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.

Biological knowledge is important in all of the following except
Answer:
both a body of knowledge and an intellectual activity encompassing observation, description experimentation, and explanation of natural phenomenon.
Explanation:
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.
hope it helps

what are mammals? what are the examples of mammals?
Answer:
Mammals are a group of vertebrate animals constituting the class Mammalia and characterized by the presence of mammary glands which in females produce milk for feeding (nursing) their young, a neocortex (a region of the brain), fur or hair, and three middle ear bones. These characteristics distinguish them from reptiles and birds, from which they diverged in the Carboniferous, over 300 million years ago.

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

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
