Answer:

Every cell performs a type of cellular respiration as it is required to produce energy. The point of cellular respiration is to turn high-energy molecules, know as glucose, into ATP, a form of usable energy. There are two types of respiration, aerobic and anaerobic. Aerobic goes through 3 stages and produces the most ATP by using oxygen and releasing carbon dioxide. Anaerobic does the same job but only uses one stage and produces much less ATP. This process gives the cell energy and continues the carbon cycle.

The three choices that could have affected the environment are as follows:

The environment may be defined as anything which is present in the surroundings of living organisms. This environment basically has two types of factors biotic and abiotic factors.

In the above three choices, building a green environment has a positive effect on the environment. It may also affect living organisms positively. While the rest of the two may stimulate a negative impact on the environment by increasing the levels of carbon dioxide by liberating emission and non-biodegradable plastics.

Therefore, the three choices that could have affected the environment are well mentioned above.

Answer:

Disaccharide

Explanation:

It is a disaccharide, a molecule composed of two monosaccharides: glucose and fructose. Sucrose is produced naturally in plants, from which table sugar is refined. It has the molecular formula C12H22011.

Answer:

table sugar is example of glucose. It has the molecular formula C12H22O11.

Answer:

C. Simple diffusion

Explanation:

Simple diffusion from a high to low concentration is the most direct method that ions or molecules can move across a cell membrane.

Through this method, no proteins are required for transport, and no energy is used.

The ion or molecule being transported directly moves across the cell membrane, without any other factors involved.

So, the correct answer is C. Simple diffusion

Answer:

This allele has not been eliminated by natural selection because it may confer an adaptive advantage for particular environmental conditions  

Mice and rats are opportunistic species. These species can rapidly adapt to different environmental conditions, while cheetahs are unable to adapt to changing environments.  

Explanation:

An allele is a gene variant that may be beneficial, neutral, or deleterious for a particular environment. Different alleles are not eliminated by natural selection against other alleles (even when a priori seem to be deleterious) because they confer a selective advantage in a given environment. For example, the allele for sickle cell anemia is caused by a point mutation which is lethal in homo-zygous individuals, but heterozygous individuals are less likely to die of malaria, thereby this allele has been positively selected in geographic areas where malaria is an endemic disease. Moreover, mice and rats are opportunistic species, i.e., they are species that rapidly adapt to varied living conditions. These species are characterized to have high growth rates and produce many offspring. On the other hand, the cheetah is a highly specialized species that is unable to adapt to changing environments. In consequence, cheetah populations are more prone to become extinct than rat and mice populations.

Rough endoplasmic reticulum

Answer:

Rough endoplasmic reticulum is among the organelles that are found in eukaryotic cells. The reason as to why it is called rough is because it has ribosomes attached to its surface. Its main function is to produce proteins.

Explanation:

Answer:  A controlled variable or constant variable is a variable that does not change during an experiment.

Explanation:

A controlled variable or constant variable is one which the researcher holds constant (controls) during an experiment. It is also known as a constant variable or simply as a control.The control variable is not part of an experiment itself it is neither the independent nor dependent variable but it is important because it can have an effect on the results gotten.

example of a controlled variable is temperature.

Answer:

Tallness.

Explanation:

Tallness is the critter trait that is affected by an environmental factor, such as light, temperature, or  diet because the organism remains short if they are not getting food properly as well as temperature. Food provides essential nutrients that contribute in the growth of organism. Suitable temperature of the body allows the different functions in the body to be done which directly affects the growth of the body and the organism becomes taller.

Answer:

EeWw

Explanation:

The allele for the earlobe is depicted as e while that of the hairline is w.

A parent that is homzygous recessive for earlobes (ee) and homzygous dominant for hairline (WW) would have the genotype eeWW.

The other parent that is homzygous dominant for unattached earlobes and homzygous recessive for hairline would have the genotype EEww

eeWW    x    EEww

During meiosis, each genotype will form gametes.

eeWW: eW, eW, eW, eW

EEww: Ew, Ew, Ew, Ew

These gametes will randomly unite during fertilization to produce offspring. Since the same gametes are formed by each parent:

   eW   x   Ew

offspring

100% EeWw (see the attached image for the Punnet's square)

The genotype of all the children would be EeWw and would phenotypically be with unattached earlobes and dominant hairline.

Answer:

The correct answer is - damaged, effector organ, neurilemma, damage, distance, cell body, decreased.

Explanation:

PNS axons are prone to cuts, and other types of injuries. A damaged axon can regenerate if the effector organ remains intact and a critical amount of neurilemma is found.

The degree of success of these axons regeneration depends upon factors that are (1) the amount of damage, and (2) the distance between the site of the damaged axon and the cell body it innervates The possibility of repair is reduced with an increase in either of these two factors. Neurolemmocytes play an active role in regeneration

Chitin.

Explanation:

The structure that is not a component of wall of sponges is Chitin. Their body comprise of calcareous or siliceous spicules or protein spongin fibres. Choanocytes are the distinctive cells located in the interior body walls of sponges. Sponges are similar to other animals in many characteristics such as they are multicellular, heterotrophic, lack cell walls and produce sperm cells in order to produce offspring sexually and also different from animals due to lack of tissues and organs.

Explanation:

The purple non-sulfur bacteria which depends on light produces organic food  just like plants through the process of photosynthesis. The purple non-sulfur bacteria uses carbondioxide and water with sunlight produces oxygen and glucose which is an organic compound. So that's why purple non-sulfur bacteria is also known as phototrophic means organism that produces their own food through photosynthesis.

Answer:

Climate change is the global phenomenon of climate transformation characterized by the changes in the usual climate of the planet (regarding temperature, precipitation, and wind) that are especially caused by human activities

Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming. Humanity’s increased use of fossil fuels – such as coal, oil and gas to generate electricity, run cars and other forms of transport, and power manufacturing and industry

Deforestation – because living trees absorb and store carbon dioxide

Increasingly intensive agriculture – which emits greenhouse gases like methane and nitrous oxide

Answer:

6.25%

Explanation:

Find the number of different gametes that can be produced

number of gametes produced = 2^n

n is the number of allele pairs that are heterozygous

there are 4 heterozygous allele pairs, these are: Aa, Cc, Ee and Ff

2^4 = 16

abCdeF is one of the 16 genotypes that could be produced

to find the percentage, divide 1 and 16 and multiply by 100

1 ÷ 16 = 0.0625

0.0625 × 100 = 6.25
