If an enzyme has a single optimal temperature, then an organism might have difficulty dealing with an environment with wide temp

erature variation. What adaptive advantage is there in having repetitive enzyme systems (i.e., more than one enzyme to catalyze the same reaction) that we know many organisms have?

3 0

Answer:

Having a repetitive enzyme system would allow more than one enzyme to catalyze a particular reaction. If one of the types of enzyme is not able to perform its function due to temperature or any other factor, then another kind of enzyme would be able to catalyze the reaction. Hence, having repetitive enzyme systems is very effective in carrying out the metabolic functions of the body even when conditions are not favourable.

Earth is composed of layers of material with different properties. Which
Irina-Kira [14]

Answer:

mantle

Explanation:

A mantle is a layer inside a planetary body bounded below by a core and above by a crust. Mantles are made of rock or ices, and are generally the largest and most massive layer of the planetary body. Mantles are characteristic of planetary bodies that have undergone differentiation by density. All terrestrial planets (including Earth), a number of asteroids, and some planetary moons have mantles.

The work of Charles Darwin and Alfred Wallace on the origin of the Earth's species extended the ideas of Lyell's uniformitariani
Morgarella [4.7K]
<h2>The work of Charles Darwin and Alfred Wallace </h2>

Explanation:

C) uniform modification of genetic traits over long periods of time.

The theory of uniformitarianism  states that the natural phenomena and laws that are bringing about changes in the today's world are functioning in the same rate since the geological times. This idea of uniformitarianism was linked to biological sciences because according to Darwin and Wallace's observation, the uniform modification of genes among the population brought about the species diversity on the Earth.

What does the growth of lichens symbolise
horsena [70]

Answer:

I don't know exactly what the growth of lichens symbolizes in general, but I found the information about what does it mean for California state:

In 2016, according to The Mercury News (mercurynews dot com), Lace Lichen

becomes state symbol of California. The president of the California Lichen Society, Shelly Benson, said: " Lichens are widely overlooked. Our main mission was really to create more awarness about lichens and their role in the ecosystem."

As Lichen, widespread and may be long-lived, was chosen for a state symbol, its growth may symbolize the increase of state strength.

Which of the following statements regarding a DNA double helix is true? The amount of adenine is equal to the amount of thymine,
Elena-2011 [213]

Answer:

Option (1).

Explanation:

DNA (deoxyribo nucleic acid ) is the genetic material present in all the organisms except some viruses. DNA structure follows the Chargaff's rule.

Accoprding to Chargaff's rule, the ratio of purines to pyrimidines in a DNA molecule is equal to 1. The amount of guanine is nearly equal to the amount of cytosine whereas the amount of thymine is nearly equal to the amount of adenine.

Thus, the correct answer is option (1).
