Could a desert form at 45°N latitude
dedylja [7]
Deserts tend to form around 30 latitude because that region is the subtropics where they experience high air pressure so clouds won't form and there would be very little or no precipitation and because it is far inland so far away from bodies of water so to answer your question no probability not

Punnet squares help Fill in the Punnett square for breeding a female chocolate lab (bbEE) with a male black lab (BbEE). bE bE bE
IrinaVladis [17]

Answer:

See the answer below

Explanation:

First, we need to identify the gametes that would be produced by each gene.

bbEE will produce bE, bE, bE, bE.

BbEE will produce BE, BE, bE, bE.

<em>These gametes will then be aligned at the horizontal and vertical side of the Punnet's square to give the genotype of the offspring as shown in the attached image.</em>

On the pH scale, acids fall between ____ and bases fall between
skelet666 [1.2K]

Answer:

The correct answer is - O and 6.9; 7.1 and 14

Explanation:

A measuring scale that tells about the acidity or basicity or alkaline nature of a particular object or solution is possible with the help of a pH scale that measures how acidic or basic a solution or object is.

It ranges between 0 to 14. pH less than 7 or ranging from 0.0 to 6.9 is acidic and more than 7 or from 7.1 to 14.0 is basic or alkaline in nature. A measure of the relative amount of H+ ion and OH- ions in water is pH.

Give two reasonsthat may account for the continuous firing of a<br> PostsynapticNeuron.
lyudmila [28]

Answer:

1.Continuous diffusion of negatively charged ions into the postsynaptic neurons , <u>which  leads to continuous reversal of charges (hyperpolarization) and therefore continuous firing of action potential</u>

2. Inhibition of hydrolytic enzymes e.g (acetycholinesterase)   that  metabolize activities of  cholinergic   neurotransmitters  e,g acetycholine at post synaptic cleft. leading to firing of action potential.

Explanation:

Neuron whose dendrites  transmits action potential to the  neuromuscular junction is called presynaptic neuron. While  neuron that  transmit action potential away from the neuronal synaptic junction, or from the neuromuscular  junction to the cell body of adjacent neuron or to effectors (gland and muscles) are called  post synaptic  neuron.

The more  negatively charged ions that diffused into the post synsptic neuron, the more depolarization, and the greater the frequency of action potential produced

The inhibition of  activities of hydrolytic enzyme which metabolize cholinergic neurotransmitter leads to  continuous   excitatory activities  of cholinergic neurotransmitters   on  the receptors at the postsynaptic neuron, and the more  action potential
