Explanation:

Genetic material or Nuclear material can be found in the cell either  in "nucleus" a membrane bound organelles or found in the cytoplasm. This is the major difference between prokaryotic and eukaryotic cell.

In prokaryotic cell the genetic material that is DNA, and RNA is not present in the nucleus as there is no body like nucleus for instance figure 2 and 3 whereas in eukaryotic organisms it is present in a nucleus like in figure 1 and 4.

Answer:

1. eukaryotic cell

2. prokaryotic cell

3. prokaryotic cell

4. eukaryotic cell

Answer:

b. Patients do not receive harmful or ineffective medication.

Explanation:

on edge

Tissue culture is used to treat cancer patients, as this procedure does not use any harmful or ineffective medication on the patients unlike the other treatment options. Thus, the correct option is A.

Tissue culture is the process of growth of tissues or cells in an artificial medium that is separate from the parent organism. This technique is also known as micropropagation method. It is typically facilitated via the use of a liquid, a semi-solid, or a solid growth medium, such as the broth or agar medium.

Tissue culture is used widely in science for the propagation of plants, in the study of medicines such as those related to cancer. Tissue culture can be used as a treatment option in cancer as this technique does not show any harmful or ineffective medication. The cultured tissues of stem cells can be used for replacement of infected cells or body parts.

Therefore, the correct option is A.

Explanation:

The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus.

is it ok if u could try and help me with my last question if so thx

Answer: convergent evolution

Explanation:

The similar shapes of fast swimming marine predators are an example of convergent evolution.

Convergent evolution shows how different species possess identical structures even though they evolve separately. Convergent evolution typically takes place with the organisms that are not really related.

An example of convergent evolution is the similarity that can be noticed in the wings or the flights of bats, birds, insects, etc

Answer:

The amount of light that a plant has determines how much the plant grows, plants need sunlight for photosynthesis, and photosynthesis is how they make food so if a plant has little to no sun it won't grow well.

Answer:

(See Below)

Explanation:

[1] Magma comes out of the rift valley.

[2] Magma cools to rock and hardens.

[3] Rock is pushed away as new rock is formed at MOR (Mid Ocean Ridges)

[4] Oceanic crust and continental crust meet at the trench.

[5] Oceanic crust bends down under the continental crust.

[6] Gravity pulls rock towards mantle.

[7] Rock melts to mantle.

Explanation:

Sea floor spreading is a process that occurs at mid ocean ridges,where new oceanic crust is formed through volcanic activity and then gradually moves away from the reach.

Answer:

Gene regulation can occur at any point during gene expression, but most commonly occurs at the level of transcription (when the information in a gene's DNA is transferred to mRNA). Signals from the environment or from other cells activate proteins called transcription factors.

Explanation:

Gene regulation can take place at any stage of gene expression, although it often happens during transcription when the data from a gene's DNA is converted to mRNA.

Proteins known as transcription factors are activated by signals from the environment or from other cells.

Limiting the amount of mRNA that is generated from a certain gene regulates transcription.

Eukaryotic gene expression is regulated by the nucleus-based mechanisms of transcription and RNA processing and the cytoplasm-based activities of protein translation.

Therefore, the translation of mRNA into proteins is regulated by post-transcriptional processes, which constitute the second level of regulation.

Kingdom Animalia

Explanation:

Kingdom Animalia is one of the seven kingdoms living organisms are classified into. The Kingdom contains organisms called ANIMALS. They are eukaryotic i.e. possess a membrane-bound nucleus. Animals are heterotrophic i.e. they rely on other organisms for their source of energy (food).

In order to break down this food via metabolism, animals need oxygen to do so. This process is called respiration, and it yields energy in form of ATP, which is used by their cells to carry out cellular functions. Therefore, a heterotrophic multicellular organism that relies on oxygen to metabolize its food belongs to KINGDOM ANIMALIA

hydrogen bonds between water molecules. An attraction between the positive end of one molecule and the negative end of another molecule describes each hydrogen bond.

Water is amphoteric in nature because it serve as both acid and a base, highly viscous in nature due to the presence of a force of attraction  between molecules.

Water is participate in Redox reaction as it help in release of dihydrogen molecules easily, the dielectric constant  is also high, form the connections with other chemical compounds known as hydrates.

The temperature below   4 degrees Celsius the water  ordinarily behaves, when it is cooled further, its unusual properties of water molecule are being observed.

During cooled condition,  the density of water can also slowly increases and further cooled down leads to decrease in the density of water and the expansion of matter  called as the anomalous property of water.
