At the end of Meiosis II, each daughter cell has 23 single-stranded chromosomes.
Rainbow [258]

Answer:

y the end of meiosis, the resulting reproductive cells, or gametes, each have 23 genetically unique chromosomes. ... Each daughter cell is haploid, because it has half the number of chromosomes as the original parent cell.

Explanation:  

30 chromosomes

Each daughter cell will have 30 chromosomes. At the end of meiosis II, each cell (i.e., gamete) would have half the original number of chromosomes, that is, 15 chromosomes. 2.

From a diploid germ cell 2n =24 double stranded chromosomes, meiosis will produce four gamete haploid cells n =12 single stranded chromosomes.

Meiosis produces four with half because double stranded chromosomes represents DNA replication. Twice as much DNA as a diploid cell needs.

From a diploid germ cell 2n =24 double stranded chromosomes, mitosis will produce two diploid daughter cells 2n =24 single stranded chromosomes for the same reason.

DNA replication doubles the genome before cell division. Sister chromatids of double stranded chromosomes represent the replicated DNA. During cell division, sister chromatids of double stranded chromosomes are separated into different cells.

Meiosis has two stages, the first separating homologous pairs of double stranded chromosomes, and then the second stage separating sister chromatids into four haploid (n) gametes.

Yakvenalex [24]

Answer:

Basically , male sex  cells  are  determined by the XY combination; heterosomes, (while the female sex cells by the XX). <u>Since  it is the Y chromosomes present in  the father only that determines the  male sex of the child and therefore the proof of paternal inheritance ' the women in the class will not be able to participate in the inheritance analysis.Due to  lack  of  the Y -chromosomes.</u>

Similar rock formations have been discovered in Brazil and South Africa. These rock formations were formed at the same time and
makkiz [27]

Answer:

continental drift

Explanation:

The most likely reason for this would be continental drift. It is believed that millions of years ago our world was one giant continent. This continent began breaking apart and drifting slowly more and more as millions of years passed by, ultimately creating the seven continents we know now. This would mean that Brazil and South Africa were most likely once the exact same location or the edge of where the continent broke apart. This would explain why the same rock was found in both locations.

How does the shape of the vomerine teeth help it preform its function(holding prey) This is about frogs btw
Margarita [4]

Answer:

The shape in V of the vomerine teeth is useful to hook the prey and hold it until the frog can swallow it.

Explanation:

In frogs, we can distinguish maxillary teeth, premaxillary teeth, and Vomerine teeth.

Vomerine teeth are projections of the vomer bone, located in the anterior part of the paladar and between the internal nares.

Vomerine teeth are specialized structures that help frogs catch and hold their prey. They are not involved in chewing or killing (frogs swallow the entire prey alive), just holding the creature before swallowing it.

These projections are covered by soft tissue. When the frog catches the prey, presses the tongue against the roof of your mouth. The vomerine teeth hook the prey and prevent it from slipping or wandering away.

The shape in V of the vomerine teeth is useful to hook the prey and hold it until the frog can swallow it.
