Which of the following is not an example of energy transformations in an ecosystem?
a. sunlight driving photosynthesis in plants
b. herbivores feeding on plants
C. predators feeding on herbivores
d. none of the above

Answers

Answer:

d. none of the above

Explanation:

Energy, which refers to the ability to do work, can exist in different forms. The process of changing energy from one form to another is called TRANSFORMATION OF ENERGY. In an ecosystem, all organisms require energy in order to perform their life processes. They acquire these energy in different forms and convert it to a usable form by their cells (chemical energy) in ATP.

For example, solar energy in Sunlight is used by plants to drive their photosynthetic process and change it to chemical energy in glucose. Also, predators and herbivores feeding on herbivores and plants respectively converts one form of energy to another. Hence, all options are examples of energy transformation. None of the above is the correct answer.

Answer:

I think the correct answer is d ,

because all of them are an example of energy transforming in an ecosystem.

Which statement explains how a DNA mutation causes sickle-cell anemia?(1 point)

Answers

Answer:

DNA mutation causes a change in the amino acid sequence for hemoglobin, which causes a change in the shape

Explanation:

Sickle cell mutation is a mutation that affect the production of red blood cell that is needed for the transport of oxygen in the bloods stream.

sickle cell mutation is a result of change in the amino acid which are building blocks of the protein hemoglobin.

The protein is what gives red cells their color, it has two subunits. The alpha

and beta subunit. There is a change in the arrangements of amino acid sequence and that is the basis for the sickle cell shape, beta subunit has valine an amino acid at position 6 instead of the glutamic acid. This alteration results in sickle cell problems that occur in people.

Answer:

Explanation:

From the options:

The DNA mutation increases the number of amino acids in hemoglobin, which causes a change in the shape of red blood cells.

The DNA mutation causes a change in the amino acid sequence for hemoglobin, which causes a change in the shape of red blood cells.

The DNA mutation decreases the number of amino acids in hemoglobin, which causes a change in the shape of red blood cells.

O The DNA mutation prevents formation of hemoglobin, the absence of wirich causes a change in the shape of red blood cells.

The correct answer would be that "The DNA mutation causes a change in the amino acid sequence for hemoglobin, which causes a change in the shape of red blood cells. "

The sickle-cell anemia is caused by a change in the amino acid sequence of the hemoglobin - specifically, as a result of the substitution of the sixth amino acid, glutamic acid, by valine in the beta subunit of the proteins that make up the hemoglobin. A single base substitution causes glutamic acid to be changed to valine.

The normal hemoglobin is disc-shaped and is able to effectively carry oxygen in the blood, unlike the sickle-cell hemoglobin which has the sickle shape and is not able to effectively carry oxygen in the blood.

Answers

Let's list the given options alphabetically to choose the appropriate answer.

One reason cancer cells are easier to culture than normal cells extracted from an organism is that ________. Group of answer choices

A. cancer cells grow in a more regulated fashion.

B. cancer cells do not need to adhere to a substratum to grow.

C. nutrient requirements for cancer cells are precisely defined.

D. cancer cells are better models for demonstrating what happens in an intact organism

Answer:

B.

Explanation:

Cancer cells are easier to culture in comparison to normal cells because cancer cells do not need to adhere to a substratum to grow.

As cancer cells are uncontrolled growth of cells and they do not require any substratum to grow and can easily grow to a culture while a normal cell require optimal conditions to grow in a culture.

Hence, the correct option is "B".

What has a greater influence on protein levels? A. Protein degradation has a greater influence because they are denatured faster than the cell can produce them B. mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced C. mRNA destroyer concentration has a greater influence because mRNA is destroyed right after the proteins are produced D. Protein degradation has a greater influence because outside factors like antibiotics can cause it, and it is difficult to recover from

Answers

Answer: b

Explanation: i got the answer wrong and i’m looking at the results rn

Protein is being produced with the help of a process called translation in which mRNA gets translated to produce proteins. The translation is followed after the process of transcription of DNA to RNA.

The cause of the greater influence of protein levels has defined as follows:

The destruction of mRNA could greatly influence protein levels as mRNA is considered the source for proteins to get synthesized. This is because if mRNA gets destroyed, proteins would not have been produced at all. Thus, directly influences the levels of protein.

Thus, we can conclude that mRNA destroyer concentration has a greater influence because it is destroying mRNA before proteins can even be produced. Hence, option (b) is the correct answer.

Explanation:

Two groups of tomatoes were grown in the laboratory, one with humus added to the soil and the other a control without humus. The leaves of the plants grown without humus were yellowish (less green) compared with those of the plants grown in humus-enriched soil. The best explanation for this difference is that __________.

Answers

Answer:

The best explanation for this difference is that the humus contained micronutrients needed by the plants for the synthesis of chlorophyll, such as Manganese (Mn), Iron (Fe) and Copper (Cu).

Explanation:

Chlorosis is the yellowing of plant leaves, and this is due to the deficiency in the amount of chlorophyll contained in the plant leaves. Iron (Fe) is an essential micronutrient for the synthesis of chlorophyll, which is an enzyme-catalyzed reaction. Copper (Cu) is a component of most enzymes, while Manganese (Mn) is a cofactor, required for the activation of the enzymes that catalyze chlorophyll synthesis, hence deficiency of these nutrients will result in the development of chlorosis.

