what is the summary equation of respiration​

Answers

Aerobic respiration takes place in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. The chemical equation is C6H12O6 + 6O2 → 6CO2 + 6H2O (glucose + oxygen -> carbon dioxide + water).

TAC GAG TTG CCG TAT ATT GCG CTC GAC TGC

Answers

Answer:

Given the sequence of DNA bases sequence:

DNA             TAC GAG TTG CCG TAT ATT GCG CTC GAC TGC

Transcription into mRNA and translation would be:

mRNA          AUG CUC AAC GGC AUA UAACGC GAG CUG ACG Amino acids Met (Start)-Leu-Asn-Gly-Ile-Stop-Arg-Glu-Leu-Thr

Explanation:

Genetic information is found in DNA, and this information depends on a sequence of bases —adenine, thymine, cytosine and guanine— in the DNA molecule.

Transcription consists of creating a strand of mRNA, from the sequence of bases in a DNA strand, which it assumes:

The sequence of RNA is complementary to the DNA sequence that forms it, following the complementarity of bases. In RNA there is no base thymine, which is replaced by uracil.

The sequence of mRNA is organized into triplets or codons, each of which encodes for the synthesis of an amino acid (translation), indicating both the start of a polypeptide chain and the stop of protein synthesis.  Knowing this information, it can be stated that, following a sequence of DNA bases, the resulting transcription and translation would be:

DNA                TAC GAG TTG CCG TAT ATT GCG CTC GAC TGC Transcription AUG CUC AAC GGC AUA UAACGC GAG CUG ACG Translation    Met (Start)-Leu-Asn-Gly-Ile-Stop-Arg-Glu-Leu-Thr

Answers

Answer:Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel. These primary producers form the base of an ecosystem and fuel the next trophic levels.

g If you look carefully at this organism, you will not see any organs for gathering oxygen or releasing carbon dioxide or ammonia. There is no circulatory system. How does this animal perform these functions

Answers

Answer:

Simple unicellular organisms like Amoeba and some multicellular organisms like Hydra use their cell surface and skin for gaseous exchange with their environment.

Note: The organism in the question was not stated.

Explanation:

The complexity of an animal determines its metabolic needs, and hence, its requirement for specialized structures and functions.

Simple unicellular organisms are able to meet their metabolic needs such as gaseous exchange by simple diffusion through their cell surfaces. Such organisms include amoeba, paramecium, etc.

Some multicellular organisms lack specialized organs for nutrient transport and gaseous exchange such as hearts and blood vessels, etc. Example of such organisms are Hydra and Planaria. They have their cell surfaces in contact with the external environment, and thus use their skin for gaseous exchange by means of diffusion.

Based on the internal and external solute concentrations, do you think the paramecium will swell up or shrink in this solution? Explain your reasoning.

Answers

Answer:

Depending on the external and internal solute concentrations, the paramecium will either, shrink, remain the same size or swell.

If the external solute concentration is less than internal solute concentration, the paramecium will swell.

If the external solute concentration is equal to the internal solute concentration, the paramecium will remain the same in size.

If the external solute concentration is greater than the internal solute concentration, the paramecium will shrink.

Note: The concentrations of the external and internal environments were not given.

Explanation:

When two compartments containing solutions are separated by a semipermeable membrane, by means of osmosis, water can move in or out of a compartment depending on the concentration of solutes in either compartments.

In a cell such as a paramecium, the cell membrane serves as a semipermeable membrane.

If the concentration of solutes in both the internal and external environment are the same, there is no net movement of water molecules, and the solutions are said to be isotonic.

If the concentration of solutes in the external environment is greater than the internal environment, water molecules moves out from the internal to external environment, and the paramecium shrinks in size.

If the concentration of solutes in the external environment is less than the internal environment, water molecules moves from the external into the internal environment, and the paramecium swells up in size.

Explanation:

Ubiquitous means present or found everywhere. Microbes, are the most abundant organisms on Earth, also called microorganisms. There are several types of microbes, usually classed as protists, protozoa, algae, bacteria, viruses, and fungi.

As integral parts of our ecosystems, they are essential in their roles as producers, consumers, and decomposers and are capable of inhabiting a wide range of climates and niches- from the hottest volcanoes, icy tundras to the deepest regions of the ocean. Microbes are also essential to macro-organisms; in humans, they aid in the digestion of food and maintain gut health. Additionally, microbes can be used in the production of food, medicine, fuel, and other biotechnological applications.

Nucleic Acids:

Explanation:
Since we only have one strand shown, I'm going to assume it is RNA. Both DNA and RNA have nucleic acids, but RNA has 1 different nucleic acid; it replaces Thymine with Uracil. So the 4 nucleic acids are uracil, adenine, guanine, and cytosine.
If the picture shown is a cross-section of DNA, then our 4 nucleic acids are adenine, thymine, guanine, and cytosine.

What is one way that calcitonin and parathyroid hormone maintain homeostasis?

A. Calcitonin stimulates the kidneys to excrete calcium when calcium levels are too high, while parathyroid hormone stimulates the kidneys to absorb calcium when calcium levels are too low.
B. Calcitonin stimulates the bones to excrete calcium when calcium levels are too high, while parathyroid hormone stimulates the bones to absorb calcium when calcium levels are too low.
C. Calcitonin stimulates the kidneys to absorb calcium when calcium levels are too low, while parathyroid hormone stimulates the kidneys to excrete calcium when calcium levels are too high.
D. Calcitonin stimulates the bones to absorb calcium when calcium levels are too low, while parathyroid hormone stimulates the bones to excrete calcium when calcium levels are too high.

Answers

Answer:

The way calcitonin and parathyroid hormone maintain homeostasis in the body is calcitonin stimulates the kidneys to excrete calcium when calcium levels are too high, while parathyroid hormone stimulates the kidneys to absorb calcium when calcium levels are too low (option A).

Explanation:

Calcitonin and parathyroid hormone have a role in maintaining the balance of calcium and phosphorus concentrations, but their effects are opposite.

The reduction of calcium levels promoted by calcitonin is based on:

Inhibition of intestinal absorption of calcium and bone resorption or decalcification. Increases the excretion of Calcium by the kidneys.

On the other hand, parathyroid hormone increases calcium levels by performing the opposite effect of calcitonin:

It stimulates intestinal absorption and bone resorption. It increases renal calcium reabsorption.

Both mechanisms contribute to maintain the levels of calcium, when it is high or low in the organism, collaborating with the maintenance of the homeostasis.

The other options are not acceptable because they do not describe the correct function of calcitonin and parathyroid hormone.
