Answer:

reverse transcriptase (RT) is an enzymeused to generate complementary DNA (cDNA) from an RNA template, a process termed reverse transcription. Reverse transcriptases are used by retroviruses to replicate their genomes, by retrotransposon mobile genetic elements to proliferate within the host genome, by eukaryotic cells to extend the telomeres at the ends of their linear chromosomes, and by some non-retroviruses such as the hepatitis B virus, a member of the Hepadnaviridae.

Bacteria that live around deep-sea, hot-water vents obtain energy by oxidizing inorganic hydrogen sulfide belched out by the ven

Agata [3.3K]

The correct answer is: chemoautotrophs

Since these bacteria obtain energy by the oxidation of electron donors (inorganic hydrogen sulfide) in their environments (chemical reactions) we can classify them as chemotrophs. In addition, they synthesize all necessary organic compounds from CO2 so they are autotrophs (opposite from heterotrophs that are unable to fix carbon).

Emma’s neighbor had a child with DiGeorge Syndrome, a birth defect in which children are born without a thymus gland. Emma had n

Irina18 [472]

Answer:

The thymus gland can be described as a gland that functions both for the endocrine system and for the immune system.

In the immune system, thymus gland plays a vital role in the development of the T-cells. If thymus gland wouldn't be there, then there will be a reduction in the T- cells of the body. Hence, the immunity of the body will be suppressed.

The thymus, till the time it is active, also protects the body from autoimmunity. If thymus is absent, then there will be suppressed autoimmunity in the child.

Explanation:

micro organisms , though a large number can cause diseases in plants and animals , including humans . But all microbes arent harmful. a number of microbes are very useful, particularly in industries , agriculture and medicine. In fact, their beneficial effects are far more than the harm they cause.May 20, 2016

30 POINTS HELP ASAP! WRITE IN YOUR OWN WORDS!!! I WILL MARK BRAINLIEST HELP PLEASE ITS DUE TODAY AND I REALLY NEED TO GET IT DON

Elis [28]

Answer:

Stem cells are cells in the human body that have the ability to develop into many other body cell types. Stem cells are very useful for drug development, research, they aren't likely to be rejected in transplants, and are used to repair damaged or diseased cells and tissues. However, they cannot be grown for long periods of time, there are very small numbers in each tissue and cell making them very hard to find, and for certain studies they have been shown to cause cancer. To be honest, using them in research does have its pros and cons, they are very useful and easier to use in research, plus they can help repair damaged and diseased cell tissues. But at the same time they can be difficult to use correctly and properly, it can cause serious health problems if cancer doesn't take place. I think that using them in research is okay, as long as they are used correctly and properly.

Hope this helps! :)

For this week's CRQ, you are to design your own genetic cross between a female and a male. Be sure to include each of the follow

svp [43]

Answer and Explanation:

Punnett squares are illustrations that display the product of hybrid trait crosses by genetic breeding. Established parent genotypes and phenotypes are used and are usually compatible with Mendelian ratios and inheritance. The phnomenon influencing this behaviour is the

Law of Segregation,
Law of Independent assortment
and Dominance

For this cross...

Assuming Widow's peak= dominant

1. What are the dominant and recessive traits in cross?

Parent generation or P generation:

gametes: Ww → Widow's peak dominant (W), No Widow's peak recessive (w)

2. Is the male homozygous dominant, homozygous recessive, or heterozygous?

Heterozygousity describes the allelic makeup; these traits are made of two different forms of the same gene.

Male: Ww → with the W.peak;

(Thus, with both W and w this is a heterozygous trait)

3. Is the female homozygous dominant, homozygous recessive, or heterozygous?

However, homozygous traits are made up of the same forms of the gene called alleles.

Female: ww → without the W.peak

(Thus, with both w ad w this is a homozygous trait)

1. genotypes and phenotypes for parent and offspring...

Assuming heterozygousity of the male , for the cross

P generation: Ww× ww

Widow's peak ×No Widow's peak

F1 generation:

genotype: Ww × ww ...(from punnet square)
phenotype: 2 with the W.peak; 2 without

∴ 50% are genotypically heterozygous while 50% is homozygous , 2 with the W.peak; 2 without
