Mitochondria is a organelle which is full of energy. It sends to all parts of cell in the form of ATP.
What is mitochondria?The majority of the chemical energy required to drive a cell's metabolic operations is produced by mitochondria, which are membrane-bound cell organelles (mitochondrion, singular). Adenosine triphosphate, a tiny molecule, serves as a storage container for the chemical energy generated by the mitochondria (ATP).
Small chromosomes found in mitochondria are found there. In most cases, mitochondria and consequently mitochondrial DNA are exclusively passed down from the mother.
Organelles that are membrane-bound include mitochondria, however they are membrane-bound with two distinct membranes.

Answer: In cases like these usually we follow median effective dose .
The 50% that cause a response are considered highly reactive cases.
This number has common use as what a clinician or patient can expect for a drug effect.
Explanation:
Dose-response data are typically graphed with the dose or dose function (eg, log10 dose) on the x-axis and the measured effect (response) on the y-axis. Drug effects may be quantified at the level of molecule, cell, tissue, organ, organ system, or organism.
Dose-response, which involves the principles of pharmacokinetics and pharmacodynamics, determines the required dose and frequency as well as the therapeutic index for a drug in a population. The dose-response curve is the graphical representation of the relationship between the dose of a drug versus the effects that the drug exerts on the system tested, depicting the magnitude of the response of the organism, either therapeutic or toxic.
The response is measured within a range of concentration and often not measured at different times after the biological system is treated with the drug.

What is the function of the enzyme topoisomerase in DNA replication? (A) relieving strain in the DNA ahead of the replication fork caused by the untwisting of the double helix (B) elongating new DNA at a replication fork by adding nucleotides to the existing chain (C) reattaching the hydrogen bonds between the base pairs in the double helix (D) building RNA primers using the parental DNA strand as a template
Answers
The function of the enzyme topoisomerase in DNA replication is relieving strain in the DNA ahead of the replication fork caused by the untwisting of the double helix.
Nuclear enzymes known as topoisomerases are crucial for DNA replication, transcription, chromosome segregation, and recombination. These enzymes come in two main varieties; type I enzymes pass one or two DNA strands through the break before sealing it, whereas type II molecules cleave both DNA strands simultaneously and religate the double-strand break after passing another double strand through the break. By splitting, swiveling, and reconnecting DNA strands, a topoisomerase corrects "overwinding" before replication forks. This enzyme, to put it simply, stops the DNA double helix before the replication fork from becoming too wrapped as the DNA is opened up. Therefore, this enzyme stops DNA from supercoiling.

Energy requiring metabolic pathways that yield complex molecules from simpler precursors are: A) amphibolic. B) anabolic. C) autotrophic. D) catabolic. E) heterotrophic
Answers
Energy requiring metabolic pathways that yield complex molecules from simpler precursors are: anabolic. The correct option is (B).
Anabolic pathways are those metabolic pathways in which simple molecules are combined to form more complex molecules. These pathways require energy, usually in the form of ATP, to drive the chemical reactions that synthesize complex molecules from simpler precursors.
Anabolic pathways play an important role in building the macromolecules needed for cellular structures and functions, such as proteins, nucleic acids, and complex carbohydrates. These pathways are also involved in the storage of energy in the form of glycogen, lipids, and other complex molecules.
Examples of anabolic pathways include protein synthesis, DNA replication, and glycogen synthesis. These pathways are often linked to catabolic pathways, which break down complex molecules into simpler ones and release energy.
Together, anabolic and catabolic pathways maintain the balance of chemical reactions in the cell, allowing it to grow, divide, and carry out its functions.

¿de que manera el desarrollo cientifico y tecnologico repercute en la agricultura ecologica ,como parte de las condiciones para la propuesta de emprendimiento familiar?
Answers
Answer:
Los desarrollos científico-tecnológicos han impactado positivamente sobre los sistemas de agricultura ecológica y en última instancia también sobre la agricultura familiar
Explanation:
La agricultura ecológica refiere a los procedimientos de explotación agrícola basados en la utilización sustentable de los recursos de la tierra y los métodos de fertilización orgánica, respetando el ambiente natural y evitando el uso de compuestos químicos artificiales (como por ejemplo plaguicidas químicos) y de cultivos transgénicos. Por otra parte, la agricultura familiar refiere a un tipo de agricultura ecológica basado en la dirección y la administración familiar. La agricultura familiar es el sistema de agricultura predominante en regiones pobres de América Latina y el Caribe, representando aproximadamente el 80 % de la producción agrícola. De este modo, el desarrollo de métodos eficientes de agricultura/ecológica familiar resultan fundamentales para lograr la seguridad alimentaria en la región y también para mitigar los efectos negativos del cambio climático. En este contexto, diferentes avances científico-tecnológicos han impactado positivamente sobre el manejo, eficiencia y productividad de la agricultura familiar como sistema de cultivo no sólo sustentable sino también eficiente, entre los cuales se destacan el desarrollo de mini-invernaderos, variedades mejoradas obtenidas a través de técnicas de mejoramiento genético convencional (selección a campo), trampas artesanales para la captura de insectos plagas, etc. Diferentes tecnologías/metodologías como las anteriormente citadas han sido ajustadas y validadas a partir de procesos de experimentación participativa con el objetivo de estudiar cuales son las condiciones de la zona que mejor se adaptan al tipo de cultivo y de incrementar la productividad de sistemas de cultivos sustentables.
The primary difference between active transport and facilitated diffusion is that active transport is the only one in which
A) [S]high → [S]low.
B) transporter proteins are required.
C) [S]low → [S]high.
D) the concentration gradient provides the necessary energy for movement.
Answers
The correct answer is B) transporter proteins are required. Facilitated diffusion and active transport are both mechanisms for moving molecules across a membrane, but they differ in the energy requirements and the use of transporter proteins.
Facilitated diffusion relies on a concentration gradient and uses transporter proteins to move molecules from high to low concentration, but it does not require energy input. In contrast, active transport moves molecules against their concentration gradient, which requires energy input from ATP hydrolysis or other sources, and it always involves transporter proteins to facilitate movement.
Therefore, the key difference between the two processes is the requirement of transporter proteins for active transport.

The energy source is the concentration difference of hydrogen ions across the membrane. C. The energy source is a set of atp molecules that gather inside the thylakoid. D. There is no energy source; the process occurs without an energy input.
Answers
The energy source is the concentration difference of hydrogen ions across the membrane.
The photochemical and electron transport reactions of oxygenic photosynthesis occur at the thylakoid membrane. The lipid composition of the thylakoid membrane is highly conserved among oxygenic photosynthetic organisms, with two galactolipids, one sulfolipid, and one phospholipid.
The primary functions of thylakoids are to trap light energy and convert it into chemical energy forms such as ATP and NADPH. Water is oxidized and oxygen is released during this process. Inside chloroplasts and cyanobacteria, thylakoids are membrane-bound compartments. They are the site of photosynthesis's light-dependent reactions.
