Which of the following is the best definition for the term "evolution"?
Group of answer choices
A change in the frequency of genes in a population over time
A measure of the successfulness of the most fit creatures in a population
A measure of the change of a specific trait in an individual over time
A change in the shape of an individual or group over time
A change in the abilities of the strongest creatures in a population
Answer:
it is option c
Explanation:
In biology, evolution is the change in the characteristics of a species over several generations and relies on the process of natural selection.
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
1 and 3
1 and 4
1, 2, and 4

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
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.
Therefore, the correct options are A, C and E.
Distinguish between gaseous exchange and respiration
Answer:
Respiration is the process in which food is oxidized to release energy. Complex organic compounds are converted into simpler ones, e.g glucose into CO2 water and energy released. Gaseous exchange is the diffusion of gases from a region of higher concentration to a region of lower one.
Explanation:
Breathing is the physical process by which air is passed on a gaseous exchange surface i.e. ventilation of the gaseous exchange surface. It involves Inhalation and Exhalation.
Gas/Gaseous exchange is the process whereby gasses diffuse across a gaseous exchange surface. In humans, oxygen diffuses from the inhaled air into the blood and carbon dioxide diffuses from the blood into the exhaled air. The gaseous exchange surface here being the Alveoli.
Respiration is the metabolic process whereby organic molecules are broken down to release energy in the cells. In humans, this process takes place inside the mitochondria of cells. Aerobic respiration requires oxygen whereas qnqerobic respiration takes place in absence of oxygen.

Matthias Schleiden and Theodor Schwann made which contribution to science?
A. Discovered that new organisms do not spontaneously arrive in suitable conditions, but must be brought there.
B. Discovered the process plants use for energy, photosynthesis.
C. Discovered a basic principle of chemistry, that all matter is composed of atoms.
D. Discovered a basic principle of biology, that all plants and animals are made of cells.
Matthias Schleiden and Theodor Schwann made a significant contribution to science as they discovered a basic principle of biology, that all plants and animals are made of cells. So the correct option is option D.
Matthias Schleiden and Theodor Schwann made the contribution of discovering a fundamental principle in biology known as the cell theory. In the 1830s, they independently proposed that all plants and animals are composed of cells. Their work laid the foundation for our understanding of the structural and functional units of life. Together, the contributions of Schleiden and Schwann formed the basis of the cell theory, The correct option is option D.

What form is DNA in during mitosis?
A. protein
B. ribosome
C. chromatin
D. chromosomes
Answer:
Chromosomes form is DNA in during mitosis.
Explanation:
In the context of the cell cycle, mitosis is the part of the division process in which the DNA of the cell's nucleus is split into two equal sets of chromosomes.
During mitosis, DNA is in the form of chromosomes, which is option D, as the chromosomes are condensed and highly coiled structures made up of DNA and associated proteins called histones.
During mitosis, a cell divides into two daughter cells that are genetically identical to the parent cell. Chromosomes are critical to this process because they carry the genetic information necessary for the formation of the new cells, and before mitosis begins, the chromatin (a complex of DNA and proteins) in the nucleus of the cell condenses into visible chromosomes. This condensation process involves the compaction of chromatin into a more compact and organized structure.

¿Qué tipo de célula apareció primero en la Tierra?:___, y se presentan en seres vivos como las:___ y se caracterizan porque:___. *
Answer:
Célula procariota y procariotas.
Explicación:
La célula procariota es un tipo de célula que apareció por primera vez en la Tierra hace unos mil millones de años. Estos tipos de células están presentes en los procariotas, lo que significa que estos organismos no tienen un núcleo verdadero o una membrana nuclear alrededor del núcleo y otros orgánulos de la célula. El ADN del organismo procariótico se encuentra en una parte central de la célula que se conoce como nucleoide. La pared celular de un procariota actúa como una capa adicional de protección, ayuda a mantener la forma y estructura celular y previene la deshidratación.
