Explanation:

all cells do not contain a nucleus

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.

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.

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

Explanation:

Water is extremely valuable to all living things. It is especially important for plants to perform photosynthesis which is one of the smallest most valuable biochemical mechanisms known to life, in addition, plants are the main source of nutrients for many creatures. Without photosynthesis, plants would not be able to produce oxygen. In addition, plants are classified as producers, the most basic level of the flow of energy in every ecosystem and are the main reason energy from the sun can then be converted into usable energy for primary consumers, secondary consumers, and tertiary consumers. For humans, water is extremely important to keeping our bodies in homeostasis while the billions of chemical reactions take place in our bodies in just minutes. A human can not live without water for more than three to four days. If there was a deficiency of water both plants, animals, and humans would be greatly affected. Without water, plants would not grow, so no conversion CO2 to 02 and harnessing energy from the sun. Next animals that depend on both water and plants would have a decrease in population. Followed by the depletion of all else consumers. You remove a resource this valuable and there is no coming back.

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.

"Variation in a population leads to increase in likelihood of success during environmental changes." is the answer because if there were a larger amount of species in the/ a(n) area, then the probability of them going extinct is likely to decrease.

It's like if you want ice in your drink!

If you have 3 ice cubes in you drink then it is likely that the ice cubes will disintegrate, and not cool your drink, but if you have a larger amount of ice cubes, then not only is your drink chilling, but your ice cubes will still be there, but smaller.

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.

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:

4: It is a measure of how far an object moves in a certain time.

Explanation:

Hope this helps

Answer:

All living organisms are classified into groups based on very basic, shared characteristics. Organisms within each group are then further divided into smaller groups. These smaller groups are based on more detailed similarities within each larger group. This grouping system makes it easier for scientists to study certain groups of organisms. Characteristics such as appearance, reproduction, mobility, and functionality are just a few ways in which living organisms are grouped together. These specialized groups are collectively called the classification of living things. The classification of living things includes 7 levels: kingdom, phylum, classes, order, families, genus, and species .

Answer:

This question is incomplete

Explanation:

However, as described in the question. each cell organelle has specialized function that assists the cell carry-out it's own function as a whole. Cell organelles include cell membrane, smooth and rough endoplasmic reticulum, vacuole, golgi complex, lysosomes, nucleus, mitochondria, chloroplasts among others.

Of these cell organelles, only three were mentioned in the question

Nucleus: This houses the chromosome which stores genetic material. This organelle is found in plant and animal eukaryotic cells. Indeed, eukaryotic organisms are sometimes described as organisms that have well defined nucleus.

Mitochondria: They are found in most plant and animal eukaryotic cells. They are usually referred to as the power house of the cell as they provide energy-rich chemical compounds (called ATP) for the cell's activities.

Chloroplasts: These are cellular structures/organelles that are found only in  green plants - they are cellular machinery for photosynthesis in plants. They also contain the green pigment called chlorophyll which is responsible for the green colour of green plants.

The type of the cell in which the organelles mentioned in the question are listed above.
