How does the carbon dioxide necessary for photosynthesis enter plants? a. through their roots b. through openings in the leaves called stomata c. the plants produce their own complete supply d. none of the above please select the best answer from the choices provided a b c d
The process by which plants make their own food is called photosynthesis. The raw materials of it are carbon dioxide coming from stomata, water and sunlight.
What is stomata?Stomata is the opening for gaseous exchange and transpiration, present in epidermis of leaf.
Stomata are provided by two guard cells, which shrink and swell in order to open or close the stomatal pore respectively.
The carbon dioxide necessary for photosynthesis enter plants through these openings called stomata.
Thus, option b is correct.

Which statement BEST describes what happens during the S-phase of the cell cycle?
A.Protein synthesis needed for spindle formation and mitosis.
B.DNA replication where the amount of genetic material is doubled.
C.The cell partitions the two copies of genetic material into the two daughter cells.
D.Cell division occurs and two cells are left; thus the cell cycle begins again.
Answer:
B
Explanation:
The S phase of a cell cycle occurs during interphase, before mitosis or meiosis, and is responsible for the synthesis or replication of DNA. In this way, the genetic material of a cell is doubled before it enters mitosis or meiosis, allowing there to be enough DNA to be split into daughter cells.

Additional vascular tissue produced as secondary growth in a root originates from which cells?.
Answer:
The vascular cambium produces new vascular tissue and is responsible for most of the radial expansion of stems and roots.
Explanation:
Does this answer your question???
Additional vascular tissue produced as secondary growth in a root originates from Vascular cambium cells.
What is secondary growth?
Secondary growth happens in the vascular cambium of those plants, that is a skinny layer of tissue containing actively dividing cells. The vascular cambium is a meristematic tissue that develops among the stem's number one xylem and number one phloem.
The Vascular Cambium and Secondary Growth. The vascular cambium and cork cambium are secondary meristems which can be fashioned in stems and roots after the tissues of the number one plant frame have differentiated. The vascular cambium is accountable for growing the diameter of stems and roots and for forming woody tissue.

How many oxygen molecules can one hemoglobin carry.
Answer:
The hemoglobin molecule has four binding sites for oxygen molecules: the iron atoms in the four heme groups. Thus, each Hb tetramer can bind four oxygen molecules.
Answer:
Oxygen binds reversibly to harem, so each hemoglobin molecule can carry up to four oxygen molecules. Hemoglobin is an allosteric protein; the binding of oxygen to one harem group increases the oxygen affinity within the remaining harem groups.

In a multicellular organism, it is cell-to-cell communication that allows the trillions of cells to coordinate activities, including during development and regeneration. The three stages of cellular communication include: reception, transduction, and response. This study determined the key steps of a cell communication pathway involved in salamander limb regeneration. After amputation of a front salamander limb, the severed axons retract within the stump and grow back along the nerve sheath. To elucidate the molecular mechanisms, the researchers set up a series of controlled experiments to determine the events in salamander limb regeneration. Drag the general cell communication steps of the regeneration experiment into the correct order.
The process of amputation will interfere with the ability of cells to communicate with each other.
What is cell to cell communication?The body of whole multicellular organisms have a lot of cells which are differentiated hence they perform diverse functions. The essence of cell differentiation is to allow different cells to perform different functions.
The question is incomplete hence we can not give here the process of cell regeneration. However, we know that the process of amputation will interfere with the ability of cells to communicate with each other.

D) According to the graph, obesity and diabetes are intertwined, which could be why obesity and diabetes are linked.
E) Diabetes had the greatest rise in prevalence in 1997 until 2000, with prevalence percentages between about 76% to 78%.
Explanation: Explanation for these answers are below:
D) Looking at the graph, obesity and diabetes had similar prevalences in 1997 and 1998, and started to part ways a little in 1999. In fact, even without the graph, scientists have known for a long time that people who have obesity also have diabetes. This graph supports that claim because of how closely linked diabetes and obesity are and how similar the prevalence percentages are.
E) Diabetes had the greatest rise in 1997 to 2000, which had a 78% prevalence by 2000. Obesity had very similar prevalence percentages from 75.5% to 77% in 1997 to 2000.

Proteins that use energy from ATP hydrolysis to change the locations and compositions of nucleosomes are called ATP-dependent___complexes.
Answer:
Chromatin-remodeling
Explanation:
In eukaryotes, DNA is tightly wound into a complex called chromatin. Thanks to the process of chromatin remodeling.
Chromatin-remodeling complexes use energy from ATP hydrolysis to alter the arrangement of nucleosomes, making the DNA more accessible to other proteins.
Why can we not see the South Pole-Aitken basin from Earth? The crater is too small to see from Earth. The moon rotates too fast to see any surface features. The crater is on the far side of the moon, which we cannot see. The sun never shines on that side of the moon, so the crater is always in shadow.
