Explanation:
Which substance is an inorganic molecule made during photosynthesis?
O
A. C6H1206
B. 02 A
OC. NADPH
OD. CO₂
Answer:
it is carbon from carbon dioxide
Explanation:
it can be incorporated into organic molecule
Utilizing light, plants use photosynthesis to convert the inorganic chemicals carbon dioxide and water into glucose, hence option D is correct.
How, an inorganic molecule made during photosynthesis?Energy is needed to power the chemical reaction in photosynthesis. A reaction that is endothermic is photosynthesis. This indicates that without energy, it cannot happen (from the Sun).
Photosynthesis is a process used by all green plants and a few other autotrophic organisms to create nutrition from carbon dioxide, water, and sunlight. Oxygen is a byproduct of the photosynthesis process.
Plants and other creatures employ a process called photosynthesis to transfer light energy, typically from the Sun, into chemical energy that can then be released to power the organism's activities (energy transformation).
Therefore, option D is correct.

The metabolic machinery of the cell, highly organized structures that carry out specific functions for the cell are __________.
The highly organized structures that carry out specific functions for the cell are called organelles.
What are organelles?Inside cells, organelles are specialized structures that carry out a variety of tasks. Literally, the phrase refers to "tiny organs." Organelles provide specialized duties to keep a cell alive, just like organs like the heart, liver, stomach, and kidneys serve specific roles to keep an individual alive.
Prokaryotic cells and eukaryotic cells, which are divided into two distinct groups based mostly on the existence of one organelle, the nucleus, are types of cells. Eukaryotic cells have nuclei, but prokaryotic cells do not. The nucleus is a sizable organelle that houses DNA and acts as the brain of the cell. Prokaryotic cells often make up single-cell creatures, whereas eukaryotic cells typically make up multicellular species.
Therefore, organelles are the structures of the cell that carry out its specific functions.

Hypoblast is the second layer of the embryonic disc that creates the yolk sac, Epiblast is one of the two layers that creates the three basic germ layers (ectoderm, definitive endoderm, and mesoderm), amnionic ectoderm, and extraembryonic mesoderm.
The embryonic disc is made up of two parts: epiblast and hypoblast.
The epiblast and hypoblast are formed by layering the core cell mass. As a result, the inner cell mass gives rise to the epiblast and hypoblast.
Additionally, epiblast cells are topped by hypoblast cells.

WRITE ABOUT A THEME: ORGANIZATION Cells are the basic units of structure and function in all organisms. A key feature in the life cycle of plants is the alternation of multicellular haploid and diploid generations. Imagine a lineage of flowering plants in which mitotic cell division did not occur between the events of meiosis and fertilization (see Figure 30.12). In a short essay (100-150 words), describe how this change in the timing of cell division would affect the structure and life cycle of plants in this lineage.
The alternation of generations is a phenomenon present in the life cycle of all plants and also in some algae and fungi. This alternation means that during the life of the plant it will go through a haploid phase, called the gametophyte, which will alternate with the diploid generation, known as the sporophyte. The change in cell division time would affect the structure and life cycle of plants in this lineage because the haploid time, where the plant does not reproduce, will increase, making the plant inferred and not producing offspring for a longer time.
What happens during cell division?Before any cell division, DNA duplication occurs during interphase. The G2 phase corresponds to the interval between DNA synthesis and mitosis. The cell continues to grow and produce proteins.
With this information, we can conclude that The classification of cells in diploid and haploid refers to the chromosome set of each one.

Acidosis is the inability of the kidneys not being able to regulate or remove acids in the blood. When the lungs are not able to function at their normal speed, respiratory acidosis can occur.
Acidosis is caused by an overproduction of acid that builds up in the blood or an excessive loss of bicarbonate from the blood (metabolic acidosis) or a buildup of carbon dioxide in the blood that results from poor lung function or depressed breathing (respiratory acidosis).
Acidity and alkalinity are expressed on the pH scale, which ranges from 0 (strongly acidic) to 14 (strongly basic or alkaline). A pH of 7.0, in the middle of this scale, is neutral. Blood acidity increases when people ingest substances that contain or produce acid or when the lungs do not expel enough carbon dioxide.

explain one way in which facilitated diffusion is the same as simple diffusion and one way in which it is different from simple diffusion. quizlet
Facilitated diffusion is similar to simple diffusion in that it consumes no energy and diffuses material along a gradient. Facilitated diffusion differs from simple diffusion in that it necessitates the presence of carrier proteins.
Simple diffusion and assisted diffusion are two forms of passive transport techniques in which molecules are transported across the cell membrane. It leverages natural entropy to shift molecules from higher to lower concentrations until the concentrations are equalized. As a result, no ATP energy is required for molecular movement. Passive transport is classified into four types: osmosis, simple diffusion, assisted diffusion, and filtration. The primary distinction between simple diffusion and facilitated diffusion is that simple diffusion is an unassisted type of diffusion in which a particle moves from a higher concentration to a lower concentration across a membrane, whereas facilitated diffusion is the transport of substances across a biological membrane through a concentration gradient via a carrier molecule.
