What do excitatory neurotransmitters cause?
Neurotransmitters might be either excitatory or inhibitory.
As the term suggests, excitatory neurotransmitters are in charge of exciting the postsynaptic cell.
Once the neurotransmitter is released from the presynaptic membrane, it travels through the synaptic space until it reaches the postsynaptic membrane.
When the molecule meets its receptor, it triggers a series of events that excite the receiving neuron increasing the action potential effects and allowing messages to be passed from one cell to the other.

Freckles are caused by a dominant allele (F).
Marcus and Olivia have recessive homozygotes for the characteristic, ff, if neither of them has freckles.
Olivia's genotype is thus ff.
Marcus has a ff genotype.
Given that they are both recessive homozygotes for the ff gene, there is little chance that their offspring will have freckles.
2.
The straight hairline allele, W is recessive to the widow peak allele, W.
Marcus and Olivia share the hairline trait heterozygosity Ww.
The likelihood of a widow having children is highest when:
Ww = Ww, Ww, Ww, and ww
Widow's peak probability (WW or Ww) equals 3/4
The likelihood that a youngster will have a straight hairline is 1/4.
The likelihood that the offspring will be homozygous
3.
The attached-lobule trait, e, is recessive to the free-lobule trait, E.
The trait, EE, is homozygous dominant in both parents.
One to zero is the ratio of free to connected lobes.
The offspring will be homozygous dominant free lobules, EE, in all cases.
4.
The ability to taste bitter flavors is dominant (T).
Marcus is a recessive homozygote for the trait "tt" since he cannot sense bitterness.
Olivia possesses a "Tt" heterozygote for the trait.
Tt tt equals Tt, Tt, tt, and tt.
There is a 50% chance that each of their kids will try the PTC paper.
Violet's genotype is tt since she cannot taste PTC paper.
5.
T, tongue rolling is a dominant characteristic.
Marcus and Olivia both have tt genotypes since neither of them can roll their tongues.
tt = tt = tt = tt
Therefore;
Their offspring won't be able to roll their tongues.
No hybrids will be born to them.
The entire family shares the genetic tt.
6.
A dimple is a dominant trait (D)
The four youngsters all have dimples.
Therefore,
It's possible that both of their parents carry the dominant allele for the characteristic "DD" or
One of them is heterozygous, or "Dd," and the other is homozygous.

What are some land adaptations of vertebrates?
The vertebrates that first invaded the land possessed a series of pre-adaptations, such as air-breathing and limb-based locomotion, that allowed them to move about effectively on land; however, other behaviors such as reproduction and swallowing likely tied these vertebrates to the water
When moving to land, animals faced several changes to adapt to the new environment, like lung and limbs development, tegumentary cover, and internal fertilization.
Which are the adaptations of vertebrates to land habits?
Any change to a new environment needs adaptations.
Aquatic animals had to face many changes in their morphology and physiology when changing to terrestrial habits. Some of them are,
Lung developmentThe most significant change is probably lung development, needed to produce gas interchange between tissues and the air.
Once on the ground, animals need to interchange oxygen and carbon dioxide with air. They managed to do so through the respiration process in which the circulatory and respiratory systems work together.
Tegumentary coverAnimals needed to develop a new thicker and harder tegumentary cover.
It needed to be more resistant, especially to avoid or reduce dehydration.
Also, the tegument provides protection when facing new environmental pressures -predation among them-.
Limbs developmentAnother significant change was limb development, which was obviously needed to move on the ground.
Locomotion on the ground required a new pattern of bone arrangement and many muscle changes.
The muscular system suffered many modifications because animals needed to move facing gravity pressure.
Internal fertilizationAnimals needed to face another change related to their reproductive system.
They could no longer make use of external fertilization, as they used to do in aquatic environments.
They developed reproductive organs needed to insert sperm cells into the female body and fertilize the egg cells inside the females.

A normal breath takes in about 1.0 L of air. If air has an average molar mass of 28.8 g per 1 mol and has a density of 0.97 g/mL, how many molecules of air do you take in with each breath
Taking into account the definition of density and Avogadro's Number, you take 2.0286×10²⁵ molecules of air.
What is densityDensity is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.
In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.
Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:
[tex]density=\frac{mass}{volume}[/tex]
What is Avogadro's NumberAvogadro's Number or Avogadro's Constant is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.
Amount of molecules of airIn this case, you know that:
Density= 0.97 [tex]\frac{g}{mL}[/tex]Volume= 1 L= 1000 mLReplacing in the definition of density:
[tex]0.97 \frac{g}{mL}=\frac{mass}{1000 mL}[/tex]
Solving:
mass= 0.97 [tex]\frac{g}{mL}[/tex] ×1000 mL
mass= 970 g
Air has an average molar mass of 28.8 g per 1 mol. Then 970 grams are contained in 33.68 moles.
Now, considering the definition of Avogadro's number you can apply the following rule of three: If 1 mole of air contains 6.023×10²³ molecules, 33.68 moles contains how many molecules?
amount of molecules = (33.68 moles× 6.023×10²³ molecules)÷ 1 mole
amount of molecules= 2.0286×10²⁵ molecules
Finally, you take 2.0286×10²⁵ molecules of air.
