Answer:
In Aquarium C, the water level on the side with 30% solution of NaCl will be higher than the water level on the side with 5% solution.
Explanation:
The movements of molecules based on differences in concentrations of these molecules in different regions is explained by the phenomena of diffusion and osmosis.
Diffusion is the movement of moleculesmfrom regions of higher concentrationto regions of lower concentration until equilibrium concentration is attained.
Osmosis which is a special form of diffusion involving water molecules is the movement of water molecules in a solution across a semipermeable memebrane, from regions of high solvent concentration (low solute concentration) to regions low solvent concentration (high solute concentration) until equilibrium is attained.
A 30% solution of NaCl is more concentrated than a 5% solution of NaCl, therefore, water molecules will move across the semipermeable from the 5% solution to the 30% solution. This will result in a rise in the water level in the 30% solution.
Thus in Aquarium C, the water level on the side with 30% solution of NaCl will be higher than the water level on the side with 5% solution.
a plant has two alleles for color. the red allele is recessive and is represented by q. the purple allele is dominant, and represented by p. if 59 of 100 organisms are red, what is q?
A 0.48
B 0.77
C 0.23
D 0.59
Answer: B. 0.77
Explanation:
We should note that from the Hardy-Weinberg law, the formula used is:
p²+ 2pq+ q² = 1
From the information given,
p = purple allele
q = red allele
q² = 59/100 = 0.59
Then, the frequency of the red allele that is recessive will be:
q² = 0.59
q= √0.59
q = 0.768.
q = 0.77
Therefore, the correct option is B.

What additional information would you want to know to understand Emma and Jacob's panic? Include a minimum of three examples.
The correct answer to this open question is the following.
Unfortunately, you did not attach the story, the text, or the name of the article/text. Without this important information is so difficult to help you.
However, trying to help you, we did some deep search and can comment on the following.
The additional information you would want to know to understand Emma and Jacob's panic is the following.
First, you want to understand what is the real cause of the parent's panic. And all comes down to the health of their baby. The baby had problems with feeding. What happened was that Emma's baby stopped feeding after seven days.
This couple had lost a baby that died in the first nine days with no clear explanations at all. So they were traumatized by that fact and do not want to have another traumatic experience again. That is why they are afraid.
The parents desire the baby to feed normally and have the correct weight.
Parents are afraid that the baby dies or if it survives, could end up with some illness or mental ret*rdation, or could have another kind of complications when the baby is growing up.

Cows have an incredible digestive system which is highly evolved to process grass in unique ways. Please research and write a short essay regarding the function of the 4 bovine stomachs and how they all work together to process complex carbohydrates. Be sure to include the function of the reticulum, rumen, omasum, and abomasum.
Answer: Ruminants have complex digestive system.
Explanation:
Rumen: It is a sac like structure and first region of the stomach of the cow. It is connected with the esophagus. It forms the storage of the food and convert the food in the form of ball called cud.
Reticulum: It is a honeycomb like structure. It is attached with rumen. It holds and stores the heavy and dense components of the food.
Omasum: It lined with folds of tissues. It absorbs water and nutrients form the food.
Abomasum: It is called true stomach as it operate similar to non-ruminant animals. It secretes hydrochloric acid and enzymes to break down and help in feeding food.

How does the tRNA-mRNA interaction ensure that the amino acids are added in the correct order?
Answer:
Only the tRNA carrying the next amino acid in the polypeptide chain has the anticodon that binds to the appropriate location on the mRNA.
This system ensures that amino acids are added to the chain in the correct order. At the beginning of translation, the ribosome and a tRNA attach to the mRNA.

At the end of the mitotic cell cycle, a cell divides into two cells. What must happen before the cell divides? A. The number of organelles doubles. B. Chromosomes must be copied. C. Four nuclei must be formed. D. The membrane thickens.
Answer: The correct option is B.
B. Chromosomes must be copied
Explanation:
This is because, before mitosis occurs the cells must first duplicate or replicate it's DNA during interphase and this is because mitosis is a type of cell division where a parent cell divide into two daughter cells which are genetically identical to the parent cell and carry the exact number of chromosomes of the parent cell.

What might happen to a desert biome if the area received more rain than it normally receives over an extended period of time? Describe some of the changes that you might expect to see
Answer:
Desert biome will change.
Explanation:
Desert biome will change if the area received more rain than normal it receives over an long period of time because the vegetation on that area appears. The change in rainfall pattern in the desert area changes the animals present in this region because the temperature of the desert is no longer suitable for the desert animals so they migrated and other organisms come to this place.

The diagram is a heat map to show the fluctuations in temperature.
What are heat maps?A heat map is a type of data visualization that displays a phenomenon's size in two dimensions using colour. The reader will receive clear visual clues about how the occurrence is clustered or fluctuates over space from the fluctuation in colour, which may be by hue or intensity. The cluster heat map and the spatial heat map are two fundamentally distinct types of heat maps. In a cluster heat map, magnitudes are arranged into a matrix of fixed cell size, where the rows and columns represent discrete phenomena and categories. The sorting of the rows and columns is deliberate and somewhat arbitrary, with the intention of suggesting clusters or depicting them as they are identified through statistical analysis.According to the diagram, both land and sea temperatures were higher than usual.
