<u>Answer:</u>
You try to pick up a shell in the water but it isn't where it appears to be is an example of diffraction
<u>Explanation:</u>
Diffraction refers to the light bending that happens as the light passes about the edge of some object. How much bending takes place is found by the size of wavelength of light relative to that of opening. If the opening is larger than the wavelength of light, then bending will not be noticeable.
Since, light gets diffracted due to water hence the shell kept inside the water appears to be at a different position than where it actually is
The correct answers are as follows:
1. NEURONS: Are specialized cells that generate and conduct electrical impulses throughout the body.
Neurons are the nerve cells that are the basic building block of the nervous system. Their major function is to transmit information round the body. There are different type of neurons that carry information to different part of the body. There are three basic part to every neuron, these are the dendrites, the cell body and the axon.
2. WHITE BLOOD CELLS: Are components of blood that help protect against pathogens and aid in blood clotting.
White blood cells refers to the cells of the immune system, which help the human body to fight against all manner of infection causing pathogens. White blood cells are produced in the bone marrow and they form about 1% of the total blood volume. A low white blood cell count is usually as a result of presence of infection.
3. EPITHELIAL CELLS: Are specialized cells that transport, protect, absorb, secrete and provide sensory signals.
Epithelial cells are specialized cells that are found in many organs. They have similar structural properties especially in term of arrangement and the cohesiveness among them. They are specialized cells for absorption, secretion and they can also act as barrier.
4. RED BLOOD CELLS: Are the component of the blood that carry oxygen throughout the body.
Red blood cells are the cellular component of the blood, which are responsible for transporting oxygen to every cells in the body. The cells carry fresh oxygen from the lungs and transport it to all parts of the body, they also collect carbon dioxide and transport it to the lung for breathing out. The red blood cells are manufacture in the bond marrow and the longest that a red blood cell can live is 120 days.
5. MUSCLE CELLS: Are elongated cells that have the ability to contract.
Muscle cells are made up of myosin and actin, which are protein filaments that slide past one another in order to produce contractions, which changes the length and shape of the cell. Muscles cells are largely responsible for maintaining and changing posture, locomotion and movement of internal organs. There are three basic types of muscles, they are skeletal, cardiac and smooth muscles.
Fish are cold-blooded or poikilothermic, meaning that their body temperatures vary with the surrounding temperature. During the cold of winter fish become less active. They find little pockets out of the way of fast moving water where they can stay still and conserve energy.
Answer:
I think its A) To process bacteria...
When a petal is plucked from a flower, it will not remain alive for very long. It will soon start to decompose.
Explanation:
To understand this, we need to go back to the act of plucking the flower as such from the plant. The moment a flower is plucked from a plant, it stops receiving any further nutrition from the plant. Whatever nutrients were present in the flower at the time of plucking it will continue to keep it alive and once those nutrients are used up, the flower will start to decompose.
In this case, since the petal is plucked from a flower which already was surviving on limited nutrients, it will decompose very quickly.
According to the characteristics of life, it cannot be considered dead at the time it's plucked. It <u>continues to live, but for a very brief time</u>.
