Answer: Microtubules are found in cilia and flagella .Microtubules are the thickest type of cytoskeleton fiber .Structurally they are hollow tubes that can dissolve and reform very quickly.Functionally, they provide movement to the to the organelles and pull the chromosome to their poles at the time of cell division . In cilia and flagella the microtubules are organised in such a way that it becomes a circle of nine double microtubules on the outer side and two microtubules in the center.

Answer:

Explanation:

The pulmonary artery carries de-oxygenated blood from the right ventricle of the heart to the lungs. It is the only artery that carries de-oxygenated blood. This blood is usually from the tissues and has a lot of carbon dioxide from the cellular respiration of cells around the body. The blood is pumped to the lungs to be oxygenated and the carbon dioxide expelled.

If the flowers contain 50,000 kcal of energy, about how much energy will the lizard obtain from eating the butterfly? 500 kcal 5

Triss [41]

500 because of the 10% rule when moving up in food chains, for example; patch of grass-200J rabbit eats some of it but doesn’t eat all - 150J the rabbit runs around for a bit and loses energy, the fox doesn’t eat all of the rabbit - 50J ( just a rough example may not be completely right but the concept of the rule is there and the energy).

When dna replicates each strand of the original dna molecule is used as a template

SVETLANKA909090 [29]

When DNA replicates, each strand of the original DNA molecule is used as a template for the synthesis of a second is known as complementary strand. 5' side on top, broken arrow 3' side on bottom, non-continuous arrow called lagging strand. Continuous strand to 5 to 3 in complementary called as leading strand.

what is Okazaki fragments?

The Okazaki fragments also known as lagging strand that are joined together by the enzyme DNA ligase.

These leading and lagging strands only formed in the DNA replication and DNA polymerase is the enzyme which helps in DNA dependent replication. DNA polymerase forms two identical DNA strands from a single DNA molecule.

Natural selection relies on genetic variation. In any population of beetles, there are alleles for brown or green color. What ha

Savatey [412]

The correct order for natural selection can be summarized as:

1. Inherited variation: Individuals among the population exhibit inherited variation such as body color, body size, hair colors, voice properties, et cetera.

For example, the population of beetles: an equal number of green and brown beetles.

2. Competition: Organisms face the struggle for their survival.

For example, Natural habitat is in trees. Green leaves hide green beetles.

The brown beetles are noticed by birds in the area.

Birds eat brown beetles.

3. Selection: It leads to differential reproduction, that is, the organisms with adaptive traits tend to survive and reproduce more.

For example, green beetles reproduce in greater number than brown beetles.

4. Adaptation: The organisms with survival traits tend to survive more and pass their traits to the future generation.

For example, more green beetles survive than brown beetles.

5. Evolution: The change in allele frequency of the population takes place.

For example, beetle population changes from brown and green to mostly green beetles.

Thus, the correct order would be:

1. The population of beetles: an equal number of green and brown beetles.

2. Natural habitat is in trees. Green leaves hide green beetles.

3. The brown beetles are noticed by birds in the area.

4. Birds eat brown beetles.

5. Green beetles reproduce in greater number than brown beetles.

6. More green beetles survive than brown beetles.

7. Beetle population changes from brown and green to mostly green beetles
