Question is incomplete. Complete question is as follows:
All cells have
A. a covering called a plasma membrane that surrounds the cell and controls what information and materials enter and leave it.
B. An internal fluid that gives shape to the cell and supports the other things within it
.
C. A central zone or nucleus that contains the cell's genes.
D. All of the above
Answer:
D. All of the above
Explanation:
- All cells have a protective covering called plasma membrane. It allows the entry and exit of selective materials. Some cells can have an additional layer outside it which is called cell wall. For example, plant cells.
- All cells have an internal fluid where the components of the cell float. It is called cytoplasm or protoplasm. It maintains the shape of the cell and also provides a structure to it.
- All cells also have a zone where the genetic material is present. The genetic material is ultimately responsible for keeping the cell alive and forming various proteins. In prokaryotic cell it is present just in a zone in cytoplasm. In eukaryotes it is present inside an organelle called nucleus.
- Hence, all the above things are present in each cell.
If you mean classic doppler effect, the C would be correct.
Answer:
change blindness
Explanation:
Change blindness is the perceptual phenomenon which occurs when the change is introduced in the visual stimulus and observer is not able to notice this change.
People's Poor ability of the people to the detect reflect the fundamental limitations of the human attention.
<u>The given example in which the person is not able to notice the change which is the removal of the anchor, reflects change blindness.</u>
Answer:
the answer c. is correct
Explanation:
During DNA replication, the two parental DNA strands must be separated so that both strands can be copied. The resulting structure known as 'replication fork' is generated by helicase enzymes that break hydrogen bonds that hold DNA strands together, thereby the two strands of the DNA double helix uncoil at a specific location called the origin. DNA replication always proceeds in 5' to 3' direction. In consequence, a new DNA strand referred to as 'leading strand' is continuously synthesized because this strand grows in the same direction (5' to 3' direction) of the replication fork's movement, while other new DNA strand referred to as 'lagging strand' is synthesized discontinuously in short pieces called Okazaki fragments.
<span>Thyroid and Parathyroid Glands. The thyroid is a dual lobed gland located in the neck region. It secretes hormones that control metabolism, growth, heart rate, body temperature, and regulate calcium levels. Hormones secreted by the thyroid include thyroxin, diiodothyronine, and calcitonin.</span>
