Before the marble starts rolling, it is potential energy. Once it is rolling, it is kinetic energy. You know it stays the same because the marble probably would not be rolling if it weren't. All that's happening is that the ball is rolling faster because of gravity.

Gravity assists the marble, leading to conservation of energy. The stored energy is release as momentum, the output of energy is constant.

What would be the most likely effect on the transcription of the trp structural genes for the mutation scenarios provided? mutat

blagie [28]

Answer:

I've responded to each scenario individually, please see below:

1. mutation that prevents ribosome binding to the mRNA

No transcription occurs

2. 5' UTR mutation that changes region 1 tryptophan codons into alanine codons

Transcription when alanine is low

3. mutation that creates a stop codon in region 1 of mRNA 5' UTR

Transcription occurs, a truncated protein will be made during translation

4. deletions in region 2 of the mRNA 5' UTR

Transcription occurs, region 1 and 2 might get paired together

5. deletions in region 3 of the mRNA 5' UTR

Transcription occurs, region 3 and 4 could combine to form a hairpin loop structure

6. deletions in region 4 of the mRNA 5' UTR

Transcription occurs, region 3 and 4 could combine to form a hairpin loop structure

7. deletion of the string of adenine after region 4 of the mRNA 5' UTR

Transcription occurs, however, it will not be as stable a molecule because of losing its polyA tail

Hope that answers the question, have a great day!

According to the image below, which season is about to begin in the northern hemisphere?

vova2212 [387]

Answer:

winter

Explanation:

On this image, we can see the Earth being tilted away by 23.5 degrees from the Sun. This tilting puts the Northern Hemisphere in a situation where it is the one that is tilted away from the Sun, thus it will receive less sunlight, as well as less direct sunlight. That will cause lower temperatures on the Northern Hemisphere, thus the winter season will start, and it will last for around three months, at least at the mid-latitude zones. On the other side, the Southern Hemisphere is more exposed to the Sun during this tilting, so t receives more sunlight, and more direct sunlight, resulting in summer in this half of the planet.

One a feature of the structure of all DNA Molecules is the

liberstina [14]

Answer:

The structure of the DNA is ideal for the complex function that it plays.

Some of the features of the structure of all DNA molecules are:

Sugar- phosphate backbone:

The sugar- phosphate backbone is ideal for providing the DNA a ladder- like shape which is essential for its functions.

Hydrogen bonds:

The hydrogen bonds present in the nucleotides keep both the DNA strands intact. If the hydrogen bonds were not present then the double helix would not have been able to form.

Coiling:

The structure of the DNA is coiled and super coiled so that it can fit into an organism.

What are organelles and which type of cell has organelles? *

xxTIMURxx [149]

Answer:

An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
