Answer:
Cell membrane and cytoskeleton
Explanation:
The cell membrane is the outer covering that encloses the cell contents and regulates movement of materials in and out of the cell. the cell membrane gives the cell its structure. Cytoskeleton provides support to the cell and include three types of small networks:
Actin filaments: - are flexible double strands of the protein actin
. They lead the intracellular movement of organelles and molecules and stabilize mechanically the plasma membrane
.
Microtubule: - are rigid hollow cylinders of the proteins α- & β-tubulin
They are responsible for the position and stability of ER and Golgi-Apparatus
, help to divide & move chromosomes during mitosis and organize the growth of the cell wall
.
Intermediate filaments: - are robe like fibres of different proteins which give
mechanical support
<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>

Answer:
Cold blooded
Explanation: all mammals are warm blooded they prouduce milk to feed their young and they have hair. Cold blooded animals are lizards and stuff related to that.
Answer No 1: False
No, we will not expect the ant population to decrease over time. This is because in our experiment we have included aphids to an area of tree canopy. We expect to see an abundance in the ant population as the population of aphids is increased. We expect these results on the basis of our previous observations.
Answer No 2: True
As seen by our observation that the number of ants increase if we increase the number of aphids, we can deduce that the ants might have a mutualistic relationship with the aphids. As a result, if we remove ants from a tree, the aphids will also decrease from the tree.
Answer No 3: False
Our control in this experiment cannot be two different species of ants as we are studying the mutualistic effects of ants and aphids. Hence, introducing two types of ants will have nothing to do with our hypothesis.
