The scientist is studying cohesion, a property of water that makes water molecules attract to one another.
Answer:
Cohesion
Explanation:
Cohesion refers to one of the properties of water molecules to get attracted to each other. Since each water molecule an oxygen atom with a partial negative charge and hydrogen atoms with a partial positive charge, water molecules form intermolecular hydrogen bonds. This leads to the tendency of water molecules to stick together, that is, cohesion.

Which of the following is a requirement for exponential growth of a population?
A. There are no limiting factors. B. There's competition from other organisms. C. There's a finite number of resources. D. The population is in a climax community.
Answer:
A
Explanation:
hope this helps
Answer:
A.There are no limiting factors
Explanation:
Exponential growth is the population growth in which the size or number of individuals is increased by a constant multiple rate in each generation. When there are no limiting factors such as when resources availability is unlimited in a habitat, the population grows by increasingly higher amounts in an exponential fashion. A good example of exponential growth can be observed when bacteria is grown/reproduced by binary fission in the laboratory.
Describe an environmental factor that could influence natural selection and decrease genetic diversity
Answer:
Availability of sunlight.
Explanation:
Some living organisms need a lot of sunlight to survive and cannot stand living in the shade, as is the case with some plants. In this case, the availability of sunlight presents itself as an environmental factor that will influence natural selection, because with less availability of sunlight, the less adapted organisms will die and the more adapted organisms will resist and pass this trait to their descendants.
Natural selection tends to decrease genetic variability because only a few genotypes will be selected. In addition, it also contributes to the permanence of a certain characteristic in the population.
The process of being selected by the nature to survive in the current condition is called natural selection. Only those species can be naturally selected who are ready to change and adapt themselves according to environmental needs.
These are the factors that support natural selection.
ReproductionRecombinationCrossing overMutationMany species are not able to mate with the other species due to geographical barriers and also not being able to migrate to other habitats.
For example- Australia is separated from the other continents, the marsupials are only restricted to the specific landmass and are not able to mate with other animals from other countries.
Increases in temperature harm cold-blooded animals. They can not able to maintain the normal body temperature and lead to the death
Therefore, The factors which affect natural selection are geographical barriers and a rise in temperature.

How does ATP release energy that's stored within the molecule?
A. Altering number of carbon groups tied to the phosphate backbone B. Altering the total amount of kinetic energy within ATP C. Altering the number of oxygen groups revolving around the central molecule D. Altering number of phosphate groups tied to the carbon backbone
Answer:
Option (D).
Explanation:
ATP (adenotriphosphate) molecules are considered as energy currency of the cells as molecules provide energy for various cellular functions.
The energy is stored in ATPs in two high-energy phosphate bonds, known as phosphoanhydride bonds. This stored energy is released in during hydrolysis of ATP, which involves removal of terminal phosphate groups bound the carbon backbone.
Thus, the correct answer is option (D).
Answer: Option D
Explanation: Adenosine triphosphate are known as the high energy molecules of the cells which provides energy to all the living organism.
The energy is stored in the phosphate bonds of this molecule. These bonds are known as phosphoanhydride bond.
As soon as the hydrolysis of this molecule takes place the energy from the bonds is released.
The cleavage of terminal phosphate from the carbon backbone takes place to generate energy.
What type of invertebrate are robber crabs? Why do these crabs fit in this category?
The are arthropods. They are arthropods because they undergo ecdysis, have segmented bodies and the key trait of jointed limbs “arthro”=jointed and “pod”=foot
Robber crabs are arthropods that are considered so because, as adults, they have a thick exoskeleton inside their shell.
What are Invertebrates?Invertebrates are defined as the paraphyletic group of animals which neither possess nor develop a vertebral column derived from the notochord. It includes all animals other than the chordate subphylum Vertebrata.
They range in size from microscopic mites and nearly invisible flies to giant squids with soccer-ball-sized eyes, which are by far the largest group in the animal kingdom, accounting for 97 percent of all animals. These group includes spiders, worms, snails, lobsters, crabs and insects like butterflies.
Robber crabs have jointed legs like all arthropods, which is why they fall into this category.
Thus, Robber crabs are arthropods that are considered so because, as adults, they have a thick exoskeleton inside their shell.

