A frog heart has 3 chambers, 1 ventricle and 2 atria. One atrium (the right) receives deoxygenated blood from the frog's body (in the systemic circulation) and then pumped to the single ventricle wherein it will go to the lungs to be oxygenated. Another atrium (the left) received oxygenated blood from the lungs then pumped to the single ventricle wherein it will go to the systemic circulation. In the single ventricle, some form of mixing of the oxygenated and deoxygenated blood happens but since the frog is a cold blooded animal, the decrease in the concentration of oxygen is deemed superficial.
This advancement allows the frog to live on land using the lungs as the primary organ for oxygenation of the blood.
Answer:
cells are living, atoms are not.
Explanation:
Atoms are the building blocks of everything, not just life as cells are.
Answer:
Allele is the form in which sequenced information within a single gene can be expressed. One allele is paired with another within a gene, which is part of a chromosome and which determines the expression of specific traits.
Explanation:
The genetic information is contained in the DNA, and each molecule of this nucleic acid forms a chromosome containing genes, fragments of the DNA of the chromosome with a sequence of nucleotides for the synthesis of specific proteins.
Genes determine morphological or functional features of a living being. Each gene contains two alleles for each trait it determines, the alleles being different sequences of nucleotides that constitute different ways in which a trait can be expressed.
<h3>How are the alleles related to genes, chromosomes and traits?
</h3>
Each gene contains two alleles, either the same or different, with the sequence of nitrogenous bases to determine the possible ways in which a trait is expressed. The different sequences of the alleles can produce specific modifications of the function of that gene, conditioning the different forms of expression of a trait.
Genes, which contain alleles, are found within a chromosome, at a specific location called a locus.
Answer:
Diabetes is a condition in which your blood glucose, often known as blood sugar, is abnormally high. Your main source of energy is blood glucose, which comes from the food you eat. Insulin, a hormone produced by the pancreas, aids glucose absorption into cells for use as energy.
