Carbon dioxide is needed by photoautotrophs to produce organic matter.

All terrestrial and marine food webs receive carbon through autotrophs, or self-feeders. Almost all of these autotrophs, like plants or algae, are using photosynthesis process.

Autotrophs use bicarbonate ions from water or carbon dioxide from the air to create organic compounds like glucose. The organic molecules are consumed by heterotrophs, or other feeders, like humans, and the organic carbon is transferred through food webs and chains.

Carbon dioxide return to the nature through a process known as cellular respiration, autotrophs and heterotrophs break down carbon-containing compounds like sugars to liberate the energy they contain. The carbons in the molecule are liberated as carbon dioxide during this reaction. When decomposing dead creatures and waste materials, decomposers also emit organic chemicals and carbon dioxide.

Water moved inside the bag in response to the water potential causing a change in the size of the bag.

The term term water potential refers to the energy required to transport a small amount of water across a boundary.

We must note that water potential is responsible for the movement of water into the bag resulting in its change of shape as shown. Water moved inside the bag in response to this potential.

Learn more about water potential: https://brainly.com/question/23855783?

The bag changed its shape because water moved from the side with a higher water potential to the bag interior, where there is a lower water potential.

Osmosis is the simple passive transport of water molecules that occurs when two dilutions of different concentrations -in this example, the interior of the Visking bag and water- are separated by a semipermeable membrane.

The membrane allows the pass of water but not solute (sugar). Hence, water can move from the most diluted side to the less diluted one. This is, from the side of the membrane with higher water potential, to the side with lower water potential.

Let us remember that the water potential is the potential energy in a mass of water. Among other factors, it depends on solute concentration,

In the exposed example, water tends to go from the hypotonic solution (higher water potential) to the bag interior (lower water potential) and keeps doing so until concentrations are equal in the bag interior and exterior.

The bag has changed its shape because as water moved, the bag began to enlarge and became bigger-sized.

Explanation:

Answer: The correct option is D ( Cells undergo fermentation because pyruvate cannot be metabolized to proceed into the Krebs cycle).

Explanation:

Pyruvate dehydrogenase is the enzyme that converts pyruvate to acetyl CoA which enters the Krebs cycle in glucose metabolism. The deficiency of Pyruvate dehydrogenase can be caused by genetic origin most commonly linked to a mutation in the a -subunit of the mitochondrial enzyme that causes the enzyme to cease functioning. As a result of the mutation, affected individuals build up dangerous amounts of lactic acid.

The increase in the level of lactic acid occurs due to the Increased action of lactate dehydrogenase enzyme. In the absence of Pyruvate dehydrogenase enzyme, the level of blood pyruvate increases. Excess pyruvate is then converted to lactic acid by lactate dehydrogenase enzyme in a process called lactic fermentation. This results in a buildup of lactic acid in the blood leading to a condition called lactic acidosis .

Therefore, cells undergo fermentation because pyruvate cannot be metabolized to proceed into the Krebs cycle.

Answer: Emigration

Explanation:

Answer:

Glycolysis is a series of reactions that take place in the cell cytoplasm. It involves the oxidation of glucose into pyruvate (a 3 carbon compound), that produces (overall)ATP and reduced NAD: an enzyme that carries hydrogen. The number of carbons in each of these compounds is indicated in the green circle.

The carriers FAD and NAD bring the hydrogen and it separates to H+ and electrons (e-). The electrons pass from carrier to carrier and loose energy. This is used to synthesize ATP.

However, there are a lot of hydrogen ions, that unless they are removed, they'll cause a large increase in pH. Therefore, oxygen reacts with the ions to remove it and produce water. This is what the oxygen you inhale is used for (in terms of respiration).

The stages of bee development are egg, larva, pupa, and adult. Eggs hatch into larvae, which then transform into pupae. Finally, adult bees emerge and undergo further maturation.

The stages of bee development are:

1. Egg: The bee life cycle begins when the queen bee lays an egg in a honeycomb cell.

2. Larva: The egg hatches into a larva, which is a legless, grub-like creature. The larva is fed a special diet called royal jelly, which stimulates its growth.

3. Pupa: The larva undergoes metamorphosis and transforms into a pupa. Inside the sealed cell, the pupa undergoes various changes, developing into an adult bee.

4. Adult Bee: After completing the pupal stage, the fully developed adult bee emerges from the cell. The bee then undergoes further maturation, such as its exoskeleton hardening, wings expanding, and adult coloration appearing.

It's important to note that there are three castes of bees: queen, worker, and drone. The development process for each caste is similar, but the diet and size of the cells they are raised in differ, leading to their distinct roles within the colony.

The purpose of natural selection is not a conscious or intentional one, as it is not driven by a specific goal or purpose. Instead, natural selection is a fundamental process in biology that acts on heritable traits within populations over generations. It is a key mechanism of evolution.

Explanation:

The primary outcome of natural selection is the adaptation of organisms to their environment. Individuals with traits that are advantageous in a particular environment are more likely to survive, reproduce, and pass on those beneficial traits to their offspring. Conversely, individuals with traits that are disadvantageous are less likely to survive and reproduce, leading to a reduction in the frequency of those traits in the population over time.

Natural selection, therefore, acts as a filter that shapes the characteristics of populations, favoring traits that enhance an organism's survival and reproductive success in a given environment. Over many generations, this process can lead to the development of new species or the modification of existing ones, as populations accumulate adaptations that allow them to thrive in different ecological niches.

It's important to note that natural selection does not have an end goal in mind, nor does it necessarily lead to the "best" or most advanced organisms. Instead, it is a consequence of the interactions between organisms and their environment, constantly shaping and refining the traits of living beings based on their ability to survive and reproduce.

The control variable is also referred to as standardized variable. It is the variable that remains constant in the experiment. The control solution in the experiment is NaHCO3 solution.
