Which stage is the last stage of speciation? question 5 options: the populations become adapted to different environments and ev
insens350 [35]

Answer:

D) The population become adapted to different environments and eventually becomes so different that they cannot interbreed to produce fertile offspring.

Explanation:

Speciation is divided into three stages:

a) Separation.

b) Adaptation.

c) Reproductive Isolation.

Stage 1: Separation.

A part of the population separates and adapts to a new environment. Natural events such as tsunamis, tidal waves can cause organisms to separate from their initial habitat to a new environment.

Stage 2: Adaptation.

At this stage, the organisms evolve new traits that enable them to a new environment. They possess certain characteristics that enable them to fit into the new environment. Example The great white skin's color makes it difficult for it to be seen in the dark.

Stage 3: Reproductive Isolation.

At this stage, organisms of the same species reunite and do not interbreed. Here, species are isolated into new ones so they have the best adaptations for their new habitat.

What is the length of ? round to the nearest tenth. 9. 7 m 10. 4 m 37. 3 m 38. 6 m.
REY [17]

The length of x to the nearest tenth is; D: 38.6 m

<h3>Trigonometric ratios</h3>

The image of the triangle is missing and so i have attached it.

From the image attached, we can find the value of x by using trigonometry ratio.

We see that;

  • AB = x
  • AC = 10
  • ∠BAC = 75°

Thus;

10/x = cos 75

10/x = 0.2588

x = 10/0.2588

x = 38.64 m

Approximating to the nearest tenth gives;

x = 38.6 m

An experiment was conducted to determine whether the price of a golf club affected the distance a golfer could hit a golf ball.
IceJOKER [234]

The true statements about the data from the t-test will be:

  • The data was collected using random assignment, the golfers were assigned randomly to the two groups.
  • The data was also collected using random selection.
  • The distribution of the difference in the sample means will be normally distributed as well according to the central limit theorem.

<h3>What is a t-test?</h3>

A t-test simply means a type of inferential statistic that is used to determine if there is a significant difference between the means of two groups,

From the complete question, the data was collected using random assignment, the golfers were assigned randomly to the two groups, it was also collected using random selection and the distribution of the difference in the sample means will be normally distributed.

In this experiment, you will use universal indicator to qualitatively measure ph. The universal indicator in this experiment is
adell [148]

The true statements is that the color of the indicator relates to the hydrogen ion concentration of the solution.  

<h3>What does the color change tell you about the pH?</h3>

If a solution is acidic or basic, it can be measured using the pH scale. The universal indicator is said to be added into a specific solution, the color change therefore shows the estimate of the pH of the solution.

An Acid often makes universal indicator solution to change from green toward red and their solution's pH is one that is below 7 on the pH scale.

Note that pH indicators are said to be weak acids and they show the concentration of H+ (H3O+) ions in a solution through color change.

See options below

Select all of the following statements that are true about the universal indicator used in this experiment

The color of the indicator relates to the hydrogen ion concentration of the solution.

At pH 7 the indicator will be colorless.

The universal indicator (or parts thereof) are in equilibrium and have an associated K value.

The color of the indicator relates to the neutral ion concentration in solution.

The universal indicator is a single chemical compound.
