02.07 photosynthesis
Answer:
Photosynthesis 02.07RITA RIFFI
sunlight is made in to a chemical energy using chlorophyll. Then uses energy to convert co2 and water in to glucose.
Photosynthesis is the process by which plants, algae, and some bacteria convert sunlight, carbon dioxide, and water into glucose (a type of sugar) and oxygen. This process occurs in the chloroplasts of plant cells.
Here is a step-by-step explanation of the process of photosynthesis:
1. Light Absorption: Chlorophyll, a pigment found in chloroplasts, absorbs sunlight. This light energy is essential for photosynthesis to occur.
2. Conversion of Light Energy: The absorbed light energy is used to power a series of chemical reactions that convert carbon dioxide and water into glucose. This process is called the light-dependent reaction.
3. Production of ATP and NADPH: During the light-dependent reaction, energy is stored in the form of ATP (adenosine triphosphate) and NADPH (nicotinamide adenine dinucleotide phosphate). These molecules act as energy carriers in the next step of photosynthesis.
4. Carbon Fixation: The ATP and NADPH produced in the light-dependent reaction are used in the Calvin cycle, also known as the light-independent reaction or the dark reaction. In this step, carbon dioxide is converted into glucose using the energy stored in ATP and NADPH.
5. Release of Oxygen: As a byproduct of photosynthesis, oxygen gas is released into the atmosphere. This oxygen is essential for the survival of many organisms, including humans.
Overall, photosynthesis plays a crucial role in the Earth's ecosystem by providing oxygen and producing food for organisms. It is an essential process that sustains life on our planet.

what ions are more concentrated inside the cell than the outside?
Answer:
ions concentrate inside than the cell outside
Explanation:
When the membrane is at rest, are the sodium ions more concentrated inside the cell or outside? Where are the potassium ions more concentrated?
Sodium ions are more concentrated outside the cell, and potassium is more concentrated inside.
Sodium ions are more concentrated outside the cell, and potassium is more concentrated inside.
What are the functions of sodium ions?The Importance of Sodium in Biology Sodium ions are found primarily inside human cells, such as Nerve Cells. They are responsible for regulating the flow of water across the membrane. They are required for the transport of sugars and amino acids into the cells of an organism.
Sodium ions are required for the absorption of glucose and amino acids in the small intestine. These molecules are absorbed into the intestinal cells via co-transport channels that are driven by sodium ions.
When the cell membrane is depolarized by a few millivolts, sodium channels activate and inactivate within milliseconds. Influx of sodium ions through the integral membrane proteins comprising the channel depolarizes the membrane.

Which would be the best evidence that a cell is using active transport to move a substance across its cell membrane?
Α.
Substances are moving rapidly across the cell membrane.
B. ATP is being rapidly consumed near the cellular membrane,
C. Substances are moving from high to low concentrations.
D. Substances are moving through channels in the cell membrane
Answer:D. Substances are moving through channels in the cell membrane
Explanation:
In case of active transport, ATP is being rapidly consumed near the cellular membrane. Thus, the correct option is B.
What is Active transport?Active transport is the movement of molecules or ions across a cellular membrane from a region of its lower concentration to a region of its higher concentration against the concentration gradient of the molecules or ions. Active transport requires cellular energy to achieve this movement of molecules or ions. The cellular energy is supplied in the form of ATP (Adenosine triphosphate) molecules.
The transport of molecules occurs through transport proteins such as carrier proteins and channel proteins against the concentration gradient.
Therefore, the correct option is B.

What is meiosis ?
Meiosis is the process where a single cell divides twice to produce four four haploid daughter cells which are otherwise called as gametes; It can occur in two substages such as meiosis I and meiosis II.
Meiosis I consist of substages like Prophase I where nuclear envelope disintegrates, Chromosomes begin to condense, Spindle fibers appear.
Secondly Prometaphase I where Spindle fibers attach to the centromere followed by Metaphase I.
The homologous chromosomes align at the equatorial plate, Anaphase I where he homologous chromosomes move towards the opposite poles.
Telophase I where Spindle fibers disappear, Cytokinesis I where the cytoplasm and the cell division result in 2 non-identical haploid daughter cells. same events are occurred in meiosis II.

What type of symbiosis occurs when one organism benefits and the other is harmed?
Answer:
Parasitism
Explanation:
In this a parasite takes its food or other needs from the host but later harms the host too.Some examples like leeches who takes blood from our body but harms us tooParasitism is an ecological relationship between two organisms in which one organism benefits while the other organism suffers. It may also be a type of symbiosis.
The majority of microorganisms investigated in medical microbiology are parasitic and prey on human tissue. Parasitic microbes, for instanse, cause cholera, leishmaniasis, and giardia. Any relationship between two or more biological species is referred to as symbiosis. Such relationships are typically long-term and have a significant impact on one or both organisms' fitness. Benefits and physical characteristics distinguish symbiotic relationships. Mutualism, defined as a relationship in which both species benefit, is very common in nature. There are numerous examples of mutualistic bacteria in the abdomen that aid digestion in both humans and animals in microbiology. A commensal relationship is one in which one species benefits while the other is unaffected. Humans have a variety of commensal bacteria in their bodies that do not harm them but are necessary for survival, like when dead skin is consumed by bacteria.
