Name the things which help in the preparation of carbohydrates in plants

Salsk061 [2.6K]

Answer:

People breathe oxygen in and carbon dioxide out, but for a plant to make carbohydrates, the leaves take in carbon dioxide through the stomata on the leaf surfaces. From the stomata, the mesophyll cells use the carbon dioxide to combine it with water and light for photosynthesis.

Inessa05 [86]

Answer:

A scientist's response to the increase in food poisoning sick patients should be examining the type and source within the foods consumed.

Explanation:

Food poisoning involves the effects that decomposed or contaminated food can have on a group of people who eat it, and can cause illness in all or most individuals.

Although patients' symptoms should be treated and preventive education provided, the best course of action for a scientist is to investigate the cause.

The response of a scientist to the increase in food poisoning cases is to determine the type and source of food, as well as the nature of the alteration it has -decomposition, contamination, bacteria- in order to eliminate the source and avoid new cases.

The other options may be valid in the face of the appearance of food poisoning cases, but they are not the best procedure with which a scientist would respond.

Alu element at the PV92 locus on Chromosome 16. In this population, 436 people have a heterozygous genotype and 102 people have

Lesechka [4]

Answer:

Explanation:

According to the exercise we can infer that for the Alu insert:

p: positive allelic frequency

q: negative allelic frequency

maintaining that the population is in equilibrium we can carry out the following formula

p + q = 1 and pp + 2pq + qq = 1

looking for the genotype frequency we clear and obtain the following data

genotype frequency of 2pq = 436/1000 = 0.436

The genotype frequency of qq = 102/1000 = 0.102

This is how we look now:

number of positive people for Alu = 1000- (436 + 102) = 1000- 538 = 46

In this way it is resolved that:

genotypic frequency of pp = 462/1000 = 0.462

p = 0.462 + (0.436 / 2) = 0.462 + 0.218 = 0.680

q = 0.102+ (0.436 / 2) = 0.102 + 0.218 = 0.320

According to the exercise carried out it is deduced:

The value of p in the population is = 0.68

We conclude that our prognosis showing a homozygous positive genotype is: 0.462

____ is the perceptual organization of a complex acoustic signal into separate auditory events. harmonic sound perception acoust

Leto [7]

The correct answer is the source of segregation.

Source of segregation of a complex acoustic signal into separate auditory events. Some sounds which come from different sources, they can be localized by the human brain to where the sound is coming from.
Based on loud of the sound it will be easy for a person to detect where the sound is coming from.

When a germ cell undergoes meiosis, which event would MOST likely result in four aneuploid daughter

sveta [45]

Answer:

B. misalignment of the chromosomes during anaphase I

Explanation:

Aneuploidy refers to an error in the chromosomal number of a cell. This occurs when the chromosomes fail to separate equally into individual cells, a process called MEIOTIC NONDISJUNCTION. Meiotic disjunction can occur in either the anaphase stage of meiosis I or meiosis II, however, different outcomes are produced.

When chromosomes fail to separate at meiosis I, it results in two gametes that lack that particular chromosome (n-1) and two gametes with two copies of the chromosome (n+1). This means that the four daughter cells will have an incorrect number of chromosomes, hence, the misalignment of the chromosomes during anaphase I will result in four aneuploid daughter cells.
