The cell is the basic structural, functional, and biological unit of all living organisms.
The structural and essential component of life is the cell. Cell biology is the study of cells, including their fundamental makeup and the purposes of each of their organelles.
The first biologist to discover cells was Robert Hooke. Cells make up every living thing. They could consist of several cells (multicellular) or just one cell (unicellular) (multicellular).
The tiniest cells known to science are mycoplasmas. All living things are constructed from cells. They give the body structure and turn the nutrients from the diet into energy.
Complex cells conduct a variety of tasks for an organism's parts. They resemble masonry bricks in that they come in a variety of sizes and forms.

The concept of Globalization has ensured that economic and environmental conditions in different countries are related and linked.
When the particles are equally spaced apart they have reached:
A. Hypertonicity
B. Dynamic Equilibrium
C. Homeostasis
D. Osmolarity
Answer:
B. Dynamic Equilibrium
Explanation:
Since the molecules are still in motion, but an equilibrium has been established, the end result of molecular diffusion is called a "dynamic equilibrium". The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane. At equilibrium, the movement of molecules does not stop.
Answer:
B. Dynamic Equilibrium
Explanation:
When the particles are equally spaced apart they have reached the dynamic Equilibrium.

which of the followimg could be reasons why popultion sizes may reach and maintaim plateaus? choose the three that apply
Will mark as brilliant answer
Answer:
Below :D
Explanation:
So basically, this question is asking what will cause a species' population to reach a point where it stops increasing.
Lets think about what can cause a lack of increase?
A decrease can cause this.
Or a slow in the rate of increase.
Now lets look at our selectable answers and see if any of them would fall under these two things.
First up is fewer deaths.
Well, fewer deaths basically means less of a decrease in population.
This is the opposite of decreasing the populatin count, and would instead raise it.
Next we have a limit in food supply.
This would cause a organism to starve and die.
So this would cause a decrease in population count.
So B is one of the answers
Next up is competition with other species.
When two species compete for a sort of resources, one massivly dies out due to outcompetion, and loses the resources needed to survive.
So this would also cause a large decrease in population count.
This makes C one of the answers
Next is increase in birth rates.
This would cause more organisms to be born of a species, basically increasing the population count.
This is the opposite of a decrease in population.
Next we have competition for space.
This is very similar to answer C, and the outcompeted species dies out due to lack of space.
So E is one of the answers
Now, the next answer seems viable, because major storms can kill off organisms, like hurricanes, earthquakes, and volcanos for instance.
However, as seen in many organisms over history, while these major storms kill of organisms, they can recover.
So although major storms decrease populations, they dont actually limit them.
In the end:
B is correct
C is correct
E is correct

Which organ releases the hormone insulin in order to regulate the level of blood sugar in the body?
Gall Bladder
Liver
b. Pancreas
d. Spleen
Answer:
Pancreas
Explanation:
Insulin is an essential hormone produced by the pancreas.
Answer:

Which of the following accurately describes covalent bonds?
A. Covalent bonds are formed when atoms share one or more
electrons.
B. Covalent bonds are formed when atoms transfer one or more
protons.
C. Covalent bonds are formed when atoms share one or more
protons.
D. Covalent bonds are formed when atoms transfer one or more
electrons.
Answer:
A
Explanation:
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms. These electrons are simultaneously attracted by the two atomic nuclei. A covalent bond forms when the difference between the electronegativities of two atoms is too small for an electron transfer to occur to form ions.
Answer: The answer is A Covalent bonds are formed when atoms share one or more electrons

different
Answer:
Identical
Explanation:
Binary fission is a form of asexual reproduction. This is when only one parent is involved in creating offspring. Since there is only one parent, two sets of DNA cannot be combined into a new offspring; so, it must be identical.

PLEASE HELP!!!! You are a scientist tasked with writing a journal article on the evolution of alligators. In 3–5 sentences, describe the different forms of evidence you might use to analyze the evolution of alligators.
Answer:
The first alligator ancestors evolved about 245 million years ago.
Explanation:
The first alligator ancestors evolved about 245 million years ago due to change in the environmental condition. crocodilians appeared about 80 million years ago during the Cretaceous period. Modern alligators has experience less changes which is closely related to their ancient ancestors and look much like to their relatives that exists about 80 million years ago. The main reason for the change in the body structure of alligator is due to change in environmental condition.
The evolution of alligators can be analyzed by sequencing samples of different species and then producing a bioinformatic analysis.
What is evolution?Evolution means descendence with some class of modification in offspring (phenotypic, genetic, etc).
Evolution can be analyzed by sequencing and comparing the linear order of nucleotide sequences between different species.In conclusion, the evolution of alligators can be analyzed by sequencing samples of different species and then producing a bioinformatic analysis.

Which of the following is NOT a
piece of evidence that Darwin
used to support his theory of
evolution?
A. fossil record
B. similarities among different species
C. the amount of shared DNA between species
Fossil record is not a piece of evidence that Darwin used to support his theory of evolution.
What is the theory of evolution?Evolution is the process of change in all forms of life over generations, and evolutionary biology is the study of how evolution occurs. Biological populations evolve through genetic changes that correspond to changes in the organisms' observable traits.
Darwin proposed that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor. In this model, each species has its own unique set of heritable (genetic) differences from the common ancestor.
The current evolutionary theories can be categorized as Darwinism and Lamarckism. Charles Darwin theorized Darwinism. He explained his theory of natural selection in his book, On the Origin of Species.

Maja puts a hockey puck onto ice. After a while the temperature of the hockey puck decreases. What happens to the molecules of the hockey puck when the temperature of the puck decreases?
Answer: The energy of the molecules in the hockey puck decreases.
Explanation:
When the temperature of the hockey puck decreases, then the energy of the molecules in the hockey puck decreases as well.
In this scenario, when the temperature of the hockey puck decreases, then the hockey puck will gain heat molecules and the cold energy of the molecules that are in the hockey puck will reduce.
