During sexual reproduction, two gametes merge to create a zygote that is a genetic mix of its two parents. For each statement, i

ndicate whether it is true or false for sexual reproduction. 50% of the genome of the zygote will come from each parent. Answer 1 Sexual reproduction produces greater genetic variability than asexual methods. Answer 2 50% of the chromosomes in the zygote will match the chromosomes found in one parent, and 50% will match those found in the other parent.

Answer:

1. 50% of the genome comes from each parent because it is crucial otherwise if the ratio changes, the zygote may not form and if formed the fetus may have some other kind of chromosome number related syndromes etc.

2.  Sexual reproduction produces greater genetic variability than asexual methods. This is because of the process of crossing over during meiosis that exchange the segments of chromosome that is necessary for producing mutations and genetic variability.

3. 50% of chromosomes match with each parent because both of the parents contributed 23 chromosomes and exactly 50% of their genome.

4. The gametes must be produced by two different individuals cause that is the main purpose of sexual reproduction and give better survival like this to the forming next generation. Not to mention produces greater genetic variability among species.

5. Plants always produces both eggs because they are hermaphroditic in nature.

Answer:

Answer 1: True

Answer 2: True

Answer 3: True

Answer 4: False

Explanation:

  1. 50% of the genome of the zygote will come from each parent is true because  in a zygote, 50% are from father and 50% of genome from mother.
  2. Sexual reproduction produces greater genetic variability than asexual methods is true because of recombination and independent assortment during gamete formation in meiosis will produce genetic variation in gamete. When fusion of such gamete occurs. This produces create genetic diversity in sexual reproduction whereas in asexual reproduction, such recombination are not seen.
  3. 50% of the chromosomes in the zygote will match the chromosomes found in one parent, and 50% will match those found in the other parent is true because 50% of the chromosomes are of maternal in nature where as 50% are paternal in nature in zygote.
  4. The gametes must be produced by two different individuals is False because in case of monoecious plant and animals, make and female gamete are produced by same individual also.

Which molecule is secreted from the peritubular capillary network into the convoluted tubules?
kow [346]
The correct answer is  H+.
<span>Secretion from the peritubular capillary network into the convoluted tubules is a process called tubular secretion. This is an important process for both waste removal and acid-base balance. The secretion step is usually used to remove drugs, toxins, and poisons, or other molecules such as potassium (K+) and hydrogen (H+). The secreted molecules come from the peritubular capillaries and pass through the interstitial fluid before going through the wall of the tubule into the lumen of the tubule.</span>

Answer:

The needle loop is use to transfer fungi to a soft agar and this will cause or create more fungal growth to occur in the slide.

Explanation:

Needle loop is a tool or device use in microbiology to inoculate microorganisms like bacteria and fungi in media to boost their growth. It is use for sampling and transferring specimens or microorganisms into a media for further analysis, examination and serial dilution.

There are three ways that natural selection can chnage a population. list all three of them AND then describe atleast 2 of them.
Gre4nikov [31]

Answer:

Four conditions are needed for natural selection to occur: reproduction, heredity, variation in fitness or organisms, variation in individual characters among members of the population. If they are met, natural selection automatically results.

Explanation:

Evolution, in genetic terms, involves a change in the frequency of alleles in a population over time. What are the sources of genetic variation? Three sources of genetic variation are mutation, genetic recombination during sexual reproduction and lateral gene transfer.

Which is most likely to change with new discoveries and technologies
pishuonlain [190]
<h2>Answer:</h2>

A) classification of organisms

<h2>Explanation:</h2>

With the advancement of technology, many plants and animal were re-classified and reversed. For instance due to the advanced light microscope, which had high resolution and magnification, scientists were able to identify the structure of many organisms on a highly molecular level. Whitaker was a biologist who distinguished that fungi was separate from plants because fungi doesn’t have chlorophyll. Similarly there are so many evidences that resulted in the re-classification of organisms.
