Answer:

48 chromosomes

Explanation:

The genetic condition described in the question is referred to as ANEUPLOIDY, which is a chromosomal disorder. ANEUPLOIDY occurs when there is an extra or missing copy of a chromosome in the normal set of chromosomes. It occurs mainly due to the fusion of an abnormal gamete.

A karyotype shows that human cell consists of 46 chromosomes in total I.e. 22 pairs of body and 1 pair of sex chromosomes. A human is a diploid organism I.e. contains two set of chromosomes. This means that one set of chromosomes (haploid, 23 chromosomes) is contributed by one parent.

Therefore, in a case whereby, an extra copy of a pair of homologous chromosomes is contained in the genome of a human. Hence, this will be 2n + 2 which means 46 chromosomes plus two extra chromosomes = 48 chromosomes. This ANEUPLOIDY likely resulted from the fusion of two abnormal gametes that are n+1 each.

D. step 4

Explanation:

the cell divides into two daughter cells during meiosis 1

Answer:step 4

Explanation:

In meiosis, the breaking up of chromosomes occur to form new daughter cells. The chromosomes break into haploid parts and then the two daughter cells formed then twist and exchange their genetic information. Division into four daughter cells is less likely to occur during meiosis 1.

Answer:

1) 945000 m

2) 6.11 miles/hour

3) 3.52 seconds

Explanation:

1. Speed is the time rate of change of distance, it is the ratio of distance to time. Speed is given by the equation:

[tex]speed(S)=\frac{distance(d)}{time(t)}[/tex]

Given that:

Time (t) = 9 hours and Speed (S) = 105 km/h

[tex]S=\frac{d}{t}\\ d=S*t=105*9=945km=945000m[/tex]

2) Time (t) = 0.9 hours and distance (d) = 5.5 miles

[tex]S=\frac{d}{t}\\ S=\frac{5.5}{0.9} =6.11miles/hour[/tex]

3) Acceleration it is the ratio of velocity to time. Acceleration is given by the equation:

[tex]Accceleration(a)=\frac{Final,velocity(u)-initial, velocity(v)}{time(t)}[/tex]

Given that :

a = 4.2 m/s² , u = 18.9 m/s and v = 33.7 m/s

[tex]a=\frac{v-u}{t}\\ t=\frac{v-u}{a}\\ t=\frac{33.7-18.9}{4.2}=3.52s[/tex]

Answer:

1) 945.000 meters

2) 9,84 kilometers/hour

3) 3,52 seconds

Explanation:

1) 105 km/h x 9 h = 945km

1km = 1000 meters    945 km = 945.000 meters

2) 1 mile = 1.61 km

5.5 miles x 1.61 km / 1 mile = 8,855 km

You have to do a single third rule to clear the x which is the Ann's velocity in 1 hour.

8,855km in 0.9 hs

x (velocity in 1 hour) = 9,84 km =   1 hs

1 hs x 8,855km / 0,9hs = 9,84km/h

v= 9,84km/h

3) you have to use this formula and clear T (time)

vf = v0 + a.t

vf-v0 = a.t

(vf - v0)/a = t

(33.7 m/s - 18.9 m/s) / 4.2 m/s2 = 3,52 seconds

Answer:

D. Prokaryote

Explanation:

The Linnaean system of naming consists of domain, kingdom, phylum, class, order, family, genus, and species. I remember it with "D- King Phillip Came Over For Great Soup".

I hope this helps!

Final answer:

The classification 'Prokaryote' is NOT part of the Linnaean system of naming; Carl Linnaeus's system includes Genus, Species, and Class among other ranks.

Explanation:

Swedish scientist Carl Linnaeus is renowned for creating the first comprehensive taxonomy system in the 1700s, which is crucial for the science of taxonomy, the classification and naming of organisms. The Linnaean system includes a hierarchical structure with several levels of classification, including Kingdom, Phylum, Class, Order, Family, Genus, and Species. Notably, Linnaeus is responsible for introducing binomial nomenclature, where each species is given a two-word name, with the first word indicating the genus and the second the species itself.

