Answer:
A
Explanation:
For a recessive gene to affect the child they must inherit two recessive alleles because if a dominant allele is inherited than the dominant trait will be the one that is expressed in the child. The only way to get two recessive alleles is to inherit one from both parents so the father must also carry the recessive allele. This means A must be the correct answer.
Where does energy first come into an ecosystem?
A producers make energy
B the sunlight provides energy to producers
C consumers obtain energy from animals
D scavengers obtain energy from dead plants
Answer:B. Sunlight provides energy to producers
Explanation: photoautotrophs (plants) produce energy from sunlight by photosynthesis. This is the only energy production based on an external source of energy. Plants, whether alive or dead, are consumed by heterotrophs - bacteria, fungi and animals. The nutrients and energy from dead heterotrophs (and some live ones) are recycled by both autotrophs and heterotrophs.

What is the formula for net force?
Answer:
FNet = F1 + F2 + F3….+ FN
Explanation:
Answer:
FNet = Fa + Fg.Explanation:
FN is the force acting on a body. When the body is at rest, the net force formula is given FNet = Fa + Fg.
Annie has a soccer ball and a kickball. She kicks each ball with the same force. The soccer ball accelerates at 3 m/s2, and the kickball accelerates at 5 m/s2.
Use Newton’s laws to describe why the kickball has a greater acceleration.
Answer:
Its easy just take that 3 and add up with the 5
Explanation:
Its easy just add
Answer:
My Response:
I think Newton's second law does the best to describe why the kickball has a greater acceleration than the soccer ball when kicked at the same force. That law states that the formula to find force is F=m*a and we can flip that around to find mass or acceleration. In this case, we know that a soccer ball has more mass than a kickball so the formula would be different for the two balls. So, even thought the force applied is the same, because the masses are different, the acceleration is going to be greater for the ball that has the least mass, the kickball.
Sample Response:
Based on Newton's second law, if the balls are kicked with the same force, the one with less mass will have a greater acceleration. Since the kickball accelerates more than the soccer ball, it has less mass.

How are electromagnets different from other magnets?
Answer:
Electromagnets are powered by electricity. Normal magnets are just magnetic.
Explanation:
Isn't it obvious?
Answer:
One difference is that an electromagnet requires a continuing supply of electricity to maintain the magnetic field while other magnets do not.

These two birds both chirp a song in the morning. Compare and contrast the two
waves properties (wavelength, amplitude, frequency). Finally determine which bird's
sound wave has more energy and why?
EM .
Include the following terms in your answer:
• Frequency
• Amplitude
• Long Wavelength
. Short Wavelength
• Higher energy
• Lower energy
Answer:
Sound wave that have more energy are louder and have more frequency, amplitude and short wavelength
Explanation:
That bird's sound wave has more energy which has higher frequency of sound. Due to its higher frequency of sound, the amplitude is also higher. That sound which have higher frequency has short wavelength and those sounds which has lower frequency and pitch has long wavelength. So we can say that sound wave that have more energy are louder and have more frequency, amplitude and short wavelength whereas sound wave that have lower energy are less louder and have less frequency, amplitude and long wavelength

by what method do the gases oxygen and carbon dioxide pass into or out of the bloodstream?
Answer:
DIFFUSION
Explanation:
The oxygen in inhaled air passes across the thin lining of the air sacs and into the blood vessels. This is known as diffusion. The oxygen in the blood is then carried around the body in the bloodstream, reaching every cell. When oxygen passes into the bloodstream, carbon dioxide leaves it.
Why is it important that the DNA is replicated during the S phase of interphase
Answer:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

Where does the energy for most ecosystems originate? How is this converted into the energy in food?
Answer:
Explanation:
"Energy is transferred between organisms in food webs from producers to consumers. The energy is used by organisms to carry out complex tasks. The vast majority of energy that exists in food webs originates from the sun and is converted (transformed) into chemical energy by the process of photosynthesis in plants."

Electrodes work with a sort of "echo" process, where they emit a tiny electrical pulse then receive a responding pulse from the heart
True or False?
Answer:
true
Explanation:
i looked in my book for this
Electrodes work with a sort of "echo" process, where they emit a tiny electrical pulse and then receive a responding pulse from the heart, and this is a true statement regarding the heart.
What is the heart's electrical signal?The heart has the SA node that autonomously originates the signal, and then the AV nodes receive that, and then the signals are transmitted to the ventricle and the heart contracts. In this process, the heart's electrical signal travels through the atrium and ventricle, and when the device measures the signal, the tiny electrical pulse is received by the device, which shows the electrical nature of the heart.
Hence, electrodes work with a sort of "echo" process, where they emit a tiny electrical pulse and then receive a responding pulse from the heart, and this is a true statement regarding the heart.
