What do animals do with the carbon dioxide produced in their cells during cellular respiration?

Answers

Answer:

Explanation:

During cellular respiration animal cells combine oxygen with food molecules to release energy to live and function. Remember that cellular respiration produces carbon dioxide as a waste product. ... They release the carbon dioxide into the air as a waste product. Plants help animals and animals help plants.

The carbon dioxide produced in animal cells during cellular respiration is considered a waste and must be disposed of accordingly.

The carbon dioxide generated from cellular respiration in animal cells must be disposed off the cell because their build-up can be toxic to the cell.

Being a gas, carbon dioxide is got rid of by diffusing out of the cell while the oxygen required for cellular respiration usually diffuses in.

When carbon dioxide is allowed to accumulate in the cell, it might affect other processes such as the partial pressure of oxygen in the cell, and so on.

atmosphere
biosphere
geosphere
hydrosphere

Answers

Answer:

Hydrosphere

Explanation:

When the sun impacts weather, an interaction with the hydrosphere takes place. The hydrosphere is the part of the earth that is enveloped by water. Water exists in three different forms on the earth based on diverse factors.

Weather is the atmospheric condition of a place over a short period of time.

The sun causes the warming of the earth surface which leads to evaporation of water vapor into the atmosphere.

This water in the atmosphere is forms rainfall, one of the elements of weather.

The sun causes an impact on weather by causing evaporation of water into the atmosphere.

This interaction takes place in the hydrosphere.

The statement describes the property of the asthenosphere, which is that the pressure is higher than the earth's crust.

What are the properties of the asthenosphere?

The asthenosphere is the denser and weaker layer below the mantle of the lithosphere. It is approximately 100 kilometers (62 mi) and 10 kilometers (255 mi) below the Earth's surface.

The asthenosphere is the part of the upper mantle  below the lithosphere that participates in plate tectonic movement and isostatic regulation. It consists of peridotite, a rock that mainly contains the minerals olivine and pyroxene.

The asthenosphere is the mechanically weak and flexible region of the Earth's upper mantle. It is located under the lithosphere, approximately 80-200 kilometers below the earth's surface and extends to a depth of 700 kilometers.

C. Households exchange money for products in resource markets.
D. Household expenditures flow to the product market in exchange

Answers

The statement best summarizes the role of households in the flow of goods is households exchange money for products in resource markets. Thus, option C is correct.

Who are the consumers among households?

The final consumers of the goods and services produced by the businesses are the households. According to their tastes and preferences, they create demand in the market. The businesses supplied and produced goods in response to customer demand. As a result, a nation's production line is determined by its households.

To run a business, workers are needed, and business owners, managers, and employees also have families. In return for labor, the business pays wages, which increase household income.

Therefore, A company's output may fall somewhere in the middle of these two ideas. A landscaping company, for instance, might offer a homeowner a service and sell them a tree as a product.

The tool which is typically used for testing nitrates is: C. soil testing kit

Nitrogen is a chemical element with the symbol "N" and it has an atomic number (number of protons) of 7.

Basically, nitrogen is found in group (5) of the periodic table and as such it has 5 electrons in its outermost shell.

Oxygen is a chemical element with the symbol "O" and it has an atomic number (number of protons) of 8.

Generally, when nitrogen and oxygen react chemically, they produce a compound known as nitrogen dioxide.

In Chemistry, nitrates are chemical compound that comprises nitrogen and oxygen.

Answers

The group of choices is as follow:

A. RNA polymerase are added to the PCR mix to design random primers  

B. If detecting viral infection by PCR, the primers must not be complimentary (match) to regions of human DNA  

C. Pairs of primers must be designed, one to start amplification with Taq polymerase, the other to start amplification with human polymerase  

D. Primers are optional if you want to amplify all DNA within a sample

Answer:

The correct answer is - B. If detecting viral infection by PCR, the primers must be complementary to regions of human DNA.

Explanation:

Short, single-stranded segments of DNA sequences utilize in the real-time PCR or polymerase chain reaction technique are called primers. Primers used to hybridize the region of the segment needed to be amplified.

The human polymerase enzyme is not used in the PCR reaction and requires a 3'OH group to synthesize the DNA by amplification which is possible only in the presence of primers as they have a 3'OH.

Discuss how constraints related to biology and management affect the choice of a crossbreeding system. Please be descriptive.

Answers

Answer:

Some important constraints:  

-Plant breeding: autogamy and allogamy, self-sterility, etc  

-Animal breeding:  trait compatibility

- Breeding systems in general (i.e., both in plants and animals): barriers for sexual reproduction  

Explanation:

Crossbreeding systems consist of the breeding between two breeds in order to develop progeny with particular advantageous phenotypic traits. In-plant crossbreeding systems, it is imperative to have into account whether the plant is autogamous (reproducing by self-pollination) or allogamous (reproducing by cross-fertilization), because it will affect the fitness of the progeny resulting from these breeds. Moreover, the biological mechanisms of self sterility and compatibility must be also taken into consideration. In-animal breeding systems, it is important to have into consideration that phenotypic traits we desire to obtain in the progeny must be compatible between races. In addition, the barriers for sexual reproduction are also an important issue both in plant and animal breeding systems, it thus being impossible, for example, to get a breeding between Chihuahua and Great Dane dogs.
