At high altitudes, air is less dense than at sea level because of decreased air pressure. This means that a person who ascends to high altitudes takes in fewer oxygen molecules per breath. Describe and explain an immediate response that occurs in the circulatory system when a person first reaches high altitudes. Use vocabulary from class.

Answers

Answer 1

An immediate response that occurs in the circulatory system when a person first reaches high altitudes is that the heart beats faster to meet the demand for oxygen that the body needs.

What are the main effects of altitude?

The higher it is, the worse the symptoms, which include

headacheshortness of breathrapid heartbeatamong others

Not everyone has these symptoms when they go to high-altitude places, but it is also not possible to know who will or will not feel something.

With this information, we can conclude that An immediate response that occurs in the circulatory system when a person first reaches high altitudes is that the heart beats faster to meet the demand for oxygen that the body needs.

If you have a hamster with long fur, what possible genotypes could the hamster have?

Answers

Answer:

Ll, Ll, LL

Explanation:

So, there is one thing we must remember to answer this:

1# dominant genes(long fur) are expressed over reccesive genes(short fur)

Knownign that dominant is over reccesive, it is simple. If the genotype was Ll or lL then the dominant long fur would be expressed over reccesive short fur. Long fur - Ll, lL

Next, we know that LL will be long fur since its both long and long, and there is no possibility for short fur. Long fur - LL

Finally. we have ll, and since there isnt a dominant long fur, and only reccesvie short, then this cannot be long fur. Short fur. - ll

List one organism and describe all of its adaptations.​

Answers

Adaptation is a mechanism of species to survive and reproduce in their environments, adjusting to selective pressures. Cactus: leaves, stems, spines.

What is adaptation?

In biology, adaptation might be defined as the mechanism of organisms to improve their fitness in the environment in which they live, adjusting to different changes and selective pressures acting on them.

Adaptation involves molecular, physiological, morphological, and behavioral changes.

For these changes to persist and be transmitted from generation to generation, they must increase the individual's fitness. They must increase the individual survival and reproductive probabilities, making it more competitive.

A good and easy to unsderstand example of adaptation is the cactus.

Cactusses are plants adapted to dry and hot environments like deserts, where water availability is scarse and temperatures are high.

To avoid dehydration, cactusses have developed wide palmated or cilindirical stems and reduced or vestigial leaves.

They use stem tissues to store water. Vestigial or reduced leaves to avoid transpiration and water loss.

As their leaves are not developed, their stems photosynthetize to produce organic compounds.

Some species are very rich in water and nutrients, so they turn to be covetted by other species. Animals living in the same environment look for them as a source of food.

To avoid predation, cactusses have developed large and numeros spines that are leaves modifications. This is another adaptation to avoid being eaten by animals and avoid loosing water through leaves.

Why do scientists that work on producing biofuel from algae need to understand algal reproduction?

Answers

Answer:

Due to more production of biofuel.

Explanation:

Scientists that work on producing biofuel from algae need to understand algal reproduction because reproduction of algae is responsible for the higher productivity of biofuel. Algae produce by both sexually and asexually means from the fusion of male and female gametes and from only one parent. Algae needs carbondioxide gas and light for the growth and reproduction so if these factors are present in sufficient amount then the algae increases in growth and reproduce rapidly which leads to higher production of biofuel.

Fuels acquired from biomass is called biofuel. Biomass can be a plant, animal waste or algae. It is a reservoir of renewable energy and can be supplied readily.

Scientists operating on biofuel need to learn about algal reproduction as algae is the major source of biofuel production.

The potency of biofuel depends on the generative cycle of the algae.

Algae can propagate asexually by means of spores and vegetatively or through sexually by producing the gametes.

If the determinants like carbon dioxide and sunlight required for reproduction are present in the right quantity then the algae will thrive and proliferate rapidly, thus increasing biofuel production.

Therefore for increasing biofuel production, we need to know the reproductive methods of algae.

Explanation:

The development of CRISPR-Cas9 is significant for the scientific community because this development allows the scientists to activate gene expression instead of cutting the DNA. This technique allows the scientists and researchers to study the function of the gene. Before development, Cas9 enzymes produced by the CRISPR system binds to the DNA and cuts it by shutting the targeted gene off so this development of CRISPR-Cas9 enables the scientists to activate gene expression instead of cutting the DNA.

Animals are often paired based on physical traits and personal compatibility. Strong reproductive capability is the most important trait in animal breeding. Selective breeding combines ideal traits of animals to replicate in offspring. Swine are the only agricultural animal species that are currently crossbred.

Answers

Answer:

Selective breeding combines ideal traits of animals to replicate in offspring

Explanation:

Selective breeding is the process which involves choosing parents with particular characteristics to breed together and produce offspring with more desirable characteristics. It is also known as artificial breeding and provides both plants and animals with greater variation and higher chances of survival. Selective breeding can be used to produce plants with bigger and tastier fruits and vegetables, crops with greater resistance to pests and diseases, and bigger animals that can be used for meat or milk production. The process of selective breeding is of great importance to the farmer today as it has brought about greater economic advantages.

In the instance of the black-breed boar and the white-breed sow being matched for mating, the reason is to combine these desirable traits in their offspring. The black-breed boar produces quality meat while the white-breed sow has quality fertility. Mating between these two breeds will produce offspring which has both traits of quality meat production as well as quality fertility.
