No, the asteroid belt is not able to unite into a 9th planet because there is not enough total mass in the belt to form a planet. the other reason is that the belt is too close to Jupiter which make impossible to make the asteroid belt a planet. When this formation of new planet happens between the asteroid and Jupiter, Jupiter's gravitational forces act on the asteroid add up and strengthen each other, and they can easily kick the asteroid out of the solar system.

What best describes the interaction described below:
Grass and Dandelions- Both plants try to get nutrients and water from the same area
of soil

O parasitism
O Competition
O Predation
O Commensalism
O Mutualism

Answers

Answer:

Mutualism

Explanation:

Both plants don't fight over the spot and are in within the same place.

Grass and Dandelions both compete for nutrients and water belongs to the same species, competition occurs between the same species called interspecific competition, hence option b is correct.

What is the interaction between Grass and Dandelions?

When two distinct species fight for a restricted resource, such as space, this is known as interspecific competition. Grass, dandelions, and a variety of other plants compete for nutrients and water on a lawn.

Competition happens among individuals of the same species as well.  The deep taproot draws minerals from the earth, such as calcium, and makes them available to other plants. While most think of dandelions as lawn killers, they really enrich the grass.

It will attach itself to sharks and other large fish in order to get a ride underwater. This is an example of commensalism but this connection can evolve into mutualism when the remora feeds.

Therefore belongs to the same species kind of interspecific relation, Grass and Dandelions having the interaction of competition, hence option b is correct.

How might retaining too much heat be a disadvantage to an organism?

Answers

Answer:

Too much heat can disrupt subcellular structures such as membrane proteins, and enzymes while damaging the integrity of the plasma membrane.

Explanation:

Proteins are macromolecules made up of amino acids. These fold and bond to form several biologically important molecules. For instance, enzymes, a special type of protein functions by providing alternative reaction pathways. They work best at a specific pH and optimal temperature range, beyond which they become non-functional  or denatured entirely.

The denaturing of proteins occur at high temperatures, and alter protein folding, bonding and other types of behavior. Furthermore, membrane proteins are  important for regulating cell function. If these are disrupted, the system cannot maintain homeostasis i.e a constant internal environment.

Explanation:

Photosynthesis, occurs in the chloroplasts of plants. Here, solar  energy is converted into chemical energy in the form of stable carbohydrates.

             6 CO2 + 6 H2O + light  →  C6H12O6 + 6 O2

Carbon Dioxide + Water + Light       Glucose + Oxygen

Chloroplasts, are small membrane-bound organelles of multi-folded membranes containing pigments, enzymes, and other molecules that facilitate the process.

Nutrients for a number of metabolic processes are basic compounds and macromolecules available. Through processing organic matter such as lipids, fats and proteins, animals get energy in heterotrophic nutrition.

For one for all metabolic processes, animals use carbohydrates as food. This occurs in the mitochondria...
