Assume all of the presynaptic synapses identified produce epsps. If two of these synapses fired simultaneously, which synaptic combination brings the initial segment closest to threshold based on spatial summation?.
The synapses that are nearer to the axon hillock would bring the initial segment closest to the threshold based on spatial summation.
What is neuron synapsis?In neurosciences, the term synapsis makes reference to the connection between two nerve cells (neurons).
Synapsis is produced by the connection between axons and dendrites among different neurons.
Spatial summation refers to the start (trigger) of the action potential in neurons via two or more presynaptic cells.

Energy in an ecosystem flows directly from _______. a. producers to tertiary consumers b. producers to secondary consumers c. tertiary consumers to secondary consumers d. secondary consumers to tertiary consumers please select the best answer from the choices provided a b c d
Answer:
A.
Explanation:
Primary producers use energy from the sun to produce their own food in the form of glucose, and then primary producers are eaten by primary consumers who are in turn eaten by secondary consumers, and so on, so that energy flows from one trophic level, or level of the food chain, to the next.
Energy in an ecosystem flows directly from producers to tertiary consumers. So, the correct option is A.
What do you mean by Ecosystem?An Ecosystem may be defined as an area where organisms of different species are present together in a given time and interact with one another in order to survive.
In an ecosystem, producers produce the energy in the presence of sunlight through the process of photosynthesis. And then passes its energy to primary consumers (herbivores), then primary consumer passes their energy to secondary consumers (carnivores), then secondary consumers pass their energy to tertiary consumers. According to Lindeman, only 10% of energy get transferred to each trophic level.
Therefore, Energy in an ecosystem flows directly from producers to tertiary consumers.

List all the gametes that are possible with each of the following genotypes.
a. Aabb
d. AABb
b. AaBB
e. AAbb
C. AaBb
f. aabb
All the possible gametes for Aabb would be Ab and ab; that of AABb would be Ab and AB; that of AaBB would be AB and aB; that of AAbb would be Ab; that of AaBb would be AB, Ab, aB, and ab; and that of aabb would be ab respectively.
Gametes formationThe formation of gametes for a dihybrid involves the crossing of the two traits involved.
Thus: Aabb is equivalent to crossing Aa and bb
Aa x bb
Ab Ab ab ab
Hence, all the gametes would be Ab or ab.
For AABb: AA x Bb = AB Ab AB Ab
The gametes are either AB or Ab
For AaBB: the gametes are either AB or aB
For AAbb, only Ab gametes are produced
For AaBb: the gametes would be AB Ab aB and ab
For aabb: only ab gametes are produced.

A cross between a yellow snake and a blue snake produces offspring that are all green. What type of inheritance is this?
Answer:
co dominance
Explanation:
codominance is a type of inheritance in which both allels are dominat over each other and the two allels are expressed to an equal degree in an offspring,that is why the cross between yellow and blue snake give another green colour offsprings in stead of giving all blue or all yellow offsprings depending on which allel is dominant.
as example we can take human blood group AB which is inherited from blood group A and B and both allel A and B are dominant over each other.

Often, ____________ or basidiomycetes are the fungi involved, and they form several layers of hyphae, one of which envelops the photosynthetic ____________ .
Most of the time in lichen, ascomycetes or basidiomycetes form the fungal part with several hyphae layers enveloping the photosynthetic algal part.
LichensLichens are composite organisms. They are formed from a symbiotic relationship between fungi and algae. The fungi provide shelter and some vital minerals for the algae while the algae provide food via photosynthesis.
Oftentimes, the fungi components are usually ascomycetes or basidiomycetes. They form a network of hyphae around the photosynthetic algae as a form of protection.

Are heated air and wind shear the cause for severe storms? Explain.
Answer:
Yes, they are very much the main cause of severe storms because the heat molecules get into the atmosphere and clouds, causing chemical reactions and damage. At some point in time, the energy built up, as well as the damage done, must undo itself. This is done through a storm. It is the environment's way of cleaning itself.
As a part from this video below states, wind shear is a leading cause in severe storms.
