The central nervous system includes all of the following except: brain spinal cord nerves that reach the tissues in limbs cerebellum
Answer:
My answer is the CNS consist of the brain and the spinal cord nerves but not cerebellum.
The nerves that reach the tissues in limbs is not the part of the central nervous system.
• The central nervous system or the CNS mainly is formed of the spinal cord and the brain. However, it generally is considered to exhibit seven fundamental parts, that is, the spinal cord, the pons, the medulla, the midbrain, the cerebellum, the cerebral hemispheres, and the diencephalon.
• The parts of the nervous system apart from the brain and the spinal cord is known as the peripheral nervous system.
• It comprises the spinal nerves, the cranial nerves and their roots and branches, the neuromuscular junctions, and the peripheral nerves.
• The bundles of axons or the nerve fibers transmit information to and from the central nervous system in the peripheral nervous system.
Thus, the nerves that reach the tissues in the limbs is the part of peripheral nervous system not central nervous system.

a hypothesis that has support to back it up and is yet to be disproved
Answer:
a theory
Explanation:
A hypothesis that has support to back it up and that is yet to be disproved can be referred to as a theory.
Ordinarily, a hypothesis is a tentative statement that has not been proven in any way. Once a hypothesis has supports to back it up and there are no counter-evidence to disprove it, it becomes a theory.
In other words, a theory is a proven hypothesis and it remains so until there are overwhelming evidence to counter the supporting evidence.
Using the formula in your notes, calculate the growth rate for a population of 1,200 with a carrying capacity (K) of 2,000 and a maximum per capita growth rate (rmax) of 0.3.
Answer:
The correct answer is : 144.
Explanation:
Given:
K or carrying capacity = 2000
N or population size = 1200
rmax or maximum per capita growth rate = 0.3
formula:
growth rate = [tex](rmax) (N) \frac{K-N}{K}[/tex]
Solution:
by the formula ,
growth rate =
[tex](0.3) (1200) \frac{2000-1200}{2000}[/tex]
= [tex]360 [\frac{800}{2000}][/tex]
= 360 × 0.4
= 144
Thus, the correct answer is : 144.
Why do field researchers and laboratory researchers use tools that are similar and tools that are different
Answer:
Please see below
Explanation:
These two types of research, that is, in the laboratory and in the field, are very different from each other for a number of reasons. For one, the study is conducted on a much larger scale when it is done in the field as compared to when it is confined in the lab.
Tools such as PCR (polymerase chain reaction) would be common between the two since there is no substitute for it. However, other tools used that have various other purposes will be different between the lab and the field. For instance, a quadrant will be used to count plants in a field, but none is needed in the lab due to a smaller number of plants being studied.

True or False: In an experiment to avoid errors you should only change one variable, all other factors should remain the same.
Answer:
True
Explanation:
In an experiment, if you change more than one variable at a time, you will not know what is causing the potentially different outcome. If you only change one variable and leave all other factors constant, you will know exactly what is causing the data.

How does the distance from this eye chart affect the number of letters visible on a line? What factor of the experiment is the eye chart? Control Group, Control Variable, Independent variable, or Dependent variable
Answer:
This question is asking to identify the variable in the experimental statement.
The eye chart is the CONTROL VARIABLE
Explanation:
An experiment consists of several variables to look out for in order to achieve any significant result. These variables are independent variables, dependent variables and control variables. Although independent and dependent variables are the major experimental variables, but control variables are also important.
A control variable is the variable that remains constant or unchanged throughout the experiment. Any change to the control variable will affect the dependent and independent variables. In this question, the eye chart is the CONTROL VARIABLE because it remains constant or unchanged. The same eye chart is used for the experiment.
N.B: The distance to the eye chart is the independent variable while the number of letters visible on the line is the dependent variable. Hence, changing the eye chart (control variable) will affect the distance and the number of letters visible.

Why don't the spontaneous deleterious mutations that occur in an individual
e.coli cause downward drops in fitness in this population? see section 23.6 ( page 475) ?
Answer:
Please see below
Explanation:
The reason behind this is the phenomenon of natural selection. The deleterious mutations do not provide a survival advantage so they are selected against, which results in these type of mutations to not be passed on - rather, they eventually get eliminated from the population.

El parental portador aporta un alelo normal y un alelo alterado. Tiene el 50% de probabilidad de transmitir la enfermedad a la progenie.
Parental) AA x Aa
Gametas) A A A a
Cuadro de Punnet) A A
A AA AA
a Aa Aa
F1) 2/4 = 1/2 = 50% de la progenie seran individuos sanos AA
2/4 = 1/2 = 50% de la progenie seran individuos portadores Aa
Como uno de los progenitores es portador, cada individuo tiene un 50% de posibilidades heredar el gen alterado.
