Answers
Answer: hi im brain bot
im not sure i know this one im stumped
Explanation:
The event occurs as nerve impulse reaches the synaptic knob, neurotransmitter molecules diffuse across the synaptic cleft. These molecules bind to receptors in the postsynaptic cell and voltage change occurs in the postsynaptic cell. A nerve impulse begins in the postsynaptic cell. The correct option is C.
What is synaptic transmission?The metabolic pathway by which a neuron interacts with a target cell across a synapse is known as synaptic transmission.
Chemical synaptic transmission is characterized by the release of a neurotransmitter from the presynaptic neuron and the binding of the neurotransmitter to specific post-synaptic receptors.
Synaptic transmission is the process by which a nerve impulse (action potential) travels from the presynaptic neuron to the post-synaptic neuron across the synaptic gap. An action potential is an electrical impulse that travels down the axon of a neuron.
As the nerve impulse arrives at the synaptic knob, neurotransmitter molecules diffuse across the synaptic cleft. These molecules bind to receptors in the postsynaptic cell, causing voltage changes in the cell. and finally nerve impulse begins in the postsynaptic cell.
Thus, the correct option is C.

Answer:
I don't have the information from the text book but. People might more and more be using clean energy instead of fossil fuel is because fossil fuel is limited. It's a non-renewable, it takes millions of years to form. Also because global warming is making a big impact on our planet, using clean energy instead of fossil fuel can reduce slow green house emission.

since ph can affect the activity of the antibiotics why would the Kirby bauer test require that the agar have a ph of 7.4
Answers
We have that for the Question "since ph can affect the activity of the antibiotics why would the Kirby bauer test require that the agar have a ph of 7.4" it can be said that
Why the Kirby bauer test require that the agar have a ph of 7.4 is because while agents may be in excessive activity, given a scenario that the pH is to exceed 7.4 the results might inverse.
From the question we are told
since ph can affect the activity of the antibiotics why would the Kirby bauer test require that the agar have a ph of 7.4
Generally
Agar has a ph value that should exist between 7.2 and 7.4 within a room temperature,given it solidifies and this should be when initially prepared
Therefore
Why the Kirby bauer test require that the agar have a ph of 7.4 is because
while agents may be in excessive activity, given a scenario that the pH is to exceed 7.4 the results might inverse.

What is cell cycle?The cell cycle, or cell-division cycle, is the series of events that take place in a cell that cause it to divide into two daughter cells.
Moreover, a cell cycle is a series of events that takes place in a cell as it grows and divides. A cell spends most of its time in what is called interphase, and during this time it grows, replicates its chromosomes, and prepares for cell division. The cell then leaves interphase, undergoes mitosis, and completes its division.
The cell cycle consists of a series of steps during which the chromosomes and other cell material double to make two copies. The cell then divides into two daughter cells, each receiving one copy of the doubled material.

The primary purpose of the ______ circuit is for the blood to release carbon dioxide and pick up oxygen.
Answers
Answer:
Explanation:
The primary purpose of the systemic circuit is for blood to release carbon dioxide and pick up oxygen
The primary purpose of the pulmonary circuit is for the blood to release carbon dioxide and pick up oxygen.
What is pulmonary system?It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs.
Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.
The respiratory system makes it possible for the body to take in oxygen and expel carbon dioxide.
The nose and mouth are the beginning of the respiratory system, which continues through the airways and lungs.
The pulmonary circulation serves a variety of crucial purposes. Its main job is to exchange gases across the alveolar membrane.
This ultimately results in oxygenated blood being delivered to the rest of the body and carbon dioxide being removed from the bloodstream.
Thus, the pulmonary circuit's main function is to allow the blood to absorb oxygen and release carbon dioxide.

Energy pyhamids, otherwise known as trophic level diagrams, are used to represent the flow of
energy through an ecosystem. An organisms trophic level indicates the organism's position in
the sequence of energy transfers. The bottom, or base, of an energy pyramid is a position
always held by the producers and represents (by far) the largest percentage of biomass for
the food web. The need for such a large biomass of producers is to support the energy
needs for all the organisms at higher trophic levels. Draw and label an energy pyramid for the
following 1 hectare of farmland:
• 30,000,000 MJ of Sunlight (solar energy) reaches ground level during a 150-day growing
season
• 52,164 MJ of energy is stored in the soybeans grown on the hectare of land
1,645 MJ of energy is stored in edible beef by cattlewho eat the soybeans
Answers
From the total energy that reaches the ground, 1% is used by producers. The energy transference in the trophic web follows the 10% rule, in which each level uses 10% of the energy stored by the anterior level.
---------------------------------------
Only 1% of the total solar energy that reaches the ground is used by producers, who occupy the first trophic level. From this input of solar energy, it begins a unidirectional energy flow through all the organisms in the ecosystem, from autotrophs to heterotrophs, until it is finally dissipated in the environment. At each trophic level, it occurs an energy transfer from one level to the next, with only 10% being usable in each of them. This assessment is called "The 10% rule". This is, as a general rule, only about 10% of the energy stored as biomass at one trophic level, per unit time, ends up as biomass at the next trophic level, in the same unit of time. The progressive reduction of energy determines the number of trophic levels (4 or 5).If 30,000,000 MJ of Sunlight (solar energy) reaches ground, then only 30,000 MJ can be absorbed by primary producers.
5,216.4 MJ from 52,164 MJ of energy stored in the soybeans, are used by cattle.
1,645 MJ of energy is stored in edible beef by cattle who eat the soybeans.
164.5 MJ of this energy is tranferred to the following trophic level.

Meiosis and mitosis are forms of cell divisions that occurs in cells in eukaryotes. This forms of division enables growth and development.
The major way meiosis ii differ from mitosis is that in meiosis II, the daughter cells formed are haploid cells.
Mitosis is also termed as an equational division meaning that the end result yields the same number as the beginning, there is no reduction and resulting cells are still diploid.
In meiosis, there is the reduction in half first in meiosis I then the homologous chromosomes separates at the centromeres in meiosis II resulting in haploid cells.

What is reproduction?
Reproduction is the production of offspring. There are two main forms: sexual and asexual reproduction. In sexual reproduction, an organism combines the genetic information from each of its parents and is genetically unique.
In asexual reproduction, one parent copies itself to form a genetically identical offspring. Sea turtles are an example of an animal that reproduces sexually, a volvox (green algae) is an example of an organism that reproduces asexually, and a brittle star can reproduce in either way.
Reproduction is the process by which new organisms (offsprings) are produced from organisms of the same kind.
