The conditions depend on the density level of the snow.

Another reason is the imperfect data gathering especially if initial results are only gathered.

The third reason is that computer models still find it difficult to see small scale phenomena.

All the gametes of isogamous organisms are genetically identical.<br><br> True<br> False

Lady bird [3.3K]

Answer:

False

Explanation:

Gametes are formed by meiotic division, and classified by shape, size and activity. In some species they are undifferentiated, that is, isogamous, resembling, but not identical, regardless of gender. However, most species have heterogeneous gametes (anisogamy), differentiated by morphological, dimensional and mobility aspects.

If a small droplet of ordinary fat molecules is suspended in water, the fat molecules form a "ball of spaghetti" with no particu

kolbaska11 [484]

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
