What would be the consequence of absence of tRNA in the cytoplasm?

Vladimir [108]

The consequence of the absence of tRNA in the cytoplasm is that the correct amino acids won't be transferred to the ribosome, and protein synthesis would fail. The correct answer is going to be B.

Is Solid waste point source pollution or non point source pollution?

Yanka [14]

Answer:

Nonpoint-source pollution is the opposite of point-source pollution, with pollutants released in a wide area. As an example, picture a city street during a thunderstorm. As rainwater flows over asphalt, it washes away drops of oil that leaked from car engines, particles of tire rubber, dog waste, and trash. The runoff goes into a storm sewer and ends up in a nearby river. Runoff is a major cause of nonpoint-source pollution. It is a big problem in cities because of all the hard surfaces, including streets and roofs. The amount of pollutants washed from a single city block might be small, but when you add up the miles and miles of pavement in a big city you get a big problem.

In rural areas, runoff can wash sediment from the roads in a logged-over forest tract. It can also carry acid from abandoned mines and flush pesticides and fertilizer from farm fields. All of this pollution is likely to wind up in streams, rivers, and lakes.

Airborne pollutants are major contributors to acid rain. It forms in the atmosphere when sulfur dioxide and nitrogen oxides combine with water. Because acid rain results from the long-range movement of those pollutants from many factories and power plants, it is considered nonpoint-source pollution.

Dr. Susa flashed a picture of a cat in the right visual field of a split-brain patient. The patient could most likely: (3 points

lyudmila [28]

Answer:

The answer is:

verbally report that a cat was seen

write the word cat using their left hand

Explanation:

"Split-brain" is<em> a condition of having "two brains" in one body.</em> This is also known as "callosal syndrome." This happens when a person experiences seizure and in order to control it, the "corpus callosum" (divides the lobes into left and right hemispheres) is being severed. Once it is severed, the hemispheres will function as a <em>separated brain.</em> This treatment is only done as a last resort.

The person who has a split-brain will have two separate perceptions and impulses of things.

In the situation above, the patient is shown a picture of a cat in the right visual field. This means that the image of the cat will be sent to his left hemisphere. Left hemisphere is more active when it comes to the production of speech, thus the patient will be able to verbally report that a cat was seen. (thus, this explains the answer).

Since the left hemisphere is also responsible for "writing," then he can also write the word "cat" using his left hand. (thus, this explains the answer)

In translation, the cell uses the genetic information contained in mRNA to make the proteins that carry out the cell's work.

Jobisdone [24]

Answer: d). UAG

Explanation: During translation, DNA sequence is first of all copied into an mRNA in a process known as transcription. This is the first step in protein synthesis. The mRNA is used as a template in protein synthesis. The genetic information encoded in an mRNA are in form of codons. A Codon is a three nucleotide sequence that codes for a specific amino acid. These codons are recognized by anticodons in a tRNA molecule. An anticodon is a three-base sequence on the tRNA through which tRNA base pair with mRNA.

From the DNA sequence above, 3'TAG will first be transcribed into an mRNA sequence AUC, then the anticodon on the tRNA will be UAG. The mRNA codon-tRNA anticodon base pairing follows the Watson and Crick base pairing in which Adenine pairs with Uracil and Cytosine pairs with Guanine.

True-breeding flies with singed bristles (s) and normal wings (L) were crossed to true-breeding flies with normal bristles (S) a

mina [271]

Answer:

The correct answer is -

Possible F2 offspring genotypes and phenotypes:

SsLl: normal bristle, normal wing

Ssll: normal bristle, vestigial wing

ssLl: singed bristle, normal wing

ssll: singed bristle, vestigial wing

Explanation:

In this case, the genes 's' and 'L' and genes 'S' and 'l' are linked, they will be passed on to the gamete together.

The cross would be as follows:

F1:

Parents: singed bristles and normal wings x normal bristles and vestigial wings

Genotype: ssLL SSll

Gametes: sL Sl

F1: SsLl ( normal bristles and normal wings )

For F2,

Parents: normal bristles and normal wings x singed bristles and vestigial wings

Genotypes: SsLl ssll

Gametes: SL, Sl, sL, sl

Cross:

SL Sl sL sl

sl SsLl Ssll ssLl ssll

Thus the possible offspring will have -

SsLl: normal bristle, normal wing

Ssll: normal bristle, vestigial wing

ssLl: singed bristle, normal wing

ssll: singed bristle, vestigial wing
