The homeostatic control system component which transmits the response is called the receptor.

To add, the receptor is an organ or cell able to respond to light, heat, or other external stimulus and transmit a signal to a sensory nerve.

3. Symmetry

Explanation:

Some important traits that influence the reproductive success of a flower include: the presence or absence of whorls, the fusion of organs to one another, and the overall symmetry of flowers.

In the process of reproduction in plants, the male and female gametes are produced and transfer of the male gametes to the female ovules occurs. This process is called as pollination. After pollination occurs, fertilization happens and the ovules grow into seeds within a fruit

Floral zygomorphy confers a reproductive advantage to rare plants" as a result of the enhanced pollination efficiency.

Compare and contrast the extracellular matrix of animals and the cell wall of plants. Consider their functions and the types of

Answer:

The plant cell wall is strengthened by the molecular structure of cellulose. Cellulose is made up of ß-glucose arranged upside down, this arrangement aided hydrogen bonds between the hydrogen ions of the hydroxyl group and oxygen of the of the ring of same betta -glucose.

The aggregation of the hydrogen bonds give bundles of strong tensile strength of cellulose called the microfibrils (of 60-70 celluose molecules).They are held together in bundled called fibers.These is the source of plant cell walls strength.

Collagen is the main extracellur matrix (EM) in animal cells.It is a glycoprotein made up of 25%of body protein of animals.Each collagen molecule is made of helix shaped ,three polypeptide chains, wound around each other to form triple helix.The bonds holding helix together are hydrogen and covalent bonds.

Each triple helix is attached to adjacent collagen molecule, parallel to it. The covalent bonds formed a cross link which held the collagen molecules together forming FIBRILS. This gives flexibility to collagen, while maitaing strong tensile strength. This is what is responsible for the structural strength of cell membrane .

.The EM,is futher reinforced with carbohydrate molecules(proteoglycans) which aided in water movements by osmosis following sodium movements into the matrix.

A cross country runner runs 8 km in 2 minutes. What is his speed?

oee [108]

The speed of the cross country runner is equal to 4 km/min.

Given the following data:

Distance = 8 km.

Time = 2 minutes.

To determine the speed of the cross country runner:

Speed can be defined as the distance covered by an individual per unit time and it can be measured in kilometer per minutes (km/min).

Mathematically, speed is given by the formula;

$Speed = \frac{distance}{time}$

Substituting the given parameters into the formula, we have;

$Speed = \frac{8}{2}$

Speed = 4 km/min.
