Which of the following best predicts and justifies how the proportion of the Tibetan population with big blood vessels living in the mountains will change over the next 1,000 years (assuming conditions remain stable)?

Question 2 options:

I predict that the proportion of individuals with big blood vessels living in the mountains will decrease because there is a variation in blood vessel size and those with the smaller blood vessels can store more red blood cells than larger vessels, so more oxygen can be moved to the body cells. Therefore, they have a better chance of surviving and passing this trait on to their offspring.


I predict that the proportion of individuals with big blood vessels living in the mountains will stay the same because there is a variation in blood vessel size and that variation will remain in a population. The is what is so cool about humans, we are all so unique.


I predict that the proportion of individuals with big blood vessels living in the mountains will increase because there is a variation in blood vessel size and those with the bigger blood vessels can deliver more oxygen to the body cells and therefore have a better chance of surviving and passing this trait on to their offspring.


I predict that over 1,000 years, the proportion of individuals with big blood vessels living in the mountains will not change because a change can’t happen to an individual, an individual can only increase the amount of red blood cells it makes, not its blood vessels.

A layer of resin and woody tissue sticks the cones' scales together. The seeds are locked in tight, and the cones can't open unless they're exposed to VERY high temperatures like the type of temperatures that fire provides. This shows they survive through exposing the seeds after forest fires.

Answer:

Pale leaf spots eventually develop into spore-producing structures called pustules.

The pustules are found most commonly on the lower leaf surface and produce huge numbers of microscopic spores.

Pustules can be orange, yellow, brown, black or white.

Explanation:

Answer:

Please find the mRNA and amino acid of the DNA sequence in the table below.

Explanation:

This question is describing the processes of transcription and translation. Transcription is the synthesis of mRNA from a DNA template while translation is the synthesis of an amino acid sequence from a mRNA sequence.

The following nucleotides combination are given in this question. Their transcription into mRNA using the complementary base pairing rule is as follows;

DNA = mRNA

- ATG = UAC

- GTA = CAU

- CAA = GUU

- AAT = UUA

- GCG = CGC

- TGT = ACA

- ACT = UGA

- CCC = GGG

- TAG = AUC

Using the codon chart attached as an image, the translation of these mRNA codons is as follows:

mRNA = amino acid

- UAC = tyrosine (tyr)

- CAU = histidine (his)

- GUU = Valine (Val)

- UUA = Leucine (leu)

- CGC = Arginine (Arg)

- ACA = threonine (Thr)

- UGA = STOP codon

- GGG = Valine (Val)

- AUC = Isoleucine (Iso)

Answer:

test two:

some short fur and some long fur will be seen.

this is because in some cases, the offsprings have only have the trait for short fur or just one trait for long fur and so short fur is expressed in the phenotype. in other cases, the offsprings have only the trait for long fur and so long fur is expressed phenotypically.

test three:

all long fur is seen.

since all the offsprings only have the trait for long fur and no trait for short fur, long fur is expressed in the phenotype.

Assuming a diallelic gene coding for the trait and expressing complete dominance, 1) all short fur. 2)some short and some long fur. 3) all long fur.

According to the information that was provided, we can assume that the trait fur length is coded by a single diallelic gene

• dominant allele F codes for short fur

• recessive allele f codes for long fur

We can also assume that the gene expresses complete dominance.

It is the inheritance pattern in which the dominant allele completely masks the recessive allele.

This is the case of individuals that are heter0zyg0us for a particular gene and express the dominant phenotype. The dominant allele is hiding the expression of the recessive allele.

Many genes show complete dominance.

Answer: make

Explanation:

Answer:

The correct answer is -

1 - The stimulus is received by sensory receptors.

2 -  Sensory neurons carry stimulus information to the brain or spinal cord.

3 -  The brain processes the information through interneurons.

4 -  Interneurons transfer response information to motor neurons.

5 - Motor neurons cause muscles to contract so the body can react to the stimulus.

Explanation:

In most of the organism including humans body response according to the stimulus it receives. The stimulus is received by the sensory receptors to the sensory neurons or afferent neurons that are present on the skin, nose tongue ears, or eyes. Many other receptors and pain receptors present on various internal organs as well.

These sensory neurons carry the stimulus to the spinal cord or brain where this information received by the stimulus process through interneurons and transfer the response of the particular stimulus to the motor neurons. These motor neurons result in muscles contracts so the body can react.

Answer:

fibras nerviosas

Explanation:

Los nervios están compuestos por grupos de fibras nerviosas las cuales consisten de axones y las vainas que los recubren. Una fibra nerviosa está generalmente compuesta por 1-un cilindroeje (axón), es decir, una prolongación alargada de la neurona la cual conduce el impulso nervioso (señal eléctrica), 2-el axolema, o membrana celular del axón, 3-la vaina de mielina que rodea el axón y 4-el neurilema que rodea la fibra. Las fibras nerviosas se clasifican en 1-fibras mielínicas, cubiertas por la vaina de mielina, y 2-fibras amielínicas, no recubiertas por esta vaina. La presencia de la vaina y el diámetro de la fibra influyen en la velocidad de transmisión del impulso eléctrico a través de la fibra nerviosa.

Answer: photosynthesis

Explanation:

Answer:

Primary succession is the colonization of species of organisms on life-less barren lands after a volcanic eruption, newly formed land, or sand dunes. Lichens and mosses are the known primary succession community of organisms that helps in developing conditions for secondary succession by breaking rocks and providing soil.

After a fair amount of time, there are new species of organisms that grow and colonize in the land and these are, and ultimately the community becomes fairly stable. A climax community is a more stable, mature community that undergoes little or no change which can live for hundreds of years on the land.

The long-term survival of species is dependent on various kind of resources that may be limited, this can be explained by the lichens and mosses that have enough amount of nutrition and resources during primary succession but as new organism comes with complex structure and competes with these lichens and mosses their number decline due to limited amount of resources.

The different forms of the beef cattle color gene are called "alleles"

Alleles are alternative versions of a gene that arise from mutations and are located at the same position on a chromosome.

In the case of beef cattle, the color of the animal is determined by the interaction of multiple genes, including the color gene. The color gene can have different alleles that influence the color of the animal's coat. For example, one allele may result in a black coat color, while another allele may result in a red coat color.

The combination of alleles that an animal inherits from its parents determines its genotype, which in turn determines its phenotype or observed traits. Therefore, the different alleles of the beef cattle color gene can result in different coat colors, patterns, and markings in the cattle population.

Answer:

B

Explanation:

mRNA is the messenger RNA that exits the nucleus and moves over to the ribosome, but it doesn't go in, tRNA goes in, figure G is tRNA.

Structure B given in the diagram is mRNA which is released out of the nucleus to undergo translation for the synthesis of proteins. So option B is correct.

The mRNA carries the genetic information of an individual from the nucleus of the cell to the cytoplasm. The information encoded in the DNA is first transcribed into mRNA and the mRNA is then transported into the cytoplasm for translation.

The process of translation is aided by the protein factories of the cell which are the ribosomes. The ribosomes bind onto the mRNA and start the process of synthesis with the help of the initiator tRNA and further elongate the chain of amino acids to synthesize a complete polypeptide. There are two different types of ribosomes present in the prokaryotic and eukaryotic cells to carry out translation.
