A = Smooth Endoplasmic Reticulum

B = Vacuole

C = Mitochondria (Plural)

D = Nucleolus

E = Cell Wall

Explanation:

This is obviously a plant cell. Animal cells do not have cell walls(E), and most animal cells will not have a vacuole(B). Smooth Endoplasmic Reticulum: This produces protiens (contains ribosomes) but when looked through a microscope, will appear to be smooth. The vacuole(B) is like a storage for the plant cell, and it helps support the plant cell. This is the reason why plants “droop” when you don’t water them for a long time. Mitochondia (Plural) processes nutrients for the cell. The nucleolus(D) covers the nucleus. It’s main function is to process RNA and combine it with proteins. The cell wall(E) helps support and protect the cell.

Explanation:

Let us go option by option :

1) Genes are located in chromosomes. TRUE

Chromosomes are in cell nucleus. A chromosome contains hundreds and thousands of genes. A normal have 23 pairs of chromosomes, and a total of 46.

2) Chromosomes are the in nucleus.

TRUE

Chromosome is structure found in nucleus of the cell. It is made up of protein and DNA.

3) A single Chromosome can contain hundreds of genes.

TRUE

single Chromosome can contain hundreds of tgenes.

4) All of the above

TRUE

As all the statements above are true. The correct option is 4.

Answer:

all of them are true

Explanation:

this is because chromosomes contain genetic materials and it is present in the nucleus.
Therefore, the correct option is 4) all of these are true

no problem

Answer:

1. Reuse things like cups, towels, cloths, etc.

Answer:

A 19

Explanation:

2 mole of KClO3 produces 3 mole of O3

2 : 3

1 : 3/2

12.61 : 3/2 × 12.61

12.61 : 18.9

12.61 mole of KClO3 produces 18.9mole of O2.

Answer:

The graphs are showing the difference in exo/endothermic reactions.

Explanation:

In an exothermic reaction, the reactants are higher than the products. There are more reactants and less products. This is the opposite of an endothermic reaction. In endothermic reaction, the reactants are lower than the products as shown in the graph. The activation energy looks about the same.

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Answer:

Is A- Carbon Dioxide

Explanation:

other air pollutants collect in the atmosphere and absorb sunlight and solar radiation that have bounced off the earth's surface.

Answer:

0.00302min⁻¹ = k

Explanation:

In a first order reaction the concentration of the reactant decrease following the equation:

ln[A] = -kt + ln[A]₀

ln [A] / [A]₀ = -kt

Where [A] represents actual and initial concentration of the reactant, k rate constant and t time.

As the reactant drop to 18.0% of its initial concentration  [A] / [A]₀ = 0.18

And time = 56.7min:

ln [A] / [A]₀ = -kt

ln 0.18 = -k*56.7min

-1.715 / 56.7min = -k

Temperature, humidity, pressure, gravity, altitude, vibration, stress, strain, and illumination are among the variables.

Accuracy is the capacity of an instrument to measure the precise value. In other words, it refers to how closely the measured value resembles a reference or genuine value. Small readings can be taken to increase accuracy. The calculation's inaccuracy is decreased by the little reading.

The precision of a material is defined as the degree to which two or more measurements agree with one another. It is incredibly precise but not always accurate to measure something if you weigh it five times and get 3.2 kg each time. Accuracy is not necessary for precision.

The degree to which a measurement is accurate in relation to its real value. The degree to which the same results are produced by repeated measurements under the same circumstances is known as precision.

Therefore, temperature, humidity, pressure, gravity, altitude, vibration, stress, strain, and illumination are among the variables.

The shell represents the crust. The hydrosphere and the biosphere interact with this layer.

Explanation:

The layers, which make up the hard-boiled egg are comparable to the layers, which make up the Earth. Flowing water in the hydrosphere weathers rocks into small pieces, which are eroded and deposited to different locations on Earth.

Answer:spectrum

Explanation:

Let's start with the basics. The electromagnetic spectrum is a range of different types of electromagnetic waves. These waves have different wavelengths and frequencies, and they include things like radio waves, microwaves, infrared radiation, visible light, ultraviolet radiation, X-rays, and gamma rays. But here's the thing: not all of these waves are visible to the human eye.

So, which ones are visible? You guessed it – it's the visible light that we're interested in. Visible light is the part of the electromagnetic spectrum that we can see. It's made up of different colors, including red, orange, yellow, green, blue, indigo, and violet. When all of these colors are combined, they make white light.

But what about the other types of electromagnetic waves? Well, they are not visible to the human eye. For example, radio waves are used to transmit radio and television signals, but we can't see them. Microwaves are used for cooking food, but we can't see them either. Infrared radiation is what we feel as heat, but it's also not visible to us. Ultraviolet radiation can cause sunburn, but we can't see it either. X-rays and gamma rays are used in medical imaging and radiation therapy, but we can't see them with our eyes.

So, in summary, visible light is the only part of the electromagnetic spectrum that we can see with our eyes. All of the other types of electromagnetic waves, including radio waves, microwaves, infrared radiation, ultraviolet radiation, X-rays, and gamma rays, are not visible to the human eye. Isn't that amazing?

Fire stick Managing the environment through farming Aboriginal people  routinely burned grass to minimise fuel and promote new growth in order to attract grazing animals for hunting.

Among the various ways that agriculture has an impact on society are the provision of food, habitat, and employment opportunities; the provision of raw materials for food and other goods; and the development of robust economies through commerce.

A large number of species use pasture and crops as both a habitat and a source of food, making up around 50% of the planet's livable land. Sustainable management of agricultural operations has the potential to safeguard watersheds, restore significant habitats, and improve the quality of the soil and water supply.
