14.75mph
Explanation:
Given parameters:
Distance traveled = 177miles
Time of arrival in Dallas = 12hours
Unknown:
Average speed = ?
Solution:
The average speed is the total distance covered divided by time taken for the entire travel.
It is the rate of change of distance with time.
Average speed = 
since total distance traveled = 177miles, time of arrival = 12hrs
Average speed =
= 14.75mph

Every species has to adjust to climate change in one way or another.
They are genetically and reproductively isolated. For the mule the specific isolation mechanism is termed as "Hybrid Inviability", where the postzygotic isolating mechanism prevents the hybrid from passing on their genes. A zygote may form with the sperm and egg, but the embryo will dies after a few cell divisions. The genetic information from male and female parents is insufficient to carry the organism through morphogenesis. *There are rare documented cases of a mule producing a viable offspring.
Answer:
<u>Option-(True):</u> The following statement is true in all sense, as the "Cytotoxic T cells and NK cells kill by secretion of proteins. The first called granzyme which forms complexes that penetrate the cell membrane and allows the passage of the apoptosis inducing protein perforin to enter the targeted cell."
Explanation:
- In order to make it more difficult for the pathogens and other foreign particles to stay inside the human body, the defense mechanism of the human body system has evolved itself to great extents as there are different level of immune layers and more over cells that either helps in the recognition of these anti-bodies or attacks them to be eliminated from the given system.
- As the hazardous or cancer cells which are not required to stay inside the human body is removed with the help of these lymphocytes inside the immune system of the human body.
