¿Podrá la planta producir frutos dentro de una caja oscura?
Answer:
No.
Explicación:
No, la planta no podrá dar fruto en una caja oscura porque para su crecimiento la planta necesita luz solar y sin luz solar no se produce fotosíntesis y sabemos que en el proceso de fotosíntesis, las plantas preparan su propia comida y crecen en tamaño. Este proceso de fotosíntesis solo ocurre en presencia de luz solar, por lo que en la oscuridad no hay luz solar, por lo que no se produce la fotosíntesis y la planta morirá.
What is the function of insulin?
Insulin is a hormone produced in the pancreas (gut) .
Function:
Insulin regulates the amount of glucose in the blood. The lack of insulin causes a form of diabetes.
Explanation:
Insulin is a hormone secreted by the beta- cells of Islets of Langerhans of pancreas.
Its function is to regulate blood sugar level in the body by decreasing it. If the sugar level of the blood increases, it is detected by the pancreatic cells and it releases insulin.

1. Which of the following is NOT a result of convection current? a) The air in a room is cooled by an air conditioner b) Wind blows towards the beach from the sea. c) The water in a kettle is heated and boils d) The wax covering an iron rod melts when the rod is heated.
Answer:
its D
Explanation:
because conduction happens through solids and the others are obviously conventional current
The wax covering an iron rod melts when the rod is heated ( D ) is not a result of convection current
Convection is the transfer of heat energy from an area of higher concentration to an area of lower concentration and it occurs in fluids and gases. while conduction is the transfer of heat energy from one object to another through the direct contact of the objects and this occurs between solids.
The transfer of heat from the heated rod to the wax covering occurs because of the direct contact the wax has with the heated rod therefore it is conduction and not a convection current.
Hence we can conclude that The wax covering an iron rod melts when the rod is heated is not a result of convection current

You recently identified a molecule that you believe is a primary messenger for a signal transduction mechanism. All you know about this ligand is that it is hydrophilic. Where would you expect to find initial interaction of the molecule with its receptor
Answer:
Receptor on the outer cell surface.
Explanation:
Hydrophilic signal molecules are the water soluble molecules, they are polar polar and therefore cannot pass through the non-polar center of the plasma membrane without any mediator. Water-soluble ligands bind to the extracellular domain of cell surface receptors. Signal molecules cannot enter the cell and thus plasma membrane receptor is required. Plasma membrane receptor form an important class of integral membrane proteins that transmit signals from the extracellular space into the cytoplasm. This group of signal molecules is quite diverse and most are based on amino acids. In some cases the unmodified amino acid is the signal molecule, in others the amino acid is modified into a derivative and in still others amino acids are combined into peptides and proteins.
What phase of mitosis is shown in the diagram below?
O A. Prophase
O B. Telophase
O C. Metaphase
O D. Anaphase
Answer:
B. "Telophase"
Explanation:
The chromosomes are at opposite poles, the nuclear envelope is reforming and the cell is getting ready to divide, the next phase is Cytokinesis.
Hope this helped.
Telophase is a phase of mitosis as shown in the diagram below. The correct option is (B).
Telophase is a stage of mitosis, the procedure by which eukaryotic cells divide. The splitting of the cytoplasm into two daughter cells during cytokinesis, the last stage of mitosis, follows it.
There are several significant events that occur during telophase:
Chromosome decondensation: The chromosomes that were tightly curled and compressed during metaphase and anaphase begin to uncoil. As a result, the genetic material is able to spread and become less obvious under a microscope.
Nuclear envelope formation: Around the divided sets of chromosomes, the nuclear envelope, which had fragmented during prophase and metaphase, starts to reconstruct.
Hence, telophase is a phase of mitosis as shown in the diagram below. The correct option is (B).

2. A mirror works by __________the light that hits
Answer:
1.A _shadow_ is formed when an _ transparent _ object blocks the path of light
2. A mirror works by _reflecting_the light that hits
Explanation:
1. A shadow is made when an object blocks light. The object must be opaque or translucent to make a shadow. A transparent object will not make any shadow, as light will pass straight through it.
2.When photons — rays of light — coming from an object (your smiling face, for example) strike the smooth surface of a mirror, they bounce back at the same angle. Your eyes see these reflected photons as a mirror image.

Growth media are used to grow microorganisms in a lab setting. Some media are liquids; others are more solid or gel-like. A growth medium provides nutrients, including water, various salts, a source of carbon (like glucose), and a source of nitrogen and amino acids (like yeast extract) so microorganisms can grow and reproduce. Ingredients in a growth medium can be modified to grow unique types of microorganisms. For example; _____is a general-purpose, non-selective growth media, _____is a non selective, enriched growth medium with red blood cells that have been lysed by heat, Columbia Nalidixic Acid (CNA) and _____are selective agar for Gram positive organisms and ______agar is a selective agar for Gram negative organisms, Mannitol salt agar MSA is a commonly used selective and differential growth medium that encourages the growth of bacteria that ferments mannitol, and _____is an example of a liquid that supports growth of a variety of organisms.
Answer:
Growth media are used to grow microorganisms in a lab setting. Some media are liquids; others are more solid or gel-like. A growth medium provides nutrients, including water, various salts, a source of carbon (like glucose), and a source of nitrogen and amino acids (like yeast extract) so microorganisms can grow and reproduce. Ingredients in a growth medium can be modified to grow unique types of microorganisms. For example; Nutrient agar is a general-purpose, non-selective growth media, Chocolate agar is a non selective, enriched growth medium with red blood cells that have been lysed by heat, Columbia Nalidixic Acid (CNA) and Mannitol Salt agar are selective agar for Gram positive organisms and MacConkey agar is a selective agar for Gram negative organisms, Mannitol salt agar MSA is a commonly used selective and differential growth medium that encourages the growth of bacteria that ferments mannitol, Nutrient broth is an example of a liquid that supports growth of a variety of organisms.
Explanation:
Growth media are classified based on their composition as:
1. General Purpose Media: These type of media support the growth of non-fastidious organisms, that do not require special nutrients for growth, and they also serve as a base for certain modified media. An example is the nutrient agar
2. enriched media: these media, like the name implies, is one that has been modified by the addition of special growth factors and nutrients called enrichment. An example is chocolate agar where lysed blood is added to nutrient base agar, when the blood cells are lysed slowly at 80°C, nicotinamide adenine dinucleotide (factor V or NAD) and hemin (factor X), are released into the medium, and these support growth of certain fastidious organisms like Haemophilus influenza bacteria.
3. Selective media: These kinds of media contain substances that support the growth of certain organisms while in turn preventing the growth of others due to the presence of certain inhibitory factors. Examples are: Mannitol Salt Agar, which supports growth of Gram-positive organisms and MacConkey agar, which supports the growth of Gram-positive organisms
4. Non Selective media: These type of media have no biases against the growth of certain organisms, that is, they do not contain certain inhibitory factors that impede the growth of certain organisms.
5. Differential media: These media contain chromogenic agents that change colour and helps to differentiate one organism from the other, making for ease of identification especially for organisms with similar properties.
Finally, a broth is a growth medium that fo not contain agar, hence, it is liquid and not solid.
