Which of the following statements about the nucleus is not true?
a. the nucleus stores the coded instructions for making the cell’s proteins.
b. the nucleus usually contains a nucleolus region which is where ribosome assembly begins.
c. the nucleus is the site of protein assembly.
d. the nucleus is surrounded by a nuclear envelope that lets materials in and out.

answer;

the nucleus is the cite of protein assembly

explanation;

-the nucleus is an organelle found in eukaryotic cells. inside its fully-enclosed nuclear membrane, it contains the majority of the cell's genetic material. this material is organized as dna molecules, along with a variety of proteins, to form chromosomes. it governs gene expression and facilitates dna replication during the cell cycle.

-it coordinates the cell's activities, which include growth, intermediary metabolism, protein synthesis, and reproduction (cell division).

-protein assembly takes place in the cytoplasm in the structures called ribosomes found out-side the nucleus.

false because ozone (o3) depletion does not cause global warming, but both of these environmental problems have a common cause: human activities that release pollutants into the atmosphere altering it.

global warming is caused primarily by putting too much carbon dioxide into the atmosphere when coal, oil, and natural gas are burned to generate electricity or to run our cars.

explanation:

picture a world where computers are building made-to-order personalized robotic arms and synthetic organs, drones are circulating above mars! due to the rapid growth of technology, the future has never been more unpredictable, and it presents a huge challenge in education: we are teaching students how to work in a future that we have never been unsure of. it is widely predicted that in eight years’ time, there will be more jobs in the fields of science, mathematics, technology and engineering than in any other discipline. and, as the technology continues to develop, it will soon become clear that addressing social problems will involve more innovative thinking, and analytical and technical knowledge than ever before. undeniably, there are no subjects that encourage innovative and creative thinking, deep thought, problem solving and independence more than the stem subjects. while it is widely commented on that there is a need to reimagine the ways stem subjects are taught in schools by embracing a more interactive and innovative approach to appeal to more students, it should come as no surprise that some of the most reputable educational organizations in the world are already implementing changes to embrace stem. harvard, for example, announced in 2014 that they were increasing their computer science faculty by over 50% and has since introduced computer science as a core subject for all freshmen. the urgency of supporting stem subjects at a young age is becoming more relevant than ever, as adopting a keen interest in the curricula needs to happen early. however, beyond the age issue is one of gender.