How does heat capacity affect temperature change?
Yes, the specific heat capacity of substances change when there is a change in temperature. At molecular level, the internal energy of a substance is stored in form of translational, rotational and vibrational energy. It has 3 degrees of freedom for each form of energy. In lower temperature ranges, say below 1000 degree celsius, vibrational energy is insignificant.
If a reaction equation is balanced, then___.
Select all that apply.
A. it will follow the law of conservation of mass
B. There will be coefficients written in front of the formulas
C. The mass of products will be equal to the mass of the reactants
D. The mass of the products will be greater than the mass of the reactants.
If a reaction equation is balanced, it will adhere to the law of conservation of mass, showing equal mass for reactants and products, and balanced with coefficients in front of the chemical formulas. The correct option is A.
If a reaction equation is balanced, then several things hold true based on the principles of chemistry. Firstly, it will follow the law of conservation of mass. This fundamental law states that mass cannot be created or destroyed in a chemical reaction. Consequently, the total mass of the reactants must equal the total mass of the products. Secondly, you will find coefficients written in front of the formulas to indicate the relative amounts of each substance necessary to balance the equation.
Subsequently, the mass of the products will be equal to the mass of the reactants. This is a direct consequence of balancing the equation. It's not correct that the mass of the products will be greater than the mass of the reactants, as this would violate the law of conservation of mass.

Elements such as nitrogen, carbon, and oxygen cannot be made or destroyed; they can only change their location by cycling through the biosphere.
true or false?
Answer:
true
Explanation:
Answer:
True
Explanation:
The gases such as nitrogen, carbon, oxygen are present in a certain amount in the atmosphere. This amount is always constant due to the gaseous cycle in our ecosystem. The gaseous cycle is coming under the biogeochemical cycle. Unlike energy and water, these gases go to the atmosphere and then come to the biosphere in a cyclic manner. This gaseous cycle includes the nitrogen cycle, oxygen cycle, and carbon dioxide cycle. This gaseous cycle justifies the given statement.

liver decreases its protein synthesis and no longer breaks down aldosterone effectively
Answer:
This statement is true
Explanation:
The liver breaks down many hormones once they have done their work in the body. These hormones are called steroid hormones. One of these hormones is aldosterone that controls the balance of sodium, potassium, minerals, and water in our body.
If the liver decreases its protein synthesis, it will not be able to break down aldosterone. These hormones accumulate in the body and can cause an imbalance of many nutrients in the body.

How can the environment affect population size?
please help!!!! it's about animals in the wildlife
If the environment gets polluted or treated poorly, than there will be less animals. If the environment grows a bunch of grass however, there will be more animals eating the grass which increases the population. But if they run out of grass, then the animals die.
Answer:
The environment can affect the population size by different factors. Some examples are climate, food, space, etc. If the environment lacks any of these, the population will decrease since it will not have the necessary survival needs.

the two proteins that cause muscle cells to contract are
Answer:
Myosin and Actin.
Explanation:
The two proteins myosin and actin work together to help the muscle cells relax and contract. The two proteins need each other and together they are called actomyosin. I hope this is what you were looking for and if not I'm sorry.
The two proteins that cause muscle cells to contract are actin and myosin. These proteins interlock and slide past each other in a process powered by ATP and regulated by calcium ions, troponin, and tropomyosin, which collectively result in muscle contraction.
Proteins Involved in Muscle Contraction
During muscle contraction, the myosin heads form cross-bridges by attaching to the actin filaments in the presence of calcium ions (Ca++). This process is further regulated by other proteins such as troponin and tropomyosin, which prevent myosin from binding to actin when the muscle is at rest. The release of Ca++ from the sarcoplasmic reticulum upon nervous stimulation leads to the binding of calcium to troponin, causing a change in the shape of troponin and a subsequent shift in tropomyosin position. This exposes the myosin-binding sites on actin and permits the myosin heads to bind to actin and perform a power stroke powered by the hydrolysis of adenosine triphosphate (ATP). It is the sliding of these filaments past each other, known as the sliding filament model of muscle contraction, that results in muscle shortening and generating force.
Muscle tissue is made up of cells that contract and release to produce movement. Which process provides the energy that the cells need to contract?
Cell respiration is the process

Elizabeth is getting ready to run a marathon. She's hoping that the ATP in her body is good for long-term energy storage for the race. Why is her thinking incorrect?
A. ATP doesn't release energy fast enough to support running
B. ATP takes too long to transfer oxygen from the lungs to the legs
C. ATP is an unstable molecule
D. Running requires only potential energy to work muscles
Answer: A. ATP doesn't release energy fast enough to support running.
Explanation:
Elizabeth's thinking is incorrect because ATP doesn't release energy fast enough to support running. Running a marathon requires both immediate energy from ATP and sustained energy from glycogen.
Explanation:Elizabeth's thinking is incorrect because
ATP doesn't release energy fast enough to support running. ATP is the immediate source of energy for muscle contraction, but it can only supply energy for a few seconds of intense activity. For long-distance running, muscles rely on other energy sources such as glycogen. Glycogen is stored in the muscles and liver and can be rapidly broken down into glucose, which is then converted into ATP through cellular respiration. However, this process still requires oxygen, which is delivered through the heart and lungs. Running a marathon requires both immediate energy from ATP and sustained energy from glycogen, making Elizabeth's thinking incorrect.
