if an earthworm is 18mm long and is photographed and the picture is magnified 2.5x how long will it be in the picture?

Answers

Answer:

The earthworm will be 45 mm long in the picture

Explanation:

From the problem, we can take the original size of the earthworm to be 18mm.

Magnification  can be obtained using the formula:

magnification = observed size/ original size.

Recall, we are given that the magnification is 2.5.

Hence, can evaluate the size in the picture to be

2.5 X 18mm = 45mm

List all six stages of the sensory pathway when an animal responds to information about its environment.

Answers

Explanation:

There basically four stages of sensory pathway when an animal responds to information about its environment.

and these stages of pathway are Reception,  transduction, transmission, and perception.

The sensory receptors are commonly described as specialised neurons found in sense organs that helps detect and respond to stimuli. The six stages of the sensory pathway which an animal responds to information about its environment are:

Reception: This falla under sensation. It is simply a type of sensory receptors detect that stimulus is present.Transduction: This also falls under sensation. It is a type of sensory receptors whose work is mainly to convert stimulus energy into electrochemical energy.Transmission: This falls under sensation. It is when neural impulses leave sensory organs and moves to the brain.selection: This falls under perception. It acts as detectors that filter the stimuli by responding to particular features of a stimulus while also ignoring the rest.Organisation: This falls under perception: It is known to organise the characteristics of sensory stimuli in a meaningful manner. Interpretation: This Fall also under perception. It is known to give meaning to sensory stimuli.

Sensation is simply regarded as a physiological process that uses sensory receptors in detecting and responding to stimuli.

Perception is referred to as the mental work of organising and interpreting sensory stimuli, making it meaningful.

how does shell color work to protect the egg from sunlight?

Answers

Answer:

Birds that live in cool climates lay darker eggs, as darker colors absorb more heat from the sunlight

Birds that live in hotter climates lay lighter eggs to prevent the egg from overheating.

The pigmentation acts to thermo-regulate the internal temperature of the egg, acting as a buffer between the embryo and the outside world. It does this by preventing overheating of the egg, through reflecting the sunlight off the pigmentation, rather than allowing it to be absorbed through the shell

Or else the food can be used up by plants to carry out their metabolic activities ( activities at cellular level which keeps the plant alive ) like cellular respiration

Answer:

The food that is prepared by the plant is utilized for its metabolic processes, the excess food is stored in the form of starch, in the plants. ... The plants prepare starch by a process of photosynthesis with the sunlight along with "water and carbon dioxide

The food produced by the plants is in the form of sugar and the extra sugar produced is changed to starch and is stored in different parts of the plant such as in roots, stems, leaves, fruits and flowers.

For each of the following minerals, say what properties of the material make it important in carrying out it's particular function.
a. tar roads
b. iron bulgar bars
c. plastic furniture
d. metal jewellery
e. clay for building
f. cotton clothing

Answers

Answer:

1. Tar Roads: The qualities of Tar that makes it ideal for road construction are:

The tar-like material that is used for road construction is a combination  (emulsion) of water and liquid asphalt. It serves the purpose of permeating and closing up small lacerations in the existing pavement.

When the emulsion sticks to the "gravel" it reduces the potential for vehicles to skid on the road thus enhancing safety. The "gravel-like" emulsion is applied by rolling and sweeping.

Qualities of Tar are:

Adhesive: its the ability to stick to surfaces including materials such as gravel which it holds together makes it great for road construction;Waterproof: It is not water-soluble. Hence is not easily susceptible to the effects of running water. Resistant to High Temperature: The melting point of Tar is 54 degrees centigrade. The ground can heat up to 45 degrees celsius thus making Tar perfect for road construction as it can remain rigid even in the worst temperatures.

2. Iron Burglar Bars

Steel bars are made from iron. The qualities of steel which make it perfect for securing places and things are:

Strength; This is the ability to withstand breakage and or destruction.  Toughness: Steel is very tough and can not easily bend or break under static loads. Weldability: Most steel bars are actually welded together. Without this ability, steel probably would be useless as a material that can be used for protectionDurability: The only factor that degrades steel is rust. Rust happens when steel is exposed to oxygen which can be found in air and water.

3.) Plastic Furniture

The primary qualities of plastic that make them suitable for furniture are:

Chemical stability: It does not rust or degrade when exposed to weather elements such as oxygen, water, etc. Good impact resistance: Depending on its thickness, plastic can bear a lot of weight and can take a lot of impact without deforming or breaking Good transparency and wear resistance: Plastic can be made transparent. This quality is essential for aesthetic purposes and hence can be used for various kinds of good-looking furniture. As furniture, its surface does not come off like hence it's durability.Low thermal conductivity: This means that it can bear heat without transmitting it easily.  Ability to General formability, good coloring, low processing cost.

4) Metal Jewellery

One of the best metals for jewelery is Tungsten. This is so because it is more durable and stronger than any other kind of material that can be used for jewelery purposes. It is about ten times harder than 18K gold and about four times harder than titanium. Other materials that can be used are:

titaniumstainless steel and cobalt

5) Clay

In it's raw form, clay used for building might not be the best idea as it susceptible to water absorption and hence deformation which generally leads to a collapse of the structure. However, it becomes an excellent material of choice after it has been hardened into brick.

Brick is preferred in construction due to the following qualities:

hardnessHigh Compressive strength, Low Water AbsorptionFrost resistanceFireproofGreat Insulation

6) Cotton is usually preferred as the material of choice for most kinds of clothing due to the following qualities:

Softness. The cotton plant is soft and fluffy and results in a fabric often retains that soft feel. Durability: Its molecular structure makes it able to last very long. Absorbency: it is able to absorb moisture/water. Hence making it more comfortable than synthetic materials   High Dye Tolerance: Ability to hold dye well is an indespensable quality of a good fabric. You don't want to have a fabric whose colours are quick to fade. Breathability: This reduces is very important especially during summer or when the weather or environment is very hot.

Cheers

The tar is roads that have quantities to make them deal with the construction. The liquid is a mix of asphalt and can be adhesive and waterproof.

The iron bars are used for securing the place and things. plastic furniture is used to make suitable furniture and is used for chemical stability etc. The metal jeweler is of titanium, cobalt and stainless steel

what three phases of the cell cycle are considered interphase

Answers

Answer:

The cell cycle has three phases that must occur before mitosis, or cell division, happens. These three phases are collectively known as interphase. They are G1, S, and G2. The G stands for gap and the S stands for synthesis.

Explanation:

The three phases of the cell cycle that are considered interphase include G1, S phase and G2.

The cell cycle can be divided into the interphase and mitotic (M) phases.

The interphase can in turn be divided into a Growth G1 phase, synthesis (S) phase and Growth G2 phase.

The synthesis of the genetic material (DNA) occurs in the S phase, whereas in G1 and G2 the cell synthesizes all materials required to enter into cell division.

In conclusion, the three phases of the cell cycle that are considered interphase include G1, S phase and G2.
