Ceruminous glands are ________. Ceruminous glands are ________. saliva glands found at the base of the tongue modified taste bud
kogti [31]

Answer:

Modified apocrine sweat glands

Explanation:

The ceruminous glands are similar to sebaceous glands, belonging to the group of sweat glands. These glands secrete a sticky material, the ear wax, that protects the thin skin lining the ear canal.

As soon as a dust, dirt or an insect enters the ear canal at the beginning of the ear wax, the wax retains, wraps and pushes it outside the ear canal.

This secretion is lubricating as well as acidic, which helps to kill potentially harmful bacteria and fungi in the ears.

3. How would you date a sample of rock that you suspect as being one of the earliest on Earth? (1 point)
Kay [80]
<span>If I were attempting to date a rock sample that I suspect to be incredibly old, i would use radioactive isotopes with a long half life. When dating rocks and fossils to discover approximately how old they are, radioisotope dating is used on igneous rocks found near fossils. Things like Uranium 235, which is an unstable radioactive isotope of elements, decays at a constant rate over time so can be useful in determining age.</span>

If bicoid mRNA is injected at the anterior end of an egg from a bicoid mutant mother, what would the phenotype of the resulting
JulijaS [17]

If the larva had one head at the posterior pole, it would be normal. The larva would have two heads, one at the front of its body and the other in the center.

What is bicoid mRNA?

When translated, bicoid protein forms a morphogen gradient that shapes the embryo's head and thorax if bicoid mRNA localizes to the anterior of the Drosophila egg.

How does the egg's bicoid RNA influence development?

According to recent research, Bicoid specifies the anterior of the Drosophila embryo in two different ways. It initially suppresses posterior development. It accomplishes this by attaching to and preventing caudal RNA, which is distributed throughout the egg and early embryo, from being translated.
