Answer:

Explanation:

We can easily move the box from a ground floor though to the first floor at an angle of 40° to the horizontal by simply pushing the load through an inclined plane. We will simply be lean the inclined plane on the building at the required angle and the push through the the height of the building.

Based on the explanation above, the best type of simple machine to use is an INCLINED PLANE. <em>Note that the essence of using a machine is simply to make our work easier and faster and also be able to overcome a much larger load with a minimal effort. </em>

Proteins around which the long, linear strands of DNA are wrapped; they serve to keep the DNA untangled and to enable an orderly
igor_vitrenko [27]

Answer:

The correct answer is- Histone

Explanation:

DNA is approximately 2.2 m long thread which has to be adjusted in a microscopic nucleus so DNA must be in a supercoiled form to be present in the nucleus and this supercoiling of DNA is done on histone protein.

Histone protein is a positively charged protein that is made up of eight proteins so it is called histone octamer. Each histone has 2 copies of each protein that is H2A, H2B, H3, and H4.

DNA is negatively charged and histone protein is positively charged therefore DNA wraps around histone protein which causes the packaging of DNA. So the correct answer is histone protein.

The answer is ‘behavioral isolation’. It is a form of sympatric speciation - which occurs even when species live in the same habitat. In this case, the individuals in the population are isolated by differences in mating and probably different mating rituals.

Retrieve your plant specimens. If you have an Edmentum lab kit, your specimens are a cork section, Zea
Tcecarenko [31]

In the plant, when a cell divides into two daughter cells, we observe in this experiment Mitosis, which is the cell division that allows the plant to elongate and occurs in the meristematic tissues that are at the ends of the plants. Whereas meiosis is restricted to reproductive tissue and forms gametes that will form new seeds through fertilization, carrying genes from one generation to another.

<h3>How does mitosis occur in plant cells?</h3>

In plant cells, division takes place from the inside out – centripetal cytokinesis. In plant cells, cytokinesis is centrifugal, from the outside to the inside: there is the formation of a lamella, which grows from the center to the periphery and separates the two cells.

With this information, we can conclude that through successive mitotic divisions that the zygote (cell generated after the meeting of gametes) manages to originate all the cells of its organism. Mitosis, therefore, is responsible for the growth and development of embryos.
