True or False: Organelles are like little organs inside a cell
Answers
Answer:
True...........I hope it helps you
Organelles are like little organs inside a cell. This statement is True.
Organelles are specialized structures within eukaryotic cells that perform specific functions, much like the organs in a multicellular organism. Each organelle has a unique role in the cell's overall functioning.
For example, the nucleus contains the cell's genetic material and controls cell activities, while the mitochondria generate energy through cellular respiration.
Other organelles like the endoplasmic reticulum, Golgi apparatus, lysosomes, and chloroplasts (in plant cells) have distinct functions related to protein synthesis, packaging and transport of molecules, waste management, and photosynthesis, respectively.

Which of the following statements about meiosis is NOT true?
it occurs in sex organs
produces sex cells
results in 4 identical cells
cells produced are haploid
Answers
Explanation: Meiosis only occurs in reproductive cells, as the goal is to create haploid gametes that will be used in fertilization. Meiosis is important to, but not the same as, sexual reproduction. Meiosis is necessary for sexual reproduction to occur, as it results in the formation of gametes (sperm and eggs).
Meiosis results in 4 identical haploid cells

Explanation:
how will the offspring be affected if one of the gametes or one of the parents carry an impaired number of haploid chromosomes?
Answers
Answer :Aneuploidy often results in serious problems such as Turner syndrome, a monosomy in which females may contain all or part of an X chromosome. Monosomy for autosomes is usually lethal in humans and other animals. Klinefelter syndrome is a trisomy genetic disorder in males caused by the presence of one or more X chromosomes. The effects of trisomy are similar to those of monosomy. Down syndrome is the only autosomal trisomy in humans that has a substantial number of survivors one year after birth. Trisomy in chromosome 21 is the cause of Down syndrome; it affects 1 infant in every 800 live births
Explanation:
The meiotic division involves the formation of haploid daughter cells from the diploid parent cells. The errors during the replication can result in the uneven distribution of chromosomes, leading to aneuploidy.
Aneuploidy is defined as having a missing or extra chromosome in the genetic makeup of an organism.
Some of the problems associated with aneuploidy are:
Turner syndrome is caused due to the monosomy of the chromosomes in females. The syndrome is caused due to partial or full missing of an X chromosome. Klinefelter syndrome is also a result of aneuploidy, in which males have an extra X chromosome in their genetic make-up. Down syndrome is a condition in which trisomy occurs at the 21st chromosome of an individual.
Thus, aneuploidy is a serious condition in which the number of chromosomes is impaired leading to severe diseases.

(17 points) In which of the following circumstances would it be most likely for large organic molecules to form during a laboratory experiment?
Answers
Answer: The correct answer is : B. Laboratory experiments do not generally reflect real-life circumstances.
Explanation: One of the advantages of laboratory experiments is that cause-effect relationships are easier to consider. In a laboratory the independent variables are manipulated by the experimenters.
It is most likely that large organic molecules form during a laboratory experiment if RNA segments that could act as catalysts formed.
RNA is single-strand nucleic acid composed of a long chain of nucleotides, which can act as genetic material in viruses.Moreover, there are specific RNA molecules that also have catalytic (enzymatic) functions called ribozymes.In consequence, RNA ribozymes have dual functions since these molecules can act both as catalysts (i.e., enzymatic proteins) and genetic material (like DNA in organisms or RNA in viruses).In conclusion, it is most likely that large organic molecules form during a laboratory experiment if RNA segments that could act as catalysts formed.

The ribbon eel (Rhinomuraena quaesita), also known as the leaf-nosed moray eel or bernis eel, is a species of moray eel, the only member of the genus Rhinomuraena. What is now known as R. quaesita also includes the former R. amboinensis. R. quaesita was used for blue ribbon eels and R. amboinensis for black ribbon eels, but these are now recognized as the same species. The ribbon eel is found in lagoons and reefs in the Indo-Pacific ocean, ranging from East Africa to southern Japan, Australia and French Polynesia.[1][2] This species is widely distributed and is frequently seen by divers in Indonesian waters with their heads and anterior bodies protruding from crevices in sand and rubble habitats from very shallow to about 60 m.[3] Although generally placed in the moray eel family Muraenidae, it has several distinctive features leading some to place it in its own family, Rhinomuraenidae....[1]
