The rodenticide warfarin was originally introduced during World War II and has continued since then. Although it was initially v

ery successful, its effectiveness has lessened over time because of an increase in resistance among some target populations of rats. For instance, among Norway rats in Great Britain, resistance results from an otherwise harmful mutation R in a gene in which the normal sensitive allele is denoted S. In 1985, R.M. May (Nature 315:12-13) calculated the relative fitness of the SS, SR, and RR genotypes in the presence of warfarin to be 0.68, 1.00 and 0.37, respectively. The reduced fitness of the RR genotype appears to result from an excessive requirement for vitamin K.
Required:
In the presence of warfarin, what is the value of the selection coefficient s for this population of rats?

Sponges have no nerve tissue or sense organs.explain why this means that sponges have no cephalisation.
arlik [135]
Cephalization is the differentiation of end part of the body into a head in which nerve tissue is concentrated. Sponges have a very loose nervous system and their cells work individually, not controlled by a nervous system. Since they have no defined head as a consequence of concentrated nervous system, the sponges could not have cephalization either.

True or false: Most muscles contain a combination of all three muscle types, slow oxidative, fast oxidative, and fast glycolytic
kkurt [141]

Thanks to what we know about muscles and the fibers they contain, we can confirm that the statement in the question is in fact true.

Muscle is a type of tissue which due to coordinated systems that make up their composition, have the ability to contract. This ability allows for greater efficiency. In humans, the muscle systems are classified into three kinds:

  1. Cardiac muscle
  2. Skeletal muscle
  3. Smooth muscle

Despite the different classifications and functions of each muscle type, each of these muscles contains a combination of three types of muscle fibers, which are the fibers listed in the question:

  1. Slow oxidative
  2. Fast oxidative
  3. Fast glycolytic.
