Lipids would be the answer that you are looking for. When talking food energy it's best to speak in terms of calories. Therefore, lipids or fats offer the greatest amount of heat or energy.

What is the definition of refraction, luminescence, and ultraviolet?
jeyben [28]
Refraction- bending of light waves (ex. straw in a cup of water looks bent on a side but really is NOT, this is due to refraction, it bends the light waves reflected)

Luminescence- Creation/Emission/Starting or making of light through ways that DO NOT INVOLVE heat.

Ultraviolet- a wavelength that is part of the electromagnetic spectrum its shorter than visible light waves.

An organism's genome is analyzed and found to contain 18% guanine. What percentage of that organism's DNA is adenine?
Oxana [17]

Answer:

32%

Explanation:

According to Chargaff in his complementary base pairing rule, he stated that the proportion of purine and pyrimidine bases is equal to 100%

That is, A + T + G + C = 100%

Where A=T and G=C i.e the proportion of each base pair is equal.

Hence, if the Guanine content is 18%, it means the Cytosine content of that DNA molecule must also be 18%. Therefore:

18 + 18 + A + T = 100

A + T = 100 - 36

A + T = 64

If the sum proportion of Adenine and Thymine is 64% and each must contain equal proportions, A or T = 64/2 = 32

Hence, Adenine contains 32%, likewise Thymine.

Question 7 in the attachment, please help thank you so much!
sertanlavr [38]

Answer:

Here are the answers:

a. 4  Cell determination as an issue in the *rest is missing*

b. 4  They assumed that different ways of separating an embryo into two parts would be equivalent as far as the fate of the two parts was concerned.

c. 4  I and III only

Explanation:

The passage demonstrates the importance of two factors in the development of an embryo: cleavage planes of division of embryonic cells and cell differentiation.

Cleavage Planes:

Cleavage basically refers to the division of the zygote into a large number of cells called blastomeres. Cleavage planes are geometrical lines or orientations along which cleavage takes place. Since, all embryonic cells are the precursors of some type of body cells, the cleavage planes determine if the cells are adequate for growth and development.

Cell Differentiation:

Cell differentiation is the transition of an undifferentiated cell into a specialized one. For example, stem cells are undifferentiated cells that develop into progenitor cells that mature into a specific cell lineage. For an embryo to regenerate, the presence of adequate embryonic stem cells is crucial. Embryonic stem cells are present in abundance before the gastrulation phase of embryonic development, after which they rapidly start differentiating.
