Answer:
Water molecules will still be able to move across the cell membrane but at a slower rate.
Explanation:
D isn’t a sensible answer because Aquaporin is a protein with a role to regulate water transport. In its absence, of course there will be defects. And A is impossible due to the existence of active transport. (I also looked it up) (:
Answer:
Water molecules will still be able to move across the cell membrane but at a slower rate.
Explanation:
The aquaporin facilitates water passage, but water can still move across the membrane by osmosis. (osmosis requires no channel protein, but aquaporin makes diffusion faster).
True or False: Enzymes have an optimal or ideal pH level?
Answer:
All enzymes have an ideal pH value, which is called optimal pH. Under the optimum pH conditions, each enzyme showed the maximum activity. For example, the optimum pH of an enzyme that works in the acidic environment of the human stomach is lower than that of an enzyme that works in a neutral environment of human blood. All enzymes have an optimum pH that they work best at. Its often neutral pH 7, but not always.

Answer:
It allows the cell to regulate the movement of materials into and out of the cell
Explanation:
This molecule is a saturated fatty acid. The cell membrane is made up of a phosphate head and three fatty acid tails that form a lipid bilayer arrangement.
This lipid bilayer regulates the entry and exit of substances into and out of the cell. Small non-polar molecules, like oxygen and carbon dioxide, are soluble in the lipid bilayer and can easily cross the plasma membrane. Small uncharged polar molecules, like water, can pass through the membrane by osmosis. Larger molecules such as glucose, or charged molecules like ions, require active transport to be passed across the cell membrane.
Answer:
It allows the cell to regulate the movement of materials into and out of the cell

What two parts of a nucleotide do not change throughout the structure of DNA?
Answer:
The second portion of the nucleotide is the sugar. Regardless of the nucleotide, the sugar is always the same. The difference is between DNA and RNA.
Explanation:
thanks me and follow me
Five-carbon sugar (deoxyribose sugar) and phosphate moiety are the two parts of a nucleotide which do not change throughout the structure of DNA.
What are Nucleotides?Nucleotides are the organic molecules which are consisting of a nucleoside molecule and a phosphate moiety. They serve as the monomeric units of the nucleic acid polymers- deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), both of which are the essential biomolecules within all the different life-forms on the Earth.
Nucleosides are made up of nitrogenous bases and pentose sugar. There are changes at the nitrogenous bases in the different nucleoside molecules however, there are no changes in the pentose sugar and the phosphate moiety of the molecule.

It takes place when magma introduces
great amount of heat into an existing rock
resulting in the recrystallization and mineral
reaction in the rock.
Answer:
The correct answer is - contact metamorphism.
Explanation:
Contact metamorphism is one of the two metamorphism processes which takes place when the pre-existing rock is introduced to a great amount of heat which affects it by an intrusion of magma. It is known as a low pressurized, high-temperature type of metamorphism.
An example of this type of metamorphism which experiences recrystallization in the rock and forms a metamorphic marble that is formed by the recrystallization and mineral reaction of the limestone.
PLEASE HELP ME Are humans predators in their ecosystem? Explain in at least 5 sentences.
Their new study shows that humans are strange predators. Unlike other animals, we target adult prey in large numbers. That is a practice that can push populations of those prey into decline, the researchers warn. People mainly target — at least among wild mammals and fishes — prey that are old enough to reproduce.
Humans are considered to be apex predators in their ecosystems due to their ability to manipulate and dominate other species through hunting, agriculture and urbanization.
Why are human predators?Humans are considered to be apex predators in their ecosystem due to their ability to manipulate and change their environment to suit their needs. Humans have the ability to hunt and consume a wide variety of other organisms, including other predators. Humans also have a significant impact on the environment through activities such as deforestation, pollution, and hunting.
However, humans are also capable of acting as stewards of the environment and preserving biodiversity through conservation efforts. The relationship between humans and their ecosystem is complex and multifaceted.

Which statement correctly describes the offspring of asexual reproduction?
Choose 1 answer:
They result without the fusion of gametes.
(Choice B)
B
They vary genetically from the parent.
(Choice C)
C
They contain half of the genetic information of the parent.
(Choice D)
D
They develop very slowly compared to offspring of sexual reproduction.
Answer: the answer is A “They result without the fusion of gametes”
Explanation:
The statement that correctly describes the offsprings of asexual reproduction is: they result without the fusion of gametes.
ASEXUAL REPRODUCTION:Asexual reproduction is a type of reproduction that involves a single parent organism. The single parent cell gives rise to two new daughter cells by undergoing division. As a result, the new organisms are genetically identical to one another, hence, genetic diversity is not ensured. On the other hand, sexual reproduction involves the fusion of gametes to produce genetically different organisms.Learn more about asexual reproduction at: https://brainly.com/question/4100787?referrer=searchResults

Fungus is an organism not drawn in the above food chain although it has a very important role. Describe an important role of organisms such as fungi and bacteria can you help me plz!!!
Answer:
Explanation:
Fungi and bacteria are decomposers. This means they help breakdown dead plant and animal matter.
This is kind of a baseline descripiton but i hope it helps!
Two of the most crucial creatures in an ecosystem are fungi and bacteria. They are essential for the nutrition cycle, the breakdown of organic matter, and the generation of food for other species. In order for other creatures to exploit the complex organic compounds, fungi and bacteria convert them into simpler forms.
What is the way to the food chain ?For instance, when dead plants and animals are broken down by fungi and bacteria, vital nutrients like nitrogen, phosphorous, and sulphur are released into the soil. Following the uptake of these nutrients by plants, food is produced that is then devoured by other species in the food chain.
Additionally, bacteria and fungi collaborate with other living things like plants in symbiotic interactions. For instance, several fungi collaborate with plant roots to provide the providing the plant with nutrients it needs in exchange for carbs.
Mycorrhizal symbiosis is the name for this kind of partnership, which is necessary for the development and well-being of plants. Since many bacteria and fungi produce chemicals that can stop the formation of dangerous infections, they also play a significant part in disease prevention.
Finally, fungus and bacteria are significant food sources for many organisms. For example, fungi like mushrooms and others feed animals like deer, birds, and other fauna.

Cells are a basic unit of life and that without cells you don't exist as a living being. Also, all the other answers have a flaw in them like in question A... not all cells are the same size. For question B and D... not all cells have the same, parts or organelles since for plants they have chloroplast while animals don't.
