Answer:

When the body is supported by a wall then it can move in a position counter gravity. The gravity tries to pull the body down and the body responds to it with a slight delay because of wall support.

Explanation:

The body is lifted in upright position with the help of feet. The body rises but after few minutes the gravitational force creates pressure on the body and the body comes down to a natural state. Similarly if the open door is used to perform counter gravity activities then the body will stay for a lesser period in a state because of opened door instead of firm wall support.

Answer:

In artificial selection, humans have the capacity to influence certain characteristics of organisms by selective breeding. One can choose desired parental traits determined by genes, which are then passed on to offspring.

Explanation: I hope I could help

Answer:

1.) The solute molecules will not move between the two sides because the membrane does not have large enough spaces for the molecules to move through. The water molecules will move to the right side because water moves to places of a higher solute concentration.

2.) The right side represents high concentration because it contains the majority of the solute molecules.

3.) The left side represents low concentration because it contains a small amount of solute molecules compared to the right side.

Answer:

Matter can cycle through the biosphere because biological systems do not use up matter, they transform it. The matter is assembled into living tissue or passed out of the body as waste products. ... Simply put, biogeochemical cycles pass the same molecules around again and again within the biosphere.

Answer:

Inhibit control over ions.

Explanation:

The immediate effect of the neurotoxin on the postsynaptic neuron is to inhibit control over ion concentrations across the cell membrane. The neurotoxin blocks nervous transmission at synapses which prevents the vesicles containing the neurotransmitter from fusing with the presynaptic membrane so the information does not transfer from one neuron to another and as a result the body is present at constant relaxation mode. The membrane potential of postsynaptic neuron will decrease due to neurotoxin.

Answer:

Greatly affect the population.

Explanation:

Environment and weather of a country greatly affect the population and people of a region because good environment with all resources and suitable weather attract people of other regions toward itself. If the location has plenty of water, vegetation, flat geography and food etc, the people settled in this location and increase occur in population whereas if the area doesn't have any natural resources so people migrate from that area.

Answer:

Explanation:

During melting, energy goes exclusively to changing the phase of a substance; it does not go into changing the temperature of a substance. Hence melting is an isothermal process because a substance stays at the same temperature.

Answer:

Explanation:

The double-stranded DNA molecule has the  potential to store genetic information in either strand, although in  most organisms only one strand is used to encode any particular gene.  

The template strand is the non-coding strand. The coding strand of DNA is the non-template (mRNA-like) strand (see attachment).

Thus, genetic  information is expressed by transcription of the non-coding (template) strand  of DNA, which produces an mRNA molecule that has the same sequence  as the coding strand of DNA. Therefore, if a mRNA is transcribed from the non-template strand, the genetic information will not be contained in that strand and it would not produce a correct protein.

Answer:

a. What is the significance of the rainfall? These bacteria resist desiccation, and its dispersion is favored by winds. A decrease in rainfall means a dryer environment, which the bacteria can resist and makes it easier for the cell to be carried somewhere else by winds.  

b. The etiologic agent of the disease is Coxiella burnetii

c. This is an example of  a zoonosis  

Explanation:

Q fiber Pneumonia is a zoonosis world-widely distributed and of global importance, which etiologic agent is Coxiella bunetti.

Populations in contact with goats, sheep, and cattle, use to have a positive result for antibodies against Coxiella burnetii. This bacteria is transmitted to humans orally and by inhalation. The microorganisms resist extreme conditions and are highly infectious. The inhalation of only one cell can produce an important infection in the host. It resists desiccation and any other environmental degradation. They can persist for several months and be transported by winds to farther places. This makes it even more difficult to determine the epidemiologic origin.

Answer:

A) chemical splashes

C)UV exposure when using UV radiation in the laboratory

Explanation:

Goggles as well as safety glasses can be regarded as a form of protective eyewear which helps to enclose and protect every area of the eyes to prevent particulates, chemicals as well as water from striking the eyes in the laboratory or in the field. Eyewear is used to prevent chemical splash during experiment, it can prevent exposure of UV radiation from entering the eye in the laboratory.

In order to protect our eyes using

Goggles or appropriate safety glasses, we must take this into consideration.

✓protective eyewear must be put on when required

✓ check the goggles to ensure its in good condition before using it and after using it.

✓ make sure the eyewear is fitted properly.

Answer:

Solar panels can generate electricity just about anywhere on Earth, but some areas receive more sunlight than others, and as such, have a higher solar energy potential. The following map, prepared by Solargis, shows areas with the highest PV production potential.

Answer:

Differential reproduction is called the one that occurs as a result of the differences between the individuals that make up a society or sample, where it is those with comparative advantages who manage to reproduce, while those who do not have said advantages tend to die out. It is, in short, a practical application of Charles Darwin's theory of natural selection.

Thus, if there is an overpopulation of a certain species, a series of effects will occur (such as the scarcity of resources, the lack of living space, etc.) that will tend to gradually decrease the population to return to an ideal number of individuals. In this aspect, differential reproduction will be applied, being able to reproduce those that have comparative advantages over the rest, which will inevitably become extinct.

Answer:

Yes, the experiment will work.

Explanation:

The reason behind this is that plasmids are well known to be DNA vector carriers. These plasmids have the ability to bring about changes in DNA fragments into various microorganisms and reveal them. The two plasmids compose of the same genomic marker such as the antibiotic resistance gene found in URA3. However, plasmids are most commonly found in bacteria, but also in eukaryotic cells. Oftentimes, the gene composition in the plasmids enhances the bacteria with a vantage edge such as antibiotic resistance.

Hence, it is obvious that in both, the molecular regulation in terms of expression of genes is alike in properties. Similarly, the numbers of copies and molecular weight are also the same.

We can thereby conclude that, provided that there is a proper restriction site, another host that is up to standard for plasmid can be replaced for each other.

Explanation:

Answer:true

Explanation:

Answer: Yea it’s True

Explanation:

Answer:

Genes that express 50% of recombination frequency or more are not linked genes. They might be in different chromosomes or located in the same one, but too far from each other.    

Explanation:

Genes are physically located in chromosomes. Many genes segregate independently after crossing-over because they are located far away from each other. But some other genes are too close, and they do not segregate independently. These are the linked genes that do not exhibit an independent distribution, and they inherit together more frequently.

We need to know that 1% of recombination frequency = 1 map unit = 1cm. And that the maximum recombination frequency is always 50%.

When the recombination frequency is inferior to 50%, genes are linked. If it is equal or superior, they are not linked. Genes are located far enough from each other to assort independently.

Genes that express 50% of recombination frequency or more are not linked genes. They might be in different chromosomes or located in the same one, but too far from each other.

Answer:

Yes, they would be able to produce weak muscled guinea pigs

Please see details below

Explanation:

This question involves a single gene coding for muscle size in guinea pigs. The allele for giant muscles (G) is incompletely dominant over the allele for regular muscles (R). This means that a third intermediate phenotype (weak muscles) is produced in a heterozygous state.

According to this question, a guinea pig with giant muscles (GG) is bred with a guinea pig with regular muscles (RR). The following gametes will be produced by each parent:

GG - G and G

RR - R and R

Using these gametes in a punnet square (see attached image), the following proportions of offsprings will be produced:

GR, GR, GR, and GR

This shows that all the offsprings (100%) have weak muscles, hence, YES is the answer to this question.
