in which two ways do plant cells use the sugar made in photosynthesis?
A. to store inorganic matter
B. to produce phosphate group
C. to supply the plant with energy for life
D. to make other types of organic molecules
Answer:
C, and D
Explanation:
Hope it helps!
The two ways in which plant cells use the sugar made in photosynthesis are C. to supply the plant with energy for life and D. to make other types of organic molecules.
C. to supply the plant with energy for life: The sugar produced during photosynthesis, typically in the form of glucose, serves as a primary source of energy for plant cells. Through cellular respiration, the sugar is broken down in the mitochondria, releasing energy in the form of ATP (adenosine triphosphate). ATP is the energy currency of cells and is used for various metabolic processes necessary for plant life, such as growth, reproduction, transport of molecules, and maintaining cellular functions.
D. to make other types of organic molecules: Plant cells utilize the sugar produced in photosynthesis as a building block for the synthesis of other organic molecules. Glucose serves as a precursor for the biosynthesis of complex carbohydrates, such as starch and cellulose, which are important for energy storage and structural support in plants. Additionally, the sugar is used to synthesize lipids, proteins, nucleic acids, and other biomolecules that are essential for various cellular processes, including growth, development, signaling, and defense mechanisms.
By using the sugar produced in photosynthesis to supply energy and as a source of carbon and energy for synthesizing other organic molecules, plant cells ensure their own survival, growth, and overall metabolic functions. This efficient utilization of sugars allows plants to carry out necessary processes and adapt to changing environmental conditions.

Describe and compare the sources of Earth's External Energy. (earth and space science)
The sun is Earth's primary source of external energy. It perfectly heats our planet to the point where life can flourish.
Sunlight is a clean, renewable source of energy. It is a sustainable resource, meaning it doesn't run out, and can be maintained because the sun shines almost every day.
In one second the sun converts 4 million tons of mass into energy in the form of heat and electromagnetic radiation.
The solar constant is how much sunlight power reaches the earth. On average, this value is roughly 1400 watts-per-square-meter. In terms of energy, this equates to about 1.8 × 10¹⁷ joules/second.
Out of the average, total amout of mass the sun converts to energy, the earth captures only 6.25 × 10-⁸%. This is an extremely small percentage , but if it all could be harnessed to use for our electricity needs, we would have more than enough.
Solar energy is perennial and non-polluting.

Mutations are alterations to a dna sequence. they can cause diseases and conditions, but they are also tools in evolution because they provide new variations in the genetic pool. list and briefly describe the two processes that lead to variation in offspring with the same parents that are not a result of mistakes in the dna.
The two processes that lead to variation in offspring with the same parents that are not a result of mistakes in the dna are:
i) crossing over ii) random fertilization
The exchange of genetic material between non-sister chromatids of homologous chromosomes, or crossing-over, takes place during prophase I. Remember that homologous chromosomes align in pairs, gene for gene down their whole length, generating a configuration with four chromatids known as a tetrad during prophase I. The chromatids are now very close to one another, and some material from two chromatids switches chromosomes, or breaks off and reattaches to the homologous chromosome at the same location. Within the same pair of homologous chromosomes, this genetic material exchange can take place numerous times, resulting in different gene combinations. The term "recombination" also applies to this procedure.
Genetic diversity is endlessly possible as a result of sexual reproduction. In other words, sexual reproduction produces genetically distinct offspring. Two gametes combine during sexual reproduction to create an offspring. But out of the millions of potential gametes, which two will it be? This is probably just a matter of luck. It is without a doubt another source of genetic diversity in progeny. This practice is called random fertilization. produces genetic variation with endless potential. In other words, sexual reproduction produces genetically distinct offspring. They are different from one another as well as from their parents. There are several reasons why this happens.

when na⁺ diffuses into the cell, the cell becomes more depolarized. na diffusing into the cell causes more na gates to open, which is a positive feedback loop.
The cell becomes more depolarized when Na+ diffuses into the cell, this a positive feedback loop.
The membrane potential depolarizes when it gets less negative (more positive). Depolarization may result from the opening of channels that allow positive ions to enter the cell. An illustration would be the opening of Na+ entry channels in cells. Potential for action A sufficiently substantial depolarization event, possibly brought on by several concurrent depolarizing inputs, can result in the generation of an action potential. In contrast to a graded potential, an action potential is an all-or-nothing event: whether it happens or not, it will always be the same magnitude. When a depolarization causes the membrane voltage to rise beyond a threshold level, an action potential is initiated. The voltage-gated Na+ channels in the membrane open at this threshold, allowing a flood of sodium ions to enter the cell. The quick increase in membrane potential caused by the influx of sodium ions triggers a positive feedback cycle that is powered by the voltage-dependent activation of the Na+ conductance.
