6 How can you determine the origin of the oxygen released by photosynthesis?
Answers
Answer:
because all green plants release oxygen and non- green plants do not release oxygen.
Explanation: One of the first uses of an isotopic tracer in biology was in the determination of the source of the oxygen produced by photosynthesis. Using a heavy isotope of oxygen, 18O, to label one of the two reactants in the photosynthetic process, Samuel Ruben and collegues at UC Berkeley were able to determine that the oxygen gas came not from carbon dioxide, but water.

Explanation:
Scientists believe that in order for humans to see things, the brain has to make certain assumptions which are done based on previous scenes that it has interpreted before because the eyes do not provide it with complete data. .
One of those assumptions is that light comes from above which is why the shape of a picture can change depending on the lighting in it.
Zeke is trying to plant a garden but he does not have much space. Zeke decides to trim the ends of the roots of the plants he is putting in his garden. After a week, Zeke notices that his plants did not grow at all. Explain why this happened.
Answers
Answer:
Zeke has cut the meristematic cells at the root tip, hence, the root will not elongate to get nutrients and water needed for plant growth.
Please find more explanation below
Explanation:
The root tips of a plant contain cells that actively divide, hence, causing growth or elongation of the roots. This allows the root to grow or penetrate into the soil in search of nutrients and water needed for the plants growth.
According to this question, Zeke decided to trim the ends of the roots of certain plants he is putting in his garden due to lack of space. However, he later discovered that these plants did not grow at all. This is because Zeek has cut off the root tip that contains the MERISTEMATIC CELLS responsible for the elongation of the roots into the soil. Hence, the roots are unable to absorb water and nutrients for the plant, preventing the overall growth of the plant.
As the zygote goes through mitosis and creates more cells. Each cell is called a stem cell. In order to become a certain type of cell, these cells will become Or This means they will turn Genes for the type of cell they are becoming, and turn Genes for the type of cell they won't be.
Answers
Answer:
differentiated; on; off
Explanation:
As the zygote goes through mitosis and creates more cells. Each cell is called a stem cell. In order to become a certain type of cell, these cells will become differentiated Or This means they will turn Genes on for the type of cell they are becoming, and turn Genes off for the type of cell they won't be.
Stem cells become specialized cells through the process of differentiation. The stem cells all have identical DNA in them. They become specialized for a particular function (s) through the process of differentiation. During this process, some specific genes are either turned on or off. Cells in which the same genes are expressed become specialized for similar functions and can then come together to form a tissue.

what is photosynthesis
Answers
Photosynthesis is the process used by plants, algae and certain bacteria to harness energy from sunlight and turn it into chemical energy. Here, we describe the general principles of photosynthesis and highlight how scientists are studying this natural process to help develop clean fuels and sources of renewable energy.
Types of photosynthesis:There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis. The general principles of anoxygenic and oxygenic photosynthesis are very similar, but oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria.
During oxygenic photosynthesis, light energy transfers electrons from water (H2O) to carbon dioxide (CO2), to produce carbohydrates. In this transfer, the CO2 is "reduced," or receives electrons, and the water becomes "oxidized," or loses electrons. Ultimately, oxygen is produced along with carbohydrates.
Explanation:
photosynthesis the process by which green plants and some other organisms use sunlight to synthesize nutrients from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a by-product.

Some genes are important enough to be called "molecular switch" or "master" genes. What is the purpose of these genes?
A. They control when other genes are expressed
B. They determine the organization of the genome
C. They regulate cell metabolism
D. They modulate the rate of translation
Answers
Answer:
Genes called "molecular switch" or master genes have the purpose of control when other genes are expressed (option A).
Explanation:
Master gene is so named because it has the function of controlling the behavior of other genes, organizing their functions and regulating when they can be expressed.
The name of molecular switch is synonymous with the master gene, since its activation determines the genetic regulation necessary to establish cell differentiation and even the determination of the sex of some species.
The other options are not correct because:
B. Master genes do not determine the organization of the genome .
C. Regulation of cell metabolism depends of substances as hormones and enzymes.
D. The rate of translation does not depend on the activity of master genes.

How does genetic variation allow humans to survive long-term?
Which type of reproduction is responsible for genetic variation?
Answers
Answer:
Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation. Some new alleles increase an organism's ability to survive and reproduce, which then ensures the survival of the allele in the population. Sexual reproduction promotes genetic variation by producing different gene combinations. Meiosis is the process by which sex cells or gametes are created. Genetic variation occurs as alleles in gametes are separated and randomly united upon fertilization.
