Amino acids. These class of compounds
are considered the building blocks of most organisms, and around 500 of these
are known and indentified. All proteins, carbohydrates, and nucleic acids are
polymers ("many units") and each unit is an amino acid.
A is correct. DNA replication is just a different way of saying Meiosis II.
Answer:
Well, on one hand, this is a good thing as negative effects of the high demand for wood such as deforestation can be minimised. This will also sustain the supply of wood for several applications. However, there could be negative consequences of propagating such genetically-modified trees, which were not stated or are not yet known. For instance, the trees could be extreme soil nutrient consumers—depleting soil nutrients at a faster rate than they can be replenished and rendering such soil infertile in a short period.
Answer:
the body has glucagon and insulin, glucagon tells the body to release more glucose whenever glucose levels are low and insulin feels the glucose to the body, reducing glucose levels
Explanation: pretty much it
If the shape of radish is under the control of one gene, for example A than we can say:
AA is dominant homozygous genotype-round radish phenotype,
aa is recessive homozygous genotype-long radish phenotype
If we cross round and long radish:
P: AA x aa
F1: Aa Aa Aa Aa
Aa is heterozygous genotype-oval phenotype
If we than cross the F1:
Aa x Aa
F2: AA Aa Aa aa
This means that the ratio between the phenotypes woul be 1:2:1 (round:oval:long).
