Food chains and food webs indicate the order in which organisms are eaten. What other information can food chains and food webs provide?

Answers

Answer 1

Answer: It can also show show the dry mass of living material at each stage of a food chain. Basically, how many organisms eat. For example:
1 oak tree → 1000 caterpillars → 100 shrews → 10 foxes
This is called pyramids of biomass.

Sickle-cell anemia is a genetically inherited disease. Homozygous individuals (SS) have normal blood cells that are easily infected with the malarial parasite. Thus, many of these individuals become ill and may die. Individuals homozygous for the sickle-cell trait (ss) have sickled red blood cells that readily collapse when deoxygenated. Although malaria cannot grow in these red blood cells, individuals often die because of the hemoglobin disorder. However, individuals with the heterozygous condition (Ss) have some sickling of red blood cells, but generally not enough to cause death. In addition, the heterozygotes tend to survive better than either of the homozygous conditions as they are resistant to malaria. If 16% of an African population is born with a severe form of sickle-cell anemia (ss), what percentage of the population will be heterozygous (Ss) for sickle-cell and therefore resistant to malaria?

A developer wants to turn part of a local woodlot into a new housing development. A vernal pool exists in the part of the woodlot marked for development. How might the developer’s plan affect the salamanders that live in the woodlot? Student Answer:
A The salamanders would have no water to drink.
B The salamanders would have no place to mate and lay their eggs.
The development would have no effect on the salamander population.
C The salamanders would not survive at all if the developer built houses in the woodlot.
I know its B but why would it be B?

Answers

The developer's plan would affect the salamanders that live in the woodlot by taking away their vernal pool, the lack of a vernal pool would mean that the salamanders would have no place to mate and lay their eggs. This would result in a drastic reduction of salamanders in the area.

Scientists have been experimenting with gene therapy, which often involves the use of bacteria or viruses to deliver new or modified genes to cells. These scientists believe gene therapy can be used to treat inherited diseases, but it is not yet in wide use even though many people have studied it. Which statement best describes gene therapy?

Answers

The correct answer should be something like: "Gene therapy involves the use of bacteria or viruses to deliver new or modified genes to cells". That is what can be concluded based on the paragraph you provided.

Answer:

Gene therapy is the introduction of normal genes into cells in place of missing or defective ones in order to correct genetic disorders. which often involves the use of bacteria or viruses to deliver new or modified genes to cells.

Researchers are testing several approaches to gene therapy, including:

Replacing a mutated gene that causes disease with a healthy copy of the gene.
Inactivating, or “knocking out,” a mutated gene that is functioning improperly.
Introducing a new gene into the body to help fight a disease.

You have two types of bread, three types of meat, and two types of cheese. How many different sandwiches can you make if each sandwich has one type of bread, one type of meat, and one type of cheese? 12 sandwiches
9 sandwiches
8 sandwiches
7 sandwiches
*This May seem very easy but i desperatley suck at math :(* ...?

Answers

Number of types of bread for making sandwich = 2
Number of types of meat for making sandwich = 3
Number of types of cheese for making sandwich = 2
Then
Number of different sandwiches that can be made = 2 * 3* 2
= 12 sandwiches

From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the first option.

All of Kay's brothers can swim. If the statement above is true, which of the following must also be true? A. If Fred cannot swim, then he is not Kay's brother. B. If Dave can swim, then he is not Kay's brother. C. If Walt can swim, then he is Kay's brother. D. If Pete is Kay's brother, then he cannot swim. E. If Mark is not Kay's brother, then he cannot swim.

Answers

Answer: A

Explanation:

A agrees with the original statement, so if Fred cannot swim it must be absolutely true that he is not one of Kay's brothers. Dave being able to swim would support that he is one of Kay's brothers, not refute it. Walt being able to swim does not automatically mean he is related to Kay, so that is not necessarily true. Pete being unable to swim also refutes the original statement. Mark not being Kay's brother has no correlation to his swimming ability.
