During DNA Replication, the DNA molecule unzips itself so that there are two free strands of DNA. Both of those strands then create new complementary strands of DNA. Thus every subsequent generation of DNA uses one of the parent cell's strand of DNA as a template, which is why DNA replication is said to be semi-conservative. Hope this helped!
Answer:
Depending on the stimulus, graded potentials can be depolarizing or hyperpolarizing. Action potentials always lead to depolarization of membrane and reversal of the membrane potential. Amplitude is proportional to the strength of the stimulus. ... Duration of graded potentials may be a few milliseconds to seconds.

Explanation:
The Thyroid glands are butterfly shape glands madeup of microscopic spherical structures known as thyroid follicles made up of cuboidal follicular cells. These cells produces the both major hormones of thyroid gland T4, and T3.
The majority of thyroid hormones are produced as T4 hormones approximately 80% but a small amount of 20% is released in the form of T3 hormones. However, the most active form of the thyroid hormone is T3 and to act on target cells, one iodine molecule have to be removed to convert T4 to T3.
In an ecosystem, two factors are being classified which are the abiotic and the biotic factors. Both of these factors play an important role in order to balance the ecosystem and maintain the harmony of the living things therein. The environment includes the abiotic factors which are the sunlight, weather, water, air, and all other factors which are not living but contribute to the growth and development of the living ones. For example, plants cannot live without water, sunlight and carbon dioxide. The effects that humans have on the environment is both good and bad. Humans also play an important role in maintaining the environment, and they also have the capability to endanger it.
