What is herd immunity, and why are vaccines important for achieving herd immunity?

Biology
1 answer:
kap26 [50]3 years ago
8 0

Answer:

Herd immunity is a form of indirect protection from infectious disease that can occur with some diseases when a sufficient percentage of a population has become immune to an infection, whether through vaccination or previous infections, thereby reducing the likelihood of infection for individuals who lack immunity.

Explanation:

Vaccines create immunity without causing illness or resulting complications. Herd immunity makes it possible to protect the population from a disease, including those who can't be vaccinated, such as newborns or those who have compromised immune systems.

Which two generalizations can be made based on what you know about cycles of matter in a closed system?
Black_prince [1.1K]

Answer: The correct answer is option 3) The amount of matter within the system remains the same and 5) The cycle has a well-defined starting and stopping point.

A closed system can be defined as a system in which there is the only exchange of energy with the surrounding, while no exchange of matter takes place.  

In a closed system, the cycle has a well-defined starting and stopping point.

Therefore, the two generalizations which can be made for cycles of matter in a closed system are option 1) and 5)

Suresh and Gail are students in a lab working on mice with defects in the function of the HOX3A gene. In the special mouse line
Furkat [3]

Answer:

C) Both Suresh and Gail could be correct.

Explanation:

The pre-messenger RNA (pre-mRNA) transcript obtained after transcription of eukaryotic genes must undergo several processing events, including a process known as intron splicing, where introns (i.e., the non-coding sections of an RNA transcript) are removed and exons (coding regions) are joined to form a mature mRNA molecule. The three prime untranslated (3′-UTR) region of this mRNA can also bind to regulatory non-coding RNAs such as, for example, miRNAs which inhibit gene expression by inhibiting translation and/or by triggering its degradation. Moreover, the 3′-UTR region may also contain silencer sequences that bind to repressors in order to inhibit gene expression. On the other hand, translation refers to the process by which an ordered polypeptide chain (i.e., a protein) is synthesized by using the information contained in an mRNA molecule. In consequence, in the case under consideration, the mutation in the second gene could affect both RNA processing and the regulation of translation, thereby equally affecting HOX3A protein synthesis.
