Answer:

It occurs only in cells in the reproductive structures of organisms.

Explanation:

Meiosis only occurs in the reproductive cells, producing gametes with half of the genetic  information as the parent cell.

Meiosis can be best described as the event which occurs only in the cells which are the part of reproductive structures in an organism. Thus, the correct option is B.

Meiosis is a type of cell division which occurs in sexually reproducing organisms. It is also known as reductional division as in this division, the chromosomal number is reduced to half. This division is responsible for introducing genetic variations in a population.

Meiosis is a type of cell division which occurs in the sexually reproducing organisms. This division is responsible for reducing the number of chromosomes in the gametes or sex cells such as eggs and sperms by half. In humans, normal body cells or somatic cells are diploid in nature. These cells contain two sets of chromosomes i.e., one from each parent.

Therefore, the correct option is B.

The immune system has a vital role: It protects your body from harmful substances, germs and cell changes that could make you ill. It is made up of various organs, cells and proteins.

Answer:

I believe this is true.

Explanation:

Answer:

An area's latitude on the surface of the Earth affects the weather because it changes the intensity of the sun's light that the area receives. Things like mountains affect the weather by directing air currents, which can send storms to you, or keep them away. If you live in a place with lots of vegetation, it will be more humid, and warmer, because the plants retain the heat.

Answer:

The correct answer is option b.  "Helpful variations accumulate among surviving members of the species".

Explanation:

Natural selection is the most accepted theory of evolution, described by Charles Darwin in 1859. This theory explains that by the survival of the fittest, the helpful variations accumulate among surviving members of the species. The variations or mutations that are not helpful for the species are lost by predators and environmental factors, while the helpful variations remain in the surviving members, which leads to the species evolving to have improved characteristics.

Answer:

Heritability is a measure of how one person differs from the other based on their genetic make up. Differences in genes or their make up leads to differences in their traits or characteristics such as height, eye color, and intelligence. Genetics and its applications have a wide variety of applications serving the human mankind. This includes the detection of many diseases like cancer at early stages,treatment of diseases, forensic applications with DNA fingerprinting, Cross breeding in both plants and animals to obtain high quality products with desired traits like, taste, fertility, size, disease resistance etc. Genetic enineering and Biotechnology has carved a niche of its own in th field of Science these days and is a promising feild which would address many problems faced by the world today.

Gene structure is the organisation of specialised sequence elements within a gene. Genes contain the information necessary for living cells to survive and reproduce. In most organisms, genes are made of DNA, where the particular DNA sequence determines the function of the gene.

Genes are what is inherited from an organism's parents and what give the offspring certain characteristics of the parents, and alleles are different forms of a gene. For example, there are several different alleles for eye color genes, such as blue alleles (blue eyes) and brown alleles (brown eyes).

Answer: B. The hydrosphere

Explanation:

Hydrosphere means “all the waters on the earth’s surface...” so even the waters in the Everglades would be included. Hope this helps!

The Hydrosphere is the part of the Earth system that includes the water in the Everglades. Thus, the correct option is B.

A Hydrosphere may be characterized as the combination of water and its derivative forms present around the Earth's planet.

The hydrosphere represents all the sources of water available worldwide such as in lakes and streams, subsurface water, the ice of glaciers, and water vapor on the earth's planet.

It is the region of the whole earth that significantly comprises all source of water and its derivatives compounds like water vapor, ice (solid form), etc.

So, the wetland of Florida, i.e. Everglades is also includes the hydrosphere part of the Earth system.

Therefore, the Hydrosphere is the part of the Earth system that includes the water in the Everglades. Thus, the correct option is B.

Answer:

I think it's because it will decay and be soil and soil is biotic factor

A dead tree would still be a biotic factor, even though it is no longer alive because biotic factors include living organisms and the remains of the living organisms.

Biotic factors are those factors that are living and growing and reproducing.  The living organism that were once lived are also comes sunder biotic factors.

A dead tree mean a dried tree that still has wood and dry leave. The wood will decompose or will use in burning purpose. The dead tree will still consider as a biotic factor because it was once alive.

Thus, Even if it is no longer alive, a dead tree would still count as a biotic factor because biotic factors comprise both living species and their remains.

