which of these actions has contributed to the increase of greenhouse gases in the atmosphere?
A) Clearing forests
B) Excessive planting
C) Chopping wood
D) Watering crops
Answer:
A
Explanation:
Trees and other plants absorb carbon dioxide from the atmosphere as they grow. This is converted into carbon and stored in the plant's branches, leaves, trunks, roots and in the soil. Cutting down of trees without allowing them to regrow, the carbon stored is released to the atmosphere in form of carbon dioxide which contributes to as much as 30 percent of global greenhouse-gas emissions.

Conservation
A) The process of wearing down, becoming weaker
Degradation
B) Animals eating vegetation at a rate faster than it can grow back
Exploitation
C) Saving of a resource by managing how it is used
Overgrazing
D) Unfair and unequal treatment of people or use of resources
The process of wearing down a substance leads to degradation, and the process of eating vegetation by the animal at a faster rate is called overgrazing. Thus, the correct options are A. 2, B. 4, C. 1, and D. 3.
What is degradation?Degradation is the process of wearing down the substance by the action of air, water, etc. which leads to erosion and weakening resulting in the formation of smaller particles. Hence, A. 2 is correct.
When the animals eat vegetation at a higher rate than their production causes the loss of food and decreases the carrying capacity in the process called overgrazing. Hence, B. 4 is correct.
Conservation is the process of saving resources by their effective uses, and exploitation is the unequal and unfair treatment and use of the resources and organisms. Hence, C. 1, and D. 3 are correct.

Explain how observation, interpretation, and explanation are important to the study of science.
Answer:
Observation is essential in science. Scientists use observation to collect and record data, which enables them to construct and then test hypotheses and theories. Scientists observe in many ways – with their own senses or with tools such as microscopes, scanners or transmitters to extend their vision or hearing.

What is the difference between the attic and equator Environment
An attic environment is a hot and muggy place, with few fresh breezes coming in. Meanwhile, the equator is a very dry and low altitude location that has lots of fresh air and major wind currents constantly circulating through. This exchange of air allows for natural temperature regulation- warm air rises to the updrafts at equatorial latitudes and cold air sinks around Antarctica . At a higher latitude like the United States, there are fewer major winds like monsoons or cyclones to provide this necessary "push" for different atmospheric temperatures over time. With little variation in climate (weather) patterns, there is also less need for sweating as moisture evaporation cools down your skin (thermoregulation).

Which of the following statements best describes the relationship between genes and DNA?
A
Genes are regions in the DNA that code for important products, such as proteins.
B
Genes are made up of proteins, which provide instructions for making DNA.
C
Genes are made up of multiple protein-encoding DNA molecules.
Answer:
A
Explanation:
Genes are composed of DNA arranged on chromosomes. Some genes encode structural or regulatory RNAs. Other genes encode proteins. Replication copies DNA; transcription uses DNA to make complementary RNAs; translation uses mRNAs to make proteins
Relationship between Genes and deoxyribonucleic acid are that - Genes are created of Proteins, which give directions for creating deoxyribonucleic acid.
What is DNA?DNA stands for Deoxyribonucleic acid that may be a chemical compound composed of 2 polynucleotide chains that coil around one another to create a spiral carrying genetic directions for the event, functioning, growth and replica of all renowned organisms and plenty of viruses.
DNA is the hereditary material in humans and most different organisms. Nearly each cell in every person’s body has an equivalent deoxyribonucleic acid.
DNA was discovered by famous Scientist Watson and Crick in the year 1950.
Most deoxyribonucleic acid is found within the nucleus (where it's known as nuclear DNA), however a tiny low quantity of deoxyribonucleic acid can even be found within the mitochondria (where it's known as mitochondrial deoxyribonucleic acid or mtDNA).
The information in deoxyribonucleic acid is hold on as a code created of four chemical bases: Adenosine (A), Guanine (G), Cytosine (C), and Thiamine (T).
Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism.
DNA bases combine up with one another, A with T and C with G, to create units known as base pairs. Every base is additionally hooked up to a sugar molecule and a phosphate molecule.
Together, a base, sugar, and phosphate are known as a Nucleotides. Nucleotides are organized in 2 long strands that type a spiral known as a Double Helix .
The structure of the double helix is somewhat like a ladder, with the base pairs forming the ladder’s rungs and the sugar and phosphate molecules forming the vertical sidepieces of the ladder.
An important property of deoxyribonucleic acid is that it will replicate and create copies of itself. Every strand of deoxyribonucleic acid within the spiral will function as a pattern for duplicating the sequence of bases.
This is vital once because cells divide as a result of which every new cell must have a certain copy of the deoxyribonucleic acid within the previous cell
What is a gene?A Gene is the basic physical and purposeful unit of heredity created of deoxyribonucleic acid.
Some genes act as directions to create molecules known as proteins. However several genes don't code for proteins.
In humans, genes vary in size from a couple of hundred deoxyribonucleic acid bases to quite two million bases.
Gene is a basic unit of heredity and a sequence of nucleotides in deoxyribonucleic acid that encodes the synthesis of a factor product, either RNA or Proteins.
Genes will acquire mutations in their sequence, resulting in totally different variants, called alleles, within the population.
These alleles cypher slightly totally different variant of proteins that cause totally different composition traits.
Genes evolve because of action / survival of the fittest and genetic drift of the alleles.
An endeavor known as the Human order Project, that worked to see the sequence of the human order and determine the genes that it contains, calculable that humans have between 20,000 and 25,000 genes.

Compare a virus to a unicellular organism. (1 point)
O Viruses need energy, unicellular organisms do not need energy.
O Unicellular organisms have a cell membrane made from a lipid bilayer, viruses have a protein coat
O Viruses reproduce through asexual reproduction; unicellular organisms need a host cell,
O Neither unicellular organisms nor viruses respond to stimuli.
Answer:
differences : Viruses need energy while unicellular organisms donot need energy
Unicellular organism has cell membrane but virus has protein coat.
Unicellular organisms have a cell membrane that is made from a lipid bilayer whereas viruses have a protein coat which is called capsid. Unicellular organisms reproduce through asexual reproduction whereas virus need a host cell for their survival because virus use the cell engine to extract food for their survival so it is conclude that unicellular organisms have cell membrane but virus has protein coat.
