Answer: Glucose (and also oxygen)
Explanation: Photosynthesis is the process of turning CO2 and H2O in Glucose and oxygen where the chloroplasts use the energy from the sun to rip apart the molecules and rearrange them into glucose, a useable form of energy, and oxygen, a bi product that gets released into the atmosphere.
How do muscle cells access what they need to keep producing energy
Muscle cells access what they need to continue producing energy through chemical energy from ATP to transform it into mechanical energy.
Muscle cells are elongated cells whose length can reach several centimeters.
The muscle uses ATP (energy) to carry out conformational changes in its molecular structure => variation in the length of the sarcomere.
Adenosine triphosphate (ATP) is the basic source of energy for muscle contraction.
Each link stores 7300 calories of energy per mole of ATP under normal conditions and when a phosphate radical is separated from the molecule, these calories are available providing the energy necessary for muscle contraction.
The muscle cell has three mechanisms to resynthesize ATP:
ATP synthesis through phosphocreatine.
Anaerobic glycolysis process with the transformation of muscle glycogen into lactate.
From oxidative phosphorylation.
ATP synthesis through phosphocreatine consists of the transfer of energy from phosphocreatine to ADP so that it can reincorporate a phosphate group to its molecule and transform it into ATP.
So the energy that has been released in the hydrolysis of PCr is directly used to resynthesize ATP from ADP.
Therefore, we can conclude that muscle cells access what they need to continue producing energy through the chemical energy of ATP to transform it into mechanical energy.

what can we infer if we see a large number of mitochondria in a cell?
Answer: It means the cell has a high metabolic demand.
Explanation:
A high metabolic demand means that the cell requires a large amount of energy released in the process called cellular respiration. The mitochondria are where most of the energy of the cell is made.

what organelle is critical for endocytosis and exocytosis to occur
Answer:
Endoplasmic Reticulum
Explanation:
The cell membrane, also known as the plasma membrane, is an organelle that is essential for both endocytosis and exocytosis to take place.
Thus, The cell membrane, which encloses the cell and separates its internal contents from the outside environment, is a barrier that is selectively permeable.
The process by which cells absorb materials from their surroundings is known as endocytosis. The cell membrane invaginates and creates a vesicle that encloses the substance being transported into the cell during endocytosis.
The vesicle is subsequently taken inside and moved into the cytoplasm of the cell. In this process, the cell membrane is essential because it helps the endocytic vesicle develop.
Thus, The cell membrane, also known as the plasma membrane, is an organelle that is essential for both endocytosis and exocytosis to take place.

Why does neurones contain many mitochondria and many ribosomes?
Answer:
Neurons depend on mitochondria. ATP generation by mitochondrial respiration in the brain consumes 20% of the body's oxygen although the brain is only 2% of the mass of the body (Attwell and Laughlin, 2001). ... Every part of the neuron requires ATP and therefore requires mitochondria to be present.The dendritic processes and spines of neurons are essentially expansions of cytoplasm containing most of the organelles found in the cell body. ... Rough endoplasmic reticulum and ribosomes are present in large but not small dendrites.

4. Explain or give the importance of the sun in relation with the weather of any place on planet earth?
Answer:
1. Wind is an important element when it comes to current weather and predicting future forecasts. Wind transports moisture and temperature from one area to another, therefore weather conditions change with the shift of wind direction.
2.All plants and animals, including humans, are exposed to the dangers of solar UV radiation; it can cause significant damage to plants, as seen in crop yield reduction and leaf burn, and can damage animal skin health.
3.sun-light is a key energy source for all plants. Through a process called photosynthesis, plants absorb energy from the sun, which fuels the processes necessary for survival.
4.The Sun warms our planet, heating the surface, the oceans and the atmosphere. This energy to the atmosphere is one of the primary drivers our weather. Our climate is also strongly affected by the amount of solar radiation received at Earth.

1. describe the stages of the cell cycle
2. use a model to illustrate the role of cellular division in the formation of new cells
3. describe the structure of a chromosome
4. follow chromosomes through the processes of mitosis and cytokinesis
Answer:
1.The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells.
2. In the Picture Linked.
3. Chromosome help ensure that DNA is replicated and distributed appropriately during cell division. Each chromosome has a centromere, which divides the chromosome into two sections – the p (short) arm and the q (long) arm.
4. Mitosis occurs at the sites of growth and development of new tissues. Here are the stage of mitosis Below:
Prophase
This is the initial phase. The chromosomes in the nucleus become visible as thin coiled threads. In animals, the centrosome found in the cytoplasm divides to form two centrioles. The chromosomes become tightly coiled and shorter. From each centriole, fine fibers develop and elongate to form spindle apparatus. The nucleolus becomes dispersed in the nucleus and disappears. The nuclear membrane also break and disappears.
Metaphase
The pairs of chromatids align along the equator of the spindle apparatus and are attached to it at their centromeres.
Anaphase
The centromere of each chromosome splits and the chromatids separate. Each chromatid moves to the opposite poles of the cell. The chromatids appear as V--shaped.
Telophase
The spindle fibers disintegrate and disappear. New nuclear membrane forma around each set of chromatids. A nucleolus develops in the nucleus of each daughter cell. The cytoplasm now divides in a process called cytokinesis. In animals, an invagination develops at the plasmalemma near the equator of the cell.
Relationship between mitosis and cytokinesis:
Mitosis is the division of a nucleus. Cytokinesis is the division of the cytoplasm. If mitosis occurred without cytokinesis, the cell would contain two nuclei and twice the DNA. If cytokinesis occurred without mitosis , one of the new cells would lack DNA and a nucleus altogether.

which structures are found in palisade cells and liver cells
Answer:
All cells contain a nucleus and a nuclear envelope and the liver cell is no exception. It has exactly the same control over the cell as the palisade nucleus does. To keep it all together, it is surrounded by a cell membrane.
Explanation:
Since a liver cell is an animal cell, it lacks chloroplast. Below the epidermis of the leaves is a palisade cell. It participates actively in photosynthesis, chloroplasts are present.
What structures are found in liver cells?Liver cells lack a cell wall but do have a nucleus and a cell membrane. It receives blood from two main sources: The Hepatic Portal Vein, which delivers blood from the digestive tract that is nutrient-rich.
The nucleus and nuclear envelope are components of every cell, including liver cells. The cell is under the exact same management that the palisade nucleus is. It is encased in a cell membrane, which serves to keep everything together.
Therefore, as an animal cell, the liver lacks the cell wall, chloroplast, and big vacuole that are often seen in plant cells.
