1.(a) (i) Explain why small organisms such as this amoeba can obtain sufficient oxygen for respiration without a
specialized gas-exchange system.?
fi)explain why the method of gas exchange in (a)i above is only possible in very small organisms.?

Answers

Answer:

In single celled organisms surface area to volume ratio is optimum for diffusion/exchange of substances between the cell and its exterior and this rate of exchange suffices the requirement of a unicellular organism. However, in multicellular organisms the surface area to volume ratio is low, the exchange that takes place with the exterior or the environment occurs only through the body surface with the help of a specific structure/organ, example (Skin),However, this exchange does not compensate for millions of cells in a multicellular organism, which have distinct requirements based on their function

Explanation:

i) Amoeba gets oxygen gas dissolved in surrounding water through its plasma membrane by the process of diffusion.

ii)The oxygen gas diffused inside the body is used up by amoeba. carbon dioxide gas is also liberated in the surrounding water through the same process of diffusion.

male

Explanation:

Females ovary always have a X chromosome.

Males sperms are of two types, they either have X chromosome or Y chromosome.

If X chromosome of males is involved in fission then, it results in XX chromosome set, it results in a female child.

If Y chromosome of males is involved in fission then, it results in XY chromosome set, it results in a male child.

How did the temperature relate to the “recommended temperature limit” (solid horizontal red line)?

Will give extra points for right answer

Answers

Answer:

The “recommended temperature limit” indicates limit of the temperature that is good for our world and above this limit causes adverse affect.

Explanation:

The temperature related to the “recommended temperature limit” means that in the graph there is a limit of temperature for our world's environment. if the temperature is between this limit, there is less or no adverse effect on our environment while on the hand, if the temperature exceeds from this limit, then it adversely affected our world because the concentration of carbondioxide gas in the atmosphere increases due to this increase temperature..

A gene consists of which of the following?

1) A sequence of amino acids that create a specific protein.

2) A sequence of tRNA that brings the correct amino acid to the ribosome.

3) A sequence of bases of mRNA that code for a specific protein.

4) A sequence of bases on DNA that code for a specific protein.

Answers

Answer:

answer is part (4)

Explanation:

A sequence of bases on DNA that code for a specific protein

4) A sequence of bases on DNA that code for a specific protein.

Gene:A gene is the basic physical and functional unit of heredity.Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins. Alleles are forms of the same gene with small differences in their sequence of DNA bases.Every person has two copies of each gene, one inherited from each parent.

Thus, option 4 is correct.

How does Einstein’s equation relate to the energy produced in nuclear reactions?

Answers

Answer:

hope this helps, im sorry if it dosent

Explanation:

An equation derived by the twentieth-century physicist Albert Einstein, in which E represents units of energy, m represents units of mass, and c2 is the speed of light squared, or multiplied by itself.

The equation — E = mc2 — means "energy equals mass times the speed of light squared." It shows that energy (E) and mass (m) are interchangeable; they are different forms of the same thing. If the mass is somehow totally converted into energy, it also shows how much energy would reside inside that mass: quite a lot.

Einstein's greatest equation, E = mc2, is a triumph of the power and simplicity of fundamental physics. Matter has an inherent amount of energy to it, mass can be converted (under the right conditions) to pure energy, and energy can be used to create massive objects that did not exist previously

The change in mass is related to the change in energy according to Einstein's equation: ΔE = (Δm)c2. ... The energy corresponding to the mass defect is the nuclear binding energy, the amount of energy released when a nucleus forms from its component particles.
