The answer is; B
As air cools, its capacity to hold moisture reduces. This is is why as warm humid air cools, it reaches a saturation point, and the water moisture begins to form droplets. These droplets form clouds in the atmosphere.
Answer:
Biological hazary are natural scenarios involving disease, disability or death on a large scale among humans, animals and plants due to micro-organisms like bacteria, or virus or toxins.
The H1N1 virus (Cause 9f Swine flu) is believed to have begun its deadly journey in pigs from a small region of central Mexico in January 2009. By March, the first cases were reported in California and Texas. By June, it was in 74 countries across the globe. A year later, when the WHO declared an end to the pandemic, between 151,700 and 575,400 people had died.
A massive global vaccine effort led by the US helped end the pandemic, but the H1N1 virus is still with us. Every year it circulates as a seasonal flu, causing sickness, hospitalisation and dead
A: In a lab a scientist measures the height of roses that received different fertilizers.
An experiment must include variables. The other three are just measurements, but since the scientist is varying the types of fertilizers used, this better describes an experiment. It is also done in a controlled environment (in a lab) which helps to eliminate other uncertainties.
Answer:
a. Excretion is accomplished by paired protonephridia with flame cells in every segment of the body. True
Most anelids have structures called metanephrids or protonephridia. Both structures are homologous to the kidneys and have the function of excresion, A pair are present in every segment of the body.
b. If the organs in one segment fail, the organs of another segment will still function. False
It is false because all segments are interrelated and have different functions depending on their location.For example, the first segment is where the sensory appendages are, such as the antennae and the eyes. The second segment is where the mouth is. There are a series of parapod segments to move, collectively called metameres and ends in a terminal portion called pigidium, where the anus is located.
c. Annelids possess both circular and longitudinal muscles that produce waves of contraction that are propagated down through the points eBookseries of segments.True
True because anelids have circular and longitudinal muscles that serve to function the hydrostatic skeleton.
d. Segmentation has allowed for specialization in the anterior of the annelid body, which has provided for a more sophisticated nervous system. True
True because the segmentation allows to have a nervous system formed by a ventral nerve cord provided with ganglia and lateral nerves in each segment.
