The frog is a vertebrate because it has a backbone that is made up of many vertebrae. This is the right answer:)))
Answer:
True.
Explanation:
Earth rotation can be defined as the amount of time taken by planet earth to complete its spinning movement on its axis. This ultimately implies that, the rotation of earth refers to the time taken by earth to rotate once on its axis. One spinning movement of the earth on its axis takes approximately 24 hours to complete with respect to the sun.
Basically, the effect of the Earth spinning on its axis on winds and currents is that, global winds will move along a curved path and therefore cause ocean currents to curve.
As a result of the Earth's rotation on its axis, a phenomenon known as Coriolis effect arises.
Coriolis effect occurs when circulating winds are deflected to the left in the southern hemisphere and to the right in the northern hemisphere.
Hence, rather than have this air circulating in a straight pattern, it is deflected to the left of the southern hemisphere and to the right of the northern hemisphere, typically in a curved path or pattern.
In conclusion, we can say that the deflection of fluids due to the rotation of earth is the Coriolis effect.
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
Answer:
The correct answer would be 25 percent.
It is the case when both the parents are heterozygous for the trait that is, both are Rr in genotype.
Thus, both the parents would produce two types of gametes one of which contain R and the other one would contain r.
The cross would result in the production of the offspring with three types of genotypes; RR, Rr, and rr.
The three genotypes would be present in the ration 1 (RR): 2 (Rr): 1 (rr).
Thus, only one out of four would be Rh- in phenotype. Hence, only 25 percent is the probability that the offspring would not be able to receive blood from either parent.
Answer:
Cooler conditions eliminated many warm water species, and glaciation lowered global sea level. However, during the Cambrian there was no significant ice formation. None of the continents were located at the poles so land temperatures remained mild.
