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.

Answer:
H dominant
Explanation:
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.

A template strand of DNA in a gene reads:
TCT CCA AGC 5
Using the codon chart below, what is the sequence of amino acids that is produced after translation?
Choose 1 answer:
A Ser - Gly - Leu
B Arg - Ser - Gly
C Arg - Gly- Ser
D Ser - Gly - Gly
The sequence of the amino acids that is produced after translation of the template strand of DNA "TCT CCA AGC" is Arginine-Glycine-Serine. Thus, the correct option is C.
What is Codon?A codon is the set of a three-nucleotide sequence in a row that counts as a triplet which codes for a single amino acid in a peptide. Codon was first discovered by Marshall Nirenberg and Heinrich J. Matthaei.
The codon sequence encodes three different amino acids which have the mRNA sequence corresponding to DNA sequence "TCT CCA AGC" is "AGA GGU UCG" in this sequence AGA encodes for arginine, GGU encodes for Glycine, and AGC encodes for Serine amino acid.
Therefore, the correct option is C.

The aquarium water and air pumped into the aquarium provide what component of an ecosystem?
А
biotic
B
abiotic
С

D
decomposer
Answer: Abiotic
Explanation:
The aquarium water and air pumped into the aquarium provide an abiotic component of an ecosystem. Therefore, option B is correct.
What are ecosystems and their components?A biological community of living things that interacts with the surrounding environment and other nonliving elements is referred to as an ecosystem. It can also be described as the series of interactions or communications between living things and their surroundings.
There are two parts to any ecosystem: biotic and abiotic components. Abiotically refers to non-living items, whereas biotic components refer to all live organisms in ecology. The equilibrium in the environment is maintained by these biotic and abiotic interactions.
Thus, the aquarium water and air pumped into the aquarium provide an abiotic component of an ecosystem. Therefore, option B is correct.

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).

Location Energy production method
A burning of fossil fuels
B geothermal energy
If both the locations produce the same amount of energy, which of these statements best describes the difference between the two locations?
Location A experienced higher installation costs for energy than Location B.
Location B experienced higher installation costs for energy than Location A.
Location A uses a lesser amount of electricity than Location B.
Location B uses a lesser amount of electricity than Location A.
Answer:
Location B experienced higher installation costs for energy than Location A.
Explanation:
This is correct because with geothermal energy, it is still being experimented with, so the power plant installation will be more costly. It is also correct because the knowledge on geothermal energy is not as significant compared to fossil fuel. Because the world used to mainly use fossil fuels, we know more about it. So, the production of a geothermal plant has to be exact and will be more costly. I also got this right on my quiz.
Hope this helps!

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.
