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.

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.

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%

Answer:

Energy drives the cycling of matter within and between systems in aerobic and anaerobic conditions.

Explanation:

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.

Answer:

Photosynthesis and respiration are two ways organisms obtain glucose.

Explanation:

Photosynthesis – process in which autotrophs use energy from the sun to produce their own food.

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.

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.

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⁺.
