Soaring and gliding birds like eagle, vulture, albatross, sea gulls etc are efficiently adapted to utilize the air currents in their flight.
Explanation:
The soaring flight and gliding movements are special adaptation developed by birds to meet the challenge of increasing turbulent air current.
Birds have the extraordinary skill of flying smoothly and effortlessly even at very high altitudes
Birds soar by using thermal and dynamic soaring techniques.
Gliding movements help the birds to deflect the wind downward which helps to lift their bodies in the air. They do not flap their wings during gliding but just dive straight into the air which helps to increase their speed.
The adaptation of the bird’s structure with very light but strong bones on their wings helps to soar and glide in the air.
Answer:
A. volcanic ash layers were regularly interspersed between the sedimentary strata.
Explanation:
The discovery of a fossil is a moment of accomplishment for archaeologists, hence the date dating process begins and the older the relic the greater its value for paleontology. Chemistry is present in this process, more precisely the carbon element, but other elements can be used as uranium, lead, potassium and argon.
In the case of the fossils reported in the question, to assign absolute dates to fossils in this sediment core would be most useful if volcanic ash layers were regularly interspersed between sedimentary strata because it would separate sedimentation times and allow the use of more than one element. dating, making the search more complete and the date most credible.
Answer:
Height is affected by multiple pairs of genes on different chromosomes.
Explanation:
The quantitative traits are those whose inheritance pattern is the result of the action of multiple genes that act together with the environment. The distribution of quantitative traits in the population follows a bell-shaped curve, which is referred to as normal distribution or Gaussian distribution. These traits are 'quantitative' because they vary among individuals in the population to produce a continuous range of phenotypic values. Examples of quantitative traits include, among others, metabolic rate, height, and weight.
