Answers

Answer 1

Answer: The pattern of disproportionate dumping of toxic waste and other forms of pollution in neighborhoods where the poor and people of color live is called Environmental Racism.
This involves the placement of low-income or minority communities in the proximity of environmentally hazardous or degraded environments, such as toxic waste, pollution and urban decay. The socially marginalized racial minority communities are subjected to disproportionate exposure of pollutants and/or the denial of access to sources of ecological benefits such as clean water, air, and natural resources.

Which base is found in RNA but NOT in DNA? A) adenine B) cytosine C) thymine D) uracil

Answers

Its Uracil.Uracil is energetically less expensive to produce than thymine, which may account for its use in RNA. In DNA, however, uracil is readily produced by chemical degradation of cytosine, so having thymine as the normal base makes detection and repair of such incipient mutations more efficient

The DNA nucleotide bases include adenine, cytosine, guanine and thymine. The RNAnucleotide bases include adenine, uracil, guanine and cytostine.

Why do we get ill when we get stressed?

Answers

When your body is stressed you are constantly in the fight or flight mode. Your heart beat is higher, blood pressure is up and constant alertness is given full attention to your bodies defenses. Ther are a lot of flowing hormones to be able to use all of your strenght and more to survive. When this continues for long periods of time you dont sleep, eat and think properly and your body's immune system is weakened and you get sick easier.

When our body temperature rises above 37°c or 98°f, a negative feedback mechanism will be triggered to lower the body temperature. as a result, our sweat glands release sweat to cool the body temperature. what part of the negative feedback mechanism is the sweat gland?

Answers

corrective mechanism.

Daphnia are freshwater organisms sometimes referred to as “water fleas.” Design an experiment thatcould be used to test the effects of temperature on the size of a daphnia population. In your
experimental design, be sure to:
• state a hypothesis to be tested
• describe how the control group will be treated differently from the experimental group
• identify the independent variable in the experiment
• identify the type of data that will be collected

Answers

An experiment is where scientific data is gathered and analysed to form inferences. Moreover, we can establish a testing ground on the daphnia population, let say by embryology. Hence, we can observe ina controlled manner how temperature influences the growth and formation of offspring by mothers of the daphnia population considering that offspring can contribute to population growth.

Answer

• state a hypothesis to be tested

Development rate increases faster with temperature that growth rate

• describe how the control group will be treated differently from the experimental group

The control group will be raised at 8 different temperatures to assess their size at maturity, and their asymptotic size.

• identify the independent variable in the experiment

3 clonal lines that differ in asymptotic size and growth rate.

• identify the type of data that will be collected

Measurements of the individual length of Daphnia

Explanation

In this experiment, the temperature-size rile(TSR) was utilized where it will be found that responses on temperature size observed at maturity is different from that manifested at asymptotic size. It will be observed that thermal shift in resources allocation may completely or partly result to a thermal plasticity in maturity size. Moreover, it will be seen that thermal plasticity in asymptotic size is controlled by temperature related challenges.

What are the behavioral adaptations of a tiger?

Answers

1. Some hunt alone, since it is easier to surprise their prey, and some prey in pacts,to kill their prey faster.
2. They scratch their foreclaws on treetrunks to sharpen their foreclaws and mark their territory.
3. They are isolated so they do not socialize with other tigers, unless they are hungry.
