Answer:
Just as oceanic crust is formed at mid-ocean ridges, it is destroyed in subduction zones. Subduction is the important geologic process in which a tectonic plate made of dense lithospheric material melts or falls below a plate made of less-dense lithosphere at a convergent plate boundary
Explanation:
<span>DIAPHRAGM. Actually the diaphragm is strongly attached to the base of sternum, then spine and also the ribcage at lower parts, So when diaphragm contracts, the length gets increases and also the diameter of chest, which expands the lungs, where the intercostal muscles controls and helps to move the ribcage and support in breathing, hence controls the size of the chest cavity.</span>
Answer:
The rate of reproduction.
Explanation:
It should be understood that poiklothermic animals are the animals that do not have constant body temperature. This means that their temperature changes in accordance to the temperature of the environment. Examples of such organisms are reptiles and Pisces, fishes, among others.
The homeothermic animals are the animals that are capable of maintaining their body temperature.
Homeotherm is usually applied to animals that can maintain a constant body temperature through metabolic processes endotherms.
It should be understood that endothermy is the process of maintaining body temperature through internally generated metabolic heat
Examples of endothermic homeotherms are bird and mammals, these animals have a high metabolic rate.
In conclusion, the population of poiklothermic animals are more than that of homeothermic animals because of the rate of their reproduction. The poiklothermic animals reproduce in high numbers when compared to the the homeothermic animals.
Ans.
In humans, there are total of 46 chromosomes in each cell that show 23 pairs of chromosome. During reproduction, meiosis occurs in germ cells that leads to formation of daughter cells or gametes that contain half of the chromosomes as present in parent cells. Thus, each gamete (either male or female) contains 23 chromosome.
During fertilization, fusion of male gamete or sperm(with 23 chromosomes) and female gamete or ovum(with 23 chromosomes) to form zygote that develops into multi-cellular offspring with 46 chromosomes.
Thus, 'a child inherit 46 chromosomes from his or her parent (23 chromosomes from each parent).'
Answer:
These features correspond to the plant kingdom.
Explanation:
Plants are non-motile autotrophic organisms, they can synthesize chemical energy by using sunlight (trough a process named photosynthesis). Moreover, plants play a critical role in the ecosystems since these organisms produce oxygen when they photosynthesize.
