A flask containing photosynthetic green algae and a control flask containing only water are exposed to a cycle of 12 hours of light and 12 hours of darkness. Which of the following statements best describes how the relative dissolved oxygen concentration in the flask with algae will compare to the control flask?
A. The dissolved oxygen in the flask with algae will not be different from the control flask at any time.
B. The dissolved oxygen in the flask with algae will always be higher.
C. The dissolved oxygen in the flask with algae will be higher in the light, but lower in the dark.
D. The dissolved oxygen in the flask with algae will always be lower.
E. The dissolved oxygen in the flask with algae will be higher in the light, but the same in the dark.
The option that correctly describes the relative dissolved oxygen concentration in the flask with algae will compare to the control flask is C. The dissolved oxygen in the flask with algae will be higher in the light but lower in the dark.
What factors can increase the amount of dissolved oxygen in water? Temperature, pressure, salinity and biological organisms are the major contributing factors that affect dissolved oxygen. If the medium contains a photosynthetic plant that too in the presence of light, then this will increase the dissolved oxygen. On the other hand, increased salinity and warm water decrease the amount of oxygen dissolved in water. As given above, the flasks containing the green algae and water are given 12 hours of light and then put 12 hours in darkness. The flask that contains the algae contains more dissolved oxygen during the light hours as algae are photosynthesis in nature and thus, they will do photosynthesis during 12 hours of lighting. But, the control flask contains only water and thus, there will be no addition of dissolved oxygen.Thus, we can conclude that flask that contains algae have more amount of oxygen dissolved than the control flask containing only water. During 12 hours of darkness, no photosynthesis occurs and hence algae containing flask will have a lower amount of dissolved oxygen.

the inclusive wealth index was created as a replacement for gdp for which reason, failure of GDP to account for literacy rate, unemployment rate, wealth, or resources within a nation
Answer:
failure of GDP to account of wealth.
Explanation:
the main reason for the creation of inclusive wealth index as a replacement for GDP because GDP can't tells us about the multi-dimensional nature of development. The inclusive wealth index measures the wealth of nations with the help of comprehensive analysis of production of a country. That is, it measures all of the assets including manufactured, human and natural capital of the country GDP is an indicator of a standard of living of a society while on the other hand, inclusive wealth index is an indicator of the wealth present in a country/

if bread is exposed to air at room temperature, fungi inevitably colonize it. what does this say about the presence of fungal spores in our environment?
Answer:
This supports the fact that fungal spores exists in the atmosphere or air
Explanation:
Fungi is a kingdom of living organisms that have distinguished characteristics from plants and animals. They propagate themselves using structures called SPORES. Some of these spores are able to withstand extreme or adverse unfavorable conditions and germinate when conditions are favorable. Most fungal spores are air-borne i.e are dispersed by air.
According to the information in this question, Fungal spores will colonize bread that is exposed to air at room temperature. This implies that fungal spores are present everywhere in the atmosphere looking for opportunities to germinate. The bread is a place conducive for fungal growth due to the presence of nutrients and a favorable temperature.

Explanation:
The forest community each with 100 individuals distributed among four different tree species (W, X, Y, and Z) would have the most relative abundant option as correct 25W, 25X, 25Y, 25Z.
Diversity is described because of the unique types/sort of lifestyles paperwork gift at the earth. Diversity plays an amazing position with the aid of using Maintain the stability of nature, law of weather, cleansing of air and water, carbon sequestration and international weather change, organic productivity, vitamins cycling, stabilize earth from erosion, and lots greater function.
Mainly variety relies upon Species richness and species evenness.Species richness is the entire quantity of various species present. Species Evenness is the abundance of every species in a community.What is species?Species are frequently described as the biggest organization of organisms wherein any people of the ideal or mating kinds can produce fertile offspring, normally through reproduction. Other approaches to defining species encompass their karyotype, DNA sequence, morphology, behavior, or ecological niche.

Serotonin (5-hydroxytryptamine, 5-HT) is a neurotransmitter with receptors (5-HT receptors) located in cells throughout the body.
a. True
b. False
Answer:
a. True
Explanation:
Serotonin receptors are G protein-coupled receptors involved in the modulation of both excitatory and inhibitory neurotransmission. Serotonin receptors are divided into seven classes (5-HT1 to 5-HT7) which can be in turn divided into several subclasses (A, B, C, etc.). Most of the serotonin receptors are located in the gut (about 90%), but they are also spread in other parts of the body, including the amygdala, the bed nucleus of the stria terminalis (BNST, also known as the extended amygdala), Merkel cells (skin), taste receptor cells (tongue), Raphe nuclei (brainstem), etc.

Select the statement below that describes a critical finding of the Franklin DNA diffraction experiment. Group of answer choices That the phosphate groups are stabilized by the presence of divalent metals in solution That base stacking is the primary force holding the DNA helix together That B-form DNA helices have a pitch of approximately 34 angstroms That the DNA bases are predominantly found in their keto form That the number of adenine residues is always equal to the number of thymine residues in a double stranded DNA molecule
Answer:
That B-form DNA helices have a pitch of approximately 34 angstroms
Explanation:
Rosalind Franklin was an X-ray crystallographer whose work contributed to the discovery of the molecular structure of DNA molecule by Watson and Crick. B-form DNA is the most common form of DNA, which consists of a right-handed double helix. B-form DNA was discovered by Watson and Crick based on the X-ray diffraction image of DNA (popularly known as image 51) obtained by Franklin. The pitch refers to the distance after every 10 base pairs along the DNA helix for one complete double-helix turn. This distance in the B-DNA helix is 34 Ångströms (i.e., 3.4 nanometers).

If a trait has two possible outcomes and one is expressed over the other, it means one is dominant and the other is recessive. Dominant traits are expressed when there is at least one dominant allele (can be Aa or AA). Recessive traits are expressed only if both the alleles are recessive (has to be aa). If the trait is being expressed over the other one it is a dominant trait.

Which of the following processes releases energy to be used by a cell
Answer:
A phosphate group is removed from ATP to form ADP
ATP usually releases energy by breaking down the weak phosphate cell present. The energy released due to the breaking down of the phosphate cell is then utilized. The ATP is converted to ADP. Whenever a cell feels the necessity for energy it releases a phosphate to gather the energy.
