What are the 5 components of homeostasis?

Answers

Answer 1

The primary components responsible for the maintenance of homeostasis can be categorized as stimulus, receptor, control center, effector and feedback mechanism.

Change

Changes occur constantly in and around the cells of living systems. A change is anything that requires a cell to react, such as a change in temperature, pressure or chemical composition inside or surrounding the cell.

Receptor :Once a change occurs, it’s the receptors job to detect the change and alert the proper control center to counteract it, returning the cell and the overall system to a balanced state -- homeostasis.

Control Center

As the control center receives impulses from its remote receptors, it sends commands to the effector to counteract the change in the environment. Using the same example, the medulla oblongata commands the effector -- the heart in this case -- to slow its pulse. Control centers are located in the brain.

Effector

The effector acts on the impulses from its specific command center, counteracting the change and returning the internal and external cell environment to a balanced state. Effectors are the physical change agents such as the heart, organs and fluids of the body -- the workhorses of homeostasis.

an electron moves with a speed of 2.5×107 m/s in the directions shown in (figure 1) and (figure 2) below. a 0.60 t magnetic field points in the positive x-direction.

Answers

The force acting on an electron with a speed of \(2.5x10^7 m/s\) moving in a magnetic field of \(0.60 T\) pointing in the positive x-direction is \(3.0 x 10^-^1^7 N\)

When an electron is moving with a velocity v in a magnetic field B, a force F is exerted on the electron. This force is given by the formula: \(F = qvBsin\theta\) where q is the charge of the electron, v is the velocity of the electron, B is the strength of the magnetic field, and θ is the angle between the direction of motion of the electron and the magnetic field.

In this case, the electron is moving in a magnetic field of 0.60 T pointing in the positive x-direction, so θ = 90° and sinθ = 1.

Plugging in the given values, we get:

\(F = (1.6 x 10^-^1^9 C) (2.5 x 10^7 m/s) (0.60 T) (1)\)

\(= 3.0 x 10^-^1^7 N\)

Therefore, the force acting on the electron is \(3.0 x 10^-^1^7 N\)

blank is stored in a fossil fuel, and released in the form of kinetic energy when
burned.

Answers

Chemical energy is stored in a fossil fuel and released in the form of kinetic energy when burned.

Fossil fuels, such as coal, oil, and natural gas, are derived from the remains of ancient plants and organisms that were subjected to high pressure and heat over millions of years.

These fuels contain energy-rich hydrocarbon compounds, primarily made up of carbon and hydrogen atoms. When fossil fuels are burned, the combustion process breaks down these hydrocarbons, releasing stored chemical energy.

This energy is then converted into heat and kinetic energy, resulting in the production of heat, light, and mechanical energy, which can be harnessed for various purposes, such as generating electricity or powering vehicles.

The chloroplast is the organelle that allows some living things to engage in photosynthesis. While not present in fungus or protozoa, it is present in algae.

What role does photosynthesis play in chloroplasts?

Chlorophyll, a pigment that absorbs light and gives plants their green hue, is found within the thylakoid membranes of the chloroplast. Chlorophyll absorbs energy from blue- and red-light waves and reflects green-light waves during photosynthesis, giving the plant its characteristic green color.

What serves the chloroplast?

Plant development and crop productivity are supported by the energy that chloroplasts produce through photosynthesis and oxygen-release mechanisms. Therefore, chloroplasts are in charge of producing active substances such amino acids, phytohormones, nucleotides, vitamins, lipids, and secondary metabolites.

A student was observing slides of cell division. In one of the slides, he noticed loosely coiled chromatin depicting DNA duplication. Which phase of the cell cycle could it be?

A.
S phase
B.
Metaphase
C.
M phase

Answers

Answer:

A. S phase

Explanation:

The cell cycle involves all the series of division events that occurs to an organism. Cell division, which can be meiosis or mitosis, involves two main stages viz: Interphase and M phase.

Interphase describes the resting stage of the cell i.e. when the cell is not dividing. The cell uses this time to prepare itself for the next round of division. Interphase stage further consists of three main phases viz: G1, S and G2 phases.

In the S phase or synthesis phase of Interphase, the cell duplicates its genetic material (DNA). Hence, an onion cell observed by a student to have loosely coiled chromatin depicting DNA duplication is in the S-PHASE.

Photosynthesis

Photosynthesis is a biological process whereby green plants are able to make use of inorganic materials such as carbon dioxide and water to synthesize carbohydrates in the presence of solar radiation.

The carbon dioxide diffuses through the tissues of green plants such as leaves or stems while the water is conducted into the body of the plant from the root. Solar energy is utilized to drive the process while oxygen gas is liberated as a by-product. The overall equation of the reaction is as follows:

\(6CO_2 + 6H_2O -- > C_6H_{12}O_6 + 6O_2\)

) You've processed two samples using an LDPSA and the grain size histograms are below. Describe the two samples in terms of predominant grain size (sand, silt, clay), sorting, and maturity. Based on this information, which one came from a beach and which one came from a river, and why?

Answers

Sample 1 likely came from a beach due to its dominance of sand, moderate sorting, and absence of silt and clay. Sample 2 likely originated from a river due to its fine-grained nature, poor sorting, and inclusion of silt and clay fractions.

Sample 1: The histogram for Sample 1 shows a predominant grain size in the sand range, with minimal representation of silt and clay. The distribution appears moderately sorted, with a narrow peak in the sand fraction. This suggests that Sample 1 likely originated from a beach environment. The dominance of sand indicates a coarse-grained sediment, typically found on beaches due to wave action. The moderate sorting implies moderate energy conditions at the beach, allowing for some sorting but not complete separation of grain sizes. The absence of significant silt and clay fractions suggests limited transportation and deposition in a marine setting.

Sample 2: The histogram for Sample 2 exhibits a broader distribution of grain sizes, including significant representation of silt and clay fractions. This indicates a fine-grained sediment. The distribution is poorly sorted, with no distinct peak or dominant grain size. These characteristics suggest Sample 2 likely originated from a river environment. Rivers transport and deposit sediments from various sources, resulting in a mixture of grain sizes. The presence of silt and clay suggests longer transportation distances and lower energy conditions compared to beach environments. Poor sorting indicates minimal sorting and mixing of sediments, as seen in river systems.
