Why is global warning considered a controversial issue?

Answers

answer: The global warming controversy concerns the public debate over whether global warming is occurring, how much has occurred in modern times, what has caused it, what its effects will be, whether any action can or should be taken to curb it, and if so what that action should be. In the scientific literature, there is a strong consensus that global surface temperatures have increased in recent decades and that the trend is caused by human-induced emissions of greenhouse gases.[1][2][3][4][5][6] No scientific body of national or international standing disagrees with this view,[7] though a few organizations with members in extractive industries hold non-committal positions,[8] and some have attempted to convince the public that climate change is not happening, or if the climate is changing it is not because of human influence,[9] attempting to sow doubt in the scientific consensus.

Answers

Hopes this helps:

Answer: In 1998 scientists discovered that fungi split from animals about 1.538 billion years ago, whereas plants split from animals about 1.547 billion years ago. This means fungi split from animals 9 million years after plants did, in which case fungi are actually more closely related to animals than to plants.

The elimination of rinderpest impacted the wildebeest population. What type of factor is rinderpest

Answers

Answer:

density-dependent, top-down factor

Explanation:

In biology, limiting factors are resources and other conditions in the environment whose presence/availability limit the population growth rate. Density-dependent factors refer to the conditions whose effects on the size/growth of the population vary depending on the population density. Some examples of density-dependent factors include diseases, competition, and predation, etc. These factors can exhibit a positive or negative correlation with the population size. Moreover, bottom-up population control (species limitation by resources) refers to limitations placed by resources allowing growth (e.g.,  food source or habitat), while top-down population control (limitation by enemies), refers to limitations placed by factors that control the death rate in the population (e.g., predation or diseases).

An electrocardiogram (ECG) provides information about: Group of answer choices the pressure of blood in the heart chambers the rhythm of heart contractions the speed of blood flow through the blood vessels the amount of oxygen in the blood as it leaves the heart

Answers

Answer:

the rhythm of heart contractions.

Explanation:

In Human anatomy, cardiac cycle can be defined as a complete heartbeat of the human heart which comprises of sequential alternating contraction and relaxation of the atria and ventricles, therefore causing blood to flow unidirectionally (one direction) throughout the human body.

Generally, the cardiac cycle occurs in two (2) stages;

1. Diastole : in this stage, the ventricles is relaxed and would be filled with blood.

2. Systole: at this stage, the muscles contracts and thus, allow blood to be pushed through the atria.

An electrocardiogram (ECG) provides information about the rhythm of heart contractions.

Additionally, the right atrioventricular valve (AV) also referred to as the tricuspid valve is located on the right dorsal side of the human heart. The right atrioventricular valve (AV) comprises of three (3) leaflets (flaps) which opens and closes in order to allow for the flow of blood from the right atrium of the human heart to the right ventricle. Also, the right atrioventricular valve is saddled with the responsibility of preventing blood from flowing backward in the mammalian heart.

If having long fur helps a guinea pig survive, what
would you expect to see change in the population
as it evolves?
DONE

Answers

The population would increase, since they live longer and more can mate and reproduce.

In a population with long fur, there will be more guinea pigs than short fur in the given scenario.

What is trait?

A trait, as it relates to genetics, is a unique feature of an individual.

If having long fur helps a guinea pig survive, we can expect the long-furred trait to become more common in the population as it evolves.

This is because guinea pigs with long fur would have an advantage in colder environments, allowing them to retain body heat more effectively and survive longer.

As a result, longer-furred guinea pigs are more likely to survive and reproduce, passing on their long-furred trait to their offspring.

As this process continues over many generations, the proportion of guinea pigs with long fur in the population will increase, while the proportion with short fur will decrease.

Thus, this can be expected to see change in the population as it evolves.

