The process that produces gametes in animals is meiosis.

Meiosis is a specialized type of cell division that occurs in the reproductive cells, or germ cells, of animals. It involves two rounds of cell division, resulting in the production of four haploid daughter cells, each with half the number of chromosomes as the parent cell.

During meiosis, the genetic material is shuffled and recombined through processes such as crossing over and independent assortment. This genetic variation contributes to the diversity of offspring produced through sexual reproduction.

Explanation:

Animals and plants need to get rid of carbon dioxide (c02), this process is called respiration. Respiration happens when the plant/animal breaths in air and releases it as carbon, carbon then moves from fossil fuels to the atmosphere where they are burned. When humans burn fossil fuels to power cities, power plants, cars, and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas.

Answer:

1.) Coughing involves a quick contraction of the diaphragm muscle, forcing air

through the respiratory pathway, and dislodging mucus or other harmful

particles

3.) Cilia function like a filter, trapping dust and pollen in the nose,

4.) Mucus traps bacteria and viruses to be removed or swallowed.

Explanation:

Coughing involves a quick contraction of the diaphragm muscle, forcing air out while the cilia act like a filter, trapping dust and pollen in the nose. Mucus traps bacteria and viruses to remove or swallow. So, the correct options are A, C and D.

The respiratory system is defined as the network of organs and tissues that help us breathe which includes the airways, lungs, and blood vessels. The muscles that power the lungs are also part of the respiratory system where these parts work together to move oxygen throughout the body and clear out waste gases like carbon dioxide.

Respiratory system works in that way with the immune system by keeping the human from getting sick by bacteria and viruses are removed or swallowed by mucus, while the cilia act like a filter, trapping dust and pollen in the nose.

Thus, coughing involves a quick contraction of the diaphragm muscle, forcing air out while the cilia act like a filter, trapping dust and pollen in the nose. Mucus traps bacteria and viruses to remove or swallow. So, the correct options are A, C and D.

Different skin color within a species is an example of genetic biodiversity. Therefore, option (A) is correct.

Genetic biodiversity refers to the variety of genes and genetic traits that exist within a population or species. It is a fundamental aspect of biodiversity, as it underpins the ability of species to adapt to changing environmental conditions and to maintain resilience in the face of threats such as disease, climate change, and habitat loss.

Genetic biodiversity arises from mutations, genetic recombination, and other processes that generate new genetic variation within populations. This diversity provides the raw material for natural selection to act upon, allowing organisms with advantageous traits to survive and reproduce.

Genetic biodiversity is important for ecosystem functioning and for the conservation of species, as it helps to ensure that populations are able to adapt to changing conditions and maintain their long-term viability. The loss of genetic biodiversity can have significant negative impacts on populations and ecosystems, making it an important focus of conservation efforts.

Answer:

50%

Explanation:

Roan color is controlled by two codominant alleles. Let us assume that the red color allele is R and the white color allele is W. Thus, the roan color would be RW.

Roan color cow is crossed with a white bull;

    RW   x   WW

RW   RW   WW   WW

RW = roan = 50%

WW = white = 50%

1/2 or 50% of the offspring would be roan color while the remaining 1/2 or 50% would be white in color.

substrate specificity. The active site of an enzyme is very specific to its substrates as it has a very precise shape. This results in enzymes being able to catalyze only certain reactions as only a small number of substrates fit in the active site. This is called enzyme-substrate specificity.

Answer:substrate specificity. The active site of an enzyme is very specific to its substrates as it has a very precise shape. This results in enzymes being able to catalyze only certain reactions as only a small number of substrates fit in the active site. This is called enzyme-substrate specificity.

Explanation:Enzymes and substrates share specificity in that an enzyme will only react with a specific substrate • This is because the active site is complementary in both shape and charge to a given substrate • The model by which this is known is ‘lock and key’ as the substrate is a precise structural fit for the enzyme, much like a lock and key • When the enzyme and substrate bind, they form an enzyme-substrate complex, before the substrate is catalytically converted into a product

Answer:

the kind of material it is moving through

Explanation:

Sound wave is a type of mechanical wave, which requires a medium to travel, unlike longitudinal waves that can travel through vacuums. Since, sound waves travel through mediums, the KIND OF MEDIUM/MATERIAL it is traveling through has a role to play on how fast it moves.

Sound waves move faster in materials whose molecules are closely packed together than those with loosely packed molecules. This is why sound waves naturally travel faster in SOLID materials. Therefore, the the kind of material the sound wave is moving through affects how fast it moves.
