It's the rod cells that see better in dim lighting, so D
Cell division is the process in which the cell divides into two or more daughter cells whereas cell differentiation is a process in which embryonic cells become specialized cells according to their function.
DNA amount changes in cell division but no change in DNA in cellular differentiation.
Explanation:
During cell division, either mitosis or meiosis will take place in somatic or germ cells resulting in 2 diploid and 4 haploid cells respectively. The daughter cells are responsible for repairing or gamete formation. The amount of DNA content doubles in cell division.
In cell differentiation cells become specialized for the functions they have been destined like blood cells, nerve cells etc. Different types of cells are formed because different genes are expressed for the specific function. Hence, there will be no change in DNA only the sequence of DNA dictates the specialized cell for the particular function.
If the solute concentration is equal both inside and outside of the cell it is isotonic
Answer:
The options
a. 3:4
b. 3:1
c. 4:3
d. 4:9
e. 1:3
The CORRECT ANSWER IS e.
e. 1:3
Explanation:
Compound A (green) , GENE A is transformed to Compound B (blue)
Compound B (blue) , GENE B is transformed to Compound C (red)
After gene A as transformed the compund A to compound B, gene B can can transform the compound B to C. Therefore, once gene A is forming blue colour from green, gene B as the capability to form red colour from the blue one.
Lets cross AaBb X AaBb (the product of the cross is shown in the attached image. )
we will have the following genotypes:
AABB-1
AABb- 2
AaBB-2
AaBb-4
We obtain a functional copy of A and B gene from the cross. Thus, the transformation of colour will proceed from green to red and they will form red colour, giving us 9 red colour.
AA bb -1
Aa bb -2
The functional B gene is absent in these organism while the funtional A gene can be seen, thus only blue colour will be formed or 3 individual will give the blue colour.
aa BB -1
aa Bb -2
aa bb-1
these set of individual will not give or form any colour as they do not possess the functional A gene which is a requirement for starting the cascade of transforming the compounds.
Therefore, the blue to red offspring will be
3:9 or 1:3
The CORRECT ANSWER is e.
Answer:
C. respond selectively to objects.
Explanation:
The neurons in the inferior temporal cortex are involved in:
- Responding selectively to the objects.
- Letter and pseudoword reading
- Grapheme-phenomic conversion
- Audiovisual integration of syllabus
- Presentation of faces pronouncing syllabus.
Hence option C is the right answer amongst the options mentioned.
