Answer:

I believe that the answer would be: Evolution of the fruit fly over time (A)

Explanation:

As we can see, the fruit fly shown is the only fruit fly we are observing. Therefore, we need to determine how it has different cells among other cells. This is where evolution would come into the picture. The reason this fruit fly has different cell structures and functions is because, over time, their bodies and makeup have changed, leaving behind these "older" cells that are now dominated by the newer ones. So, evolution is the reason why the fruit fly has different cell structures and functions.

Just like how us humans have wisdom teeth in our mouths that are not necessary because our mouths have evolved to be smaller; there isn't enough room for them to grow, in some cases.

Answer:

Radiocarbon dating involves finding the age of an ancient fossil by measuring its carbon-14 content. Carbon-14 (radiocarbon), is a naturally occurring radioactive isotope that forms when cosmic rays in the upper atmosphere strike nitrogen molecules, which then oxidize to become carbon dioxide.

DNA replication needs to occur because existing cells divide to produce new cells.Each cell needs a full instruction manual to operate properly. So the DNA needs to be copied before cell division so that each new cell receives a full set of instructions!

Answer:

Net 2 NADH, 2 ATP , 4 CO2, 2 FADH2

Explanation:

The correct products of the Krebs cycle after 1 molecule of glucose is ( option 4 ) ; Net 2 NADH, 2 ATP , 4 CO2, 2 FADH2

The Krebs cycle is a cycle/series of chemical reactions utilized by aerobic organisms in the generation of energy that is stored in phosphate bonds (ATP) through oxidizing acetate ( gotten from  carbohydrates, fats and protein) into [tex]CO_{2}[/tex].

Hence when 1 molecule of glucose through the Krebs cycle the correct products will be Net 2 NADH, 2 ATP , 4 CO2, 2 FADH2

Answer:

Calcium signaling is the use of calcium ions (Ca2+) to communicate and drive intracellular processes often as a step in signal transduction. Ca2+ is important for cellular signalling, for once it enters the cytosol of the cytoplasm it exerts allosteric regulatory effects on many enzymes and proteins. Ca2+ can act in signal transduction resulting from activation of ion channels or as a second messenger caused by indirect signal transduction pathways such as G protein-coupled receptors.

Answer:

Should be D

Explanation:

The one that is not one of the four systems into which scientists divide earth is hemisphere. The correct option is B.

The four main subsystems of the Earth are the land, the water, the living beings, and the air. The term "spheres" refers to these four subsystems.

They are the "geosphere" (land), "hydrosphere" (water), "biosphere" (life) and "atmosphere," specifically (air).

The biosphere, geosphere, hydrosphere, and atmosphere are the spheres. Together, they are in charge of establishing and preserving the Earth's climate, geological processes, and life.

The main significance of the hydrosphere is that it supports a variety of life forms, is crucial to ecosystems, and regulates the atmosphere. All of the water on the Earth's surface is covered by the hydrosphere.

Thus, the correct option is B.

Answer: Fewer sugars will be made because plants use carbon dioxide in photosynthesis.

Hope this helps

Plants are autotrophs, which prepare their food in the presence of sunlight, water, and carbon dioxide to yield sugar and oxygen.

The carbon dioxide is removed from the plant's environment, then less sugar will be produced.

Photosynthesis is a metabolic process in which plants prepare food in the presence of sunlight, carbon dioxide, and water. The products of photosynthesis are oxygen and sugar molecules.

The carbon dioxide if removed or reduced from the plant's environment, then the plants will be unable to perform photosynthesis properly, and in the limited resources, the products formed will be reduced.

Thus, the correct answer is Option A.

Answer:

data

Explanation:

All the facts and observations gathered in an experiment are called data. Therefore, option B is correct.

An experiment is a technique used to confirm or deny a hypothesis, as well as assess the likelihood or effectiveness of something that has never been tried before. Experiments show what happens when a specific factor is modified, which sheds light on cause-and-effect relationships.

The three primary categories of scientific experiments are quasi-experimental, observational, and experimental (non-experimental). The most rigorous type of scientific investigation is experimental, often known as randomized control. The most control is present, as the name would imply.

Data are the facts and the observations gathered in an experiment.  Therefore, option B is correct.

Answer:

Explanation:

Answer:

Deletion mutations can affect the entire base sequence.

Explanation:

Answer:

Deletion mutation may cause a shift of base sequence, causing the reading frames for base sequence to change during translation. This may affect the type of amino acid it the original base sequence codes for, resulting in a change in amino acid sequence in the polypeptide translated. Therefore, affecting the whole protein itself. There may be wrong amino acids that prevents vital bonds like disulfide bridges to form, resulting in a huge change in 3 dimensional conformation of the protein. A point mutation may result in a gene sequence being edited. However, only the target sequence is being mutated. The rest of the gene sequences are left untouched. Therefore, the impact is localised. This ensures that even though a few wrong amino acids may be in the polyleptide, most of the bonds that are crucial for the correct 3 dimensional conformation is still present, therefore, lesser defects will be resulted due to point mutation as compared to deletion mutation.

I think it would be d.

Explanation:

Answer:

The correct answers are options B. "It is formed at zones of volcanic activity on the ocean floor. ", C. "It is made of all types of rocks" and E. "It contains silicate minerals high in iron and magnesium."

Explanation:

In Geology, the continental crust is defined as the layer of the Earth that allowed the formation of the continents. This layer is made of all types of rocks, including igneous, metamorphic, and sedimentary rocks. This layer is also considered silica-rich, or felsic, because of its high content of silicate minerals. Regarding the thickness of continental crust, it is between 25 to 70 km thick. This is considerable thick considering that oceanic crust which barely reaches 10 km thick.

The ocean life would die off because less salinity in the water and if the currents decrease in strength the nutrients they carry would not make to the life in the oceans and ocean life would die.
