Answer:

1. 10% of the energy at lower trophic level

2. Methylmercury biomagnifies in an ecosystem, meaning its concentration increases  as it moves through each higher trophic level

3. Scientists can measure oxygen used during a plant’s cellular respiration by measuring dissolved oxygen in water

4. Energy transfer is inefficient between trophic levels because 90% energy is retained at each trophic level

5. Primary productivity is defined as rate at which energy is transformed into organic matter.

Explanation:

1. The energy transferred from lower tropic level to its next trophic level is equal to 10% of the total energy at the lower level.

2. increases

3. By measuring dissolved oxygen in water after every 24 hours. Reduced DO  value from the prior reading indicate the amount of oxygen used by plants

4. Because nearly 90% of energy is retained at each trophic level to carry out cellular metabolic activities.

5. It is the rate at which energy is transformed into organic matter.

Provide explanations of genotypes and phenotypes.
Korvikt [17]
The phenotype is the physical appearance of an organism, while the Genotype is the genetic composition of an organism. Phenotype is observable and are the expression of the genes of an individual. So even the organism with the same species may differ, with a minute difference in their genotype. This is the main difference between the two.

We can notice one’s hair colour, eye colour, height, weight, skin colour, etc. but cannot look at genes responsible for these characters, so the observable physical look is the phenotype while the unnoticed genes responsible for such characters present in the DNA of cell of the individual is genotype.

To explain the above lines, here is the simple example of a pure red colour flowering plant (RR) is crossed with the white colour flowering plant (rr). The result of the Genotype of the F1 generation will be – Rr (Hybrid red colour), and the Phenotype of the F1 generation will be the – Red colour flowering plant.

Genotype and phenotype are the two very closely related and similar-sounding words, but their meaning is different. Our earth has a dynamic variety of organisms, present in soil, water and on land. But as the genome of each organism is different, and so there phenotypes also whether it’s their colour, height, weight or other morphological features.

Which portions of the large intestine are located in the pelvic cavity?
Whitepunk [10]

The sigmoid colon, which begins in front of the pelvic brim, is a section of the large intestine that is located in the pelvic cavity.

The sigmoid colon typically measures 25 to 40 cm in length (10 to 15.75 in). As a continuation of the descending colon, the sigmoid colon is a "S"-shaped section of the large intestine that starts in front of the pelvic brim and changes into the rectum at the level of the third sacral vertebrae.

<h3>The large intestine is it located in the pelvic cavity?</h3>

The urine bladder, the remainder of the large intestine (the bottom region), and the internal reproductive organs are all located in the pelvic cavity, which is the lower part.

<h3>Which digestive system organ is located in the pelvis?</h3>

The inferior portions of various abdominal viscera are located in the larger pelvis (terminal ileum, cecum, sigmoid colon).

<h3>Where in the abdominal cavity is the big intestine?</h3>

From the ileocecal junction to the anus, the large intestine continues the ileum for 1 to 1.5 meters. The majority of the large intestine is found in the abdominal cavity, and the remaining part is found in the pelvic cavity.
