Answers

Answer 1

Answer:

1. The enhanced greenhouse effect disrupts the Earth's climate equilibrium and has led to an increase in the global average surface temperatures.

2. Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"   1 — warming that results when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping.

3. Greenhouse gases absorb some of the energy and trap it in the lower atmosphere. Less heat radiates into space, and Earth is warmer. ... Carbon dioxide, methane, water vapor, and nitrous oxide are naturally present in Earth's atmosphere.

4. Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change.

5. As climate change caused by burning fossil fuels drives temperatures higher, the ocean warms, causing it to expand. ... Scientists have found that water draining from melting glaciers and ice sheets in polar and mountain regions is now also contributing to this rise in sea levels.

Answer 2

Answer: 1. Necessary because it keeps heat in and keeps the planet at the right temperature for life.

It can harm the planet if more pollution occurs and the greenhouse gas effect traps too much heat and causes global warming. 2. Scientists attribute the global warming trend observed since the mid-20th century to the human expansion of the "greenhouse effect"1 — warming that results Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. The greenhouse effect keeps Earth's climate comfortable when the atmosphere traps heat radiating from Earth toward space. Certain gases in the atmosphere block heat from escaping. 3. Human activities contribute to global warming by increasing the greenhouse effect. ... Greenhouse gases let the sun's light shine onto the Earth's surface, but they trap the heat that reflects back up into the atmosphere. In this way, they act like the insulating glass walls of a greenhouse. 4. Carbon sequestration is the process of capturing and storing atmospheric carbon dioxide. It is one method of reducing the amount of carbon dioxide in the atmosphere with the goal of reducing global climate change. Geologic carbon sequestration is the process of storing carbon dioxide (CO2) in underground geologic formations. The CO2 is usually pressurized until it becomes a liquid, and then it is injected into porous rock formations in geologic basins. 5. As climate change caused by burning fossil fuels drives temperatures higher, the ocean warms, causing it to expand. This expansion in turn causes sea levels to rise. ... There is now so much warming baked in to the global climate system that sea levels will continue to rise for centuries.

Transcription of the trp operon is decreased when tryptophan interacts with the _____
- co-repressor
- repressor
- inducer
- promoter
- operator

Answers

Transcription of the trp operon is decreased when tryptophan interacts with the repressor, option B is correct.

When tryptophan interacts with the repressor protein in the trp operon, it forms a complex that binds to the operator region. This binding prevents the RNA polymerase from accessing the promoter region, thereby decreasing transcription of the trp operon.

The repressor protein is normally inactive in the absence of tryptophan. However, when tryptophan levels are high, tryptophan molecules bind to the repressor, causing a conformational change that enables the repressor to bind to the operator. This binding effectively blocks the RNA polymerase's access to the promoter, inhibiting the transcription of the trp operon, option B is correct.

1) people

2) grass

3) rocks in the mountains

4) nylon tent

5) wooden kayak

Answer:

1) people

2) grass

Explanation:

The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.

Abiotic factors are physical and chemical components of the ecosystem. These are the non-living elements. Biotic factors are all the living components in the ecosystem.  

Biotic and abiotic factors influence the survival and reproduction of living beings. They are related and in constant interaction. If one of these components is removed, the whole ecosystem will change because its equilibrium has been altered.  

Every abiotic component influence organisms and their survival and reproductive rates.

A few examples of the abiotic factors are solar light, minerals, water, air, gases, soil, and humidity.

Examples of biotic factors are plants, animals, insects, microorganisms, etc.

-------------------------------------------------------------------------------------------------------------

The biotic factors of the provided list are:

People, which is a group of individuals composed of cells -which is the basic unit of life-. They grow, reproduce and survive. Grass, as one or many species of vegetables that are also multicellular. They grow, reproduce, and survive.

The abiotic factors are:

Rocks, which are non-living things composed mainly of mineralsTent, which is also a non-living thing, is artificially made by humans.

In my opinion, the wooden kayak is a gray zone, meaning that it might be confusing. A kayak is an abiotic element with no life and is built by men. But it is constructed of wood. The wood originates in trees that are living beings, they are composed of cells, and they used to be alive. However, when talking about the kayak wood, we are referring to dead tissue. It is not alive anymore. Its cells are dead so, their whole system is not working. It is now composed of minerals and other elements with no life, and it has been modified and processed to build the kayak.

So my opinion is that the wooden kayak is an abiotic factor.

Choose the correct climate for: grasslands near the equator



a low latitude climates


b dry mid-latitude climates


c humid continental climate

Answers

The most appropriate climate for grasslands near the equator would be a low latitude climate. This region has a tropical wet-dry climate that has a prolonged dry season. During the dry season, the land becomes parched and the vegetation dies out.

However, the grasses have extensive root systems, enabling them to survive long periods of drought. During the wet season, the grasses become green and grow quite fast to feed the herbivores that live in this region. This climate is suitable for the grasslands near the equator because the temperatures are high and the rainfall is irregular.

Therefore, the grasslands experience both a wet and dry season each year, which affects the flora and fauna. The low-latitude climate is characterized by high temperatures and high rainfall. This type of climate is found in areas near the equator, where the sun's rays are almost perpendicular to the earth's surface, resulting in high temperatures.

The grasslands are subject to strong sunlight, but they also require a certain amount of rainfall to survive. The grasslands near the equator, therefore, require an environment that is humid and receives regular rainfall but still experiences dry periods that are long enough to allow the grasses to thrive.

If haploid for an organism is 30 individual chromosomes, how many individual chromosomes would a somatic cell for this organism possess?
a. 15
b. 10
c. 90
d. 60
e. 30

Answers

A somatic cell for this organism would possess 60 individual chromosomes. Therefore, the correct answer is d. 60.

If the haploid number of chromosomes for an organism is 30, it means that each gamete (sex cell) of that organism contains 30 individual chromosomes. Gametes are haploid cells, meaning they only have one set of chromosomes.

In contrast, somatic cells are diploid cells, meaning they contain two sets of chromosomes. The diploid number of chromosomes is typically denoted as 2n. Therefore, to determine the number of individual chromosomes in a somatic cell, we multiply the haploid number (n) by 2.

For the given organism with a haploid number of 30 individual chromosomes, a somatic cell would possess:

Abraham, Inc., a New Jersey corporation, operates 57 bakeries throughout the northeastern section of the United States. In the past, its founder, James Abraham, owned all the companys outstanding common stock. However, during the early part of this year, the corporation suffered a severe cash flow problem brought on by rapid expansion. To avoid bankruptcy, Abraham sought additional investment capital from a friend, Dennis Bostitch, who owns Highland Laboratories. Subsequently, Highland paid $700,000 cash to Abraham, Inc., to acquire enough newly issued shares of common stock for a one-third ownership interest. At the end of this year, the accountants for Highland Laboratories are discussing the proper method of reporting this investment. One argues for maintaining the asset at its original cost: "This purchase is no more than a loan to bail out the bakeries. Mr. Abraham will continue to run the organization with little or no attention paid to us. After all, what does anyone in our company know about baking bread? I would be surprised if Abraham does not reacquire these shares as soon as the bakery business is profitable again." One of the other accountants disagrees, stating that the equity method is appropriate. "I realize that our company is not capable of running a bakery. However, the official rules state that we must have only the ability to exert significant influence. With one-third of the common stock in our possession, we certainly have that ability. Whether we use it or not, this ability means that we are required to apply the equity method."Question How should Highland Laboratories account for its investment in Abraham, Inc.? he second quartile for the numbers: 231,423,521.139347,400,345 is A 231 B. 347 C330 D. 423 47.
