Answer:
Ever since the existence of life of humans on Earth, the humans have been making progress to understand themselves and the mother nature.
In the start, the humans were hunter- gatherers. Hunter- gatherers can be described as humans which use wild life plants and animals for food. The humans used to live in jungles and eat the wild- life plants and animals. They used leaves from the trees to cover their bodies. Heat was produced by rubbing the rocks.
After this time, the humans learned the techniques of cultivating plants for food. They started cultivating crops and depend on them for living. During this time, humans learned the art of farming and agriculture. But they couldn't understand the effects of various pathogens infecting the crops and humans at that time.
After this time, humans learned the art of preserving foods in different forms like pickles etc. They also learned that certain types of plants could be used to treat wounds and other diseases.
With the passage of time, people learned to make and use machinery for making their tasks easier. The usage of machinery progressed rapidly and the industrial revolution began. People became more diverted to this sector rather than farming. They started to move towards the cities to find better jobs in industries.
Life after industrial revolution was much easier as humans had made a lot of equipments which aid them to have a better life style. Science has been developing since that time day by day.
Explanation:
The age of oceanic bedrock on either side of a mid-ocean ridge is supporting evidence that at the ridges, tectonic plates are Diverging
.
Explanation:
The underwater mountain range is the mid oceanic ridge, which were formed as a result of plate tectonics. when the convection current goes up in the mantle present beneath the oceanic crust results in the uplifting of the ocean floor.
Which leads to the formation of the tectonic plates through magma, that meet at divergent boundaries. The density and the age and the thickness of these oceanic crust increases due to the distance from the ridges. The mid oceanic ridges has been split on two sides as matching stripes

Answer:
Meiosis
Explanation:
Because meiosis is a reduction division
Answer:
A: can be subject to environmental conditions.
Explanation:
Phenotype is a genetics term used to describe an individual's observable characteristics that result from interactions with the genotype and nonheritable environmental factors.
Phenotypes are the <u>manifested</u> <u>aspects</u> of the morphology, physiology, biochemical properties, behavior and ecological relationships of an organism.
Given these statements, it can be concluded that two organisms cannot have the same phenotype (not even twins), because there will always be, however small, a morphological or physiological difference between them.
