Answer: TRUE

Explanation:

The cell division that takes place during the growth and development of an organism is in an as MITOSIS. Mitosis takes place in somatic cells that is, body cells that are not involved in the production of gametes. The difference stages of mitosis were originally defined by cellular features observable through a LIGHT MICROSCOPE. These stages includes:

--> PROPHASE: when viewed under a light microscope, each chromosome shortens and thickens and is seen to consist of two chromatids. The Centriole begin to separate.

--> METAPHASE: The nuclear membrane disappears, a spindle forms, the chromosomes line up across the middle of the cell and become attached to the spindle fibres at their centromeres.

--> ANAPHASE: The sister chromatids are pulled apart to opposite ends of cell as the spindle fibres contract.

--> TELOPHASE: A nuclear membrane forms around each set of chromatids, and the cell divides into two daughter cells.

Why is the rate of movement of the air bubble not exactly the same as the rate of water loss from the plant?

OLEGan [10]

Answer:

Both depends on different factors.

Explanation:

The rate of movement of the air bubble is not exactly the same as the rate of water loss from the plant because both depends on different environmental factors. The higher rate of movement of the air bubble occurs due to removal of pressure while on the other hand, the rate of water loss from the plant occurs due to temperature. So both air bubble and transpiration process depends on different environmental factors.

The phenotype of an organism is its physical characteristics, which result from the organsism's genes.

FromTheMoon [43]

What is the question ??

The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.

Mountain ranges form along ___ plate boundaries via orogenic processes.

Tamiku [17]

1. Mountain ranges form along <u>convergent </u>plate boundaries via orogenic processes.

<h3>What is tectonic plates?</h3>

The formation of mountains is caused by tectonic plates. A mountain is formed when two tectonic plates move towards each other and collide, resulting in altitudes that can take years to reach but that eventually create massive mountains through what are known as convergent plate borders.

2. Rift valleys formed through the stretching of divergent plates occurs through a divergent boundary process.

When tectonic plates separate, they can leave low ground areas like the Rift Valley, which are produced by diverging continental plate borders. They can be found on the surface of the Earth or at the bottom of the ocean, and they are formed by the expansion of the seabed.

3. The formation of mountain ranges occurs as a result of <u>orogeny</u>.

This process occurs when one continental plate dips and the other rises, allowing mountain ranges to form. Orogeny is the name given to this process.

4. Scientists observe an extremely long <u>deformation </u>area in a continental plate during an orogenic process..

Scientists use tectonic plate simulations to study this deformation in order to better predict natural disasters such as earthquakes.

5. <u>Epeirogenic </u>process causes vertical plate motion along tectonic plates.

The vertical movement of a continent that generates soft arcs or rises parts uniformly is known as epeirogeny.