Answer:

1. lactose intolerant

2. lactase

3. dairy products

4. E.coli

5. enzymes

6. proteins

7. repressor

8. operator

9. RNA polymerase

10. transcribe

11. bases

12. repressor

13. operator

14. transcription

Explanation:

Lac operon is good example of prokaryotic gene regulation. The lactose operon or lac operon is a type of operon which is use to transport  and metabolize the lactose in E.coli and other bacteria. The lac operon is made up of three important components including promoter, an operator, and three genes that encode the enzymes required for lactose digestion.

A person who is lactose intolerant is unable to produce the enzyme lactase, which helps in the digestion of sugar generally present in dairy products. The lac operon is regulated by lactose in the environment.

So, when lactose intolerant people consume dairy products, the gens in bacteria E.coli present in the large intestine, turn on to produce enzyme or  proteins required to digest the lactose.

When lactose is present, lac operon in E.coli, acts as an inducer and binds to the repressor protein which prevent it binding to the operator. RNA polymerase the binds to the promoter and transcribe the E.Coli gene by matching the base pair or bases.

When lactose is absent, repressor protein is allow to bind to the operator and inhibit the transcription process in E.Coli. The whole process is regulated during transcription in prokaryotes that involves lac operon.

Hence, the correct words for the blanks are as following:

1. lactose intolerant

2. lactase

3. dairy products

4. E.coli

Answer:

A Food Suply

Explanation:

Malthus believed that the population size would be limited by the availability of food supply. He argued that while populations have the potential to grow at a geometric rate, the food supply could only increase at an arithmetic rate. Hence option A is correct.

There are various ways to limit population size, some of which include:

Birth control: Providing access to contraception and family planning services can help to control birth rates and reduce population growth.

Education: Educating people, especially women, about the benefits of having smaller families can also help to reduce population growth rates.

Economic incentives: Providing economic incentives, such as tax breaks or financial rewards for having smaller families, can also help to limit population growth.

Malthus believed that this was a natural and inevitable process and that efforts to alleviate poverty and suffering would only lead to more population growth and ultimately exacerbate the problem.

This means that the population would eventually outgrow the available food supply, leading to famine, disease, and ultimately population control through natural selection.

Hence option A is correct.

Let's break it down:

-If the study has been conducted by multiple others and they get different results, it might be a sign that something went wrong in the experiment, and the data is unreliable. For example, if everybody else timed an event and got the same exact time except for the fact that you got a different time, you may start to suspect that you had done something wrong and the data was unusable.

Answer:

When an allele is dominant, the characteristic it is connected to will be expressed in an individual. When an allele is recessive, the characteristic it is connected to is less likely to be expressed. Recessive traits only manifest when both alleles are recessive in an individual.

Explanation:

Dominant means that one of the versions trumps the other. In our example here, brown is dominant over blue so you end up with brown eyes.

The way people write out dominant and recessive traits is the dominant one gets a capital letter and the recessive one a lower case letter. So for eye color, brown is B and blue is b.

Answer:

global temperature increasing as CO2 concentration increases

Explanation:

Global warming is the progressive increase in the temperature of the earth's atmosphere. Global warming is caused by an increase in the concentration of greenhouse gases e.g CO2, chlorofluorocarbons etc. These greenhouse gases, in which carbondioxide is an important example, are capable of trapping heat in order to keep the earth warm.

Howeever, as the concentration of CO2 and other greenhouse gases increase in the atmosphere, the earth's atmospheric temperature also increases above normal, causing Global warming.

In this case, the science teacher's graph will show that global temperature is increasing as CO2 concentration increases.

​Shotgun Sequencing

Explanation:

Shotgun sequencing is a laboratory technique for determining the DNA sequence of an organism's genome. The method involves breaking the genome into a collection of small DNA fragments that are sequenced individually. A computer program looks for overlaps in the DNA sequences and uses them to place the individual fragments in their correct order to reconstitute the genome.

Answer:

1. shotgun

2. inbreeding

3. cloning

4. Y chromosomes

5. The Human Genome Project sought to map a human's entire genome.

6. Inbreeding is a type of selective breeding that occurs when individuals with similar characteristics continue to be bred in an attempt to keep a certain set of traits. However, inbred organisms are genetically similar, and the probability that members of the population will receive mutated alleles leading to disorders is high.

7. Since no two humans have the same DNA, except for identical twins, forensics can take advantage of this fact by using DNA fingerprinting to solve crimes, convict wrongdoers, or overturn unjust convictions.
