Explanation:

Dolphins chasing and eating fish would be an example of a predation relationship. This is because dolphins are the predator of all such small fishes which are living simultaneously.

What do you mean by Predators?

Predators may be defined as the organisms that hunt or kill other organisms, particularly for food.

Predation is a type of interaction where one species is benefitted in the presence of another species, while the other species is harmed or lost in the presence of the first species.

Answers

Answer:

Both provide organisms with usable energy.

Explanation:

Both photosynthesis and cellular respiration, a component of the carbon cycle provides an organism with usable energy.

Photosynthesis is the process whereby green plants manufacture their food using carbon dioxide and water using sunlight to produce energy rich glucose and oxygen gas as a by-product.

During cellular respiration is an oxygen driven aerobic process in which organisms breaks down glucose to produce energy rich ATP.

Both processes furnishes an organism with energy in the end. Although, photosynthesis is an energy building process, cellular respiration breaks down materials to liberate energy. This energy is used by both plants and animals for their living activities.

Therefore, photosynthesis and cellular respiration provides an organism with usable energy.

Aquarium salt water is prepared to a salinity of 30 ppt (parts per trillion) by dissolving 3.26 kg of salt into 114 L of water. If you wanted to make 4,000 mL of salt water at the same salinity, how many grams of salt will you need?

Answers

Answer:

114 gram of salt is required.

Explanation:

Below are the following given data in the question:

Prepared salinity water = 30 ppt

Weight of salt used = 3.26 kg

The volume of water = 114 L

Below is the calculation.

4000 mL = 4000/1000 = 4L

Let the used = x kg

3.26/114 = x/4L

Now solve for the x.

x = 0.114 kg or 114 gram

Cognitive behavioral therapy (CBT) is the most widely-used therapy for anxiety disorders. Research has shown it to be effective in the treatment of panic disorder, phobias, social anxiety disorder, and generalized anxiety disorder, among many other conditions.

The treatment that is commonly used to manage stress and anxiety that are related to a disorder is meditation, which is the third option. The mediation helps the person recover from the stressful situation.

What exactly is the mental disorder?

The mental disorder is linked to the person's personal experience; for example, if the person has had any negative experiences and is unable to cope with them, the person is more likely to enter the anxiety and depression stages. These types of mental disorders can harm a person physically too, as the nervous system does not work properly, and due to this neuronal imbalance, the digestive system, sleep cycle, and cardiac health will all be affected.

Meditation can be used as a form of therapy for the individual. Because in meditation, a person is told to practice concentration on mental health by many different methods, and eventually a person gets better with time.

Consider a hypothetical scenario in which the genes that determine body color, eye color, and wing type in fruit flies occur on the same chromosome. To determine the order of the three genes on the chromosome, a researcher looks at hundreds of flies and makes these observations: 90% of flies with red eyes have curly wings. 75% of flies with red eyes have black bodies, whereas the remaining 25% have brown bodies. 1% of flies have curly wings, white eyes, and black bodies. Based on these observations, what is the most probable location of each gene on the given chromosome

Answers

Answer:

The most probable location on the chromosome of each gene is:

wing shape gene ------- eye color gene -------- body color gene

Explanation:

To know if two genes are linked, we must observe the progeny distribution. In a tri-hybrid cross, If individuals, whos genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1:1:1:1:1. If we observe a different distribution, that is that phenotypes appear in different proportions, we can assume that genes are linked in the heterozygote parent.

We can recognize the parental gametes in the descendants because their phenotypes are the most frequent, while the double recombinants are the less frequent. And simple recombinant gametes produced by the cross, which frequencies are intermediate.  

By comparing the parental and the double recombinant we will realize which is the allele that changes in position. The position of this gene is in the middle of the other two genes because in a double recombinant only the central gene changes position in the chromatid.

So, according to this knowledge and the available information in the problem we can estimate the position of the genes in the chromosome.

Phenotypic proportions:

90% of flies with red eyes have curly wings (Parental)75% of flies with red eyes have black bodies (Simple recombinant)25% of flies with red eyes have brown bodies (Simple recombinant)1% of flies have curly wings, white eyes, and black bodies (Double recombinant)

90% of individuals are red-eyed and curly-winged. This is a high frequency, which means that this is the parental phenotype. The other parental phenotype must be white eyes and straight wings.

Flies with curly wings, white eyes, and black bodies represent the lower proportion (1%) so this phenotype must be the double recombinant.

Flies with red eyes and black bodies, and flyes with red eyes and brown bodies are intermediate in proportion, so they must be simple recombinant phenotypes.

