what is most likely the cause of the increase in carbon dioxide in our enviorment
Answer:
On Earth, human activities are changing the natural greenhouse. Over the last century the burning of fossil fuels like coal and oil has increased the concentration of atmospheric carbon dioxide (CO2). This happens because the coal or oil burning process combines carbon with oxygen in the air to make CO2.
Answer: Carbon dioxide concentrations are rising mostly because of the fossil fuels that people are burning for energy. ... From 1850 to 2018, 440 ± 20 Pg C (1 Pg C = 10¹⁵ g C) were emitted as CO₂ from fossil fuel burning (Friedlingstein et al. 2019).

4. As the ribosome moves along the messenger RNA molecule,
A. lipids are created by the synthesis of glycerol.
B. amino acids are linked to create a polypeptide.
C. nucleotides are formed by translation.
D. complex carbohydrates are converted into monomers.
Answer:
B
Explanation:
The ribosome reads the codons in the RNA sequence and coded amino acids. These amino acids join with a peptide bond and form a polypeptide (protein). This protein can be used for many functions in the body.

What is a trace element of life?

Using the picture, which factor does NOT limit the barnacle population on the rock?
A. space, because there is a limited amount of room on the rock
B. parasitism, because the barnacles and rocks must exchange nutrients
C. predation, because the barnacles at the top of the rock get eaten by sea birds
D. water, because the barnacles can only live on rocks that are near the water
Answer:
A
Explanation:
I'm quite sure its a, might be wrong.
Because there is just a little amount of space on the rock, the number of barnacles there is unaffected. So, the correct option is A.
What are Barnacles?Because they are an arthropod species and members of the subclass Cirripedia mostly in Crustacea subphylum, barnacles are linked to crabs and lobsters. Often found in erosive environments, shallow and tidal seas are where barnacles prefer to live.
Cirri, or feather-like appendages, are used by barnacles to feed. The cirri scan the water for microscopic organisms as they quickly extend and retract through the aperture at the top of the barnacle. If they detect a potential threat, they swiftly retreat into their protective shells.
Few barnacle species are parasitic, and the majority of barnacle species are not harmful to other creatures. They protect the animal they feed on by filtering feeding food particles from the water.
Therefore, the correct option is A.

What is a habitable zone? O A. It's a zone where planets slow down their speed of rotation to capture more sunlight. O B. It's a zone in which all planets have oxygen in their atmospheres. OC. It's a zone that is the right distance from a star for liquid water to be possible. O D. It's a zone where the harmful UV rays of a star cannot reach a planet's atmosphere.
Answer: C. It's a zone that is the right distance from a star for liquid water to be possible.
Explanation:
The definition of “habitable zone” means the distance from a star at which liquid water exists. Habitable zones are known to be neither too hot nor too cold for life. An example is: If Earth were at the same distance Pluto is, then liquid water wouldn't exist, because it would freeze, and become ice. Now, if Earth was at the same distance Venus is, then liquid water wouldn't exist, because it would become too hot and dry, which means that any organism won't be able to survive in those circumstances.

What common tool does this shape remind you of ?
How many strands do you see?
Answer:
There are 2 strands. The shape if of a double helix, but it reminds me of a twisted ladder.
Explanation:
Hope this helps!
DNA (Deoxyribonucleic Acid) is a molecule that contains the genetic instructions for all known living things' development, operation, growth, and reproduction. Two strands that are twisted together to create a double helix make up the DNA molecule.
What are the two strands of DNA composed of ?The two strands of DNA are composed of nucleotides, which are the substance that gives DNA its structure. A sugar molecule, a phosphate group, and a nitrogenous base make up each nucleotide. Adenine (A), thymine (T), cytosine (C), and guanine (G) are the nitrogenous bases found in DNA.
In DNA, the nitrogenous bases form hydrogen bonds that hold the two strands together. Both adenine (A) and thymine (T) couple naturally with cytosine (C) and guanine (G), respectively. Complementary base pairing is the name given to this base pairing.
For DNA to serve as a carrier of genetic information, its double helix shape is necessary. The genetic code, which contains instructions for how living things develop, grow, and operate, is made up of the nucleotide sequence along the DNA strands.
The mechanism through which DNA duplicates itself, including the two strands of DNA, is also very important. The two DNA strands split apart during DNA replication, and each strand acts as a template for the creation of a new complimentary strand. This procedure guarantees that the genetic material present in the original cell is replicated exactly in each subsequent cell.

how does plant reproduce by air layering method explain?
Answer:
it happens when a low branch or stem touches the ground and takes root
Explanation:
It happens when a low branch or stem touches the ground and takes root.
What is Air layering?It is possible to propagate plants through air layering without a horticultural degree, expensive rooting hormones, or specialized equipment.
Even a beginner gardener can learn a few helpful tricks and achieve success. The simplest technique is to use seeds, although maturation might take months or even years. Furthermore, seedlings are not always identical to their parent plants.
By using layering propagation, new plants will be created that are genetically identical to their parents and inherit all of their traits.
Therefore, It happens when a low branch or stem touches the ground and takes root.
