Can you explain the relationship between EPSP, IPSP and action potentials?
Answer:
EPSP and IPSP trigger action potential
Explanation:
“EPSP” means “excitatory postsynaptic potential” which occurs when +ively charged ions move towards the postsynaptic cell thereby depolarizing of postsynaptic membrane potential. IPSPs are inhibitory postsynaptic potential. Whenever the EPSPs or IPSPs changes, the , neurotransmitters bind to receptors thereby opening or closing ion channels in the postsynaptic cell and hence triggering the Action potentials which is basically nerve impulses or spikes.

4. What are carbon dioxide levels now? How often in the past 650,000 years have they been that high?
short answer please:)
Answer:
Explanation:
Scientists at the Mauna Loa observatory in Hawaii say that CO2 levels in the atmosphere now stand at 387 parts per million (ppm), up almost 40% since the industrial revolution and the highest for at least the last 650,000 years.
A material was cooled from 100ºC to 40ºC. What is the temperature change?The specific heat of water is 4.18J/goC. I need the full explanation would mean a lot to me.
Answer:
-60°C
Explanation:
According to this question, a material was cooled from 100ºC to 40ºC.
The temperature change, which is symbolized by ∆T = final temperature - initial temperature
That is, ∆T = T2 - T1
In this question, T2 = 40°C, T1 = 100°C
Hence, ∆T = 40°C - 100°C
∆T = -60°C

A stable ecosystem is characterized by having A)predators that outnumber their preyB)a continual input of energyC)limited autotrophic nutritionD)no competition between species
Answer:
B) a continual input of energy.
Explanation:
An ecosystem can be defined as the natural living habitats of both living and non-living organisms, in which they interact with one another. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.
An ecosystem is generally considered to be stable if it's capable of applying self-regulating mechanisms in order to return to an equilibrium state, after an experiencing an outside disturbance or perturbation. Thus, a stable ecosystem maintains a natural balance of nutrients and energy.
In an ecosystem, producers are the living organisms that are capable of manufacturing their own food and as such can provide energy or food for the other living organisms (consumers) in a food chain. Thus, producers are mainly known as the foundation of a food chain and are at the top.
Generally, a producer gets energy from the sun and converts it into food. The cells found in producers are capable of converting the energy received directly from the sun into food through a process generally referred to as photosynthesis, converting carbon dioxide from the air, water from the soil, minerals and energy from the sun into organic nutrients.
Hence, a stable ecosystem is characterized by having a continual input of energy.

Answer:
it is B
Explanation:
Two indicators that will help you in determining which way to mount bite-wing radiographs are (1) the curve of Spee curves _______________ toward the distal, and (2) mandibular molars have __________ distinct roots.
Answer:
The correct answer is - upward, two.
Explanation:
The bitewing radiograph (BW) is a radiography image that is used to see the crowns of the maxillary and mandibular teeth, the interproximal surfaces of the teeth, and identifying interproximal caries.
The curve of the spee is also can be seen and mount with this image the curve of the spee is start at the tip of the lower canine, rn with the buccal cusp tips of the premolars and molars and continuing to the anterior end of the ramus. it is 2-D and upward from distal. It also shows that mandibular molar teeth have two distinct roots.

Imagine that a friend read this same article and summarized it by saying, "Because there are more
plants now, the amount of carbon dioxide in the atmosphere is decreasing." What is incorrect about
your friend's assessment?
Answer:
The amount of carbon dioxide in the atmosphere is increasing, not decreasing. However, it is not increasing as fast as scientists predicted it would, which they attribute to the amount of carbon dioxide absorbed by plants.

Which one is more biologically disruptive a point mutation or a frameshift mutation
Answer:
Frameshift
Explanation:
A point mutation can be insignificant due to the genetic code, many amino acids come from similar codons (where one base can be incorrect and it results in the same amino acid). If it does change the amino acid, having only one different amino acid in a whole polypeptide chain usually does not cause a major problem.
However, a change in the reading frame can be a major issue because it changes every codon form what it should be. A frame shift mutation can even prevent the translation of a protein entirely if it effects the start or stop codon.
Terribly articulated, but the answer is 100% frameshift
