<span>DNA methylation is a process that can change the activity of a gene without rearranging the DNA sequence. The mechanism most often is used to inactivate genes.</span>
Answer:
Bacteria that are oxidase-negative may be anaerobic, aerobic, or facultative; the oxidase negative result just means that these organisms do not have the cytochrome c oxidase that oxidizes the test reagent. They may respire using other oxidases in electron transport.)
The correct answer is neuroplasticity.
Neuroplasticity or brain plasticity is the property of the brain to change. Neuroplasticity can be observed at different levels. For example, changes at the cell level can affect connections between neurons (synaptic plasticity), while non-synaptic plasticity refers to changes in the intrinsic part of the neuron. On the other hand, larger-scale changes are usually made by environmental stimuli. Emotions may cause neuroplastic change through activity-dependent plasticity, which is significant for the recovery from brain damage.
The arachnoid mater meninges are in the middle of the outer and inner meninges. The arachnoid mater is the central of three layers that create up the meninges or membranes that setting the spinal cord and brain. The dura mater is the outmost cover of the meninges and the innermost cover that outlines thoroughly to the many folding and gaps of the brain is named the pia mater.
The correct answer is Option B: 3%.
In 2016, Sub-Saharan Africa, doubling time is 23.3 years, thus Growth rate is 3%.
<h3>What is doubling time?</h3>
- The doubling time is the time taken by a population to double in its size.
- This concept is applied to population growth, inflation, resource extraction, consumption of goods, the volume of malignant tumors, and many other things that tend to grow over time.
- There is an important relationship between the percent growth rate and its doubling time known as “the rule of 70”: to estimate the doubling time for a steadily growing quantity, simply divide the number 70 by the percentage growth rate.
- Therefore, Growth rate is 70 divided by doubling time (70/ doubling time).
- Here, Doubling time= 23.3 years.
- Growth rate= 70/23.3= 3%
