the answer is Mid brain
The optic nerve of each eye meets the other at the optic chiasm. Medial nerves of each optic nerve cross, but lateral nerves stay on the same side. The overlap of nerve fibers allows for depth perception. Electrical impulses are communicated to the visual cortex of the brain by way of the optic nerve.
RNA or Ribonucleic acid is a molecule similar to DNA. It is single-stranded, has nitrogenous base pairs, and a sugar molecule. The RNA can be categorized into mRNA, tRNA, and rRNA.
The correct sequence of nucleotides in the tRNA will be:
U - U - A
In the nucleotide sequencing, the nitrogenous compounds present in the RNA are adenine, guanine, cytosine, and uracil instead of thymine.
The mRNA is a single messenger molecule, which is made from the transcription of DNA molecule. The further process involves the translation in which ribosomes play a crucial role.
In translation, the polypeptide is synthesized by the information delivered by the mRNA. The information in the mRNA is read in the form of a group of three nucleotides, known as a codon.
The codon is then read by the corresponding anticodon region of the tRNA molecule. It makes the set of the anticodon, which is complementary to the codon.
For instance, the mRNA containing the base pairing of A-A-U, the complementary sequence made by tRNA will be U - U - A.
Therefore, the correct answer is U - U - A.
To know more about mRNA and tRNA, refer to the following link:
Answer:
U-U-A
Explanation:
A mRNA molecule is formed as a result of transcription, which then proceeds to the ribosomes in the cytoplasm to undergo translation. Translation is the process whereby an amino acid sequence (protein) is synthesized using the information in the mRNA molecule/sequence. The mRNA sequence is read in a group of three nucleotide bases called CODON. Each codon specifies an amino acid.
This codon is read by another RNA molecule in the ribosome called tRNA (transfer RNA). tRNA contains another set of three nucleotides called ANTICODON, which is complementary to the CODON and responsible for reading the codon in order to carry the corresponding amino acid to the growing sequence.
According to this question, a portion of a messenger RNA molecule contains the base sequence A-A-U, the complementary anticodon sequence of the tRNA would be U-U-A.
Answer: The biosafety level required for a microbiology laboratory working with potentially airborne pathogens such as tuberculosis bacteria is Biosafety Level 3 (BSL-3).
Explanation:
BSL-3 laboratories are designed to handle microorganisms that can cause serious or potentially lethal infections through inhalation. Here are some key features and practices typically found in BSL-3 laboratories:
1. Facility design: BSL-3 laboratories have specialized engineering controls to prevent the release of airborne pathogens. These controls include directional airflow systems that ensure air flows from clean areas to potentially contaminated areas, preventing the escape of pathogens into the environment.
2. Personal protective equipment (PPE): Personnel working in BSL-3 labs must wear appropriate PPE, including respiratory protection such as N95 masks or powered air-purifying respirators (PAPRs) to prevent inhalation of infectious aerosols.
3. Containment equipment: BSL-3 labs have specialized containment equipment, such as biological safety cabinets (BSCs), that provide an additional physical barrier between the personnel and the infectious agents. BSCs use high-efficiency particulate air (HEPA) filters to trap and remove infectious particles from the air.
4. Training and protocols: Personnel working in BSL-3 labs receive extensive training on handling potentially infectious materials and following strict protocols to minimize the risk of exposure. This includes proper decontamination procedures, waste disposal, and disinfection practices.
5. Access control: Access to BSL-3 laboratories is restricted to authorized personnel who have undergone appropriate training and are familiar with the specific safety requirements.
In summary, a BSL-3 biosafety level is required for microbiology laboratories working with potentially airborne pathogens like tuberculosis bacteria. These laboratories have specialized infrastructure, equipment, and protocols in place to protect personnel and prevent the release of infectious agents into the environment.
Answer:
All of the following statements about culture are true except for "a. it is not transmitted across generations."
Culture refers to the shared beliefs, values, customs, behaviors, and artifacts that characterize a particular group or society. It is an essential part of human societies and influences various aspects of our lives. Here are the correct statements about culture:
b. Culture provides a blueprint that determines the way we think, feel, and behave in society. It shapes our worldview, influences our perceptions, and guides our actions. For example, cultural norms and values influence how we interact with others, make decisions, and interpret social situations.
c. Culture helps to define who we are. Our cultural background plays a significant role in shaping our identity. It contributes to our sense of belonging, shapes our individual and collective identities, and influences how we perceive ourselves and others.
d. Culture influences our knowledge, beliefs, and values. It provides a framework for understanding the world around us and shapes our understanding of what is right, wrong, important, or valuable. For instance, cultural beliefs may influence our attitudes towards education, religion, family, gender roles, and social issues.
However, statement a. is incorrect. Culture is indeed transmitted across generations. It is passed down from one generation to another through various mechanisms such as socialization, education, storytelling, traditions, and language. Each new generation learns and internalizes the cultural practices and beliefs of their society, contributing to the continuity and preservation of culture over time.
In summary, culture is transmitted across generations and has a profound impact on our thoughts, feelings, behaviors, identity, and values.
