Answer:  30-40%

Explanation:

The estimated figure is that spontaneous abortion occurs in approximately 1 in 4 recognized pregnancies, with 85% of those occurring in the first trimester (weeks 1 to 12). A 'late' miscarriage, which is much less common, can occur between weeks 13 and 24 of pregnancy.

Where a miscarriage usually occurs in the first 3 months of pregnancy, before 12 weeks of gestation. A small fraction of pregnancy losses, which occurs in less than 1% of pregnancies, are called fetal deaths, since they occur after 20 weeks of gestation.

Prokaryotes divide by binary fission, a form of asexual reproduction in which a cell divides into two cells with identical genetic information.

Explanation:

Binary fission and mitosis can be viewed as the same principle of  asexual reproduction to give out two identical cells. However, the major difference between the two is that binary fission is to prokaryotes and mitosis is to eukaryotes. Remember that prokaryotes do not have a true nucleus (they have a nucleoid) hence binary fission does not involve the dividing of the nucleus. Mitosis does.

Sexual reproduction is responsible for creating variation in offspring especially due to the process of meiosis in gamete development and subsequent fertilization of two gametes from different parents.

This is a di-hybrid problem. When doing a punnet square for di-hybrid problems, I would suggest using the F.O.I.L method to determine how to place the alleles. 

Since both individuals are heterozygous, they will be both PpLl x PpLl.

By doing the punnet square, I get the answer of D.

Is the Gram stain a useful tool for understanding the phylogeny of eubacteria? Explain why or why not.
natita [175]

Answer

Yes, Gran stain is a useful tool for unterstanding the phylogeny of eurobacteria.

Explanation

The Gram staining method is used to classify two broad groups: gram-positive and gram-negative bacteria. This technique is widely used in clinical analysis and microbiology laboratories to monitor infections in pus smears or organic fluids.

In the Gran staining method, we subject the bacteria to dye treatments and, depending on the chemical composition of the cell wall of these bacteria, each one will react differently with the dyes and thus identify them by their biochemical characteristics.
