An engineer is building a new steel skyscraper in a area with a lot of Earthquakes, Compare two systems (fixed based system and

Leokris [45]

Answer:

<h2>Base isolated system</h2>

Explanation:

Fixed based system:-

A fixed-base building (built directly on the ground) will move with an earthquake’s motion and can sustain extensive damage as a result.

Base isolated system:-

A base isolation system is a method of seismic protection where the structure (superstructure) is separated from the base (foundation or substructure).

Hence,

A base isolated system is much more better in a area where there are a lot of earthquakes.

During which phase of meiosis does each of the following events occur?

lubasha [3.4K]

Answer:

(a) crossing over: Meiosis I, Recombination

(b) chromatids separate at their centromeres and migrate to opposite poles: Meiosis II, Anaphase II

(c) chromosomes become aligned in pairs at the equator: Meiosis II, Metaphase II

Explanation:

Homologous recombination is a type of genetic recombination that occurs during meiosis (formation of ovum and sperm cells). The paired chromosomes of the male and female parents are aligned so that similar DNA sequences intersect. This crossing over produces an exchange of genetic material, which is an important cause of the genetic variability observed in the offspring.

Meiosis II: Anaphase II. The centromeres separate and the daughter chromatids - now individual chromosomes - move to the opposite poles of the cell. The centromeres separate, and the two chromatids of each chromosome move toward the opposite poles in the spindle.

Meiosis II: Metaphase II. Chromosomes are accommodated in the equatorial plate of metaphase, similar to what happens in mitosis. They are attached to the already fully formed meiotic spindle. Each chromosome is aligned in the equatorial plate of the metaphase, as it happens in mitosis.

We think of termites as insects that “eat” wood. In fact, however, termites rely on a variety of eukaryotic and prokaryotic gut

Ivenika [448]

Answer:

Symbiosis

Explanation:

Termites are the important insects due to its role in in nutrient recycling in the terrestrial ecosystems. Termites eat wood. The wood contain cellulose, a complex carbohydrate which is cannot be digested by most insects such as termites. For the breakdown and digestion of wood is carried out by the microorganisms present in the hindgut of the termites. The microbes live in the gut as a symbiont. The microbes break down cellulose into simple sugars and fatty acids which are easily absorbed into the cells of the termites.
