How has the settlement of humans in agricultural societies impacted the environment
Answer:
The settlement of humans in the field and agricultural societies brings many problems to the environment that must be adressed in order to prevent ecological disasters and the bad use of our natural resources.
Explanation:
Our race, society and companies must be properly educated on how to settle, manage and deal with our resources, especially those within the agricultural society. A good education and culture can create conscience about taking advantage of our resources and reducing the impact of bad use of resources or explotation of resources.

A scientific question can be answered by proposing a hypothesis based on which experiments can be performed. The experiments will provide observations based on which the scientific questions can be answered.
In the given question, since the selected options can be answered by following the scientific method therefore these selected questions can be considered scientific questions.
lipid
protein
amino acid
nucleic acid
carbohydrate
All of these organic molecules are _________ - based molecules.
A) carbon
B) hydrogen
C) oxygen
D) water
Answer:
The correct answer will be option-A.
Explanation:
Organic molecules are the molecules which are composed of the carbon atoms attached with other elements like oxygen and hydrogen.
It is the property of carbon atoms that leads to the formation of a large number of compounds like the ability to form bonds with other carbon also known as "Catenation" and the capability to attach four other atoms due to four free valent called "tetra valency".
Since the biomolecules are made up of long chains of monomers sue to carbon atom therefore, option A is the correct answer.
Which of the following elements is the most reactive?
Chlorine
Bromine
Fluorine
Helium
Answer:
Fluorine
Explanation:
Answer:
The answer to this question would be: Fluorine
Explanation:
Fluorine is one of the halogen gas that is known as highly reactive. It should be the most reactive element in the periodic table. All halogen gas is reactive because they need 1 more electron to complete their set of valence electron. The nonreactive element would be the noble gas which has a full set valence of the electron.

What would happen to the size of the herbivore population if the producer population decreased?
Answer:
If the producer population decreased, the size of the hervibores population will diminish.
Explanation:
Producer population refers to autotrophic organisms (plants for example). These organisms are the nutrition source for primary consumers (like hervibores). So if the nutrition source decreased, the population size of hervibores will decreased too.

Manuel's teacher asked the class to make a wet mount slide of their cheek cells. Manuel made his slide and placed it on the microscope stage. Then he got ready to view his cheek cells by following these procedures. 1. Looking through the eyepiece, Manuel adjusted the diaphragm so field of vision was lit. 2. Manuel looked at the stage from the side and lowered the body tube so the high power objective was almost touching the slide. 3. Looking into the eyepiece, he very slowly turned the coarse adjustment to bring the cells into focus. What suggestion would you make to Manuel to CORRECTLY use the microscope to view his cheek cells? A) close the diaphragm B) start with the low power objective C) do not look at the stage when lowering the body tube D) start with the body tube raised and lower it while looking through the eye piece
Answer:
B
Explanation:
Manuel start with the lower power objective for correctly use the microscope. Thus option B is correct.
What are the different parts of microscope ?Microscopes is the instrument used to visualize very minute objects like cells, and microorganisms and it gives a highly magnified and contrasting image.
It is made up of magnifying lenses, each having its own magnification powers. This will magnify the specimen according to its focal strength and it also depend on types of lenses.
The different structural parts of the microscope i.e. head, base, and arm; Head is known as the body which carry optical parts in the upper part of the microscope.
The base of microscope acts as support and carries microscopic illuminators whereas the part connecting to the base and to the head and the eyepiece tube to the base of the microscope which gives support to the head of the microscope.
Thus option B is correct.

why would a fish that lives in the bathypelagic zone lack a swim bladder,and what adaptations would help it maintain neutral buoyancy?
A fish in the bathypelagic zone may lack a swim bladder due to the high pressure that makes it impractical; instead, they have adaptations like less bone mass, high lipid levels, specialized tissues, and gelatinous tissue to maintain neutral buoyancy.
A fish that lives in the bathypelagic zone might lack a swim bladder because the high pressure at deep sea levels would make it difficult to maintain a gas-filled organ for buoyancy control. Instead, these fish have other adaptations that help maintain neutral buoyancy. This includes adaptations such as minimal bone mass, increased levels of lipids that are less dense than water, and specialized tissues that can absorb gases from the water directly, minimizing the need for a swim bladder. They may also have a more watery, gelatinous tissue that provides buoyancy without the necessity of a gas-filled organ.
While swim bladders are used by many bony fishes to control their buoyancy, allowing them to maintain their position in the water column without expending energy, not all fish possess swim bladders. In the deep sea, conditions such as extreme pressure make swim bladders less functional or too costly in terms of biological energy to maintain. Therefore, fish in these environments have evolved alternative strategies to regulate their buoyancy and adapt to their hypertonic surroundings.
These adaptations not only help the fish conserve energy but also avoid predation and increase their efficiency in capturing prey, which is scarce in such deep zones of the ocean.
Process in which cells develop special structures and functions
When 2 or more atoms bond together, they form ____________.
A. Elements
B. Covalents
C. Ions
D. Molecules
Final answer:
When 2 or more atoms bond together, they form (option D) molecules, which are two or more atoms held together by chemical bonds. These can be atoms of the same element or different elements that come together to form compounds like water or methane.
Explanation:
Molecules are made up of two or more atoms held together by chemical bonds. For instance, when two hydrogen atoms and one oxygen atom share electrons via covalent bonds, it forms a water molecule, H₂O.
Molecules can consist of atoms of the same element, like O₂ or H₂, which are forms of oxygen and hydrogen, respectively. Or, they can consist of atoms from different elements bonding together to form compounds, such as water (H₂O) or methane (CH₄).

The nurse admits an infant who is nutritionally deprived. the infant is weak and seems somewhat uninterested in food. in developing the infant's plan of care, how often will the nurse most likely plan to feed this infant?
The baby refusing his food is not unusual. Just continue on giving the baby milk formula since it is important in his feeding. The baby can take maximum of 32 ounces a day. Then offer single-ingredient foods with no sugar or salt and wait three to five days between each food. In this way if the baby has a reaction you will know why. After some days, you can give the baby combination of Important nutrients, cereals, vegetables and fruits if he reached 8 months. If babies still reject food, do not force it. Try again in a week. If the problem continues, tell the doctor to make sure that there is no problem.

Human chromosomes are made up of dna and proteins called ________, which help organize the dna and give structure to the chromosomes.
Human chromosomes are made up of dna and proteins called histones.
What are histone?Histones are a class of alkaline (basic pH) proteins that connect with DNA in the nucleus and aid in condensing it into chromatin. They are positively charged, which enables them to bind to DNA.
They are located in eukaryotic cells' nuclei. The nucleosome, which is made up of DNA and histones, is a pack known as chromatin, and a chromosome is made up of two chromatin.
Histones primary functions are compact DNA strands and impact chromatin regulation. Chromatin is a combination of DNA and protein which makes up the contents of a cell nucleus.
Therefore, Human chromosomes are made up of dna and proteins called histones.
