Answer - A
The ratio of a child with clear skin with that of freckled skin is 1:2.
When genotype rr mates with genotype Rr, the following genotypes are expected:
Rr = clear skin dominant
rr= freckled skin
Answer:
Option C (very coarse texture) is the appropriate one.
Explanation:
- Everything always cools quickly because once magma reinforces above that of the ocean floor and perhaps the shape it possesses seems to be agricultural context, color temperature, and so on. But as magma settles down underneath the layer, it gets sufficiently opportunity to solidify, culminating in a much more gritty texture as well as color change, respectively.
- We then assume that perhaps the assumption of whether concrete solidified buried underground correlates to a rather coarse framework.
Other decisions aren't linked to the circumstance issued. So the one above is indeed the best one.
Answer: a. Desert
Explanation:
The tropical climatic zone has three different biomes such as tropical rainforests, the tropical savannas and tropical deserts. The tropical climatic zone is the hottest of all the climatic zones as it can be found on and near the equator, this region receives the maximum sunlight energy year around.
Therefore, on the basis of the above information, the desert is the correct option. The desert biome is the hottest and driest region of the earth. This region receives very low annual rainfall.
The reason why sharks can swim fast is that unlike most fish, sharks have tails that are not horizontally symmetrical . Instead , the top of a shark's tail protrudes further back than the bottom , giving the shark lift while swimming and making it "spring" forward at speed.
Most fish make a single water "ring" that moves backward at the end of their tail's stroke but sharks are thought to produce two rings because of their asymmetrical tail which bespeaks a more efficient propelling action.
It has also been discovered that sharks can raise the tiny teeth-like structures called placoid scales on their skin to create tiny wells across the surface of their skin which reduces drag just like the dimples on a golf ball, thus enabling the shark move forward faster.
