Answer:
B. 2 : 0 : 2
Explanation:
In a punnet square, the alleles would be Tt, Tt, tt, tt. So, you have 2/4 or 50% of the genotype Tt, and 2/4 or 50% of the genotype tt.
Answer:
C.
Event A represents volcanic eruption and Event B represents creation of mountain ranges.
Sorry if it's wrong :(

Explanation:
Logistic growth is a measure of continuous growth of a population of individuals in such an environment where the resources are limited. Such type of growth pattern has a characteristic growth curve which is S-shaped or sigmoidal.
The equation for logistic growth is as follows -
Change in population size = 
Where,
N = size of population
r = intrinsic rate of increase
K = carrying capacity
The values of r, N and K are given in the question as 12, 30 and 40 respectively.
So,
A: ribosome C: translation
During transcription, the two DNA strands unwind and separate. Free ribonucleotides combine to the corresponding bases in the template strand, which is one of the separated DNA strands. These ribonucleotides will form a mRNA, which can leave the nucleus and enter the cytoplasm.
In cytoplasm, mRNA will be translated into protein by ribosomes. During translation, the mRNA inside the ribosome will be attached to tRNA molecules, which will then attract specific amino acids. Different tRNA molecules bond with the corresponding segments of the mRNA and different amino acids will be joining together by peptide bond. A protein is then produced.
Answer:
Please find the detailed explanation/description on how to use the light microscope to view a wet mount of a protist. The 9 structures mentioned in the question are in CAPS.
Explanation:
- Firstly, the slide containing the wet mount of the protist is prepared and placed at the centre of a lowered STAGE. The STAGE CLIPS over the sides of the slide are used to hold it in place.
- The revolving turret or nosepiece is turned so that the LOWEST POWER OBJECTIVE LENS is in position i.e. directly above the sample/slide. The SCANNING OBJECTIVE LENS, the lowest objective lens with power of 4x is used initially.
- The slide is viewed through the EYEPIECE, and the image is brought into focus using the STAGE KNOBS.
- The COARSE FOCUS KNOB is turned until the protist on the slide is brought into broad focus. The FINE FOCUS KNOB is then used to bring the image on the slide into sharp focus.
N.B: The OBJECTIVE LENS should not touch the cover slip on the slide during this process.
- When the protist on the slide is clear using lowest power objective lens, the revolver turret can be rotated to allow HIGHER POWER OBJECTIVE LENS.
- Due to higher magnification of the HIGH POWER OBJECTIVE LENS, the protist might need to be refocused using the FOCUS KNOBS.
