Answer:
Jovian planets are larger, further from the sun, rotate faster, have more moons, have more rings, are less dense overall and have denser cores than terrestrial planets. Jovian planets also have gaseous atmospheres, with the main gases being hydrogen and helium.
2. what are the differences between Mitosis and meiosis
Answer:
The differences between Mitosis and meiosis is Mitosis involves the division of body cells, while meiosis involves the division of sex cells. The division of a cell occurs once in mitosis but twice in meiosis. Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis

The process of photosynthesis adds oxygen to the atmosphere. Option C is correct for the given statement. In the atmosphere, nearly 21% oxygen is present.
What is the gas constituent of the atmosphere?In the atmosphere, different gases such as oxygen, nitrogen, carbon dioxide, and water vapour are present. These differ in composition, with oxygen accounting for 21%, nitrogen accounting for nearly 78%, and carbon dioxide accounting for less than 1%.
The oxygen is produced by the process of photosynthesis that is undertaken by green plants. The phytoplankton, algae in aquatic habitats, and plants of the terrestrial ecosystem do photosynthesis because of the presence of chloroplasts.
This oxygen is used by animals and plants for cellular respiration. Others are incorrect options because forest fires increase carbon dioxide in the atmosphere, animals take oxygen from the atmosphere, and rock weathering does not add oxygen.
As a result, option C is the correct answer because photosynthesis produces oxygen for the atmosphere.

2. How can a genetic mutation be beneficial to an organism?
3. What are some other evidences of evolution discussed in this unit?
Answer:1.Selection of the dark-colored moths over light-colored moths after industrial evolution is an example of directional selection while selection of alpha males and “sneaking” males over intermediate males in a lobster population is an example of disruptive selection.
2.organism in which they occur. They are called beneficial mutations. They lead to new versions of proteins that help organisms adapt to changes in their environment. Beneficial mutations are essential for evolution to occur.

Explanation:
A difference between a Class I and a Class II tRNA synthetase is (select all that apply):
a. the Class I synthetase reaction requires a transesterification reaction not necessary in the Class II reaction.
b. the Class I synthetase uses the 2' OH of the 3' end of the tRNA as a nucleophile and the Class II uses the 3' OH.
c. the Class I synthetase requires ATP as a cofactor and the Class II does not.
d. the Class II synthetases are typically monomeric, whereas the Class I enzymes frequently function as multimeric protein complexes.
Answer:
Option b is the correct answer.
Explanation:
The 2' OH of each 3' end of the tRNA is used as a nucleophile by Class I synthetase, whereas the 3' OH is used by Class II.
The Class I aminoacyl-tRNA synthetase attaches amino acids to the 2'-OH group of the tRNA's 3'-end ribose residue, whilst the Class II synthetase attaches amino acids only to the 3'-OH group of the tRNA's 3'-end ribose residue. Both Class I and Class II enzymes conduct the transesterification process and the need of ATP.
What we have is option d is incorrect because, Class I enzyme is typically monomeric, while the Class II enzyme is dimeric or multimeric in nature.

Is a pig crossed with a chimp possible, I just read an article about this and the person who had the idea was someone with the last name MCkarther PH.D. it made the news.
Answer:
The cross between two different species is called hybridization. The truth is that, for hybridization to occur, the species in question must have a certain kinship with each other, that is, they must belong to the same family of animals. An example is the cross between tigers and lions, pigs and wild boars, donkeys and donkeys, etc. Now, if there is no such familiarity between species, the truth is that hybridization will not be possible, which is the case of pigs and chimpanzees with each other.
