You have lost the paddles for the canoe you rented, and the canoe has drifted to the center of a pond. You need to get it back t

o the shore, but you don't want to get wet by swimming in the pond. Your friend suggests that you drop rocks behind the canoe to create waves that will push the canoe toward the shore. Will this solution work? Why or Why not?

This solution will work, because the amount of rocks and the size of the rocks also depend on how much farther you will move, although once you start to build up a little bit of inertia it will become easier.


Hope this helps!

Answer:

V_{cell = 526.12 μm³

Explanation:

Given that;

A typical human cell is approximately 10.00 μm in diameter    &

enclosed by a membrane that is 8.000 nm thick.

What is the volume of the cell including the membrane?

First, let's determine the radius of the human cell=

= \frac{1}{2}*d

= \frac{1}{2}*10

= 5 μm

Now, the radius of the cell including the membrane

= 5 μm + 8.000 nm

= 5 μm + 0.008 μm

= 5.008  μm

The volume of the cell including the membrane is given by the formula:

V_{cell]= \frac{4}{3} *\pi *(r_{cell})^3 um^3

V_{cell  = \frac{4}{3}*3.142*(5.008)^3um^3

V_{cell = 526.1160731 μm³

V_{cell = 526.12 μm³

Degeneration of the dopamine-releasing neurons of the ________ is the ultimate cause of Parkinson's disease. Degeneration of the
slavikrds [6]

Answer:

a. substantia nigra

b. substantia nigra (it is repeated)

Explanation:

Parkinson's disease is a neurodegenerative disease that is caused by the death of neurons that release the neurotransmitter dopamine in the <u>substantia nigra</u>, or locus niger, -a region of the brain that regulates brain circuits that give the 'orders' to initiate voluntary movements- .

The lack of this neurotransmitter leads to the occurrence of the main symptoms suffered by patients: decreased movements, muscle stiffness, postural instability and tremor. These failures are generated by the abnormal way in which neurons work in the absence of dopamine through a mechanism that is not known in depth.

It is the second most frequent neurodegenerative disease, after Alzheimer's disease, with a prevalence of 2% in people over 65 years. The characteristic symptoms of stiffness, bradykinesia and tremor are associated with losses of neurons in the substantia nigra and dopamine depletion in the striatum. There are large cytoplasmic inclusions, called Lewy bodies, which are the pathological mark of the disease and appear predominantly in neurons that contain melanin of the nigra substance. Genetic studies in a subgroup of families with Parkinson's disease with autosomal dominant inheritance found a locus on chromosome 4q-21 23 and a mutation in the gene that encodes a synaptic protein, α-synuclein.

iris [78.8K]

Answer:

The correct answer is genetic drift.

Explanation:

The phenomenon of changing the frequency of an allele in a specific population with time is known as genetic drift. The mentioned gene variation or the modification in the frequency of the allele is required to take place abruptly so that the phenomenon of genetic drift can take place. The environmental factors do not play an essential role in the phenomenon of genetic drift to take place.  

The process of genetic drift occurs generally due to random sampling of organisms, it illustrates the random change in the number of gene variants within a population. When the existence of the different forms of a gene, that is, alleles, enhances or reduces by chance with time within a population, the phenomenon of genetic drift occurs. Thus, the mentioned case is an illustration of genetic drift.
