They killed there troops and this bad things to the USA government.
Answer:
See the answer below
Explanation:
A DNase is also known as deoxyribonuclease and it is an enzyme that catalyzes the degradation of deoxyribonucleic acid by cleaving the phosphodiester linkage in their structures. Thus,<em> if the RNA is treated with a DNase before the plants are exposed to it, it will not make any difference. The plants will develop the same types of lesions as if they have been exposed to the mosaic virus.</em>
Unlike DNase, RNase is a ribonuclease, an enzyme that is capable of carrying out catalytic degradation of ribonucleic acids. <em>This means that if the RNA is treated with RNase before the plants are made to be exposed to it, they will not develop the lesions because the RNA would have been degraded by the enzyme.</em>
A protease is an enzyme that degrades the structure of proteins. <em>Treating a RNA with protease will thus have no effect on the structure of the RNA. Exposing the plants to the protease-treated RNA will make no difference. The plants will still come down with the lesions as if they have been exposed to the virus. </em>

See the answer below.
Explanation:
The arrival of cacao beans in the factory can be likened to the transcription of mRNA using a DNA template.
Sorting of the best beans at the factory can be likened to splicing process. During splicing, the introns are removed from the newly synthesized mRNA and the exons are joined together. The introns represent the non-coding portion of the mRNA while the exons represent the coding sequence.
The checking of bags by quality control can be likened to the final proofreading of the mRNA after splicing before being transported to the cytoplasm where they are used to synthesize proteins.
The large truck that transports the cacao beans represent the transport proteins that transport the mRNA to the cytoplasm while the chocolate-producing company represents the ribosome which is the site of protein synthesis.
Answer:
Only plants with perfect flowers are capable of self-fertilization.
Explanation:
Self-pollination is the process that allows plants to fertilize themselves. This process is very beneficial when a plantation has plants with few flowers or when the plants are spaced far apart.
However, only plants with perfect flowers can self-fertilize. This is because for self-fertilization to occur, the plant needs to have flowers that present the male and female reproductive organs, which allows the same flower to produce pollen that will be sent to its own ovary. Only perfect flowers have male and female reproductive organs at the same time.
Answer:
The correct answer is a. Zygote
Explanation:
Edouard van Beneden was a zoology professor at the University of Liège whose worked showed how chromosomes are organized during gamete formation or during meiosis process.
During meiosis, the chromosomes number is reduced to half so each gamete contains half of the chromosome found in somatic cell and are called haploid cells. This reduction in chromosome number is necessary to bring the correct number of chromosomes in the zygote.
During fertilization, sperms fuse with eggs to produce a single diploid cell that is known as zygote. So the zygote has 46 chromosome in which half comes from sperm and half from the egg.
