which features are found only on thoracic vertebrae?
Answer:
The characteristic feature of thoracic vertebrae is the presence of joints that articulate with ribs. A mid-thoracic vertebra (shown here) has two joint facets on the vertebral body for the heads of adjacent ribs, and a third joint facet on the transverse process for the neck of a rib.

The negative membrane potential in a resting neuron is primarily due to :___________
a. high levels of chloride ions in the cell. diffusion of potassium out of the cell.
b. a higher permeability of the membrane for potassium compared to sodium.
c. both diffusion of potassium out of the cell and a higher permeability of the membrane for potassium compared to sodium are correct.
Answer:
c
Explanation:
When the membrane of the neuron is in a state of rest, the interior of the cell has a more negative charge in relation to the exterior, therefore option "c" is correct.
What is the membrane potential in a resting neuron?It is a phenomenon that occurs when the nerve cell membrane is not altered by action potentials.
Characteristics of a resting neuronThe resting potential is determined by the concentration gradients of the ions, both inside and outside the neuron, and by the permeability of the membrane.When a cell is at rest, the potassium channels are open, the potassium will tend to flow outwards (K ions), they are positive charges, therefore the cell interior will be negative with respect to the cell exterior.Therefore, we can conclude that the resting potential of a membrane occurs when they are not transmitting signals.

Which traits in the investigation showed incomplete dominance?
Answer:
A child born with semi-curly/wavy hair
Explanation:
A child born with semi-curly/wavy hair is individuals exhibiting incomplete dominance because the crossing of parents alleles both straight and curly hairs to produce such offspring. Thus, incomplete dominance occurs to produce an intermediate trait between the two parent traits.

what can the enzyme sucrase break down?
Answer:
Sucrase is an enzyme that breaks sucrose down into glucose and fructose.
Explanation:
The bonds between the glucose and fructose molecules making up the disaccharide sucrose break due to the enzyme sucrase, and water is added as
H
and
OH
to the two molecules. This is called a hydrolysis reaction.
Hydrolysis is a chemical reaction in which water (hydro) breaks (lysis) a chemical bond in a dimer (two molecules bonded) and polymer (many molecules bonded) by adding
H
to one molecule and
OH
to the other molecule.
which sensorimotor substage is focused on reflexes?
Answer:
According to Piaget, cognitive development includes six substages in the sensorimotor stage:
Stage 1 - Reflexes (newborns between birth and one month) For example, infants exercise, improve, and organize the reflexes of sucking, looking, listening, and grasping.

The inflammatory response is a defense mechanism that evolved in higher organisms to protect them from infection and injury. Its purpose is to localize and eliminate the injurious agent and to remove damaged tissue components so that the body can begin to heal.
Explanation:
What problems do animal cells have since they don't have cell walls?
Answer:
These antibiotics bond to protein molecules on the existing wall and prevent the cell from adding any new material as the wall stretches. When the cell wall stretches too far, it becomes weak and eventually bursts, destroying the cell. Since animal cells don't have cell walls, they are not affected by penicillin.
Explanation:
the __________ vertebrae articulate with the corresponding ribs.
Answer:
Each vertebra contains three points of articulation with ribs. The superior demifacet of a thoracic vertebra articulates with the corresponding rib (costovertebral joint). This rib articulates again with the costal facet on the transverse process (costotransverse joint). The inferior demifacet articulates with the rib below.

how much land is louisiana losing every year as a result of coastal erosion?
Louisiana is losing about 16 square miles/year as a result of coastal erosion. This estimation is a variable as the rate of coastal erosion varies from time to time.
Coastal erosion is the process through which local sea-level rise as a result of intense wave action in coastal sea levels which deteriorate over time along the shore.
In Louisiana, coastal erosion results in the depletion of wetlands via the routes of coastal lines in swamps and marshes. Storms and other natural occurrences that induce erosion impact all coasts. The combination of storm surge at high tidal waves with additional effects from large waves, as well as circumstances often associated with landfalling tropical severe storms, provides the most devastating conditions in landfilled regions.
Therefore, the amount of landmass lost by Louisiana is estimated to be 16 square miles/year as a result of coastal erosion.

The cell membrane's function is to..
O allow nutrients in, and send wastes out of the cell
O to control the amount of water that enters the cell
O to block all nutrients from entering the cell
Answer:
The first bullet point is correct
Explanation:
The cell membrane controls what comes in and out of the cell, it needs minerals so would not block them completely, and water does not enter cells so it is clearly the first one.

Which is NOT a homeostatic mechanism?
O fecal regulation
O water regulation
oxygen regulation
thermoregulation
Explanation:
To be precise, homeostasis is a process/phenomenon not a system. Homeostasis is actually the process of maintaining a stable internal environment despite changes in the external environment. There are mechanisms in organisms that regulate pH and this regulation is an example of homeostasis.

Describe the significance of enzymes in our digestive system having different optimal pH and optimal temperatures. (Hint: What does this allow our bodies to do?)
Answer:
Digestive enzymes play a key role in breaking down the food you eat. These proteins speed up chemical reactions that turn nutrients into substances that your digestive tract can absorb. Your saliva has digestive enzymes in it. Some of your organs, including your pancreas, gallbladder, and liver, also release them.
For most enzymes to operate in the body, the optimal temperature is 37 degree Celsius or 98 degrees Fahrenheit. Most of the human enzymes have a maximal activity at pH around 7.2, which is the pH of most body fluids. However, there are exceptions such as, pepsin.

Which description of skeletal cartilage is incorrect
Fibrocartilages are able to withstand both pressure and stretch.
Costal cartilages reinforce airways and support the external nose.
Elastic cartilages are able to tolerate repeated bending.
Articular cartilages cover the ends of most bones at moveable joints.
Costal cartilages are said to be at the anterior extreme of a rib cage. Their function is to give the ribcage a flexible structure and connect the ends of the ribs to the sternum. Respiratory cartilages are present in the Trachea and are responsible for flexible inhalation and exhalation thereby reinforcing airways and providing support to the structure of the nose.
