Answer:

False

Explanation:

Uncertainty is one of the biggest parts of science.

There are many things that have been uncertain in science, and there are still lots of things for us to discover.

Uncertainty in science is the reason why experiments are done and why hypotheses are made.

Uncertainty IS a part of science, and is a very important part, so the statement is false.

Answer:

false

Explanation:

scientists are uncertain all the time.

Answer:

Non-living things.

Explanation:

The phosphorus cycle is the biogeochemical cycling of phosphorus, a very important element of living things, between the living and nonliving parts of our world.

Answer:

Dead things.

Explanation:

Also water, rocks, and the atmosphere.

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:

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:

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:

Hey mate,here is your answer. Hope it helps you

Explanation:

Local winds are basically of two types:-  

The sea breeze is a thermally produced wind blowing during the day from the cool ocean onto the adjoining warm land. It is caused by the difference in the rates of heating between the land and the ocean. The bigger the difference in temperature, the stronger the wind.

For example, hot land temperatures next to cold ocean temperatures will create a stronger sea breeze than land temperatures that are only a little bit warmer than the ocean temperatures. So during the afternoon when the temperatures differences are normally at their highest, the sea breeze will normally be at its strongest, bringing relief from the heat to beachgoers.

This process also works in reverse at night. Only this time it is known as the land breeze. The land breeze is a coastal breeze at night blowing from the land to the ocean. It is caused by the difference in the rates of cooling of the land and of the ocean. Once again, the bigger the difference in temperature between the two, the stronger the wind.

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:

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
