Why
will some molecules such as oxygen, carbon dioxide, nitrogen freely
move through the lipid bilayer of the cell membrane? *
O They are hydrophobic.
O They are ions.
O They are small, non-polar.
They are polar​

Answers

Answer 1

Answer:

Explanation:

Option A they are hydrophobic is the correct answer

Answer 2

These molecules move across the lipid membrane because they are hydrophobic. So the correct option is A.

What is hydrophobic?

In both the home and industrial realms, several hydrophobic materials may be discovered. The vast majority of organic molecules, alkanes, oils, fats, and greasy substances are hydrophobic by nature.

Hydrophobic chemicals are used in a variety of processes, such as the chemical separation of polar elements from non-polar ones, the cleanup of oil spills, and the removal of oil from aqueous solutions. It is a well-known fact that when oil or fats are combined with water, two different layers are created that are inimical to one another since water is polar, but fats and grease are non-polar and especially hydrophobic.

Animals and plants both exhibit hydrophobicity as examples. There are hydrophobic coats on the surface of the leaves since many plants are hydrophobic in nature. The coating's main duty is to prevent water and rain from adhering to the leaves, which often stops the flow of nutrients.

The movement of water from roots to leaves determines how quickly nitrites move through plants. Therefore, if the leaf surfaces lack hydrophobicity, the osmosis process and osmotic pressure will be disrupted, which will have a significant impact on how well plants are nourished.

Therefore the correct option is A.

Answers

The options are;

A) biology; theory of relativity

B) geology; theory of continental drift

C) ecology; discovering new elements

D) astronomy; developing quantum mechanics

Answer:

B) geology; theory of continental drift

Explanation:

Looking at the options;

-theory of relativity is a topic in physics originated by Einstein. Thus, it is matched to physics and not biology.

- theory of continental drifts are related to plate tectonics where it explains how continents shift position on Earth's surface. This is a branch of Geography and is thus correctly matched.

- discovering new elements is a topic under chemistry and not ecology. Thus, this is not matched correctly.

-developing quantum mechanics is a topic in physics that deals with the relationship between energy and matterwith respect to atomic and subatomic scale. Thus, it is not well matched.

As Earth moves along its orbit, its shadow falls on different parts of the Moon

Answers

Answer:As the Moon moves along its orbit, only a fraction of it is visible from Earth

Explanation:

The different portions of the Moon are visible at different times of the month as as the Moon moves along its orbit, only a fraction of it is visible from Earth.

What is moon orbit ?

The moon travels across the Earth in an elliptical orbit, a barely stretched-out circle. When the moon is closest to Earth, its rotation is slower than its adventure via space, permitting observers to look an extra eight tiers at the jap side.

Different quantities of the moon are seen at special instances of the month due to the location of the moon in its orbital path. From Earth, we're in reality viewing the sun's rays being pondered off diverse quantities of the moon's floor all through its orbit.

Answers

Answer:

Because oxygen is circulated throughout the body via the bloodstream, there is a strong connection between the cardiovascular system and the respiratory system.

Explanation:

The cardiovascular system is responsible for the transport of oxygen to all tissues of the body, in addition to the removal of carbon dioxide, which depends on the close interaction with the respiratory system.

A summary of the strong connection between the cardiovascular and respiratory systems is :

Blood contains red blood cells, which are responsible for transporting O₂ and CO₂ by binding to the hemoglobin molecule, present in these structures. The respiratory system is responsible for providing air with O₂ and removing CO₂, a process that depends on gas exchange at the level of the pulmonary alveolus.

The illustration shows one of the ways resources are removed from the deep sea. Describe what type of resources these are, including if they are renewable or non-renewable. Predict two consequences to the seafloor life if this process is not regulated.

Answers

Answer:

Marine mining is a process that can be done by dredging the seabed and is used for the extraction of mineral resources from the seabed, which are non-renewable, with a negative impact on marine ecosystems.

