<span> B. plutonic. An intrusive igneous rock is also known as plutonic</span> and has large crystals from slow-cooling magma. Types of intrusive rocks include gabbro, granite, dunite and diorite.
Answer:
C
Explanation:
Prokaryotic cells doesn't have any nucleus, so the first one is incorrect. No cell can function without genetic information, so the last one is incorrect. Plasmids are present only in Eukaryotic cells, so the second one is incorrect. Which leaves the third one as correct.
BMI<span> (body mass index), which is based on the height and weight of a person, is an </span>inaccurate<span> measure of body fat content and does </span>not take into account muscle mass, bone density, overall body composition, and racial and sex differences. <span>BMI is a substitute measure of body fatness because it is a measure of excess </span>weight<span> rather than excess body </span>fat<span>. Factors such as age, sex, ethnicity, and muscle mass can influence the relationship between BMI and body </span>fat<span>.</span>
There are choices for this question namely:
<span>A) genetic bottleneck.
B) sexual selection.
C) habitat differentiation.
D) founder effect.
</span>
The correct answer is founder effect. The definition of founder effect is the loss of genetic variation when a new population is established in a small number of individuals from a larger population. The larger population in the context is the ecosystem in Hawaii before it rose from the sea surface. After it rose above the sea surface, most organisms will not be able to survive in land but there will be a small population that can evolve from there.
Basically the seed contains 2 parts, the testa, which is the seed coat that protects the seed and cotelydon, which is the inside of the seed, containing the radical and plumle.
for seed to germinate, we need 3 basic conditions,
warmth, it is the suitable temperature for seed germination, it can influence the activity of enzymes. providing a optimum temperature
water, to soften down the testa so that the shoot can break out from the testa
and oxygen, for aerobic respiration
.
If these conditions are absent, the seed may be in the state of dormancy. where is won't germinate until it meets the suitable conduction.
after that, the enzyme will digest the nutrient inside the seed and provide amino acid, which is necessary to seed germination. and meanwhile the aerobic respiration provides energy, so that the plumlecan shoot out, and be the shoot of the plant.
and then until it grows leaves, it'll start to complete photosynthesis, instead of using the nutrients inside the cotelydon.
