Answer 1

Answer:

D / D / D / B / C

Explanation:

I just took the quick check myself, got all of them right :)

1 ) Top predators do not increase the number of prey, neither do they create imbalance or increase the food for other predator species. This is common knowledge, so ruling those out you are left with D. As they do in fact maintain the rest of the food chains populations.

2) A top predator in the ocean is a shark. Of course some might mistake a small whale to be a top predator, but sharks are actually known to hunt whales- the small ones anyway. A sea lion fish or a bird wouldn't exactly be a candidate for the top of the food chain either.

3) During seasonal flooding, to an area such as a river, water gets added to the existing pool, and many biotics and abiotics take this to their advantage. As a result- biodiversity actually increases during these times, but once season flooding is over it goes back to being the same.

4) The impact difference of seasonal flooding from damming a river is actually quite big. Seasonal flooding is.. well.. seasonal.. while damming for the most part is permanent, or will be there for much longer time span than season flooding is. Seasonal flooding increases biodiversity, but damming does not. This is becuase of the long term increase of water, the environment has to readapt, as plants that were once there drowned, and the known species most likely ran off to find better environment. Here it takes a while but eventually new abiotic and biotic species adapt and reclaim the dammed area of the environment.

5) Yes, a long term increase in the average temperature would disturb the ecosystem. Even if it's for a little bit, it's still something the environment wouldn't be used to, meaning the plants and animals there would have to learn to adapt for the time being- even if its temporary.

Answer 2

1: It maintains other populations

2: A shark

3: The biodiversity of the area increases

4: Seasonal flooding does not impact biodiversity for as long term as damming.

5: Yes, because such a change could have a large-scale impact on wildlife.

Explanation:

Los antibióticos actúan sobre las bacterias ya sea matandolas o evitando que la población de un determinado tipo de bacterias se reproduzca haciendo que los mecanismos de defensas presentes en nuestro cuerpo puedan actuar sobre las bacterias ya existentes.

Los antibióticos pueden ser específicos para cierto tipo de bacterias o actuar de forma general afectando a varios tipos de bacterias presentes en nuestro organismo. Si se atacan bacterias que están normalmente en nuestro cuerpo por acción indiscriminada del antibiótico, nuestro organismo sufre un desequilibrio ya que las bacterias que tendrían que estar presentes para procesar ciertos elementos o realizar otras funciones no están.

Which of these processes does not occur as part of the cell cycle in animal cells?

1) Mitochondrial DNA is released into the cytoplasm

2) Two identical copies of chromosomes are produced

3) Cell growth and mRNA synthesis occur

4) Nuclear DNA is replicated

Answers

The cell cycle is an essential process of growth and function. It has many phases which divide the genetic material and the cytoplasmic organelle equally into new cells. The cell cycle is crucial for survival.

Option 1) Mitochondrial DNA released into the cytoplasm is the process that does not occur in the animal cell cycle.

Cell cycle steps in animals can be explained as:

In the animal cell cycle during the synthesis step, the genetic material replicates to produce two identical chromosomal groups.

The cell divides to grow and the processes of central dogma including mRNA synthesis and protein formation occur.

Mitochondrial DNA does not get released in the cytoplasm but remains sustained in the mitochondria structure.

Therefore, mitochondrial DNA is not discharged into the cytoplasm.

Answers

Answer:

D

Explanation:

It doesn’t matter where u take ur observations

The statement which is not important in an experiment is to perform the experiment in the same location where the observations were done in. Thus, the correct option is D.

What is an Experiment?

An experiment may be defined as a scientific procedure that should be followed in order to estimate, discover, and observe a given testable hypothesis to demonstrate a valid and accurate conclusion.

The Scientific experiments should also be performed under a controlled environment where all data must be recorded and keep them consistently.

In demonstrating the valid outcome of any scientific experiment, it is required to alter only one source of variable and estimate the value of others on the basis of it.

Therefore, the statement which is not important in an experiment is to perform the experiment in the same location where the observations were done in. Thus, the correct option is D.

Name the 6 roles of proteins in the body.

Answers

Answer: 1. Repair and Maintenance

Protein is termed the building block of the body. It is called this because protein is vital in the maintenance of body tissue, including development and repair. Hair, skin, eyes, muscles and organs are all made from protein.

2. Energy

Protein is a major source of energy. If you consume more protein than you need for body tissue maintenance and other necessary functions, your body will use it for energy. If it is not needed due to sufficient intake of other energy sources such as carbohydrates, the protein will be used to create fat and becomes part of fat cells.

3. Hormones

Protein is involved in the creation of some hormones. These substances help control body functions that involve the interaction of several organs. Insulin, a small protein, is an example of a hormone that regulates blood sugar. It involves the interaction of organs such as the pancreas and the liver. Secretin, is another example of a protein hormone. This substance assists in the digestive process by stimulating the pancreas and the intestine to create necessary digestive juices.

4. Enzymes

Enzymes are proteins that increase the rate of chemical reactions in the body. In fact, most of the necessary chemical reactions in the body would not efficiently proceed without enzymes. For example, one type of enzyme functions as an aid in digesting large protein, carbohydrate and fat molecules into smaller molecules, while another assists in the creation of DNA.

5. Transportation and Storage of Molecules

Protein is a major element in transportation of certain molecules. For example, hemoglobin is a protein that transports oxygen throughout the body. Protein is also sometimes used to store certain molecules. Ferritin is an example of a protein that combines with iron for storage in the liver.

6. Antibodies

Protein forms antibodies that help prevent infection, illness and disease. These proteins identify and assist in destroying antigens such as bacteria and viruses. They often work in conjunction with the other immune system cells. For example, these antibodies identify and then surround antigens in order to keep them contained until they can be destroyed by white blood cells.

How does the electron transport chain deal with the electrons removed from sugar molecules?

Answers

Answer:

Explanation:

The electron transport chain is the portion of aerobic respiration that uses free oxygen as the final electron acceptor of the electrons removed from the intermediate compounds in glucose catabolism. The electron transport chain is composed of four large, multiprotein complexes embedded in the inner mitochondrial membrane and two small diffusible electron carriers shuttling electrons between them.

The electrons passing through the electron transport chain gradually lose energy, High-energy electrons donated to the chain by either NADH or FADH2 complete the chain, as low-energy electrons reduce oxygen molecules and form water.

These same molecules can serve as energy sources for the glucose pathways.
