Cell theory states that all living things contain one or more cells. Why do you think cell theory meets the definition of
a scientific theory? Do you think it should be a scientific law? Explain your response.

Answers

Answer 1

Yes. Scientific laws are established statements, based on repeated experiments or observation of a particular scenario or natural events while a science theory are events or explanation of the natural world that can be repeatedly tested and verified using scientific method. That is, for it to be a Scientific Theory we must be able to test and verify it using scientific methods and for it to be a Scientific Law it must have been tested and verified repeatedly using scientific methods. Cell  theory is a tested and verified experiment

i am generally found both inside and outside of the nucleus {in eukaryotic cells} is it DNA O RNA ?

Answers

Answer: RNA

Explanation:

Nearly all the RNA found in a typical eukaryotic cell is rRNA. Transfer-messenger RNA (tmRNA) is found in many bacteria and plastids.

What is generally found both inside and outside of the nucleus of a eukaryotic cell is ; RNA

RNA is formed in eukaryotic cells when DNA contained in the nucleus of the cell is transcribed/synthesized. The transcribed RNA is then moved out of the nucleus into the cytoplasm.

The RNA contained in the cytoplasm is later transcribed into protein in the cytoplasm of the cells . therefore RNA is contained both inside and outside the nucleus of a eukaryotic cell.

Hence we can conclude that what is generally found inside and outside the nucleus of a eukaryotic cell is RNA

B. He was the first to observe live cells in a sample of pond water.

Explanation:

He was a self taught man that created the first microscopes which allowed him and others to see tiny organisms.

A scientist has discovered a new plant species in the Amazon rainforest she tells her fellow scientist at the Playhouse she has found for Tuesday is a cone for my side about this plan is different from an organism

Answers

Answer:

It is a seeded vascular plant.

It does not depend on insect pollination.

Explanation:

The complete question is: A scientist has discovered a new plant species in the Amazon rainforest. She tells her fellow scientists that the plant she has found produces a cone. What might they say about how this plant is different from an angiosperm? Its seeds have one or two cotyledons. Its stems' vascular bundles are scattered. It does not depend on insect pollination. It is a seeded vascular plant.

The correct option would be that the plant is a seeded vascular plant and does not depend on insect pollination.

Gymnosperms are the only group of plants that produce cones. They are one of the plant groups that have vascular tissues in the form of xylem and phloem as well as been able to produce seed in the form fo cones. Hence, they are said to be seeded vascular plants.

Gymnosperms also carry out their pollination by relying solely on wind for the transfer of their pollen grain to the female organ. In other words, they do not depend on insect for pollination.

in the term 2pq of the Hardy-Weinberg equation. Why is the multiplication by two necessary?
PLEASE HELP ME!!!!!

A-The term is multiplied by two because the effect of both the alleles is taken into account.

B-There are two ways that a heterozygous individual can arise: either by receiving a recessive allele from the egg and a dominant allele from the sperm, or by receiving a dominant allele from the egg and a recessive allele from the sperm

C-The frequency of the dominant allele is doubled because of its stronger effect on the phenotype.

D-The term is multiplied by tvo to account for doubling of the population in each generation.

Answers

Answer:

The correct answer is : option B.

Explanation:

Hardy–Weinberg equilibrium is a mathematical model that states that genotype percentage or frequency in a population and allele in a population remains stable or constant to generations if there are no evolutionary influences present.

Hardy Weinberg equation is :

            P²+2pq+q² = 1

Here, p² represents the frequency of genotypes dominant homozygotes (AA) in a population in equilibrium. The term 2pq represents the frequency of heterozygotes (Aa)  as there are two ways of developing heterozygous individuals either dominant from the egg and recessive from sperm or vice versa. and the term q² represents the frequency of recessive homozygotes (aa).  

Thus, the correct answer is : option B.

There are two ways that a heterozygous individual can arise: either by receiving a recessive allele from the egg and a dominant allele from the sperm, or by receiving a dominant allele from the egg and a recessive allele from the sperm, the frequency of the heterozygous allele is multiplied by 2 (option B).

The Hardy–Weinberg equation is an equation which expresses the principle of Hardy-Weinberg equilibrium.  The Hardy-Weinberg equilibrium states that in the absence of external evolutionary factors which disturbs equilibrium, the amount of genetic variation in a population will remain constant from one generation to the next.

The Hardy Weinberg equation is given as: p² + 2pq + q² = 1

In the equation above,

represents the frequency of dominant h0m0zygotes (AA)represents the frequency of recessive h0m0zygotes (aa),2pq represents the frequency of heterozygotes (Aa),p represents the allele frequency of the allele A and q represents the allele frequency of the allele a.The sum of all the three frequencies equal to 1 representing all the possible allele combinations.

Since there are two ways that a heterozygous individual can arise: either by receiving a recessive allele from the egg and a dominant allele from the sperm, or by receiving a dominant allele from the egg and a recessive allele from the sperm, the frequency of the heterozygous allele is multiplied by 2.

Mammals that live in the Arctic Ocean have a large amount of blubber, which is a fatty tissue just beneath the skin.
Which statement best relates why these animals have so much blubber?
O Lipids in blubber insulate the animals from cold water.
O Proteins in blubber help the animals move to stay warm.
O Carbohydrates in blubber provide all the energy that the animals need to stay warm.
O Nucleic acids help build the lipids in blubber, which keep animals warm by regulating cell activities.

Answers

Answer:

Lipids in blubber insulate the animals from cold water.

Explanation:

Lipids are fatty tissue, or fats in the cells. Blubber is fat. The fat helps insulate animals from cold water, especially in the Arctic known for being freezing. Fats can help maintain and keep body heat, hence why skinnier people are colder. Without lipids, they would most likely freeze.

Which is one way that minerals crytallize from materials dissolved in water
From the air
From solutions that evaporate
From hot water solutions when water boils
From the soil

Answers

Answer:

From solutions that evaporate

Explanation:

Minerals can form in different ways. According to the question, minerals crystallize from a material dissolved in water when the solution evaporates. When a material dissolves in water, it forms a solution i.e. water + dissolved material.

The element constituents of the solution can aggregate to form a solid mineral, which will be left to crystallize when the solution undergoes evaporation i.e. liquid changes to gas. A very good example is when salt dissolves in water to form a salt water solution. When the water of this solution evaporates, salt crystals are left, which can crystallize to form minerals.

From solutions that evaporate
