Answer:
negative, inhibition
Explanation:
The experiment in the illustration shows that early succession plants have a <u>negative </u>effect on the late succession plants, and the observation is most consistent with the <u>inhibition</u> model of succession.
<em>That the late succession plant thrives better in the absence of the early succession plants means that the early succession plant has been impacting the growth of the late succession plant negatively. This is consistent with the inhibition model of succession.</em>
There are 3 different models of succession. These include;
- Facilitation model in which colonists modify the environment to favor the growth of later successional species.
- Tolerance model in which early colonists' modification of the environment has no positive or negative impact on the growth of later successional species.
- Inhibition model in which early colonists modify the environment to inhibit the growth of later successional species.
Answer:
Malignant melanoma cells would have active telomerases that constantly replenish and lengthen telomeres.
Explanation:
Telomerase can be described as enzymes which add the repetitive sequences called telomeres at the end of a chromosome. Telomeres can be described as repetitive sequences at the end of the chromosome which are involved in protecting the chromosome from any damage.
In a normal skin cell, the telomeres will shorten with time. But in a malignant skin cell, the telomerase will add the repetitive sequence again and again. The telomers will not be able to shorten.
The sodium levels increase inside the cell during action potential. Opposite to resting state, depolarization is the shift of electrical charge resulting in positive charge inside the cell. Depolarization is the start of cell-to-cell communication and other necessary physiological functions of an organism.
Answer:
Explanation:
lemons contain antioxidants which prevent the fruits from browning
Schizocoelic development
The coelom is a fluid-filled body cavity, where the internal organs are suspended in. It is the cavity between the wall of the body and the digestive tract.
In the schizocoelic development of the embryo, the coelom, called the schizocoel, develops as a split in the mesoderm. The outer layer of the mesoderm attaches with the ectoderm to form a body's musculature, while the inner layer attaches with the endoderm to form the wall of the digestive tract.
This type of development is commonly found in annelids, arthropods, and mollusks.
