Answer:

False, but be sure you read what follows.

Explanation:

False: Heart disease and Most Cancers are not viruses. Or at least as far as I know. However complicating the issue is the fact that after a viral infection, heart disease can develop.

Cancer is another example, and the answer again is not black and white. 16% of all cancers can trace their beginnings to a bacteria or virus. That leaves 84% whose beginnings are not that clear.

The question is not black and white. I'd be careful how you think of it. If something is a complication, is that a direct cause? I still think the answer is false, but don't be surprised if your instructor disagrees. Move on to something a little less black and white.

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

Which of the following is a postzygotic isolating barrier?

Jet001 [13]

Answer: The following is a postzygotic isolating barrier :

The hybrid offspring of two species of crocodiles can produce normal gametes but cannot obtain a mate.

Explanation:

Reproductive isolation occurs when barriers prevent two populations from interbreeding , keeping their gene pools separate.

We can find the Prezygotic isolation that occurs before fertilization can happen.

And the Postzygotic insolation barriers are the reproductive insulation processes that act after the mating. They are all that concern the viability of the individuals produced.

Prezygotic isolation barriers can be temporal, behavioural, geographic , ecological or mechanical; whereas postzygotic isolation barriers include the inviability, infertility or breakdown of hybrid organisms
