Answer: A. Proteins are hydrophobic, so they shouldn’t be in an aqueous environment.
Explanation: ummm Founder Education
Membrane proteins are part of the biological membranes. Proteins are hydrophobic, and lacking in an aqueous environment was the drawback of the Davson-Danielli model. Thus, option A is correct.
What is Davson-Danielli model?
Davson-Danielli gave the membrane model, which was also called a lipoprotein sandwich model. It was proposed to show the selective nature of the membrane structure and resembles a sandwich due to its structural organization.
The lipids were layered in between the two protein layers on either side making it look like a sandwich, but the model was rejected as it didn't explain certain permeable molecules.
The arrangement was also contradictory as the proteins are hydrophobic and were placed on the outer side making them exposed to the water molecules. This constricted the movement, and the model failed.
Therefore, the hydrophobic nature of the protein failed the Davson-Danielli model.

Compare and contrast physical and chemical properties of matter.
Answer:Intensive properties, such as density and color, do not depend on the amount of the substance present. Physical properties can be measured without changing a substance's chemical identity. Chemical properties can be measured only by changing a substance's chemical identity.

Answer:
Galaxies.
Explanation:
A galaxy is a massive gravitational star system. They contain stars and their remains. Planets and other celestial bodies can orbit the stars. Between the stars is an interstellar substance containing gas, cosmic dust, and cosmic radiation, the denser regions of which are interstellar clouds. In addition, galaxies contain large amounts of dark matter, the nature of which is unknown.
Whereas for a long time the number of galaxies in the visible universe was long estimated at 200 billion, the number of galaxies is estimated to be at least 2 trillion based on recent observations.

When a germ cell undergoes meiosis, which event would MOST likely result in four aneuploid daughter
cells?
A. misalignment of the chromosomes during metaphase I
B. misalignment of the chromosomes during anaphase I
C. misalignment of the chromosomes during metaphase II
D. misalignment of the chromosomes during anaphase II
Answer:
B. misalignment of the chromosomes during anaphase I
Explanation:
Aneuploidy refers to an error in the chromosomal number of a cell. This occurs when the chromosomes fail to separate equally into individual cells, a process called MEIOTIC NONDISJUNCTION. Meiotic disjunction can occur in either the anaphase stage of meiosis I or meiosis II, however, different outcomes are produced.
When chromosomes fail to separate at meiosis I, it results in two gametes that lack that particular chromosome (n-1) and two gametes with two copies of the chromosome (n+1). This means that the four daughter cells will have an incorrect number of chromosomes, hence, the misalignment of the chromosomes during anaphase I will result in four aneuploid daughter cells.
Answer:
A. misalignment of the chromosomes during metaphase I

What is the process the does not require oxygen?
Electron Transport Chain
Fermentation
Krebs Cycle
None of the above, they all need oxygen
Answer:
The process that does not require oxygen is fermentation.
Explanation:
Fermentation is an alternative route of cellular respiration for obtaining energy, in the absence of oxygen. In aerobic respiration, oxygen is the acceptor of electrons from NADH but, in anaerobic respiration, the electron acceptor is an organic compound.
The fermentation process does not occur in the mitochondria nor does it involve the electron transport chain, and has a low energy yield at the end of the process.
With respect to the other options:
The electron transport chain and the Krebs cycle occur in the presence of oxygen.Fermentation is an alternative route for obtaining energy, in the absence of oxygen. Fermentation is the process that does not require oxygen.

The nondisjunction in the first mitosis that causes a fly gynandomorph to form could only occur in a zygote that is:_________A. XYY
B. XO
C. XY
D. XX
Answer:
A. XYY
Explanation:
Nondisjunction: The term "nondisjunction" is described as the failure of "sister chromatids" or "homologous chromosomes" to separate properly or precisely during cell division.
Gynandromorphism hasn't been discovered or identified in human beings, but it has been expressed or found in a variety of other creatures. However, a few scientists believe that gynandromorphs are considered as chimeras.
Example: In insects, the given condition can be caused due to the fact that two distinct sperm enters in one egg.

Which are two ways that plants help humans have a clean environment?
photosynthesis and cellular respiration
cellular respiration and preventing erosion
encouraging erosion and bioremediation
bioremediation and acting as a carbon sink
Answer:
The correct answer is- bioremediation and acting as a carbon sink
Explanation:
Plants play various roles in affecting the environment. Plants prevent soil erosion, pulling carbon from the atmosphere by photosynthesis incorporating or releasing oxygen by cellular respiration, acts as pollution indicator, decreases soil toxicity, provides habitat and niche and many more to balance ecosystem and improve the environment.
Plants to help in cleaning the environment can be played by these two ways:
1. bioremediation in pants or phytoremediation is the process in which the roots system of plants uses synergistic action for the growth of microorganisms and removal of toxic substances from the soil.
2. plants also play the role as a carbon sink due to the ability to absorbs a huge amount of carbon from the environment and use it to produce food and energy and releases oxygen in this process.
Answer:
bioremediation and acting as a carbon sink
Explanation:
Plants can help humans clean up pollution in the environment.
