In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I. D

Answer:

Examples of abiotic factors are water, air, soil, sunlight, and minerals. Biotic factors are living or once-living organisms in the ecosystem. These are obtained from the biosphere and are capable of reproduction. Examples of biotic factors are animals, birds, plants, fungi, and other similar organisms.

dimaraw [331]

Answer:

Evolution.

Explanation:

The unique method of locomotion in octopus has been utilized by successive generations of octopus through the process of evolution. Evolution is defined as the change in the characteristics of a species over several generations. This type of behaviour is attain by octopus in order to save itself from its predators such as shark so we can say that this unique method of movement is used by octopus to save itself from the predators leads to evolution in the octopus.

many organisms that undergo chemosynthesis use instead of to fuel the processes that convert carbon dioxide into sugars.
OLEGan [10]

Answer:

Many organisms that undergo chemosynthesis use hydrogen sulphide (H2S) instead of sunlight to fuel the processes that convert carbon dioxide into sugars.

Explanation:

Prokaryotic microorganisms, principally bacteria and archaea (referred to as “bacteria” in the following), carry out chemosynthetic reactions. Energy is produced in chemosynthetic reactions from oxidizing reduced compounds.

Chemosynthesis is the conversion of carbon (usually carbon dioxide or methane) into organic matter using inorganic molecules (hydrogen or hydrogen sulphide) or methane as an energy source. Most energy is initially derived from sunlight via plant photosynthesis. Example, bacteria and methanogenic archaea living in deep sea vents

What do we mean when we refer to a cell as differentiated?
Otrada [13]

Answer:

We mean that a cell changes to another type of cell.

Explanation:

<em>Stem cells </em>are a type of cell that has the potential to become a specialized cell, this change or differentiation, is possible thanks to the activation or deactivation of certain genes that promote (or inhibit) the expression of certain proteins that origins different types of cells (fmuscle cells, osteocytes, neurons). This differentiation happens when the cells receive cues internally ( through signals or contact between a group of cells and another or through transcription factors) or externally.

Then, a differentiated cell is a cell that had gone under the previously described process.

I hope this information is useful to you!
