How might an asteroid impact change earth’s climate

An asteroid hitting the earth would cause a lot of dust, ash, and other debris to go into the atmosphere which would block the sun which would cause the temperature to decrease.

What is the final acceptor of electrons in the electron transport chain?

aksik [14]

The final acceptor of electrons in the electron transport chain is "C" , that is oxygen.

The electron transport chain is composed of a series of electron carriers that operate together to transfer electrons from donors, like NADH and FADH2, to acceptors such as O2.

The electrons flow from carriers with more negative reduction potentials to those with more positive potentials and eventually combine with O2 and H+ to form water.

The difference in reduction potentials between oxygen and NADH is large, about 1.14 volts and makes possible the release of a great deal of energy.

The constancy of the chromosome number from one cell generation to the next is maintained through.

vesna_86 [32]

Through mitosis, the number of chromosomes is kept constant from one cell generation to the next.

<h3>What occurs during mitosis?</h3>

A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes. Due to the importance of this procedure, specific genes carefully regulate each phase of mitosis. Health issues like cancer may develop when mitosis is improperly controlled.

<h3>How many phases of mitosis are there?</h3>

Prophase, pro metaphase, metaphase, anaphase, and telophase are these stages.

<h3>What function does mitosis serve?</h3>

Mitosis' purpose is to divide the genome so that the two daughter cells inherit an identical and equal number of chromosomes.

<h3>Where in the cell cycle does mitosis occur?</h3>

The mitotic phase, which consists of mitosis and cytokinesis and produces two daughter cells, begins after interphase. Despite the fact that the two processes frequently overlap, mitosis occurs before cytokinesis.

A teacher has two cubes of sugar that are both the same size and shape. He adds cube A to a beaker filled with 100 mL of water,

bazaltina [42]

Answer:

Burning sugar results in a chemical reaction

Explanation:

Flammability, odor, and density are just a few examples of characteristic properties of a substance. A chemical reaction occurs when molecules interact with one another and the molecules change. For example burning sugar results in a chemical reaction because the properties of cube B changed when it was burned. This change in solubility shows that cube B must be a different substance than cube A because of the chemical reaction that occurred when cube B was burned.

g The primary detrimental effect of the presence of large amounts of biodegradable organic materials in water is ________. The p

Lelu [443]

Answer:

It causes oxygen depletion in the water

Explanation:

When the amounts of organic matter in the water are significant, the activity of aerobic bacteria and other decomposers increases.

Organic matter suffers decomposition in the presence of oxygen. Microorganisms degrade it while consuming dissolved oxygen in the process. Bacteria show fast and exponential growth, so the more organic matter, the more aerobic bacteria, and the less available oxygen in the water.

Organisms that usually inhabit these waters are affected by the lack of oxygen. Plants, algae, animals, and other invertebrates that need it to survive, find themselves limited in these environmental conditions. Eventually, they dye and contribute with more organic matter.

Little by little, sedimentation begins caused by the death of vegetables and animals, sinking in the bottom.

When oxygen disappears, anaerobic bacteria grow and act, producing fermentation.
