Answer:
Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible. Only a small portion comes as visible light. Light is made of waves of different frequencies.

A soccer player kicks a ball. Which of the following describes the reaction force to this kick?
A. friction between the ball and the foot
B. friction between the ball and the ground
C. force applied to the ground by the foot
D. force applied to the foot by the ball
Answer: D. force applied to the foot by the ball.
Explanation:
The basic premise of force is that for every action, there is a reaction. The reaction force is the force that pushes back so to speak, against the action that you initiated.
This reaction force by acting against us, ensures that we move forward by pushing us.
When the player struck the ball, the ball pushed back against the player and this force that was applied to the foot by the ball was the reaction force.
What group is the first species to arrive in ecological succession?
A. Intermediate
B. Pioneer
C. Climax
Answer:
B. Pioneer
Explanation:
The first species to arrive are fast-growing “weedy species,” such as lichens or small annual plants, which create the first layers of soil as they decompose.
Answer:
B. Pioneer
Explanation:
The pioneer group is the first species to arrive in ecological succession. Hence, option (B) is the correct answer.

what do birds short necks help them to do? pls help :/
Explanation:
Most diving birds have (relatively) long necks and shorts legs, although their necks aren't as long as say herons, storks or egrets. Take the common loon for instance. Their necks can be up to half as long as their bodies but their legs are so short and set so far back that they are very awkward on land.
Answer: they can extend it out and twist their head around so easy

state how facilitated diffusion is achieved describe ways
Answer:
The polar membranes/ions go through the protein to bypass the hydrophobic tails, which are "afraid" of charged molecules.
Glucose passes through the protein because it's too big to diffuse on its own.

a rocket is fired straight upward from ground level with an initial velocity of 480Km)hr. After t second , its distance above the ground level is given by 480t-16t^2. For what time interval is the rocket more than 3200Km above ground level?
Answer:
answer
Explanation:
The rocket is 19.5 m above the ground when h=19h=19:

The rocket will then be at least 19.5 m above the ground for the interval 0.75≤t≤3.25
0.75≤t≤3.25
The time interval for which the rocket is more than 3200 km above the ground level is 61.25 seconds.
What is quadratic equation?To solve this problem, we need to find the time interval for which the rocket's distance above the ground level is greater than 3200 km.
We can start by setting the equation for the rocket's distance above the ground level equal to 3200:
We can then solve this equation for t using the quadratic formula
[tex]480t - 16t^2 = 3200\\t = (-480 +/- sqrt(480^2 - 4*(-16)*3200)) / (-32)\\This simplifies to:\\t = (-480 +/- sqrt(480^2 + 256000)) /\\ (-32)t = (-480 +/- sqrt(2304000)) /\\ (-32)t = (-480 +/- 1500) / (-32)t = (-1980) /\\(-32)t = 61.25t = -24.25\pi[/tex]
Since the time interval we are looking for is positive, we can ignore the negative solution. The time interval for which the rocket is more than 3200 km above the ground level is therefore 61.25 seconds.

Answer:
Order, Sensitivity and response to stimuli, Reproduction, Growth and developement, Regulation, Homeostasis. Hope that helps!
Reproduction is the process in making more of the same species. we won't get into that. Order is the food chain, and what the animal kingdom should cisist of. In sensitivity and response to stimuli, organisms respond to diverse stimuli. For example, plants can bend toward a source of light, climb on fences and walls, or respond to touch. Regulation is kinda like the ability to adapt. Animals come from all over, so they need to adapt to the climate, resources, and other animals around.

why do you produce carbon dioxide when working out?
Answer: The lungs bring oxygen into the body, to provide energy, and remove carbon dioxide, the waste product created when you produce energy. The heart pumps the oxygen to the muscles that are doing the exercise. When you exercise and your muscles work harder, your body uses more oxygen and produces more carbon dioxide.

1. Why are the chromosomes paired up?
Answer: Chromosome pairing refers to the lengthwise alignment of homologous chromosomes at the prophase stage of meiosis. ... For these organisms to produce cells with a single set of chromosomes, the sets have to be separated such that the daughter cells have one copy of each chromosome. The 22 pairs of homologous chromosomes contain the same genes but code for different traits in their allelic forms since one was inherited from the mother and one from the father. So humans have two homologous chromosome sets in each cell, meaning humans are diploid organisms.
