Which evidence supports the idea that life on Earth has continually evolved
Answer:
Fossils are the remains of long-dead organisms, preserved in rock. Because rocks are laid down in layers, one on top of the other, the fossil record is generally set out in date order: the oldest fossils are at the bottom. Running through the fossil record makes it clear that life has changed over time.

There are two processes used by viruses to replicate: the lytic cycle and lysogenic cycle. Some viruses reproduce using both methods, while others only use the lytic cycle. In the lytic cycle, the virus attaches to the host cell and injects its DNA.
Genetically modified (GM) crops are foods that have had their genomes modified, allowing humans to increase the production of certain crops. Farmer A purchases GM seeds that are immune to a specific herbicide. She plants these seeds in rows over seventeen acres. The following spring, Farmer A's neighbor, Farmer B, tells her that nearly a third of the plants in his crop fields have the same immunity.
Which of the following describes the most likely explanation for this occurrence?
a.Rabbits which frequent both fields carried the seeds across to Farmer B's land.
b.Farmer A's crops cross-pollinated with Farmer B's crops on the neighboring land.
c.The two farms share an irrigation system which transmitted the immunity from one field to another.
d.By increasing the genetic diversity in Farmer A's crops, they have out-competed the crops on Farmer B's land.
Answer:
B.Farmer A's crops cross-pollinated with Farmer B's crops on the neighboring land.
Explanation:
Herbicide resistant genes may transferred to from Farmer A's plants to farmer B's plants via pollination. Option B is correct.
Jumping Gene:
It is a concept in biology which says that the genes present in the one plant can transfer to another plant via pollination. They are also known as Transportable elements.
Here Herbicide resistant genes transferred to from Farmer A's plants to farmer B's plants.

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
What do you think when you hear DNA? 13pts
Answer:
I think that DNA is like genetics, you share genetics (or you can call it DNA) with your family members, It's the genetic code that determines all the characteristics of a living thing. Basically, your DNA is what makes you, you! Each nucleotide contains a sugar and a phosphate molecule, which make up the 'backbone' of DNA, and, one of four organic bases.
Explanation:
What is energy? Give an example of how energy is used in a living organism.
Answer:
Energy, in physics, the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms. There are, moreover, heat and work—i.e., energy in the process of transfer from one body to another. Organisms use energy to survive, grow, respond to stimuli, reproduce, and for every type of biological process. The potential energy stored in molecules can be converted to chemical energy, which can ultimately be converted to kinetic energy, enabling an organism to move.
Explanation:
Energy is defined in the scientific community as the capacity to perform work.
What is Energy?Molecules need energy to be broken down, built up, and transported across plasma membranes.
Energy is required for all life's work. A significant amount of energy is also simply wasted as heat to the environment. The story of life is one of energy flow, including how it is captured, transformed, used for work, and lost as heat.
Because energy can never be regenerated (unlike matter), it is constantly needed by living things.
Therefore, Energy is defined in the scientific community as the capacity to perform work.

Which description distinguishes eukaryotes from prokaryotes
Answer:
Explanation:
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
Prokaryotes only contain a single circular chromosome and lack a nucleus and membrane-bound organelles. In contrast, eukaryotes have numerous linear chromosomes and a nucleus.
Organisms called eukaryotes have intricate cellular structures. Their cells are distinguished by the presence of a genuine nucleus, which contains the DNA that serves as the genetic code. The nuclear envelope, a double membrane that encloses the nucleus, is made up of numerous organelles including the Golgi apparatus, endoplasmic reticulum, and mitochondria. These organelles are in charge of carrying out numerous metabolic processes and carrying out specialised tasks required for the survival of the cell. On the other hand, prokaryotes are straightforward organisms devoid of a nucleus and organelles that are bound to membranes. Their cells have a single nucleoid, a circular fragment of DNA that floats freely in the cytoplasm and gives them some control over their genetic makeup.

which target organ releases glucose into the blood-stream as a result of the action of adreline?
a) adrenal gland
b) kidney
c) liver
d) pancreas
The answer for this is the liver
The target organ that releases glucose into the bloodstream as a result of the action of adrenaline is the liver, which is present in Option C, as the liver stores the glucose in the form of glycogen.
What is the importance of glycogen in the body?Glycogen is a polysaccharide that is stored in the liver and muscles of the human body and plays a crucial role in maintaining the body's energy as well as glucose homeostasis. During exercise or physical activity, glycogen is broken down into glucose, which is then released into the blood as fuel; this is regulated by hormones such as insulin and glucagon and prevents hyperglycemia.
Hence, the target organ that releases glucose into the bloodstream as a result of the action of adrenaline is the liver, which is present in Option C, as the liver stores the glucose in the form of glycogen.

A student kicks a soccer ball three times. Another student records the distance, the amount of time the ball travels, and the average speed in the table shown below. How many seconds did it take for the ball to travel 30 m during Kick 3?
F. 0.5 s
G. 1.0 s
H. 1.5 s
J. 2.0 s
Answer:
2/j
Explanation:
formula: average speed= total distance/total time
15=30/total time
30/15= 2
Hope this helped and good luck!!!
It would take 1 second for the ball to travel 30 m during Kick 3
SpeedSpeed is the ratio of total distance travelled to total time taken. It is measured in meters per second. The formula for speed is given by the equation:
Speed = distance / time
From the question, average speed = 30 m/s, hence:
Average speed = distance / time
30 = 30 / time
time = 1 second
It would take 1 second for the ball to travel 30 m during Kick 3.
