25. A student observed a cell under a microscope. She wanted to determine what type of cell she was observing. She drew a diagram of the cell and labeled the parts.
Below is her drawing.

Cell
Mitochondria
Nucles
Vecule
Cytoplam
What type of cell was she most likely observing and what evidence supports this claim?
O A plant cell because it has a cell wall.
A fungal cell because it has a vacuole.
O A plant cell because it has a vacuole.
O A fungal cell because it has no chloroplasts.
Answers
Answer:
A Comparison of Cells Commonly Seen in Lab
Bacteria: prokaryotic. Very small. No nucleus, no chloroplasts, no mitochondria. Do have a cell wall.
Plant cells: eukaryotic. Relatively large. Have a nucleus, have mitochondria, sometimes have chloroplasts. Have a large central vacuole and a cell wall.
Animal cells: eukaryotic. Relatively large. Have a nucleus and mitochondria. Never have chloroplasts. Lack a cell wall, and have no central vacuole.
...
This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis).
The central vacuole takes up most of the volume of the cell. It is transparent, but you can see where it's pressing the chloroplasts up against the cell wall, especially at the ends of the cell.
Like animal cells, the cytoplasm of this plant cell is bordered by a cell membrane. The membrane is so thin and transparent that you can't see it, but it is pressed against the inside of the cell wall.
This cell was alive and at 1000x magnification when it was photographed.

Biologists refer to the number of chromosomes with an "#n". For example, 1n for one copy of chromosomes and 2n for two copies. How else can this be expressed?
Answers
Answer:
haploid/diploid
Explanation:
The number of chromosomes can also be expressed as haploid or diploid, instead of 1n for one copy and 2n for two copies.
The haploid number of chromosomes also refers to a copy of the chromosomes or half of the genome of organisms while the diploid number of chromosomes refers to the double or complete set of chromosomes in the genome of organisms.
So, in other words: n = haploid and 2n - diploid.
Which of these is not an example of how substances move within cells?
Answers
Answer:
Diffusion
Explanation:
Diffusion is the process of transporting substances through the cell membrane. The cell membrane is semi permeable, which means it only allows certain substances to exit and enter the cell. Substances move from a high concentration to a lower concentration without the use of energy.
Cell cycle is not an example of how substances move within cells. Thus, option D is correct.
What is cell cycle?A cell cycle is a series of events that takes place in a cell as it grows and divides. The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage).
Cell cycle is responsible for growth of cell not for the any substance movement within cell. Thus, option D is correct.

Distinguish between breathing and respiration.
Answers
As stated above, breathing is the biological process of inhaling and exhaling of the gases between the cells and the environment. The mechanism of breathing involves various respiratory structures such as the windpipe, lungs and nose. Respiration, on the other hand, is a chemical process that takes place in the cell.
➜ Breathing:
The process of obtaining oxygen and releasing carbon dioxide is called breathing.It is a physical process.It takes place in the lungs.It utilises energy from the food.Respiration:
The process of releasing energy from food is called respiration.Heterotrophs are directly or indirectly dependent on autotrophs.It takes place in the lungs as well as in mitochondria.It releases energy from the oxidation of simple food.A plant that normally has relatively few, long internodes develops short and more frequent internodes.

En un cultivo de células vegetales se introdujo una mutación genética que produjo como consecuencia la incapacidad de estas células para polimerizar todo tipo de moléculas de glucosa. ¿Que consecuencias podrían haber para estas células?
Answers
Explanation:
Aun cuando los procesos de replicación del material genético son muy precisos, no son perfectos, por lo que pueden producirse errores que generan cambios. Una mutación es una variación espontánea o inducida del genoma, un cambio permanente y heredable en la secuencia del ADN, en nucleótidos, o bien en la disposición del ADN en el genoma.
Estos cambios o mutaciones se deben a alteraciones de la información genética. Las consecuencias dependen entonces del nivel de afectación: desde cambios en la secuencia nucleotídica, en los genes o los productos génicos, hasta en los tipos celulares involucrados.
Todos los seres vivos cuentan con sistemas de verificación y reparación de los procesos celulares. En el caso de la replicación del ADN existen sistemas de reparación específicos y bien coordinados, pero en ocasiones las lesiones del ADN que escapan a esta verificación serán las causantes de ocasionar mutaciones; por lo tanto, la efectividad de la lesión dependerá tanto de la tasa de división celular, como de la eficiencia de los mecanismos de reparación contra el aumento en las lesiones al ADN. Cuando ambos factores están incrementados, el resultado será una mayor generación de mutaciones o mutagénesis (y carcinogénesis).

Answer:
Y is transcription, and Z is translation
Explanation:
DNA to mRNA is the process of transcription (think how DNA and mRNA both have nitrogenous bases, so to get mRNA from DNA you have to transcript-a written or printed version of material originally presented in another medium- it). mRNA to protein is the process of translation (think how mRNA and proteins are made from different building blocks, mRNA being from nitrogenous bases and proteins from amino acids, so it must be translated). Therefore, Y is transcription, and Z is translation.

The noble gases in group 18 were some of the last natural elements to be discovered. Why do you think this is so?
Answers
Answer:
because they were extremely un-reactive. Being inert, they were difficult to isolate via chemical reactions, thus difficult to distinguish as separate elements
Explanation:
The noble gases of group 18 were the last to be discovered because they are highly unreactive or inert.
Noble gases refer to elements in group 18. These elements are renowned for being inert.
As a result of their inertness and because they are all gases, they are sometimes called "inert gases".
This chemical inertness made it difficult to discover these elements until lately. Many natural elements were discovered because they participate in chemical reactions. Hence, inert gases became the last natural elements to be discovered.

Your stomach pH is about 2. Would you expect starch
digestion to take place in the stomach?
Answers
Answer:
The correct answer would be - no or very less.
Explanation:
Digestion of the carbohydrates including starch begins within the mouth with the help of amylase into maltose. Most of the starch digestion takes place in the small intestine.
The significant digestion of starch does not take place in the stomach due to the acidity of the stomach as at low pH, amylase denatured or stay inactivated. Once the starch fragments reach the small intestines pancreatic amylase digest starch.

In an ecosystem, the statement which describes one way that a nonrenewable energy resource is obtained is that mountaintops are blown up to mine coal.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
