Answer:

Some enzymes require the addition of another non-protein molecule to function as an enzyme. These are known as cofactors, and without these enzymes remain within the inactive.

Ierofanga [76]

First we can look at the taxonomic order:

Domain
Kingdom
Phylum
Class
Order
Family
Genus
Species

The largest level would be the one closest to the top of the list because it is the least specific and therefore the most inclusive. Out of the choices given, phylum is closest to the top, so that is the answer.

How does the diameter of each ripple change as time passes

VLD [36.1K]

The diameter of the ripple changes by the following equation = $\frac{dA}{dt} = \frac{\pi }{2} D . \frac{d(D)}{dt}$

Explanation:

When a pebble or a rock is dropped in the water then the ripples or waves are formed which starts moving radially outward. As the time passes, the radius of the circle increases.

Let D be the diameter of the circle.

$\frac{dD}{dt}$ will be the rate of change of diameter of the circle with respect to time.

Let A be the area of the circle.

$\frac{dA}{dt}$ will be the rate of change of area of the circle with respect to time.

Area of the circle = $\frac{\pi }{4} D^{2}$

So,

$\frac{dA}{dt} = \frac{d [\frac{\pi }{4} D^{2}] }{dt}$

$\frac{dA}{dt} = \frac{\pi }{4} \frac{d[ D(t)^{2}] }{dt}$

Using chain rule,

$\frac{dA}{dt} = \frac{\pi }{4} X \frac{d[D(t)^{2} ]}{d[D(t)]} X \frac{d[D(t)]}{dt}$

$\frac{dA}{dt} = \frac{\pi }{4} . 2D(t) . \frac{dD}{dt}$

$\frac{dA}{dt} = \frac{\pi }{2} X D(t) X \frac{d(D)}{dt}$

$\frac{dA}{dt} = \frac{\pi }{2} D . \frac{d(D)}{dt}$

Thus, the following equation determines the change in area in terms of diameter with respect to time : $\frac{dA}{dt} = \frac{\pi }{2} D . \frac{d(D)}{dt}$

Nutka1998 [239]

Answer:

1. D. Only DNA contains genetic information

2. D. Nitrogen and Phosphorus

Explanation:

1. Lipids are insoluble in water unlike other molecules. It stores energy within the fat tissues and cushion internal organs against trauma.

Carbohydrates are sugar units such as monosaccharides, disaccharides molecules which makes up starch that is fuel to your cells.

DNA is a type of nucleic acid that contains genetic information which influences your personal characteristics.

2. The family Rhopalodiaceae has the ability to perform nitrogen fixation, which allows diatoms to fix atmospheric nitrogen. And phosphorus has been found in some diatom species in the Black sea region which does not affect its reproduction rate and also helps in carbon cycle.
