Answer:

Without the cell membrane, any chemical would be allowed to enter. Membranes are very important because they help protect the cell. Materials move across the membrane by diffusion. Diffusion is the movement of oxygen, nutrients, and other molecules.

Explanation:

Answer: D. the Cell wall

Explanation: The cell wall provides structural support and protection. Pores in the cell wall allow water and nutrients to move into and out of the cell. The cell wall also prevents the plant cell from bursting when water enters the cell.

Also it is also a ridged layer found outside of the cell membrane

from my point of view I think the answer should amino acid can fit into pyruvate oxidation

Carbohydrates can not feed into oxidative phosphorylation, firstly carbohydrates catabolize through glycolysis and the citric acid cycle and release electrons which feed into oxidative phosphorylation.

Acetyl-CoA, a chemical that "feeds" the citric acid cycle, can be produced from pyruvate (a byproduct of glycolysis), fatty acid -oxidation, ketone bodies, and amino acid metabolism.

The citric acid cycle is "cataplerotic" when molecules from other routes enter it for catabolism. Amino acids catalyze the breakdown of pyruvate.

Alanine, serine, glycine (through serine), and cysteine are among the amino acids with three carbon atoms that are transformed into pyruvate (the entry point for the citric acid cycle or gluconeogenesis)

Therefore, carbohydrates can feed into oxidative phosphorylation is false about the catabolic pathway, hence option A is correct.

17. Lipids

18. Carbohydrates

19. Carbohydrates

20. Lipids

21. Lipids

22. Carbohydrates

23. Lipids

Explanation:

Carbohydrates are organic molecules composed of carbon, hydrogen and oxygen. Carbohydrates can be classified into three types: monosaccharides (e.g. glucose), disaccharides (e.g., lactose), and polysaccharides (e.g., starch). Cellulose is a carbohydrate where many glucose rings chain together, while chitin is a polysaccharide consisting of chains of modified glucose molecules.

Lipids represent a diverse group of organic molecules that include, among others, fats, waxes, oils, hormones, etc. Lipids play a role by insulating (and protecting) the body. For example, there is a layer of fats beneath the skin which enables to maintain body temperature relatively constant. In animals, lipids constitute about 50% of the mass of cell membranes. These membrane lipids are mainly phospholipids, glycolipids and cholesterol. There are hormones that derive from lipids such as steroid hormones, which derive from cholesterol. Some examples of steroid hormones are testosterone, estrogen and cortisol.

Answer:

When ATP is converted into ADP + P energy is released and used by the cell.

Explanation: ATP contains energy, when a certain part breaks off it converts into ADP and releases energy for the cell tp use.

When ATP is converted into ADP + Pi , energy is released and used by the cell is the most accurately describes the role of ATP as a source of energy.

An organic substance called adenosine triphosphate (ATP) gives energy to a variety of biological functions in living cells, including muscular contraction, nerve impulse transmission, condensate dissolving, and chemical synthesis.

ATP is frequently referred to as the "molecular unit of currency" of intracellular energy transfer and is present in all known forms of life. It either transforms into adenosine monophosphate (AMP) or adenosine diphosphate (ADP) when absorbed in metabolic activities (AMP).

ATP is replenished by other processes. Every day, the human body recycles the equivalent amount of ATP to its own body weight. Additionally, it serves as a coenzyme and a precursor to DNA and RNA.

Therefore, When ATP is converted into ADP + Pi , energy is released and used by the cell is the most accurately describes the role of ATP as a source of energy.

Explanation:

Answer:

( A. joints between long bones )

Answer: joints between long bones

Explanation:

Every single cell of an organism is able to survive independently because it carries out metabolic processes at its own.

Metabolism can be defined as the chemical changes or reactions which take place in a cell or an organism. These changes make energy and the compounds which cells and organisms need to grow, reproduce, and stay healthy.

Metabolism is divided into two classes: anabolism and catabolism.  Anabolism involves the synthesis of a complex compound from simpler or smaller molecules or atoms. Catabolism involves the breakdown of a complex molecule into smaller and simpler ones.

Living organisms are able to perform the metabolic processes such as respiration, excretion, reproduction, and digestion which is a distinguishing factor from that of non-living organisms.

Answer:

B. The number of trophic levels is limited, and typically is less than 10.

C. On average, about 10 percent of available energy is transferred from one trophic level to the next.

D. Among consumers in an ecosystem, first-level consumers have the most available energy

Explanation:

The number of trophic levels are limited. when one available energy is transferred from one trophic level to another trophic level, about 10 percent of energy is transferred whereas the rest of the energy about 90 percent is released in the form of heat energy. The first-level consumers have the most available energy due to higher biomass.

Answer:

The amount of caffeine that would be consumed if one eats the entire king-size bar will be 11.99 mg

Explanation:

This question can be reframed in the manner below for better understanding.

If 1.5 oz or ounce of a chocolate bar contains 6 mg of caffeine, how many milligrams (mg) of caffeine is contained in 85 grams of the same chocolate bar.

Firstly, the ounce should be converted to grams

If 1 ounce = 28.35g

1.5 ounce = ?

= 1.5 × 28.35/1

=42.53g

Hence, 42.53g of the chocolate bar contains 6 mg of caffeine

85g of the chocolate will contain

42.53g = 6mg

85g = X

where X is the amount of caffeine that will be consumed in mg

X = 85 × 6/42.53

X = 11.99 mg

The amount of caffeine that would be consumed if one eats the entire king-size bar will be 11.99 mg

Answer:

The craters on what? Is there supposed to be a picture added to this?

Explanation:

Answer:

This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed: Example:  For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.

This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side: Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.

This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such: Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.

Genes help to define who an individual is inside and out. In addition to visible traits like weight and eye color, psychological qualities such as personality traits, intelligence, risk of mental illness, and more have been linked to genetics.

Explanation:

Tides occur when the Earth, the Sun, and the Moon are in a line. The gravitational forces of the Moon and the Sun both contribute to the tides. Spring tides occur during the full moon and the new moon.

The event that causes tides is the interaction of the moon, the Sun, and Earth.

The sea level can be affected by the interaction of the moon, the Sun, and Earth in a process called tides

Tides can be defined as the waves that moves through the ocean or sea, causing a rise or a fall in the levels of the sea as an interaction of the sun and the moon.
