why you think the opposable thumb is important to the evolutionary adaptation of humans.
Answers
The opposable thumb in humans helped them in their survival and evolutionary adaptation as it allows them to grasp objects and tools.
What is evolutionary adaptation?Evolutionary adaptation is the adjustment of the species to their new traits and environment to increase their chance of survival through natural selection.
The opposable or the grasping thumb/hand of the primates (humans) is an evolutionary adaptation. It allowed them to grasp the objects and led to the disappearance of the claws resulting in the formation of the fingertip, fingernails, etc.
Therefore, the opposable thumb is important for evolutionary adaptation as it allows the survival of the primates.

Explain/describe how a presynaptic neuron causes an electrical signal on a postsynaptic neuron, when they do not actually touch.
Answers
The action potential causes information to be transmitted from the axon of the first neuron (presynaptic neuron) to the dendrites or cell body of the second neuron (postsynaptic neuron) by secretion of chemicals called neurotransmitters.
How do synaptic transmissions occur?Synapse is the junction between neurons where information gets exchanged.The axon of the presynaptic neuron does not actually touch the dendrites of the postsynaptic neuron and is separated from them by a space called the synaptic cleft. Stimulation of the presynaptic neuron to produce an action potential causes the release of neurotransmitters into the synaptic cleft.Neurotransmitters are stored in small vesicles located in knoblike structures on the axon tips.Most of the released neurotransmitters bind with molecules at the receptors on the dendrites of the postsynaptic neuron.The combination of the neurotransmitter molecules to receptor cell molecules in the postsynaptic cell membrane produces a change of potential in the postsynaptic cell membrane called the postsynaptic potential (PSP).Thus a signal is caused on a postsynaptic neuron.Learn more about neuron here:

The reticular formation controls the activity of the gamma motor system and thus regulates muscle tone.
Gamma motor system (γ motor neuron): It is a type of neuron system that takes part in muscle contraction. Their cell bodies are present in the anterior part of spinal cords which receives the activating input from the reticular formation of the pons in the brainstem. They are not directly involved in lengthening or shortening muscles rather they function in pulling or stretching muscle spindles which then maintain the firing of alpha neurons resulting in muscle contraction.
These gamma neurons are more active and effection when their axons are surrounded by myelin [a lipid-rich material] as compared to non-myelinated axons.

Which was a result of the human genome project
Answers
Answer:
Anatomy
What did the Human Genome Project accomplish?
In essence, it served as a standard for how a human genome appears. One of the first stages in determining if a mutation causes an illness is realizing that there IS a mutation. In order to compare it to "regular" human DNA sequences, we completed the human genome project. Similar to this, a human genome sequence is required in order to compare a human genome or gene to that of a dog or a fruit fly. It essentially changed us from doing genes one at a time to performing them in bulk. You can quickly trace a novel mutation or gene back to the reference genome to determine its location, typical sequence, etc.
Neanderthal genome sequencing is a nice illustration of this. In the absence of a reference genome to match it to, it was just a collection of random sequences. They were able to align and compare the reference human genome to determine precisely how humans vary from Neanderthals. That's a fascinating and significant piece of study that would not have been possible without the creation of a high-quality human reference genome.
which hip bone forms the superioir part of the pelvic girlde that extends upward from the acetabulum
Answers
The ischium bone forms the superior part of the pelvic girdle.
What is the structure of the pelvic girdle?
In the bottom region of the trunk, there is a bony structure known as the pelvic girdle that resembles a ring. It joins the lower limbs to the axial skeleton. There are two types of pelvises: the bigger pelvic and the lesser pelvis.
The pelvis is made up of two paired hipbones that are joined at the pubic symphysis in front and by the sacrum in back. Each hipbone is composed of three bones: the blade-shaped ilium above and to either side, which determines the hips' width; the ischium below, on which the weight is placed when sitting; and the pubis in front. Early in maturity, all three come together at a triangle suture in the acetabulum, the cup-shaped socket that connects to the head of the femur to create the hip joint.

Which type of mutation is seen in a sperm cell but not in a skin cell?
Answers
Answer:
An alteration in DNA that occurs after conception. Somatic mutations can occur in any of the cells of the body except the germ cells (sperm and egg) and therefore are not passed on to children. These alterations can (but do not always) cause cancer or other diseases.
Explanation:
when a skin stem cell harbors a cancer-driving mutation, it becomes more likely to generate two specialized skin cells when it divides. Over time, the mutated skin stem cell fails to renew itself and turns into cells that eventually slough off, allowing the skin to expel mutated cells as needed.
Errors in DNA copying during cell division and development can cause new mutations — called de novo mutations — at any time from the moment of conception. Mutations that occur in the germ line — the cells that develop into sperm or eggs — can be passed on to the next generation and, perhaps, cause disease in children.

Enzymes are the proteinaceous molecules that speed up the biochemical reaction taking place inside living systems.
Apoenzymes are the catalytically inactive form of the enzyme that is present in the cells when the enzyme is not required. It activates upon the binding of a cofactor. Apoenzymes are not capable of catalyzing a reaction. It is considered an incomplete enzyme.
Holoenzymes are the active form of enzymes. When the enzyme binds to the cofactor, it is the catalytically active form known as the holoenzyme. It is considered the complete enzyme.
Apoenzymes form when the cofactor or coenzyme is removed from the active site of the enzyme and only the protein component is left alone, it is catalytically inactive.

When the sarcomere contracts and shortens,D) the A band stays the same.
When a sarcomere contracts, the Z strains flow nearer together and the I band receives smaller. The A band remains equal width and, at full contraction, the skinny filaments overlap. Whilst a sarcomere shortens, some areas shorten while others live the equal length.
At some stage in muscular contraction, the myosin heads pull the actin filaments closer to one another ensuing in a shortened sarcomere. while the I band and H sector will disappear or shorten, the A band length will continue to be unchanged.
A sarcomere is described as a distance between the Z-strains. The Z-strains are pulled closer together for the duration of contraction and move in addition apart in the course of relaxation. The Z-traces are closer for the duration of contraction because actin and myosin interplay generates pass-bridges, which slide the myofilaments over every other.
