Why do exons have to be
spliced together?
Answers
Answer:In genetic engineering, scientists splice together genetic material to produce new genes or to alter a genetic structure. In messenger RNA , the introns are removed, and exons are spliced together to yield the final messenger RNA that is translated. See also exon intron. The American Heritage® Science Dictionary Copyright © 2011.
Explanation:
Splicing makes genes more modular which allows new combinations of exons to be created during development.
What is Splicing?Splicing is defined as the process in molecular biology where a newly generated precursor messenger RNA transcript is converted into a mature messenger RNA that functions by removing all introns and splicing the exons back together.
Splicing makes genes more modular which allows new combinations of exons to be created during evolution, where new exons can be inserted into old introns without disrupting the function of the old gene.
Thus, Splicing makes genes more modular which allows new combinations of exons to be created during development.

what material is found within the joint cavity of a synovial joint?
Answers
The material found within the joint cavity of a synovial joint is called synovial fluid. It serves as a lubricant and shock absorber for the joint.
Synovial joints are the most common type in the body, found in the knees, elbows, and shoulders. The joint cavity of a synovial joint is filled with synovial fluid, a thick, viscous substance. Synovial fluid is produced by the synovial membrane, which lines the joint cavity. Synovial fluid has several vital functions within the joint. Firstly, it acts as a lubricant, reducing friction between the articulating surfaces of the bones. This allows for smooth and painless movement of the joint. Secondly, synovial fluid nourishes the cartilage, which covers the ends of the bones in the joint. It supplies nutrients and oxygen to the cartilage cells, helping to maintain their health and function. Additionally, the synovial fluid acts as a shock absorber, cushioning the joint and reducing the impact of physical activity. It helps to distribute forces evenly across the joint, protecting the bones and other structures from excessive stress or damage.

B cell receptors are NOT: Group of answer choices complimentary in shape to a specific antigenic determinant that they may or may not encounter randomly generated with antibody variable regions that determine its BCR formed in response to an encounter with an antigen bound to the surface of B lymphocytes and have two antigen binding sites
Answers
B cell receptors are NOT randomly generated with antibody variable regions that determine its BCR.
B cell receptors (BCRs) are membrane-bound antibody molecules. They are produced by individual B cells and are unique in their ability to recognize, bind, and respond to specific antigenic determinants. B cell receptors are not randomly generated; rather, they are genetically programmed to recognize specific antigenic determinants that may or may not be encountered by the individual.
The BCR is formed in response to an encounter with an antigen, which is bound to the surface of the B cell. B cell receptors have two antigen binding sites that can each recognize and bind to a single antigenic determinant. The antibody variable regions are responsible for determining the specificity of the BCR, and they are generated by a process of gene rearrangement that occurs during the development of B cells.

at what co2 parts per million concentration and when is the bio diversity (in terms of species richness) of aquatic organisms in the indian ocean the greatest?
Answers
The biodiversity of aquatic organisms in the Indian Ocean is influenced by multiple factors, including CO2 concentration.
Iit is important to note that the relationship between CO2 concentration and species richness is complex and affected by various ecological and environmental factors. While higher CO2 concentrations can have detrimental effects on marine ecosystems, such as ocean acidification, it does not necessarily mean that the biodiversity is at its greatest at a specific CO2 concentration. Species richness in the Indian Ocean is influenced by a multitude of factors, including temperature, nutrient availability, ocean currents, and ecological interactions. It is typically highest in areas with diverse habitats, such as coral reefs, seagrass beds, and mangrove forests, where various species can find suitable niches and resources. Therefore, it is not possible to pinpoint a specific CO2 concentration at which the biodiversity of aquatic organisms in the Indian Ocean is the greatest. Biodiversity is a complex outcome of numerous interacting factors and cannot be solely determined by CO2 concentration.

A crocodile-like morphology evolved independently in a group of Triassic reptiles called phytosaurs, and later, after phytosaurs were extinct, in true crocodiles. This is an example of: Sympatric speciation. Iterative evolution Evolutionary drift Genetic drift Lamarckian evolution
Answers
The correct answer is iterative evolution. A crocodile-like morphology evolved independently in a group of Triassic reptiles called phytosaurs, and later, after phytosaurs were extinct, in true crocodiles. This is an example of iterative evolution.
Iterative evolution is the development of similar structures or forms independently over time in separate lineages. This is frequently seen in unrelated lineages of organisms that evolve similar features through convergent evolution. The crocodile-like morphology that evolved independently in Triassic reptiles called phytosaurs and later in true crocodiles is an example of iterative evolution as they evolved independently in separate lineages. The ability of the phytosaurs to thrive in an aquatic environment likely contributed to the development of this morphology, which later allowed true crocodiles to similarly thrive.

