The trait for spore color is determined by more than one gene.
C.
The allele for black spores is dominant over that for white spores.
D.
The allele for white spores is dominant over that for black spores.
Answer:
C.

A genotype is an organism’s set of heritable genes that can be passed down from parents to offspring. The genes take part in determining the characteristics that are observable in an organism, such as hair color, height, etc. An example of a characteristic determined by a genotype is the petal color in a pea plant. Phenotype is the term used in genetics for the composite observable characteristics or traits of an organism. The term covers the organism's morphology or physical form and structure, its developmental processes, its biochemical and physiological properties, its behavior, and the products of behavior.
Once a protein is made, its biochemical and structural properties play a role in producing option a. phenotype.
Phenotype is the observational traits or characteristics of an individual organism. This is an aspect that includes the morphology and the physical form of an organism.
Phenotypes are produced as genetic material that is Chromosomes and DNA are produce proteins, and once the protein is prepared, then proteins, contribute to the structural properties of the cell to make physical form or phenotype.

In the lumen of the proximal tubule, Na concentration is ________ the Na concentration inside the cells of the tubule wall.
Answer:
The correct answer is - higher than
Explanation:
In the lumen of the proximal tubule of the kidney, most of the solutes are absorbed in the form of sodium. There is a gradient of sodium ions which allows the absorption of the solutes from the lumen into the cell.
It is due to the solute or Na concentration is higher in the lumen than Na concentration inside the cells of the tubule wall. So movement of the solutes is due to the concentration gradient.

Answer:
Estuaries is a water body where freshwater from rivers and streams combines with salt water that is coming from the ocean.
Explanation:
Estuaries is a type of water body that is partially enclosed present at the coastal side where freshwater from rivers and streams combines with salt water that is coming from the ocean. Shallow estuary waters create unique habitats for organisms living there because the presence of brackish water refers to the mixture of fresh water draining from the land and salty seawater. The salinity in water change as you move from inland areas out towards the ocean because the water of inland has less salt in it while water of ocean has huge amount of salt present in it so when we move from inland to the ocean salt concentration increases in it. estuaries provide protection for inland areas by filtering pollutants, prevent shoreline erosion, flooding and storm.

10 POINTS !!! Why is it risky to build something whose natural frequency can be matched by
external vibrations?
Answer:Most objects have at least one natural frequency of vibration. If a nearby object vibrates at the same frequency, it can cause resonance. Resonance is an increase in amplitude of a vibration that occurs when external vibrations match an object's natural frequency.
Explanation:
It is risky to build something whose natural frequency is matched with external vibrations because of ; The effect of resonance
When an object constructed has a natural frequency which is equal to the frequency of a nearby external vibration, the amplitude of the vibration of the object will increase due to the resonance effect which occurs because the external frequency matches up with the natural frequency of the constructed object.
The negative effect of resonance is the increase in the amplitude of the vibration of the object which might lead to the partial or complete collapse of the constructed object.
Hence we can conclude that It is risky to build something whose natural frequency is matched with external vibrations because of ; The effect of resonance

Explain how it is possible for nutrients to be transported to the cells of a flatworm with no circulatory system.
Answer:
Flatworms are beings that do not have a heart, veins, arteries, capillaries, hemolymph, or some type of circulatory fluid. Their circulation occurs between cells or intercellularly and they are responsible for transporting substances by diffusion from cell to cell.
Explanation:
Flatworms are considered multicellular eukaryotic organisms. This implies that in their cells they have a cellular nucleus, in which the DNA is contained, structuring the chromosomes. Likewise, they are made up of several types of cells, each one specialized in a specific function. They lack a structured circulatory system as such. Because of this they do not have specialized structures such as a heart or blood vessels, however, the circulation of certain substances is established between their cells. This is done thanks to the diffusion process. Substances pass from one cell to another through this process.This does not apply to all flatworms, since in some species of bog and digenae there is a certain organization and some very small conducting vessels known as the endolymphatic system, the which forms a kind of plexus in the parenchyma.It should also be noted that some species do not even have a digestive system, being the digestive tract the one in charge of digestive functions and the distribution of the nutrients they receive.

Movement of individuals into or out of the population, called gene flow, impacts evolution of populations because:_________.
a. it can lead to extinction of one or more populations.
b. it may cause genetic drift.
c. it leads to a redistribution of alleles
d. adaptive radiation results.
e. a founder effect will occur.
Answer:
c. it leads to a redistribution of alleles
Explanation:
The gene flow can be defined as the movement of genetic material from one population to another within the same species. This movement may be associated 1-with the migration of individuals and subsequent reproduction of these organisms in the new population or 2-with the movement of gametes (eg., pollen dispersal) among populations. In both cases, gene flow is known to alter the frequency of particular alleles between populations and consequently also modify the evolutionary patterns of these populations.
Gene flow is the migration of genes or alleles and refers to the transfer of the genetic material. If the rate of the gene flow is high then two populations will say to be an effective population.
It just leads to redistribution of the genes or alleles with the in the popualtion of species. Hence the option C is correct.Learn more about the individuals into or out of the population, called gene flow.

Distinguish the types of forgetting: anterograde amnesia, retrograde amnesia, encoding failure, retrieval failure, and interference (both retroactive and proactive).
Answer:
Anterograde amnesia is the inability to create new memories after the onset of amnesia, while memories from before the event remain intact. Brain regions related to this condition include the medial temporal lobe, medial diencephalon, and hippocampus. Anterograde amnesia can be caused by the effects of long-term alcoholism, severe malnutrition, stroke, head trauma, surgery, Wernicke-Korsakoff syndrome, cerebrovascular events, anoxia, or other trauma. Retrograde amnesia is the inability to recall memories made before the onset of amnesia. Retrograde amnesia is usually caused by head trauma or brain damage to parts of the brain other than the hippocampus (which is involved with the encoding process of new memories). Brain damage causing retrograde amnesia can be as varied as a cerebrovascular accident, stroke, tumor, hypoxia, encephalitis, or chronic alcoholism. The there is encoding failure. Encoding is the process of converting sensory input into a form able to be processed and stored in the memory. However, this process can be impacted by a number of factors, and how well information is encoded affects how well it is able to be recalled later. On the other hand, retrieval failure is the failure to recall information in the absence of memory cues. Proactive interference occurs when old memories hinder the ability to make new memories. In this type of interference, old information inhibits the ability to remember new information, such as when outdated scientific facts interfere with the ability to remember updated facts. This often occurs when memories are learned in similar contexts, or regarding similar things. It’s when we have preconceived notions about situations and events, and apply them to current situations and events.Retroactive interference occurs when old memories are changed by new ones, sometimes so much that the original memory is forgotten. This is when newly learned information interferes with and impedes the recall of previously learned information. The ability to recall previously learned information is greatly reduced if that information is not utilized, and there is substantial new information being presented. This often occurs when hearing recent news figures, then trying to remember earlier facts and figures.
