Explanation:

Answer:

The correct answer would be "Fish will have the greatest genetic diversity because they receive genetic material from a male and female source".

Genetic diversity is defined as the variation in the total amount of genetic information among the individual of the population.

In sexually reproducing population, genetic diversity is present in high amount as compared to asexually reproducing population.

It is because of two reasons:

The genetic make of an individual is determined by 2 parents (father and mother).

The event of crossing over takes place during formation of gametes.

Together, they lead to the development of new combinations of alleles in an offspring which is different from both the parents.

Thus, fish would have the highest genetic diversity in their population.

Answer:Each muscle in the body is made up of cells called muscle fibers. Muscle fibers are long, thin cells that can do something that other cells cannot do—they are able to get shorter.

Explanation:

IM not sure if this would help but their you go.

Muscle fibers are the cells that make up each muscle in the body. Muscle fibers are long, thin cells with the unique ability to shrink. Most cells cannot do this.

Cross-striations are the most noticeable histological characteristic of muscle fibres, which are massive multinucleated cells. Many myofibrils with tiny cylinders made of bundle of myofilaments can be found in the cytoplasm.

Myofilaments are made up of both thick filaments primarily made of myosin and thin filaments primarily made of actin. Due to their regular overlap, which is kept in register from across diameter of the muscle fiber, the thick and thin filaments create the cross-striations.

Thus, the cells that make up each muscle in the body are known as muscle fibres. Long, thin cells called muscle fibres have the unusual ability to contract and expand. Most cells are unable to achieve this.

Answer:

Impact of double-stranded mRNA before translation would inhibit the binding of tRNA to mRNA ti synthesize protein.

Explanation:

The mRNA is a molecule that, with the exception of viruses with double-stranded RNA, has only one chain. It is in charge of conducting to the ribosomes the sequence of nucleotides that makes possible the translation and the synthesis of proteins.

Once the ribosome translates the information of each codon of the mRNA, a transfer RNA (tRNA) molecule, with a complementary anticodon, provides the amino acid corresponding to the translated codon.

If the mRNA were double-stranded, the translation process would be altered, since binding of the tRNA with the amino acid it carries and mRNA codon would not be possible, as well as the protein synthesis.

Answer:

When the chemical energy in food is transferred to cells in the body, the energy can be transformed into energy used by the body to do many things like run, ride a bike, do the dishes, pump the heart, and keep the body warm.

The chemical energy, which is needed by the organisms comes from the food. Food comprises organic molecules, which captivates energy in their chemical bonds.  

• The organisms generally use two kinds of molecules for chemical energy, ATP and glucose.  

• Both the molecules are utilized as fuels all through the living world.  

• Energy is the tendency to perform an activity. It is required by all the living species and every living cell to perform the processes of life.  

• Energy in the form of chemical energy is utilized to dissociate and form the molecules, and to transport several molecules through the cell membranes.  

• The organisms primarily use ATP and glucose for energy.  

Thus, the form of energy required by the living species to perform the essential activities of life is obtained from food.

Answer:

Explanation:

plants capture and store the energy they derive from light during photosynthesis in ATP molecules. ... When one phosphate group is removed by breaking a phosphoanhydride bond in a process called hydrolysis, energy is released, and ATP is converted to adenosine diphosphate (ADP).

The green plants store the food that is produced during this process as the six carbon sugar called glucose.

The term photosynthesis refers to the process by which green plants produce food by the use of carbon dioxide and water.

In this process, the green plants store the food that is produced during this process as the six carbon sugar called glucose.

(2) the placenta allows nutrients to diffuse from the mother to the embryo.

Explanation:

The placenta is a shared organ between the mother and the embryo. It diffuses the necessary nutrients from the mother to the future baby and the residues from this one to the mother, so that she can expel them. The placenta separates the mothers and the embryo blood, but it allows the diffusion of said nutrients and wastes through especial parts of the placenta with thin walls.

During a thunderstorm there are pretty high winds that can knock power lines down, lots and lots of rain, lightning that can easily strike down a power line, etc.

A simple rainfall could not hold enough power to block a radar signal

Sunshine does not effect anything see as it includes clear weather.

A tornado would also be another thing to consider though.
