Answer all The question
Question 11
Routinely, in nature, during a 24-hour period in nature, what substance do green plants continuously require and use?
a
oxygen
b
both carbon dioxide and oxygen
c
carbon dioxide, only
d

Question 12
Kali designs a set-up to investigate germinating pea seeds. She fills a jar with seeds that have soaked in water.
In the jar, she places a beaker that contains a solution of bromothymol blue. Bromothymol blue turns green in the presence of carbon dioxide.
She will record observations on Day 1, wait 24 hours, and record again on Day 2.
Which question has Kali MOST LIKELY ASKED as she set up this investigation?
a
Do germinating peas release carbon dioxide in the process of respiration?
b
Do germinating peas absorb water in the process of photosynthesis?
c
Do germinating peas release oxygen in the process of respiration?
d
Do germinating peas release water in the process of photosynthesis?

Question 16
If a FRAMESHIFT mutation causes a stop codon to be inserted into the DNA sequence
a
