Answer:
The animals adapt to survive.
Explanation:
If a giraffe can't reach the food that another one can, that giraffe will die and the longer necked one wll survive. Adaptations over time cause evolution. The fittest will survive. (Darwinism)
Answer:
measure of the intrinsic luminosity of a celestial body (such as a star) expressed as the apparent magnitude the body would have if viewed from a distance of 10 parsecs.
Explanation:
Answer:
nonconformity
Explanation:
There are multiple types of unconformity that occur in nature, all of which are base on the relative position of the types of rocks. The nonconformity is one of the unconformities. This type of unconformity occurs when sedimentary rock overlies igneous or metamorphic rocks that existed there before the sedimentary rocks covered them. The nonconformity can be seen in lots of places around the world, but it is most common on places where there are water bodies like lakes, seas, oceans, ponds, marshes, or on places where there were water bodies of this type in the past.
<span>How are the dark reactions that occur in plants dependent on the light reactions?
a.The chemical energy used in the dark reactions is produced in the light reactions.
Photosynthesis is divided into two parts.
1) Light - dependent reaction
2) Light - independent reaction
Light dependent reaction absorb energy from the sun to produce ATP and NADPH, these energies are used in the light-independent reaction. The ATP provides the energy, while the NADPH provides the electrons required to fix the carbon dioxide into carbohydrates.

Answer:
d. induction
Explanation:
A repressor is a protein capable of inhibiting target gene expression by binding to both operator sites and gene silencers. A DNA-binding repressor inhibits the interaction between the RNA polymerase and the DNA promoter sequence, thereby suppressing transcription into RNA. Moreover, the RNA-binding repressor is a protein that binds to the messenger RNA (mRNA) molecule in order to prevent its translation into protein. An inducer can start transcription by interacting with the repressor, thereby separating it from the DNA operator sequence.
