Answer:
1.) The inner core's intense pressure—the entire rest of the planet and its atmosphere—prevents the iron from melting. The pressure and density are simply too great for the iron atoms to move into a liquid state.
2.)The Earth's magnetic field serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. One stripping mechanism is for gas to be caught in bubbles of magnetic field, which are ripped off by solar winds.
Explanation:
1. Gases are exchanged inside the
lungs through the surfaces of
thousands of alveoli to allow the
diffusion of carbon dioxide and
<span>oxygen
2. </span>Wastes are removed through the excretory system after passing through
either the kidneys urine or the digestive tract feces
3.Blood is redirected after a change in blood pressure after birth. Blood
now flows through the pulmonary artery to the lungs to receive oxygen
4. The lungs alveoli, the intestines, the
pulmonary artery, and the excretory system

Karyotype is written in the form: No. of chromosomes, sex chromosomes
As, we know there are 46 chromosomes in humans & sex chromosomes may be XX for females & 'XY' for males so, we can write it as:
(46, XX) or (46, XY)
There could be some anomalies though. So, for more appropriate answer, you should put your options!
Hope this helps! Pm me in case of doubt! Happy Studying :)
Answer: Elephants, humans, and bison are all k-selected species. On the other hand, r-selected species often inhabit unstable environments and are completely density independent. These species often have short life expectancies, produce as many offspring as they can, and invest very low amounts of parental care. You can see r- and K-selected strategies clearly by looking at different organisms within a phylogenetic group, such as the mammals. For example, elephants are highly K-selected, whereas mice are much more r-selected. Among the fishes, most, like the salmon, are r-selected. brainliest????
