What is the average lifespan of algae?

Glucose is used by plants to synthesize cellulose, the structural material in plant cell walls, which does not occur in animals as they cannot produce cellulose.

One use for glucose in plants that does not occur in animals is in the synthesis of cellulose, which is the structural material of a plant's cell walls. Animals, including humans, are unable to synthesize cellulose because they lack the necessary enzymes to form the beta-glycosidic linkages that characterize this polysaccharide. Cellulose gives plants their rigid structure, allowing them to stand upright and form the necessary frameworks for leaves, stems, and roots. In contrast, animals must obtain cellulose indirectly by eating plants or plant products, and most cannot digest it, using it mainly for fiber.

Mitosis produces two genetically identical daughter cells from one parent cell. This cell division process involves multiple stages to ensure accurate genetic replication and distribution. The resulting two cells are vital for growth and repair in organisms.

Mitosis is a process of cell division that results in two genetically identical daughter cells from a single parent cell. During this process, the nucleus divides, ensuring that each daughter cell inherits an exact copy of the parent cell's chromosomes. Hence, in mitosis, you start with one cell and end up with two cells, each with a complete set of genetic material.

Stages of Mitosis

The process is divided into several stages: prophase, metaphase, anaphase, and telophase, followed by cytokinesis. By the end of telophase and cytokinesis, the original cell has divided into two identical cells.

These two newly formed cells are crucial for growth, healing, and various other functions in multicellular organisms. Each of these cells maintains the same number of chromosomes as the parent cell, ensuring genetic consistency.

Answer:

I belive that it is that a virus in nonliving but I'm like 99% sure

Explanation:

Once a person gets a viral infection, the infection can best be treated with antibiotics.

Antibiotics are used to treat or prevent some types of bacterial infections. They are not effective against viral infections, such as the common cold or flu. Antibiotics should only be prescribed to treat health problems: that are not serious but are unlikely to clear up without antibiotics – such as acne.

They are very helpful in fighting disease, but sometimes antibiotics can actually be harmful. Key facts to know about antibiotic safety: Antibiotics can have side effects including allergic reactions and serious, possibly life-threatening diarrhea caused by the bacteria (germ) Clostridium.

Answer:

Theodor Schwann

Explanation:

A. The kinetic energy of moving water is converted to electrical energy.

The right answer is d. sugar molecules move outside of the membrane.

The simple diffusion is the diffusion through the plasma membrane (in the direction of the strong concentrations towards the weak concentrations, until equilibrium concentrations on both sides of the membrane). In the case that we have, the most concentrated compartment in glucose (that is inside the cell) will let it escape and go to the extracellular compartments until reaching equal concentrations between the two compartments.

Final answer:

CAM and C4 plants are trying to eliminate oxygen from the Calvin cycle.

Explanation:

CAM and C4 plants are trying to eliminate oxygen from the Calvin cycle.

CAM plants, such as cacti and succulents, close their stomata during the day to conserve water. At night, they take up CO2 and store it as organic acids, which are broken down during the day, releasing CO2 to enter the Calvin cycle.

C4 plants, like corn, have a unique leaf structure that allows them to keep their stomata open for CO2 capture while minimizing water loss. They use a specialized pathway to concentrate CO2 in bundle sheath cells, separating oxygen from the Calvin cycle and preventing photorespiration.

CAM and C4 plants are trying to eliminate oxygen from the Calvin cycle.

CAM and C4 plants are both trying to eliminate oxygen from the Calvin cycle.

In CAM plants, stomata are closed during the day to minimize water loss, but they open at night to take up CO2. The CO2 is fixed by combining it with PEP to produce malic acid, which is stored in vacuoles. During the day, the malic acid is converted back into pyruvate and CO2, which enters the chloroplasts and joins the Calvin cycle.

In C4 plants, CO2 is rapidly transferred from mesophyll to bundle sheath cells. In the bundle sheath cell chloroplasts, malic acid is oxidized to pyruvate, releasing CO2. This CO2 then enters the Calvin cycle for rapid fixation.

Answer:

The correct answer will be at elongation step of translation.

