Answer:
Carbohydrates are organic molecules ONLY composed of carbon, hydrogen, and oxygen molecules. So, their structure would be just covalent bonds between the three elements, and most likely non-polar. They give out a lot of energy, and carbohydrates are also known as sugars. Most foods have them.
Branliest plzzzz?
The correct answer is A.
The official guidelines from doctors state that infants should start consuming solid food after the age of six months. In order for the infants to be safe and healthy, they need to be able to sit up, support their back and chew safely before being given solid food.
Answer:
When we talk about the inheritance of traits, or the passage of traits from parents to future generations down the line, we are not just talking about the visual (phenotypical) expression of those traits, but also, their underlying explanation, which is the genotype. A genotype is basically how the genes of the parents combine in such a way that the children inherit a set of traits from the parents, and express them phenotypically, or not.
In the case of blood types, we have four phenotypic groups: A, B and O. Each one of these types is characterized by the underlying set of genes that are responsible for what is expressed. While the O blood type presents a genotype ii, which is recessive, the A and B types will have the following genetic patterns: Ia Ia, or, Ia i (characteristic of the O genetic material) for the A type and: Ib Ib, or Ib i, for the B type. When there is a genetic conjugation from parents genetic material, regarding blood type, we would have these sets of genes combining. In most of the possible combinations genetically speaking, we have the recessive i gene appearing, including in the A and B dominant blood types. This means that when crossed, there will always be a chance of at least one offspring presenting the O blood type, even if one of the parents is dominant A, or B.
In answer: it is the fact that all three types present the recessive allele i, typical of the O blood type, that when pairings of genes happen between parents, the genetic characteristic of the O type may present itself in a dominant fashion, instead of the usual recessive pattern.