The plateau phase of population growth is best described as: A. The population stops growing because they moved into the plateau environment at this stage. B. The population pauses in its growth after a natural disaster before growing again. C. The population moves onto a large, raised, flat area called a plateau for protection from predator. D. The population stops growing because the environment has reached its carrying capacity.

Answers

Answer:

C. The population moves onto a large, raised, flat area called a plateau for protection from predator.

Explanation:

The plateau phase of population growth indicates that the population has stopped growing as the environment has reached its carrying capacity.

What is the plateau phase in population growth?

The population after going through different phases eventually reaches the plateau phase where the growth of the population stops or become constant. This is the outcome of the natality rate becoming equivalent to the mortality rate.

This occurs as the resources in the environment become less or scarce as well as there is an elevation in predators and parasites. These are considered as limiting factors to the growth of population. This makes the population number relatively stable. With the limitation in the resources it can be said that the environment has attained its carrying capacity.

Thus, the correct statement is option D.

How does Photosynthesis relate to Cellular (aerobic) Respiration?
A. Photosynthesis breaks down glucose, Respiration builds it.
B. They are equal but opposite reactions.
C. Photosynthesis is for plants, while Respiration is for animals.
D. They are not related.

Answers

Answer: photosynthesis breaks down glucose. Hope you understand

Explanation:

Photosynthesis is related to Cellular (aerobic) Respiration in that they are equal but opposite reactions and the correct option is option B.

Photosynthesis and cellular respiration are complementary processes that are crucial for the energy flow in ecosystems. In photosynthesis, plants and some bacteria use sunlight to convert carbon dioxide and water into glucose and oxygen. This process stores energy in the form of glucose.

In cellular respiration, organisms, including plants and animals, break down glucose and other organic molecules in the presence of oxygen to release energy for cellular activities. This process consumes glucose and oxygen and produces carbon dioxide and water as byproducts.

Photosynthesis and cellular respiration are interconnected through the exchange of products and reactants. The oxygen produced in photosynthesis is used in cellular respiration, while the carbon dioxide produced in cellular respiration is used in photosynthesis. As a result, they form a continuous cycle that maintains the balance of oxygen and carbon dioxide in the atmosphere and provides energy for living organisms.

Thus, the ideal selection is option B.

Illustrate the significance of membranes with the example of viruses

Answers

Answer:

Cell membrane encloses all the cell organelles.  In prokaryotes, membrane is absent and so membrane-bound cell organelles are also absent.

Significance of membrane can be explained with the help of viruses, as viruses lack cell membranes and that is why they require a host for living and uses the host's cell machinery to multiply.

Hence, cell membranes are important for living organisms to live and perform essential biological processes.

Studies of topsoil erosion on Iowa farmland shows that as much as 50 metric tons are lost per hectare during winter and spring rains. This loss is due to the loss of millimeters of soil from across the entire surface of the fields. Which type of erosion would this be?

Answers

Answer:

The type of erosion described in the question is called Water Erosion.

Explanation:

Note that the erosion is caused by winter and spring rains.

Water Erosion can happen when raindrops disintegrate the aggregates of the topsoil. The fragments collect into the soil pores and create a coagulating action which makes it difficult for the water to penetrate the soil. The rainwater having increasingly accumulated on the surface flows off along with the topsoil.

This type of erosion can be further aggravated if:

the rainfall is very heavy;the terrain has a steep gradient thus increasing the velocity of runoffthe soil type has a lower capacity to erosion

Pasteur's experiments proved that ________. Pasteur's experiments proved that ________. spontaneous generation can only occur if nutrient broth is left open to the environment cells cannot survive in swan-necked flasks preexisting cells present in the air can grow in sterilized nutrient broth sterilizing nutrient broth prevents spontaneous generation in order to grow, cells need to be supplied with oxygen

Answers

Answer:

preexisting cells present in the air can grow in sterilized nutrient broth

Explanation:

Spontaneous generation, which is the theory that life can arise from nonliving matter, has long been believed to be the way living organisms develop. However, in 1858, a French scientist called Louis Pasteur disproved the theory of spontaneous generation.

Louis Pasteur conducted an experiment to show that it is the existing microorganisms in air that causes life to grow and not the air itself. Pasteur made use of a swan-necked flask, which contained a sterilized (by boiling) broth. The swan-necked flask was designed in such a way that it would allow air to enter but trap any airborne microorganism, preventing them from reaching the broth.

Hence, if it were truly air and not existing life organisms that caused life growth, organisms should begin to grow from the broth. He conducted another experiment where be broke the neck of the flask to allow the entry of microorganisms into the sterilized broth and found out that growth of microorganisms occured on the broth.

Therefore, Pasteur, via his experiment was able to prove that preexisting cells present in the air can grow in sterilized nutrient broth if allowed entry but when there is no entry, there would be no life growth. This experiment disproved the theory of spontaneous generation.
