Answer:
The main pigment responsible for the yellow color of urine and the brown color of feces is called urobilin.
Explanation:
Here's how it works:
1. When red blood cells break down in the body, a molecule called bilirubin is produced. Bilirubin is a yellow pigment.
2. Bilirubin is transported to the liver, where it undergoes further processing.
3. In the liver, bilirubin is conjugated with glucuronic acid, forming a water-soluble compound called bilirubin glucuronide.
4. Bilirubin glucuronide is then secreted into the bile, a digestive fluid produced by the liver.
5. The bile flows into the small intestine, where it aids in the digestion and absorption of fats.
6. In the intestine, bilirubin glucuronide is broken down by bacteria into urobilinogen.
7. Some urobilinogen is reabsorbed into the bloodstream and eventually excreted by the kidneys, giving urine its yellow color.
8. The remaining urobilinogen is further processed by bacteria in the colon, resulting in the formation of urobilin. Urobilin gives feces its brown color.
It's important to note that factors such as hydration levels and certain medications can influence the color of urine. In some cases, a darker yellow color may indicate dehydration, while lighter or clear urine may indicate excessive hydration.
Similarly, changes in diet, certain medications, and underlying health conditions can affect the color of feces. If you notice any significant changes in the color of your urine or feces, it's always a good idea to consult a healthcare professional for further evaluation.
Answer:
a. aquatic insects
Explanation:
Aquatic insects constitute an important component of freshwater aquatic biodiversity. In addition to being very abundant in rivers and streams, they are also present in lakes and temporary water stagnations (wetlands). In water sources, these insects can live attached to stones, in decaying leaves and plant material or buried in fine sediment. Aquatic insects have different eating habits and therefore have multiple behavioral and morphological modifications.
Aquatic insects can live attached to stones, in decaying leaves and plant material or buried in fine sediment. According to the place where they live and the availability of resources, these insects have different eating habits. In this line, we have predatory aquatic insects of other insects or vertebrates such as turtles (access contents about turtles) and fish, feeding on living tissue of vascular plants and detritivorous habits that means that they feed on organic matter in suspension in the water column.
In the evolutionary history of aquatic insects, due to diversification in eating habits, they have modifications in their body appendages. In this context, we have predatory aquatic insects with raptorial legs to hold the prey, with a raptorial lip like dragonflies for the same purposes, and other detritus filters have multiple mushrooms on the anterior legs and mouth structures to retain organic matter.
According to the mode of acquisition of food, we have predators that actively forage in search of prey such as dragonflies, also passive predators such as hemiptera of the Belostomatidae family. Detritivorous aquatic insects, meanwhile, can be filters, crushers, collectors or scrapers of organic matter.

Answer:
The Population of Producers would increase
Explanation:
What’s the mRNA sequence?
What will be the amino acid sequence?
Will there likely be effects?
What kind of mutation is this?
mRNA Sequence: AUGUGGAACCGUGACU
Amino Acid Sequence: Methionine-Tryptophan-Asparagine-Arginine-Cysteine.
Likely Effects: Minimal impact, as the mutation is a silent mutation, not changing the amino acid.
Mutation Type: Point Mutation.
To find the mRNA sequence, we need to perform transcription, where DNA is used as a template to synthesize complementary mRNA. In this case, we have a substitution mutation in the DNA sequence, so the mRNA sequence will also be affected.
Original DNA Sequence: T A C A C C T T G G C G A C G A C T
Mutated DNA Sequence #5: T A C A C C T T G G G A C G A C T
The mRNA sequence is formed by replacing T with U (uracil) in the DNA sequence:
Original mRNA Sequence: A U G U G G A A C C G C U G C U G A
Now, let's determine the amino acid sequence using the mRNA sequence. Amino acids are coded by codons (three-letter sequences). Here's the mRNA sequence grouped into codons:
AUG UGG AAC CGC UGC UGA
The codons code for specific amino acids:
AUG: Methionine (start codon)
UGG: Tryptophan
AAC: Asparagine
CGC: Arginine
UGC: Cysteine
UGA: Stop codon
So, the amino acid sequence is Methionine-Tryptophan-Asparagine-Arginine-Cysteine.
As for potential effects, the mutation seems to result in a single amino acid change (from glycine to asparagine). Whether this has significant effects on the protein's function depends on its role. If the protein is critical for an essential function, even a single amino acid change can have noticeable effects. However, if it's a less crucial protein or a non-coding region, the impact may be minimal.
This mutation is a point mutation, specifically a missense mutation, where one nucleotide is substituted with another, leading to an amino acid change in the resulting protein.
