Which of the following best explains the reason humans migrate from one location to another? (3 points) I think is A
Resource availability
Improved worldwide health care
Improved sanitary conditions
Lack of technological advances
Answer
Improved worldwide health care
Explanation:
You may have resources to uild you many things or do you many things but when you have health care advantages there would be less people sick nowadays. When you have improved world wide health care you have a more chance of living and have a better opportunity to live a longer life and a low percent of you getting sick and dying. When you just have resources, those resources can reserve you clothes, houses, and other materil things but if your health is very bad it dosent matter if you have those resources because you will have a highr percenatge of getting sick and dying.

dna samples from four different organisms were analyzed using a procedure that separates the dna in each sample by size.What procedure was used to obtain these results?
Answer:
The correct answer is - Gel electrophoresis.
Explanation:
Gel electrophoresis is a lab technique used to separate distinct samples of mixed DNA, RNA, or proteins on the basis of their size. In gel electrophoresis, the molecules to be move from one another by an electrical field through a gel with small pores in it. DNA molecules are negatively charged so they move towards positive charge wells in the electric field and get separated.

Create a city of your choice and assign each of the major organelles from our guided notes to a part of the city.
Draw your city on a piece of paper. Use your creativity and imagination!
Write your analogy to show the similarity between the cell part and the part of the city. Be sure to explain the reasoning behind your analogies. The cell analogies and functions should be written.
Example- The nucleus controls the cell just like how town hall coordinates a city.
You will create this on a sheet of paper or on a digital document that works best for you.
Make sure to include each organelle, what it does, and what it could represent within a city! Be creative!
Answer:
A cell is like a city
Example
The nucleus controls the cell just like how the town hall coordinates a city.
1) The vacuole is a supply centre just as they are the large groceries in the city.
2) The mitochondrion is the supplier of ATP to the cell, as well as the electric power plant in the city.
3) The Golgi Apparatus is responsible for packaging and modifying proteins as well as distributing chemical messages in the cells just as the post office works in the city.
4) The ribosomes they produce from raw material RNA finished products named proteins as the factories do.
5) The cell wall protects the cell as the fortifications do in the city.
6) The cell Membrane allows the communication of the cell with the environment through the transport of information just like the city limits, through tollbooth or carrier proteins.
7) Lysosomes process cellular material down to simpler and smaller molecules like the city's recycling plant does.
8) The endoplasmic reticulum allows the movement of proteins in the cell as do the roads in the city.
Explanation:
Unfortunately, I do not know the organelles that you present in your guide, however, I give you an example with the most important.
The vacuole is responsible for storing food, liquids and wastes and/or enzymesThe mitochondrion is the energy-producing organelle synthesizing ATPThe Golgi apparatus handles synthesized proteins to transport them to other places in cellsRibosomes are responsible for reading DNA and producing proteins.The cell wall gives structure and protects the cell.The cell membrane regulates transport into and out of the cell.Lysosomes are responsible for degrading intracellular material. The endoplasmic reticulum is a network of membranes that allows the movement of proteins and other molecules.If any of you have ever taken the "Biomes Escape Room - The Hunt For Shangri-La" please give me the answer key, I don't quite understand it.

Nutrients in absorbed food contain energy, which is measured in ________.
Answer:
I will explain in the explanation
Explanation:
Carbohydrates, proteins, and fats supply 90% of the dry weight of the diet and 100% of its energy. All three provide energy (measured in calories), but the amount of energy in 1 gram (1/28 ounce) differs: 4 calories in a gram of carbohydrate or protein.

due to my reasons we all know we are in the end time the trumpet can just come from else where and true believer will accomplish the kingdom
Answer:
These species are not able to survive and hence become extinct. Human activities such as fragmentation cause the genetic diversity to become lowered for organisms of a species. As a result, a disaster such as a disease results in killing all the organisms of a species present in a community.

Explanation:
Organisms which "hold an ecosystem together" because they have a significant role to play are called
A.endemic species
B.native species
C.niche species
D.keystone species
Answer:
native species
Explanation:
MY answer is B,
because that is what I think.
Food webs are unable to cross from one environment into another (e.g., from land to water).
TRUE
FALSE
Answer: false, for example, if a frog eats flies, and the flies are land animals, if they go extinct the frogs could die off, meaning any fish or water dwellers that eat the frogs can starve and cause a large chain reaction.
Hope this helps ^^
Why is overfishing dangerous?
Answer:
If you're overfishing at the top of the food chain, and acidifying the ocean at the bottom, you're creating a squeeze that could conceivably collapse the whole system that's my answer
Answer: If over-fishing occurs it can create a void in the food chain. For example, if someone over fishes salmon, then the bass that eat said salmon can starve, and die off, then others predators that eat bass can starve and die off as well. It's a chain reaction like with the dinosaurs. How the ashes from the meteor killed the plants and then the herbivores died, then the Carnivores and omnivores starved and died as well. The chain reaction starts with one thing, over-fishing to fish, is like the meteor to the dinosaurs.

(NO FILES PLEASE) All organisms' cells contain DNA. Every organism's DNA is made of nucleotides. Although, the four species on this phylogenic tree are different, which components of their DNA are the same?
Question 4 options:
(A) sugar deoxyribose and the base thymine.
(B) sugar deoxyribose and the base uracil.
(C) sugar ribose and the base thymine
(D) sugar ribose and the base uracil.
The components of DNA that will be similar in the given organisms will be deoxyribose sugar and base thymine. So the correct answer is option A.
This is because humans, chimpanzees, and gorillas have DNA as their genetic material. And DNA is composed of a phosphate group, a deoxyribose sugar, and the four bases adenine, guanine, cytosine, and thymine.The sugar ribose is not found in the DNA and is known to occur in the RNA. Also base uracil is not found in the DNA.
So ribose sugar and uracil base can never be found in the genome of the organisms which posses DNA as their genetic material.

What are molecules and how are they used in running? Evidence
What is homeostasis and how does homeostasis work to maintain internal stability? Evidence
Answer:
Osmosis helps cells maintain homeostasis because a cell needs to maintain a specific water balance so that chemical reactions can take place. Osmosis can also be used to balance out the concentration of other molecules (such as sugar or salt) present on either side of a cell membrane.
Explanation:
Homeostasis is the ability of a system to regulate its internal environment through maintaining a stable, relatively constant set of properties such as temperature and PH. Key Terms homeostasis : The ability of a system or living organism to adjust its internal environment to maintain a stable equilibrium, such as the ability of warm-blooded.
