Answer:

carbon dioxide is what the plants take from the air to make glucose or sugar

The molecules that the plants pull from the air that is used to make sugar are carbon dioxide. The correct option is D.

Carbon dioxide is a gas that is present in the atmosphere at 0.03 %. This gas is a greenhouse gas. This gas warms the environment. The chemical formula of carbon dioxide is CO₂.

Carbon dioxide is released by animals as they respire. This is the gas they expelled out in respiration. But plants absorb this gas because plants perform photosynthesis and in photosynthesis, carbon dioxide is used.

This gas is pulled from the environment to perform photosynthesis by plants. Carbon dioxide reacts with water to form glucose.

The chemical reaction of photosynthesis

\(\rm CO_2 + 6H_2O \rightarrow C_6H_1_2O_6 + 6O_2.\)

Thus, the correct option is D. Carbon dioxide.

Particulate matter (PM) refers to tiny particles suspended in the air that can have harmful effects on human health and the environment. Sources of particulate matter in the air include automobiles, dust, and fires.

Automobiles emit exhaust emissions that contain particulate matter, especially from diesel engines. Dust particles can be generated from various sources such as construction sites, unpaved roads, and agricultural activities.

Fires, including both wildfires and controlled burns, release smoke and ash particles into the air. These particles can vary in size and composition.

All of these sources contribute to the presence of particulate matter in the atmosphere, and their emissions can have detrimental effects on air quality and public health if not properly managed or controlled.

Therefore option D all of the above is correct.

No, sucrase will not catalyze the breakdown of the disaccharide maltose. This is because sucrase is specifically designed to break down sucrose, which is a different disaccharide made up of glucose and fructose molecules.

Maltose, on the other hand, is made up of two glucose molecules and therefore requires a different enzyme called maltase to catalyze its breakdown. Enzymes are highly specific in the reactions they catalyze, and this specificity is determined by the shape and structure of the active site of the enzyme. While sucrase and maltase may have similar structures, their active sites are not identical, and therefore they cannot catalyze the same reactions.

Overall, the breakdown of complex carbohydrates into simpler sugars is a complex process that requires the action of multiple enzymes, each with its own specific function and target substrate.

Answer:

Whats going on is that you have a specific amount of enzyme that can do a specific amount of work. Think of it like a hotdog stand. the enzyme would be you and your substrats are your hot dogs and buns. You can only go as fast as the materials you have. If you have more materials than hands you can only go as fast as you can make them. To many substrates and you enzyme rate will cap out at maximum speed.

Explanation:

The plot shows rate of reaction of an enzyme as a function of the concentration of substrate. At stage B, the rate flattens and becomes constant, which means there's too much substrate for the enzyme to handle. So the fourth statement is false - the rate of reaction cannot be increasing.

Answer and explanation:

An ecosystem that is highly resilient is one that has the capacity to resist subjected damage by maintaining its normal patterns of biomass production and the cycling of nutrients. This damage can be anything from fires to deforestation.

A highly resilient ecosystem can be expected to adapt well to change, sometimes permanently, to survive indefinitely. For an ecosystem to be resilient, it has to be flexible and be able to adjust to uncertainty. Highly resilient ecosystems tend to have reproductive cycles, trophic cascades, and population connectivity - all of these characteristics give these ecosystems better chances of surviving different types of disturbances.

Random mutation is not an mechanism of evolution .

Five important factors for evolution mechanism are Natural Selection, genetic drift, gene flow, mutations, and non random mating. Through these process members of a population differs greatly in their traits.

Natural selection is the most important mechanism of evolution, other evolutionary mechanisms can also change the frequencies of traits in populations. These include mutation, genetic drift and migration. Natural selection have 5 basic and major components These are Variation (individual have variation in appearance and behavior ), Inheritance( traits are continuously passed on from parent to offspring), Selection, Time and Adaptation.

The cluster of brain cells that control the circadian rhythm is the suprachiasmatic nucleus.

The suprachiasmatic nucleus (SCN) is a tiny cluster of brain cells in the hypothalamus area of the brain. The SCN controls the circadian rhythm, which is the body's natural biological cycle. It determines when people sleep, wake up, and perform specific functions throughout the day. Circadian rhythms may also influence human behavior and physiology.

For example, the circadian rhythm affects the body temperature, hormone secretion, and immune system function. These rhythms can alter and make the body more susceptible to sleep disorders, depression, and other health problems.

The inner membrane of the mitochondria does provide a large surface area for breaking down the bonds in sugar molecules.

Mitochondria are organelles found in the cells of eukaryotic organisms, including animals, plants, and fungi. They are often referred to as the "powerhouses" of the cell because they are responsible for producing the majority of the cell's energy supply. Mitochondria have a double membrane structure, with an outer membrane and an inner membrane. The inner membrane is folded into small, finger-like projections called cristae, which increases the surface area of the membrane.

Mitochondria are the site of cellular respiration, a process by which energy is extracted from organic molecules, such as glucose, to produce the energy-rich molecule adenosine triphosphate (ATP). The energy released from this process is used by the cell to perform various functions, such as muscle contraction and protein synthesis.

Mitochondria also have their own DNA and reproduce independently of the cell. They are thought to have originated as a symbiotic relationship between ancient cells and bacteria. They have their own genetic material, which suggests that they have a separate evolutionary history from the rest of the cell.

Epithelial tissue which is found lining the kidney glomerulus, and performs blood filtration is simple squamous epithelium

The mediators of filtration and diffusion are Simple squamous epithelial cells. Because of their simple and thin design, they facilitate the transmembrane transit of small molecules (i.e., over the membrane and through the cell).

Certain chemicals, like as oxygen and carbon dioxide, move easily through the simple squamous epithelia in accordance with concentration gradients. Since other molecules, including ions, use transmembrane protein channels to diffuse across the cells, the types of proteins present in a particular simple squamous epithelial tissue partially define the function of that tissue.

What can flow from the lumen and into the circulation, and vice versa, is governed by the simple squamous epithelia since the capillary bed is situated underneath the basement membrane.

no. Due to iodine deficiency, even if you stimulated the thyroid gland with TSH, you will not identify an increase in T3 and T4 synthesis in these individuals.

Thyroxine (T4) and triiodothyronine, two thyroid hormones, are produced by the thyroid gland from iodine, which is present in a variety of diets (T3). In the body, iodine can only be absorbed by thyroid cells. To produce T3 and T4, these cells mix the elements iodine and tyrosine. Iodine is a key necessary mineral without which the thyroid cannot produce enough amounts of T4 and T3.