The correct answer to the student's question is D: Prokaryote. This term refers to a broad grouping of organisms that do not have a nucleus, which falls outside the hierarchical ranks established by Linnaeus. Instead, the classifications within the Linnaean system are Genus, Species, and Class, making Prokaryote the classification not part of the Linnaean system of naming.

Correct option is A. The shift from light to dark-colored moths due to environmental changes during the Industrial Revolution is an example of directional selection, as the darker moths had a higher survival rate.

The transition of light-colored moths to dark-colored moths in an original population after natural selection occurs is a classic example of directional selection. During the Industrial Revolution in nineteenth-century England, the environment changed due to the soot from factories darkening the trees. This led to light-colored peppered moths, which were originally well-camouflaged, becoming more visible to predators, while dark-colored moths became more camouflaged. As a result, the dark-colored moths had a higher survival rate, leading to an increase in their frequency over time, shifting the moth population from light to dark.

Answer:

B. They last much longer than traditional lightbulbs

The important quality which is an advantage of LED lightbulbs over normal lightbulbs is they last much longer than traditional lightbulbs. Thus, the correct option is B.

An LED lamp or the LED light bulb is an electric light which produces light using the light-emitting diodes. LED stands for Light Emitting Diode. LED lamps are significantly much more energy-efficient than the equivalent incandescent traditional lamps and these can be significantly more efficient than that of most of the fluorescent lamps.

LED lightbulb products produce light up to 90% more efficiently than the incandescent light bulbs. An electrical current passes through a microchip which is responsible for the illumination of the tiny light sources which we call LEDs and the result is the visible light.

LED lightbulbs have longer life as compared to the incandescent lamps. LED lightbulbs require low operational voltage and also less power as compared to that of incandescent lamps. LEDs also have a fast on-off switching capability.

Therefore, the correct option is B.

Answer:

Billions of dollars of foreign aid has poured into Haiti with little to show for it. This is largely because that money has come to do for Haitians what, with a little help in expertise, they could have done for themselves. This is the biggest difference between aid and development. As a result, 74% of Haitians are either unemployed or under-employed and 8.5 million live on less than $2.41 per day.

Aid is designed to help with immediate needs. As important as that is at times, aid is not the solution to Haiti’s long term challenges. The Haitian people are the solution to Haiti’s problems, particularly those who have the skills and character to build a stronger Haiti for all.

By helping men and women gain the skills to build, train, and lead, you have the power to unleash Haiti’s potential to create a stronger future.

The earth began as a cloud of dust and hot, shining gas. When our planet began to cool, its surface solidified, surrounded by clouds of water vapour. When this vapour condensed (changed into liquid) and began to fall like rain, seas, and oceans formed in the hollows of the Earth’s surface. Oceans are huge expanses of water which separate the Earth’s continents. The largest ocean is the Pacific Ocean, second, the Atlantic and third largest, the Indian Ocean. Seas are smaller expanses of water, almost always flowing either into oceans or other sea. The waters of the seas and the oceans are always salty, because they are rich in mineral salts and especially sodium chloride, which is the salt used in cooking.

Answer:

In anaphase II, the sister chromatids separate, and in anaphase I the homologous chromosomes separate.

Anaphase I and II, part of meiosis, differ based on what is being separated. Anaphase I separates homologous chromosomes while anaphase II separates sister chromatids.

The major difference between anaphase I and anaphase II is the separation of different structures. In anaphase I of meiosis, homologous chromosomes are separated, while in anaphase II, the sister chromatids are separated. It means, that in anaphase I, the paired chromosomes (tetrads) move to opposite ends of the cell, whereas in anaphase II, the sister chromatids of each chromosome split apart and move to opposite ends of the cell.

This difference is because anaphase I occurs during the first meiotic division (meiosis I), where cells are reduced from diploid to haploid. Whereas, anaphase II happens in the second meiotic division (meiosis II), which does not reduce chromosome counts and is, therefore, more similar to mitosis.
