Answer: B. secrete enzymes that kill bacteria
Explanation:
Paneth cells, so-called because they were first described by Dr. Josef Paneth in 1888, are pyramidal cells, with the nucleus in the basal position, and with large granules in the apical position. Its first isolated specific product was the lysozyme, a bactericidal substance, by Alexander Flemming. These cells play an important role in innate immunity in the small intestine, producing a wide diversity of antimicrobial peptides and enzymes such as lysozyme itself, cryptidines, defensins and a lectin with bactericidal properties.
Answer:
I would say it is E.
Explanation:
because fish, penguins, and dolphins are aquatic animals. It can't be A. because if it were vestigial it would be useless. It can't be B even though it does seem like the right answer because the are all aquatic. It can't be C. because it would been that the same species would have the same niche which is not possible. It can't be D. because every organism is evolved from a common ancestor.
Answer:
A the temperature increases.
Explanation: When the same amount of water is heated or cooled, its density changes. When the water is heated, it expands, increasing in volume.
Answer:
The glyptodon is found to be similar to the armadillo.
Explanation:
A piece of evidence that supports the theory of evolution is that the glyptodon is found to be similar to the armadillo. Glyptodons and armadillos have many things in common, expect that glyptodons are much larger (the size of a Volkswagen beetle!) than an armadillo. The change from the prehistoric glyptodon to our modern day armadillo helps support that there is evolution because they still have many things in common. They are genetically related.
Correct answer: D). The organism is buried in sediment and then dissolved by underground water
Mold is a copy of an organism, it is formed like the first layer of sediments harden and forms a mold. Then after that new layer of sediment fills and become hardens.
The fossil is left behind in sediment, which removes the remains of an organism from its surrounding material. The groundwater along with its mineral content dissolves the organic matter to form the fossil.
