When it is winter in North America, it is summer in South America. Explain why this happens. Read the assignment carefully and make sure you answer each part of the question or questions. After you've written your response, go back and read it again to make sure your thoughts are clear.
Answer:
It is also important to remember that the seasons in South America are the reverse of that in the Northern Hemisphere, meaning that summer falls between December and February and winter between June and August.
The further north you are on the continent, the closer you are to the Equator (the country, of course, but also the Equator line). The temperature variations between the different months of the year are therefore smaller and smaller as you go up. In other words, each seasons of South America depends on its country.

why do plants grown with less light grow taller than the ones grown with light
Hormones released down the stem from the tip of the stem inhibit stem expansion when exposed to light. The hormones do not impede stem growth in the dark. Seeds growing in the dark rely on chemical energy stored in their cells (lipids, proteins, and carbohydrates) to fuel their growth.
Topic: March PhenomenonAnswer:
The light slows stem elongation by sending hormones down the stem from the tip of the stem.
Explanation:
Hormones do not slow stem elongation in the dark. Dark-grown seeds rely on the chemical energy stored within their cells (lipids, proteins, carbohydrates) to power their growth.

Gabriel is performing an experiment in which he is measuring the energy and work being done by a ball rolling down a hill. Which statement best describes Gabriel’s measurements?
They will remain constant.
They will both be recorded in joules.
They will both be recorded in hertz.
They will involve compressions.
Answer:Its A
Explanation:Edge
Gabriel is performing an experiment in which he is measuring the energy and work being done by a ball rolling down a hill. The statement they will both be recorded in joules is best describes Gabriel’s measurements. Correct Option is 2.
Energy and work are both physical quantities measured in joules (J) in the International System of Units (SI). In this experiment, Gabriel is measuring the energy and work associated with the ball rolling down a hill, and both measurements will be expressed in joules. Energy represents the capacity to do work, and work is the transfer of energy that occurs when a force is applied to move an object over a distance. Both energy and work are directly related and are measured in the same unit, joules, which is a measure of energy or work.
