Answer:
Feaces is a product of egestion. It is not directly formed from the major organs responsible for excretion (liver, kidneys, lungs and skin) and hence is not a result of metabolic reactions. That is why, feaces are not an excretory product.

Which process produces four genetically different gamete cells?
A. Mitosis
B. Meiosis
Answers
Answer:
Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.
Answer:
B. Meiosis
Explanation:
Specifically, meiosis creates new combinations of genetic material in each of the four daughter cells. These new combinations result from the exchange of DNA between paired chromosomes. Such exchange means that the gametes produced through meiosis exhibit an amazing range of genetic variation.
You have isolated two known bacteria with slightly different DNA patterns and have placed them in an environment with some unknown elements. After some time, you observe that cell No. 1 now has a different DNA pattern. Your goal is now to find out whether this new DNA was obtained by the cell from transformation or conjugation (and you know that it can only be from one of these two methods). Which of the following would be valid to investigate?
Test cell No. 1 for excised DNA that has been relocated
Test for foreign, similar DNA in the environment
Test for the presence of bacteriophages in the environment
Test for the presence of DNA patterns from cell No. 2 in cell No. 1

What makes up the inside or middle of the DNA ladder?
A. Sugar
B. Nucleotides
C. Nitrogen bases
D. Phosphate
Answers
Answer:
C. Nitrogen bases
Explanation:
It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. (Deoxyribose is the name of the sugar found in the backbone of DNA.) In between the two sides of this sugar-phosphate backbone are four nitrogenous bases: adenine (A), thymine (T), cytosine (C), and guanine (G).

The text describes several organelles in eukaryotic cells that seem to operate like bacterium. What relationship does this suggest between prokaryotes and eukaryotes? This suggests an endosymbiotic relationship between prokaryotes and eukaryotes caused eukaryotes to evolve from prokaryotes. Tell me how this evolution happened and what evidence supports this theory.
Answers
Answer:
Answer
Explanation:
Eukaryotes are the cells that make up our bodies, plants and animals and all cellular organisms that contain their genetic material in a nucleus, have a cytoskeleton and contain organelles, such as mitochondria or cytoplasts. Eukaryotes are thought to have evolved from prokaryotes. Bacteria and archaea are classified as prokaryotes, a group of simple, single-cell organisms. Prokaryotes usually contain a single, circular deoxyribonucleic acid, DNA, molecule and lack a nucleus and intracellular organelles.

What word is used to describe plant cells placed in a hypotonic solution?
Answers
Answer:
The answer is Plasmolysis
The word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.
What is a Hypotonic solution?A Hypotonic solution may be defined as a type of solution that significantly has osmotic pressure lower than that of another solution to which it is compared. This type of solution normally contains a lower amount of solute.
According to the context of this question, when a plant cell is placed in a hypotonic solution, water will flow through it by the process of osmosis from the solution into the plant cell. This leads to cause the cell to expand or swell. But as the cell wall of the plant is very rigid, it keeps the cell from bursting.
Therefore, the word that is used to describe plant cells placed in a hypotonic solution is known as Turgidity.

A student wants to know the effect a mutation might have on a species survival. The change causes a rabbit to have mottled brown fur. The student runs a computer simulation for ten generations.What possible conclusions can you draw
Answers
Answer: A. Evolution occurred because the allele frequency changed over time.
C. The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.
E. The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur
Explanation:
Based on the information given, the possible conclusion that can be drawn from the options given are:
A. Evolution occurred because the allele frequency changed over time.
C. The rabbits with mottled brown fur have a selective advantage that gives them more camouflage from predators.
E. The mutation had a positive effect, allowing those rabbits with the mottled brown fur to survive and reproduce better than those with the brown or white fur.
