Food storage and digestion take place in an amoeba occur through food vacuoles.

Amoeba is a monocellular organism that shows holozoic nutrition. It absorbs nutrients and food from the surroundings by contracting the vacuole. It has pseudopodia a drizzle-like structure that moves food into the vacuole. Inside this vacuole, there are lysosomes that contain the hydrolytic enzymes. These enzymes perform the breakdown of food particles. The digested food is then directly absorbed through the cytoplasm. This is circulated to organelles and stored for energy. After assimilation, the undigested food and waste are excreted out by fusing of food vacuole with the cell membrane.

Answer:

Explanation:Amoebas are single-celled organisms that belong to group protozoa.Food storage and digestion occur through process called phagocytosis. Due the presence of flexible membrane,they can change their shape,viz essential for their feeding mechanism.

Psuedopods are temporary projections of its cell membrane which is extended when it encounters a food particle. These pseudopods surround the food particle forming a small cavity called food vacoule.

Once the food particle is enclosed within the food vacuole, the membrane of the vacuole fuses and forms a (digestive vacuole)phagosome which contains the food particle and digestive enzymes. The digestive enzymes in phagosome breakdown the food particle into smaller molecules. The enzymes include proteases for protein digestion, carbohydrases for carbohydrate digestion, and lipases for lipid digestion.

Smaller molecules are gradually absorbed into the cytoplasm of the amoeba, where they can be utilized for various metabolic processes. The digestion products are transported across the membrane of the digestive vacuole into the cytoplasm through diffusion.

Any undigested or indigestible material is eventually expelled from the amoeba's body by process of exocytosis. During exocytosis, the residual waste material is packaged into a vesicle and then released outside the cell.

Food storage and digestion in amoebas involve

1: the engulfment of food particles through phagocytosis,

2: the formation of digestive vacuoles,

3: enzymatic breakdown of the food,

4:absorption of nutrients into the cytoplasm,

5: and elimination of waste materials through exocytosis.

True, the highest rate of oxygen consumption an individual is capable of during maximum physical effort, reflecting the body's ability to transport and use oxygen, is a person's maximal oxygen consumption (VO2max).

Maximal oxygen consumption (VO2max) is the highest rate of oxygen consumption an individual is capable of during maximum physical effort, reflecting the body's ability to transport and use oxygen. It is considered a key measure of cardiovascular fitness and endurance. During exercise, oxygen is necessary for energy production, and VO2max reflects the body's ability to deliver oxygen to the working muscles.

Explanation:

Triglycerides are a type of fat that is typically found in animal-based foods such as butter, cream, and fatty meats, as well as coconut and palm oil. They are solid at room temperature and are known to raise the levels of LDL cholesterol in the blood which can increase the risk of heart disease.

I hope this helps :)

Answer:

I think its c

I am sorry if my answer is wrong

Explanation:

Saturated fats found in animal products, such as bacon and cheese, are also called long-chain fatty acids. These fats are typically solid at room temperature and are known to increase the levels of LDL cholesterol in the blood, which can increase the risk of heart disease if consumed in excess. Saturated fats are also found in some plant-based oils, such as coconut oil and palm oil, and in processed foods like baked goods and fried foods.

Lipids are a broad group of naturally occurring molecules that include fats, waxes, steroids, and certain fat-soluble vitamins. Lipids are important components of living cells, and they play a variety of roles in the body, including energy storage, insulation, and cell membrane structure.

Fats, also known as triglycerides, are the most common type of lipid. They are composed of three fatty acid molecules and one glycerol molecule. Saturated fats, which are typically solid at room temperature, are known to increase the levels of LDL cholesterol in the blood, which can increase the risk of heart disease if consumed in excess. Unsaturated fats, which are typically liquid at room temperature, are considered to be healthier.

Waxes are lipids that are composed of long chain fatty acids and alcohols. They are used in various products such as candles, cosmetics, and food packaging.

Steroids are lipids that are composed of four fused carbon rings. They are important hormones in the body such as testosterone and estrogen.

Lipid-soluble vitamins such as vitamin A, D, E, and K are required in small amounts for good health and are stored in the body's fatty tissue.

In summary, lipids are a diverse group of molecules that play important roles in the body, including energy storage, insulation, and cell membrane structure. They include fats, waxes, steroids, and some fat-soluble vitamins, and their properties and functions vary depending on their chemical structure.

The three correct statements are as follows:

a. The population that existed before mining must have included both copper-tolerant and copper-intolerant plants.

c. Natural selection favors copper tolerance in all soils near the old mine, not only in the contaminated soils.

d. Copper contamination in the soil created copper-tolerant plants.

a. This statement is true because the presence of copper-tolerant plants indicates that there must have been genetic variation in the population before mining occurred. If all the plants were copper-intolerant, there would be no basis for natural selection to favor copper tolerance.

c. This statement is true because natural selection operates based on the fitness of individuals within a population. If copper tolerance provides a selective advantage in any soil, including those near the old mine that may not be contaminated.

d. This statement is true because exposure to copper contamination in the soil can lead to the selection and survival of individuals with genetic traits that confer copper tolerance.

The specialization of cells in multicellular organisms plays a vital role in maintaining homeostasis. Homeostasis refers to the stable internal environment required for optimal functioning of an organism.

Specialized cells have specific functions and structures that allow them to carry out specific tasks. This division of labor allows different cell types to perform specific functions, such as nutrient absorption, waste removal, hormone secretion, and nerve transmission. By focusing on specific tasks, cells can efficiently contribute to the overall functioning of the organism.

Specialization also enables cells to interact and communicate with each other. Cells can coordinate their activities through signaling pathways, allowing for coordinated responses to changes in the internal and external environment. This intercellular communication helps maintain balance and adjust physiological processes to maintain homeostasis.

In summary, cell specialization ensures that each cell type can perform its designated role, contributing to the overall functioning and stability of the organism's internal environment, thereby supporting homeostasis.

Petroleum-derived combination of flammable, volatile liquid hydrocarbons used as fuel for internal combustion engines; often spelled gasolene, gas, or petrol.

Additionally, it serves as a fat and oil solvent. Because of its high energy of combustion and ability to mix easily with air in a carburetor, gasoline—originally a byproduct of the petroleum industry, with kerosene being the main product—became the favored fuel for automobiles.

Not specifically to combat lead poisoning but because lead was known to interfere with new smog-reducing catalytic converters that from 1975 would be built into new cars.
