The movement of food through the esophagus is called peristalsis.
What is the buccal cavity?The mouth is what we generally call the buccal cavity. It is an opening that contains the teeth and the tongue. The tongue plays the important role of serving as the organ of taste while the teeth serves to marsh food. It is the white strong structure that occurs in the mouth that enables is to masticate our food. Also in the mouth we have the salivary gland which plays the role of secreting the saliva and we know that the saliva contains from enzymes that makes it possible for the digestion of food to commence at the moth. It the follows that the buccal cavity is made up of the teeth, tongue and salivary glands.
Food moves into the stomach via the esophagus. Thus movement is slow and is aided by the muscles that line the gastro intestinal tract. As such, movement of food through the esophagus is called peristalsis.

The issue of food waste needs to be addressed because it is so significant. Massive foodstuff manufacturing has increased to try to keep up with the rise in the global population. Nearly half of the foodstuff produced worldwide is wasted, and a large portion of it occurs at home because individuals have a practice of throwing leftovers away when they could be reusing them.Eating the leftovers is one way to prevent food waste.

Cystic fibrosis is a recessively inherited disorder that results from a mutation in the gene encoding CFTR chloride ion channels located on the surface of many epithelial cells. As shown in the figure, the mutation prevents the normal movement of chloride ions from the cytosol of the cell to the extracellular fluid. As a consequence of the mutation, the mucus layer that is normally present on the surface of the cells becomes exceptionally dehydrated and viscous.
An answer to which of the following questions would provide the most information about the association between the CFTR mutation and the viscous mucus?
O Is the mucus also secreted from the cells through the CFTR proteins?
O What is the change in nucleotide sequence that results in the CFTR mutation?
O How does the disrupted chloride movement affect the movement of sodium ions and
water by the cell?

Answer: First off, this makes us dependent on something that is finite. Non-renewable resources such as fossil fuels will eventually run out due to the fact that the dead organisms that have been undergoing the process of becoming carbon (more or less) for millions of years won't have anything to replenish them. Along with that, environmental problems occur like we all are seeing in the United Kingdom and even in the US.

Which parts of a plant are responsible for reproduction? Describe the role that each of them will play.
Describe what occurs during the process of seed development.
Based on your knowledge of flowers, why do you think most flowers are bright in color?
The parts of a plant that are responsible for reproduction are the flowers, they are present only in the most evolved group of plants called angiosperms. Flowers can be hermaphroditic or monoecious when they have both female (carpels) and male (stamens) structures.
Describe what happens during the seed development process.Germination is a succession of stages that resume the development of the embryo and the beginning of the formation of a new seedling. We can summarize germination as the process of transforming the seed into a new plant. The seed consists of the embryo, endosperm and integument.
Based on your knowledge of flowers, why do you think most flowers are brightly colored?Are mainly related to pollination by animals. This is due to the fact that the flower acts as a form of attraction for pollinators, therefore, mechanisms are needed to guarantee the visitation of these animals.
With this information, we can conclude that flowers inherit their appearance through genes. Pigments are born in these plants, producing a range of colors across the spectrum. The same chemical, carotenoid, that produces the pigment in tomatoes and carrots also produces the yellow, red, orange colors in certain flowers.

Why oxygen to form oxyhemoglobin but not haemoglobin oxide
Oxygen will form oxyhemoglobin and not hemoglobin oxide because it is referred to as a`protein which binds to oxygen atoms in the blood.
What is Hemoglobin?This refers to a protein in the body which carries oxygen molecules to various parts of the body. This is as a result of the compound which is referred to as heme which is responsible for the high affinity for oxygen. It ensures oxygen is distributed to other parts of the body.
On the other hand, formation of oxides means that a chemical reaction occurred with oxygen. There is however no chemical reaction formed as a result of this affinity which is why there is no formation of hemoglobin oxide in this specific type of scenario in the body system.
This therefore is the reason why oxygen forms oxyhemoglobin but not hemoglobin oxide and makes it the most appropriate choice.

How can scientist explain our ability to feel empathy? Can evolution explain the types of group’s primates will organize themselves in? What is different about Homo sapiens from other non-human primates? Does this explanation make sense to you? Why or why not?
Empathy is a feeling that, in short, represents the ability to put yourself in the other person's shoes. This encompasses thoughts, actions or feelings regarding whatever subject is being addressed.
Can evolution explain the types of primates in the group into which they will organize themselves?As they age, the saddles become larger and eventually cover most of their backs. The most common social group pattern among semi-terrestrial primates is the multimale-multifemale group. With this pattern, there are no stable heterosexual bonds--both males and females have a number of different mates.
How is Homo sapiens different from other non-human primates?Upright posture, arms shorter than legs, extraordinary brains. While the natural "lottery" acted on these and other characteristics, primitive man climbed a new rung of the evolutionary scale. "In evolutionary terms, it is important to think that it is not adaptation that arises to respond to environmental needs; a variation happens and the environment ends up favoring it"
With this information, we can conclude that We are all descendants of Homo sapiens that originated in Africa. Thanks to genetics, we know that all Homo sapiens are descended from an African woman who lived about 200,000 years ago.
