Why is it so important that we think about waste and what happens to it? *
Yes Its Important
yes it's good important to know about placed because if you think about waste then what saving the earth and remember that and plastic or wood will keep us and USA backlash tired and save future of tomorrow a mother nature and so is a very good thing to think about ways are the best thing about you will reset and two more things and have people and mark my words this happy a lot thank you have a nice day
Answer:
Mainly because it can destroy our lives. Waste is usually thrown into waste pits or places specifically for waste but what happens when there is no more place to put it? It can cause pollution and harm to wild life so if we pay more attention to it and try to stop how much waste is thrown out then maybe the earth will be able to live longer.

Answer:
Due to the movement of surounding water ijnto the cell.
Explanation:
A red blood cell placed in distilled water will swell and burst due to the movement of - water molecules moving by osmosis into the cell.
Osmosis is the movement of water that diffuses from a higher water concentration area to a lower water concentration area.
The distilled water outside the red blood cell, since it is 100% water and no salt, is hypotonic to the red blood cell.The red blood cell will gain water, swell ad then burst.Thus, a red blood cell placed in distilled water will swell and burst due to the movement of - water molecules moving by osmosis into the cell.

If there are 10 chromosomes in a particular cell at the start of prophase how many will be present in the same cell at the end of anaphase. Before cytokinesis has begun? Hint: first of all, state the number of chromosomes. Then explain why you think so.
Answer:
20 chromosomes
Explanation:
Mitosis is a kind of cell division that results in daughter cells with same number of chromosomes as the parent cell. It involves stages including Prophase, Metaphase, Anaphase and Telophase. In prophase, the Chromatin condenses into Chromosomes.
In Anaphase stage, the 10 chromosomes as mentioned in the question divides into opposite poles of the cell. One individual chromosome contains two sister chromatids, which actually separates in the Anaphase stage. Hence, at the end of the Anaphase stage, there will be 10 chromatids each at opposite poles of the cell. Each chromatid at this stage is considered a chromosome.
Hence, a cell with 10 chromosomes will contain 20 chromosomes (10+10 chromatids on each pole) in the Anaphase stage just before the cell divides into two in a process called CYTOKINESIS.

During daylight savings, Christie's neighborhood soccer games get cut short because the sky becomes dark much earlier than during the summer. Her father talked to the electric company about installing large lights above the field so Christie and other kids in the community could continue their soccer games after dark. The electric company informed Christie's father that although the light poles could be installed, there are too many short trees and trees with low branches in the park to connect electrical lines. Without electricity delivered to the light poles, they would not work. Christie and her father talked about this information with neighborhood residents and together they came up with several ways to solve the problem.
Considering the concerns of everyone involved, which idea would be the BEST solution to the problem?
A)
Instead of electrical light poles, install solar-powered light poles.
B)
Parents can leave their cars running with headlights on facing the park.
Build several large fire pits around the field and light them each night.
D)
Cut down the larger trees, install the electrical lines, and replant the area

A student made a model of an onion skin cell she viewed using a microscope. The scale is 1:500.The students cell model has a length of 15cm. How many centimeters is the real cells length?
Answer:
Length of the real cells = 7500 cm
Explanation:
A scale model is a physical representation of an object that has the same aspects as that of the object.
A scale model can be used in fields like engineering, film making, salesmanship, etc
Length of the student's cell model = 15 cm
The scale is [tex]1:500[/tex]
So,
Length of the student's cell model / Length of the real cells = [tex]1:500[/tex]
15 / Length of the real cells = [tex]1:500[/tex]
Length of the real cells = 15 × 500 = 7500 cm
Answer:
7500 cm

The system in the body which carries information from the glands and organs to brain is endocrine system.
What is endocrine system?
All mammals, birds, fish, and many other forms of living things have endocrine systems, commonly known as hormone systems. They are composed of:
Throughout the body, there are glands; hormones that are produced by the glands and released into the bloodstream or the fluid around cells; and receptors in various organs and tissues that detect the hormones and react to them.
All bodily components are affected by hormones, but only target cells with the right receptors can react. In both humans and other vertebrates, more than 50 hormones have been discovered.
Therefore, The system in the body which carries information from the glands and organs to brain is endocrine system.

What are some examples of comparative embryology in evolution?
Answer:
Similarities in structure among distantly related species are analogous if they evolved independently in similar environments. They provide good evidence for natural selection. Examples of evidence from embryology which supports common ancestry include the tail and gill slits present in all early vertebrate embryos.
how does the virus use a host cell to make copies of itself
Answer:
I wasn't quite sure what virus you were referring to in your question, but here's a general answer: Viruses use their host cells' machinery to replicate themselves.
If they are a specific type of virus known as a retrovirus, they have the ability to use the host cells' enzymes to change the RNA contained within the virus into DNA (via some type of replication I suppose).
In other cases, if they contain DNA instead of RNA (that is, the virus), they can use the host cell's machinery to create RNA via enzymes involved in transcription and/or they can incorporate that DNA into the host cell's DNA. This is part of a type of viral replication cycle known as the lysogenic cycle.
In another type of viral replication cycle known as the lytic cycle, the virus simply has itself and its genome duplicated until the host cell bursts, releasing the viral material. Here, again, the virus uses the host cell's machinery to replicate itself.
Mandy and Pat are discussing a movie that showed someone being injured by radio waves. Mandy says that's not likely because radio waves are low frequency and low energy, and Pat says that it is likely because otherwise they would not put it in a movie. What is the best way to help them decide if the information is true?
Answer:
I think the answer is C.
Explanation:
The best way to help them to decide about the information of the scenario is that they can use reliable web sites or books to get more information. The correct option is C.
What are reliable information?Reliable information or data is accurate or trustworthy: Broker-dealers must use their discretion when determining whether issuer information is reliable.
Trustworthy information/data/evidence currently, investors do not always have timely access to reliable information.
Reliable data must come from trustworthy sources. A reliable source will provide a "thorough, well-reasoned theory, argument, etc. based on strong evidence," according to UGA Libraries.
Scholarly, peer-reviewed articles and books are examples of highly credible sources.
Recognizing the type (genre) of knowledge you are going to encounter allows you to predict its form, function, and context, making what you find more understandable and assisting you in determining the information's relevance and validity.
