Fish and larval amphibians live in water. Although their cells produce all three forms - ammonia, urea, and uric acid - the major form of nitrogenous waste that these animals actually excrete in their urine is which, and why

Answers

Answer 1
Answer:

Ammonia

Explanation:

The major form of nitrogenous waste that fish and larval amphibians actually excrete is ammonia because it is easily excreted in water

An ammonotelic organism excretes nitrogenous waste as soluble ammonia

Most of the aquatic animals including protozoans, crustaceans, platyhelminths, cnidarians, poriferans, echinoderms, fishes, larvae / tadpoles of amphibians are ammonotelic

The majority of ammonia produced by typical fish species results from amino acid catabolism via specific deaminases or by transdeamination through the combined actions of aminotransferases and glutamate dehydrogenase (GDH) where transdeamination is generally considered to be the major route of ammonia production

Bears and coyotes both consume large plant-eating mammals such as deer. When the deer are in short supply, bears andcoyotes may fight over the prey. This type of biological interaction is called a. Commensalism c. mutualism b. Competition d. rumination

Answers

The answer is competition.


Competition is an interaction between members of the same species or between different species. If resources, such as food, water, sunlight, territory, are limited and several species depend on these resources, then, they must compete with other species to gain the resources. In this example, bears and coyotes depend on deer and when deer population is reduced, bears and coyotes must compete in order to survive.

Answer:

Its competition

Explanation:

Bears and coyotes will fight over the deer if the deer are in short supply so they won't have much deer to consume

What draws water back to earth?

Answers

Answer with Explanation:

Wateris a very essential substance on earth. We need it for everyday living. When we talk about the "water cycle," it starts with evaporation. This is the process of converting water from liquid to gas form, which is aided by temperature. This allows the water vapor to go to the atmosphere.

Once water vapor is in the atmosphere, it goes back to earth in the process called "precipitation." This process happens when the water vapor condenses and then once it becomes heavy, it falls back to earth through "gravity."

The atmosphere needs a sufficient amount of water vapor in order for it to be saturated. This aids in condensation, which cools down the water vapor and turns it into droplets, also known as "ice crystals." When the number of droplets becomes large enough by grouping together, they form the clouds. When they get even bigger, they fall from the sky as rain, drizzle, hail, snow , etc. through the earth's force called gravity. This process is what you call precipitation.

This is what draws water back to the earth.

Final answer:

Gravity is the force that pulls water back to Earth. This is observable in phenomena like rain and the water cycle. The force of gravity draws evaporated water back down to the Earth, completing the water cycle.

Explanation:

The force that draws water back to the earth is known as gravity. Gravity is a natural phenomenon by which all things with mass or energy are brought toward one another. On Earth, gravity gives weight to physical objects and causes the ocean tides.

When you see water falling from a faucet or a raindrop falling to the ground, the force of gravity is pulling it down towards the earth. Similarly, the process of evaporation separates water from the Earth's surface, and it rises into the atmosphere. When it cools and condenses, it forms clouds and when the clouds become too heavy, gravity pulls the water back down in the form of rain, completing the water cycle.

Explain in your own words how the Cell Theory is an example of a scientific theory.

Answers

Explanation:

Cell theory is the historic scientific theory, now universally accepted, that living organisms are made up of cells, that they are the basic structural/organizational unit of all organisms, and that all cells come from pre-existing cells. Cells are the basic unit of structure in all organisms and also the basic unit of reproduction.

Which of the following is LEAST likely to be important in holding the components of a biological membrane together? hydrophobic interactions between the phospholipid tails and the surface of intergral membrane proteins buried in the membrane polar interactions among the phospholipid head groups on the same surface of the membrane hydrophobic interactions among the fatty acid tails of phospholipids on opposite sides of the membranes covalent interactions between the phospholipid and protein components of the membrane hydrophobic interactions among the fatty acid tails of phospholipids on the same side of the membrane

Answers

The component that is LEAST likely to be important in holding the components of a biological membrane together is C: "covalent interactions between the phospholipid and protein components of the membrane".

The biological membrane is made up of a lipid bilayer, with the hydrophobic tails of the phospholipids facing inward and the hydrophilic heads facing outward. The main forces that hold the membrane together are hydrophobic interactions between the phospholipid tails and the surface of integral membrane proteins buried in the membrane, polar interactions among the phospholipid head groups on the same surface of the membrane, and hydrophobic interactions among the fatty acid tails of phospholipids on opposite sides of the membrane.

Covalent interactions between the phospholipid and protein components of the membrane are not typically important in holding the membrane together. These interactions are much stronger than the other types of interactions and are not typically found in biological membranes. Instead, the membrane components are held together by weaker, non-covalent interactions that allow for the fluidity and flexibility that is necessary for the membrane to function properly.
