Why is mitosis important 3 reasons?
Expansion and development. Mitosis is the process by which an embryo develops after a gamete from meiosis has united with another gamete to form an embryo. Cell division is essential for organism development, tissue repair, healing and regeneration, and reproduction. Asexual reproduction is a form of reproduction in which the number of chromosomes or the fusion of gametes are not altered.
Multicellular creatures depend on mitosis to reproduction of new cells for growth and to replace damaged or worn-out cells, such as skin cells. Mitosis serves as Mitosis the main asexual reproductive mechanism for a large number of single-celled organisms.

compare and summarize the three stages of cellular respiration
Cellular respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. Glycolysis is an anaerobic process. The other two stages are aerobic processes. The products of cellular respiration are needed for photosynthesis, and vice versa.
The cytoplasmic mechanism known as glycolysis converts glucose into two molecules with a total of three carbons and energy. Two molecules each of ATP, NADH, and pyruvate are generated during glycolysis: As glucose is broken down aerobically through catabolism, ATP, NADH, and pyruvate are produced as energy. Pyruvate then enters the citric acid cycle to create additional energy. Plants manufacture oxygen and sugar-based energy through a process known as photosynthesis, which uses sunlight, water, and carbon dioxide. When sunshine and water are present, plants use a process called photosynthesis to make food. Absorption of light, electron transfer, ATP production, and carbon fixation are the several stages of photosynthesis.

Suppose there were many chloroplasts in the cells of the upper epidermis. How would that change the amount of sunlight reaching the chloroplasts in the palisade layer?
Suppose there were many chloroplasts in the cells of the upper epidermis. The change the amount of sunlight reaching the chloroplasts in the palisade layer is that: The palisade mesophyll chloroplasts would receive less light if the top epidermis contained chloroplasts since they would absorb the majority of the sun's energy.
Do chloroplasts exist in the top epidermis?A single layer of cells, with few or no chloroplasts, makes up this layer. Since the cells are relatively transparent, most of the light that reaches them can reach the cells below. A waxy, waterproof cuticle covers the upper surface of the leaf, preventing water loss from the leaf.
Therefore, Palisade cells are the ones with the most chloroplasts per cell, making them the main location of photosynthesis in the leaves of plants that have them. Photosynthesis is the process by which light energy is transformed into the chemical energy of carbohydrates.

what is the definition of epistasis 1 point
The state known as "epistasis" occurs when the expression of one or more additional genes alters (e.g., masks, inhibits, or suppresses) the expression of a specific gene.
Epistasis refers to the interaction of genes that influences a phenotype. One phenotype with different properties can be determined by a conditional relationship between two genes. Genes can either work together to form a new trait or can hide one another so that only one is identified as "dominant." When it comes to gene pathways, this is typically seen since the presence or absence of one gene product directly impacts the expression of another gene within the pathway. This is also known as allelic complementation or interallelic complementation.

Based on the figure above, which of these experimental treatments would increase the rate of sucrose transport into the cell? 1. decreasing extracellular pH 2. adding an inhibitor that blocks the regeneration of ATP 3. decreasing cytoplasmic pH 4. adding a substance that makes the membrane more permeable to hydrogen ions 5. decreasing extracellular sucrose concentration
Based on the sucrose uptake model, experimental treatments that increase the rate of sucrose transport into cells is decreasing extracellular pH.
Is sucrose used in transportation? Sucrose is synthesized in the cytoplasm, translocated from cell to cell across the plasmodesmata or membranes, and either compartmentalized or transported to the apoplasm for uptake by neighboring cells. Sucrose, a relatively large polar compound, requires proteins to facilitate efficient membrane trafficking.Sucrose reaches the sieve tube via plasmodesmata and allows cell-to-cell diffusion in species such as gourd. It is converted into larger molecules (RFOs) by the sequential addition of galactosyl residues in modified companion cells (CCs) called intermediate cells.In plants, sucrose is the major transport form of photoassimilated carbon, the source of the carbon skeleton, and the energy source for non-photosynthetic plant organs (sink organs). As a molecule to be transported over distance, sucrose must pass through a series of membranes.Can cells take up sucrose?Dietary carbohydrates of particular importance include starches and disaccharides such as lactose and sucrose. None of these molecules can be absorbed simply because, unlike monosaccharides, they have no transporters to transport them, and they cannot cross cell membranes, unlike monosaccharides.
