Answer:
The main components that creates the hydrophobic and hydrophilic regions of the plasma membrane are phospholipids containing hydrophobic fatty acids tails.
Explanation:
Phospholipids are the main component of the cell membrane —lipid bilayer— and responsible for its selective permeability. Each phospholipid is composed of one glycerol molecule, which forms the head, and two fatty acid tails, plus one phosphate molecule.
In the lipid bilayer, the phospholipid heads are oriented towards the surface, while the tails are located inside, allowing interaction with both polar and apolar molecules.
The hydrophilic regions of the membranes are in contact with the liquids of the extracellular and intracellular spaces, while the hydrophobic region is inside the membrane, limiting the passage of polar molecules or ions.
The other options are not correct because:
a. Cholesterol molecules are part of the membrane, but are not responsible for the hydrophobic and hydrophilic regions.
b. Carbohydrates for cell recognition do not determine membrane permeability.
c. Glycolipids, like integral proteins, are part of the membrane, but do not determine the polarity of the regions.
This organelle modifies and labels proteins so they will be working properly and arrive at the correct destinations? so whats the answer?
Answer:
[tex]\boxed {\tt Golgi \ apparatus}[/tex]
Explanation:
After a protein is produced on a ribosome it is sent to the endoplasmic reticulum. Here, proteins fold and then are sent to the golgi apparatus.
In this organelle, proteins are modified and labeled. Sugar groups (modifications ) and tags/signals (labels) can be added. From the golgi apparatus they are sent to different destinations or secreted.
So, the correct answer is Golgi apparatus.
Golgi apparatus
The Golgi apparatus, which is usually situated near the nucleus, receives proteins and lipids from the ER, modifies them, and then dispatches them to other destinations in the cell. Transport from the ER to the Golgi apparatus—and the Golgi can either move onward through the Golgi stack or, if they contain an ER retention signal, be returned to the ER; proteins exiting from the Golgi are sorted according to whether they are destined for lysosomes (via endosomes) or for the cell surface.
If you took a 20-foot tree and hammered a spike into it 3-feet above the ground, how high would that spike be 30 years later when the tree is 100 feet tall? and why?
Answer:
The spike will remain at 3-feet above the ground in 30 years time because the spike does not increase in height as the tree does.
Please find the explanation below
Explanation:
Living things including the trees stated in this question are capable of growth (in height and girth). According to this question, a spike is hammered into a tree base at 3-feet above the ground level. However, after 30 years, the tree grows to 100 feet but the spike will remain at 3-feet above the ground.
This is because the spike, which is naturally incapable of growth, will not grow alongside the tree. A plant (tree) undergoes growth at its apices or meristem i.e. the tree will elongate from the tip and not any other part. Hence, the tree will grow and leave the spike at its initial level.
Differentiate the 2 types of Natural Resources.
Answer:
They are....
Explanation:
Biotic and Abiotic --->
*Biotic is all living things such as plants, and animals
*Abiotic is all Non- living things such as water, glass, oil, etc
Hope this helps!
The two types of natural resources are biotic and abiotic. Biotic resources are ones derived of organic origins, or may be grown, that are gathered from the biosphere. Abiotic resources are nonliving resources, like metals, water, or oil.
I hope this answers your question! Happy learning, friend :)
where does the energy for animals needed to live come from?
Answer:
the energy that they need comes from the food they eat
Explanation:
the animals get the energy they need from food that they eat.they eat the food and the food they eat givesthem energy becuase the thing they ate has energy from what they eat so it gives their energy to the one eating it.

help pleaseeeeeeee
Answer:
None of the above
Explanation:
The scientific name of the walrus is Odobenus rosmarus.
Odobenus is the genus name. Rosmarus is the species name.
They are in the phylum chordata , class mammalia , order carnivora, and family odobenidae. However, these are not included in the scientific name.
Therefore, none of the answer options are correct

Which ion builds up inside the membranes of the chloroplast?
Answer:
The innermost matrix of chloroplasts, called the stroma, contains metabolic enzymes and multiple copies of the chloroplast genome. Chloroplasts also have a third internal membrane called the thylakoid membrane, which is extensively folded and appears as stacks of flattened disks in electron micrographs.

do you think a hand-crank flashlight would be a good energy system for the rescue workers? Why or why not?
Answer:
No.
Explanation:
No, hand-crank flashlight would not be a good energy system for the rescue workers because the light turns on by applying muscle force on the hand-crank flashlight and after that, the device convert muscle force into electric energy and the light turns on and we know that the rescue worker have a tough job which requires both hands so this hand-crank flashlight is not useful to him.
Why did the narrator use the phrase "fit together like puzzle pieces" to describe how the cells of a developing human
embryo form a human face?
Answer:
The narrator uses that phrase because the pieces of the skin and face feathers have to come together as one to create a human head so they would be fitting together like puzzle pieces.
Explanation:
Answer:
The human face doesn’t form all at once. It requires many divisions of cells. As the cells divide, they eventually piece together to form a human face.

and
What macromolecules can be found in plant cells
Answer:
ANIMALS: There are four major classes of biological macromolecules (carbohydrates, lipids, proteins, and nucleic acids), and each is an important component of the cell and performs a wide array of functions. Combined, these molecules make up the majority of a cell's mass.
PLANTS: The three main classes of macromolecules found in plants are thus proteins, polysaccharides and nucleic acids. However, mixed polymers are also known. such as the glycoproteins, which contain both sugars and amino acids in covalent linkage.
The macromolecules found in animal cells are carbohydrates, proteins, lipids, nucleic acids, and water. Each of these macromolecules has specific functions in the body of kingdom Animalia.
What are Macromolecules?Macromolecules may be defined as a molecule that contains a very large number of atoms that are held together by specific bonds.
The macromolecules found in animal cells are polysaccharides, proteins, nucleic acids, water, and some types of mixed polymers.
All such macromolecules perform specific functions in the structure of kingdom Plantae and meet the need for metabolic activities.
Therefore, it is well described above.

Name and describe 3 ways objects can travel across a membrane. Include what types of objects (H2O, sugar, ect) are moving across the membrane for each way.
Answer:
Osmosis - water
Ions - diffusion
Large proteins - endocytosis
Explanation:
Ions and small molecules can cross the cell membrane by simple diffusion, where they move from a high concentration to a low concentration, down a concentration gradient.
Osmosis is the process whereby water travels across a semi-permeable membrane from a high concentration to a low concentration.
Larger cargo can cross the membrane through a process called endocytosis, where the membrane engulfs the particles and brings them inside the cell, encased in a vesicle.
