Answer:
Radiation leads to mutations that causes genetic drift and decrease fitness.
Explanation:
Radiation is responsible for changing or altering the DNA sequence within a cell.
Radiation either causes mutation or it leads to cell death.
Most of the ionizing radiation causes mutation within the deep inside of our cells which eventually leads genetic drift which means change in the frequency of the allele in a population over time.
Beneficial mutation confer advantage to the organism. But in this case, the mutation is not beneficial and decreases the fitness of the rodent organisms.
Answer:
The similarities that can be seen in the members of kingdom plantae and plankton is that both of them perform photosynthesis.
These organisms provide oxygen and food to the other members. These members get energy for living their life.
The planktons and the members of kingdom plantae requires nutrients for their growth and development.
The differences that can be seen in the plankton and members of plantae is that plankton are found on the surface of water.
The members of plantae can be found on the land, on the surface of water. But some of the species like brown and red algae are found in the depth of sea or ocean.
1. information is transcribed in DNA to mRNA
2. mRNA leaves the nucleus
3. ribosome attaches to the mRNA
4. tRNA anticodon carries an amino acid that compliments the mRNA codon
5. the chain of amino acid forms a protein
The question is incomplete as it does not have the options which are:
- Adjusts the positions of the head, the neck, and the trunk
- Perform respiratory movements
- Stabilize or position parts of the appendicular skeleton
- All of the above
Answer:
All of the above
Explanation:
The axial skeleton is the group of bones which forms the centre of the skeletal system. The central portion of the skeletal system includes bones of the skull, bones associated with the skull, the thorax, and the vertebral column (spinal cord).
There are 80 axial skeletal bones out of which 22 bones are present in the skull, 7 attached to the skull, 25 in a thoracic cage and 26 in the vertebral column.
The axial skeleton help maintains the position of the appendicular skeleton, maintain the posture of the body by maintaining the posture of the neck, head and trunk and also help in the respiratory movements.
Thus, all of the above is correct.
I believe the answer is heart, liver, pituitary gland, kidneys, and skin! hope this helped :)
