Why did Gregor Mendel choose to use purebred plants in his experiments?

Answers

Answer 1

Answer: Gregor Mendel is a Central European Monk who studied genetics through plants. He is greatly known as the founder of modern science genetics. In his various experiments, Mendel cross-pollinated pea plants because the peas have characteristics that have two forms. This means that pea plants have both male and female reproductive systems. They have the capacity to self-pollinate or cross-pollinate with other plants and as a result, Mendel discovered the nature of genetic inheritance.

At that time, Mendel debunked the famous “blending theory” commonly believed by scientists. This is a theory in biology where scientists believed that through time traits of organisms blend from generation to generation to create new organisms.

D. involves variations in temperature.

Answers

Unlike weather, climate describes the average conditions and atmospheric patterns of a region over a period of time. Weather is the day-to-day atmospheric conditions. It includes windy days, sunny, rainy, cloudy and etc. Weather then describes the state of an atmosphere at a place and time to its heat, dryness, sunshine, wind, rain. Climate on the other hand is the prevailing conditions of an area over a period of time, for instance, tropical climate.

It is climate (A) that describes the average conditions and atmospheric patterns of a region upon the Earth, over a period of time. It is distinctive from the weather which describes the specific meteological activity taking place at a specific time and in a specifc location upon the Earth.

How many planes of symettry can you draw through a jelly fish?A-None
B-2-5
C-1
D-More than 5

Answers

I believe that the answer is B.) 2 - 5.

My reason being is because symmetry basically means 3-D , So you are asking how many sides can you see when looking through a jelly fish.

When looking through any jelly fish you will see 2-5 sides , 2-5 because there are four ( 4 ) , There is the front , the back and also both sides so it's four ( 4 ).

That was my reason for the answer I chose.

It would be D but you will not see at lease 5 sides to a jelly fish , why? = because they don't have 5 sides , most of them are square shaped or circular.

I really hope that this helped you out a lot.
