An earthworm tunnel floods during a rainstorm, and the earthworm washes out onto the grass. According to Ch.27, what is the importance of the moisture from the tunnel to the earthworm?

Answers

Answer 1

Answer:

Answer and explanation;

The moisture pertains to its survival due to its respiratory surface. Such that too much water and the earthworm could die and too little water and the earthworm could dry up and die. Keeping their skin moist allows them to respire.
Earthworms are important as they plow the soil by tunneling through it, which provides the soil with passageways through which air and water can circulate.
The activity of the earthworms depends directly on soil moisture and temperature. They become active when soil thaws in the spring and move deeper in late summer as the soil dries.

Answer 2

Answer: The moisture from the tunnel to the earthworm is how they survive, too much moisture will kill them. And there abundant food source is located there.

Answers

Variable is the single factor tested in an experiment.

Variable is any factor or condition that can be tested, changed, or measured in an experiment. Scientific experiments have various kinds of variables. They include independent variables, dependent variables, constant variables and extraneous variables. The independent variable is the only factor that can be changed in a science experiment.

Detergents are compounds that dissolve lipids. If a cell were exposed to large concentrations of detergents, which cell part would likely suffer the greatest?

Answers

Ans.

Detergents are chemical compounds having both polar and non-polar components. They cause disruption of lipid molecules by breakdown bonds present between lipid molecules. In a cell, lipids are majorly present in cell membrane and membranes of internal cell organelles.

Thus, 'the cell part that would most likely suffer due to exposure to high concentration of lipids is cell membrane.'

Explanation:

A man who is an achondroplastic dwarf with normal vision marries a color-blind woman of normal height. The man's father was 6 feet tall, and both the woman's parents were of average height. Achondroplastic dwarfism is autosomal dominant, and red-green color blindness is X-linked recessive. ____ 15) How many of the couple's daughters might be expected to be color-blind dwarfs? A) all B) one out of four C) half D) none E) three out of four

Answers

Answer:

Half of the males are colorblind, dwarf and the other half colorblind, normal height.

Explanation:

The achondroplastic dwarf man with normal vision has a DdXY genotype. He marries a color-blind woman of normal height, so the hergenotype is ddX (c) X (c). All males will be colorblind as they inherit the X (c) chromosome from their mother. Half of them will be of normal height. So half of her boys will be colorblind and of normal height. To see how it works genetically, the cross is:

DdXY x ddX (c) X (c)

Your children have one of the four possible genotypes:

DdXX (c) (female, normal vision, colorblind carrier, dwarf)

DdX (c) Y (male, colorblind, dwarf)

ddXX (c) (woman, normal vision, color blindness carrier, normal height)

ddX (c) Y (male, colorblind, normal height)

One way that radioactive waste is treated is by burying it in repositories. The repositories are found only in states with very low populations. True or false

Answers

Answer: The given statement is False.

Repositories for the radioactive waste disposal are the the burial facilities, which are excavated in higher depth ( approximately 1000 feet below) having stable geologic environmental conditions.

They are used for burying radioactive waste so as to avoid the exposure of human population and environment with radioactive material ( which could be hazardous to lives as well as environment) present in the waste.

They could be built in any area that is geologically suitable for burying waste. This means that they have no relation with the size of population in that area.

Thus, the given statement is False.

False you can find them anywhere.
