Answer:
Biological macromolecules are organic, meaning they contain carbon. In addition, they may contain hydrogen, oxygen, nitrogen, and additional minor elements.
Explanation:
A in Bio last year.
Explanation:
Monosaccharides are simple sugar molecules so they are individual sugar molecules and Polysaccharides are a combination of several sugar molecules
If there's this picture in the question, the right answer is metaphase.
A metaphase qualifies a phase of meiosis or mitosis (following prophase and preceding anaphase) during which chromosomes, or at least kinetochores, align with the equatorial plate of the spindle. At this stage, chromosomes are at their maximum condensation and karyotypes are usually established. In the first division of meiosis, the metaphase represents the phase during which meiotic analysis is usually accomplished.
Answer:
Hydrogen.
Explanation:
Hydrogen is the simplest chemical element that exists. The symbol for the chemical element Hydrogen is "H" and it is a colourless, tasteless, odorless, and highly flammable gas.
Hydrogen is a chemical element found in group (1) of the periodic table and as such it has one (1) electrons in its outermost shell. Therefore, Hydrogen has an atomic number of one (1) and a single valence electrons because it has only one proton and one electron in its nucleus.
Based on the octet rule which states that atoms of chemical elements gain, lose or share electrons so as to have eight (8) electrons in their valence shell. Therefore, atoms of chemical elements bond in order to attain the electronic configuration of a noble gas i.e a full valence shell which comprises of eight (8) electrons.
However, the chemical element "Hydrogen" is an exception to the octet rule because it is only able to hold a maximum of two (2) valence electrons in its outermost shell to become full.
<em>Hence, Hydrogen is an element which does not want to have eight valence electrons. </em>
Answer:
The dihybrid ratio we expect in the offspring is 9:7.
Explanation:
This is an example of complementary gene interaction, which is the non allelic interaction or genes, where the prominent genes at heterozygous loci may complement each other by complementing recessive alleles at the respective loci.
So in this case of complementary gene interaction, the individuals that are A-bb or aaB- or aabb will have the same set of observable features (phenotype) but only A-B- individuals will how the dominant phenotype.