Explanation:

The illustration shows a process of marine mining by dredging, where the resource extracted is of a mineral nature, like copper, zinc, silver and gold. Gravel used for construction can also be extracted from the sea. Mineral resources extracted from the sea are not renewable.

The process of marine mining can be harmful to the ecosystems there, so it must be a process that requires control and management from the ecological point of view.

Two possible consequences of not regulating marine mining are:

Destruction of the habitat of life forms present on the sea floor, which endangers many species and even forces migration to more stable areas, with consequences on the food chains.Extinction of marine species that inhabit the seabed. The flora and fauna of the sea floor usually have slow reproductive cycles and, in the case of fish, spawning takes place on the bottom of the sea. Mining endangers the reproductive cycles of the species, leading to induced extinction.

Responsible and controlled mining activity can be useful for humans, while avoiding negative consequences on the ecosystems that exist at the seabed.

Why do fishes die when they are taken out?​

Answers

Cuz for humans we need oxygen to breathe, for fish the way they breathe is water, if humans don’t have oxygen we die, if fish don’t have water they die.

Answer:

Fishes take oxygen through their gills. Gills are richly supplied with blood capillaries and can readily absorb oxygen dissolved in water. Gills of fishes are not equipped to take in gaseous oxygen (oxygen from air). Hence, a fish when taken out of water is unable to inhale oxygen rich air and so, dies quickly.

What are the advantages and disadvantages of anaerobic fermentation?

Answers

Answer:

- Advantages: doesn't need oxygen, it is faster than aerobic metabolism

- Disadvantages: less energy is produced for every molecule broken down

Explanation:

Anaerobic fermentation (also known as acid lactic fermentation) is a group of O2-independent metabolic reactions where glucose and other sugars are converted into energy (especially ATP, the energy currency of the cell) and lactic acid. This metabolic pathway occurs in types of bacteria and specific animal cells (for example, muscle cells). In contrast to aerobic respiration, the amount of energy produced by the anaerobic pathway is much smaller because it does not involve ATP production by the Krebs cycle or electron transport chain (the aerobic pathway generates up to 38 ATP molecules per glucose, while the anaerobic pathway produces only 2 ATP molecules per glucose). Moreover, anaerobic fermentation produces lactic acid that may be absorbed by the liver (too much lactic acid may have harmful effects). Finally, it is also important to note that the anaerobic pathway is faster than aerobic metabolism.

True

Explanation:

Cofactor is a biological term used in describing a form of a non-protein chemical compound. It is highly required in the biological operation. It is in two types, the Coenzymes and Prosthetic groups.

While the Prosthetic groups are well connected to an enzyme, the coenzymes on the other hand are conected to an enzyme loosely.

Hence, it is TRUE that Cofactors for some enzymes are not considered prosthetic groups because they are loosely held during the course of the action

The cafeteria menu will also be changed to eliminate junk food. I believe this is an unnecessary and costly decision that limits students options and rights. (2) Those in favor of the proposal are motivated by health concerns, specifically high levels of obesity among students. It may be true that obesity is a serious problem, but banning foods is not the right way to address it. For example, a United States Department of Agriculture study points out that students get less than one third of their daily calories at school. They eat most of their food at home, where the ban does not apply. So it is unlikely the boards action alone will reduce obesity. (3) Learning to make good choices and taking responsibility for our actions is an important part of education. The Hillside School Handbook says that on page 23. In keeping with that ideal, we should teach students more about nutrition so that they choose healthier meals. An across-the-board ban on certain foods suggests that students cant make responsible decisions. The ban weakens personal responsibility. (4) How do you define junk food? Are cheeseburgers, chicken nuggets, and pizza really junk? They are if you read the fine print in the school boards plan. According to the cafeteria staff, however, they notice these meals are far more popular among students than other entrees. If the school board plans to replace these meals with brown rice, carrot sticks, and raisins, no one will want to buy the meals. (5) The boards decision has financial implications too. According to last years school budget, Hillside received over $15,000 from the owners of the vending machines. That money went directly toward the schools academic program.
