Answer: 4. Colchicine is a drug that prevents microtubule assembly, thereby disrupting microtubule-based functions.

Explanation:

Endocytosis can be defined as trapping of a substance from outside of the cell. Exocytosis can be defined as the process of fusion of the vesicles with the plasma membrane and excreting their contents outside the cell.

Colchicine is a drug that blocks the polymerization of microtubules in the cytoskeleton. This further prevents the transportation of vesicles out of the cell and in the cell. Thus this will prevent the exocytosis and endocytosis of the transport vesicles and will affect cellular metabolism.

Answer:

''If the old cells inoculated in chicken, it produces resistance in the chicken against new V. cholera cells.''

Explanation:

From the data provided by Louis Pasteur, we make a hypothesis i. e. ''If the old cells inoculated in chicken, it produces resistance in the chicken against new V. cholera cells.'' From these observation we can assume that by allowing old V. cholera cells to chicken, it did not cause any disease but make immunity against the new V. cholera cells which are more effective from old V. cholera cells.

Answer: Monosaccharides

Mono saccharides are the sugar molecules in which only single sugar compound is present. The correct answer is option D that is monosaccharides.

Glucose is the abundant form of sugar present in the nature.

Lactose is the milk sugar which is broken down by the enzyme called as lactase into two of the monosaccharide units called as glucose and the galactose. The process is called as digestion in which the complex substances are broken down into the simpler compounds for the sake of digestion.

Amino acids are the bio compounds in which they are both containing amine and the carboxylic acids which are later forms proteins and the peptides together form the proteinaceous structures.

Answer:

C) Scientists who have developed computers were improving on the work of scientists before them.

Answer:

The two genes are linked together

Explanation:

The conclusion that can be drawn about the arrangement of the genes on the chromosome in the Aa Bb parent is that the two genes are linked together. That is, they do not assort independently.

When two genes are linked together, the number of recombinant offspring would be more than the number of offspring with parental traits. The frequency of recombination would also not exceed 50%.

Recombination frequency = number of recombinant offspring/total number of offspring x 100%

Number of recombinant offspring = 45 + 45 = 90

Total number of offspring = 45 + 45 + 5 + 5 = 100

Recombination frequency = 90/100 x 100% = 10%

Hence, the two genes Aa and Bb are said to be linked together.

Explanation:

Viruses don't contain organelles.

The statement which is true with respect to the cell and viruses is as follows:

Thus, the correct option for this question is A.

A Cell may be defined as the basis structural and functional unit of life. All living organisms are made up of cells. Cells are required for organisms in order to accomplish their metabolic activities, growth, development, etc.

Most living cell significantly consists of cell organelles except for bacteria. Viruses are non-cellular. So, these do not have organelles. Viruses simply utilize the host machinery in order to multiple and reproduce.

Therefore, cells contain cell organelles while viruses do not contain organelles because they lack cells. Thus, the correct option for this question is A.

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: 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.

Answer:

700,000 nucleosomes and 1,400,000 H4 proteins

Explanation:

Number of base pairs for each nucleosome: 145 bp (core-DNA length) + 55 bp (linker-DNA length) = 200 bp

Genome size = 135 million bp of DNA = 135,000,000 bp >>

>> Number of nucleosomes in each nucleus = 135,000,000 / 200 = 700,000 nucleosomes

A nucleosome is composed of two copies of the H2A, H2B, H3, and H4 core histone proteins. In consequence, a nucleosome contains 2 two copies of the H4 histone protein >>

>> Number of H4 in each nucleus = 700,000 nucleosomes x 2 = 1,400,000 H4 proteins

Answer:

C

Explanation:

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.

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.
