It occurs in Meiosis
blsea [12.9K]3 years ago

Answer:

miosis

Explanation:

Does crossing over occur in metosis? No, because chromosomes do not pair up (synapsis), there is no chance for crossing over. Following cytokinesis what chromosomes do the daughter cells contain? Daughter cells contain the same number and kind of chromosomes that were in the original cell.

The independent variable is what will change. The dependent variable is what will change because of the independent variable. The controlled variable is what will stay the same.
Ex, for the first one.
IV: the amount of sunlight
DV: plant growth
CV: pea plant

For #2.
IV: the soda
DV: the amount of sugar
CV: soda

And so on

The following are the reasons fats are essential for the body;

  • They provide energy for the body too.
  • Fats are good insulators helping to keep the body warm.
  • They help the body absorb vitamins because some vitamins are only soluble in fats.
  • They help in growing of the cell.

How could the notion of maximum parsimony lead to an error in establishing an evolutionary relationship
Grace [21]

Answer:

The notion of maximum parsimony does not consider the entire evolutionary history, being able to suppress important evolutionary points that would cause errors in the evolutionary relationship of a species.

Explanation:

Maximum parsimony is a criterion for optimizing phylogenetic trees. This is because through this criterion an analysis is made of all possible phylogenetic trees of a species, observing which one is smaller and offers simpler and summary information. On the one hand, the study of the smallest phylogenetic tree can be faster and more understandable, since its information is basic and direct. However, maximum parsimony can lead to errors in the establishment of an evolutionary relationship of a species, because it suppresses the entire history of evolution of that species, being able to suppress really important points in one of the clades, which would result in an incorrect evolutionary conclusion.

Toward an Artificial Cell Scientists have recently constructed an artificial ribosome in vitro from purified ribosomal proteins
dalvyx [7]

Answer:

RNAs and proteins can bind via electrostatic interactions, hydrophobic interactions, Hydrogen bonding interactions and base stacking interactions

Explanation:

Proteins bind to nucleic acids (i.e., both DNA and RNA) through different types of interactions:

- electrostatic interactions, also known as van der Waals interactions, refer to attractive/repulsive interactions between molecules depending on their electric charges.

- hydrophobic interactions, i.e., interactions between nonpolar molecules and water molecules

- Hydrogen bonding interactions resulting from the interaction between a hydrogen (H) atom that bind to an electronegative atom (e.g., N, O, F, etc), and another electronegative atom.

- base stacking interactions that result from the arrangement of RNA nucleotides

In this case, it is also important to highlight that the interaction will depend on the specific tertiary structure of ribosomal proteins and ribosomal RNAs (rRNAs).
