Active and passive humoral immunity are both mechanisms of adaptive immunity that use antibodies. yes this is true
- Our adaptive immune system protects us from infection-related mortality. An new-born born with a significantly compromised adaptive immune system may die shortly unless extreme steps are taken to isolate it from a wide range of infectious agents such as bacteria, viruses, fungi, and parasites.
- The purpose of adaptive immunity is to eliminate invading infections as well as any harmful chemicals they create. Because these reactions are damaging, it is critical that they only occur in response to molecules that are alien to the host and not to molecules that are native to the host. The adaptive immune system's capacity to identify what is foreign from what is self is a fundamental feature.

Explanation:
Compare and contrast a frameshift mutation and a single nucleotide substitution mutation in a DNA sequence encoding a protein. How many nucleotides would be inserted or deleted in each? How many amino acids in the protein sequence would be altered in each?
Answer:
The correct answer will be- phloem transports photsynthetic products to the roots
Explanation:
Phloem is the vascular tissue which specializes in transporting the solute molecules like sugar in the form of sucrose to in the plants.
The phloem connects the photosynthetic organ (Leaves) to non-photosynthetic organs (stem and roots) of the plants by transporting the photosynthates or sucrose to various parts.
Since the roots also need the energy to perform metabolic functions so need the photosynthates to synthesize the energy molecule. They receive the photosynthates from the phloem.
Thus, phloem transports photosynthetic products to the roots is the correct answer.
Answer:
developmental toxicity. im not sure though,
Explanation:
if im wrong im sorry
Answer:
As the human population has grown, the need for more land has caused an increase in the cutting down of forest lands for habitation and farming. The result has been an increase in soil erosion, an increase in species extinction from habitat loss, and a reduction of oxygen supplied by the trees, as well as lower amounts of carbon dioxide being removed from the atmosphere. Industrial and personal use of fossil fuels has dramatically increased the amount of air pollution in the atmosphere while systematically using up the supply of the non-renewable resources such as coal, oil and natural gas
