Control group: volunteer stationary bike riders in a pollution-free chamber

Experimental group: volunteer stationary bike riders in a chamber filled with air pollutants common to Los Angeles

Independent variable: exposure to air pollution

Dependent variable: The heart rates (physical fitness) of the volunteer riders.

Explanation:

In a scientific experiment, data is compared between the control group and experimental group to ascertain the effect of the independent variable on the dependent variable. A control group is the group in an experiment that is not treated with the independent variable i.e. the independent variable is controlled while the experimental group is the group that is treated with an independent variable.

N.B: The independent variable is the variable controlled by the experimenter in order to influence the dependent variable (measurable outcome).

In this experiment, the independent variable is the AIR POLLUTION the volunteer riders are exposed to while the dependent variable is the PHYSICAL FITNESS/ HEART RATES of the volunteer riders, which is dependent on the exposure to air pollution (independent variable).

The control group in this experiment is the volunteer riders placed in a POLLUTION-FREE CHAMBER where the independent variable cannot influence or have any effect on the measurable variable (dependent). The experimental group is the volunteer riders placed in a CHAMBER FILLED WITH AIR POLLUTANTS. The independent variable (air pollution) has been changed in the experimental group.

The DNA is primarily made up of 3 components, namely:

The DNA consists of two strands that are linked together through a hydrogen bond. They are usually found primarily in the nucleus and organelles like mitochondrion and chloroplast of eukaryotic organisms. However, due to the absence of nucleus in prokaryotic organisms, DNA is found within the cytoplasm.

Hence, the correct properties of DNA according to the question are:

Answer:

The correct answer is - 0.72 pg.

Explanation:

A we know that, genetic material present in one primary spermatocyte divides in between four sperm cells that means that each sperm cell has 25 percent of DNA or genetic material of the primary spermatocyte.

Given:

1 sperm cell = 0.18 nuclear DNA

So,[tex]DNA content of one sperm cell = \frac{\text DNA content of primary spermatocyte}{4}[/tex]

Answer:

An ecosystem is, by nature, a functional whole of organisms and inanimate environmental factors in a coherent area, which includes both natural and non-natural objects (animals, plants, rocks, etc.) in a certain limited area.

Thus, there are ecosystems that have greater degrees of diversity than others, depending on the different variants of living beings and plants that compose it. The more diverse an ecosystem, the more complex it will be considered. Thus, the more complex and varied it is in terms of its composition, the more sustainable it will be. This is so because, given the differences between the different members of the ecosystem, there is not such a great competition for the resources of the living space, since each species has a different interest and consumes different resources. In this way, a balance is generated by which the different members of the ecosystem consume the resources necessary for their subsistence without depleting the production capacity of the ecosystem.

C

Explanation:

Answer:

guanine

Explanation:

IN DNA guanine make a base pair with cytosine and thymine make a base pair with adenine

In DNA, cytosine binds with guanine in the opposite strand. Therefore, option "B" is correct.

There are five types of nucleotide bases adenine, cytosine, guanine, thymidine, and uracil. These divide into two classes of nucleotides pyrimidine and purine nucleotide bases.  Pyrimidines are uracil, thymine, and cytosine whereas adenine and guanine are purines.

DNA consists of adenine, cytosine, guanine, and thymidine. In RNA, adenine, cytosine, and guanine are present but thymine is replaced by uracil. Pyrimidine always binds with the purines through hydrogen bonding. Adenine binds with thymine. Cytosine binds with guanine. But when adenine pairs with uracil in RNA.

Therefore, nucleotides are the functional units of DNA.

