In 4 sentences or less describe what happens during photosynthesis.
Answer:
Photosynthesis is the process in which plants make their own food using carbon dioxide, water and sunlight. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Plant and animal cells get energy from sugar. This process is called cellular respiration. Which of the following suggests this process obeys the law of conservation of mass?
a.The mass of the reactants is less than the mass of the products.
b.The mass of the reactants is greater than the mass of the products.
c.If the mass of the reactants increases, then the mass of the products increases an equal amount.
d.If the mass of the reactants increases, then the mass of the products decreases an equal amount.
Answer:
A process that obeys the law of conservation of the mass suggests that if the mass of the reactants increases, then the mass of the products increases an equal amount (option c).
Explanation:
The law of conservation of mass or matter was proposed by Mikhail Lomonosov in 1748 and ratified by Antoine Lavoisier in 1785, being a universally accepted law.
According to the law of conservation of mass, in isolated systems the amount of reagents must be equal to the amount of products derived from a reaction. For this reason, if in a reaction the amount of reactants is increased, the amount of products increases proportionally.
The other options (a, b and d) are not correct because they do not obey the law of mass conservation.The basis for the energy in an ecosystem is provided by?

where does respiration take place in a cell? (I need the middle school level answer)
Answer:
mitochondrion
Explanation:
The nzymatic reactions of cellular respiration begin in the cytoplasm, but most of the reactions occur in the mitochondria. Cellular respiration occurs in the double-membrane organelle called the mitochondrion. The folds in the inner membrane are called cristae.
How does photosynthesis and cellular respiration move carbon, nitrogen, and water through the different Earth systems (biosphere, atmosphere, hydrosphere, and geosphere)?
Answer:
well the plants live and die from life to death they get there nutrients from water from rain. and oxygen from the air and nitrogen from the ground. the plant grows and dies. when it dies it decompose and puts nitrogen back into the soil along with the seeds that where produced in it's life time.
Photosynthesis and cellular respiration move carbon, nitrogen and water through the different Earth systems by exchanging these elements between the biosphere, atmosphere, hydrosphere and geosphere through the processes of absorbing, converting, releasing and exchanging them.
What is photosynthesis and cellular respiration?Both photosynthesis and cellular respiration also involve the movement of nitrogen and water through the different Earth systems. Nitrogen is a critical element for the growth of plants and is taken up by plants through the roots, it is a key component of proteins and nucleic acids, and also plays a role in the formation of chlorophyll, which is essential for photosynthesis. Water is also essential for photosynthesis, as it is needed to convert light energy into chemical energy.
In summary, photosynthesis and cellular respiration are closely linked processes that move carbon, nitrogen, and water through the different Earth systems by taking in and releasing these elements in the atmosphere, hydrosphere, and geosphere, and providing energy for the biosphere.

How is energy stored and released by ATP?
Answer:
Energy is stored as stored chemical energy in the bonds between phosphate groups in the ATP molecules. When ATP is hydrolyed and the bonds between phosphates are broken, the energy is released.
What is base pairing? (and Chargaff's rule)?
Answer:
A base pair (bp) is a fundamental unit of double-stranded nucleic acids consisting of two nucleobases bound to each other by hydrogen bonds. They form the building blocks of the DNA double helix and contribute to the folded structure of both DNA and RNA. The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G).
Explanation:
Chargaff's rules state that DNA from any species of any organism should have a 1:1 stoichiometric ratio of pyrimidine and purine bases and, more specifically, that the amount of guanine should be equal to cytosine and the amount of adenine should be equal to thymine. This pattern is found in both strands of the DNA.

Gas Giants - Jupiter, Saturn, Uranus, and Neptune
Ice Giants - Uranus and Neptune
Explanation:
Gas plants are the planets that are composed mostly of the gases in them such as helium and hydrogen found in Saturn and Jupiter planets there are four planets known as the gas giants that are Jupiter, Saturn, Uranus, and Neptune. However, Uranus and Neptune planets are known as ice giants as these two planets are cold and remote and made up of completely different gases from the other two gas giants.
Terrestrial planets are the planets that are more rocky and compact in terms of their surface and these planets are inner planets of our solar system that are Mercury, Venus, Earth, and Mars.
Answer:
Terrestrial planets- Venus mercury Mars and Earth.
Gas giants - Jupiter and Saturn.

Which statement best describes how the environment influences the traits of an individual?
The environment influences the gene expression which can change the genotype.
The environment influences the gene expression which can change the phenotype.
The environment influences only external factors.
The environment influences only internal factors.
Answer: The environment influences the gene expression which can change the phenotype.
Explanation: TRUST
The environment influences the gene expression which can change the genotype. The correct option is A.
What is gene expression?The methodology by which a gene in a cell is activated to produce RNA and proteins.
Gene expression can be assessed by examining the RNA, the protein produced from the RNA, or whatever the protein does in the cell.
The environment can impact gene expression in a life form, along with the outer environment in which the species is positioned or evolves, as well as the organism's internal world, which encompasses factors such as hormones and metabolism.
Several factors influence gene expression, which would include molecules within the cell, mutations that cause dominant damaging consequences and haploinsufficiency, signaling molecules from neighboring cells and the environment, and epistasis.
The environment influences an individual's genotype but not his or her phenotype.
Thus, the correct option is A.
