Why is a food web a better representation of relationships within an ecosystem than a food chain? A. A food web shows that most organisms consume and are consumed by more than one organism. B. A food chain shows that most organisms consume and are consumed by more than one organism. C. A food chain shows only a single pathway of energy. D. A food web shows a single pathway of energy flow through the ecosystem.

Answers

Answer 1

Answer: A.

a food chain is almost never possible, as in any ecosystem most species are consumed by more than one species of a higher trophic level.

Answer 2

Answer: c. a food chain shows only a single pathway of energy

How do the products and reactants of a chemical change compare?The mass of the products is greater than the mass of the reactants because energy is taken in by the reaction. The mass of the products equals the mass of the reactants because the same matter is present. The mass of the products equals the mass of the reactants because there is no energy involved in the reaction. The mass of the products is less than the mass of the reactants because energy is given off by the reaction.

Select all that apply.Which fungi are used in medicine?

yeast
penicillium
aspergillus
Rhizopus stolonifera

Answers

The correct answer is:

Penicillium

Aspergillus

The lesson states:

If you've ever heard of or taken penicillin to fight off an infection, you can thank a member of the imperfect fungi called penicillium. Some mold species of penicillium are also important in the flavoring and aging of cheese. Roquefort and Camembert cheese owe their distinctive flavors to these fungi. Aspergillus is an imperfect fungus that is found on decaying food. It also contributes to the production of organic acids like citric acid. Both penicillium and aspergillus produce enzymes that are purified and used in various industrial compounds and in medicine.

Introducing the gene for bovine growth hormone into the eggs of pigs is an example of a process called

Answers

The answer is germline gene therapy.

The gene therapy is the process which aim is to introduce the gene for the desired protein into cells in order to make desired protein or to compensate for abnormal genes. If the gene for the desired protein is introduced into the gamete cells (eggs or sperms), then the gene therapy is called germline. The example is introducing the gene for bovine growth hormone into the eggs of pigs. This way the change is heritable and can be passed down to the next generation.

Which statement explains the effect if an inhibitor on an enzyme

Answers

Answer:

The correct answer is B) a substrate will be unable to attach to the enzyme.

Explanation:

The enzyme binds to the substrate binds to proceed with the reaction. Enzyme attached to the active binding site of the substrate and form an enzyme-substrate complex to minimize the threshold of the reaction.

Inhibitor competes with the enzyme for the active binding site. Instead of the enzyme, the inhibitor binds with it and stops the reaction.

Enzyme Inhibitors are substances that change the speed of the enzyme by slowing it down or stopping it. You didn't include the answer choices but I would say that it would either be slowed down or stopped as an effect.

Which statement accurately describes how identification of individuals through the use of genetic engineering is possible? A. The DNA in mitochondria is passed from mother to child in the nucleus of a cell.
B. The Y chromosome doesn't experience crossing-over.
C. The mitochondria DNA in a mother and her offspring vary greatly.
D. The X chromosome can only be passed from a father to his son.

Answers

The identification of an individual by the means of genetic engineering is possible because the Y chromosomes in the males does not experience any crossing-over as there is only a single Y chromosome present in a human male.

The mitochondrial DNA is passed from the mother to child in the cytoplasm of the cell, and it is passed on without any changes. The X chromosome is can be passed from a mother to her son as he will receive Y chromosome from his father.

Hence, the correct answer is 'Option B - The Y chromosome does not experience crossing over'.

A. The DNA in mitochondria is passed from mother to child in the nucleus of a cell.

A benefit of genetic engineering is the production of valuable proteins that have helped in managing of illness in human beings. Bacteria were genetically engineered to produce proteins of medical importance. One example of such a protein is human insulin which is given the name humulin and is made using E. coli bacteria.Earlier, insulin from pig cells was used to treat patients with diabetes but many of them could not tolerate it because it has a slightly different arrangement of amino acids from that of humans and so the human body rejects it. Humulin is tolerated by the human body and so many patients are now using it to lead normal lives.
