Faulty CFTR gene and CFTR proteins not being produced or function properly.
These actions can inhibit the effectiveness on the cell membrane.
Answer:
C
Explanation:
carbon dioxide +water + sunlight -->glucose+ oxygen
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.
Answer:
They had a large brain size of 700 to 1,250 cubic centimeters and large brow ridges with a nuchal torus at the back of the skull.
Explanation:
<em>Homo erectus</em> was one of the species of the homo genus which were considered the first species to have the human-like the feature that is they can stand upright on two legs and were therefore referred to as the upright man.
They showed many evolutionary advances over their ancestors called Homo Australopithecus as they showed encephalization. Encephalization refers to the increase in the size of the brain due to more neuronal complexity and neurogenesis and they possessed about 750 to 1250 cc brain size.
They showed torus at the back of the muscle which can hold the muscle of the neck and also showed the large brow ridges in the front of the skull.
Thus, the selected option is the correct answer.
