how would you explain the formation of two subspecies of an organism from an original species
Answer:
splits into two or more genetically distinct descendant populations
Explanation:
New species form by speciation, in which an ancestral population splits into two or more genetically distinct descendant populations. Speciation involves reproductive isolation of groups within the original population and accumulation of genetic differences between the two groups
what is the main product or purpose of photosynthesis?
Answer:
Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

what is the name of the trait that hides or masks another genetic trait?
A dominant trait is the name of the trait that hides or masks another genetic trait.
What do you mean by dominant trait?Dominance is the phenomenon of one variant of a gene on a chromosome masking or overriding the effect of a different variant of the same gene on the other copy of the chromosome.
The dominant trait is the one that is the first to appear or express itself visibly in the organism. Example: In human beings, we observe V-shaped hairline.
Dominant individuals are often most influential in their social groups, affecting movement, opinion, and performance across species and contexts.

Epidemiology studies health-related states and occurrences (not simply diseases) in specific communities.Therefore, option (A) is correct.
What is epidemiology?The study and analysis of the distribution, patterns, and determinants of health and disease conditions in a given population is what epidemiology is all about. It is one of the most important aspects of public health, and it influences both policy decisions and evidence-based treatment by determining the factors that put people at risk for disease and setting goals for preventative medical care.
Descriptive, analytical, and experimental methods are the three primary approaches utilized in epidemiology. Descriptive epidemiology is the method that is utilized the most to investigate the occurrence of disease, despite the fact that all three can be employed to do so.
Therefore, option (A) is correct.

The illustration below represents____,
which is responsible for genetic diversity.
Answer: Crossing over
Explanation: This is what a crossing over gene looks like it starts together and separates here is evidence below ⬇️
The illustration below represents the crossing over stage in meiotic cell division which is responsible for the genetic diversity in organisms. Thus, the correct option is B.
What is Crossing over?Meiosis is the type of cell division during which the chromosome number in the daughter cells become half of that present in the parent cells from which they are produced. From one parent cell four daughter cells are formed in meiosis.
Chromosomes forms the chromatids in the cell which form tetravalent with the non-sister chromatids of the homologous chromosomes. This stage is called crossing over where the genetic material present in each of the chromatids are exchanged which results into genetic diversity in a species. After the crossing over stage, the chromatids separate from each other and goes to different daughter cells.
Therefore, the correct option is B.

best explanation of the role of dna and rna in making proteins?
Answer:
DNA stores the information for protein synthesis, and RNA carries out the instructions encoded in DNA.
DNA stores the information for protein synthesis, and RNA carries out the instructions encoded in DNA.
What is protein synthesis?
Cells create proteins through a process known as protein synthesis. Transcription and translation take place simultaneously. The conversion of genetic information from DNA to mRNA in the nucleus is known as transcription.
Initiation, elongation, and termination are its three stages. Following processing, the mRNA transports the instructions to a ribosome in the cytoplasm.
The ribosome, which is made up of proteins and rRNA, is where translation happens. The mRNA's instructions are read during translation, and tRNA then transports the appropriate sequence of amino acids to the ribosome. rRNA then facilitates the formation of bonds between the amino acids, resulting in a polypeptide chain.
A polypeptide chain may be further processed to create the finished protein after it has been created.
Therefore, DNA stores the information for protein synthesis, and RNA carries out the instructions encoded in DNA.

cellular respiration how cells harvest energy
Answer:
Cellular Respiration: a process able to extract a large amount of energy from food molecules. In eukaryotic cells oxygen is a required component. This metabolic process is the main reason that animals have elaborate gas exchange organs such as lungs, gills and other systems. The goal of these systems is, of course, to get access to oxygen and to get rid of carbon dioxide.

kinetic energy is needed by the molecules in order to escape from the surface.
All the water molecules in the liquid are moving randomly due to the presence of some energy in it. Some of the molecules have more kinetic energy due to absorption of heat energy from the surrounding environment.
Due to high kinetic energy, these molecules move enough to escape the surface of the liquid. This is called boiling point. This makes the liquid become gas so we can conclude that kinetic energy is needed by the molecules in order to escape from the surface.

In the area illustrated, what process is evident over time?
In the area illustrated in the image attached, the biological process which is evident over time is: ecological succession.
Ecology can be defined as the scientific study of the relationship existing between living organisms such as plants and animals with respect to their physical and biological environment (abiotic factor).
In Ecology, ecological succession refers to a process through which the structure of an ecological (biological) community evolves or changes over time.
Generally, there are three (3) main types of ecological succession and these include:
Primary successionSecondary successionCyclic successionFrom the ecological (biological) community illustrated in the image attached, we can deduce that there is an evolution (change) in the species of plants growing over time. This ranges from weeds during the first visit to pine and oak trees during the seventh visit.
