How are DNA and proteins related
Answer: Carry out these functions, DNA sequences must be converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodies. Each DNA sequence that contains instructions to make a protein is known as a gene
Answer:
The significance of DNA is very high. The gene's sequence is like a language that instructs cells to manufacture a particular protein. An intermediate language, encoded in the sequence of Ribonucleic Acid (RNA), translates a gene's message into a protein's amino acid sequence. It is the protein that determines the trait.

why do food chains in an ecosystem rarely contain more then five organisms
Why do food chains in an ecosystem rarely contain more than five organisms? ... Nutrients are lost from the ecosystem when organisms die. The conversion of food into growth by an organism is not very efficient. Energy is recycled by the decomposers back to the producers.
Abiotic factors of an ecosystem can include ?
Answer:
Abiotic factors are the non-living parts of the environment that can often have a major influence on living organisms. Abiotic factors include water, sunlight, oxygen, soil and temperature.
In the human body, is every organ a part of only one organ system? Or are some organs a part of two or more organ systems? A. Every organ is a part of only one organ system, which is necessary because organ systems work independently of one another. B. Every organ is a part of only one organ system, although organ systems often interact with one another. C. Some organs are a part of two or more organ systems. For example, the heart is a part of the circulatory and digestive systems. D.
C
[From ck12.org] "An organ can be part of more than one organ system. For example, the ovaries produce hormones, which makes them a part of the endocrine system; the ovaries also make eggs, which makes them a part of the reproductive system as well."
How does the Gulf Stream affect weather in the United States? A. It brings cooler temperatures from the poles. B. It brings cooler temperatures from the tropics. C. The warm surface currents help create storms and fog. D. The cool surface currents produce cooler weather and fog.
Answer: C. The warm surface currents help create storms and fog.
Explanation:
The gulf stream can be defined as strong ocean currents that brings about the warm wind currents from the oceanic water of the gulf of Mexico to the eastern coastal areas of the United States. These wind currents bring warm weather conditions in the United States. The strong wind currents can also cause storms and fog in the coastal areas of the United States.

Which process occurs within the mitochondria?
lactic acid fermentation
alcohol fermentation
glycolysis
Krebs cycle
The correct answer is D i.e. krebs cycle occurs in mitochondria.
what is mitochondria?
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP)
what is krebs cycle?
The tricarboxylic acid (TCA) cycle, also known as the Krebs or citric acid cycle, is the main source of energy for cells and an important part of aerobic respiration. The cycle harnesses the available chemical energy of acetyl coenzyme A (acetyl CoA) into the reducing power of nicotinamide adenine dinucleotide (NADH).
it is a closed cycle which produce 8 intermediates which are;-

The Gulf Stream is a surface current in the Atlantic Ocean that flows northward from the Caribbean Sea and the Gulf of Mexico. It feeds another current that reaches northern Europe. Which of these events would cause the greatest changes to the path and strength of the Gulf Stream?(please help)
A. a strong earthquake that occurs on the floor of the Atlantic Ocean
B. an increase in the volume of river water that flows into the Gulf of Mexico
C. a reversal of direction in the prevailing winds over the Atlantic Ocean
D. a slight increase in the salinity of the Atlantic Ocean
Answer:
It constitutes the northeastward extension of the Gulf Stream; the latter issues from the Gulf of Mexico and gradually emerges as the North Atlantic Current in mid-ocean. It is composed of several broad currents with speeds of about 0.2 knots, as compared with the Gulf Stream's rather concentrated flow at 1 to 6 knots.

Answer:
B. an increase in the volume of river water that flows into the Gulf of Mexico
How does the Golgi Body and Plasma membrane work together ?
Answer/Explanation:
The Golgi body is a system of flattened sacs that is involved in the packaging, modification, and transport of proteins. It is particularly important for proteins that have to be transported outside of the cell.
Proteins from the Golgi that are to leave the cell are transported in vesicles. When they reach the membrane, the vesicles fuse with it and release the proteins outside of the cell
