Answer:

cork (thin slices of cork)

Explanation:

Robert Hooke used the term "cell" in 1665. He made the first compound microscope, and he used it to see the cork cells. He took thin slices of cork and examined it under the compound microscope. He found smaller compartments in it. These compartments were arranged like a honeycomb structure. The cork was a dead plant part, hence inside of each compartment was empty. He called the outer wall is the cell wall.

Methapyrilene refers to an anticholinergic and antihistamine of the pyridine chemical category that was formulated in the initial 1950s. It was traded under the names Histadyl EC and Co-Pyronil.

It exhibits comparatively strong sedative influences, to the degree that its main application was as a medicine for insomnia in spite of its antihistamine activity.

What would you expect to happen to levels of mevalonate in human plasma if an individual were to go from a meat-containing diet

enyata [817]

Answer:

increase

Explanation:

The mevalonate pathway is known to generate isopentenyl pyrophosphate and dimethylallyl pyrophosphate, which are used to synthesize diverse compounds including cholesterol and steroid hormones. The levels of mevalonate in human plasma may be used as a measure of cholesterol synthesis. When the cholesterol level is low, it stimulates its endogenous production by the mevalonate pathway. Since it is well known that the vegetarian diet reduces cholesterol, this diet also increases mevalonate levels.

If present, the ________________ allele will always be expressed as the phenotype.

k0ka [10]

Answer:

Dominant

Explanation:

The dominant allele will always be shown in the phenotype if it's present, because the other allele would be dominant or recessive. If both alleles are dominant, then the dominant one shows, if one of the alleles is recessive, then the dominant allele would show over the recessive one.

I think of recessive alleles as "weak" where, they just follow behind whichever other allele exists there. If the other one is dominant, then the recessive one is behind it, and no one can see it. If it other allele is recessive, a recessive allele will be in front.
