Answer & explanation:
Fungi have long been regarded as organisms that were part of the <em>Plantae</em> kingdom (plants), mainly because they have cell walls in their cells, reproduce by spores, and the fact that some of them are sessile (attached to the ground).
However, fungi are no longer considered as plants because they do not have chlorophyll or specialized cells, such as chloroplasts and vacuoles. In addition, fungi have heterotrophic nutrition (plants are autotrophic), needing to absorb organic substances to survive.
Nowadays, fungi are studied in isolation and are inserted in their own kingdom, the <em>Fungi</em> kingdom.
The <u><em>correct answer</em></u> is:
He needs to select a more representative sample.
Explanation:
Choosing students from the basketball team for the sample he uses on a study of heart rates and exercise will be a biased sample. This is because students on the basketball team are potentially healthier than other students, which means that exercise will not have a large an effect on their heart rate as it would if they were not as healthy and not as physically fit.
In order to reduce the amount of bias, he should choose students from different groups throughout the school.
Answer:
they will add.
Explanation:
When a cell has energy available it can store small amounts of energy by adding a phosphate group to ADP molecules producing ATP molecules. The energy stored in ATP is released when ATP is converted to ADP and a phosphate group.
A force of 8 N will be required.
<h3><u>Explanation:</u></h3>
Mechanical advantage is defined as the ratio of output force from a system to the input force into the system. A machine which has the mechanical advantage more than 1 means it requires less force to give more force as output. Similarly, when the mechanical advantage for the machine is less than 1,it means more force is required to give to achieve a less one.
Here in the question, the mechanical advantage of the pulley is 2.
Output force required to pull the sack of potatoes upto kitchen is 16N.
Mechanical advantage = Output force / input force.
Or, 2= 16 / input force.
So input force = 
So a force of 8 N will be required to pull the pulley.