Explanation:

Translation is a process during which synthesis of proteins takes place inside a special organelle called ribosomes in cytoplasm or ER of the cell. It proceeds in three stages: Initiation, elongation and termination.

tRNA molecules are involved during elongation phase of the translation where they add amino acids to nascent protein chain.

tRNA gets charged with amino acids at its 3' end and becomes charged aminoacyl tRNAs which binds to A (aminoacyl) site of the ribosomes where it forms peptide bonds growing polypeptide chain. Then it binds to P (peptidyl) site of ribosomes where an initiation complex with free A site accepts tRNA after start codon chain elongation takes place. In last, they binds to E (exit) site of ribosomes where they gets dissociated from the ribosomes so that they can be recharged again with free amino acids.

Thus, during elongation phase they gets dissociated from the ribosomes.

The correct answer is:

cork bark

Explanation:

The cell was first discovered and described by Robert Hooke in 1665. He mentioned that it looked especially like cells or little rooms which friars occupied, in this way limiting the name. Nevertheless what Hooke really recognized as the dead cell dividers of plant cells (cork) as it bestowed up under the magnifying lens.

The expected outcome of crossing two tomato plants that are heterozygous for hairy stems is observing a phenotypic proportion of 3:1 plants (3 hair stem plants: 1 hairless stem plant).

Dominance in genetics is a phenomenon where the dominant alleles mask the recessive allele in heterozygous individuals.

In conclusion, the expected outcome of crossing two tomato plants that are heterozygous for hairy stems is observing a phenotypic proportion of 3:1 plants (3 hair stem plants: 1 hairless stem plants).

Answer:

The answer is The cell could not produce the energy necessary to carry out its metabolic processes and therefore would cause death.

Explanation:

Cellular respiration is a metabolic process by which cells reduce oxygen and produce energy and water. These reactions are indispensable for cell nutrition. The main objective of cellular respiration is to produce the energy that the cell needs to perform mechanical, chemical and transport work, that is, due to cellular respiration, the cell can obtain the energy necessary to perform all its metabolic functions.

Final answer:

Without cellular respiration, ATP production would cease, affecting all cellular functions. An absence of respiration would impede the breakdown of fatty acids and lead to increased CO₂ levels, disrupting the carbon cycle and threatening life. Glycolysis in red blood cells is crucial, and if hindered, it would affect their ability to transport oxygen.

Explanation:

If cellular respiration did not occur, several critical events would happen, leading to severe malfunction in biological systems. First and foremost, ATP production would cease, and since ATP is the energy currency of the cell used for nearly all biological processes, cells would not have the required energy to function properly. Moreover, substrates like pyruvate and citric acid, crucial for the energy production pathway, would not be produced, disrupting the metabolic cycle.

Without aerobic respiration, cells cannot burn fat for energy as fatty acids enter the pathway during the citric acid cycle, which requires oxygen. This would lead to an inability to utilize fat stores for energy, causing a significant impact on energy management and long-term energy reserves, which could result in the cessation of all functions that rely on fat as a fuel source.

Additionally, the absence of cellular respiration would lead to the failure of the detoxification of carbon dioxide, causing a buildup of  CO₂ which could be life-threatening. The relationship between photosynthesis and cellular respiration is vital for the planet's health. An absence would disrupt the carbon cycle, leading to increased levels of CO₂ and potentially suffocating breathing organisms.

Organisms incapable of aerobic respiration, like human red blood cells, which rely on glycolysis, would also suffer if glycolysis were hindered because they cannot tap into other sources of energy. This would impair their function, as they require a consistent supply of energy to maintain membrane integrity and transport oxygen throughout the body.

In summary, the absence of cellular respiration would be catastrophic for all aerobic organisms, leading to a lack of energy production and as a consequence, insufficient cellular function and, ultimately, the inability to sustain life.

In eukaryotes, the mitochondrion houses many enzymes necessary for the myriad of reactions that constitute cellular respiration. If these conditions are not maintained, such as the absence of oxygen, the process cannot occur efficiently leading to failed energy production.

During anaerobic respiration, less ATP is produced in the absence of oxygen, which is not enough to sustain human cells for an extended time. This occurs in muscle cells during intense exercise and is seen in yeast during beer brewing. This form of respiration is only a temporary solution during oxygen-deficient situations and is not a sustainable alternative to aerobic respiration.
