Farming the land has a decreasing effect on the overall amount of soil
erosion.
True or false ?
Answer:
False
Explanation:
Farming practices disturb the ground. Farmers remove native vegetation and then plow the land to plant new seeds. Tractor tires make deep grooves, which are natural pathways for water. Fine soil is blown away by wind.
Answer:
False.
Explanation:
Agriculture is perhaps the foremost vital activity that accelerates erosion due to the quantity of land that's farmed and the way abundant farming practices disturb the ground.

What is the acceleration of a 40 kg object pushed with a force of 400 N?
The acceleration of a 40 kg object pushed with a force of 400 N is 10 m/s.
How to find the acceleration of an object?Given:
mass =40 kg
acceleration = unknown
force = 400 N
By using the force formula, we get
f = ma
⇒ f/m=a
⇒(400)/(40) = 10 m/s
In line with Newton's second law of motion, the acceleration of an object equals the net force appearing on it divided via its mass or a = F m . This equation for acceleration may be used to calculate the acceleration of an item whilst its mass and the net force performing on it are known.

in a breed of dog, the breed for black fur is dominant and the gene for brown fur is recessive. Two dogs with black fur are bred. One of the offspring has brown fur. What is most likely the explanation for the brown fur?
1.) the dog received a mutated gene
2.) the dog only received one gene for fur color
3.) the dog received one gene for brown fur and one gene for black fur
Answer:
3) the dog received one gene for brown and one for black
The most likely reason for the brown fur in one of the offspring is that the dog received one gene for brown fur and one gene for black fur.
WHAT IS HETEROZYGOSITY?Heterozygosity is a genetic condition whereby a gene is made up of two different alleles.
According to this question, the breed for black fur (B) is dominant and the gene for brown fur (b) is recessive in the breed of dogs. If two dogs with black furs are crossed, one of the offspring has a brown fur.
The reason for the above observation is that the black-furred parents were both heterozygous i.e. Bb, hence, the dog received one gene for brown fur and one gene for black fur.

what is gene expression? What are the two stages of gene expression? What happens during those two stages?
Answer:
Gene expression is the process by which information stored in DNA is used to direct the synthesis of a specific gene product. This synthesis takes place in two stages: transcription and translation.
Explanation:
Gene expression is the process that makes it possible to obtain proteins from genes. Genes are nucleotide sequences of DNA that encode the information necessary for protein synthesis. This synthesis takes place in two stages: transcription and translation. Transcription takes place in the nucleus and in it one of the two strands that make up the double strand of DNA serves as a template for a specific sequence to be copied into a single stranded RNA molecule. Subsequently, this RNA leaves the nucleus and carries the message - the nucleotide sequence - to the ribosomes, hence the name of messenger RNA (mRNA). Translation is a cytoplasmic process in which the mRNA molecule is decoded to generate a specific chain of amino acids, called a polypeptide (the protein). The correspondence between nucleotides (mRNA) and amino acids (protein) is what is called the genetic code.
Explain how the changes in the trends for smoking may affect the occurrence of cardiovascular disease.
6 MARK QUESTION
Answer:
Smoking and cardiovascular disease
Smoking increases the risk of cardiovascular disease in several ways:
Smoking damages the lining of the arteries, including the coronary arteries. The damage encourages the build-up of fatty material in the arteries. This can lead to a heart attack or a stroke.
Inhalation of carbon monoxide in cigarette smoke reduces the amount of oxygen that can be carried by the blood.
The nicotine in cigarette smoke increases the heart rate, putting strain on the heart.
Chemicals in cigarette smoke increase the likelihood of the blood clotting, resulting in a heart attack or stroke.

Answer:
For the first box (top left one), it is AA
For the second box (top right one), it is Aa
For the third one (bottom left one), it is aA
For the fourth one (bottom right one), it is aa
This one above ^^^ is the top line of the punnet square (the small line)
A = free-hanging earlobes
a = attached earlobes
For the first box (top left one), it is free-hanging earlobes (both "A"s are dominants, and the dominant is greater than the recessive one).
For the second box (top right one), it is free-hanging earlobes (there is at least one dominant A so it will be greater than the other "a" although there is a chance for it to be an attached earlobe, but in this case, it isn't)
For the third one (bottom left one), it is free-hanging earlobes (again, there is at least one dominant A so it will be greater than the other "a" even though, there is a chance for it to be an attached earlobe, but in this case, it isn't)
For the fourth one (bottom right one), it is attached earlobes (both "a"s are recessive, there is not one dominant "a" which means that it will be an attached earlobe".
This one above is ^^^ is for the second line in the punnet square (the longest line) P.S you dont have to write the explanation you can just write if it's an attached earlobe or a free-hanging one
The ratio will be 75% to 25%. The 75% will be the offsprings inheriting the free-hanging earlobes, and the 25% will be the offsprings inheriting the attached earlobe. It is most likely that the offspring will inherit the trait for free-hanging earlobe since it is the dominant allele there is.

Explain in detail how the longer, more colorful tails evolved in peacocks despite causing disadvantages for the males.
Answer:
Due to mating
Explanation:
The longer and more colorful tails evolved in peacocks in the process of natural selection in order to preserve the peacock species despite causing disadvantages for the males.
The Long and colorful tails ensured that the females got attracted for mating and subsequent reproduction to ensure they didn’t go extinct.

\What did you have to do to turn an atom that is labeled “+ion or -ion” into a “Neutral Atom”?
Answer:if an atom is labeled as +ion then it needs electron to be neutral ,
but
if an atom is labeled as -ion then it has to lose electrons to be neutral.
Explanation:
A positive and negative ion can be converted to neutral by adding or deleting electrons respectively.
What is an Atom?It is the smallest particle that can represent an element. It is consist of electron, proton, and neutron.The electrons are negative particles and revolve around the nucleus. Protons are positive particles found inside the nucleus with neutrons. The number of positive and negative particles is equal inside a nucleus.A positive ion may lose one or more electrons and a negative ion may have one or more extra electrons.Therefore, a positive and negative ion can be converted to neutral by adding or deleting electrons respectively.

If an animal fossil was found in a rock, what would be the best way to determine its absolute age?
*analyze the rock’s mineral composition
*take X-rays of the fossil and surrounding rock
*compare it to similar-looking fossils that have already been dated
*measure the ratio of a radioactive isotope and its decay product present in the rocks around the fossil
Answer:
D
Explanation:
Absolute age is defined as the numeric age of fossils.
To identify the absolute age of a fossil, the amount of certain radioactive elements in the rock are measured. When fossils are formed in the rocks, a small amounts of radioactive elements is included in it. The process to identify age of fossil using radioactive elements is known radiometric dating. So, radioactive isotope and its decay product gives absolute age of fossils.
Hence, the correct answer is "D".

What do you conclude concerning whether viruses are alive? Is there a clear-cut distinction between living things and non-living things?
Answer:
yes
Explanation:
Viruses are considered non living by many scientists because they are not made of cells and they don't create their own energy. Instead they are proteins and genetic material that survive and replicate inside another form of life.
