An ionic bond is most likely to form between:
a)
a negatively and a positively charged ion.
c)
two uncharged atoms.
b)
two positively charged ions.
d)
two negatively charged ions.

Option D is correct.

d. have the same movement as thermohaline currents

The movement of the surface water of the ocean due to the certain pattern of wind and Coriolis Effect and earth spin creates surface currents. That are influenced by all of the above three except the fourth one.

Option D is correct.

d. triangle

Water molecules are not linear in shape. Oxygen has 8 electrons in its valence shell so there are two bonding pairs in water and two lone pairs. Lone pairs strongly repel each and water molecules get bent shape due to this.

Option C is correct.

c. oceans

We just do not know that how much heat is captured in the oceans. Most of the heat dissipates in the atmosphere is absorbed in the oceans. So, most of the heat is retained in oceans.

Option B is correct.

b. in the equatorial region

Hurricanes begin as the warms storms in tropical regions of due to the warm moist water of Atlantic and Pacific Oceans near the equator. So the correct option is B.

The odd statement is b. exist in large lakes

Surface currents are generated largely by wind. Their patterns are determined by wind direction,Earth's rotation, and the position of landforms that interact with them. Currents may also be generated by density differences in water masses caused by temperature and salinity variations but they are not present in the form of lakes

The shape of H2O molecule is oval

It is not completely oval but irregular A molecule of water has an angular or bent shape. The H-O-H bond angle in a molecule of water is 104.5o, an angle that is also quite close to the 109.5o bond angles of methane so we can say that it is a little bit oval plus triangular too.

Much of the earth's heat is retained in the oceans

Earth retains its temperature in water cycle and we know that water cycle is mostly dependent upon the ocean. Although winds are also responsible but mostly it is retained by oceans. Similarly the constant exchange of energy between the Earth's surface and the greenhouse gases is what enables the planet to maintain its average temperature of 15 degrees Celsius.

Most hurricanes will originate in the equatorial region

A hurricane needs the warm water of the tropics, which feeds a storm with energy, in order to form. Most of them are originated in the African continent and that is why we can say  that they originate from the equatorial region because much part of Africa lies in equator.

The right answer is D. modifying, sorting, and packaging proteins prior to transport.

The Golgi apparatus is one of the organelles necessary for the production of functional proteins.

Answer: a. potential energy in chemical form

Explanation:

The food is the source of chemical energy as there exists various chemicals in the food like proteins, fats, vitamins, carbohydrates and others. The chemical energy is converted into potential energy after the digestion of food. The potential energy is in the form of ATP (Adenosine triphosphate) which is released and stored when the chemical bonds present in the food breaks down.  

Answer:

In plants only: May produce seeds, can photosynthesize

In fungi only: heterotrophic, may have aseptate hyphae

In Both: can absorb nutrients from the soil, may have rhizomes, have cell walls

Explanation:

Plants are unicellular organism that reproduces using seeds as it performes sexual mode of reproduction. Plants are autotrophic in nature and make food using sunlight, carbon dioxide and water

The fungi absorbs nutrition from the other organism and performs heterotrophic mode of nutrition and have aseptate hyphae.

Plants and fungi both absorbs the nutrients from soil and contain cell wall. The cell wall of plants is made of cellulose and in fungi it is made of chitin.

Answer:

Culture establishes the framework in which individuls judge their environment.

Explanation:

Quality of life is the concept sorrounding all aspects of a persons life and focus on that person's needs as well as the way they are satisfied in its environment. But there is a bias in it, because while a person living in a country that offers it a lower standard of living can perceive it has the best quality of life without universal healthcare, free access to education, and a big market of employment. That person can believe that it has the best quality of life. Even though are countries with better standard of living. So, quality of life is a subjective cultural construction built by a society perception. That becomes objective and universal when is compared to different countries.

Mistakes in DNA replication can lead to mutations, which are a mechanism of evolutionary change. DNA replication is highly accurate, but when errors occur and are not corrected, they can result in a change in the amino acid sequence and be inherited if present in germ cells.

Among the options provided regarding DNA replication, the true statement is that mistakes in DNA replication are a mechanism of evolutionary change. DNA replication is a highly accurate process, however, errors during replication do occur, albeit infrequently (approximately once for every 10 billion nucleotides). Although many mistakes are corrected by repair mechanisms, some uncorrected errors lead to mutations. These mutations can be passed on to offspring if they occur in germ cells, such as sperm or eggs, and they can result in a change in the amino acid sequence of proteins. This process is one of the drivers of evolutionary change, allowing populations to adapt over time to new environments and conditions.

