Answer:
Amino acids are organic compounds that contain amino and carboxylate functional groups, along with a side chain specific to each amino acid.
Explanation:
Amino acids are small molecules that are the building blocks of proteins. Chemically, an amino acid is a molecule that has a carboxylic acid group and an amine group that are each attached to a carbon atom called the α carbon.
The frogs genetic variation of their offspring is incredible.
<h3>Life cycle of frogs:</h3>
The process begins when adult frogs deposit hundreds of small eggs, known as frogspawn, that collect together in clusters. Early in the spring, as the temperature is just beginning to warm up, this occurs.
Tadpoles won't move around much for the first week or two after hatching since they are still taking nutrition from the yolk of their egg. But once the yolk is completely consumed, the tadpoles are large and robust enough to enter their aquatic environment.
Frogs and toads depend on water significantly less as adults. They can live on land as long as they stay in the shade and don't dry up, but they frequently go back to ponds and lakes for a splash.

Answer:
holds a reserve supply of oxygen in muscle cells.
Explanation:
Myoglobin is an iron-containing protein whic is found in the muscle cells. It is similar to hemoglobin with respect to its structure. The main function of myoglobin is to store oxygen in the muscle cells that is need for muscles functioning. Myoglobin r<u>eceives oxygen from the red blood cells and transports it to the mitochondria of muscle cells, where the oxygen is used in cellular respiration to produce energy.</u> The organism can utilize the oxygen in its lungs for a much longer period of time if the concentration of myoglobin becomes high in the muscle cells,
Answer:
Yes
Explanation:
At room temperature, exposed elemental mercury can evaporate to become an invisible, odorless toxic vapor. ... Elemental mercury is an element that has not reacted with another substance.
The green organisms collected from the pond by Ricardo may be plants or protists. It is required to key out these organisms so that they can be differentiated. In order to determine whether or not these organisms are plants, he should check for the key features of plants, such as whether or not the organisms do photosynthesis. and whether these organisms are multi-cellular or unicellular.
The protists may also contain chloroplasts and cell wall made up of cellulose. Therefore, testing for the presence of these features will not help in determining whether the collected organisms are plants or not.
Hence, he should check whether the organisms are capable of doing photosynthesis or not.
