b. a-hemoglobin is present only in cells where B-hemoglobin is absent
c. a-hemoglobin mRNA is more stable than B-hemoglobin mRNA
d. Tubulin inhibits translation of hemoglobin mRNA
Answer:
Answer is A. B-hemoglobin mRNA is translated more efficiently than is a-hemoglobin mRNA.
Explanation:
The introduction of electric charge into a gel or fluid, causing or resulting in the movement of the charged particles in the gel or fluid, is referred to as the electrophoresis. It can also be explained as a separation method or technique which is based on the movement of particles or ions in an electric field.
The electrophoresis is used in separating DNA fragments , RNA or protein, based on their size and charge.

Free Space Path Loss
The Free Space Path Loss in a bridged network will be the source of the greatest loss in the transmission.
Explanation;
-Free-space path loss (FSPL) is the loss in signal strength of an electromagnetic wave that would result from a line-of-sight path through free space (usually air), with no obstacles nearby to cause reflection or diffraction.
-Free-space path loss is proportional to the square of the distance between the transmitter and receiver, and also proportional to the square of the frequency of the radio signal. This value is usually calculated by discounting any obstacles or reflections that might occur in its path.
The network bridge can be the source of the greatest loss in a network's transmission. It can cause delays due to processing times and data queueing. However, impacts are usually minute and can be mitigated with advanced technologies.
In a bridged network, the source of the greatest loss in transmission can generally be attributed to the network bridge itself. This is because the network bridge operates by receiving, processing, and forwarding data from one network segment to others. During this process, the bridge may produce delays, also known as latency. This latency is caused by factors like processing times and data queueing, which could potentially result in a loss in transmission.
The impact of this loss is usually minute and almost imperceptible in smaller networks but can become more significant as the size and complexity of the network increase. Bridging technologies have evolved significantly to mitigate this impact, for example, by using intelligent forwarding algorithms and advanced hardware capabilities.

Answer:
There are several factors that can contribute to the effect an environmental toxin has on the human body. They are:
- Form and innate chemical activity
- Dosage, especially dose-time relationship
- Exposure route
- Species
- Life stage, such as infant, young adult, or elderly adult
- Gender
- Ability to be absorbed
- Metabolism
- Distribution within the body
- Excretion
- Health of the individual, including organ function and pregnancy, which involves physiological changes that could influence toxicity
- Nutritional status
- Presence of other chemicals
- Circadian rhythms (the time of day a drug or other substance is administered)
