Which describes one thing that happens during thermoregulation when a sensor recognizes that a person's temperature is 35 degrees Celsius?
A. Hair on the body lies flat against the skin.
B. Blood vessels under the skin expand.
C. Sweat glands are turned on.
D. Muscles under the skin make body hair stand on end.

Answers

Answer 1

Thermoregulation:  D. Muscles under the skin make body hair stand on end.

Why hairs of skin stand during thermoregulation?

Thermoregulation means maintaining constant body temperature of 37 degrees Celsius. Through a number of physical mechanisms, the human body keeps its temperature at roughly 98.6°F (37°C). Shivering to increase body temperature, sweating to decrease it, and constricting or relaxing blood vessels to change blood flow are a few examples. An individual may overheat and develop hyperthermia if they are unable to control their body temperature. The inverse is also true: Hypothermia will result if the core temperature drops below a safe level. Both ailments have the potential to be fatal.

The skin's hairs aid in controlling body temperature. Each hair's erector muscle makes them stand straight when they're cold. Insulates by trapping a layer of warm air close to the skin.

The lagging strand runs in a   5’ to 3’ direction and is replicated  discontinuously.

Why a discontinuous or delayed tape?

The other strand, called delayed, is replicated discontinuously. In this case, the presence of Okazaki fragments is necessary, small pieces of DNA that will bind to form a new strand. - DNA is degraded by two types of enzymes.

The ends of a DNA strand are classified as 5' and 3', as they correspond to the carbon number of the pentose where the phosphate and hydroxyl (OH) group are located, which join in a phosphodiester bond.

Design an imaginary food web or describe a real one. Include at least 4 living organisms that interact in your ecosystem.

Answers

The trophic web is the interaction between different organisms in which there is energy transference. In the attached example, we consider plants, beetle, rabbit, frog, eagle, fox, mountainlion, and fungi.

What is the trophic web?

The trophic web is the interaction between different organisms involving transference of energy when some of them feed on the other ones.

The ones placed at lower levels pass energy to the ones at the higher levels.

Organisms at each level feed on the preceding one and become food for the next one.

• The first link corresponds to a producer organism -autotroph-.

• The following links are the consumers -heterotrophs- ⇒ herbivores and carnivores.

• The last links are the decomposers that degrade organic matter from dead organisms.

Because it is a web, all organisms are in equilibrium until a change occurs. When a sudden change affects any of the involved links, there can be a cascade effect on the web.

Any change in a link population size (increasing or decreasing) will affect the superior links and the immediately anterior link.

Example.

To make the trophic web, first, we need to have at least four links.

So first, let us list the organisms we are working with, and then define the position of each of the organisms on the web.

plants,beetle,rabbit,frog,fox,mountain lion, eagle,Fungi

Producer → this is the autotroph organism that takes energy from the sun or any other inorganic source → An example of this is any plant.

Consumers → heterotroph

Herbivores → These are the animals that feed on any part of the plants → These are the beetle and the rabbit

Carnivores → These are the animals that feed on herbivores → These are the frog, the fox, the eagle, and the mountain lion

Decomposer → detritivorous organisms that take energy from dead matter → Fungi

Trophic web,

Plants directly provide energy to the beetle and the rabbit

Plant >> Beetle and Rabbit

The eagle takes energy from the rabbit and the frog takes energy from the beetle.

Rabbit >> Eagle

Beetle >> Frog

The fox takes energy from the frog and from the rabbit

Frog and rabbit >> Fox

The Fox and the eagle transmit energy to the mountain lion.

Fox and Eagle >> Mountain lion

Fungi takes energy from dead organic matter

Plants, beetle, Rabbit, Fox, Eagle, Mountain lion >> Fungi

As a consequence of infection by a temperate bacteriophage such as lambda, the host cell:.

Answers

The host cell may lyse or may continue to divide and replicate both itself and the prophage.

What is the effect of temperate bacteriophage on a host cell?

Lytic cycle:

The infecting phage kills the host cell at the end of the lytic cycle, also known as a virulent infection, to create a large number of its own offspring. The phage genome immediately produces early proteins that degrade the host DNA after being injected into the host cell, enabling the phage to take over the cellular machinery.

The remaining proteins needed to construct fresh phage particles are subsequently synthesized by the phage using the host cell. The new genetic material is packed into the head while new daughter phage particles are built, and the heads and sheaths are created independently. In the course of this process, phage enzymes gradually weaken the host cells, which eventually burst, dispersing 100–200 additional phage progeny into the environment.

Lysogenic cycle:

The lysogenic cycle, also known as temperate or non-virulent infection, uses the host cell as a haven where it can survive in a latent state. It does not harm the host cell. After the phage DNA is injected into the host cell, it uses integrases encoded by the phage to integrate into the host genome, at which point it becomes known as a prophage.

The host cell divides for the duration that it is there and does not create the proteins necessary to make progeny, at which point the prophage genome is passively copied alongside the host genome. The bacterial hosts are typically somewhat unaffected by this procedure because the phage genome is typically quite tiny.

I understand the question you are looking for is this:

What kind of geological forces or events cause mountains to form? Using the Himalayan Mountains as an example, explain the process of mountain building that is caused by plate movement.

Answers

The Indian Plate and Eurasian Plate colliding caused the formation of the Himalayan Mountains and Tibetan Plateau.

When India and Tibet collided, the relatively light sedimentary and metamorphic rock that makes up the Indian subcontinent pushed against Tibet, driving it upwards, and creating a gigantic mountain fold instead of descending with the plate.

Where continental plates clash, mountains form. Each plate will not sag below the other because they are the same thickness and weight.

Instead, they give way and fold until the rocks are forced to take the shape of a mountain range. Mountains keep rising in height as the plates continue to collide.

As a result of the Indian Plate and Eurasian Plate colliding, the Himalayan Mountains and Tibetan Plateau were created.

A tonicity with a high concentration of solutes is said to be _________. hypertonic isotonic selectively permeable hypotonic

Pan~

Tonicity with a high concentration of solutes is said to be hypertonic.

Tonicity is the ability of an extracellular solution to allow the movement of water in and out of the cell by osmosis. The terms hypertonic, isotonic and hypotonic decide the movement of water into or out of the cell.

The hypertonic solution is a kind of solution which has a high concentration of solutes (salts, electrolytes). In Biology, a cell is said to be in a hypertonic solution if the outside solution has a high concentration of solutes than the inside the cytoplasm of the cell. In this situation, there will be a net flow of water out of the cell.

The hypotonic solution is a type of solution which has a low concentration of solute. ). In Biology, a cell is said to be in a hypotonic solution if the outside solution has less concentration of solutes than the inside the cytoplasm of the cell. In this situation, there will be a net flow of water into the cell.

Isotonic solution is one which has the same concentration of water and solutes as inside the cytoplasm of a cell. If a cell is placed in an isotonic solution, there is no net water movement.
