Image result for Is work done when you carry a book across the room at a constant velocity

Work is not done when you carry an object forward. You may have learnt that carrying an object and moving horizontally at a constant velocity has no work done. The truth is, there is a slight amount of work done due to overcoming air resistance in the horizontal direction.

"No" according to the work energy theorem about work is done when there is a change in final and initial velocity. But if I use Work = Force x displacement, even though the velocity is constant there is still some displacement done by the (constant) force acting on it.

Difference between i) bacteriostatic and bactericidal and ii) broad and narrow spectrum?
Ludmilka [50]

Answer:

Narrow-spectrum antibiotics target a few types of bacteria. Broad-spectrum antibiotics target many types of bacteria. Both types work well to treat infections. But using broad-spectrum antibiotics when they're not needed can create antibiotic-resistant bacteria that are hard to treat.

Justify your answer by filling in the blanks. Both parents have white fur. way that this can happen is if their genotypes are bo
MissTica

Answer:

Both parents have white fur. <em>The only</em> way that this can happen is if their genotypes are both <em>homozygous (bb)</em>. Therefore, both parents pass the (b) allele to every offspring. When you combine two of these alleles, the resulting genotype is <em>(bb);</em> therefore, the resulting  offspring have white fur.

Explanation:

A homozygous trait can be described as a trait in which both the alleles for a gene are similar. A heterozygous trait can be described as a trait in which both the alleles of a gene are different. If an allele masks the effect of another allele, it is said to be dominant. the allele that gets suppressed is termed as recessive.

Hence, for a recessive trait to occur both the alleles of a gene should be homozygous recessive.

The punnet square for the above cross is shown below:

        b       b

b       bb     bb

b       bb      bb
