Answer:
1. True
- Those are compounds
2. False
-They are actually polar molecules
3. True
-Acids are molecules that give away a type of subatomic particle
4. False
-While they are usually the same, it is not necessary to have equal protons and neutrons. However, the ratio of electrons to protons is always equal. An extra proton in an atom makes a new element and an extra neutron creates an isotope.
5. False
-An isotope is an atom that has gained an extra neutron.
6. True
-Oxygen is more electronegative than most of the halogen elements.
7. True
-Cellulose and starch are both polymers made from a glucose monomer.
8. True
-During DNA replication both strands that make up the double helix are used as a template that new strands copy.
9. True?
- I think the question is referring to a codon/nucleotide triplet, because each base cant specify a single amino acid and nucleotide triplets are made up of three nucleotide bases so id say true.
10. True
-Side chain groups vary in size, shape, charge, hydrophobicity, and reactivity, which makes them unique.
I need help with modeling a carbon cycle, do you mind helping me? :)
Will mark brainliest :D
Explanation:
The Carbon Cycle
The element carbon is a part of seawater, the atmosphere, rocks such as limestone and coal, soils, as well as all living things. On our dynamic planet, carbon is able to move from one of these realms to another as a part of the carbon cycle.
Carbon moves from the atmosphere to plants. In the atmosphere, carbon is attached to oxygen in a gas called carbon dioxide (CO2). Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth.
Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.
Carbon moves from plants and animals to soils. When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years.
Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.
Carbon moves from fossil fuels to the atmosphere when fuels are burned. When humans burn fossil fuels to power factories, power plants, cars and trucks, most of the carbon quickly enters the atmosphere as carbon dioxide gas. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. Most of the remainder becomes dissolved in seawater.
Carbon moves from the atmosphere to the oceans. The oceans, and other bodies of water, absorb some carbon from the atmosphere. The carbon is dissolved into the water.
Carbon dioxide is a greenhouse gas and traps heat in the atmosphere. Without it and other greenhouse gases, Earth would be a frozen world. But since the start of the Industrial Revolution about 150 years ago humans have burned so much fuel and released so much carbon dioxide into the air that global climate has risen over one degree Fahrenheit. The atmosphere has not held this much carbon for at least 420,000 years according to data from ice cores. The recent increase in amounts of greenhouse gases such as carbon dioxide is having a significant impact on the warming of our planet.
Carbon moves through our planet over longer time scales as well. For example, over millions of years weathering of rocks on land can add carbon to surface water which eventually runs off to the ocean. Over long time scales, carbon is removed from seawater when the shells and bones of marine animals and plankton collect on the sea floor. These shells and bones are made of limestone, which contains carbon. When they are deposited on the sea floor, carbon is stored from the rest of the carbon cycle for some amount of time. The amount of limestone deposited in the ocean depends somewhat on the amount of warm, tropical, shallow oceans on the planet because this is where prolific limestone-producing organisms such as corals live. The carbon can be released back to the atmosphere if the limestone melts or is metamorphosed in a subduction zone.
how can we prove that the oxygen in glucose comes from co2?
what would you do?
What would your hypothesis be?
what results would you expect to obtain and why?
Answer:
6CO2 + 6H2O → C6H12O6 + 6O2.
This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.
Explanation:
There’s a saying in brain science based on the work of Donald Hebb: neurons that fire together, wire together. The more they fire together, the more they wire together. In essence, you develop psychological resources by having sustained and repeated experiences of them that are turned into durable changes in your brain. You become more grateful, confident, or determined by repeatedly installing experiences of gratitude, confidence, or determination. Similarly, you center yourself increasingly in the Responsive, green zone – with an underlying sense of peace, contentment, and love – by having and internalizing many experiences of safety, satisfaction, and connection.

Answer:
they are the basis of decay and decomposition, which helps waste disintegrate. it`s the only reason earth isnt overrun with biodegradable waste
they enhance soil fertility. ever seen farmer put manure in fertilizer? its bc the bacteria helps plants grow
specific bacterias are used in medicines. there are good and bad kinds, and we use the good kinds to fight bad ones off (antibiotics)
the bacteria in our bodies helps break down the food we digest so that we can absorb the nutrients and excrete waste to keep our bodies healthy
other bodily bacteria can fight off diseases, viruses, etc. this could summarized into the immune system

The image shows a vulture soaring over a rocky cliff. The arrows model the different ways energy moves between the sun, atmosphere, and geosphere.
Match each type of energy transfer to the arrows shown in the image. Describe how energy transfer helps the vulture soar above this rocky cliff.
Given what we know about the way energy moves through the Earth, we can confirm that the vulture uses the hot air currents that result from this movement of energy to soar above the cliff.
The energy from the sun travels through the atmosphere, then into the soil where it is absorbed. The soil then radiates the heat back out into the atmosphere.
Given that hot air rises, this radiated heat causes the formation of hot air currents that the vulture then uses to glide upwards in a circular motion.
The vulture planes over the hot air currents with its wings at an angle to climb, it goes higher the further it wishes to travel given that once at the desired height, it glides downward towards its destination.

During a chemical reaction, the number of atoms
A stays the same
B increases
C decreases
D fluctuates
During a chemical reaction, the number of atoms stays the same
Atoms of elements are involved in chemical reactions. Atoms of different elements combine together to form molecules or compounds. According to the law of conservation of mass, matter cannot be created nor destroyed. This means that the number of atoms (matter) in the reaction does not increase or decrease but rather, stay the same.Atoms only get rearranged as they form new molecules and compounds, they however, do not change during chemical reactions.
Hence, atoms stay the same during chemical reactions.

You observe the growth of a group of plants that have been tipped over.
How will auxin influence cell growth in the roots of these plants?
Auxin will build up on the lower side of the root and inhibit cell growth.
Auxin will build up on the lower side of the root and stimulate cell growth.
Auxin will build up on the upper side of the root and inhibit cell growth.
Auxin will build up on the upper side of the root and stimulate cell growth.
Auxin is responsible for the growth of cells in the roots of plants. Auxin build up on the lower side of the root which inhibit the cell growth. Auxins have an inhibitory effect on primary root growth. Thus, the correct option is A.
What is Auxin?Auxin is a plant growth hormone, which promotes cell growth and elongation of the plant. In cell elongation, auxin alters the plant wall plasticity making it easier for the plant to grow upwards. Auxin also influences the rooting in the plant.
Auxins have an impact on the growth of roots. Auxins facilitate the initiation of roots in plants. These hormones induce both growth of root branching (root initiation) and roots that are pre-existing. They also play important role in the formation of the adventitious root.
Therefore, the correct option is A.