Parental)

Red, Curly  

White, Straight

Double recombinant)

White, Curly, Black  

Red, Straight, Brown  

Simple recombinant)  

Red, Black

Red, Brown

In the chromatid, there are two regions, Region 1 (from the first gene to the gene in the middle), and region 2 (from the gene in the middle to the gene of the other extreme).

The fact that both simple recombinants are red, tells us that the eye color gene and the body color gene are together, and the recombination occurred either in region 1 or 2.  

We know that the double recombinant is White, Curly, Black. We also know that the eye color gene and the body color gene are together, so one of these two must be in the middle.

Parentals are red and curly, which means that the eye color gene and wing shape gene are also together. This leads us to assume that the eye color gene is in the middle.

Finally, the fact that the double recombinant is White, Curly, Black, and knowing that the eye color is in the middle and that both the extreme alleles change position, we can assume that the parental Red, Curly is also black, while the other parental is white, straight and brown. So:

Parental)  

Curly ------ Red ------Black (90%)

Straight ----- White ----- Brown

Simple recombinant)

Curly -----White-----Brown

Straight-----Red -----Black (75%)

Curly----Red-----Brown (25%)

Straight ----White-----Black

Double recombinant)

Curly-----White------Black (1%)

Straight----Red------Brown

Feel free to edit and change things it would also be nice if you give me advice on how I can make the next few paragraphs (or anything that can help me lol) Oh and word choice is also a thing I need advice on Here is the paragraph below :3 TYSM in advance Friendship is a wonderful thing where humans interact with one another and develop a bond. It is built on trust dependence and the ability to rely on one another. There is a certain point however, where one so called friend oversteps the boundary of dependence and over relies on the other person. In this case, Lennie oversteps this boundary, becoming like a clinging parasite who cant function while alone. Lennie knows that George dose many good things for him, but he still acts out. George not only has to sacrifice a lot for Lennie he even pre plans things to do when Lennie gets himself into trouble. For starters, Lennie acknowledges the fact that George dose so much for him and still refuses to change. His hallucination even stated George is "such a nice fella an' good to you. But you dont never take no care" (Steinbeck 11). Lennie knows how well treated he is by George but he still can't control himself even for his best bud. Not only did he get himself in trouble once he did it twice. This truly shows the one-sidedness of this relationship. Additionally, His hallucination noted that "when he got a piece of a pie you always got half or more'n half" (Steinbeck 12). This shows how much George cares about Lenie and would go to lengths as even sacrificing a his own pleasure for him. I know for certain that when someone sacrifices there food for you it means that they really care for you or pity you. Even after George graciously gave many things to Lennie to give him pleasure, Lennie refuses to learn or change even though he clearly sees that George is being very kind to him. Moreover, he does all this for you and you just "stew the b'Jesus out of George all the time" (Steinbeck 16) His hallucination said. This proves that Lennie knows that he is not doing anything nice for George while Gorge is doing all these nice things for him. Lennie is intelligent enough to notice that George is supporting him and going out of his way to be kind to Lennie, while Lennie just takes and takes and takes and repays him in screwups and bad actions. As you can tell, Lennie knows that George is doing so much for him and that he is not repaying him fairly. This proves that he is not a good friend but a pericyte. Additionally, George is not only being kind to Lennie, he is sacrificing a huge chunk of his life for him. For starters, Lennies hallucination retorted, this whole time "he coulda had such a good time if it wasnt for you. He woulda took his pay an' raised **** in a ware house..." (Steinbeck 15). This shows the pleasurable life George could have had if it wasn't for the clinging weight of his parasitic so called friend Lennie. George could have had fun and lived his life worry free but he had a unnecessary responsibility witch was Lennie, that he was obligated to take care of. Additionally, Gorge even said himself that "If I was alone I could live so easy" (Steinbeck 42). This proves that George realizes what a parasitic burden Lennie is and the grim reality of the situation. This is what have could have possibly led him to killing Lennie. He finally noticed that Lennie could not change and rather than letting him suffer without him he did him a favor by ending his life. It was the last kind thing George did to Lennie. Furthermore, Lennies hallucination exclaimed that whenever there "was any ketchup, why he'd give it all to you" (Steinbeck 12). This is a perfect representation of how much George truly gives to the parasitic person he calls a friend. Lennie continuously gives his all just to get nothing- or worse than nothing- in return. Friendship is a give and take relationship that should be mutually shared between friends but in this instance we can clearly see that Lennie over stepped the boundary and takes more than what he gives. All and all, You can clearly see who is sacrificing more to maintain this toxic one sided friendship.
