Answer:
Exocrine glands secrete sweat and oil while endocrine glands secrete hormones.
Explanation:
As she knows the endocrine and exocrine glands in respect of their origin from skin, so our answer must be related to the skin so that she can understand easily. So our answer should be as follows -
- Endocrine glands are those glands which secrete hormones directly to the blood stream but exocrine glands are those glands which secrete sweat and oils directly to the skin surface.
- A duct is often present in exocrine glands but endocrine glands lack ducts.
<span>D. Vascular tissue
</span>
Vascular tissue is responsible for transporting water and nutrients in plants. <span> The Vascular tissue consists of the Xylem and the Phloem. The main function of the Xylem is to transport water and minerals throughout all parts of the plant. Phloem on the other hand is responsible for transporting organic molecules that are larger in size. The vascular system, consisting on the Xylem and the Phloem runs from the roots of the plats through the branches and upto the leaves. It controls the total transportation of the water and nutrients.</span>
Covalent bonds are formed when two atoms are able to <em>share</em> electrons.
Iroinic bonds are form when two atoms are <em> </em> electrons from each other to complete the bond. This results in a pair of ions.
<u>Covalent bonds:</u>
- Have a definite shape.
- Have a low melting point.
- At room temperature they are in a liquid or gas.
- They occur between two non-metals.
<u>Ionic bonds:</u>
- Have no definite shape.
- Have a high melting point.
- At room temperature they are solid.
- They occur between a metal and a nonmetal.
Answer:
results will be more accurate if there is a larger sample size.
No matter what research is, the larger sample size is, the more accurately will be the results and vice versa. The larger samples increase a chance of significance because they reflect the population mean more reliably.
With small sample, the chance for false conclusions is higher.
