Which type of cell might have been the first one to evolve and explain why this may have been the first.
The hypothesis that eukaryotic cells evolved from a symbiotic<span> association of prokaryotes—endosymbiosis—is particularly well supported by studies of mitochondria and chloroplasts, which are thought to have evolved from bacteria living in large cells.</span>
Compare and contrast eukaryotic cells with prokaryotic cells.
Eukaryotic cells contain membrane-bound organelles, including a nucleus. Eukaryotes can be single-celled or multi-celled, such as you, me, plants, fungi, and insects. Bacteria are an example ofprokaryotes. Prokaryotic cells do not contain a nucleus or any other membrane-bound organelle.

Nadusha1986 [10]

Answer:

For an individual who is heterozygous for two genes, Aa and Bb, what does independent assortment predict? Offspring inheriting the recessive allele

of the first gene will also inherit the dominant

Explanation:

Aa x Bb= AB, Ab, aB and ab

so the first gene will also inherit the dominant gene

An organism's inherited traits that increase its likelihood to reproduce and survive are the traits it will most likely pass on

galben [10]

This pattern can be explained by the principle of natural selection. Natural selection. Natural selection is one of the basic mechanisms of evolution, along with mutation, migration and genetic drift. In natural selection those variations in the Genotype that increase the organisms chances of survival and procreation are preserved and multiplied from generation to generation at the expense of less advantageous ones.

docker41 [41]

Answer:

undergo irreversible repression

Explanation:

Cellular differentiation refers to the process by which one cell and/or cell population divides and differentiates into more specialized cells. During cell fate differentiation, epigenetic marks modify chromatin structure in order to hamper the accessibility of the transcriptional machinery and transcriptional factors to different genes, which are irreversibly repressed. These epigenetic marks include DNA methylation and histone modifications (e.g., histone acetylation, histone methylation, etc). For example, it has been shown that DNA methylation and histone H3 lysine 27 tri‐methylation (H3K27me3) are epigenetic repressive marks on genomic regions that play a major role in gene expression programs during cell fate differentiation.
