Calcium ion can be combined with oxygen ion to form an ionic compound.
What is Ionic compound?A compound that is created through ionic bonding is known as an ionic compound. One atom transfers its electrons to another in a process known as electron transfer to form an ionic connection. Think about two pups.
The pups each have a bone. The puppies stand in for atoms. The bone is a metaphor for an electron. Both of the puppies are impartial. One dog snatches the bone from the other since it is a thief. Now that the bone is his, the puppy thief.
In order to create a puppy pair with the thieving puppy, which has a negative charge, the puppy without a bone, which has lost an electron and is now positively charged, will follow it about. The ionic compound is the puppy pair.
Therefore, Calcium ion can be combined with oxygen ion to form an ionic compound.

Differences in ocean salinity and temperature create...
...disturbances in the water cycle.
...different climates on land.
...masses of water that are different from each other.
...weather patterns with a lot of fresh water precipitation.
Answer:
Masses of water that are different from each other
Explanation:
salt water is denser than fresh water, so it makes sense that it would create masses of water that are different from each other, it won't affect the water cycle climate or weather cycle since the salt stays in salt water when it is evaporated, creating precipitation that is always fresh water.

What type of circulatory system do mollusks have? Which animal in this phylum is the
exception?
Answer:
Molluscs with the exception of cephalopods have an open circulatory system I.e.the blood circulates with in vessels from the heart but it also fills open lacunas or cavities. In annelids the cieculatory system is closed, i.e. the blood circulates only inside blood vessels.
Jill has quite a menagerie of pets and she regularly has to deal with minor animal injuries. So when Johnnie, her rooster, spikes Jessie, her collie, on the muzzle with one of his long leg spurs, Jill knows what to do. She reaches for the hydrogen peroxide and thoroughly floods Jessie's puncture wound with the liquid. Jill observes, as always, that the hydrogen peroxide causes heavy fizzing at the site of the wound. She repeats the procedure several times a day over the next week, carefully inspecting the wound for signs of infection. The injury heals without complications and Jessie has a new respect for roosters.
a) What is hydrogen peroxide and how does it help to reduce the infection?
b) Why is hydrogen peroxide especially useful for treating puncture wounds?
c) What causes the fizzing associated with hydrogen peroxide use?
Answer:
a.) Hydrogen peroxide are highly reactive oxygen compounds used as an antiseptic
b.) Used in treating punctured wounds due to the nature of the wound which helps microorganisms to thrive.
c.) Fizzing associated with hydrogen peroxide use is due to presence of the enzyme catalase.
Explanation:
Hydrogen peroxide is a chemical compound which is made up of two hydrogen atoms and two oxygen atoms. It is powerful oxidizing agent which takes part in biological reactions. This is possible as it can remove electrons from other biological molecules which can damage other cellular components. It is used an an antiseptic to reduce infection because, being a powerful oxidizing agent, it has the ability to react with cell wall of these microorganisms through removal of electrons thereby causing damage to it.
Punctured wounds are narrow in structure which allows obligate anaerobic organisms to thrive because of reduced oxygen flow in the wound. Hydrogen peroxide can effectively eliminate these organisms which are most likely to cause infection in that site because they lack the enzyme called catalase.
Catalase is an enzyme which is present in living cells except obligate anaerobic organisms. It converts hydrogen peroxide into water and oxygen. The fizzing noticed by Jill while cleaning the wound with hydrogen peroxide is due to the catalase in Jill's own cells which converts the hydrogen peroxide to water and oxygen. When oxygen is given off, fizzing reactions are seen at the surface of the wound.

