Answer:
its B. thoracic cavity.
Explanation:
it is the ventral body chamber that contains the pericardial cavity (the heart) and the pleural cavity (the lungs).
The pleural cavities and the pericardial cavity are located within the Thoracic cavity. Hence option B is correct.
What is the thoracic cavity?The heart, lungs, oesophagus, thymus, sympathetic trunk, and major vessels are all located within the hollow thoracic cavity, which is enclosed by the rib cage and the diaphragm.
The thoracic cavity serves to house and safeguards a number of the body's most important organs and structures. The sternum, costal cartilage, ribs, and the bodies of the thoracic vertebrae make up the rib cage. The rib cage supports the upper extremities, protects the thoracic cavity's internal organs, and aids in breathing.
The thoracic cavity contains the pleural cavities and the pericardial cavity. Therefore, option B is correct.

Which method of determining salinity is least likely to be used by current oceanographers?
A. Determining salinity based on measurements of the chloride ion
B. Determining salinity based on refraction of light
C. Determining salinity based on satellite observations
D. Determining salinity based on electrical conductivity of seawater using a CTD
Answer:
D
tell me if I am wrong please
Answer:
Refraction OF LIGHT
Explanation:
Salinity can be measured in various ways. Most oceanographers
measure salinity with an instrument called a CTD, named for the three
parameters it measures: conductivity, temperature, and density. To
determine salinity, probes on the CTD record electrical conductivity.
SOURCE OF ANSWER:
Desktop CTD instruments are also available, but when the
highest precision isn't necessary for lab settings, a much simpler tool
called a refractometer is used.
A refractometer measures salinity based on refraction. Refraction is the
bending of light that occurs within a water sample. Only a few drops of
water are placed under the light source of the handheld refractometer.
One challenge to understanding Earth's geologic history is
Most ancient ocean plates have been destroyed by subduction
Plate tectonics causes uplifting
Continents collide and destroy fossil evidence
There are few continental plates older than 200 million years old
Answer:
Continents collide and destroy fossil evidence
Explanation:
One main challenge in understanding earth's geologic history is that continents collide and destroy fossil evidence.
Fossils are the preserved remains of dead organisms found in rocks. They are very good and useful indicators of the life of an organism. By studying the progression of their evolution, a vivid understanding of the earth's geologic history can be constructed.What is the atomic mass (mass number) of this atom?

Using your own words, describe lapse rate.
Answer:
A lapse rate is a rate during which the temperature changes with the peak within the atmosphere.
Explanation:
sorry it took me so long :(
Answer:
The Lapse Rate is the rate that temperature changes with height in the Atmosphere. Lapse rate nomenclature is contrarily connected to the modifying itself. If the lapse rate is positive, the temperature becomes less with height; interchangeably if negative, the temperature becomes more with height.

Consider the separate stages of an animal virus life cycle. Assemble a list of structures and processes that are unique to the virus and would make good drug targets for an antiviral agent. Explain your rationale for each choice.
Answer:
Explanation:
In order to make an antiviral agent, we need to find good drug targets, that is, to find structures and processes that are only present in the virus, so there is no harm on human cells when this antiviral agent is being applied.
In the virion of a naked virus, only nucleic acid and protein are present forming the nucleocapsid. The nucleic acid and proteins of the capsid, specially, are found only in the virus and therefore make good drug targets. For example, we can express antibodies to recognize the proteins of the capsid and guide the immune system to destroy them.
Although virus particles are metabolically inert, one or more key enzymes are present within the virion in some viruses, for example, the reverse transcriptase. This enzyme is only found in viruses and if we find a way to inhibit the activity of this reverse transcriptase, like for example finding a competitor substrate, the virus will not be able to synthesize the DNA needed for its replication.
Regarding processes in the virus life cycle, they all have similar steps: first the attachment of the viral particle onto the cell, then the penetration of the virus, then the synthesis of early and intermediate enzymes using the host cell machinery, and finally the assembly of these viral components and lysis of the host cell to release new viral particles.
The attachment of a virion to a host cell is a highly specific process. Recognition proteins on the virus recognize specific receptors on the host cell. Substances that compete with the virion for these specific receptors can be used. If there is no attachment, there is no infection.

What strategy/structure prevents Na /Glucose symporters from laterally diffusing from the apical side to the lateral or basal sides of the cell?
a. Tight junctions form a ring of protein around the cell which connects to neighboring cells. This forms a physical barrier restricting lateral diffusion within the membrane.
b. The Na+/Glucose symporters are anchored to the apical side, where they are originally delivered through vesicular trafficking, through protein-protein interactions with the cytoskeleton.
c. Extracellular matrix proteins unique to the intestinal lumen side interact with extracellular side of the Na+/Glucose symporters.
d. None of these
Answer:
a. Tight junctions form a ring of protein around the cell which connects to neighboring cells. This forms a physical barrier restricting lateral diffusion within the membrane.
Explanation:
Epithelial cells in the small intestine act absorbing nutrients from the digestive tract. The cell membranes in these cells are divided into two domains: the apical domain specialized in nutrient absorption, and the basolateral domain, which transfers the absorbed nutrients to the blood vessels.
In order to maintain these functions differentiated, the mobility of proteins must be restricted to the pertinent domains. One of the mechanisms to achieve this is the formation of tight junctions between the adjacent cells of the epithelium. This acts as a barrier to the movement of lipids and membrane proteins. As a result, proteins can diffuse within their domains but can not cross from one domain to the other.
These tight junctions are formed by interactions between strands of transmembrane proteins, and generally, associate with adherent unions and desmosomes forming an union complex.

Consider what would happen to a diploid plant when genes are destroyed by a mutation.
How many genes would have to be destroyed in a diploid plant for one trait to be lost?
Answer:
Two, usually
Explanation:
A diploid plant has two copies (alleles) of every gene. If one copy of the gene is destroyed by a mutation, the plant will likely be okay with its other copy, and the trait will still be expressed.
However, some traits require both copies of the gene to be expressed. For example, if one gene is destroyed that means only half the amount of the gene product is produced. If that is not enough protein for the trait to be expressed, then the trait will be lost.

What are the function of chloragogen
Cell in earthworm
Explanation:
The cells store glycogen and neutralize toxins and are present in coelomic fluid of some annelids. They are yellowish in colour due to the presence of yellow granules called chloragosomes.
These cells are derived from the inner coelomic epithelium, and help in excretory functions, as most commonly demonstrated in earthworms.
Why was it important to drop the ball from the same height three times? Why were the numbers
slightly different?
Answer:
It is important to do this to test your theory multiple times, so that you can see what effect the drop has on it when doing this multiple times. The numbers were slightly different because the recordings will not always be the same.

Damage to the highlighted region of the spinal cord results in ________ of the skeletal muscles served by that particular region.
Answer:
Non-functioning
Explanation:
Non-functioning of skeletal muscles occurs when the spinal cord region is damaged because spinal cord is responsible for sending information in the form of signals. The spinal cord has a network of fiber started from the brain and distributed to all the body is known as neurons. These neurons are responsible for sending instructions to the muscles from brain. If they are damaged, the body parts unable to move and can't perform their particular function.
