The birth and reproduction of Carrier(Heterozygous) organisms, (i.e) heterozygous individuals that have a dominant allele masking the effects of the recessive 'lethal gene.' However even though the gene is masked, it is still there. Therefore, if the heterozygous individual is to reproduce with another heterozygous (carrier) organism there is a higher chance that their offspring will have the active form of the 'lethal gene' causing the death of the offspring.
Answer:
A: haploid, each containing 23 chromosomes
Explanation:
Answer: It is because it makes it more efficient to study organisms.
Explanation: Biologist classify organisms by considering similarities between them. The organisms which have closely related characteristics are placed in a separate domains by biologists. Domains are further divided into 6 Kingdoms. According to modern classification system, domain is largest unit of biological classification.
Answer:
A typical atom consists of three subatomic particles: protons, neutrons, and electrons (as seen in the helium atom below). Other particles exist as well, such as alpha and beta particles (which are discussed below). The Bohr model shows the three basic subatomic particles in a simple manner. Most of an atom's mass is in the nucleus—a small, dense area at the center of every atom, composed of nucleons. Nucleons include protons and neutrons. All the positive charge of an atom is contained in the nucleus, and originates from the protons. Neutrons are neutrally-charged. Electrons, which are negatively-charged, are located outside of the nucleus.
Answer:
secondary structure ... hydrogen bonds...
Explanation: Some regions of a polypeptide may coil or fold back on themselves. This is called secondary structure, and the coils or folds are held in place by hydrogen bonds.
