Answer:

The right answer to this question is: different codons sequences

Explanation:

The production of a protein is a little bit complex, it all starts on the nucleus of a cell, with the polimerase RNA reading a single ribbon of DNA, making new base pairs, matching them and changing Thymine to Uracil. After that, outside the cell, this mRNA will be read in the ribosome again, but now specifically, to one function, based on codons. Codons are a sequence of 3 nucleotides, but they're not random, it depends of what the body needs to survive.

That's why there's so much variation, for example, we don't have the same needs as a butterfly, or a shark, they produce different codons and by that way they can develop their characteristics.

What are the three types of homologies and the definitions?

olya-2409 [2.1K]

Answer:

hope this helps..

Explanation:

Dependent on the level of comparison four types of homology are defined: ( 1) Iterative ( = serial = homonomy), (2) ontogenetic, (3) di- or polymor- phic, and (4) supraspecific homology. ... Scientists have recently been paying renewed attention to the homology question.

Homology is the study of likeness, the similarity between species that results from inheritance of traits from a common ancestor. The study of similarities is broken up into three main categories: structural, developmental, and molecular homology.

(GIVING BRAINLIEST!!)

andrey2020 [161]

Answer:

Hurricanes are large, swirling storms. They produce winds of 119 kilometers per hour (74 mph) or higher. That's faster than a cheetah, the fastest animal on land. Winds from a hurricane can damage buildings and trees.

tornado is a violent rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of up to 300 mph. They can destroy large buildings, uproot trees and hurl vehicles hundreds of yards. They can also drive straw into trees.

Earthquake is a term used to describe both sudden slip on a fault, and the resulting ground shaking and radiated seismic energy caused by the slip, or by volcanic or magmatic activity, or other sudden stress changes in the earth.

A flood is an overflow of water that submerges land that is usually dry. In the sense of "flowing water", the word may also be applied to the inflow of the tide. Floods are an area of study of the discipline hydrology and are of significant concern in agriculture, civil engineering and public health.

Wildfires are fires that burn out of control in a natural area, like a forest, grassland, or prairie. They often begin unnoticed. They spread quickly, and can damage natural resources, destroy homes, and threaten the safety of the public and firefighters. Humans cause most wildfires.

zalisa [80]

Answer:

The nervous system is composed predominantly of neural tissue.

Explanation: Anatomist study anatomy, the study of the structure of organisms or their parts. By observing the structure of the nervous system, anatomist will tell that it is composed predominantly of neural tissue. So, he observed the structure of one part of an organism.
