Name & describe the six essential activities of the digestive tract.
Answer:
Ingestion: Consuming something orally, whether it be food, drink, medicine, or other substance; the first step of digestion. bolus: a round mass of something, especially of chewed food in the mouth or alimentary canal.
Propulsion: Propulsion means to push forward or drive an object forward. A propulsion system is a machine that produces thrust to push an object forward. On airplanes, thrust is usually generated through some application of Newton's third law of action and reaction.
Mechanical Digestion: Mechanical digestion is a purely physical process that does not change the chemical nature of the food. Instead, it makes the food smaller to increase both surface area and mobility. It includes mastication, or chewing, as well as tongue movements that help break food into smaller bits and mix food with saliva.
Chemical Digestion: Chemical digestion involves the secretions of enzymes throughout your digestive tract. These enzymes break the chemical bonds that hold food particles together. This allows food to be broken down into small, digestible parts.
Absorption: Absorption is a condition in which something takes in another substance. The process of absorption means that a substance captures and transforms energy. The absorbent distributes the material it captures throughout whole and adsorbent only distributes it through the surface.
Defecation: Defecation is the term given for the act of expelling feces from the digestive tract via the anus.

Answer:
At B part.
Explanation:
At B part the nightfall will happen first because the B part is in the shade and will not present in front of the sun. When the earth rotates its own axis, the shaded part which is B comes in front of sun which means day time is started while on the other hand, the A part is in the shade and will experience nightfall so we can say that the nightfall occurs at B part of the earth.

Explanation:
the reason this mouse shows natural selection is that the black mouses are more adapted to their environment compared to the tan mouses as the tan mouses are more easily spotted and eaten by the bird. since the black mouse is more adapted to it's environment it is more likely to live on and pass it's trait of the black fur color to it's offspring while the tan mouses are not.
Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish than they are to insects? (1 point) The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans, O All these organisms require oxygen to survive. O The earliest fish fossils are found in the lowest strata of sedimentary rocks, followed by insects, and then humans. O Fossils of ancient fish and human ancestors have been discovered in the same sedimentary rock layers.
Answer:
The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans,
Explanation:
It tells you that fish and humans have very similar embryo development (fetus development) while humans and insects develop very differently. Therefore, that supports the argument that humans are more like fish than insects.
Answer:
(Q1) Most people develop wisdom teeth by early adulthood. Wisdom teeth can cause pain or crowd out their other teeth, so many people have these teeth removed. Wisdom teeth in modern humans do not perform a crucial life function.
(Answer)They are vestigial structures that once performed an important function for human ancestors.
(Q2) Which statement is true?
(Answer) Imprints of leaves or footprints in sedimentary rock are fossils.
(Q3) Which statement about these fossils is supported by the evidence in the diagram?
(Answer) Homo erectus is the most recent ancestor to modern humans.
(Q4) Which of the following pieces of evidence would best support the argument that humans are more evolutionarily related to fish than they are to insects?
(Answer) The early stages of embryo development in fish and humans look strikingly similar while insects develop very differently compared to both fish and humans.
(Q5) Human embryos have tails, which become tail bones before birth. Tails also appear in fish, reptiles, amphibians, birds, and mammals. Humans also have hair and produce milk to nourish the young, which is unique to mammals. What does this indicate?
(Answer) a close evolutionary connection between humans and many other mammals

What characteristics of the blood cell helps it to pass freely through blood capillaries
Answer:
The cell is flexible and assumes a bell shape as it passes through extremely small blood vessels. It is covered with a membrane composed of lipids and proteins, lacks a nucleus, and contains hemoglobin—a red iron-rich protein that binds oxygen.
Answer:
The cell is flexible and takes the form of a bell through extremely small blood vessels. It is clothed in a fluid and protein-membrane, lacks a nucleus, and has hemoglobin—a rich red iron protein that binds oxygen.
Explanation:
The hemoglobin in red blood cells contains four iron-binding heme groups.
Heme groups of hemoglobin are binding on oxygen. Each molecule of hemoglobin can bind up to four molecules of oxygen.
Hemoglobin has a cooperative binding affinity to oxygen. The saturation of the molecule increases by oxygen. The connection of the initial molecule of oxygen affects the form of the other binding sites. For additional oxygen molecules, the binding becomes more favorable.
The four iron-binding hemo-groups are located in each hemoglobin molecule. Hemoglobin is known as oxygen-bound hemoglobin.
The reversible carbon dioxide is transformed into the carbonic acid reaction by the enzyme carbenoid anhydrase by the Red blood cells altering the blood PH.
Instead of being converted to carbonic acid, pH is controlled by carbon dioxide bindings to hemoglobin.
CO2: The enzyme found in RBCs catalyzing the reaction between carbonic anhydrase and carbonate dioxide and water.
Co-operative binding: When a first molecule is binding to a binding location, the same molecule is favored for the remainder of the binding locations by means of increased binding affinity.

Explain in at least five sentences what you've learned about how
global warming and climate change are impacting our Earth in different regions of the world.
Explanation: I'd first address the issue as a whole and explain the meaning and the general impacts of climate change, then use a variety of different places. For example, global warming causes the ice caps to melt in Antarctica. Then, explain how this has an impact on the environment meaning that polar bears could be in life-threatening situations and possibly even become extinct in the future which has a further impact on other animals in that food chain and ecosystem. This is just one example. You could also explain the unbearable heat in countries nearer the equator, which prevent crops from growing; the sea levels rising; or extreme weather events like huge flooding or heatwaves. It depends what you have learnt about in class, but I'm assuming it would be about this sort of thing.
Answer:
Higher death rates. ...
Dirtier air. ...
Higher wildlife extinction rates. ...
More acidic oceans. ...
Higher sea levels.

In the lab activity, you will use a chemical called a pH indicator that changes color as the pH of a
solution changes. If you added a pH indicator to two different solutions and they both turned the
same color, what would this tell you about the pH of each solution?
ph indicator is used to find the acidic or basic nature of a mixture.
there is a range of colours from red to blue
red colour indicates that solution is acidic and blue colour indicates that solution is basic
if two solutions have same colour that means they also have same ph value

what is the part of endoplasmic reticulum without proteins attached?
Answer:
Regions of ER that lack bound ribosomes are called smooth endoplasmic reticulum, or smooth ER.
Answer:
The ER regions lacking bonded ribosomes are referred to as the smooth or smooth endoplasmic reticulum.
Explanation:
The Endoplasmic reticulum is a membrane network within the cell that transmits proteins and other molecules. Proteins called ribosomes are assembled at organelles. The ribosomes that are assembled to the endoplasmic reticulum give it a rough look when proteins are intended for cell membrane or export from the cells. Smooth endoplasmic ribosomes are absent and help to synthesize and concentrate various cell-required substances.
Either a smooth or rough endoplasmic reticulum is capable of producing protein in general for the rest of the cell to function. The raw endoplasmic reticulum contains ribosomes, small, red organelles that make these proteins. Sometimes the proteins remain inside the endoplasmic reticulum when made incorrectly.
It is retained and the endoplasmic reticulum is engulfed because it appears to be stuck in a way that does not lead the protein where it is supposed to go. There is also the smooth endoplasmic reticulum on which these ribosomes are not contained. This smooth endoplasmic reticulum produces other materials that the cell needs. The endoplasmic reticulum is an organelle that actually produces proteins and substances that are necessary for the rest of the cell.
