I think you b and c is the other way around.
Regardless, the answer is Two elephants
The air pressure on your body is about 10kg same as the weight of 2 elephants
The Afrikaners are an example of a founder effect that occurs when population and the random decrease in genetic variation is an example of genetic drift.
Explanation:
When some individuals from a population move to form a new colony, this phenomenon is called founder effect as in case of Afrikaners. The small population or group of individuals forming a new colony may not exhibit the full genetic diversity of the population they were once the part.
The alleles would get expressed in different frequencies than it would have in original population.
There are chances that some alleles are lost or missing also. The new colony formed has small population so chances of genetic drift are very strong.
Genetic drift does not depend upon the benefit or harmful effect of the alleles as it occurs merely by chance sampling. The small population of Afrikaners felt the effect of genetic variation hence strong genetic drift is seen in them.
D. ATP (Adenosine TRIphosphate) has one more phosphate group and is higher in energy than ADP (Adenosine DIphosphate). TRI means three, DI means two, so the names of the molecules tell you there's one more phosphate in ATP than in ADP.
That extra phosphate makes ATP higher in energy (when the cell uses that energy to do something - contract a muscle fiber, for instance - the ATP's extra energy is used and it gets converted to ADP).
Answer:
a. all can be transmitted through contact with the rash/lesion
Explanation:
All the three diseases i.e. chickenpox, smallpox, and syphilis can be transmitted through contact with the rash/lesion.
Chicken pox: Chickenpox is a viral infection in which red blisters appear on the skin. It is caused by Varicella-zoster virus.
Smallpox: Smallpox was certified the global eradication by WHO in the year of 1980. Smallpox is a viral infection caused by the Variola virus. Variola viruses are of two types named Variola major and Variola minor.
Syphilis: Syphilis is a bacterial disease which is the most dangerous infection spread through sexual contact.
Answer:
I can think of several reasons
Explanation:
- Not all the offspring will survive until they are old enough to propagate
- Disease and accidents will kill some mature individuals before they can produce six offspring
- Predators will kill the weak and infirm individuals
- Poachers will kill every elephant they can find for their valuable ivory
- The land has a limited carrying capacity. Each area has a limited amount of resources available, so the population will level off as it approaches this limit.
