Which of the following units are repeatedly joined together to form a strand of DNA?
Answer:
Nucleotides
Explanation:
The nucleotides forming each DNA strand are connected by noncovalent bonds called hydrogen bonds.
Nucleotide is the unit that repeatedly joined together to form a strand of DNA.
What is DNA?Deoxyribose + phosphate group + thymine could be a nucleotide of DNA and defined as deoxyribonuclic acid and it is a polymer made up of two polynucleotide chains that arranged in foiled structure to form a double helix carrying genetic information for the various processes such as growth development functioning and reproduction.
There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.
Friedrich miescher discovered DNA in the year of 1860.The shape of DNA is double helical structure
The main function of DNA is to carry information from one generation to another generation this is the reason due to which DNA is also known information molecule.
In our body DNA is found in the nucleus of the cell and it is known as nuclear DNA. The shape of DNA is double helical structure.
Siblings share only about 50% of same DNA due to the reason of recombination. The life span of DNA is 521 years.
Therefore, Nucleotide is the unit that repeatedly joined together to form a strand of DNA.

place the following molecules in the order smallest to biggest
Answer:
NH₂⁻<NH₃<NH₄⁺
Explanation:
Hello.
In this case, regarding the molecules:
NH₄⁺, NH₃ and NH₂⁻.
Which are ammonium, ammonia and amide, in order to rank them in terms of how big the angles are, we need their molecular geometry as shown on the attached picture. As you can see, the geometry of ammonium is tetrahedral with an angle between H bonds of 109.5°, the geometry of ammonia is trigonal pyramidal with an angle between H bonds of about 107° and the geometry of amide is bent with angles of 104.5°.
Therefore the order from smallest to biggest is: NH₂⁻<NH₃<NH₄⁺.

a group of students found the specific gravity of a pice of galena to be 7.8. The accepted value for the specific gravity of galena is 7.2 find the % of error in the student's work
Answer:
Percent error = 8.3%
Explanation:
Given data:
Accepted value of specific gravity = 7.2
Measured value of specific gravity = 7.8
Percent error = ?
Solution:
Percent error = measured value - accepted value / accepted value × 100
Now we will put the values in formula.
Percent error = 7.8 - 7.2/7.2 × 100
Percent error = 0.6/7.2 × 100
Percent error = 0.083 × 100
Percent error = 8.3%

What is the Connective tissue?
What is the Epithelial tissue?
What is the Muscle tissue?
What is the Nervous tissue?
Answer:
connective: Tissue that supports, protects, and gives structure to other tissues and organs in the body
epithelial: are widespread throughout the body. They form the covering of all body surfaces, line body cavities and hollow organs, and are the major tissue in glands.
muscle: Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts. The tissue is highly cellular and is well supplied with blood vessels.
nervous: Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.
Explanation:
Answer
Connective tissues gives support, protects and gives structure to other tissues and organs in the body.... example bone, cartilage, blood etc.
Epithelial tissues are spread throughout the body. Their functions include secretion (sweat, mucus), absorption (nutrients) and protection (tissues that lie beneath from radiation) in the body.
Muscle tissue is composed of cells that have the special ability to shorten or contract in order to produce movement of the body parts.
Nervous tissue is found in the brain, spinal cord, and nerves. It is responsible for coordinating and controlling many body activities.

Prevailing winds blow from the Pacific Ocean toward two cities separated by mountains. City A is on the leeward side of
the mountains and city B is on the windward side. Which city is likely to have a wetter climate? Explain your answer.
Answer:
City B will have a wetter climate.
Explanation:
This is because in windier areas in tends to get more wet than rocky areas (mountains) where City A lies. Also because more wind will blow more and more clouds in the direction of city B making it rainier there a lot more often than a non windy rocky are.

You are asked to study a new inhibitor of oxidative phosphorylation. When it is added to a suspension of mitochondria carrying out this process, both ATP synthesis and oxygen consumption are inhibited. You suspect that the inhibitor blocks either the F-type ATPase or the electron transport chain. You can perform an experiment that measures the consumption of oxygen and the synthesis of ATP by isolated mitochondria. In one paragraph (6 sentences maximum), explain how the uncoupler, dinitrophenol, can be used to determine whether the inhibitor blocks the ATPase or the electron transport chain.
This was all the information that was given.
Answer:
DNP produces the loss of the proton gradient (i.e., the energy of the proton gradient is dissipated in the form of heat instead to produce ATP)
Explanation:
2,4-Dinitrophenol (DNP) acts to shuttle H+ ions across cellular membranes, bypassing the ATP synthase used by mitochondria to generate ATP during cellular respiration. Since DNP is able to bypass ATP synthase, this compound uncouples the phosphorylation of ADP by the ATP synthase from the process of oxidation (i.e., transport of electrons). For example, in muscle cells, DNP may be used to shuttle calcium ions (Ca +) from mitochondrial stores, and free intracellular Ca+ ions are evidenced to produce muscle contraction.
Francine is developing a model of the carbon cycle, which involves the movement of carbon among various Earth systems. She begins by drawing the diagram shown below. Her friend Byron evaluates the model, and suggests that she thicken the arrow leading from fossil fuels to the atmosphere. His reasoning is that fossil fuels are being burned at a much faster rate than natural processes are restoring them. If Francine adopts Byron’s suggestion, how could her model be used to explain a significant change to Earth's systems?
Answer:
After adopting the suggestions of Byron the new or revised model would show that using fossil fuels at a rapid rate would lead to higher inputs of carbon dioxide to the atmosphere which will not be removed by the natural process of removing the excess amount of the carbon dioxide by the process of the photosynthesis and other.
The carbon dioxide would increase due to this and cause trapping of the solar heat in the atmosphere which leads to the greenhouse effect to warm the earth. That ultimately changes the climate of the earth.
The process of removing wastes from the cell is known as
A.) endocytosis
B.)exocytosis
C.) pump

Looking at the following organisms and their diets, place them into a food chain. Make sure you have arrows that show the correct flow of energy.
Aardvark: omnivore diet
Ant: herbivore diet
Grass: autotroph
Hyena: carnivore diet
Answer:
Grass > Ant > Aardvark > Hyena
Explanation:
The grass is autotrophic, which means it can produce its own food It does so using water, carbon dioxide, and light energy from the sun. The organisms in this food chain rely on other organisms for food.
The ant is a herbivore that consumes the grass for energy. The aardvark consumes both plants and animals (omnivore), so it can consume the ants. The hyena is a carnivore, meaning it only eats animals, such as the aardvark.
