Answer:b
Explanation:
Polar molecules have ends or poles that are partially charged. The opposite ends of a polar molecule will
have____.
A. the same type of charges
B. opposite charges
Answer:
B. opposite charges
Explanation:
Polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end.
Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms.
The use of energy and matter by living organisms
_________
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.

Answer:
She takes medication that increases the level of dopamine in the brain.
Hope it helps.
Sue has Parkinson's disease. She takes medication that increases the level of dopamine in her brain.
What is Parkinson's disease?
It is a neurodegenerative disorder characterized by a loss of dopamine-producing cells in the brain, particularly in an area called the substantia nigra.
Dopamine is a neurotransmitter that plays a crucial role in coordinating movement and regulating various brain functions.
In Parkinson's disease, dopamine deficiency leads to impaired communication between brain cells, resulting in the motor symptoms associated with the condition, such as tremors, stiffness, and difficulty with movement and coordination.
To address this dopamine deficiency, medications known as dopamine agonists or levodopa are commonly prescribed.
These medications work by increasing the levels of dopamine in the brain, compensating for the deficit caused by the disease.
Thus, Sue takes medications that increase the level of Dopamine.

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.

which one of the following processes does not occur to excess neurotransmitters in the synapse
This question is incomplete because the options are not given; here is the complete question:
Which one of the following processes does not occur to excess neurotransmitters in the synapse?
A. Break down or digested into inactive fragments.
B. Collection by scavenger vesicles left over from the neurotransmitter release.
C. Drifting away from the synapse via diffusion.
D. Reuptake within the pre-synaptic neuron.
The answer to this question is B. Collection by scavenger vesicles left over from the neurotransmitter release.
Explanation:
The word synapse refers to the neurological structure that allows the transmission of signals or information between neurons. This process occurs through neurotransmitters, which are the molecules or substances with the messages.
Moreover, in this process, there can be in some cases excess. In this situation, the body reacts to this excess by degrading or breaking down the extra neurotransmitters, eliminating it through diffusion, or even reabsorbing it (reuptake). In this context, all are processes that occur due to excess neurotransmitters except collection by scavenger vesicles because in most cases neurotransmitters are simply absorbed or eliminated but there are not specialized scavenger vesicles that collect them.

How many neutrons are The process of fusion and fission are completely different. Fusion combines two light atoms together and fission splits the nucleus of a large unstable atom. What is the MAJOR similarity between the two? in the isotope Carbon-14?
Answer:
Examples of fission and fusion
For example, the so-called hydrogen bomb (or H bomb) is actually a deuterium–tritium bomb (a D–T bomb), which uses a nuclear fission reaction to create the very high temperatures needed to initiate fusion of solid lithium deuteride (6LiD), which releases neutrons that then react with 6Li, producing tritium.

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 )

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.
