Peppered moths come in two color variations, as shown below.

Prior to the Industrial Revolution, the majority of the population in England consisted of the light colored variation. The dark colored moth became the dominant variation by the end of the 20th century and remained so for almost 100 years. Today, the light colored variation is dominant again.

What is the best explanation for this?

A. Populations with two variations have a better chance of survival than populations with more.

B. A single variation can be beneficial under some conditions and harmful under other conditions.

C. One variation will always be harmful, and the other will always be beneficial.

D. A single variation can be beneficial in all conditions or harmful in all conditions.

Answers

The answer, I do believe, should be option B. Here's my reasoning...

The question doesn't ask about a bunch of other species and how the moth variations relate to the survivability of many species, so I think that rules out option A. Option C is too black-and-white, because the explanation above simply states how a moth was able to survive better on different color variations. The last option, D, is also too black-and-white. So I believe that the answer is B, because sometimes, like prior to the Industrial Revolution, the one variation is better (as seen in the upswing of dominance in different variations).

16. Which statement best describes the way that
an adenosine diphosphate (ADP) molecule
becomes an adenosine triphosphate (ATP)
molecule in the human body?
C
A. Protein causes phosphate molecules to bind to
Sugars and form ATP.
B. Food energy is used to attach a phosphate
molecule to an ADP molecule.
C. lonized oxygen in cells causes sugars and
phosphate molecules to form ATP.
D. Water breaks down ADP molecules which form
into ATP molecules over time.

Answers

Option B is the correct one -

B. Food energy is used to attach a phosphate molecule to an ADP molecule

An adenosine diphosphate (ADP) molecule evolves an adenosine triphosphate (ATP) molecule in the human body B. Food energy is utilised to tie a phosphate molecule to an ADP molecule.

How does ATP store its energy?

ATP or Adenosine triphosphate acts as the energy of the cell.

It keeps the energy released in the oxidation of glucose during cellular respiration.

ATP is split into ADP and Pi and energy is freed.

Thus, option "B" Food energy is used to attach a phosphate molecule to an ADP molecule.

Part of a community

Part of an Ecosystem

In a California kelp forest, the garibaldi, the purple sea urchins, and the rocks make up part of a community and part of an ecosystem. Therefore, option B and C are correct.

What is ecosystem ?

All the organisms and the physical setting they interact with make up an ecosystem. The nutrition cycles and energy flows connect these biotic and abiotic elements. Photosynthesis is how energy enters the system and is absorbed by plant tissue.

Abiotic variables, or nonliving components, coexist with biotic components in ecosystems. Plants, animals, and other species are biotic factors.

Healthy ecosystems maintain our soil, clean our air, control the climate, recycle nutrients, and give us food. They offer resources and raw materials for making medications and other things. They support our economies and are the cornerstone of all civilizations.

n a strain of tomato plants, short plant height and small fruit size are traits that display autosomal recessive patterns of inheritance. To investigate whether the traits segregate independently, researchers cross a pure-breeding line of tall tomato plants that have large fruits with a pure-breeding line of short tomato plants that have small fruits. The researchers observe that all the plants in the F1 generation are tall and have large fruits. The researchers cross the F1 plants with one another to generate an F2 generation. The researchers record observations for the F2 generation and will use the data to perform a chi-square goodness-of-fit test for a model of independent assortment. The setup for the chi-square goodness-of-fit test is shown in Table 1.The researchers choose a significance level of p=0.05. Which of the following best completes the chi-square goodness-of-fit test?

Answers

For researchers who choose a significance level of p=0.05, the chi-square value, the critical value is mathematically given as

9.24, 7.82.

What is chi-square goodness-of-fit test?

Generally, The Chi-square goodness of fit test is simply defined as a hypothesis test that determines if a variable will originate from a certain distribution.

In conclusion, The calculated chi-square value is will be 9.24, given the significance level.

Identify the sedimentary rock composed of halite and explain how this rock is usually formed.

Answers

Rock Salt - Crystals from chemical precipitates and evaporites.

The sedimentary rock composed of halite is known as rock salt, and it is usually formed by the process of evaporation, and rock salt is formed in environments where there is a high concentration of salt in water.

What is rock salt?

Rock salt is formed in environments where there is a high concentration of salt in water, such as salt lakes, shallow seas, or salt pans, and when the water in these environments evaporates due to high temperatures and low precipitation, the dissolved salt in the water is left behind and forms deposits. These deposits can be buried by sediment over time and eventually become compacted and cemented to form rock salt. Rock salt is made up almost entirely of the mineral halite, which is composed of sodium and chlorine ions.

Hence, The sedimentary rock composed of halite is known as rock salt. It is usually formed by the process of evaporation.
