Name three ways that humans benefit from the use of seedless plants

Answers

Answer:

They support life by being the first vegetation to spring up on harsh terrain where soil is scarce. Even when they perish, seedless plants give back to nature. Certain seedless plants like moss and liverworts actually leave behind a layer of fertile soil for other plants when they perish.

Explanation:

Seedless plants have historically played a role in human life through uses as tools, fuel, and medicine. Dried peat moss, Sphagnum, is commonly used as fuel in some parts of Europe and is considered a renewable resource.

Why DNA synthesis is faster than RNA synthesis?is there any advantage of being faster?

Answers

Answer:

Explanation:

I read it's has to do with the amount of nucleic acid that must be synthesized. RNAs are tiny compared to DNA, so there is little selection pressure for speed. Also, multiple RNA polymerases can initiate simultaneously, effectively increasing the synthesis rate

Answer:An obstacle to the triviality of the first issue includes the fact that DNA polymerase replicates DNA at a rate of 10-15 times faster than RNA polymerase transcribes DNA so that these enzymes inevitably collide if they attempt to function concurrently and co-directionally

Explanation:

At any given instant, only a fraction of the genome (total DNA) is being transcribed. Consequently, speed is not necessary.

Why is it necessary to check total aerobic microorganisms in microbiological quality control but not to test total anaerobic microorganisms?

Answers

Answer:

While many microbes are harmless to humans, others can cause serious problems. They can spoil food, introduce toxins, cause disease and lead to a host of other problems. The importance of microbiological testing is to quickly identify these contaminants and treat them before they do irreversible damage.

The precursor of EGP is translated from a transcript that has had one non templated nucleotide added to the open reading frame. This change does not create or eliminate a stop codon. Compared with the protein sGP, which is produced from the unedited transcript, EGP most likely has the same primary:

Answers

Answer:

Explanation:

It was added somewhere in the middle. Since this is a frameshift, everything downwind of the addition will most likely be different.

The question is basically asking, if you change everything from the middle to the end of an amino acid sequence, which end changes and which end would remain the same?

It basically asks, when amino acids are assembled into proteins, are they built from the amino to the acid direction, or the acid to the amino direction?

The answer is that amino acid sequences are always assembled N to C, much like nucleotide sequences are built 5 to 3.

is mucous an enzyme or harmone​

Answers

Answer:

It's an Enzyme.

Explanation:

It is a viscous colloid containing inorganic salts, antimicrobial enzymes (such as lysozymes), immunoglobulins (especially IgA), and glycoproteins such as lactoferrin and mucins, which are produced by goblet cells in the mucous membranes and submucosal glands.

After fertilization occurs, the zygote undergoes cleavage and gets converted into 2,4,8 and subsequently a 16 celled stage known as morala. Thereafter certain changes occur in the morula and a blastocyst is formed. The blastocyst then gets implanted in the wall of the uterus.

Imprinting can be cell-type specific; for example, this region of chromosome 15 is ONLY imprinted in neurons and a few other specific cell types, but it is not imprinted in most cells in the body, such as bone, liver, and heart cells. Which of the following statements are true about a healthy individual without Prader-Willi or Angelman syndrome? ( Choose two answers)
a. Maternal and paternal copies of SNRPN are expressed at the same level in heart cells.
b. The maternal and paternal copies of UBE3A are differentially expressed in bone cells.
c. The maternal copy of SNRPN has DNA methylation at its promoter in liver cells.
d. Expression of the paternal copy of UBE3A is silenced in neurons.

Answers

Answer:

The correct answer is - A and D.

Explanation:

Genetic imprinting is DNA modifications that result in changing the expression but not the sequence. Factors That affect such changes present both within and outside the cell.

It is a result of the silencing of either maternal or paternal alleles in a pair. This occurs random and leads to phenomenon like X-inactivation. The mechanism involves methylation of the DNA to be silenced. paternal copy of UBE3A is silenced in neurons.

A conservation biologist is working to protect elephant seal populations. Elephant have a classic type I survivorship curve with very low levels of juvenile mortality and high survivorship rate. They insist that reducing threats to adults is more important than protective juveniles. Are they correct

Answers

Answer:

Elephants and Classic Type I Survivorship Curve

The conservation biologist is correct.

Explanation:

Classic type 1 survivorship curve means that mortality of elephants increases as they age, and their fecundity (or fertility) decreases as they age.  Therefore, reducing the threats to adults should be more important than protecting the younger elephants.  The younger elephants have higher rates of survival and fecundity than their older parents.
