B.Interphase is made up of the G1, S, and G2 phase and is the portion of the cell cycle where cellular contents are duplicated.
C.Interphase is made up of the G1, S, G2, M, and C phase and is the portion of the cell cycle where two new daughter cells are formed.
D.Interphase is made up of the C, G1, S, and G2 phase and is the portion of the cell cycle where the genetic information is exchanged between chromosomes during cell division.
Answer:
The correct answer is - option B. Interphase is made up of the G1, S, and G2 phase and is the portion of the cell cycle where cellular contents are duplicated.
Explanation:
Interphase is the phase in the cell cycle in which the cell prepares to go under cell division by growing in size, replicating, or duplicate the cellular contents like DNA or genetic material and prepare for mitosis. Interphase includes the substages G1, S, and G2 phases.
It is known as the longest stage of the cell cycle as it includes four substages that takes time due to growing the cell, double the content and make the cell ready to go under division.

The pyruvate dehydrogenase complex is subject to allosteric control, especially inhibition by reaction products. The main regulatory process controlling pyruvate dehydrogenase's activity in eukaryotes is
Answer:
phosphorylation by ATP and dephosphorylation, which turn off/on the complex
Explanation:
The pyruvate dehydrogenase complex consists of three different enzymes capable of converting pyruvate into acetyl-CoA. The enzymes that form the pyruvate dehydrogenase complex are pyruvate dehydrogenase (E1), dihydrolipoyl transacetylase (E2) and dihydrolipoyl dehydrogenase (E3). In eukaryotic organisms, the pyruvate dehydrogenase complex is controlled by pyruvate dehydrogenase kinase and pyruvate dehydrogenase phosphatase, which turn off and turn on the complex, respectively. In this mechanism, pyruvate dehydrogenase kinase phosphorylates (using ATP) to target serine residues in E1 subunit, while pyruvate dehydrogenase phosphatase dephosphorylates this subunit, thereby deactivating and activating the complex, respectively.

Describe the 4 Phases of Mitosis, the purpose of it and the end products.
Answer:
Mitosis consists of four basic phases: prophase, metaphase, anaphase, and telophase. Some textbooks list five, breaking prophase into an early phase (called prophase) and a late phase (called prometaphase). Cytokinesis typically overlaps with anaphase and/or telophase. ...
Explanation:
Could i have branliest, heart with 5 stars!
Thanks.
Answer:
The four stages of mitosis are known as prophase, metaphase, anaphase, telophase.
Prophase is the starting stage of cell division in eukaryotes. Prophase, in both mitosis and meiosis, is recognized by the condensing of chromosomes and separation of the centrioles in the centrosome.
Metaphase is a stage in eukaryotic cell division in which the chromosomes align on the metaphase plate in the middle of the cell.
Anaphase is a stage during eukaryotic cell division in which the chromosomes are segregated to opposite poles of the cell.
Telophase is the final stage in cell division. During telophase, the nuclear envelopes reform around the new nuclei in each half of the dividing cell.

In recent years, scientists have collected data on populations of Adelie and Gentoo penguins. Adelie penguins are ice dependent. They rely on sea ice as a foraging platform for feeding on prey such a krill and fish, while Gentoo penguins are considered ice-intolerant. How does the data in the graph support or refute the theory of global climate change?
a. The graph refutes this theory, as it shows increases in Adelie and Gentoo penguins.
b. The graph supports this theory, as it shows that penguin populations are fluctuating in number.
c. The graph supports this theory, as it shows a gradual decline in populations of Adelie penguins.
d. The graph refutes this theory, because it does not provide any information on global temperatures.
Answer:
C. The graph supports this theory, as it shows a gradual decline in populations of Adelie penguins.
Explanation:
Since Adelie penguins depend on ice to survive, a decline of ice would spell chaos for their survival. And coupled with the fact global warming means a bigger fluctuation of temperatures and a faster melting of ice on Earth, that would line up with the data of the decreasing Adelie penguins.

Which state does the seedling do not rely on the cotyledon for growth. Explain how the seedling continues its growth
Explanation:
oviduct dip yucks dizzy icon sick issue sick
Answer:
seedling is a young sporophyte developing out of a plant embryo from a seed. Seedling development starts with seedling of the seed. A typical young seedling consists of three main parts: the radicle (embryonic root), the hypocotyl (embryonic shoot), and the cotyledons (seed leaves). The two classes of flowering plants (angiosperms) are distinguished by their numbers of seed leaves: monocotyledons (monocots) have one blade-shaped cotyledon, whereas dicotyledons (dicots) possess two round cotyledons. Gymnosperms are more varied. For example, pine seedlings have up to eight cotyledons. The seedlings of some flowering plants have no cotyledons at all. These are said to be acotyledons.The plumule is the part of a seed embryo that develops into the shoot bearing the first true leaves of a plant. In most seeds, for example the sunflower, the plumule is a small conical structure without any leaf structure. Growth of the plumule does not occur until the cotyledons have grown above ground. This is epigeal germination. However, in seeds such as the broad bean, a leaf structure is visible on the plumule in the seed. These seeds develop by the plumule growing up through the soil with the cotyledons remaining below the surface. This is known as hypogeal germination.

What is photosystem 1 and photosystem 2 and what do they do? What are the steps ?
P I and PII are proteic compounds present in the thylakoid membrane that contain about 300 chlorophyll molecules each.
Step IFirst of all light with a wavelength of 690nm is absorbed by P II. The light excites an electron that leads to the photolysis of water(H2O--->2H+ +2e- + 1/2O2). The two electrons released go into the electron transport chain. The second compound in electron transport chain is plastoquinone that is reduced when it accepts electrons then oxidised when it loses them to P I. The next two compounds are cytocromes that make hydrogen protons go inside the thylakoid when they recieve the electrons.(I will mention what happens to the H+ in the second step). The next compound in the electron transport chain is a compound that contains Fe and S. The electrons finally reach the last step: Reduction of NADP+ to NADPH+H+.
Step IIIn the second step is ATP synthesis. Hydrogen protons accumulate inside the thylakoid membrane. An electrochemical gradient is formed. The protons can leave the thylakoid according to this gradient through an enzyme.
When the protons flow through , it turns ADP into ATP.
To sumarize: the role of P II is O2 production through photolysis and ATP synthesis(indirectly) The role of P I is NADPH+H+ synthesis.
