Answer:
Answer is below.
Explanation:
Photosynthesis is a process that involves three main actors (or ingredients); sunlight, water, carbon dioxide.
Statistics has it that there was no sunlight all through the day.
- Let's check then if there was availability of water and the gas carbon dioxide.
There was rainfall all day
- This means that some photosynthetic activity would take place.
What about the gas that plants breathe in?
- There is always substantial amount of CO₂ in the atmosphere.
A SECOND WAY TO LOOK AT IT IS:
by checking the two stages of photosynthesis.
- In the first stage, sunlight is the main actor. Sunlight is trapped and stored as energy in the chloroplasts of green plants.
- In the second stage, CO₂ is the main actor. With CO₂, the chemical compound - from the first stage - ATP is used to produce sugar and organic compounds which are the food of/for green plants.
The correct answer is Rr and rr.
F1: Rr x rr
F2: Rr Rr rr rr
F1 is the first generation, parents
F2 is the possible genotypes fo offspring
It means that there is 50%possibility for heterozygous (red eyed) and 50% for homozygous (sepia eyed).
Answer:
The correct option is D. Amino acids (and thus proteins) also have nitrogen atoms; thus, the radioactivity would not distinguish between DNA and proteins.
Explanation:
Nitrogen is an active constituent of amino acids which make up proteins. Nitrogen is also an active constituent of the nitrogenous bases which make up an organism's DNA.
Phosphorus is actively present in the DNA but amino acids lack phosphorus.
Our body is actively made up of DNA and proteins. If the nitrogen was radioactively labelled, the experimental results would be wrong as proteins also have nitrogen in them.
