Answer:

Temperature refers to how warm or cold air is, and the density of the air is how many molecules are packed into a certain space of air. Air pressure is influenced by temperature because, as the air is warmed, the molecules start moving around more, so they bump into each other more often and create more pressure.

the pressure patterns associated with global circulation patterns. On the equator areas, since air is heated and rises, a zone of lower pressure will result.

Explanation:

at the equator the air is moist and hot and when air is hot it's density decreases and so does the pressure exerted by it. and also air that contains water vapour is less denser than the air containing no or less water vapour so air containing less water vapour exerts more pressure

Which effect is most likely caused by nondisjunction during meiosis?

Reil [10]

The answer to the question would be an extra chromosome.

Meiosis is a type of cell division which all sexually reproducing diploid eukaryotes have. It is finished in the process of fertilization, resulting in a zygote. The chromosome number is divided by half in this process, resulting in four haploid cells which all differ genetically from the parent cells. After DNA replication, two cell divisions take place, referred to as Meiosis I and Meiosis II. The first cell division generates the diversity of genetic information through the process of crossing over and random positioning of homologous chromosomes. The number of chromosomes is here reduces from diploid (2n) to haploid (n).

In order to achieve genetic diversity, the homologous chromosomes need to separate in the first meiosis, and then the sister chromatids need to separate in the second meiosis, which brings us to four haploid cells. Nondisjunction is an error in this process that can happen in either the separation of homologous chromosomes, or the separation of sister chromatids. The result of nondisjunction in a chromosome imbalance, so a cell that has been affected by nondisjunction is an aneuploid cell. There are different types of aneuploidy, like monosomy (the loss of one chromosome), trisomy (the gaining of one chromosome) and different syndromes can occur as a result of this erroneous process.

Out of the answers you provided, gaining an extra chromosome would be the answer, but a single chromosome loss can also be the result of nondisjunction.

Nerves designated by Roman numerals and by names that indicate their primary functions and/or the general distribution of the th

nasty-shy [4]

Cranial Nerves are paired nerves, since there is one for each side of the body, there are a total of 12 nerves and they are named with Roman numerals and by names that indicate their primary functions.

<h3>What are Cranial Nerves?</h3>

They are a set of nerves that come directly from the brain, unlike the rest of the nerves of the nervous system.

Each pair is numbered with a Roman numeral depending on whether the position from which they leave the brain more or less near the frontal area.

Therefore, we can conclude that Cranial Nerves are paired nerves, since there is one for each side of the body, there are a total of 12 nerves and they are named with Roman numerals.

The labels beside the heart (2):

Sinoatrial Node (SA node)

Atrioventricular Node (AV node)

The labels inside the wave image(5):

From LEFT to RIGHT (top to bottom):

Atrial depolarization

P wave

Ventricular depolarization

Ventricular repolarization

T Wave

Please look at the attached picture for clarification.

Here is more about your question:

The images depict the electrical conduction system of the heart.

The sinoatrial node (SA node) is located in the right atrium. It works as a pacemaker of the heart. It starts all the heartbeats and the heart rate. It spreads electrical impulses throughout both atrias, to stimulate them to contract.

The AV node is like a gateway for electrical impulses. It delays the electrical impulses going towards the ventricles to make sure that all the blood from the atria is emptied into the ventricles before contraction.

The next image is an ECG reading. It shows the action potentials that are produced by the nodes and cells of the heart.

Each wave and segment of the image shows an event that occurred in the heart as it was recorded.

P-wave occurs when the atria depolarizes. This happens when the atria fills up with blood, which initiates the SA node. The SA node then spreads electrical signals and causes them to depolarize.

QRS complex is the point where ventricular depolarization occurs.

Q-wave, the interventricular septum depolarizes;
R-wave, the main mass of the ventricles depolarizes;
S-wave, the rest of the parts left near the base of the heart of the ventricles depolarizes.

T-wave indicate ventricular repolarization which happens right before the relaxation of the ventricles. At this point, the cycle will repeat.

This cycle will repeat in every heartbeat.

Like DNA, RNA contains four nitrogenous bases. Three of them are the same as those found in DNA. The one that is different is ca

antoniya [11.8K]

Answer:

RNA has for nitrogenous bases out of which three are the same as DNA. The bases common to both DNA and RNA are Adenine (A), Guanine (G) and Cytosine (C). The one that is different is called Uracil (U).

The five carbon sugar in RNA is called Ribose sugar.

Explanation:

DNA consist of four bases that are A,T,C and G. Similarly, RNA also consists of four bases that are A,U,C and G.

Thymine (T) is not present in RNA, instead of it, RNA has Uracil (U) which binds with Adenine (A) by two hydrogen bonds.

The five-carbon sugar that is present in RNA is ribose and that present in DNA is deoxy-ribose. Ribose and deoxy-ribose differ at second carbon. Ribose has an OH at second carbon while in deoxy-ribose, O is missing at second carbon and it has only H.

How many organisms represented are multicellular?

Sladkaya [172]

All of the organisms are multi-cellular.
Fungus, belonging to the fungi kingdom,
Green plant, belonging to the plant kingdom,
Spider and Birds, belonging to the animal kingdom.
All of the above kingdoms are made up of only multi-cellular organisums, excluding some yeasts in the fungi kingdom.
Good luck!
