Answer:
The correct option is 3. "At pH 6.5 the enyzme is 50% active"
Explanation:
For the titratable group to be protonated and cause the enzyme to be in the active state, it needs to have gained a hydrogen cation (H+). In order for that to happen, there must be enough hydrogen cations in the environment of the enzyme, and hence, an acidic pH is required in this case.
The genetic code is directly related to polypeptides and proteins in the sense that genes are decoded to synthesize proteins.
What is the genetic code?
Genetic code is the set of rules by which the sequence of bases in DNA are translated into the amino acid sequence of proteins.
The genetic code is unique for living organisms and is used to synthesize the proteins that is responsible for various activities in living organisms.
The genes in the genetic code are first transcribed into mRNA, which is then translated into proteins (polypeptides).

Seedless plants genetically alternate between generations.
<h3>What is the reproduction cycle of seedless plants like?</h3>
All seedless vascular plants have very similar life cycles. As in bryophytes, their life cycle has two alternating generations:
- the gametophyte
- and the sporophyte.
- The sporophyte is always the dominant and free-living generation.
With this information, we can conclude that seedless plants genetically alternate between generations.

The scientific method is a process of steps in order to get a conclusion. First, a scientist will observe something. It could be really anything. Then he/she will ask themselves a question. Like how does it do that? Or why does it do that?
Then they will form a hypothesis. This is where you will ask yourself what will be the outcome of the experiment.
Next you actually perform the experiment. If the experiment comes out as your hypothesis predicted, then you accept your hypothesis.
If not, you reject your hypothesis.
Of course, in science you just don't do one experiment. You do it multiple times and even with different circumstances.
Answer:
Option A
Option D
Option F
Explanation:
During the process of continuous starvation for a long period of time, the primary source of energy in body is hepatic gluconeogenesis which is responsible for producing endogenous glucose. Also lipolysis takes place in the adipose tissue to release fatty acid which is then converted into ketone bodies through though mitochondrial β oxidation and ketogenesis. The liver communicates with extrahepatic tissues, including adipose tissue and skeletal muscle and deliver glucose and ketone bodies to muscle and other extrahepatic tissues as fuels.
Hence, option A, D and F are true.
