Answer 1

Answer:

I believe that your answer is A) Speciation.

Answer 2

Answer:

Speciation

Explanation:

Over time, genetic variations can happen when organisms adapt to new environments, weather, etc. Like that thing with bears and how they all started out the same, but as they separated, the once that lived in the cold with snow got thicker fur (polar bears) and the ones that had access to a lot of fish became really big.

2. "Natural selection is usually thought of as an agent of change in populations, but it can also act to maintain the status quo."
In a short, written response, analyze and evaluate this statement. Include the range of responses of a population to changes in the environment, such as differential reproductive success, the adaptation and development of diversity in and among species, and the change in populations.

Answers

Answer:

Those organisms survive and maintain its population who are chosen by natural selection.

Explanation:

This statement means that when the population experiences a new set of environmental conditions, two things are happened i. e. the population either adjusts through natural selection or becomes extinct. The fossil of dinosaur indicates that extinction occur due to changed in the environment. If the population made changes in itself and adapt the environment then the organism survive otherwise extinction occur.

Which hypothesis helps to explain why all organisms share the same genetic code?

Answers

RNA , RNA molecules may have been able to self-replicate without the help of other molecules. If early RNA molecules were able to copy themselves to build new RNA molecules, this helps to explain why all organisms share the same genetic code.

While looking at a cell under a microscope you notice there is no nucleus and the

chromosomes are double stranded (they have 2 sister chromatids). What phase of mitosis is

the cell probably in?

Answers

Answer:

This is the Prophase. Mitotic Prophase,

Explanation:

The process cell division where the cells divides two similar daughter cells(2n) is called mitosis. Therefore it is called a multiplication division because two daughter cells are form from a single the mother cells. Each of the daughter cells can also undergo Futher divisions.

It is the second stage fist mitotic cells division after the first phase called Interphase.

In this stage, the nuclear membrane disappear, nucleolus disintegrate and the nucleus disappeared This is followed by the constriction of the chromosome to sister chromatids.

The constricted nuclear membrane leads to the releases of the chromatids This is followed by the formation of the spindles fibers which are needed for the movement of chromosome for cross over.

other phases are Interphase Prophase Metaphase Anaphase Telephase(IPMAT)

Plate tectonics

Explanation:

Plate tectonics explains the features and movement of earth surface in the present and the past.

These plates are pieces of cracked shell that rest on the hot , molten rock of earth's mantle. The heat from the radioactive processes within the planet's inferior causes the plates to move, sometimes towards and sometimes away from each other.

These rocks collected were as a result of plate tectonics which drifted away.

if you had to choose between the phrase "natural selection gives organisms what they need" vs. "natural selection chooses traits that are most successful", which one would you choose? defend your answer.

Answers

Answer:

Natural selection gives organisms what they need

Explanation:

The species constantly evolve because of the changes around them. Natural selection gives organisms what they NEED in order to survive. "Natural selection produces organisms perfectly suited to their environments".

Species that continually evolve because of changes around them where natural selection gives organisms what they need to survive. "Natural selection makes organisms perfectly adapted to their environment".

What is Natural Selection?

Natural selection is defined as the differential survival and reproduction of individuals due to differences in phenotype which is a major mechanism of evolution, a change in the genetic properties of populations over generations.

It is the process through which populations of living organisms adapt and change where individuals in a population are inherently variable, meaning they all differ in some way. This variation means that some individuals have better adaptations to the environment than others.

Thus, species that continually evolve because of changes around them where natural selection gives organisms what they need to survive. "Natural selection makes organisms perfectly adapted to their environment".

Answer:

Uncontrollable cell division.

Explanation:

Cancer is a disease which is caused when cells division is uncontrollable and spread into surrounding cells and tissues. Mutations in genes is also responsible for the cause of cancer because this mutation accelerate the rate of cell division or inhibiting normal controls on the system, such as programmed cell death. When the mass of cancerous cells grows with the passage of time, it turn into a tumor.
