Put the last 6 (Creep to Avalanche) in order from Fastest to Slowest.

Answers

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.

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.

Answers

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.

Answers

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.

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.

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?

Answers

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.
