Answer:

Movement occurs from higher concentration to lower concentration.

Explanation:

Strip A cell has 30% of sugar which is placed in a solution of 10% sugar so the sugar that is present in the potato strip A moves from inside to the outside due to the process of osmosis while on the other hand, if strip B was placed in 50% of sugar solution so the sugar moves inside from outside environment through semi-permeable membrane. This movement occurs due to difference in concentration of both environments i.e. cell and solution.

Two equal strips A and B were from a potato whose cell was 30% of sugar. strip A was placed in a solution of 10% sugar concentration while B was placed in 50%  sugar concentration

a) strip become flaccid and strip B will swell

b) hypotonic solution causes movement of water to diffuse out of cell

Salts and sugars in solution will diffuse away from areas of high concentration into the surrounding solution

Thus, Two equal strips A and B were from a potato whose cell was 30% of sugar. strip A was placed in a solution of 10% sugar concentration while B was placed in 50%  sugar concentration

a) strip become flaccid and strip B will swell

b) hypotonic solution causes movement of water to diffuse out of cell

Sorry if I'm wrong but I think it's B

Explanation:

A population bottleneck or genetic bottleneck is a sharp reduction in the size of a population due to environmental events such as famines, earthquakes, floods, fires, disease, and droughts or human activities such as specicide and human population planning.

Answer:

A mutualistic relationship is formed when an Alcon blue caterpillar lives in a Myrmica ant nest. Thus, the correct option is B.

A mutualistic relationship is an interaction when two organisms of different species work together in such a way that each species is benefiting from the relationship.

The Caterpillars of the alcon blue butterfly have developed an outer coat on their body that tricks the Myrmica ants into believing that the young are its own, this results into duping the ants to carry the larvae back to their colonies to care for. Once in the nest, the caterpillar becomes a parasite. The Myrmica ants will feed the adopted larvae in preference to their own, and the ant colony will produce fewer offspring in the nest.

Therefore, the correct option is B.

Explanation:

Answer:

The fish would grow in the population, because osprey mainly eat fish.

Because of the fish growth, the ocean, pond, or whatever, makes the water have less oxygen. The fish eat small fish, crustaceans, worms and almost anything that is not poisonous to them. These populations will decrease.

Because there are no Ospreys, the raccoons will get hungry too, as they sometimes eat Osprey eggs.

Answer:

False.

Explanation:

A solvent is the substance that does the dissolving – it dissolves the solute. In salt solution, water is the solvent. During dissolving, particles of solvent collide with particles of solute. They surround the particles of solute, gradually moving them away until the particles are evenly spread through the solvent.

The molecules are still there.

Answer:

Phenotype ration of Green : other color plant will be 3:1

Genotype ration would be GG:Gg:gg

1:2:1

Explanation:

Let the dominant allele for green color of plant be G

Recessive allele for the above allele pair would be g let us say that "g" imparts black color

Then the genotype of two heterozygous green plants would be "Gg"

Gg * Gg

GG, Gg, Gg, gg

The three individuals of genotype GG, Gg, Gg will have green color

while the gg individual will have black color (as assumed)

Phenotype ration of Green : other color plant will be 3:1

Genotype ration would be GG:Gg:gg

1:2:1

On more technical scrutiny; Mushrooms (Agaricus bisporus) belong to the fungi family- they are fungi. Mushrooms are classed as Basidiomycetes and conveniently given their own order: Agaricales.

Answer:

Mushrooms are fungi. They belong in a kingdom of their own, separate from plants and animals. Fungi differ from plants and animals in the way they obtain their nutrients

"Manganese is a grey-white, hard and very brittle metal.

It tarnished on exposure to air and oxidized to manganese when heated."

Credits to: Yahoo

Answer:

Manganese is a pinkish-gray, chemically active element. It is a hard metal and is very brittle. It is hard to melt, but easily oxidized. Manganese is reactive when pure, and as a powder it will burn in oxygen, it reacts with water (it rusts like iron) and dissolves in dilute acids.

Explanation:

There are several key reasons for high biodervisity in tropical ecosystems. High NPP directly contributes to a diversity by supporting more species with minimum viable populations of each organism increase overall mutation frequency and hence intraspecific genetic varation.

Answer:

variation in a population exists

Explanation:

Variation is present in a population of antelopes so due to this variation, the predator such as lion can catch the slowest antelope that is present in the population while on the other hand, the faster antelopes can save their lives by running very fast. Variation is present in a population of antelopes due to availability of food as well as genetic characteristics. These variation leads to the availability of food to the lions.

Answer:

Temporal Isolation

Explanation:

Temporal isolation relates to the time at which organisms mate. If a group of organisms mate in the winter and another group mates in the summer, they won’t mate together. This can cause speciation to occur. Hope it helps :)
