which is true regarding the process of meiosis I?
A) chromosome Number is reduced from diploid to haploid
B) sister chromatids in a cell undergoing are always identical
C) Most homologue pairs do not have any crossovers during prophase I
D) sister chromatids separate to opposite ends of the cell

Answers

Answer: The correct option is A (chromosome Number is reduced from diploid to haploid)

Explanation:

In sexual reproduction, offspring are produced by fusion of two different sex cells which usually come from two different parents. These sex cells are know as gametes.

Meiosis is a type of cell division that gives rise to gametes in which the chromosome number is halved. Thus, the gamete cell is said to contain a haploid number (n) of chromosomes.

A diploid cell has two sets of chromosomes: one from the male parent and the other from the female parent. When a diploid cell undergoes meiosis the following occurs:

--> the chromosomes replicate once and

--> the nucleus and cell duplicate ( divide equally) twice.

As a result, the diploid parent cell gives rise to four haploid gamete cells. Therefore the statement "chromosome Number is reduced from diploid to haploid ' is true concerning meiosis I.

How are the sensory receptors for hearing and touch similar?

Answers

Answer: salah it is good for ur breath.

Explanation:

The sensory receptors for hearing and touching are similar because the sensory receptors take the message from that sensory area, and most of the stimulus is vibration.

What are sensory receptors?

The receptor is present on the cell surface, and the sensory receptor is present on sensory areas such as the skin, ear, and so on, and most of the time the stimulus is carried out by the sensory neuron to the brain or spinal cord. The sensory receptor takes the stimulus, and later, in the spinal cord or in the brain, it is further programmed and the action is generated. The action is generated by the sensory stimulus, and then, with the help of the motor neuron, the action is seen.

Hence, the sensory receptors for hearing and touching are similar because the sensory receptors take the message from that area, and most of the stimulus is vibration.

The red line represents the actual bear population, while the blue line shows the predicted population. Why doesn't the actual bear population ever match the exact carrying capacity?

Answers

Answer:

Explanation:

Predicted populations are ideal circumstances and do not account for many of the external factors that can affect the data in the current study. Therefore, many times the actual population is either lower than the population or exceeds it but is almost never exact. This can be due to weather conditions that cause a large portion of the population to die out, excess food, hunters, etc. Many factors can drastically affect whether the population is dying or thriving.

Answer:

Glucagon is released to stop blood sugar levels dropping too low (hypoglycaemia), while insulin is released to stop blood sugar levels rising too high (hyperglycaemia). The release of glucagon is stimulated by low blood glucose, protein-rich meals and adrenaline (another important hormone for combating low glucose).

Explanation:

It is given that slimy snort S is dominant over stringy snort s which means in case, of heterozygous the slimy snort will be expressed only.

The cross between Ss and Ss will produce gametes S, sand S, s.

then,

     S    s

S   SS  Ss

s   Ss   ss

From the given punnett, it is clear that there are 1 stringy snort offspring and three slimy snort offspring will be produced which means, there is 25% likelihood of stringy snort and 75% likelihood of slimy snort.

Genotypically there are 1 dominant: 2 heterozygous : 1 recessive present.

Look at Scenario A below and select the correct Punnett Square that corresponds with the scenario. For all questions, the trait being studied is seed color - red seeds (R, dominant) and pink seeds (r, recessive). Scenario A: Parent 1: heterozygous Parent 2: pink

Answers

Answer: A

Explanation:

Heterozygous means it has both a recessive and a dominate allele so in this case it’d be shown as Rr. For a parent to appear pink, the genotype must be rr (because r is recessive and won’t show up in the parent if there’s a dominant allele to over lower it). The only option that shows an Rr and rr pairing is option A

only about ten per cent of the biomass is transferred from each trophic level to the next. The remaining 90 per cent is used by the trophic level to complete life processes . Biomass can be lost between stages because not all of the matter eaten by an organism is digested.

Movement of the particles across the membrane stops when the concentration gradient no longer exists, the particles will continue to diffuse due to random motion

Answers

Answer:

Once the concentration gradient no longer exists, particles will continue to diffuse due to random motion.

Explanation:

When there is a permeable membrane between two solutions with different concentrations, the concentration gradient will go from the compartment with more particles to the one with fewer particles to valance the concentrations on both sides of the membrane. Once the concentrations are equal, particles will still randomly move from one side to the other, but the number of particles that move to one side is almost the same as the number of particles that move to the other, so there is still valance and the same concentration in both sides.

help me because I mean you should cuz it's a nice thing to do ​

Answers

Answer:

the answer is C

Explanation:

Mutations are genetic changes in the DNA sequence of the genome in a particular organism. Mutations are caused by adding one or more extra nucleotides into the DNA (i.e. insertions), deleting nucleotides (i.e. deletions), or replacing nucleotides (i.e., substitutions). Due to the diverse nature of mutations, it is expected that they have different effects on the gene product (i.e., the resulting protein). For example, a deletion or an insertion, which are collectively are referred to as 'indels' mutations, may generate frameshift mutations that shift the way the DNA sequence is read. Moreover, if a nucleotide letter is written backward, it doesn't change the final product (i.e., the nucleotide sequence), which is represented in the example with the C option.

If 30% of a DNA sample is composed of thymine nucleotides, what percentage of the DNA sample would be composed of cytosine nucleotides?

Answers

Answer:

20%

Explanation:

Pairing do occur between a purine and a pyrimidine base or a pyrimidine and a purine base where Adenine pairs with Thymine and Guanine pairs with Cytosine.

DNA(deoxyribonucliec acid) sample is usually compose of 100% nucleotide base,

Since 30% of the sample section is compose of thymine then Adenine the base pair will also be 30% this is because adenine will always pair with thymine and each will occur in equal quantity. Together, adenine and thymine compose 60% of the segment.

While the remaining 40% of the section is composed of guanine and cytosine pairs and since the two bases will be equal in quantity, 20% of the DNA section will be cytosine nucleotide.
