What is the function of the slip rings in an electric generator?

keeping current flowing in one direction

stopping current from leaving the generator

producing a path for current to flow

preventing the armature from spinning

Answer:

The correct answer is option C, that is, have a wider range of environments.

Explanation:

It has been known that geographic isolation is a general way for the initiation of the process of speciation, like the rise of mountains, rivers changing course, migration of organisms, continental drift, due to this what was once a steady population gets differentiated into two or more kinds of smaller populations.  

A mountain range, due to distinctions in temperature and precipitation as a result of different altitudes, can lead to a higher rate of speciation. Due to these differences, a single mountain range can exhibit an enormous array of biodiversity and climate zones.

In comparison to populations living in broad, open grasslands, populations living on rocky, steep mountains would experience a higher rate of speciation due to the mountain's ability to divide populations into smaller subgroups . So, the correct option is C.

Geographic isolation is known to be a common way for the beginning of the process of speciation, similar to the formation of mountains, the alteration of rivers, the migration of organisms, and continental drift. As a result, what was once a stable population becomes divided into two or more different kinds of smaller populations.  

A mountain range might result in a greater amount of speciation because to differences in precipitation and temperature as a result of various altitudes. A single mountain chain can display a huge variety of biodiversity and temperature zones as a result of these variances.

Therefore, the correct option is C.

Answer:

D

Explanation:

Dominant and the recessive allele are the traits present in the genes that get inherited from the parent to their offspring.

The trait that is visible in the phenotype is called dominant while the trait that gets masked in the proximity of the dominant allele is called recessive.

The correct answer is:

Option C. Jessica inherited one recessive form of the gene from each parent.

This can be explained by :

See the attached image below for the cross:

The genes gets independently assorted and Jessica inherits the recessive form of the genes from both of her parent.

Therefore, Jessica inherited recessive gene one from each parent.

Answer:

The answer is True.

Answer:

A. 14.59

Explanation:

Firstly, rounding a number means making a number simpler but keeping its value close. So rounding 14.587020 means making it look less complex but making sure the rounded value is within range of the original value.

Next, we have to know that to round a number;

* Digits below 5 (<5) rounds down the next digit to their left i.e. we leave the digits the same and turn the rounding digit to 0.

* Digits above 5 (>5) rounds up the next digit to the left i.e. we add 1 to the next digit

Next, to round to 4 significant digits means we want to see only the first four non-zero digits in our value. Note that, all non-zero digits i.e. 1-9 are significant

Hence, 14.587020 will be:

= 14.587020

= 14.58700

= 14.59000

We have four (4) digits which are non-zero already, hence we stop here and remove all zeros to the right

Hence, 14.587020 to 4 significant digits is 14.59 i.e. 14.587020 ~ 14.59

Answer:

I wasn't quite sure what virus you were referring to in your question, but here's a general answer: Viruses use their host cells' machinery to replicate themselves.

If they are a specific type of virus known as a retrovirus, they have the ability to use the host cells' enzymes to change the RNA contained within the virus into DNA (via some type of replication I suppose).

In other cases, if they contain DNA instead of RNA (that is, the virus), they can use the host cell's machinery to create RNA via enzymes involved in transcription and/or they can incorporate that DNA into the host cell's DNA. This is part of a type of viral replication cycle known as the lysogenic cycle.

In another type of viral replication cycle known as the lytic cycle, the virus simply has itself and its genome duplicated until the host cell bursts, releasing the viral material. Here, again, the virus uses the host cell's machinery to replicate itself.

Explanation:

the large brown plate is   pacific plate was under the ocean and also named after the ocean pacific ocean. so it is easy to guess

hope you understood it . it was my explanation up for more info down i have pasted what they told in google.

Pacific plate

In fact, six of the seven major tectonic plates are named after the continents they contain. The one exception is the Pacific plate, which lies beneath the Pacific Ocean. Not only is this the only major tectonic plate that is mainly underwater, it is also the largest, spanning over 100 million square kilometers.

Pacific Plate. The Pacific Plate is an oceanic tectonic plate that lies beneath the Pacific Ocean. At 103 million km2 (40 million sq mi), it is the largest tectonic plate. The Pacific Plate contains an interior hot spot forming the Hawaiian Islands.

Answer:

It has four valence electrons, which it can achieve a full outer energy level which forms four covalent bonds. When its bonds only with hydrogen, it forms compounds which is called hydrocarbons. Carbon can be form in single, double, or triple covalent bonds with other carbon atoms.

Explanation:

The valency of carbon is four. Therefore, carbon can form four chemical bonds.

It is the attraction between two atoms, they share or exchange electrons to form molecules or compounds is known as a chemical bond. They share electrons to fulfill their valency. The number of bonds depends on the number of valencies.

There are three types of bonds and that are covalent, ionic, and metallic bond. A covalent bond or molecular bond is formed by sharing of electrons, it occurs in non-metals. Ionic bonds are formed by exchanging electrons, it occurs in both metal and non-metal. metallic bonds are present between two metals. The covalent bond is the strongest bond.

There are four valencies in carbon. Therefore, it can make four bonds.

Explanation:

DNA utilizes four bases, adenine (A), guanine (G), cytosine (C), and thymine (T), in its code. RNA also uses four bases. However, instead of using 'T' as DNA does, it uses uracil (U). Therefore, if your DNA sequence is 3' T C G T T C A G T 5', the mRNA sequence would be 5' A G C A A G U C A 3'.
