Unlike green algae which can only live in water, a waxy covering over the epithelial cells of plants, called the ________ help(s

Pavel [41]

Answer:

Cuticle

Explanation:

Plant cuticle is a waxy covering over the aerial epidermal cells of all the plants. Waxes are composed of cutin and a various organic solvent-soluble lipids. The cuticle is an extracellular hydrophobic layer which provides protection against desiccation and external environmental stresses. In other words the cucticle helps to retain water and give plants an adavanthe to live terrestrial life.

How does a noncompetitive inhibitor decrease the rate of an enzyme reaction?

Wittaler [7]

Answer :B. By changing the shape of the enzyme's active site.

check the attachment

Explanation: This is a type of inhibition , in which a molecule binds to another part of the enzyme instead of the active site.

On binding, it disrupts the normal hydrogen bond and hydrophobic interactions holding the enzyme molecule in its three dimensional shape, therefore distorting the conformation and ACTIVE SITE of the enzyme (changed it shape).

Since the active site is the precise location enzyme must bind with substrates for enzymatic reactions,this makes the enzyme not fit for binding with the substrate, therefore the efficiency is reduced. No substrate-enzyme complex, and hence no substrate-product complex for the release of products, this brings down the turnover rate and eventually

the rate of reaction of the enzyme

Thus, the enzyme function is totally blocked, even in high concentration of the substrate,

In leghorn chickens colored feathers are produced by a dominant allele,

Gnesinka [82]

Basically the male will have CC, the hen will have cc, and neither of them will have I. The key thing is that _all_ the chicks are coloured.

The male must have at least 1 C to be coloured, and cannot possess the dominant I. The hen has cc and/or an I to not be coloured.

That one chick is coloured would tell you little - only that the hen couldn't have 2 inhibitor alleles because otherwise the chick would have to have one and it doesn't.

However, for all of many chicks to be coloured, that means that the hen can't have any inhibitor alleles (otherwise around 50% would be white for that reason alone).

So to be colourless, the hen must be cc. However, if the male had only 1 colour allele (ie it was Cc) that would still mean that 50% of the chicks would be Cc (daddy's 'c' and one of mummy's 'c's).

Hope this helps please award brainly :)

Which organelle stores water and helps to maintain the plant cell shape?

Evgen [1.6K]

Answer:

(D) H Vacuole

Explanation:

The vacuole is the organelle of the plant which contains water reserves of the plant and essential minerals required by the plant to grow. It also helps the plant to maintain its structure and provides rigidity
