Answer:
b) positive feedback loop
Explanation:
The frontostriatal loop is an example of a positive feedback loop.
Hey there!
Let's start with the first blank. The ozone layer starts in the stratosphere and is made of ozone gases made to protect the Earth from the Sun's harmful UV rays. If the ozone layer wasn't there (not to mention the rest of the atmosphere), we would be exposed to that kind of radiation. Thereofe, "Ultra violet rys would not be <u>blocked</u> by the ozone layer."
For the next one, a lot of levels of substances in the air would change, like UV and oxygen- as there would be more radiation from the lack of protection and all the oxygen would escape.
Hopefully this helps!
Answer:
A. A resource that is so scarce (in restricted quantity) that it limits the size of a population is called a limiting factor. Any single resource can be a limiting factor to a population size. For example, the amount of water available can affect the number of plants that can grow in an area.
Since ALD is an x-linked recessive disease, women must have 2 affected x chromosomes in order to get the disease, which is unlikely because the disease is rare. Since men only have one x chromosome, they will have the disease if they inherit an affected x chromosome.
Answer:
second)some of the energy disperses as heat
Explanation:
This second law of thermodynamics states that in the course of conversion of energy from one form to another in an organisms,this can not be 100% efficient ( there is constant increase in entropy of the systems in the organism)as some of the energy is dissipated as heat in the course of conversion.
Thus in a food chain as energy is been converted from one trophic level( primary consumer) to another( secondary consumer) these organism makes use of the energy to do biologic work.Therefore as this is passed to other organism in the tropic levels not all the initial energy will be available ,as some has been lost during biology work,respiration , excretion ,movements and locomotion. in the subsequent organisms.
Thus the entropy of the organisms involved increases as energy is been transmitted from one trophic level to another which leads to heat dispassion.
