In a general partnership if ones partners actions cause the firm losses then

Answers

If a partnership is formed and one partner causes losses then both sides suffer.

Think of it like sharing a toy. If two kids are sharing a toy and one breaks the toy, then neither can use it. It's similar in this manner that if one partner makes a mistake then the entirety of the firm will suffer losses on both sides.

Answer:

All of the partners are responsible

Some insects can walk on the surface of water. Which behavior of water is responsible for this phenomenon? A. Capillary action
B. Solvent behavior
C. Surface tension

Answers

There are some insects that can walk on water, this phenomenon is possible because the water has surface tension. One animal that can walk on water is the lizard.

The behavior of water that is responsible for insects walking on the surface of water is surface tension. The correct option among all the options that are given in the question is the third option or option "C".Surface tension is basically the elastic nature of a fluid that helps it to acquire the least amount of surface area possible.

Suppose that a dominant allele (P) codes for a polka-dot tail and a recessive allele (p) codes for a solid colored tail. If two heterozygous individuals with polka-dot tails mate, what's the probability of the phenotype and genotype combinations of the offspring?A. 25 percent chance of a polka-dot tail and 75 percent chance of a solid colored tail (25 percent PP; 50 percent Pp; 25 percent pp)
B. 75 percent chance of a polka-dot tail and 25 percent chance of a solid colored tail (25 percent PP; 50 percent Pp; 25 percent pp)
C. 75 percent chance of a polka-dot tail and 25 percent chance of a solid colored tail (75 percent Pp; 25 percent pp)
D. 50 percent chance of a polka-dot tail and 50 percent chance of a solid colored tail (50 percent PP; 50 percent pp)

Answers

The answer is B. 75 percent chance of a polka-dot tail and 25 percent chance of a solid colored tail (25 percent PP; 50 percent Pp; 25 percent pp)

If P represents dominant allele (a polka-dot tail), p represents recessive allele (a solid colored tail), then heterozygous individuals have Pp genotype. All alleles will combine each other:

Parental generation: Pp x Pp
Offspring: PP Pp Pp pp

Thus, the probability of PP genotype is 1/4 (there is only 1 of total 4 possible genotypes), which is 25%. The probability of Pp genotype is 1/2 or 50%, and the probability of pp genotype is 1/2 or 25%.

Talking of phenotypes, the P allele is dominant and each genotype containing P allele will have the polka-dot phenotype. In this case, there are 3 out of 4 genotypes containing P allele - 1 PP and 2 Pp. So, the probability of the polka-dot tail is 3/4 or 75%, leaving the probability of the solid color tail 1/4 or 25%.

Because the United States imports about 4 billion barrels of crude every year, at best, the Arctic National Wildlife Refuge could provide us with nearly one hundred years worth of oil. True False

Answers

The given statement is false.

The Artic National Wildlife refuge could not provide the united states with one hundred year worth oil. The United states Imports about 4 billion barrels of crude oil.This refuge cannot supply united states with this much of oil because ever since it has became a refuge there has been no drilling and no seismic work has been done there.

False, the Arctic National Wildlife Refuge can not provide us with nearly on hundred years worth of oil.
