Which type of organelle is primarily involved in the synthesis of oils, phospholipids, and steroids?
a.
b. ribosome
c. lysosome
d. smooth endoplasmic reticulum
e. mitochondrion f. contractile vacuole?

Answer:

Prokaryotes are a simple, single-celled species, which are devoid of membrane-bound organelles or a nucleus. The cell composition of prokaryotes can differ, however, the majority of organisms exhibit many basic constituents. Prokaryotes have a plasma membrane or cell membrane, which functions as a safeguarding layer.  

They also possess a tough cell wall for supplementary protection and support. The cells of prokaryotes possess ribosomes that are the molecules, which produce proteins. Their genetic substance is in the nucleoid that is the part where DNA thrives. Supplementary rings of DNA known as plasmids float freely in the cytoplasm.  

Apart from this, some of the prokaryotes exhibit flagellum or pilus to assist them in movement. Some of the prokaryotes exhibit a capsule exterior to their cell walls. The storage of nutrients can also differ, however, many prokaryotes utilize stowage granules in their cytoplasm.  

Answer: The most dominant form of plants found in Triassic Era was Gymnosperms. They lack a protective covering on seed and did not produce flower. The outer coating of seed is absent in Gymnosperms. There were no angiosperm in that era and the dominant form was angiosperm only. This was because of the climatic conditions at that time that the survival of any other plants other than gymnosperm was not possible.

Final answer:

Uniformitarianism is the geological principle stating that the same processes that operate now have always operated in the Earth's past and are responsible for shaping Earth's geological features. Option B is correct .

Explanation:

The principle that suggests all geological processes have occurred in the same manner throughout Earth's history is known as uniformitarianism. This concept was first proposed by James Hutton, a Scottish geologist, and later popularized by Charles Lyell in the 19th century. It contradicts other beliefs such as catastrophism, which posits geological features result from sudden, substantial events. Uniformitarianism states that the slow and continuous processes we observe today, like erosion and sedimentation, are the same ones that shaped Earth's surface in the past. Therefore, the correct answer to the student's question is B) Uniformitarianism. This principle suggests that changes in the Earth's surface are the result of slow and consistent processes rather than sudden and catastrophic events. For example, valleys formed by rivers wearing through rock over long periods of time is an example of the gradual change that is consistent with uniformitarianism.

Explanation: i just did the test so this is right

The correct answer is , Vitamin D.

It is a fat-soluble vitamin with a long history of helping the body retain and absorb calcium and phosphorus, both of which are essential for bone development.

Additionally, research in the lab demonstrates that vitamin D helps lessen inflammation, manage infections, and slow the growth of cancer cells. Scientists are actively researching additional potential activities for vitamin D, which has receptors in many bodily organs and tissues and suggests crucial roles beyond bone health.

Though certain foods have been fortified with vitamin D, very few foods actually contain it naturally. Because it is challenging to consume enough vitamin D through diet, taking a supplement is the best option for the majority of people.

Therefore, The correct answer is , Vitamin D.

Answer:

Mitochondria

Explanation:

Mitochondria are organelles of a eukaryotic cell also known as 'power house' of the cell as it produces energy currency of the cell that is ATP. They are present in cytoplasm, not in the nucleus. It converts the energy obtained form the food we eat to the energy that is responsible for running a range of biological processes.

The answer is a normal fault. The hanging wall moves downward relatively to the foot wall. These classification of faults place fresher or low-graded rocks above the old or high-graded rocks. Normal faults may be found in different countries around the globe.

Final answer:

Balancing a chemical equation is vital because it adheres to the law of conservation of matter and allows for the precise stoichiometric relationships between reactants and products. This process ensures equal numbers of atoms for each element on both sides of the equation and is crucial for accurately determining reactant and product quantities.

Explanation:

Proper chemical equations should be balanced. Writing balanced reactions is a chemist's way of acknowledging the law of conservation of matter, which states that matter can neither be created nor destroyed in an isolated system. This principle is a fundamental concept in Chemistry and is crucial for the proper understanding of chemical processes.

In order to balance a chemical equation, it is important to understand the law of conservation of mass. This law signifies that the quantity of each element involved in a chemical reaction must remain unchanged from the reactants to the products. Therefore, an important exercise is the process of balancing a chemical equation, which consists of placing the correct coefficients before each of the reactants and products so that equal numbers of each kind of atom are on both the left and right sides of the equation.

A balanced chemical equation provides not only the identities of the reactants and products involved in the chemical change but also their stoichiometric relationship—the quantitative assessment of the relationships between the amounts of substances consumed and produced by the reaction. This stoichiometric relationship is crucial when determining the amount of one reactant required to react with another, or to yield a given amount of product.
