Answer:
conduction
Explanation:
Since ectotherms lack the capacity to generate heat within their body, one of the mechanisms they use in generating heat from the environment in order to maintain constant body temperature is, <em>energy transfer by conduction</em>. Conduction occurs when a lizard lays directly onto a hot rock.
Heat from the sun is transferred to the rock by radiation as the rock absorb the heat energy. This heat that is radiated in the rock is then transferred to a lizard that lays on it through conduction, and as the lizard absorbs this heat from the rock, they become warm.
- Energy transfer by conduction is mainly achieved through direct contact, and this is one of the methods that ectotherms like lizard rely upon to maintain constant body temperature.
It secretes high levels of thyroid stimulating hormone (TSH), this occurs in many poor countries where people are deficient in iodine and it causes there neck region (thyroid) to swell up.

Explanation:
one strength would be that the graph clearly shows the gases and pathway of the gases which are taken in and used in exhalation.
Answer:
1. Circulatory system is made up of your heart, arteries, veins and capillaries.
2. There isn't a photo attached. But Specialized cells perform specialized functions in multicellular organisms. Groups of specialized cells cooperate to form a tissue, such as a muscle. Different tissues are in turn grouped together to form larger functional units, called organs.
Explanation:
Answer:
The correct answer is option 4. Z
Explanation:
Given diagram representing a different level of organization where W showing organ which is the third smallest organization made up of different tissues.
X showing an excretory system that consists of several organs.
Y exhibits a cell that is the smallest organization in the human body.
Z is a tissue that is made up of cells joined collectively and the second smallest level of organization in the human body.
Thus, the correct answer is option 4. Z
And your welcome
