Answer

• state a hypothesis to be tested

<u>Development rate increases faster with temperature that growth rate</u>

• describe how the control group will be treated differently from the experimental group

<u>The control group will be raised at 8 different temperatures to assess their size at maturity, and their asymptotic size.</u>

• identify the independent variable in the experiment

<u>3 clonal lines that differ in asymptotic size and growth rate.</u>

• identify the type of data that will be collected

<u>Measurements of the individual length of Daphnia</u>

Explanation

In this experiment, the temperature-size rile(TSR) was utilized where it will be found that responses on temperature size observed at maturity is different from that manifested at asymptotic size. It will be observed that thermal shift in resources allocation may completely or partly result to a thermal plasticity in maturity size. Moreover, it will be seen that thermal plasticity in asymptotic size is controlled by temperature related challenges.

<span>An experiment is where scientific data is gathered and analysed to form inferences. Moreover, we can establish a testing ground on the daphnia population, let say by embryology. Hence, we can observe ina controlled manner how temperature influences the growth and formation of offspring by mothers of the daphnia population considering that offspring can contribute to population growth. </span>

Darwin examined remains of extinct organisms while on his journey. The remains had been preserved in rock for a very long time.
garri49 [273]
The remains are called fossils. Fossils are remnants of animals, plants, or microorganisms that have been solidified in the process of fossilization, where the organism is surrounded by sediment, minerals, and other solid objects which are compressed and heated around the organism over time. This forms a solid mass with the preserved organism inside, other known as a fossil.

Which of the following characteristics are true for an action potential?
pickupchik [31]

Answer:

I, II, III

Explanation:

A threshold stimulus is a stimulus that is capable to produce a response in excitable tissues such as neurons and muscle fibers. At threshold potential, the outward movement of K+ and inward movement of Na+ become equal to each other. When the potential exceeds the threshold potential, more and more Na+ enter the cell to depolarize it and to allow the opening of Na+ channels. Therefore, to fire an action potential, the threshold must be exceeded.

Conduction of action potential is all or none phenomenon which means that either it occurs or it does not occur. As an impulse is passed by each successive part of an exon, it enters the refractory period during which there is no conduction of nerve impulse. It ensures the one-way conduction of impulse from the cell body to the axon terminal only.
