For example, the discovery of fossil palm tree stumps in Alaska and the unearthing of fossil alligator remains in the Arctic Circle suggested that the high latitudes were a tropical landscape 52 million years ago.

Answer:
Arctic Circle suggested that the high latitudes were a tropical landscape 52 million years ago.
Which of these is likely to happen in the absence of the troposphere?
A meteorite may strike Earth
Radio and satellite communications would stop
We may not experience storms, winds, and clouds
Cases of sunburns, skin, and eye problems may increase
The correct answer is: Option C
"We may not experience storms, winds and clouds"
In the planetary boundary layer is where the friction with the earth's surface influences the air flow. This is the lowest part of the troposphere. This troposphere region is where is formed the winds, storms and clouds. Most of the metereological phenomena we associate with the daily metereological weather occurs in the troposphere, that's why its existence to the world is very important.

Explanation:
Explain the factors that determine an object's kinetic energy.
Answer:
Kinetic energy is the energy of motion. An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. There are many forms of kinetic energy - vibrational (the energy due to vibrational motion), rotational (the energy due to rotational motion), and translational (the energy due to motion from one location to another). To keep matters simple, we will focus upon translational kinetic energy. The amount of translational kinetic energy (from here on, the phrase kinetic energy will refer to translational kinetic energy) that an object has depends upon two variables: the mass (m) of the object and the speed (v) of the object. The following equation is used to represent the kinetic energy (KE) of an object.
KE = 0.5 • m • v2
where m = mass of object
v = speed of object
This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed. That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a threefold increase in speed, the kinetic energy will increase by a factor of nine. And for a fourfold increase in speed, the kinetic energy will increase by a factor of sixteen. The kinetic energy is dependent upon the square of the speed. As it is often said, an equation is not merely a recipe for algebraic problem solving, but also a guide to thinking about the relationship between quantities.
Kinetic energy is a scalar quantity; it does not have a direction. Unlike velocity, acceleration, force, and momentum, the kinetic energy of an object is completely described by magnitude alone. Like work and potential energy, the standard metric unit of measurement for kinetic energy is the Joule. As might be implied by the above equation, 1 Joule is equivalent to 1 kg*(m/s)^2.

Answer:
Chemical digestion involves the breaking down of food with enzymes; mechanical digestion is breaking down food by chewing and tearing with teeth.
Mechanical digestion means breaking down food mechanically. By chewing and tearing with teeth, food breaks down into smaller parts and no enzymes are used. Chemical digestion means breaking down food in a chemical manner. This is achieved by secreting enzymes, which break down chemical bond between food molecules.
you can write that or
Mechanical digestion prepares food for chemical digestion. It involves the chewing and mixing food with saliva, churning of food in the stomach, segmentation of intestines rhythmic local constrictions of intestine, causes mixing improves absorption. On the other hand chemical digestion breaks down complex food molecules into chemical building blocks, enzymes secreted into alimentary canal lumen.

How is the 2nd law of motion different from the 1st law of motion?
(This is about Newton's laws btw)
Answer:
Newton's First Law states that an object with no net force acting on it remains at rest or moves with constant velocity in a straight line. Newton's Second Law states that the acceleration of an object is directly proportional to the net force on the object and inversely proportional to the mass of the object. His First Law of Motion states that an object in motion tends to stay in motion unless another force acts upon it. This law is sometimes confused with the principles in his second law of motion, which states the relationship among force, mass and acceleration.

Describe how an El Niño event affected weather, food production, water supply, or human health.
Answer:
El Niño is associated with death and disease, most of which result from weather-related disasters such as floods and droughts. In 1997 Central Ecuador and Peru suffered rainfall more than 10 times normal, which caused flooding, extensive erosion and mudslides with loss of lives, destruction of homes and food supplies.
Answer:
Severe drought and associated food insecurity, flooding, rains, and temperature rises due to El Niño are causing a wide range of health problems, including disease outbreaks, malnutrition, heat stress and respiratory diseases.

A student wanted to test how the mass of a paper airplane affected the distance it would fly. Paper clips were added before each test flight. As each paper clip was added, the plane was tested to determine how far it would fly.
What was the dependent (outcome) variable from this experiment?
The paper airplane design.
The number of paperclips.
The type of paper.
The distance the plane flies.
Answer:
The distance the plane flies.
Explanation:
This is the dependent (outcome) variable because it is changing depending on the number of paper clips that are added to the plane.
Answer:

Write a description that explains how the digestive, circulatory, and excretory systems WORK TOGETHER in order to deliver very important materials to the cells and dispose of waste products from the cells! Try to include as many details as possible - What is the blood carrying? Where is it going? How does it get there? What does it get rid of and how?
Answer:
At the end of each organ system you will need to make a summary of that ... So how does the food we eat eventually get to our cells in a small enough form ... The circulatory system is responsible for transporting blood with oxygen (O2) ... the digestive system to the cells in the body and remove waste products to be excreted.
