Answer:A) UCAAGU

Explanation: Molecule 1 is a double-stranded DNA helix while molecule 2 is a single stranded RNA molecule.

DNA is copied into an RNA molecule in a process known as transcription. Transcription is catalyzed by RNA polymerase. During transcription, a DNA strand is used as a template for the synthesis of a complementary RNA strand. In base pairing, wherever adenine occurs in the DNA template strand, uracil occurs in the complementary RNA strand, wherever thymine occurs in the DNA template strand, adenine is found in the complementary RNA strand while wherever guanine is found in the DNA template strand, cytosine occurs in the RNA strand.

Assume that a black guinea pig crossed with an albino guinea pig produced 5 black offspring. when the albino was crossed with a
Radda [10]
As a matter of terminology, albino guinea pig actually refers to a white fur guinea pig, whose genotype is homozygous recessive (bb).

If it crossed with a black fur guinea pig and gave 5 black fur offsprings, there is a good chance that the black fur parent is homozygous dominant (BB).
The Punnett square would be as follows:

       B      B
b     Bb   Bb
b     Bb   Bb
So they are all heterozygous black fur offsprings.

However, it is not impossible that the black fur parent be heterozygous, namely

       B      b
b    Bb   bb
b    Bb   bb

Giving a 50% chance on each colour.  Thus it is possible (with probability 1/32) that all five offsprings are heterozygous black fur if one of the parents was heterozygous.

In the second case, a homozygous recessive and a homozygous dominant parent will never give a white offspring.  So it is sure that the black fur parent is heterozygous, with the following Punnett square:

       B      b
b     Bb   bb
b     Bb   bb

With a 50% probability for each of Bb (black fur) and bb (white fur).
the distribution 4,3 demonstrates this perfectly.

2. In a classroom experiment, you ground up some spinach in distilled water and filtered the liquid onto a piece of filter paper
ivanzaharov [21]

Answer:

Mitochondria; cellular respiration.

Explanation:

A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.

A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.

Basically, mitochondria is one of the cell organelles found in all living organisms and it is known as the powerhouse. Therefore, mitochondria provides all the energy required in the cell by transforming energy forms through series of chemical reactions; breaking down of glucose into Adenosine Triphosphate (ATP) used for providing energy for cellular activities in the body of living organisms.

In a classroom experiment, you ground up some spinach in distilled water and filtered the liquid onto a piece of filter paper. The isolated organelles absorbed carbon dioxide and released oxygen. Thus, the cellular organelle which was most likely on the filter paper is mitochondria and the process it was performing is called cellular respiration.

Cellular respiration can be defined as a series of metabolic reactions that typically occur in cells so as to produce energy in the form of adenosine triphosphate (ATP). During cellular respiration, high energy intermediates are created that can then be oxidized to make adenosine triphosphate (ATP).

Basically, oxygen goes into the body of a living organism such as plants, humans and animals when they breathe while glucose is absorbed by the body when they eat.

max2010maxim [7]

Answer: Creating products, such as ethanol and enzymes.

Making drugs, such as antibiotics and vaccines.

Making biogas, such as methane.

Cleaning up oil spills and toxic wastes. Bacteria have long been used by humans to create food products such as cheese, yoghurt, pickles, soy sauce and vinegar. We are also able to use bacteria to break down our sewage and to clean up oil spills.