A small group of diploid triangular Sticky Notes were fluttering along the coast of The Mainland. A storm blew in and blew the Sticky Notes to an isolated island that had never previously been inhabited by Sticky Notes. After a few years, the Sticky Note population (though still small) has happily made the new island their home and are visited by an evolutionary biologist. The evolutionary biologist bands the Notes, collects tissue for a genetic analysis, and finds that this isolated population of Notes is not in Hardy-Weinberg equilibrium. Why is this, and what may be the potential long-term significance
Answer:
Because genetic drift (Founder effect) is acting on this population. Not all the Hardy weinberg criteria are accomplished. There are no random matings and populations are finite-sized.
Explanation:
This is a special case of genetic drift: the founder effect.
The “Founder effect” phenomenon refers to cases where a new population originates from a few founder individuals, coming from a bigger ancestral population, that established in a new environment. This small population might or might not be genetically representative of the original one. This subgroup carries with them some genetic information that they share with their original population. Over time, some genes can be lost, or they can increase in frequency. Some rare alleles might be exceeded or might be completely lost. On Consequence, when the small population grows, it will have a genetically different composition from the original one. In these situations, genetic variability is reduced and enhances the possibility of developing a peculiar allelic composition. In some cases, the founder effect is part of the process of speciation.
The criteria for maintaining a Hardy-Weinberg equilibrium are:
Random matings No superposed generations No mutations No migration Infinite population size No natural selectionGenetic drift involved the un-accomplishment of random matings and infinite population sizes.
Genetic drift involves:
limited population sizes individuals reproduce by endogamy/exogamy, and matings occur by phenotype.
Economically speaking, which food product would be a "substitute good" for a
beef steak? *
bread
pizza
ostrich
bologna
Which of these statements is TRUE of complementary products?
Economically speaking, a food product that would be a "substitute good" for a beef steak is bologna. Thus, the correct option for this question is D.
What are complementary products?Complementary products may be defined as food or another item that is bought together with the main product. These products are used in conjunction. These products are typically used together with the main product.
A complementary product is produced along with another good. For example, straw is a complement in the production of wheat. The supply of a good increase if the price of one of its complements in production rises. The supply of goods decreases if the price of one of its complements in production falls.
Therefore, economically speaking, a food product that would be a "substitute good" for a beef steak is bologna. Thus, the correct option for this question is D.

pekerja akan selesai dalam 24
hari. Jika Pak Kardi
menginginkan pekerjaan
selesai selama 16 hari,
banyaknya pekerja tambahan
yang diperlukan sekarang
adalah...
Menjawab:
14
Penjelasan:
Dengan 28 pekerja, pekerjaan akan selesai dalam 24 hari
Jika pekerjaan akan selesai dalam 16 hari, jumlah pekerja yang dibutuhkan = x
Asumsikan semua pekerja bekerja pada tingkat yang sama:
Tarif per pekerja:
28 pekerja = 24 hari
1 pekerja = 28 * 24
1 pekerja = 672 hari
Untuk menyelesaikan pekerjaan dalam 16 hari:
672 hari / 16 hari
= 42 pekerja
Pekerja tambahan dibutuhkan:
42 pekerja - 28 pekerja
= 14 pekerja
Oleh karena itu, dibutuhkan 14 pekerja tambahan

How do simple and complex sugars compare in their effect on your glycemic index?
Answer:
The glycemic index allows you to compare the ability of foods to increase blood sugar (glucose) levels. In general, simple carbohydrates have a medium to high glycemic index. In the case of complex carbohydrates, this varies.
Explanation:
The Glycemic Index (GI) is a measure that provides information on how quickly blood sugar levels rise after eating a certain food. Low glycemic index foods are those that have a low content of sugars or simple carbohydrates and that help regulate blood glucose levels, the consumption of foods with a low glycemic index has been proposed as a prevention and / or management factor of obesity, cardiovascular diseases, type 2 diabetes mellitus and some types of cancer. Complex carbohydrates are made up of larger, more complex molecules and are found primarily in the form of starch and fiber. Foods high in fat or fiber are digested more slowly, so they also cause a slower rise in blood sugar. A food with a high GI raises blood sugar faster than foods with a medium or low GI. The GI is higher when foods do not contain fiber and they are easily digested, since they reach the bloodstream quickly, it is also higher if there is sugar or if cooking destroys part of the fiber and favors the digestion of food.

As we discussed, plesiadapiforms were initially interpreted as being the first primates. They were then interpreted as being outside the direct primate lineage because they lacked many of the key traits that define the primate order. This debate continues today. Given what you know about the defining traits found in most living primates, describe four traits you think should be found in the earliest primates. What advantages would these traits have provided the first primates
Answer and Explanation:
Primates must have long, strong fingers capable of supporting their own body weight when they need to climb, the ability to climb trees and stereoscopic vision. These skills help primates not only to survive in the wild, but facilitate the obtaining of food, resistance to predators and reproduction, these characteristics being the most favorable to maintain the continuation of the active species and competitiveness among members of the species.
