Answers
Over time, these populations adapt and diverge to the extent that they are no longer able to interbreed and produce fertile offspring. This is best described as an example of Speciation.
When two groups within a species can no longer reproduce successfully to produce fertile offspring, speciation takes place. This might entail some sort of physical division and genetic divergence. Without any actual separation, it can still happen.
New species emerge through a process called speciation. It happens when populations of a species diverge and become reproductively isolated. When groups from an ancestral population undergo allopatric speciation, it is because of a period of geographic isolation that they diverge into distinct species.

A. it is not conducting an action potential.
B. more sodium ions (Na+) outside the cell than inside the cell.
C. more potassium ions inside the cell than outside the cell.
D. more sodium ions inside the cell than outside the cell.
Answers
Answer: C.
Explanation: The way the pump functions is it intakes 3 sodium ions, and spits out two potassium, so when the neuron is at rest after firing, it has to spit out all the potassium in order to intake the sodium. It will slowly intake more potassium to make up for the deficit but when at rest, the potassium concentration is higher outside the cell.

Check all that apply.
a. β-chain
b. α-chain
c. γ-chain
d. δ-chain
e. porphyrin ring
f. iron
Answers
An adult human's hemoglobin contains α and β chains, with the association of iron in a porphyrin ring. So options A, B, E, and F are correct.
The blood of an adult human contains red blood cells that have Hemoglobin. Hemoglobin as the name suggests, contains the 'Heme' part and the 'globin' part. Together, they form a quarternary structure.
The globin part is formed with the α and β chains, occurring in sets of two forming a condensed structure. The globin part holds the heme part at the center of each chain.
The heme part is formed of a porphyrin ring which associates with iron. This is very essential for the affinity of oxygen.

C) Plant body cells are produced by mitosis and cells containing 5 chromosomes are reproductive cells produced by meiosis
D) Plant body cells are produced by meiosis and cells containing 5 chromosomes are reproductive cells produced by mitosis
Answers
The correct explanation can be "Plant body cells are produced by mitosis and cells containing 5 chromosomes are reproductive cells produced by meiosis".
What is meant by meiosis?
It is a special type of cell division occurs in sexually reproducing organisms that reduces the number of chromosomes in the gametes to half of the parent cell and producing four haploid cells.
Generally, Plants undergo mitotic cell division to produce diploid parts like stem, leaf etc. But they use meiotic cell division to produce haploid parts that ultimately results in the production of egg and sperm cells which are haploid.
Both pollen mother cells and megaspore mother cells undergo meiotic division to produce sperm cells and egg for the continuation of generation. During meiotic division chromosomes are reduced to half of the parent cell.
Hence, certain parts of the plant undergo meiotic division to produce gametes and this result in the reduction of chromosomes to 5 whereas most of the parts of the plant which undergo mitotic division have 10 chromosomes.

Son consideradas biomoléculas aquellas moléculas que forman parte de los organismos vivos.
Las moléculas son las unidades físicas de la materia, que se forman a partir de la unión de dos o más átomos agrupados a través de enlaces químicos.
Las biomoléculas se clasifican en inorgánicas u orgánicas.
• Las biomoléculas inorgánicas se encuentran ampliamente en la atmósfera. El agua, algunas sales como el cloruro de sodio, y gases como el oxígeno, son ejemplos de biomoléculas inorgánicas.
• A las moléculas como azúcares, proteínas, combustibles, entre otras, las cuáles contienen átomos de carbono, hidrógeno, oxígeno y a veces nitrógeno se les llama moléculas orgánicas.
Cuando las moléculas orgánicas forman parte de la materia viva, se les conoce como biomoléculas orgánicas, las cuales incluyen fundamentalmente glúcidos, lípidos, proteínas y ácidos nucleicos.

Answers
The statement consistent with the principle of competitive exclusion is: e) Even a slight competitive advantage will eventually lead to the elimination of the less well-adapted of two competing species.
Competitive exclusion refers to the idea that two species competing for the same resources cannot coexist indefinitely. When one species has a slight advantage, it will outcompete the other species, eventually leading to the less well-adapted species' elimination from the ecosystem. This principle highlights the importance of resource partitioning and niche differentiation in allowing different species to coexist.
Therefore, (e) is consistent with the principle of competitive exclusion as it highlights the importance of even slight competitive advantages in the survival of a species.
