Answer:

c

Explanation:

the question is asking about the energies. when the two cars are moving towards each other they are accelerating meaning they have kinetic energy. when they collide; on rebounding, the car regains a smaller amount of kinetic energy – this time travelling backwards. So the overall process is that kinetic energy becomes heat and spring potential energy, which results in heat, smaller kinetic energy and, hopefully, surviving occupants. so the speed of the car before and after will show the energy change

Which is a disadvantage of using aquaculture to produce fish?
Advocard [28]

Answer:

Aquaculture is a type of farming performed in water bodies like lakes, ponds, oceans to breed aquatic plants and animals like fish, mollusks, crustaceans, algae, etc. Aquafarming is done to increase food production and to earn money from it.

Apart from the advantages aqua farming has several disadvantages. One of the main disadvantages is the transfer of parasites or diseases from one fish to another is easy in aquaculture because fishes live in dense populations in aquaculture. So fish in aquaculture are highly vulnerable to diseases.

Excess fecal matter produced by farmed fish can pollute the ecosystem which has an adverse effect on the other species live in that ecosystem.

When a potassium ion (K) moves from the soil into the vacuole of a cell on the surface of a root, it must pass through several c
Sindrei [870]

Answer:

C) primary cell wall --> plasma membrane --> cytoplasm --> tonoplast

Explanation:

When a potassium ion moves from the ground into a vacuole of a plant cell, it must pass through the different structures that are part of it.

First, the outermost layer of the cell is the cell wall. Plant cells may have a primary and a secondary wall, but the latter is not always present. The primary wall is always located outwards (and in the case of having a secondary wall, it will be located between the primary wall and the plasma membrane).

Then, inside the cell wall, we will find the plasma membrane (also called plasmalemma).

When crossing the membrane, the ion will be in the cytoplasm of the cell and will be directed towards the vacuole, which is surrounded by its membrane called tonoplast. The vacuole is an organelle that has no definite shape, although it is always surrounded by the tonoplast, and it contains different substances such as water and enzymes.

Explanation:

The biotic factors of an ecosystem include all the populations in a habitat, such as all the species of plants, animals, and fungi, as well as all the micro-organisms. Also recall that the nonliving factors are called abiotic factors. Abiotic factors include temperature, water, soil, and air.