during winter, what factors can reduce the rate of photosynthesis in evergreens such as pine trees? choose all that apply
Answers
During winter, lack of water, cold temperatures and reduced sunlight reduce the rate of photosynthesis in evergreen trees such as pine trees.
Pine trees are evergreen trees in that they they are green all year as they do not lose their leaves like other trees. This is because is because they have reduced needle-like leaves which they keep all-year round.
Thus, evergreens are able to photosynthesize even in winter when other trees lose their leaves. However, the rate of photosynthesis is greatly reduced because of winter conditions.
These conditions of factors that reduce the rate of photosynthesis include:
Lack of water: during winter, water is scarce because most water freezes to form ice. As water is needed for photosynthesis, the rate of photosynthesis is reduced.Cold temperature: in very cold conditions, water in between the cells of winter evergreen trees can form ice leading to dehydration. They plants compensate for this by closing their stomata to avoid water loss through transpiration. Closing of the stomata prevents the diffusion into the cell of carbon dioxide, thus limiting photosynthesis.Reduced sunlight: sunlight which is needed for photosynthesis is reduced during winter, thus, reducing the rate of photosynthesis.Thus, during winter, lack of water, cold temperatures and reduced sunlight reduce the rate of photosynthesis in evergreen trees such as pine trees.

Answers
The statement that is incorrect about the excretory system is c. The net effect of atrial natriuretic peptide is actually to decrease blood volume and blood pressure.
Atrial natriuretic peptide is a hormone produced by the heart that promotes the excretion of sodium and water in the kidneys, which leads to a decrease in blood volume and pressure.
This is the opposite effect of angiotensin II, which is produced in response to a decrease in blood volume or pressure and stimulates sodium and water reabsorption in the kidneys to increase blood volume and pressure.
On the other hand, Aldosterone stimulates the reabsorption of sodium and water in the distal tubules of the nephron to increase blood volume and pressure.
Antidiuretic hormone is released in response to increased plasma osmolarity to promote water reabsorption in the kidneys.
The descending limb of the loop of Henle is permeable to water, while the ascending limb is not, which allows for the concentration of urine
Therefore the correct option in c.

How long does it take a freshly laid egg to hatch into a baby chicken?
Answers
A freshly laid egg takes about 21 days to hatch into a baby chicken. However, this can vary slightly depending on the breed of chicken, as some breeds may take a day or two longer or shorter to hatch.
During this incubation period, the egg needs to be kept warm and at a consistent temperature of around 99-100 degrees Fahrenheit. This can be done naturally by a mother hen sitting on the eggs, or artificially through an incubator. The egg also needs to be turned regularly to ensure that the developing chick doesn't stick to the inside of the shell.
Once the chick is ready to hatch, it will use a special egg tooth to break through the shell. This can take several hours and requires a lot of effort from the chick. Once it has hatched, the baby chicken will be wet and tired, and will need to rest and dry off before it can start exploring and learning how to be a chicken.
Overall, the process of a freshly laid egg hatching into a baby chicken is a fascinating and exciting one to watch, and it's incredible to see how much growth and development happens in just a few short weeks.

what types of organic molecules associated with cell membranes can be involved in cell-to-cell recognition?
Answers
Organic molecules associated with cell membranes can be involved in cell-to-cell recognition integral membrane proteins, carbohydrates attached to lipids or proteins in membrane.
The plasma membrane is made up of lipids and proteins, much like every other cellular membrane. The phospholipid bilayer, which creates a permanent barrier between two aqueous compartments, is the membrane's basic structural component.
These compartments are the inside and outside of the cell in the case of the plasma membrane. The particular tasks of the plasma membrane, such as the selective transport of chemicals and cell-cell recognition, are carried out by proteins embedded inside the phospholipid bilayer.
While proteins are in charge of carrying out particular membrane tasks, lipids are the essential structural components of membranes. The majority of plasma membranes are composed of around 50% lipid and 50% protein by weight, with glycolipid and glycoprotein carbohydrate components making up 5–10% of the membrane mass.
Because proteins are substantially bigger than lipids, this ratio translates to approximately one protein molecule for every 50 to 100 lipid molecules.

The product of an industrial cell population after the microorganism has largely completed its period of rapid growth and in a stationary phase (i.e. most antibiotics) Group of answer choices bioconversion primary metabolite secondary metabolite enzyme amino acids
Answers
The product of an industrial cell population after the microorganism has largely completed its period of rapid growth and in a stationary phase (i.e. most antibiotics). The product in this case is a secondary metabolite.
During the stationary phase, the growth rate of the microorganism slows down, and it starts producing secondary metabolites.
Primary metabolites are produced during the active growth phase and are essential for the organism's growth and survival.
Secondary metabolites, on the other hand, are not essential for growth but often provide the organism with a competitive advantage, such as antibiotics that inhibit the growth of other microorganisms.
In the context of most antibiotics, the product of an industrial cell population after the microorganism has largely completed its period of rapid growth and is in a stationary phase is a secondary metabolite.
