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.

Explanation:
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.

Which process produces four genetically different gamete cells?
A. Mitosis
B. Meiosis
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.
Meiosis produces somatic cells like egg and sperm cells.
A. True
B. False
Answer:
true
this statement is true
Answer:
B. False
Explanation:
Meiosis produces gametes like egg and sperm cells.

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.

Samuel has a block of modeling clay, three heavy blocks, and a hot plate covered by a tray as shown. How could he use these items to model the process of an existing rock becoming a metamorphic rock, according to the rock cycle, and to model the flow of energy that drives this process?
Answer:
Block of modeling clay is placed under three heavy blocks, and a hot plate covered by a tray.
Explanation:
Block of modeling clay is placed under three heavy blocks, and a hot plate covered by a tray is used for forming a metamorphic rock. Metamorphic rocks are formed when the rocks are placed to high heat, high pressure, hot mineral-rich fluids or combination of all these three factors. Conditions like these are found deep within the Earth so by placing block of modeling clay is placed under three heavy blocks, and a hot plate covered by a tray formed metamorphic rock.
¿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.
