The segregation that occurs during meiosis results in a

Biology
1 answer:
Grace [21]3 years ago
4 0

The correct answer is option B, that is, reduction in the number of chromosomes per cell.

Meiosis refers to a unique kind of cell differentiation, which minimizes the number of chromosomes by half, forming four haploid cells, each genetically different from the parent cell from which they originated.

This procedure takes place in all the sexually reproducing single-celled and multicellular eukaryotes, including fungi, animals, and plants. In meiosis, the replication of DNA is succeeded by two rounds of cell differentiation to generate four daughter cells, each with half the number of chromosomes as the main parent cell.

Single-celled eukaryotes arose from prokaryotes. Later, which larger, more complex organisms did they evolve into?
sdas [7]
A l,ll,lll and lV would be the answer because a eukaryote is an organism with complex cells, or a single cell with a complex structures. In these cells the genetic material is organized into chromosomes in the cell nucleus. Animals, plants, algae and fungi are all eukaryotes. There are also eukaryotes amongst single-celled protists.

What would happen if there was no condensation stage in the water cycle
BigorU [14]

Condensation is the process by which water vapor is changed back into liquid water. Condensation is very important to our weather and climate because it is what is responsible for cloud formation.

Without clouds, we would not get to the third phase, called precipitation, which we will talk about in a minute. Clouds form when water vapor condenses around small particles, like bits of dust or smoke in the air. Depending on the size of the drops, these particles may or may not be visible. Even on a clear, cloudless day, water vapor is always present in the atmosphere, but it does vary in amounts. We know it is present on a very humid day; it often feels like we need to swim through the air! Fog is condensation near the ground.

<span>Fog forms when moist warmer air comes in contact with cooler air near the surface. Just like when the bathroom mirror gets all foggy during a shower because of condensation, fog also forms because of this warm air contacting a cooler air mass. The fog forms drops in the air rather than on the surface of your mirror.</span>Clouds will be useless since they will not carry and drop water.

Fill in the Punnett square below to visualize the offspring of a cystic fibrosis carrier and a person who doesn't have cystic fi
valkas [14]

Answer:

50% of their children are likely to be carriers of cystic fibrosis

Explanation:

Since the normal allele "F" will be the dominant allele while the mutated CFR allele "f" will be the recessive allele, <u>the gene (pair of alleles) of the person that is a CFR carrier will be "Ff" while that of the normal person who isn't a carrier will be "FF"</u>. The attachment shows the crossing between the two parents. From the illustration in the attachment, for every 4 children given birth to, 2 of them will likely be normal, "FF", (not a carrier and doesn't have cystic fibrosis) while 2 others will likely be carriers of cystic fibrosis (Ff). Hence, 50% of their children are likely to be carriers of cystic fibrosis.

Explain about hemichordata...​
Alexandra [31]

Answer:

The term Hemichordata—from the Greek hemi, meaning “half,” and chorde, meaning “string,” thus, “half-chordate”—was first proposed because the buccal diverticulum, a tubular outgrowth from the mouth cavity forward into the proboscis, or “snout,” resembled a rudimentary notochord—the dorsal, o

horsena [70]
This means that balls with a diamenter of 2.25 inches cannot have any imperfections (bumps or dents) greater than 0.005 inches. In other words, the bump or dent to diameter ratio cannot exceed 0.005/2.25 = 0.0022222
