The plants having wide tips (trait A) retain the moisture, which means they are more prone to infection. So, the number of plants having trait A would be the most affected among all, and their number will significantly decrease, or may become extinct.
The plants having drip tips (trait B) drains away all the moisture, which means, they are less prone to fungal infections. So, the plants having drip tips would be the more abundant as compared to other traits.
The plant having mid-tip (trait C) retains a little amount of moisture. So, the plants having mid tip may or may not be infected, so, they can also survive, but the survival rate would be less than the drip-tip plants.
So, it can be concluded that plant having trait B would be most abundant in future, and plants having trait B would be less than plant having trait B, and the plant having trait A would either be extinct or least present.
Answer:
Because the promoter region is initiation sites for transcription to occur.
Explanation:
Transcription is the first process of gene expression in both eukaryotic and prokaryotic cells. Transcription involves the synthesis of a complementary RNA strand from a DNA template. It is carried out by an enzyme called RNA polymerase which binds to the DNA molecule and adds nucleotides based on the sequence it reads on the DNA.
On the DNA molecule, are sequences of nucleotides which the RNA polymerase recognizes and binds to in order for the transcriptional process to start. These sequences are called PROMOTER regions. They are located upstream i.e. after initiation site, of the DNA. Without these promoter region, RNA polymerase cannot bind to the DNA molecule and hence transcription cannot occur.
The answer is B. Think of it this way. You always give insulin with a meal cause they need to raise their blood sugar. Glucagon is given when the blood sugar is too high and needs to come down.
Due to the <u>mutation </u>accumulation, the <u>binary fission</u> in bacterial population will decrease due to in ability to divide (Due to inactive replicating enzymes). In the similar way, the <u>generation time</u> will also decrease.
Binary Fission- Binary fission, also known as asexual body division into two new bodies, When an organism divides into two halves (cytokinesis) by binary fission, it doubles its genetic material, or DNA, with each new creature acquiring one copy of the latter.
Generation Time- The amount of time it takes for a colony of bacteria to double in size is known as the generation time. The generation period for various bacteria ranges from a few minutes to many hours. Bacteria multiply by geometric progression because of binary fission.

Answer:
The functions of plant organs Leaves absorb sunlight, and make food for the plant by photosynthesis.The stem supports the leaves and flowers. It also transports water and nutrients between the roots and the leaves. Reproductive organs allow a plant to produce new plants.
