Answer:
In passive transport, molecules move with the concentraction gradient.
Explanation:
If molecules moved against it would be active transport.
Passive transportation has been defined as the mode of molecule movement across the semi-permeable membrane. "In passive transport, molecules move down the concentration gradient."
What is passive transport?Passive transport has been the mode of movement of the ions and molecules from the exterior and interior of the cell through the plasma membrane. This mode of transportation has been characterized by the movement of the ions from the region of a higher electrochemical gradient.
The ions tend to move towards the region that lacks the electrochemical gradient, hence it is a movement in the direction of the lower concentration. The solute particles do not external source of energy to drive the movement from higher concentration areas.
It is a type of diffusion that uses the law of Thermodynamics to move the ions up and down the cell concentration. The movement of the oxygen gas in the body cells is an example of passive transportation.
Therefore, the ions move down the concentration gradient in the passive transport.

If a woman has both alleles in her body cells, what will her eggs contain?
If a woman has both alleles in her body cells, then her eggs will contain only one of the alleles. This is because during the formation of eggs, a process called meiosis occurs, which randomly separates and distributes the alleles to the daughter cells. Therefore, each egg will contain one of the two alleles that the woman carries.
What is allele ?An allele is a variant form of a gene that is responsible for the expression of a particular trait or characteristic of an organism.
If a woman has both alleles in her body cells, it means that she is heterozygous for that particular gene. This means that she has two different versions (alleles) of the gene, one inherited from each parent.
During the process of meiosis, which produces eggs, the two alleles will segregate, meaning that each egg will receive only one allele.
The allele that ends up in each egg is random and depends on the particular orientation of chromosomes during meiosis.
So, the woman's eggs will each contain one of the two alleles she carries, and there is a 50% chance that each egg will contain either allele.

A food handler reports to work with obvious yellowing of the eyes and skin. What should the person be checked for?
Answer:
Hepatitis A
Explanation:
Hepatitis A refers to a liver disease or infection that results in mild to severe illness in humans and it is typically caused by the Hepatitis A Virus (HAV).
Generally, the main cause of Hepatitis A is as a result of the ingestion of food or consumption of water that has been contaminated by the Hepatitis A Virus (HAV) or getting in direct contact with fluids from an infected person.
Some of the symptoms of Hepatitis A are loss of appetite, feverish conditions, itching, nausea, fatigue, diarrhea, dark-colored urine, malaise, abdominal pains, yellowing of white portions of the eyes and skin (jaundice).
Hence, if a food handler reports to work with obvious yellowing of the eyes and skin. The sickness or illness that the food handler should be checked for as an adult is Hepatitis A.
Hepatitis A is a viral infection, which affects the liver. The person with obvious yellowing of eye and skin should be checked for Hepatitis A.
Hepatitis A is a viral infection caused by the Hepatovirus A. The virus affects the liver, which may lead to mild to severe illness in the patient. The disease is caused by the consumption of contaminated food and water, personal contact with the infected person, and using used drugs with other persons.
Some of the symptoms of Hepatitis A are:

Which organelle that plays a central role in the transport of new molecules from inside to outside the cell?
Answer:
The Golgi apparatus plays a central role in molecular transport after biosynthesis.
Explanation:
Transcription occurs in the nucleus during protein synthesis, followed by translation inside ribosomes. Then, new molecules join the endoplasmic reticulum to be folded and modified. In the Golgi, they are tagged and separated into lysosomes for export outside the cell.
The Golgi system comprises of several regions known as cisternae; they act as independent microenvironments where products requiring their own unique conditions are converted into new, stable biomolecules.

Binding of ________________ to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.
Answer:
Binding of ACh (acetylcholine) to receptors (ligand-gated) on the sarcolemma at the neuromuscular junction is vital for depolarization of the muscle fiber.
Explanation:
It allows acetylcholine to be released into this synapse when an action potential hits a neuromuscular junction. Acetylcholine attaches to the nicotinic receptors localized on the post-synaptic membrane of the muscle fibre's motor end plate, a specialized region.
Hence , the answer is ACh (acetylcholine) .

Imagine that a biological anthropologist 10,000 years in the future is examining our fossil remains. The anthropologist notices that humans have broad incisors and molars with rounded cusps. How do you think the anthropologist would interpret these traits---what diet would these traits indicate
Answer:
They were frugivores
Explanation:
Frugivores are animals that mainly eat raw fruits, vegetables, roots, seeds, shoots, etc. Frugivores need to eat diverse fruits and succulent fruit-like vegetables to fulfill their nutritional requirements, although they can supplement this diet with flowers, nectar, small insects, etc. Among their adaptations for fruit consumption, frugivore teeth are clearly distinct, having broad incisors to peel tough fruit rinds. Moreover, these animals generally have long small intestines to digest the fruit.