Answer:

helps us understand more about the universe

Answer:

Explanation:

The subject of detrimental environmental change has received much attention in the news media for some time. Scientists, policy makers, and the public have become increasingly concerned about the threat that such change, if it continues unabated, poses for the future. Growing numbers of scientists from a variety of disciplines have been systematically studying specific aspects of this change and attempting to identify effective strategies for preventing or mitigating potentially catastrophic effects.

the 5 factors are

*Dimensions of the Problem *

Some earth and atmospheric scientists have been documenting an increased concentration of carbon dioxide and other "greenhouse gases" in the atmosphere and have been attempting to better understand how a continuing accumulation will affect the future world climate (Houghton and Woodwell, 1989; National Research Council, 1983). Others have been studying

2)Behavioral Causes of Environmental Change

Many of the most readily identified causes of these changes are human activities. Major contributors to the accumulation of greenhouse gases in the atmosphere include the burning of fossil fuels for heating and energy generation and the use of chlorofluorocarbons (CFCs) as coolants and aerosols. The burning of fossil fuels is also a major cause of acid rain, which is formed when airborne sulfur dioxide and nitrogen oxides combine with water vapor. Air pollutants include ozone, carbon monoxide, lead, sulfur dioxide, nitrogen dioxide, and particulates—all by-products of industrial and energy-generation processes. Stratospheric ozone thinning is believed to be a direct consequence of the accumulation of CFCs in the upper atmosphere.

3}POSSIBLE APPROACHES TO THE PROBLEM

The problem of detrimental environmental change is broad in scope and considerably beyond the ability of the human factors research community to solve. But human factors researchers can contribute greatly by working toward the goal of finding effective ways to modify, or mitigate the effects of, the human behavior that is a major cause of such change. It is useful to make a distinction between attempting to modify behavior directly and attempting to modify it indirectly by changing technology so that its use will be less detrimental to the environment

4}Direct Behavioral Change

Possible ways to directly induce behavioral change include the use of coercion (legislation and regulation, backed up with the threat of civil or criminal sanctions), incentives (tax and other monetary incentives, public recognition, and awards), education (making people aware of problems and what can be done about them), and persuasion (appeals to moral responsibility or altruism—or the possibility of embarrassment or shame). All of these methods have been tried, many times in some cases, and in numerous variations.

5}Changing Technology

One may work on the goal of water conservation by trying to persuade people to use less water when taking showers by, say, taking shorter showers, keeping the tap less than wide open, or keeping the tap closed while actually washing. Alternatively, or in conjunction with efforts to change behavior, one can attempt to design shower heads that automatically conserve water by limiting the flow when the tap is fully open but that still provide adequate water for showering. Ideally, one would like a water-miser shower head whose spray is preferred by users, who then will be motivated to use this head whether or not they are concerned about environmental change.

Answer:

The answer is e

Explanation:

Answer:

Explanation:

This is due to the fact that water has  high specific heath capacity,which makes it to accommodate large amount of heat energy produced by the catabolic reactions which liberated heat.

General, the amount of heat energy needed to raise the temperature of a particular substance over a given amount is called the specific  heat capacity of that substance. Therefore for water, the amount of heat energy needed to raise the mass of 1kg of water by 1 degree is called the specific heat capacity of water.

Since large hydrogen bonds  held water molecules together,it takes a long time of heat energy to break these bonds free to raise the temperature of water.Hence, water in living cells is able to accommodate large amount of heat energy to stabilise the temperate of the cells.

Answer:

B

Explanation:

The net movements of water from the region of higher water potential  to the region of low water potential through  a selectively permeable membrane is osmosis. It is a form of diffusion which involves the transport of water molecules.

In this present scenario  water molecules  pass through the selectively permeable membrane from higher water potential in the body, to lower water potential but high solute potential (Epsom salts). The later is called an hypertonic solution,this is because it has higher solute potential ,thus higher salt concentration than the surrounding medium,therefore water pass by osmosis into the Epsom salts.

If one is placed in this solution,the cells shrink as they lose water to the more concentrated Epsom.(hypertonic solution)

However, the body homeostatic mechanism through the kidney  ensure re-absorption of fluid back to the body from the DCT  and CT, via  anti diuretic hormone to preserve the cell and the person.

Answer: Leaving diseased trees to infect other trees

Explanation:

Sustainable logging refers to methods that balance the needs of people with the needs of the environment such that forests are protected in the long term.

These include selectively cutting trees so that others can remain and thrive, replanting new trees and harvesting in such a way that room for continuity in terms of seed dispersal is possible.

When a tree is infected with disease however, leaving it could be detrimental to the survival of trees in the area as the infected tree could infect others. When a diseased tree is noticed, swift action should be taken to mitigate the threat by either treating the tree or if it is too infected, cutting it down.
