The method used above involves the determination and comparison of the genes of the three species of finches. So, the answer is
<span>(3) Obtain molecular evidence from all three species and identify similarities.
</span><span>The genetic makeup of the three species will show different similarities that can be used to relate the evolution of the different species.</span>
Answer:
E. Mangroves have only one type of root system
Explanation:
Mangrove species are those species of plants found in a saline environment. The soil they are found is usually shallow and swampy (water-logged). They possess characteristics feature that helps them adapt and survie in their habitat.
One of those features is the possession of PNEUMATOPHORES OR BREATHING ROOTS, which is a kind of root system that extends out so that the pores on them can allow the intake of gases directly from the atmosphere.
Answer: option C) negatively charged and contains less sodium
Explanation:
In the absence of any stimulus, a neuron is said to be resting. During this time, more positively charged potassium ions (K+) than sodium ions (Na+) occupy the interior of its cell membrane, whereas more sodium ions than potassium occupies the exterior - making the cell membrane to be electrically Polarized with net positive charge outside and a net negative charge inside the cell membrane.
Thus, the interior is negatively charged and contains less sodium ions
<span>This is avoidance conditioning. Brenda has been able to successfully link the over-the-counter heartburn medicine to an avoidance of discomfort. By taking the pill, she has received a negative reinforcement due to the removal of the indigestion. The reinforcement will likely lead to Brenda continuing to take the medicine until she habituates to it and does not receive the same benefit(s).</span>
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.
