Which of the following is an acid?
NaOH
NaCl
HCI
CH4
Answer:
HCl
Explanation:
Some easy ways to identify if a compound is an acid is to locate an H+ proton, while basic compounds will have an OH- ion.
Examine all the choices:
A) NaOH
Already, we see that OH is here, so it's a base, not an acid. Eliminate.
B) NaCl
This doesn't have an H+ or an OH-, so it's not an acid. It's actually a salt. Eliminate.
C) HCl
This does have an H+, so it's an acid.
D) [tex]CH_4[/tex]
Although this does have an H, it's a hydrocarbon - an organic compound. So, it's not an acid.
The answer is thus C.

Fill in the blank
Answer:
Embryology is the study of a embryo which is a fertilized egg attached to the wall of the mothers uterus by umbilical cord.
Embryology refers to the study of an embryo, which is a fertilized egg attached to the wall of the mother's uterus.
What is embryology?Embryology can be defined as a branch of biology that involves the study of the early development of a fetus and an embryo from a single-celled zygote, especially in female organisms (mothers).
In this context, we can infer and logically conclude that embryology involves the study of an embryo, which is a fertilized egg that is typically attached to the wall of the mother's uterus.

According to the article, what are the problems with monoculture farming? Your answer should be written in sentences and not constructed as a list.
Answer:
In addition to overproduction, industrial monoculture predisposes farms to pest problems. To keep up with intensified production, farmers increased pesticide and fertilizer usage, crop density, and the number of crop cycles per season, but decreased crop diversity
Explanation:
Monocultures lack other plant and animal species that limit the transmission of disease and manage pests through predation, which increases the danger of disease and pest outbreaks.
What is monoculture farming?One variety of crop is grown at a time on a particular field in a practice known as monoculture farming. A poly culture system, in contrast, presupposes that two or more crops are sown in a field at once.
Because monoculture farming has the potential to disrupt the natural soil balance, it is not sustainable.
The soil moisture is unstable in a typical monoculture situation. Due to the increased need for water to irrigate crops, water sources including rivers and reservoirs are being unevenly drained.
Therefore, monoculturing is not suitable.

unique physical features of pigeon
Answer:
There are many unique physical features that pigeons have.
Explanation:
Pigeons, according to studies, are surprisingly complex creatures. They have passed the "mirror test"(self recognition), can recognize others, and can recognize every letter of the human alphabet.
There are also incredible physical features.
Plumage is one of these. Their plumage varies, and is unique to the type of pigeon they are. Not only this, but they have the ability to walk, while most other birds hop about.
Something absolutely extraordinary about them is that they have a gland in their throat. That gland actually secretes milk for their offspring, so they have adequate nutrition to grow and develop.
Hope this helps.

Dorsiflexion is the act of bringing the toes closer to the shin, it is also referred to as the backward bending of an individual's foot or hand. when someone is walking on the heels of their ankle, their ankle can be described to be in dorsiflexion. therefore option d answers the question.
How is it possible that all animal life depends on the chloroplast for energy
chloroplast contains chlorphyll . Chlorophyll is used in photosynthesis to produce glucose . (photosynthesis is a process where green plants manufacture simple sugar (glucose) from carbondioxide and water by using sunlight ) 6co2+6h2o=c6h12o6+6o2
if theres no chloroplast no glucose will be produced so animals will have no energy. chloroplast must be present in order of photosynthesis to take place and produce glucose , when plants produce glucose animals get the energy needed by feeding on plants (in simple words animals eat the sugar that plants have produced )

_________
Answer:
it involves chemical cycling from chemical energy from the sun to heat lost from the ecosystem :D
Explanation:
hope this helps, its different options on canvas (plz give brainliest
The use of energy and matter by living organisms involves chemical cycling from light energy from the sun and returning of chemicals to the cycle.
Photosynthesis is the process by which plants and algae use light energy from the sun, water (H2O), and carbon dioxide (CO2) in order to produce oxygen (O2) and energy in the form of simple carbohydrates (sugar).The overall chemical reactions in the photosynthetic process can be written as 6CO2 + 6H2O → C6H12O6 (glucose) + 6O2The biogeochemical cycles refer to the pathways by which essential compounds of living things are circulated.For example, the carbon cycle involves the exchange of carbon between biotic (organisms) and abiotic (environment) factors.During photosynthesis, plants absorb CO2 from the air to produce carbohydrates such as glucose, thereby decreasing the level of CO2 in the atmosphere.Plants in turn serve as food for herbivores.Finally, when herbivores dead, carbon-based compounds are broken down into simpler carbon compounds by decomposers (i.e. bacteria and fungi).In conclusion, the use of energy and matter by living organisms involves chemical cycling from light energy from the sun for the production of chemical energy in food to the decomposition and the returning of chemicals to the cycle.

When adding more sucrose to a 0.7 M sucrose solution, why does it not dissolve as readily as it did at a lower molarity?
a) the ions in the solution interact with the sugar and that interferes with its solubility
b) the solubility of the solute depends on wether the solute has hydroxyl functional groups or not
c) the solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules
d) hydrogen bonds in the water molecules change the electrical charge of the sugar molecule, which prevents it from dissolving further in the water
Answer:
c) the solute molecules adhere to the polar regions of the water molecules so there is no room for more sucrose molecules
Explanation:
A solution contains a solvent (water in this case) and a solute (sucrose in this case). A solution can either be saturated or unsaturated depending on whether it can still dissolve a solute or not.
According to this question, the 0.7 M sucrose solution does not dissolve the sucrose (solute) any longer. This implies that the sucrose solution is getting SATURATED. The saturation of the sucrose solution occurs because the amount of solutes is equating the amount of solvent in the solution.
The solubility of a solution depends upon polarity. The solute molecules (sucrose) adhere to the polar regions of the water molecules (solvent). When this occurs to the point where no other sucrose molecule can adhere, the solution becomes SATURATED so there is no room for more sucrose molecules.
