The African clawed frog (Xenopus laevis) is allotetraploid, likely as a result of an interspecies mating long ago, followed by a
stepladder [879]

Explanation:

Xenopus laevis is allotetraploid: it has 2 sets of homologous chromosomes originally from one species and 2 sets of homologous chromosomes originally from another species, making a total of 4 sets of chromosomes. During meiosis, every chromosome has another homologous one with which it can pair, producing viable gametes that have the complete genetic information of the species.

Mules, however, are allodiploid: they have one set of chromosomes from a donkey and another set from a horse, making a total of 2 sets of chromosmes. But those two sets are not homologous, so during meiosis the chromosomes can't pair and the gametes will have errors that make them inviable, making mules sterile

______________ is a statistical procedure that can be used to identify clusters of behaviors that are related to a trait.
Mamont248 [21]

Answer:

Factor  Analysis

Explanation:

Factor Analysis is a statistical procedure that can be used to identify clusters of behaviors (such as verbal skills, intelligence) that are related to a trait.

Factor analysis helps to accumulate a lot of data in many variables into a few variables which can be used for further analysis or study. The aim of factor analysis is to aggregate individual behaviors into a minimized number of factors.

There are more protons than electrons in a negatively charged atom.
meriva

Answer:

False.

Explanation:

Protons are positively charged, so having more protons would make an atom positively charged. Electrons are negatively charged.

The cell cycle of yeast cells grown in the nutrient-poor environment is approximately what percent of the cell cycle of yeast ce
vova2212 [387]

Answer:

Upon nutrient limitation, budding yeast will produce daughter cells less than 20% of the mother cell size. This asymmetric division may select for growth functions that are efficient over a larger range in cell sizes, such as exponential growth. In turn, efficient growth over a large size range lessens the pressure to have precise size control.

Explanation:

In wild-type cells growing in nitrogen-rich medium, the size threshold to enter mitosis is high, and the G1/S size control is cryptic because cell division produces daughter cells with a size greater than the minimum required to initiate S phase. In these conditions, G2 is long and G1 is short. However, the cell size threshold to enter mitosis is greatly reduced when wild-type cells are shifted to medium with a poor nitrogen source, such as minimal medium with proline, isoleucine, or phenylalanine. In these conditions, wild-type cells initiate mitosis at a reduced cell size, generating two daughter cells that are smaller than the critical size threshold required to progress through G1/S
