The diffusion of water molecules in and out of cells is very common.
Which of the following is the process by which water moves across a
membrane, from an area of high concentration to low concentration,
without the use of energy? *
osmosis
hydrolysis
photosynthesis
cyclosis
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.

10. Vestigial structures
Are dangerous and should be removed.
Are fully functional structures in a species.
Are usually present, but are no longer functional.
Have been completely eliminated from the species.
Answer:
Are usually present, but are no longer functional.
Explanation:
Vestigial structures are "evolutionary remnants". They are anatomical features that were once important throughout the organism's evolution, but now have no function. However, they aren't harmful either, so there has been no selective pressure for them to be removed via evolution.
Good examples in humans are the tail bone, wisdom teeth, and the appendix.
What is the function of the nucleus of a cell.
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.

How does ultraviolet radiation harm living things?
Answer:
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.

A.75N
B.75 kg
C.0.013 kg
D.768 kg
Which is the answer?
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

Every cell in your body contains organelles (structures that have specific functions). Just like organs in the body, each organelle contributes in its own way to helping the cell function well as a whole. The nucleus, mitochondria and chloroplasts are all organelles. Some organelles are found only in some cell types.
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.

Describe an example of acceleration and explain how velocity is changing
The velocity is changing because the acceleration is present which is non-zero.
What is acceleration?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 strength of the net resultant force, which is directly proportional to the sum of all external forces exerted on that item;Depending on the components used to create it, an object's mass is inversely related to its magnitude.The velocity is changing because the acceleration is present which is non-zero.

Why do the plant and animal cells SHARE some levels of classification?
Why are some levels of classification DIFFERENT?
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 .

Question 17 of 30 What is a disadvantage of using nuclear power? A. Nuclear power produces very little energy. B. Nuclear power is very expensive. C. Nuclear power produces greenhouse gases. D. Nuclear power produces radioactive waste. SU
A disadvantage of using nuclear power is D. Nuclear power produces radioactive waste.
What is nuclear power?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.

1.Water covers 70 percent of the earth's surface and supports life on the Earth. Explain the statement 2.Why do we need to manage our resources? { i need the answer before 4 pm please help!}
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.

Which organism turns nitrogen back into nitrogen gas?
A. denitrifying bacteria
B. nitrogen fixing bacteria
C. decomposers
D. nitrifying bacteria
Answer:
b
Explanation:
part of the nitrogen cycle
Denitrifying bacteria turns nitrogen back into nitrogen gas. The correct option is A.
What is nitrogen fixation?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.
