B.225,000km
C.22,500,000km
D.225,000,000km

Answers

The answer is (D.) 225, 000, 000 km

AU means astronomical unit. It is used by the astronomers to measure large distances in the Solar System. 1 AU is the average distance from Sun to Earth which is 149, 598, 000 km.

So to get the km value of 1.5 AU.

1.5 x 149, 598, 000 = 224, 397, 000

Round off to 225, 000, 000

Answer: D. 225,000,000km

Explanation:

An Astronomical Unit is the average distance between the Earth and the Sun. It is a unit of length which is used to measure distances in our galaxy.

1 astronomical unit is approximately equal to 150 million kilometers. 1 million is $10^6$ .

Thus 1 Astronomical unit (AU) is equal to 150 million km or $150* 10^6km$

So 1.5 Astronomical unit (AU)= $(150* 10^6)/(1)* 1.5=225* 10^6km=225000000km$

Thus correct option is D.

Which of the points of natural selection is also referred to as "survival of the fittest"? More offspring are born than can be supported by the environment. If too many offspring are born, they will be forced to compete for resources. Genetic variation leaves some offspring better adapted to their environment than others.

Answers

The third one is the answer.The first one is overproduction.The second one is competition.The third one is survival of the fittest, because if there are six grey mice and two brown mice in a brown field, which is more likely to be eaten by a predator? The grey mice are. Their genetic material helps them to survive and therefore be fit to their environment.

Pablo is using micropropagation to grow a variety of plants. What difficulty may Pablo face in his work? The cell wall of some cells may not be easy to remove. He will need a large number of seedlings just to produce a few plants. He will need access to a large outdoor space for growing plants. Some of the tissues he cultures may need a complicated culturing medium.

Answers

Answer:

this is you answer

Explanation:

Micropropagation is the artificial process of producing plants vegetatively through tissue culture or cell culture techniques. In this artificial process of propagation, plants are produced invitro by asexual means of reproduction or by vegetative propagation.

Plants can be produced both asexually i.e, via vegetative parts’ multiplication or sexually i.e., seed production. One of the means of asexual reproduction is by multiplying genetic replicas of plants that are referred to as clonal propagation wherein plants can be populated from a single individual through asexual means of reproduction.
