Answer:
Postzygotic barrier
Explanation:
The reason why the species died due to genetic difference or genetic variation after the species produced zygote and begins to develop was because of what is called POSTZYGOTIC BARRIER.
POSTZYGOTIC BARRIER is a barrier or otherwise obstacles that does not allow offspring that are fertile and capable of producing a specie to form by preventing the formation after the species has begin to develop which is the development stage thereby making the already formed species to die.

Stems, roots, leaves, and bark. The three fundamental organs of vascular plants are the roots, stems, and leaves; nevertheless, these organs frequently have undergone specialization for a variety of purposes and do not appear to be "typical."
What are organs of plants?An organ is a collection of tissues that perform the same function and are located in the same place. Roots are plant organs. They firmly anchor plants and have root hair cells on their surface that absorb water and nutrients from the soil. Additional plant organs include flowers, leaves, and stems. Among these, the stems that support reproductive organs, such as angiosperm flowers and conifer cones, are the most visible. A group of tissues that collaborate to perform a specific function as a structurally sound functional unit. Plants' major organs are the leaf, root, stem, and reproductive organs. The leaf's primary function is to produce food for the plant via photosynthesis.To learn more about organs of plants refer to:

Answer:
Germline mutations, Chromosomal alterations and Point mutations.
Explanation:
Mutations in genes is responsible for causing cancer because it accelerate rate of cell division or inhibiting normal controls. Germline mutations, Chromosomal and Point mutations are the three types of mutations which causes cancer cells to develop. Germline mutations causes inherited cancer because the mutations occur in sex gametes means cancer disease inherited from parents to offspring while Chromosomal and Point mutations occur in the body not in the sex cells.

Put the last 6 (Creep to Avalanche) in order from Fastest to Slowest.
Answer:
creep, solifluction, slump, earthflow, mudflow, debris avalanche, rockfall
Explanation:
Mass movement also known mass wasting is the motion of rock, regolith (loose mixture of soil and rock particles that covers the earth's surface), snow, and ice down a slope. Based on increasing speed of movement, the given mass movement processes are as follows:
Creep- this a very slow, usually continuous movement of regolith down slope.
Solifluction - this is a sediment flow. A sediment flow is a mixture of rock, regolith with some water. The rate solifluction is measured in centimeters per year. It occurs at a faster rate than than creep.
Slumps - is a type of mass movement whereby there is a downward rotation of rock or regolith along a curved surface producing depressions or scars on the slope. It occurs at a faster rate than solifluction.
Earthflows - they usually occur with heavy rains and occur at a much faster rate with velocities between several centimeters per year and hundreds of meters per day.
Mudflows- are a highly fluid mixture of sediment and water which usually result from heavy rains in areas where there is an abundance of loose sediment. These sediments are picked up by flowing streams of water. Mudflows occur at high velocities and can travel long distances.
Debris Avalanches - These are very high velocity mass movements that result from the complete collapse of a mountainous slope. Earthquakes and volcanic eruptions usually cause debris avalanches. Avalanches involving snow only is known as snow avalanches.
Rock Falls - Rock falls occur when a piece of rock which may be large or small on a steep slope comes loose and falls down the slope. On its way down it may dislodge other rocks which also fall down the slope. Rock falls are the fastest of the six types of mass movements stated.

In the early 1900s, Thomas Hunt Morgan was among the first scientists to contribute to the chromosome theory of heredity. Morgan’s investigations into heredity in fruit flies led him to propose that the event represented in the diagram sometimes occurs.
Which statement about the event represented in the diagram is valid?
Answer:
"The genes for all organisms are composed of the same building blocks"
Explanation:
The statement about the event presented in the diagram sometimes occurs - D. The event provides genetic diversity in eukaryotic cells.
The given event in the diagram is known as crossing over which takes place during the process of meiosis.
Crossing over takes place during the pachytene stage of Prophase I of Meiosis I where the non-sister chromatids of homologous chromosomes exchange genetic material
this results in the recombination of the genetic material and creates a new genetic combination.
Thus, genetic variations occur which can be beneficial to the offspring.
Thus, the statement about the event presented in the diagram sometimes occurs - D. The event provides genetic diversity in the eukaryotic cell.
A genetic mutation causes a squirrel to be born with much darker fur than its parents.
How will this mutation most likely affect the squirrel population?
Because the trait was caused by a mutation, it will not be passed on to any offspring, resulting in the disappearance of the trait.
Because the trait was caused by a mutation, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
If the trait is unfavorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
If the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
Answer: If the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.
The mutation most likely affects the squirrel population if the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels. The correct option is D.
What is mutation?A mutation is a change or modification in the DNA or gene sequence of the organism. The modification is done due to mutagens. These mutagens delete or insert or replace the bases and cause differences.
Here, due to mutation, the color of the squirrel changed to black, so if the gene of black color will be transferred to future generations, it can be dominant or recessive.
Thus, the correct option is D, If the trait is favorable, it will be passed on to offspring over many generations, resulting in a population of darker squirrels.

A type of bacteria reproduces through binary fission every hour. What happens to the number of bacteria each hour?A type of bacteria reproduces through binary fission every hour. What happens to the number of bacteria each hour?
Since binary fission is the direct division of bacteria from which two cells result that means every hour the number of bacteria will double.
Answer:
the number of bacteria will double and 32
Explanation:
because in 1 hour its 2 and in 2 hours its 4 so it doubled or you can check in 3 hours it was 8 and in 4 hours it was 16 so it doubled. And when you double 16 do find the amount in 5 hours it is 32.
