N a garden with trees and shrubs, green and pink katydids were observed. Over time, birds started feeding on the katydids. Which two statements describe what will eventually happen to the population of the katydids?
Answer: A.The population of pink katydids will decrease.
B.The population of green katydids will decrease.
Explanation:
The two statements describe what will eventually happen to the population of the katydids are that:
• A.The population of pink katydids will decrease.
• The population of green katydids will decrease.
This is because from the information given, since birds started feeding on the katydids, this will result in the reduction in the number of katydids. Hence, the decrease in both the pink and the green katydids.
Answer: A: The population of pink katydids will decrease.
C: The population of green katydids will increase.
Explanation: The birds that feed on the Katydids will see the pink ones due to the green ones being camoflauged. The pink katydids will decrease and the green katydids will increase.

¿Cuál es la molalidad de una disolución al mezclar 4 kg de agua como disolvente con 0,5 Mol de ácido clorhídrico (HCl) como soluto?
Answer:
La molalidad de la disolución es 0,125 molal.
Explanation:
En la teoría de las disoluciones químicas, la molalidad se define como la cantidad de moles del soluto dividida por la masa de solvente, entonces tenemos que la molalidad de la disolución descrita en el enunciado es:
[tex]m = \frac{0,5\,mol}{4\,kg}[/tex]
[tex]m = 0,125\,m[/tex]
La molalidad de la disolución es 0,125 molal.

the renal arteries: renal arteries are the route of blood
Explanation:
renal arteries are the route by which blood enters the kidney
Answer:
Blood flows into your kidney through the renal artery.
Explanation:
This large blood vessel branches into smaller and smaller blood vessels until the blood reaches the nephrons. In the nephron, your blood is filtered by the tiny blood vessels of the glomeruli and then flows out of your kidney through the renal vein.
The water cycle is a closed system, meaning no water enters from beyond the system nor leaves the
system. What does that say about the importance of keeping water on Earth free from pollution?
Answer:
there are no possible changes adaptations
Explanation:
what i mean by that is if a substantial amount of pollution enters the water cycle its going to be nearly impossible for it to get out
If water present on earth is polluted anywhere in the cycle, it starts affecting the system of water and percolation as well as plants become limited that what they will do in order to clean the water. It is possible that if ground is polluted than water will also get polluted. It means that the water present on earth is same the water present from the beginning and will continue to be the same water that is available.
What is groundwater?Groundwater has been defined as water present in the underground water below the soil as well as in the cracks of the earth. The percentage of freshwater in the world would be 30%. There are mainly three types of groundwater and these are hand-dug wells, as well assprings, and drilled boreholes.
The water stored under the ground has obtained from the rain and stored in the ground so that it can be used later. Ground water has very clean and fit for drinking and the reason could be the soil present on top and work as filter and the groundwater is free from all microorganisms.
Therefore, If water present on earth is polluted anywhere in the cycle, it starts affecting the system of water and percolation as well as plants become limited that what they will do in order to clean the water. It is possible that if ground is polluted than water will also get polluted. It means that the water present on earth is same the water present from the beginning and will continue to be the same water that is available.

It is impossible for sperm to be functional (able to fertilize the egg) until after ________. Group of answer choices
Answer:
The answer is "they undergo capacitation"
Explanation:
Sperm migrate through uterine contractions and the energies of its flagella to the uterine tube. In sperm motility, reverse peristalsis is engaged in the uterus and uterine tubes. For a sperm cell to fertilize an egg, it takes approximately 24 hours. The surface of the egg changes as the sperm penetrates the egg, therefore no sperm is allowed within. The kid is fully genetic, including whether it's a boy or a girl at the time of fertilization. Until they are trained it is difficult for sperm to be working.

does the presence of introns exons in eukaroytic cells provide more potentia diversity in gene products than is possible in porkatroi cells
Answer: Yes. Splicing can be done in different ways to yield different mRNAs wich will create different proteins. Prokaryotes are not able to do this.
Explanation:
DNA (deoxyribonucleic acid) is a molecule that contains the genetic information for synthesizing amino acids that form proteins. To do this, DNA must first be transcribed into RNA (ribonucleic acid) and this is the molecule used for protein synthesis (translation). The newly transcribed RNA (called primary messenger RNA) from DNA results in a very long molecule and also has regions that do not code for anything, called introns, which are removed by a process called splicing. Exons are segments in the RNA that do code for amino acids and remain in the mature mRNA after splicing.
Splicing is a process by which introns are cleaved from the primary messenger RNA and exons are joined to generate mature messenger RNA. In addition, alternative splicing occurs which allows different mRNA isoforms and thus different proteins to be obtained from a primary mRNA transcript. This is because the exons will be joined or spliced in different ways, giving rise to different mature messenger RNA sequences. This process occurs mainly in eukaryotes, although it can also be observed in viruses. But it does not take place in Prokaryotes (Bacteria).
In summary, exons/introns can be spliced together in different ways to yield different mRNAs sequences. Each different mRNA sequence will code for a different protein.

As you move up an energy pyramid, all of the following decreases except for
the biomass for the trophic level
the energy at each trophic level
the number of organisms in each trophic level
the average percentage of energy lost as heat
Answer:
the average percentage of energy lost as heat
Explanation:
An energy pyramid (also called trophic pyramid) is a graphical representation that exhibits how energy flows at each trophic level in a particular ecosystem. In an energy pyramid, it is possible to determine how much energy is available at each trophic level and how energy flows from producers (e.g., photosynthetic plants) to primary consumers (e.g., herbivores), then from primary consumers to the next trophic level (e.g., carnivores), and so successively to all major trophic groups (e.g., higher carnivores). During this chain, energy is lost as heat when it is transferred to the next level, and the average percentage of energy lost increases at each trophic level, thereby less and less energy is available to major trophic groups.

Which of the following statements describes the conditions of a pneumothorax? View Available Hint(s) Which of the following statements describes the conditions of a pneumothorax? The intrapulmonary pressure equalizes to atmospheric pressure. Both lungs partially or completely collapse. The intrapleural pressure decreases. The presence of air in the pleural cavity.
Answer:
The presence of air in the pleural cavity
Explanation:
A pneumothorax occurs when air builds up between the lung and the chest wall. In consequence, pneumothorax occurs when air gets into the pleural cavity (i.e., the space between the lung and the chest wall) and causes a fully and/or partially collapsed lung. Some of the most common symptoms of pneumothorax include shortness of breath (respiratory distress), rapid breathing, rapid heart rate, fatigue, agitation, dry cough, etc. Pneumothorax can be caused by a chest injury, an accident during a medical procedure, damage from underlying lung diseases, etc.

help me ..it's a MCQ
Explanation:
I think your answer is D, and let me explain why.
Heat can denature proteins quickly because proteins have very specific temperatures at which they act best. If the temperature rises too high/falls too low with respect to that threshold, then that will cause the proteins to stop working properly and eventually die.
pH is also very important with how proteins work, and it's the same reason as heat. Proteins have a certain range of pH's that keep them healthy and working, but as soon as the pH changes dramatically outside of that range, the proteins will be quickly denatured.
And lastly, organic solvents can denature proteins as well (e.g. alcohol), which makes sense because they are solvents (a solvent is something that dissolves other substances). I'm not sure about the exact chemistry / biological responses behind it, but it's what would be expected of a solvent.
With all of this in mind, I think your answer should be D!
