False.
All sources of pollution do not come from human activities.
<h3>What are the causes of pollution?</h3>
There are some natural causes of pollution. When dangerous pollutants enter the air as gases, liquids, or solids, air pollution is formed. Although there are some natural processes that can produce air pollution, such as sulfur and chlorine gases from volcanic activity, smoke and ash from wildfires, dust storms, and biological degradation, manmade sources account for the majority of pollution in the atmosphere.
Burning fossil fuels for transportation, energy, and industry produces the majority of air pollution that is caused by humans. Carbon dioxide, nitrogen oxides, sulfur dioxide, volatile organic compounds (VOCs), and particulates are typical pollutants released by fossil fuel-burning engines. In addition to particles, carbon monoxide and carbon dioxide are produced by stoves, incinerators, and open burning.

The steps in translation are: The ribosome binds to mRNA at a specific area. The ribosome starts matching tRNA anticodon sequences to the mRNA codon sequence. Each time a new tRNA comes into the ribosome, the amino acid that it was carrying gets added to the elongating polypeptide chain.
The best answer is B.
The cells of a multi cellular organisms are called eukaryotic cells and have:
1. a membrane-bound nucleus
2. numerous membrane - bound organelles including the endoplasmic reticulum, Golgi apparatus, chloroplasts and mitochondria.
3. several rod-shaped chromosomes.
Because a eukaryotic cell's nucleus is said to be surrounded by a membrane, it is said to have a true nucleus. Organelles (meaning "little organ") have specialized cellular roles just like the organs of the body have specialized roles.
Answer:
FALSE. because why would something be wrong of it is supported by credible evidence, but if it stated the hypothesis along with the evidence and the evidence isn’t as credible then it could be true but only in that case.
Explanation:
Answer:
TT
All tall
Explanation:
If an organism is purebred, that means it is homozygous. That means, it contains two copies of the same allele (trait) at this particular gene. Lets denote the tall allele as T. That means the plant is TT, and purebred tall.
No matter what genotype (i.e. what 2 alleles) another plant has, the offspring will always be tall. That is because it will always inherit one T from the TT parent. Even if we cross it to a tt plant, all the offspring would be Tt. They would be heterozygous, but they would be tall.
