Answer: biologists are a type of scientist that use dichotomous.

The Type of scientists that uses dichotomous key is : Biologist

A lot of scientists make use of the Dichotomous key for identifying unknown biological organisms like Biologists. A dichotomous key consists of a set of choices, with each choice consisting of two statements, these statements makes it possible to name an unknown biological organism.

A dichotomous key is a simply method used for the identification of organisms ( groups of unknown organisms are repeatedly divided into two groups to get more information about the organism )

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.

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:

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

"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:

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:

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.

The contents of the cell, or the structures of the cell, allow the cell to be "specialized". Together with the cell's proteins, they allow the cell to do specific things. They allow a cell to act like a neuron or a bone cell or a skin cell.

Explanation:

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

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.

The best wave represents ultraviolet rays is Wave B.

Ultraviolet (UV) radiation is a type of non-ionizing radiation that is emitted by the sun and unnatural sources, such as tanning .

Exposure to UV rays can cause early ageing of the skin and signs of sun harm such as creases , leathery skin, liver bumps, actinic keratosis, and solar elastosis.

UV beams can also generate eye pains. They can force the cornea to become inflamed or ignited.\
