The cell membrane is ----------in nature
a. Highly permeable b. normally permeable c. not permeable d. partially permeable
Answer:
d. partially permeable
Explanation:
The cell membrane is the cellular organelle that covers and bounds all cells. It forms a boundary around a cell, protecting all other organelles. The cell membrane, according to the FLUID MOSAIC MODEL, contains phospholipid bilayer, proteins etc.
The phospholipid (lipid) content of the cell membrane confers its ability to be SELECTIVELY OR PARTIALLY PERMEABLE upon it. It is said to be partially permeable because it allows the passage of some molecules/substances and blocks the passage of others.

The diagram below shows three families. Which set of parents has the highest fitness?
A
the parents of the single child
B
the parents of two children
C
the parents of the big family
Answer:
C. the parents of the big family
Explanation:
In biology, an organism that produces as much offspring is said to have a higher fitness compared to its counterpart. It is said to be biologically fit than the rest.
Therefore, in the same vein, the parents that has the biggest family is the most biologically fit of the three families.

what is the function of a membrane protein
Answer:
Membrane proteins can allow hydrophilic molecules to pass through the cell membrane.
Explanation:
Answer:
Explanation:
Membrane proteins are common proteins that are part of, or interact with, biological membranes. Membrane proteins fall into several broad categories depending on their location. Integral membrane proteins are a permanent part of a cell membrane and can either penetrate the membrane (transmembrane) or associate with one or the other side of a membrane (integral monotopic). Peripheral membrane proteins are transiently associated with the cell membrane.

A ______ is a type of turbine used to capture the energy of moving air. A. geotherm B. windmill C. solar panel D. dam
Answer:
b windmill
Explanation:
A windmill is a type of turbine used to capture the energy of moving air.
Windmills have been used for centuries to power grain mills, water pumps, and other mechanical devices. In modern times, wind turbines are often used to generate electricity on a large scale.
Wind turbines typically consist of a rotor with two or three blades that spin around a horizontal or vertical axis. As the wind blows, it pushes the blades, causing them to rotate and give energy. The rotating blades turn a shaft, which is connected to a generator that produces electricity.
Wind turbines can range in size from small turbines used to power individual homes or businesses to large utility-scale turbines used to generate energy for the grid.

Populations that experience exponential growth have unlimited sources. A population can not continue to grow
exponentially indefinitely. Eventually, the population of a species will reach their limit. What curve will occur when a
population has reached this limit and what are some possible reasons for this curve shape?
PLSSS HELPPP
Answer:
Carrying capacity
Explanation:
Carrying capacity is the limit to which a population can grow with the resources (food, water, oxygen, habitat space, etc.) are available to support them. Once they reach the maximum population that the environment can support, they reach their carrying capacity.
Sally, 9-year-old girl, just did an awesome backflip on her trampoline. Instead of landing in a similarly awesome manner, she miscalculated and landed on her neck. Sally stood up with pain in her neck and does not appear to be able to extend her left arm very well. An x-ray shows a fracture of her C6 vertebrae that is compressing down on her C7 vertebrae impacting the spinal nerve located between C6 and C7 vertebrae. Which spinal nerve did Sally likely injure
Answer:
The C7 spinal nerve
Explanation:
The C7 spinal nerve exits on each side through the intervertebral foramen between the C6 and C7 vertebrae. The C7 spinal nerve has both a sensory root which is composed of sensory fibers and a motor root. This nerve is required to control motor functions including shoulder movement (i.e., adduction, abduction and rotation). The C7 dermatome is a region of skin that receives sensory inputs from the C7 spinal nerve.

Using the law of superposition and the principle of cross-cutting relationships, which of the layers of rock in this image is younger than layer C and closest in age to layer C?
A: Layer A
B: Layer E
C: Layer D
D: Layer B
Answer:
D. Layer B
Explanation:
The correct answer is Layer B.
The law of superposition actually states that the sedimentary rock unit is at the bottom while the the youngest rock is at the top. The principle of cross-cutting relationships states in layers of rocks, a fault or intrusion that cuts through rock layers is younger than the rocks that it cuts through.
Layer B was actually formed after Layer C. This makes Layer B younger than Layer C and closest in age to Layer C. The intrusion, Layer D is the youngest of all.

a. Nicotinic
b.Muscarinic
c.Adrenergic
d.Mechanoreceptive calcium channels
Answer:
C
Explanation:
Skeletal muscle cells use Adrenergic receptor to receive signals from somatic lower motor neurons ; ( C ) Adrenergic
Skeletal muscles are organs of the muscular system found in vertebrates. they are attached to the skeletal bones through tendons. they all posses the longest of all muscles cells as well.
Skeletal muscles receive signals from somatic lower motor neurons through the Adrenergic receptor found in all cell and tissues .
Hence we can conclude that skeletal muscle cells use Adrenergic receptor to receive signals from somatic lower motor neurons.

What are the advantages and disadvantages of the serial dilution-agar plate procedure?
Answer:
Advantages
- Serial dilution is used in microbiology to estimate the concentration or number of cells/organisms in a sample to obtain an incubated plate with an easily countable number of colonies.
- In biochemistry, serial dilution is used to obtain the desired concentration of reagents and chemicals from a higher concentration.
- In pharmaceutical laboratories, serial dilution is performed to receive the necessary concentration of chemicals and compounds as this method is more effective than individual dilutions.
- In homeopathy, homeopathic dilutions are used where a substance is diluted in distilled water or alcohol. It is believed than dilution increases the potency of the diluted substance by activating its vital energy.
Disadvantages
- An error might occur during the propagation of the sample, and the transfer inaccuracies lead to less accurate and less precise transfer. This results in the highest dilution to have the most inaccuracies and the least accuracy.
- Because serial dilution is performed in a stepwise manner, it requires a more extended period of time which limits the efficiency of the method.
- Serial dilution only allows the reduction of bacteria/cells but not the separation of bacteria/cells like in other techniques like flow cytometry.
- This technique also requires highly trained microbiologists and experts in aseptic techniques.

If a cytosine replaces a guanine in a strand of DNA, this is known as what type of mutation?
Substitution mutation
Deletion mutation
Insertion mutation
Corruption mutation
Answer:
substitution
Explanation:
c replaces g. does not cause a frameshift mutation so it is not insertion or deletion, and i have no clue what corruption is when there is the word "replace" it is probably substitution.
Answer:
Substitution mutation
Explanation:
Mutation refers to a change in the genetic sequence of an organism. Mutation can be of different types depending on how it occurs. A type of mutation called SUBSTITUTION MUTATION involves the replacement of a nucleotide base by another in a gene.
For example, as stated in this question, when a cytosine (C) replaces a guanine (G) in a strand of DNA, it is called SUBSTITUTION MUTATION because guanine base replaces cytosine base in the sequence.
