Unlike fully aquatic marine mammals, or Cetacea, sea otters are bi-terrestrial and are capable of living on both land and in the water. Like all marine mammals, otters have webbing between their toes with acts like a flipper as well as a streamlined body to enable them to move quickly through the water. The only adaption that is not applicable to otters is <span>d. breathing apparatus on the top of the head.</span> Only marine mammals such as whales, dolphins, and porpoi have a blow hole on their dorsal side of their body. Another difference from Cetacea is an otter's thick fur. I believe the ratio for pelt density is one million lock of fur per square inch. Otter fur is also much longer compared to that of other marine mammals like pennipeds. Their long fur makes otters especially susceptible to oil and oilspills resulting from underwater oil mining accidents.
The probability of progenies to have red flower is 50%.
<h3><u>Explanation:</u></h3>
The phenomenon where the two pure alleles of a particular character present in an individual gives a mixed appearance is called incomplete dominance, where the dominant character cannot fully mask the presence of a recessive character.
Here In the cross between a red flowering plant and the pink flowering plant, the character shows the incomplete dominance.
Let the allele for dominant character i.e red flower be R and recessive character white be r.
So the genotype for red flowering plant = RR.
The genotype for pink flowering plant =Rr.
The gametes from red flowering plant =R.
The gametes from pink flowering plant =R and r.
So with the cross, the genotype of the offsprings will be 50% RR and 50% Rr.
So plants with red flowers will be 50% of the whole progeny.
Answer:
transform
Explanation:
Most earthquakes occur at the boundaries where the plates meet. In fact, the locations of earthquakes and the kinds of ruptures they produce help scientists define the plate boundaries. There are three types of plate boundaries: spreading zones, transform faults, and subduction zones.
