Respiratory surface must be moist so gasses can diffuse across cell membranes
cells lining respiratory surface are thin to optimize gas fusion
respiratory surface are must be large to allow for adequate gas exchange
Fish species B would make a better model organism because at the end they produce 100 eggs more than fish species A.Fish species B is more likely to survive than Fish species A.
Answer:
Because it would mean severe muscle damage.
Explanation:
<h2>Maximum alleles</h2>
Explanation:
Maximum number of alleles that a person can carry is two
- A gene may have multiple alleles but a person can carry only two of those alleles because chromosomes exists in pairs
- Humans are called diploid organisms because they have two alleles at each genetic locus, with one allele inherited from each parent,each pair of alleles represents the genotype of a specific gene
- Gene determines a particular trait whereas alleles determines the variations in which a given trait can be expressed
- Human trait that is controlled by a gene with multiple alleles is blood group however only two of the alleles can be present in a single organism;ABO system of blood groups is controlled by three alleles, only two of which are present in an individual
