sensory functions are found on the head of an insect , they have a single pair of antenna , mouthparts adapted for chewing or sucking.
The nonselective, passive process performed by the glomerulus that forms blood plasma without blood proteins is called filtration.
<span>Glomerular filtration is the first step in making urine which includes the<span> separation of the liquid part of the blood (plasma) from the blood cells</span>. Glomerulus of the kidneys (a tuft of blood capillaries)<span> filters excess fluid and waste products out of the blood into the urine collecting tubules of the kidney and thus eliminates it out of the body.</span></span>
Distribution of phenotypes within a population may be impacted by different types of natural selection. These types of selection include;
Directional selection involves a change in the environment shifts of phenotypes observed. Example is the giraffe neck-length, where the length got longer and longer over time to reach the leaves at the top of trees.
Stabilizing selection , this is a selection where an average phenotype is favored. example is number of eggs laid by birds such that too many eggs will be a waste of energy because some chicks would starve.
Disruptive selection is a selection where individuals with an average value of a trait are affected most while those with values below average are affected least. Example small individuals are capable of hiding from predators while big individuals can not fit in the hiding place but instead will fight with predators.
Answer:
The correct answer is option (e)-"All of the answer choices are correct".
Explanation:
Fossils are defined as the remains of ancient organisms. Fossils are obtained from impressions left after an organism decays. There are different kinds of fossils depending on the material they are made of and how they were formed. Some fossils are made from minerals that are the replacement of the organic matter of the ancient organism, or are the replacement of mud that came from footprints. Alternatively, fossils could be plant resins or tar that preserved a specimen within.