Your answer is C if its asking for trace in the human body and if its asking for normal trace such as (DNA) it would be A .

Brainiest Please?

The option C is correct. Iron is a trace element.

Trace elements are elements which are required in small amounts but they are essential to the body.

Carbon and hydrogen are needed in abundant amount because it is present in all organic compounds like sugars, and lipids.

Nitrogen is part of amino acids, building blocks of proteins.

Iron is essential only for some enzymes and hemoglobin. And it can also be recycled in the body.

The answer should be positively because eating is good....if not I'm super sorry. its a 50/50 chance lol

Answer:

The food pyramid is an example of science positively influencing society.

Explanation:

We consider something as a positive influence, when it results in improvements for society and citizens as a whole. In this case, we can say that the food pyramid is an example of science that positively influences society. This is because the food pyramid informs how people should eat healthily, without excesses and supplying all the needs of their body, leaving the population more healthy and nourished.

convolutions

explanation

The convolutions is basically  consist of grooves called sulci and raised ridges in between called gyri . A convolution is a curvature of a surface. Picture a fully inflated beach ball. It has no convolutions - it is entirely convex. Now, take out some of the air, and fold the surface of the ball. Each place you make a valley in the surface, you make a convolution

The answer is Convolutions

Convolutions are located in the cerebral cortex area of the brain. This area has a wrinkled surface , hence named as Convoluted part or convolution. Convolutions contain ridges and grooves. Deep portions or grooves are called sulci Whereas raised portions or ridges are called gyri. Basically gyri are the specific area of the brain where memories are stored.

The correct answer is - waves.

When there's an earthquake, it means that there's a big shock deep inside the ground where a large amount of energy is released, This energy, since it is inside of the Earth, is transferred through the crust in the shape of waves, or rather, seismic waves. The bigger the stress inside the Earth, the more intense the seismic waves, and vice versa, the lesser the stress, the lesser the intensity of the waves. There's special scales that are measuring the frequencies of this waves, and some of the most popular in usage are the Richter scale, and the Mercalli scale.

As we know before in back in time. Animals will adapt to their environment that their ancestors didn't have. This animal must have used to have a straight legs but then adapted since it couldn't really move. Then over time it most have started to bend so that way it could move faster. I think that it must have had straight legs because most animals aren't originally the same like humans have tailbones and tails or six fingers. I also feel that it was a analogous structure. Because the squirrel and vertebrate fossil had the similar appearance but are not evolved together and don't have a common ancestor.

Locard's exchange principle refers to option D) the transfer of evidence when two objects come into contact, which is a fundamental concept in forensic science used to link suspects to crime scenes.

The correct answer to the student's question regarding Locard's exchange principle is option D) There is a transfer of evidence when two objects come into contact with each other. This principle is a cornerstone of forensic science and underlines the importance of trace evidence at a crime scene. It postulates that whenever two objects interact, there is always an exchange of material between them. This can include DNA, fibers, hair, soil, or residues that can be used to link a suspect to a crime.

The principle can be likened to basic concepts in chemistry and physics, where interactions between particles are observed and measured to build theories about the properties that cannot be directly observed. Likewise, the interactions at a crime scene are detailed through the evidence picked up and the transfer of particles as suggested by the principle. It's an intuitive concept that reinforces the idea that the perpetrator of a crime will both bring something into the crime scene and leave with something from it. This principle is essential in the analysis and linking of suspects to crime scenes.

The nucleus is the cell's control center, housing the genetic instructions. Enclosed by a nuclear envelope, it regulates transport of material into and out of the nucleus. However, not all cells contain a nucleus.

The nucleus is a crucial component of a cell, often considered its control center because it houses the cell's genetic instructions or DNA. This genetic material determines the entire structure and function of the cell.

The nucleus is enclosed by a double membrane known as the nuclear envelope that assists in regulating the transport of materials, like ions and molecules, in and out of the nucleus through nuclear pores. Inside the nucleus, the semi-solid fluid is known as nucleoplasm, where we find the chromatin and the nucleolus.

Interesting to note, not all cells contain a nucleus. Some cells, such as mammalian red blood cells, do not contain nuclei. In contrast, muscle cells might contain more than one nucleus, a condition known as multinucleated.
