Explain how a lack of carbohydrates will impact cellular functions and why?

Answers

Answer:

Carbohydrates they say is the major classes of food and don't forget they are stored by stach in the body and gives your body energy

Carbohydrates are degraded into sugar which, as a primary source, is required for the brain, muscles and other parts of the human body to function normally.

When you don't get enough carbohydrates, the level of sugar in your blood may drop to below the normal range (70-99 mg/dL), causing hypoglycemia.

Atoms with full valence electron shells are chemically stable. Most noble gases have eight valence electrons. So, one model for chemical bonding is the octet rule. This states that atoms will _________ or __________ electrons in order to reach the more stable arrangement of eight electrons in their valence shells. A) lose, gain B) conduct, share C) transfer, share D) conduct, transfer

Answers

Answer:

A - Gain or Lose

Explanation:

Atoms with full valency electron shell are usually very stable. Most noble gases with full valency shell are usually very stable . The valency electron are fully occupied(8) for all noble gases this is what makes them hard to react with other element.

During chemical bonding elements strife to attain the octet rule. The octet rule is to have a full valency electron through bonding . When this atom bond they either transfer electron or share electrons.

The case of transferring electrons forms an ionic bonding. One atom gain electrons while the other lose electrons during ionic bonding. One atom form cation while the other forms anions.

For covalent bonding  atoms are shared to attain the octet rule. This kind of bonding exist between a non metal and another non metals

Answer:

Explanation:A: gain or lose

Which object is hotter in terms of its kinetic energy: the cup of coffee or the iceberg? Explain the reason for your answer in terms of your understanding of the kinetic molecular theory of matter. ​

Answers

Answer:

red-hot iron bar

Explanation:

An iceberg could even contain more heat energy than a cup of coffee or a red-hot iron bar. That's because its bigger and contains so many more molecules, each of which has some heat energy. The coffee and the iron bar are hotter (have a higher temperature), but the iceberg holds more heat because it's bigger.

Which of the following is the observed result of aquatic species exposed to a toxin?

I. Developmental dysfunction
II. Gender imbalances
III. Increased reproduction rates

I, II, and III
I and II
II and III
I only

Answers

The release of toxins such as heavy metals into the water bodies has been deeply frowned at .This is because toxins usually have  a negative effect on aquatic species. The negative effects include:

Developmental dysfunctionGender imbalances

Toxins also gives rise to developmental dysfunction in the animals . The toxins ensures that there is a shortage by interfering/reacting with the nutrient needed for the growth of these organisms.

The issue of gender imbalance is also true as some toxins causes water bodies to be warmer which favors the presence of female  aquatic species such as reef fish.

Toxins causes aquatic bodies to be short of oxygen supply as the elements or compounds released vie for oxygen with the animals which may lead to less reproduction rates and death in severe occasions.

Answers

The purpose of technology is to solve problems and improve various aspects of human life. Option C.

The purpose of technology is multifaceted and encompasses various objectives.

However, at its core, technology is developed to address challenges, solve problems, and enhance different facets of human existence. Whether it is improving efficiency, increasing productivity, advancing communication, or creating innovative solutions, technology aims to provide practical and tangible benefits.

Technological advancements enable us to overcome obstacles and improve the quality of life.

From medical technologies that diagnose and treat diseases to renewable energy sources that combat climate change, technology plays a pivotal role in finding solutions to complex problems. It empowers us to tackle issues in areas such as healthcare, transportation, agriculture, education, and environmental sustainability.

Furthermore, technology drives scientific discoveries and innovation. It provides scientists with tools and methodologies to conduct research, gather data, and analyze information, leading to new insights and understandings of the world.

Technological advancements in fields like computing, artificial intelligence, and genetic engineering have opened up new frontiers for exploration and scientific breakthroughs.

While technology can be used for political advocacy, social mobilization, and improving governance processes, these are additional applications rather than its fundamental purpose.

The primary aim of technology is to address challenges, solve problems, and enhance human experiences in various domains. It serves as a catalyst for progress and development, shaping the way we live, work, communicate, and interact with the world around us. SO Option C is correct.

HELP PLEASE!!!explain how Earth is heated through conduction​

Answers

As it's known conduction needs a medium for heat transfer and during the day, sunlight rays pass through the Earth's atmosphere and near the earth's surface is where most heat transfer by conduction occurs since air is a poor conductor. Thus, the sunlight hits the earth's surface(ground) and in turn heats the air above it and transfering the heat.

It must be known that conduction happens mostly near the earth's surface.

Answer:

Conduction is one of the ways that energy is transferred from the earth's atmosphere to the air. Conduction is the process by which heat energy is transmitted through collisions between neighboring molecules. Think of a frying pan set over an open camp stove.

Explanation:

Imagine you have been shipwrecked and are floating on a small piece of wood in the middle of the ocean. You are terribly thirsty and take a drink of seawater (3.5% salt). What do you think happens to your stomach cells (1% salt), and why?

Answers

Given the higher salinity of the ocean water in comparison to your stomach cells, you will lose water from your cells and become dehydrated.

Osmosis is a phenomenon that shows that in the presence of a space in which the solute concentration is higher than its current location, water will travel towards that more concentrated space in an attempt to dilute the concentration.

The urge to drink is what we call being thirsty. This urge has a biological origin. It is the body's way of telling you that your cells need more water, which leads us to often consume any water we have available. This is not always in our best interest.

However, due to osmosis, drinking the seawater would only have a negative effect on your stomach cells. As stated in the question, the cells contain less concentration of solute (in this case salt) than the water. This means that instead of entering the cell, water would leave to dilute the new seawater, thus dehydrating you more and worsening your condition.
