Distingush between prokaryotic cell and eukaryotic cell by selecting the accurate statements that apply to eukaryotic cells

Answers

Answer 1

The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. ... Prokaryotes, on the other hand, have no membrane-bound organelles. Another important difference is the DNA structure.

Molecules that make up living things and contain carbon are called __________ molecules.

Answers

Living organisms contain inorganic compounds (mainly water and salts) and organic molecules. Organic molecules contain carbon; inorganic compounds do not. Carbon oxides and carbonates are exceptions; they contain carbon but are considered inorganic because they do not contain hydrogen

Molecules that make up living things and contain carbon are called organic molecules.

Organic molecules are those that derive their three-dimensional configurations primarily from their carbon skeletons.

Organic molecules are essential for the birth, development and functioning of all cells that make up living organisms.

About organic molecules:

All organic molecules contain carbon and practically always hydrogen, it is also frequent that they have oxygen or nitrogen.

These chemical elements enable multiple and covalent bonds to be established, allow carbon atoms to develop three-dimensional skeletons, and give rise to multiple functional groups.

Proteins, vitamins, carbohydrates, lipids, and nucleic acids are organic biomolecules, which are synthesized by living organisms.

Therefore, we can conclude that molecules that make up living things and contain carbon are called organic molecules, which a living being needs to develop normally.

how does increasing the size of the habitat affect carrying? explain your answer. recall the scenarios: 0-15 years, little land; 15-30 tears, moderate land;30-45 years, ample land

plzzz helpp ​
I meant years not tears

Answers

Answer:

so basically carrying capacity is "the amount of organisms a specific environment can support", so if the environment is increased, most likely, more space and food will be available, which means the environment can hold more organisms, causing the carrying capacity to increase

Explanation:

what I just said lol

Answer:

Increasing the habitat size will increase the carrying capacity. Carrying capacity is the maximum amount of organisms a habitat and its resources can carry. So if the habitat expands and more resources become available, the population would expand. As you can see for the first 15 years, when it was the little land, there was only about () rabbits, but as the land grew throughout the years, the rabbit population grew. 15-30 years with moderate land had around () rabbits, and the ample land in years 30-45 had around () rabbits, a little over two times the amount the little land had.

Running for a long period of time, such as during a marathon, can result in muscle fatigue. Which process is important to a runner at the end of a marathon?
A. lactic acid fermentation to produce ATP without oxygen
B. Alchoholic fermentation to release carbon dioxide
C. The Krebs cycle to produce NADH and FADH2
D. The electron transport chain to produce ATP

Answers

The process that is important to a runner at the end of a marathon is lactic acid fermentation to produce ATP without oxygen (Option A).

Cellular respiration refers to the reactions by which aerobic cells normally produce energy in the form of ATP by using energy stored in the chemical bonds of foods and oxygen.

Muscle cells can produce ATP by both cellular respiration (aerobic conditions) and acid lactic fermentation (anaerobic conditions).

Acid lactic fermentation is energetically much less efficient than cellular respiration, but ATP production in cellular respiration is much slower than in fermentation, thereby muscle cells use this pathway (fermentation) when they cannot get oxygen fast enough to meet their energy requirement.

In conclusion, the process that is important to a runner at the end of a marathon is lactic acid fermentation to produce ATP without oxygen (Option A).

As a scientist employed by the FDA, you've been asked to sit on a panel to evaluate a pharmaceutical company's application for approval of a new weight loss drug called Fat Away. The company has submitted a report summarizing the results of their animal and human testing. In the report, it was noted that Fat Away works by affecting the electron transport chain. It decreases the synthesis of ATP by making the mitochondrial membrane permeable to H+, which allows H+ to leak from the intermembrane space to the mitochondrial matrix. This effect leads to weight loss.How would you explain the decreased synthesis of ATP?

Answers

Answer:

The right response is "body temperature".

Explanation:

Whilst also growing the basal leakage of protons, this same drug Fat blocks the development of ATP. The whole change throughout the electrochemical gradient including its proton, therefore, induces the release of a possible form of radiation, rather than being transferred to ATP. Through thermoregulatory autophagy, outlet temperature throughout the individual contributes to loss, associated with elevated body temperature. Elevated body temperature would have the additional effect of removing fat.

Stand and let your hands hang next to your sides for a few minutes. Then, look at the backs of your hands. Do you see any bumps on the surface on top of your veins? What might those be, and what are their function?​

Answers

When you stand and let your hands hang next to your sides for a few minutes, the bumps you see on your veins are the valves that help move blood to the larger veins.

What we know about vein valves.

There are valves located throughout the veins in our bodies. Most of these are located in points where smaller venules fuse with the larger veins.

Their function is to prevent blood from flowing back into the smaller veins, thus helping with the normal blood flow of the body.

Given that the veins in our bodies are littered with small valves to help the blood return to the heart correctly, we can confirm that these are the small bumps that we can see when letting our hands down for a few mins, as they fill with the blood they try not to let flow back into the smaller veins.

Consciousness can best be described as __(blank)__.
a) Internal chemical systems that are regulated by a circadian rhythm
b) an ability to sleep and have lucid dreams
c) a lack of awareness of things going on inside or outside of yourself
d) an awareness of things going on inside or outside of yourself

Answers

d) cause consciousness is when you’re awake and aware

Consciousness can best be described as an awareness of things going on inside or outside of yourself, hence option D is correct.

How consciousness is regulated?

Wakefulness/arousal and awareness are frequently used as the two components that make up consciousness.

It appears that proper arousal levels and subsequently wakefulness, which is required for consciousness, depend on well-synchronized phases of awake and sleep.

Circadian rhythms are changes in the body, brain, and behavior that occur on a 24-hour cycle. Most living things, including animals, plants, and bacteria, are impacted by these natural processes, which predominantly react to light and darkness.

Therefore, the 24-hour cycle of normal physical, emotional, and behavioral changes that the body experiences.

American officials wanted to avoid the problems that caused France to abandon the project. They wanted to protect workers from disease. An engineer, John F. Stevens, was sent to the work camp in Panama. He began building hospitals as well as water and sewage systems making the working conditions sanitary. He supported the camp doctors efforts to fight mosquitoes, the cause of malaria and yellow fever. All of these efforts helped to keep the workers healthy and focused on the task at hand.Using the Panama Canal Since the water level of the Pacific and Atlantic Oceans is not the same, a system of locks and gates had to be built in the canal. These locks are a pathway for ships to move from one ocean to the other. A lock is a giant box made of concrete. A ship must pass through three locks in the Panama Canal. Each lock holds millions of gallons of water. A ship moves into a lock, which is filled with water. Water is pumped into the lock or out of the lock. This raises or lowers the ship to the level of water in the next lock. The gates open, and the ship moves into the next lock. By early 1913, the canal was nearly complete. It took several months to fill the canal with water. On September 26, 1913, an old tugboat was the first ship through the canal. Thousands of people watched and cheered. The locks worked perfectly. In modern times, approximately 14,000 ships make the 50-mile trip through the canal each year. On average, the trip through the canal takes a ship 8 to 10 hours. The ship captain does not steer the ship through the canal. A specially trained canal pilot takes control of the vessel and expertly guides it through the canal. Time, money, and possibly even lives have been saved as ships use the shorter route from ocean to ocean provided by the canal. The Panama Canal, a highway of water, is a phenomenon.
