The answer is D) 1/2.
Let's imagine that two genes of the genotype can be analysed separately.
Black fur is determined by dominant allele B. In this case, parents Bb and BB will give offspring with only brown fur:
Parents: Bb x BB
Offspring: BB BB Bb Bb
Both homozygous (BB) and heterozygous (Bb) offspring will have black fur.
On the other hand, long tails are determined by recessive allele t. Parents Tt and tt will have 50% offspring with short tail and 50% offspring with long tail:
Parents: Tt x tt
Offspring: Tt Tt tt tt
Heterozygous offspring (Tt) will have short tail, and homozygous offspring (tt) will have a long tail.
So, the offspring will definitely have black fur and will not affect the fraction of the offspring with black fur and long tails from the cross of <span>BbTt × BBtt. But, </span>there will be 2 out of 4 offspring with short tails which is 50% or 1/2.
The type of communication style that someone would have if they worry about the thoughts and feelings of others rather than their own is passive.
C. passive
<u>Explanation:</u>
4 main communication styles are passive, aggressive, passive-aggressive and assertive. People with a passive communication style find it difficult to express themselves. They usually have the fear that their feelings won’t b respected and tend to behave in a way by considering the feelings of other people while ignoring their own.
Lack of eye contact, poor body gesture etc are the signs of passive communication. The lack of ability to communicate outward often results in passive communicator’s getting misunderstood.

Answer: To kill the bacteria causing the illness
Explanation:
When a person takes antibiotics, the bacteria causing diseases will be severely hampered in its operations which will lead to the symptoms of the disease reducing. The bacteria will not die until the drug is taken as prescribed which is why the full dosage must be taken.
If it is not, the bacteria can regain strength and start causing sickness again except this time, it may grow an immunity to the antibiotics which means that an even stronger dosage of antibiotics will be needed.
