Answer 1

Answer: 1 hope it helps

Explanation:

Answer 2

Mutation 1 will cause translation to stop as there is presence of stop codon UAG, UAA, UGA.

What are the stop codons ?

In DNA or messenger RNA (mRNA), a stop codon is a sequence of three nucleotides (a trinucleotide) that tells the cell to stop making proteins. There are 64 distinct codons for trinucleotides. Three stop codons (UAA, UAG, and UGA) and 61 specific amino acids are included.Several codons, or triplet bases, make up the universal genetic code. To reduce coding errors, the standard code has developed over time. The genetic code is made up of 64 codons that are the result of the four bases in nucleic acids being permuted and combined.Since more than one codon can encode for a single amino acid, the genetic code is degenerate. Consequently, 61 of the 64 codons encode the 20 amino acids.The START and STOP codons, two punctuation marks in the genetic code, indicate the conclusion of protein synthesis in all organisms.Because it is the first codon in the transcribed mRNA to undergo translation, the codon AUG is referred to as the START codon. The amino acid methionine (Met) in eukaryotes and formyl methionine (f Met) in prokaryotes are both encoded by the most prevalent START codon, AUG. With the assistance of a few initiation factors, the t RNA recognizes the START codon AUG during protein synthesis and initiates mRNA translation.Amber (UAG), opal or umber (UGA), and ochre (UAA) are the three STOP codons. Charles Steinberg and Richard Epstein discovered Amber" or UAG and gave it the name "amber" after the German meaning of their friend Harris Bernstein's last name. In order to keep with the theme of "color names," the two remaining STOP codons were subsequently given the names "ochre" and "opal."

if a sample contains 20g of an isotope that has a half life of 1000 years how much will be left after 2000 years

Answers

5 grams will be left. After the first 1000 years, there will be half of 20 left, or 10. After 2000 years, half of 10 will remain, which is 5.

After 2000 years, there will be 5g of the isotope remaining.

What is an isotope?

If an isotope has a half-life of 1000 years, it means that after 1000 years, half of the original sample will have decayed. After another 1000 years (2000 years total), half of the remaining sample will have decayed, and so on.

To calculate how much of the sample will be left after 2000 years, we can use the following formula:

[tex]N = N_{0} * (1/2)^ (t/T)[/tex]

where:

N = the amount of the isotope remaining after time t

N0 = the initial amount of the isotope

t = the time that has elapsed

T = the half-life of the isotope

Plugging in the values from the problem, we get:

N = 20g * (1/2)^(2000/1000)

N = 20g * (1/2)^2

N = 20g * 1/4

N = 5g

Therefore, after 2000 years, there will be 5g of the isotope remaining.

The mechanoreceptors sensing light touch are concentrated on

A. the back of the body.
B. hairy skin like forearms and legs.
C. hairless skin like lips and fingertips.
D. the scalp.

Answers

Answer:

Hairless skin areas

Explanation:

The mechanoreceptors sensing light touch are concentrated on Hairless skin like lips and fingertips, option C is correct.

Mechanoreceptors sensing light touch are most concentrated on hairless skin regions such as lips and fingertips. These areas have a higher density of specialized touch receptors, known as Meissner's corpuscles and Merkel cells, which are particularly sensitive to light touch sensations. Hairless skin allows for more direct contact with external stimuli, enhancing the perception of gentle touch and fine tactile discrimination.

In contrast, areas with hair, like the back of the body or the scalp, have a lower density of these mechanoreceptors and are more involved in detecting other sensory modalities such as temperature or pain, option C is correct.

Choose the best explanation of a partial solar eclipse?
A. The earth only partially covers the sun during the eclipse
B. The moons phase is full and blocks out most but not all of the sun
C. During a new moon phase there is usually a partial but not total eclipse
D. The moon only partially covers the sun during the eclipse

Answers

Answer:

The best explanation for a partial solar eclipse is that moon only partially covers the sun during the eclipse (option D).

Explanation:

A solar eclipse occurs when the moon stands between the sun and the earth, which happens when the moon is near the plane of the ecliptic, that is, the point where the orbits of the earth and the sun intersect.

A partial solar eclipse occurs when the moon partially covers the sun, which depends on the observer's point of view on the earth and his geographical location.

The other options are not correct because:

    A. If the earth stands between the sun and the moon, lunar eclipses occur.

    B and C. During a solar eclipse it is not possible to see lunar phases, which occur when the sun's rays are reflected off the satellite.

1.what are three factors that affect the rate of chemical reactions?

2.select one of these factors and describe how it affects chemical reactions within our bodies.

Answers

Explanation:

The factors that affects the rate of chemical reactions are;

Nature of reactants Concentration of reactants or pressureTemperature Presence of catalystSunlight

In our body, the nature of reactants is very important. A food substance in solid form undergoes slow digestive process because it has little surface area exposure for the action of digestive chemicals. Most solid food are usually chewed in the mouth before digesting them to increase their surface area.

The increasing order of food digestion is;

   lumps to granules to powder and to liquids.

The plasma membrane is selectively permeable. It allows some substances to enter and leave the cell unrestricted while others are restricted. Some toxins produced by certain bacteria cross the plasma membrane, interfering with normal chemical reactions, and ultimately killing the affected cell. Why are cells unable to stop the flood of these harmful substances into the cell

Answers

Answer:

There are specific receptors present on the surface of the normal cell membrane to recognize the molecules to allow them to pass or not. Most of the bacterial toxin are water-soluble molecules, and bound to the cell surface and interact with them as some time antibody-antigen interaction or cell recognition does not occur that form a pore in the cell membrane and toxins move into the cell.

Once toxins enter the cell they attack intracellular targets through endocytic vesicles. Ultimately these ends in cell death.

The cells are not able to stop the flow of the mentioned harmful substances into the cell as they fail to recognize them as foreign entities. These foreign toxins have intracellular targets with which they bind and lead to death of the cell.

Cell death due to foreign toxins:

The plasma membrane is formed of lipids. The toxins produced by the bacterial cells are water soluble. Therefore, they identify particular receptors on the membrane and associate with them. Thus, cell at certain occasions fail to identify them as foreign entities.

They combine with the plasma membrane of the cell and induce pore formation, however, there are many toxins that invade the cell and possess intracellular targets via endocytic vesicles. With the help of these vesicles, they deliver their enzymatic domain into the cytosol and results in the death of the cell by obstructing the metabolism of the cell.

Thus, cells fail to identify the bacterial toxins as foreign entities and they invade the cell and results in cell death.

If a woman is heterozygous for widow's peak
(widow's peak is dominant over a smooth hairline) has children with a man with a smooth hairline, what
are the possible phenotypes of their children?
It is impossible to determine the possible phenotypes.
O All of their children will have a widow's peak.
O None of their children will have a widow's peak.
It is possible for their children to either have widow's peak or a smooth hairline.

Answers

Answer:

It is possible for their children to either have widow's peak or a smooth hairline.

Explanation:

Let's say that the widow's peak allele is W (dominant) and the smooth hairline is w (recessive).

A woman heterozygous for widow's peak is Ww. A man with a smooth hairline must have two copies of the smooth allele since it is a recessive trait, so he must be ww.

The cross is Ww x ww

                    W               w

    w            Ww            ww

    w           Ww           ww

There is a 50% chance that the children will have the genotype Ww, and therefore have a widow's peak. There is a 50% chance the children will be ww, and will therefore have a smooth hairline.

So, It is possible for their children to either have widow's peak or a smooth hairline.
