Answer: a

Explanation:

Answer:

A

Explanation:

Answer:it coordinates cell activities like protein synthesis and cell division. Anatomically the nucleus is made up of several components: nuclear envelope, nuclear lamina, nucleolus, chromosomes, nucleoplasm are some of these components.

Explanation:

Answer:

The nucleus controls and regulates the activities of the cell and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm.

Explanation:

Answer:

Eukaryotes are organisms whose cells have a nucleus enclosed within a nuclear envelope. Eukaryotes belong to the domain Eukaryota or Eukarya; their name comes from the Greek εὖ and κάρυον. The domain Eukaryota makes up one of the domains of life in the three-domain system; the two other domains are Bacteria and Archaea. Eukaryotes represent a tiny minority of the number of living organisms; however, due to their generally much larger size, their collective worldwide biomass is estimated to be about equal to that of prokaryotes. Eukaryotes evolved approximately 1.6–2.1 billion years ago, during the Proterozoic eon.

Explanation:

Answer:

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... The nucleus is only one of many membrane-bound organelles in eukaryotes. Prokaryotes, on the other hand, have no membrane-bound organelles.

Answer:

The three tenets to the cell theory are as described below: All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.

Answer:

Cellular division

Explanation:

it's because abnormal production (mutations) causes leukemia

cellular division is most likely affected by this new drug in case of leukemia. Thus option D is correct.

Leukemia is a cancer related abnormal division in blood or blood-forming cells. It is other wise known as blood cancer.

The exact cause is not known, major risk factors are radiation exposure, chemotherapy for cancer, smoking, family history of leukemia, and exposure benzene.

Leukemia cells, do not clump to form tumor, due to this  leukemia is not diagnosed through imaging tests.

Common symptoms include pain in the bones, swollen lymph,, bleeding and bruising  nodes, feeling weak, fevers or night sweats etc.

Leukemias can be acute or chronic.

On the basis of cell type affected  four types of leukemia observed such as acute lymphoblastic leukemia (ALL), chronic lymphocytic leukemia (CLL), acute myelocytic leukemia (AML), and chronic myelocytic leukemia (CML).

Thus option D is correct.

Answer:

b

Explanation:

part of the nitrogen cycle

Denitrifying bacteria turns nitrogen back into nitrogen gas. The correct option is A.

Any natural or artificial process called nitrogen fixation causes free nitrogen, a relatively inert gas present in large quantities in the atmosphere, to chemically interact with other elements to generate more reactive nitrogen compounds like ammonia, nitrates, or nitrites.

Chemically, nitrogen fixation transforms atmospheric nitrogen into ammonia, which is ingested by living things.

In essence, nitrogen fixation transforms atmospheric nitrogen into a form that plants can use more easily.

Nitrate is transformed back into nitrogen gas by denitrifying bacteria, which then reenters the atmosphere. Runoff and fertilizer-related nitrogen enters the ocean, where it interacts with marine food webs.

Thus, the correct option is A.

Answer:A

Explanation:

Osmosis is the process; it is essentially diffusion, which is a spontaneous (no energy input required) process as applied to water.

----------------------------

Hydrolysis is incorrect; that describes a type of chemical reaction in which water breaks a chemical bond.

Photosynthesis is incorrect; that describes the complex process in which energy in light is converted into chemical energy.

Cyclosis is incorrect; that describes the movement of cytoplasm within a cell. There is no spontaneous, net movement of water across a concentration gradient.

The velocity is changing because the acceleration is present which is non-zero.

The rate of change of velocity of an object in a particular direction is known as acceleration. The acceleration is a vector quantity and its SI unit is a meter per second square. The acceleration is given as,

a = dv / dt

Where dv / dt is known as change.

According to Newton's Second Law, the amount of an element's acceleration is the joint result of two reasons:

The velocity is changing because the acceleration is present which is non-zero.

Answer:

B.75 kg

Explanation:

Given parameters:

Force on the object = 240N

Acceleration of the object = 3.2m/s²

Unknown:

Mass of the object = ?

Solution:

Force is the pull or push on an object. According to Newton's first law; it is mathematically expressed as;

     Force  = mass x acceleration

The unknown here is the mass, simply input the parameters and solve for it;

       240  = mass x 3.2

           mass  = [tex]\frac{240}{3.2}[/tex]   = 75kg

The mass of the object is 75kg

Ultraviolet (UV) photons harm the DNA molecules of living organisms in different ways. In one common damage event, adjacent bases bond with each other, instead of across the “ladder.” This makes a bulge, and the distorted DNA molecule does not function properly.

Explanation:

A disadvantage of using nuclear power is D. Nuclear power produces radioactive waste.

Nuclear power is a controversial topic, with proponents arguing that it is a clean and efficient source of energy, while opponents point to the risks of accidents and the dangers of radioactive waste.

One of the main disadvantages of nuclear power is that it produces radioactive waste. Radioactive waste is a byproduct of the nuclear fission process, and it can remain radioactive for thousands of years. This makes it difficult to store and dispose of safely. Another disadvantage of nuclear power is that it is expensive to build and operate nuclear power plants.