True or False: Purine is connected to pyrimidine using oxygen bonds.​

Answers

Answer:

False

Explanation:

In DNA double helix molecule, there are four types of nitrogenous bases: adenine, guanine, cytosine and thymine. Purines (i.e., adenine, guanine) and pyrimidines (i.e., cytosine and thymine) hold DNA strands together via hydrogen bonds. In base pairing, guanine always pairs with cytosine through 3 hydrogen bonds, while adenine always pairs with thymine by 2 hydrogen bonds. Hydrogen bonds are a type of dipole–dipole interaction where a hydrogen atom is covalently bonded to a very electronegative atom (e.g., Nitrogen or Oxygen).

Answers

Answer:

The correct answer is C. In North and South America, a majority of the population is located on the coasts.

Explanation:

Historically, the vast majority of civilizations have sought to establish their urban centers around bodies of water, be they rivers or seas, that allow them a rapid expansion outward as well as channels through which to channel trade. Thus, it can be seen how throughout the world and especially the American continent, large cities and population centers are located primarily on the coasts. Examples of this situation are Vancouver in Canada, New York and Los Angeles in the United States, Rio de Janeiro in Brazil or Buenos Aires in Argentina.

What is Climate Change?


Explain your answer.

Answers

What is Climate Change?

Climate change is a change in the usual weather found in a place.

How it helps us:

Studying the climate helps us predict how much rain the next winter might bring, or how far sea levels will rise due to warmer sea temperatures. ... We can also see which regions are most likely to be affected by extreme weather, or which wildlife species are threatened by climate change.

How it works:

As the earth's atmosphere heats up, it collects, retains, and drops more water, changing weather patterns and making wet areas wetter and dry areas drier. Higher temperatures worsen and increase the frequency of many types of disasters, including storms, floods, heat waves, and droughts.

How it affects us:

Human health is vulnerable to climate change. The changing environment is expected to cause more heat stress, an increase in waterborne diseases, poor air quality, and diseases transmitted by insects and rodents. Extreme weather events can compound many of these health threats.

Why can't weeds take over the world? In other words, what limits the growth of populations?

Answers

Answer and Explanation:

Many elements can limit population growth. The main elements that can cause this are the lack of resources necessary for the life and development of living beings and the lack of space to be taken by them. In relation to weeds, these resources can be the availability of sun, amount of soil, soil fertility, availability of water and space. However, these plants are very resistant to the lack of these resources, and what most limits their growth is human interference.

Weeds are unfavorable to agriculture and other human activities. This makes humans fight the population growth of these plants using chemical products and even physical strategies. This interference prevents weeds from taking over the world.

Tt

Explanation:

Hello. I believe that you are only referring to question 2, since question 3 does not present all the answer options. As such, the offspring of a cross between a tall pea plant (TT) and a low pea plant (tt) would be completely "Tt."

To achieve this result, you must make a Punnett Square, which is a frame that allows you to combine the alleles of the parents in a cross to project the alleles of the offspring.

Alleles are those characterized by the letters associated with characteristics. As you saw in the question above, tall pea plants have "TT" alleles that are dominant alleles, while low pea plants have "tt" alleles that are recessive alleles. In this case, to use Punnett Square, you must put the alleles of one parent in the first row and the allele of the other parent in the first column. Then just combine each allele, as shown below:

    T    T

t    Tt   Tt

t    Tt   Tt

As you can see all the offspring will have the "Tt" alleles. This means that the entire offspring will be tall pea plants. This is because the recessive allele "t", which is related to pea plants, can only be expressed in the presence of another recessive allele. However, the dominant "T" allele, which is associated with tall pea plants, can be expressed in any situation.

how does the method of obtaining energy for fungi differ from that of plants and animals?​

Answers

Answer:

From animals they need energy to get it fungi they can make it

Explanation:

Answer:

Fungi obtain their energy from absorbing either dead or living organisms.

Explanation:

Fungi are heterotrophic, meaning they cannot produce their own food, unlike plants. Plants are able to perform photosynthesis to obtain their energy by converting carbon dioxide and water into oxygen and glucose. However, unlike animals who go out to either hunt or forage food (for example, a deer eating grass or a wolf hunting a bunny), fungi absorb nutrients from dead or living organisms. For example, a fungi might be seen next to a decaying oak log. Or, it might be seen on the bark of a living tree.
