Can a virus cause a change in your DNA?
Please answer this don’t just take the points please I need help
Answer:
Yes , when viruses infect us, they can embed small chunks of their genetic material in our DNA. Although infrequent, the incorporation of this material into the human genome has been occurring for millions of years. As a result of this ongoing process, viral genetic material comprises nearly 10 percent of the modern human genome. Over time, the vast majority of viral invaders populating our genome have mutated to the point that they no longer lead to active infections. But, as scientists funded by the National Institutes of Health have demonstrated, they are not entirely dormant.
Explanation:
Answer:
Viruses are continuously changing as a result of genetic selection. They undergo subtle genetic changes through mutation and major genetic changes through recombination. Mutation occurs when an error is incorporated in the viral genome. Recombination occurs when co infecting viruses exchange genetic information, creating a novel virus.
so i will say YES

BRAINLIEST?The duplicity theory of vision holds that a single receptor system cannot produce both high sensitivity and high resolution. What does this theory explain
Given what we know about the Duplicity theory, we can confirm that this theory attempts to explain the functions of the Rods and Cones present in the human eye.
The Duplicity theory of vision aims to provide insight as to the functions of the Rods and Cones in the human eye and how each of these contributes to our everyday vision. The theory also centers around the difference in activity between these two structures.

Which two structures engage to create a muscle contraction?.
Muscle contraction occurs when actin connects with myosin.
Muscle contraction occurs thanks to an action potential, which transmits a stimulus to the interior of the muscles.
For fiber tension to occur, the myosin head must bind with actin, slip, release, and then connect with another actin.This electrical signal allows the actin and myosin proteins to move, thereby generating contraction of the muscles.Therefore, we can conclude that myosin is a protein found in muscle fibers in order to bind to actin protein and cause muscle contraction.

Without land regulations to protect rainforests, and continues to be destroyed using slash and burn methods Which environmental impact of rainforest deforestation makes rainforest species less resilient to
change?
Increased fire and drought
Increased pollution
Displaced inbes
Habitat fragmentation
Answer:
Increased pollution is your answer!
Explanation:
Increased pollution is your answer because:
1. ⇒ Burning of mostly anything creats, and all the materials in the forest are one of those materials that will create smoke. And smoke is made out of carbon dioxide, and other poisonous gases that are very bad for our atmosphere.
2. ⇒ The damage from the fire will also cause a lot of damage to the trees and plants. That is very bad because trees are very important for our environment, in their leaves, they have a chemical called chlorophyll, this chlorophyll absorbs sunlight and turns it into oxygen. Not only sunlight is needed, there is also, water, nutrients needed.

Laws, theorie
Question 4 of 10
Newton's second law of motion states that the acceleration of an object
depends on the force exerted on it, divided by its mass. This law can be
summarized by the equation F = mx a.
Why is this a law and not a theory?
A. Newton's statement involves mathematics. A theory is a
description based on observations,
OB. Newton's statement describes the relationship between mass,
acceleration, and force. A law is an explanation of natural events.
O C. Newton's statement is supported by research. A theory is only an
educated guess
D. Newton's statement has been proved with scientific evidence. A
theory can change when new evidence is found that does not
support the theory
SUBMIT
The second law states that the acceleration of an object is dependent upon two variables - the net force acting upon the object and the mass of the object. The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object.

5 A prokaryotic cell is 5.0 um in length. A virus particle is 300 nm in length. How many times larger is the prokaryotic cell compared to the virus particle?
A 2
B 17
C 60
D 167
The prokaryotic cell is 17 times larger as compared to the virus particle.
Both values first need to be converted to the same unit.
5.0 um = 5.0 x [tex]10^-^6[/tex] m
300 nm = 3.0 x [tex]10^-^7[/tex] m
Dividing both values:
5.0 x [tex]10^-^6[/tex] m/3.0 x [tex]10^-^7[/tex] m
= 16.667
Hence, the prokaryotic cell is approximately 17 times bigger than the virus particle.
