Describe the
functions of the cell membrane
and cell wall
Answer:
cell membrane: provides protection for a cell . It also provides a fix environment inside the cell and the membrane has several different fonctions . One is to transport nutrients into the cell and also transports toxic substance out of the cell.
cell wall: cell wall is a structual layer sorrounding some types of cells , just outside the cell membrane . it can be tough , flexible ,and sometimes riding. it provides the cell with both structual support and protection , and also acts as a filtering machine.
Eutrophication both hurts and helps
aquatic environments.
true
false
Answer:
False. Eutrophication is an enrichment of water by nutrient salts that causes structural changes to the ecosystem such as: increased production of algae and aquatic plants, depletion of fish species, general deterioration of water quality and other effects that reduce and preclude use”.

Explain how stem cell therapy helped Lucy break down deoxyadenosine
Answer:
It helped her fight off the stop protein, eventually helping her create more amino acids.
The stem cell therapy helped lucy break down deoxyadenosine as it helped her fight off the stop protein, eventually helping her create more amino acids.
What is amino acid?Amino acid has the organic compound containing both an amino[tex](-NH2)[/tex] and a carboxylic acid [tex](-COOH)[/tex] functional group. The component of amino acid not contained in starch is that amino acids contain nitrogen but not starch.
On the other hand, starch has a carbohydrate molecule made up of monomers called monosaccharides. The monosaccharide is a long chain of carbon, hydrogen and oxygen atoms. This suggests that the major structural difference between amino acids and starch has that amino acids contain nitrogen but not starch.
There are several types of protein such as structural protein, transport proteins, antibodies, contractile proteins, hormonal proteins, and enzymes.
Therefore, The stem cell therapy helped lucy break down deoxyadenosine as it helped her fight off the stop protein, eventually helping her create more amino acids.

A population of birds eats nuts and seeds. Some birds have larger beaks, and some have smaller beaks. A pair of birds usually produces four or five offspring each year. After several yeaers of little rain, the seeds became larger and larger. The birds with larger beaks were better at cracking these seeds. After several generations, the average beak size in the population increased. Bird beak size increasing after several generations is: a. decent with modification. b. variation. c. overproduction. d. adaptation
As far as I can tell, the answer would be D. Adaptation. The birds are evolving to adapt to their environment, and as such, their beaks are getting larger to crack larger seeds.

A plant and an animal are both living things. According to the Cell Theory, what can you conclude about these two
very different organisms? SC.912.L.14.1
Plants have cells but animals do not
They are both made of one or more cells.
They both come from the same kind of cell.
O They both come from a non-living organism.
Answer:
They are both made of one or more cells.
Explanation:
A plant and an animal are both living things. According to the Cell Theory, what we can conclude about these two very different organisms is that they are both made of one or more cells.
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Generally, cells have the ability to independently replicate themselves.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles and they include nucleus, cytoplasm, cell membrane, golgi apparatus, mitochondria, lysosomes, ribosomes, chromosomes, endoplasmic reticulum, vesicles, etc.

This question may be completed independently or as a group exercise. You have learned that humans have 46 total chromosomes, and chimpanzees have 48 total chromosomes. Use other textbooks in biological anthropology and biology (or reputable online resources) to find the number of chromosomes in other organisms. Give an organism with considerably more chromosomes than humans. Give an organism with considerably fewer chromosomes than humans. Did your findings surprise you
Answer:
In comparison to humans, there are more chromosomes in the Hermit crab that is 127 pairs of chromosomes for a grand total of 254 and in Myrmecia pilosula has fewer chromosomes than humans.
The complexity of an organism or how advance is an organism has nothing to do with the number of chromosomes it had. The chromosome number is subject to change over time. Human ancestors had more chromosome numbers as compared to now but they are not advanced to us.

The table below Anton Leeuwenhoek devised a primitive microscope to observe a sample of his tooth scrapings. How did this help contribute to cell theory?
It helped to show that cells cannot function independently.
It helped to show that some bacteria can swim like fish.
It helped to show that some bacteria are just one cell.
It helped to show that cells can be created from thin air. shows the average wind speeds of four hurricanes in Florida.
Answer:
The correct answer is - option C.
Explanation:
Anton Leeuwenhoek observed the presence of organisms in his tooth scratch or scrapings under the primitive microscope made by himself. At that time there was no knowledge about the bacteria and he named these small creatures as animalcules. These animalcules were bacteria actually.
These creatures were single-cell organisms and able to perform the function as an entity and postulate that bacteria is a single which is a fundamental unit of function and structure of all living organisms.
