Darwin hypothesized that new species could appear gradually through small changes in an ancestral species. What experiment did he conduct to test this hypothesis?
Answer:
Darwin conducted an experiment with breeding pigeons.
Explanation:
The pigeons provided the perfect animal to test his theory of selection for quite a number of reasons including its trait diversity from wing structures to color patterns to size to flight patterns. From these experiments he concluded that by natural selection of randomly occurring traits that make species better suited for survival and reproduction, evolve in the astounding diversity of organisms on Earth today.

The diagram below represents the time a cell spends in the two main phases
of the cell cycle. In which phase does a cell spend less time?
A. Interphase
B. R phase
C. M phase
O
D. Prophase
The cell spends less time in the M phase, also known as the mitotic phase, where the actual division of the cell takes place.
What does happen during M phase?During this phase, the cell undergoes mitosis or meiosis, depending on the type of cell, resulting in the formation of two daughter cells. In contrast, the interphase is the longest phase of the cell cycle, where the cell grows and carries out its normal metabolic activities.
The R phase, also known as the S phase, is a sub-phase of interphase where DNA replication occurs. Prophase is the first phase of mitosis and is relatively short compared to the M phase as a whole.
During prophase, the chromosomes condense, the nuclear envelope breaks down, and the spindle fibers form. In metaphase, the chromosomes align at the metaphase plate.
During anaphase, the sister chromatids separate and move towards the opposite poles. Finally, during telophase, the spindle fibers disassemble, the nuclear envelope reforms, and cytokinesis occurs, resulting in the division of the cytoplasm and formation of two identical daughter cells.
In terms of the amount of time spent in each phase, interphase is the longest, accounting for about 90% of the cell cycle. M phase, on the other hand, is relatively short, accounting for only about 10% of the cell cycle. Therefore, a cell spends less time in M phase than in interphase.

Answer:
The nostrils, nasal cavity, pharynx, larynx, trachea, bronchi and bronchioles.
Explanation:
The air enters to the mouth and passes through nostrils, nasal cavity, pharynx, larynx, trachea, bronchi and bronchioles and finally reaches alveoli where the exchange of gases such as carbondioxide and oxygen. The hemoglobin takes carbondioxide gas from the cells that are present all over body to the lungs. Their this carbondioxide gas is removed from the hemoglobin and absorb oxygen. This carbondioxide gas is releases from the body on the same pathway but reverse in direction.

Which of the following best describes the producers in a terrestrial food web?
A) They are at the top of the energy pyramid.
B) They obtain their energy from consumers.
C) They are unaffected by decomposers.
D) They convert energy from the sun to chemical energy.
Answer:
The correct answer is - D. They convert energy from the sun to chemical energy.
Explanation:
In any food web, producers are the organism that can make their own food and energy by converting light energy coming from the sun into chemical energy, this process called photosynthesis.
Normally producers are green plants. These are present at the bottom of the energy pyramid as these are the highest in the number. Consumers et energy from producers by feed on them.

Why didn’t Darwin understand that genetics has passed on.
Answer:
Darwin did not know that DNA would become an important part of his Theory of Evolution. In fact, the subcategory of evolution called microevolution is completely based on DNA and the mechanism of how genetic information is passed down from parents to offspring.
Explanation:

Describe movement of molecules to maintain a healthy cell environment. Explain in details
Answer:
Very necessary for its survival.
Explanation:
Movement of molecules is very important to maintain a healthy cell environment because some molecules are required by the cell for its growth and development. Some molecules moves inside the cell environment through a semi-permeable membrane such as glucose, oxygen, potassium etc while on the other hand, some molecules are removed from the cell which are waste materials such as carbondioxide etc. If these waste materials are not removed from the cell, it greatly damaged the cell.

Deforestation occurs when large Amounts of trees are cut down and not replaced which of the following would result from deforestation
A. Decrease carbon in the atmosphere
B. Increased carbon in the atmosphere
Answer:
The correct answer is (B).
Explanation:
Deforestation occurs when large Amounts of trees are cut down and not replaced, which of the following would result from deforestation...
Increased carbon in the atmosphere
This statement is true because when trees become less abundant, the amount of oxygen being released into the atmosphere by trees via photosynthesis.
The circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.
What is Deforestation?Deforestation may be defined as the process of cutting down or eliminating trees in large numbers from our surroundings. This activity generally happens due to industrialization, wood extraction, urbanization, etc.
When the number of trees remains less in the environment due to deforestation or any other activity, the level of carbon dioxide in the atmosphere typically rises.
This is because carbon dioxide is considered the reactant of photosynthesis that is utilized by the plants along with water in the presence of sunlight and converted into oxygen.
But when the number of plants decreases, the level of carbon in the atmosphere increases, and the level of oxygen in the atmosphere decreases.
Therefore, the circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.
