Hypothalamus
When there is abnormally high internal temperature, sensors
in the Central Nervous System send signals to the hypothalamus. The hypothalamus initiates thermoregulation
by sending messages to various organs and body systems with a various
mechanisms. High temperature will set off sweating and vasodilation to cool down
the body.
Answer:
Option D, 75%
Explanation:
Let the genotype of co dominant checkered hen mates and checkered rooster be CcC and CcC
Where Cc – is the allele for chekered skin
C – is the allele for non chekered skin
Co-dominant allele are those which irrespective of being dominant or recessive are expressed equally.
The punnet square for the cross between these two would be
Cc C
Cc CcCc CcC
C CCc CC
3 out of 4 offsprings have chekered allele i.e CcCc, CcC and CcC. Thus, the probability of chekered offsprings would be 75%
Answer;
-DNA molecule
Explanation;
-According to cell theory; All known living things are made up of one or more cells. All living cells arise from pre-existing cells by division. The cell is the fundamental unit of structure and function in all living organisms.
-The modern version of the Cell Theory includes the ideas that:
-
Energy flow occurs within cells.
- Heredity information (DNA) is passed on from cell to cell.
- All cells have the same basic chemical composition.
-Therefore the study of DNA molecule was instrumental in the formulation of the modern cell theory.
