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.

is Turner syndrome an autosomal recessive gene?
Answer:
No, it's dominant.
Explanation:
It is an autosomal dominant genetic disorder and is not a chromosomal disorder.
Answer:
NO!
Explanation:
It is an autosomal dominant genetic disorder and is not a chromosomal disorder. Turner syndrome (TS), sometimes referred to as congenital ovarian hypoplasia syndrome, is a genetic disorder. It is the most common sex chromosomal abnormality affecting girls and women. More specifically, it's a problem with one of the two X chromosomes -- the thread-like structures inside cells that are made of DNA.

What are the phenotypes of an organism?
A. the organism's genes
B. the organism's physical traits
Answer:
A.
Explanation:
The term "phenotype" refers to the observable physical properties of an organism; these include the organism's appearance, development, and behavior. An organism's phenotype is determined by its genotype, which is the set of genes the organism carries, as well as by environmental influences upon these genes.
Answer:
A. the organism's genes
Explanation:
The phenotypes of an organism are the genes carried by the organism.

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.

Because of their capacity for rapid growth and reproduction, or because their new environments are devoid of any native predators or pests, invasive species frequently thrive in their new ecosystems. Thus, option B is correct.
What is a characteristic of invasive species?An invasive species doesn't develop slowly; on the contrary, they accelerate their growth because they are superior to all other species and have taken over the area completely.
Because of this, invading species may pose a threat to native species and interfere with crucial ecosystem processes.
A species must be easily adaptable for it to be invasive. It needs to multiply swiftly. It must result in harm to local property, the local economy, or the local fauna and flora. Accidental introduction of invasive species into a new area is common.
They are so successful because they can adapt and aren't intrusive. Because they have no competition, they are thriving while not being threatened.
Therefore, They take resources from native species.

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. ...

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:
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
