Who challenged the idea that insects appeared spontaneously in decomposing meat?

ladessa [460]

Francesco Redi was the first scientist to disprove and challenge the spontaneous generation theory. He experimented on how flies distributed their eggs on the meat which caused flies to arose. Thank you for your question. Please don't hesitate to ask in Brainly your queries.

Plants and animals that lack color are commonly called albinos. In corn plants, green (G) is dominant to albino (g). A student

Fittoniya [83]

(B) 25% GG, 50% Gg, and 25% gg

<u>Explanation:</u>

Given:

Green is dominant and is coded by G

Albino is recessive and is coded by g

Two corn plants that are heterozygous for color are crossed.

The heterozygous condition of the plant would be Gg.

The cross is shown in the table attached.

According to the punnett square drawn,

The genotypic ratio is 1 : 2 : 1 (GG : Gg : gg)

= 25% GG , 50% Gg , 25% gg

Phenotypic ratio = 3 : 1 ( green : albino)

= 75% green, 25% albino

Which of the following terms describes the distribution of a particular allele within a population

enot [183]

<span>The answer is allelic frequency. This is also the fraction of a particular allele of a gene in the population. Allelic frequency in a population of diploid individuals is calculated using the Hardy Weinberg equation of p2 + 2pq + q2 = 1. Allelic frequency of all the alleles of the genes must add up to 1 (one).</span>

A paleontologist has recovered a bit of tissue from the 400-year-old preserved skin of an extinct dodo bird. The researcher woul

slava [35]

Answer:

c)polymerase chain reaction (PCR).

Explanation:

Because the paleontologist recovered only a bit of tissue and it is very old, it is very likely that the DNA in the sample is very small and part of it is degraded. Anyway, the paleontologist must first amplify the DNA sample to obtain many identical copies of the specific region of the DNA they want to compare. the above is done through a polymerase chain reaction (PCR).

Draw the structure of DNA aand write a short note about it.

artcher [175]

Answer:

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code.
