If you are operating your powerboat near a shoreline, what's important for you to do if you want to help prevent erosion is maintain wake speed to avoid swerving in a counter-clockwise direction. This means that you will run the boat at the slowest possible speed if you want to avoid erosion of soil on the shoreline.

Answer:

To protect the shoreline from erosion, and preserve aquatic vegetation, you should reduce throttle to "no wake" speed when close to a shoreline or in small rivers to help prevent erosion. Moreover, you should not operate in shallow water where your prop or pump intake can stir up bottom sediments and destroy aquatic plants. Last but not least, you should drain the bilge and clean the prop before leaving a waterway; if you do not do so, you may transport plants or animals from one waterway to another and disrupt the natural balance of the environment.

Unlike green algae which can only live in water, a waxy covering over the epithelial cells of plants, called the ________ help(s

Pavel [41]

Answer:

Cuticle

Explanation:

Plant cuticle is a waxy covering over the aerial epidermal cells of all the plants. Waxes are composed of cutin and a various organic solvent-soluble lipids. The cuticle is an extracellular hydrophobic layer which provides protection against desiccation and external environmental stresses. In other words the cucticle helps to retain water and give plants an adavanthe to live terrestrial life.

Use the following template strand of DNA and the coding table to determine the correct amino sequence and write this sequence be

REY [17]

DNA and RNA have the main difference in the presence of deoxyribose sugar in DNA and ribose sugar in RNA. One more is the presence of thymine in DNA while the presence of uracil in RNA.

<h3>What is the codon?</h3>

Codon is actually a three-letter code which is a sequence of three consecutive nucleotides in a DNA or RNA molecule which generally codes for a specific amino acid.

The DNA sequence given here is:

T A T A T C T A C G G T C C G G C A T C G A T T T C G

So the RNA sequence for this will be:

A U A U A G A U G C C A G G C C G U A G C U A A A G C.

So according to the table, the amino-acid sequence will be:

Isoleucine STOP Methionine Proline Glycine Arginine Serine STOP Serine.

Generally stop codon is responsible for the termination of protein synthesis.

Thus, this was the amino acid sequence for mRNA according to the given DNA sequence.

which of the following is not an abiotic factor in the prairie ecosystem a water b sunlight c grass d soil

Lapatulllka [165]

Answer:

Grass

Explanation:

Biotic means living. There are some obvious abiotic factors here. The only gray area is what "soil" encompasses

grass-Biotic means living, all of the other choices are not living, and would therefore be abiotic factors

This is because it is a living thing (performs photosynthesis and cellular respiration).

Biotic means living, all of the other choices are not living, and would therefore be abiotic factors

Use the information below to answer the following question(s). In a survey, the rate of heavy smokers was reported as 270 per 10

Eddi Din [679]

The probability that neither of them is a heavy smoker is 0.53 or 53%

<h3>What is genetic probability?</h3>

Probability serves to mathematically estimate the possibility of events that happen by chance, that is, as a matter of luck.

In this case:

Probability that selected one is heavy smoker is:

p=270/1000=0.27

Number of individuals selected is 2 and We know that:

P(X=x)=nc_x(1-p)^{n-x}(p)^x

We need to prove that X=0:

P(X=0)=nc_0(1-0.27)^{2-0}(0.27)^0

P=0.5329
