Answer:
Molecules.
Explanation:
Molecules are the items that attach on the inside of the mineral to give the mineral its shape. The molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.
Due to the fact that, these molecules are structurally arranged or ordered and are repeated by different symmetrical and translational operations they determine the shape of minerals.
Explanation:
A. The differential induction of DNA transcription suggests the cells are destined to become different tissues.
Given the lack of RNA encoding, DNA transcription is not occurring. This may happen because the cells are destined to undergo different forms of differentiation- here, transcription would require the activation of different regions of the genetic code called transcripts.
Sequences of DNA make up genes which can have different forms called alleles. DNA is transcribed into mRNA and later translated into amino acids which are linked together by rRNA to form proteins.
Further Explanation:
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

Answer:
heterotroph and an invertebrate
Explanation:
Animals have been classified into being AUTOTROPHIC OR HETEROTROPHIC based on their nutrition while they are also classified as VERTEBRATE OR INVERTEBRATES based on their skeleton. A heterotrophic animal is one which depends on other organisms to obtain energy or food while an invertebrate is an animal that lacks a vertebrae column or backbone.
In this case, caterpillars are said to feed on many leaves before it makes a cocoon and becomes a butterfly. This means it relies on plants (leaves) for food, hence, it is HETEROTROPHIC. Also, it has an exoskeleton i.e. skeleton present outside the body. This means that it does not possess any bone inside to form the backbone, and hence it is an INVERTEBRATE.
Answer:


Explanation:
In RNA (ribonucleic acids), the nitrogen bases are:
- Adenine
- Guanine
- Cytosine
- <em>Uracil</em> (there is thymine in DNA, but not in RNA)
The bases pair like:
- Adenine (A) with Uracil (U)
- Cytosine (C) with Guanine (G)
So, the base pairs for RNA are <u>A with U </u>and <u>C with G</u>
Answer:
b. Works within an upper and lower range
c. " Is regulatory. "
d. Is very common in biological systems
Explanation:
Negative feedback is the regulatory mechanism that maintains homeostasis by counteracting the deviation. Any change serves as a stimulus and a response is produced to reverse the change. Negative feedback is a very common regulatory mechanism to maintain internal body conditions within a narrow range.
For example, the body temperature in adults is maintained within the narrow range of around 36 -37 degrees Celsius. An increase or decrease in the body temperature from the set point is counteracted to restore the set point. An increase in body temperature is reversed by the vasodilation of blood capillaries of skin layers to lose the heat to the surroundings. On the other hand, reduced body temperature below the set point is restored by constriction of capillaries of skin layers.
