Answer:
FALSE
Explanation:
Papillary muscles are found in the bottom chambers of the heart and attaches to the tricuspid and bicuspid valve through tendons to facilitate blood flow during systole. It also prevent prolapse. These muscles contract before the contraction of ventricular muscles (or before the contraction of ventricles) by pulling chordae tendinae till the ventricles are relaxed. This helps in preparing the valves for high ventricular pressure
Hence, the given statement is false
A diploid cell contains two complete sets of chromosomes, while a haploid cell only one set.
Answer:
The correct answer is included in the Explanation section
Explanation:
An organism with considerable more chromosomes than humans: the plant <em>Ophioglossum reticulatum</em> with 1260 chromosomes.
An organism with considerable fewer chromosomes than humans: the ant <em>Myrmecia pilosula</em> with 1 chromosome.
It might be thought that the chromosome number of a species is directly related to its complexity, meaning that an organism with a large number of chromosomes is more complex than an organism with a small number. However, this is not true. Chromosomes are structures of coiled DNA, and its number indicate how the cells wrapp their genomic material when they reproduce. The number of chromosomes is not related to the organism complexity, but rather the number of genes and their function.
Answer:
B
Explanation:
its literally a cell law .-.
The process of importing free dna from the environment is called _transformation_.
The type of dna uptake that is dependent on viruses is called _transduction_.
The type of dna uptake that is dependent on transferable plasmids is called _cconjugation_.
