lead to the separation of the nuclei from their electrons during nuclear fusion. One helium atom is created when two hydrogen nuclei combine. Radiant energy is released during the fusion process.

2) Exocytosis is a sort of passive transport, whereas the other three alternatives (Active Transport, Sodium-Potassium Pump, and channel protein) are all types of active transport.

3) "Cellulose" does not fit since it is a carbohydrate that is a key component of plant cell walls, but "selectively permeable," "proteins," and "lipid bilayer" are all cell membrane-related terms.

It is to be noted that the transportation of molecules across a membrane against a concentration gradient requires the addition of energy. Where this occurs, it is called Active Transport.
