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.

b

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.

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.

sam enjoys looking at the stars through his telescope he learns that start were originally clouds made of dust and gasses which statement best describes how these clouse eventually become stars
A. The clouds eventually collapse the force of gravity
B. The clouds increase in temperature until they eventually form a solid
C. The clouds contain particles that are magnetically attracted to each other
D. The clouds begin to cool and fort from masses of ice that eventually fuse together
Answer: A
Explanation:
The statement which best describes how the clouds eventually become stars is that— “The clouds eventually collapse under the force of gravity”. Hence, the correct option is A.
What are stars?Star are huge celestial bodies that are formed by the vast clouds that exist in interstellar space. These clouds are mainly composed of hydrogen and helium gas as well as small amounts of heavier elements such as carbon, nitrogen, and oxygen.
Overtime, the clouds begin to collapse under their own gravity and as they do, they become denser and more compact. As the cloud collapses, it begins to spin and then flattens into a disc-like shape. This disc becomes the birthplace of new stars.
The process of star formation is not simple and straight forward. Hence, the first step of formation of stars is the cloud collapses under its own force of gravity. Therefore, option A correct.

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 sort of receptor do skeletal muscle cells use to receive signals from somatic lower motor neurons?
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.

Describe how the movement of water landforms form
Answer:
The moving of water causes erosion, deposition and much more!
Explanation:
Water moving across the earth in streams and rivers pushes along soil and breaks down pieces of rock in a process called erosion. The moving water carries away rock and soil from some areas and deposits them in other areas, creating new landforms or changing the course of a stream or river.

with white flowers. Weeks later, she discovers that all of the offspring have
dark blue flowers. Ileana determines the

Answer:

Explanation: it is dominant because the plants didnt show and white
A plant breeder is trying to increase the medicinal quality of belladonna (Atropa belladonna), which is derived from atropine, an alkaloid in the roots. Her previous research indicates that about 55% of atropine variation is due either to environmental factors (e.g., soil conditions or rainfall), or to genetic dominance and genetic interactions. If the average plant has 10 units of atropine and our breeder selects for plants with an average of 50 units of atropine, what will be the average amount of atropine in the new population
Answer:
The average amount of atropine in the new population will be 32 units of atropine.
Explanation:
To answer this question, we need to remember how can we calculate the selection differential and the heritability in the narrow sense.
• We can get the selection differential, SD, by getting the difference between the mean value of the population´s units of atropine, PoUA, and the mean value of the parents´ units of atropine, PaUA. So, in this example the selection differential is:
SD = PoUA - PaUA
SD = 10 - 50
SD = - 40
• The heritability in the narrow sense, h², for units of atropine in the population is
h² = units of atropine of the offspring average/selection differential
But we already know the value of h² = 55% = 0.55. And we want to know the units of atropine of the offspring. So we just need to clear the following equation.
OUA = PoUA + h² ( PaUA - PoUA)
where,
• offspring average units of atropine = OUA
• population average units of atropine = PoUA = 10 units
• parents average units of atropine = PaUA = 50 units
• Selection diferential = SD = -40 units
• narrow sense heritability = h² = 0.55
OUA = PoUA + h² ( PaUA - PoUA)
OUA = PoUA + h² (SD)
OUA = 10 + 0.55 x ( 50 - 10)
OUA = 10 + 22
OUA = 32 units.

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.

What observation supports the claim that earth rotates
Answer:
The most direct observational evidence for Earth's orbital motion is the apparent shift of nearby stars after six months, as the Earth moves from one side of its orbit to the other. Because of the large distance to even the nearest start, this parallax shift is too small to been seen without a telescope.

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.
