Answer: See explanation
Explanation:
1. Question: What have been the patient's symptoms?
The patient's symptoms are slight dry cough and runny nose.
2. Question: When did the patient being to exhibit symptoms?
The patient begin to exhibit symptoms when she returned home after visiting her grandparents in late 2010.
3. Question: Has the patient traveled recently?
Yes. She has. She went to visit her grandparents.
4. Question: Has anyone else in the family traveled recently?
Yes. Her parents.
5. Question: Has the patient experienced any other recent illness?
No. She hasn't. This wasn't stated above.
6. Question: Is the patient up to date with vaccinations for her age (6 months)?
No. She isn't. It was stated that when the child began having a dry cough and running nose, her mother thought that it was a common cold and thereby choose not to seek medical attention for the baby. This is wrong and shows that she isn't up to date with vaccinations. Even if it's a cold, there should be proper medical attention given to her.
B. a female egg cell and a male sperm cell each develop separately into an offspring that is different from both parents.
C. a female egg cell and a male sperm cell each develop separately into an offspring that is identical to its parent.
D. a female egg cell combines with a male sperm cell to make an offspring that is different from both parents.
Answer:
D- a female egg cell combines with a male sperm cell to make an offspring that is different from both parents
Explanation:
The four symptoms in the human body caused due to air pollution are:
•Itching and redness in eyes: This is a very common symptom easily seen in the people as an effect of air pollution. Redness and itching is caused due to inflammation in eyes.
•Coughing: Coughing is also caused due to inflammation in the bronchi. The mucosa secreted encounters some foreign materials and as a result of this coughing starts.
•Sneezing: The nasal passage has some mucosal secretion which when encounters the dust particles starts sneezing.
•Nausea: Some people feel nausea due to gases that causes air pollution
The four different symptoms in the human body that may be caused by air pollution are coughing, sneezing, nausea, redness and itching in eyes.
Further Explanation:
The addition of any harmful substance or gases mainly referred as pollutant into the air so as to change the natural composition of air is called air pollution. In this various solid, gases, or liquid particles releases in the environment. These pollutants are release into environment in the high concentration that affect health, aesthetic or economic effects.

Spastic paralysis typically involves the upper motor neurons of the central nervous system. Damage to these neurons causes symptoms such as muscle stiffness and contraction. Conditions such as multiple sclerosis, cerebral palsy, and spinal cord injury can lead to spastic paralysis.
Spastic paralysis is a medical condition typically involving the upper motor neurons of the central nervous system. These neurons play a crucial role in controlling the activities of lower motor neurons, which are directly responsible for muscle movement. When there is damage or involvement of these upper motor neurons, it can lead to a condition known as spastic paralysis. This condition is characterized by muscle stiffness and contraction, often leading to impaired movement and coordination.
Some examples of conditions that can cause spastic paralysis include multiple sclerosis, cerebral palsy, and spinal cord injury. Treatment often involves managing symptoms and may include physical therapy, medications to reduce muscle spasticity, and sometimes surgery.

Answer:
Facilitated diffusion
Explanation:
Oxidative phosphorylation, involving the Electron transport chain and Chemiosmosis is the third stage of cellular respiration. The main purpose of the ETC is to build an electrochemical (electrical and concentration) gradient across the inner mitochondrial membrane. It does this by using energy to pump protons (H+ ions) from the matrix to the inter-membrane space of the mitochondria.
Facilitated diffusion, also known as passive transport through channels, is a form of facilitated transport involving a passive movement of molecules along their concentration gradient, through channels called membrane proteins.
During Chemiosmosis of Oxidative phosphorylation, protons (H+) flow back down their concentration gradient (from inter-membrane space to matrix) due to the chemiosmotic gradient that has been formed in ETC. However, hydrogen ions (H+) cannot pass through the inner mitochondrial membrane except through an enzyme (protein) found in the inner mitochondrial membrane called ATP synthase. This protein acts as a machine powered by the force of the H+ diffusing through it, down an electrochemical gradient. This movement of H+ via ATP synthase further catalyzes the conversion of ADP to ATP.
It is an example of facilitated diffusion because H+ ions are diffusing across the inner mitochondrial membrane (from inter-membrane space to matrix) via a protein channel or membrane protein called ATP synthase.
The movement of H+ through the ATP synthase is best described as an example of chemiosmosis, which involves the movement of ions across a membrane through a specialized protein channel to generate ATP.
The movement of H+ through the ATP synthase is best described as an example of chemiosmosis. Chemiosmosis is the movement of ions across a membrane down their electrochemical gradient through a specialized protein channel like the ATP synthase. This process generates ATP, the energy currency of the cell.
