Answer:
The leaf discs only float in bicarbonate solution and in the light environment.
Explanation:
The bicarbonate dissolves in water to produce a source of inorganic CO2 in the reaction:
NaHCO3 + H2O → H2CO3 + OH- + Na+
Then, the HCO3- undergoes fixation through several complex steps in order to form a carbohydrate or sugar. These store the converted solar energy in their bonds as chemical energy to be used in metabolism.
Photosynthesis is a chemical process, essential to plant and other primary producers producing energy. Energy in the form of glucose molecules is derived from solar or light energy, water, and inorganic carbon dioxide, while it releases oxygen (from the light reaction). The leaf discs float as O2 gas is produced, making them buoyant.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
Carbon dioxide + water + energy= glucose + oxygen
<span>Answer: A) Dark moths had a survival disadvantage in industrial Dorset.
-----
This question can be solely answered using the data you're given! The graph is broken down by place, and then moth type.
In forested Birmingham, the green bar for the light moth is much higher than the orange one for the dark moth. That means the light moth had a survival advantage (eliminating option D) and the dark moths had a survival disadvantage (eliminating option C).
In industrialized Dorset, the green bar for the light moth is much lower than the orange one for the dark moth. That means the light moths were at a survival disadvantage (eliminating option B). The dark moths were are a survival advantage, but option A says "disadvantage," which is clearly wrong! That makes A your answer.

Answer:
deoxyribonucleic acid in short DNA
It is a double helix
It is a molecule that contains the instructions an organism needs to develop, live and reproduce.
<em><u>translation in dna</u></em>
DNA translation is the term used to describe the process of protein synthesis by ribosomes in the cytoplasm or endoplasmic reticulum. ... tRNAs carry particular amino acids, which are linked together by the ribosome. In this process, the mRNA is decoded to produce a specific amino acid chain, known as a polypeptide.
Answer:
C
Explanation:
Before the earthquake the gene pool of the parent population was bigger and carried different alleles for a lot of genes.
After the killing of 98% of the population, the surviving one has an incomplete representation of the original gene pool. We can think of this as a gene bottleneck ; the new allele frequencies will be different that the parental population. IE: broadness of stripes has a higher frequency after the earthquake.
Yes, they do. The chloroplasts contain chlorophyll (aka green pigment) and is where photosynthesis takes place. Animals obviously don't photosynthesize, which is how you can remember that animal cells do not have chloroplasts.
