For the first question the answer is D
For the second question the answer is B
Just as animals, plants also contain vascular<span> tissues (</span>xylem<span>), which transports water and minerals up from the roots to the leaves, and </span>phloem<span>, which transports sugar molecules, amino acids, and hormones both up and down through the plant</span>
Fungi produce spores that disperse from the parent organism by either floating on the wind or hitching a ride on an animal. Sporangium an important part of fungi are dispersed through a variety of means, such as being carred by wind, latching onto other organisms and even floating in wat
Answer:
Option 1, a charged end and a noncharged end
Explanation:
Complete question
If a small droplet of ordinary fat is suspended in water, the fat molecules form a "ball of spaghetti" with no particular orientation. But if a droplet of phospholipid molecules is put in water, all the molecules point outward, toward the water. Phospholipids are forced into this orientation because phospholipids have _____
- a charged end and a noncharged end
- three fatty acid molecules, all pointing in different directions
- two fatty acid molecules pointing in different directions
- both a saturated fatty acid and an unsaturated fatty acid
- two charged ends
Solution
The structure of phospholipids consists of the following groups and molecules –
a) A glycerol molecule
b) Fatty acids (2 in numbers) – It is hydrophobic as it is uncharged and non polar in nature
c) Phosphate group (with alcohol) – It is hydrophilic as it is negatively charged and polar in nature.
When the phospholipids are placed in water, the molecule rearranges itself in a way that the hydrophobic head face inside and the hydrophilic head face outside thereby forming micelles.
Hence, option 1 is correct
Answer:
molecule perform its function in order to share electrons and full its outermost shell electrons which is required for an atom to make himself stable.
Explanation:
what do you mean by perform its function?if you not understand again ask a question properly .thanks
