(need help asap. thank u so much)
Answers
Answer:
B
Explanation:
water has high specific heat value
Even if the density seems to be altering the effect of temperature, the degree of hydrogen bonding decreases as the temperature rises. Thus, option B is correct.
What role of hydrogen bond to maintain body temperature?The movement of molecules, or their kinetic energy, is measured by temperature. The temperature rises as the motion and energy levels rise.
The body's water plays a crucial role as a thermoregulator, controlling body temperature by assisting in heat dissipation.
When the body becomes too hot, water is lost through sweat, and heat is removed from the body when this sweat evaporates off the skin's surface.
Therefore, The hydrogen bond between water molecules and the amount of heat that must be absorbed to change its temperature by one degree Celsius.

Complete the statement below. A successful way to avoid predation is to not be seen. The adaptation that helps prey not be seen is... A camouflage. B.. mimicry. C.. invisibility.
Answers
Prey animals are often smaller than their predators and have less physical strength, speed and defenses than the predators. Therefore, prey animals have to rely on various adaptive features to avoid being detected by predators. One successful way to avoid predation is to not be seen, and a prominent adaptation that helps prey not be seen is (A) camouflage.
Camouflage is a widespread defense mechanism among animals, wherein an organism blends with the surroundings to remain unseen by predators. There are various forms of camouflage that animals use to avoid being detected by predators. One of the most common forms of camouflage is coloration, wherein an animal has a color or pattern that resembles its environment.
The color of the fur, scales, or feathers of an animal that matches its background help it blend in with its surroundings and avoid being detected by predators. An example of this is the Arctic hare, whose white fur helps it blend in with the snow, making it difficult for predators like foxes to detect it.Another form of camouflage is shape and texture. Many animals have features that resemble the environment they inhabit.
For instance, some insects resemble leaves or twigs, while some fish have markings that make them blend in with their surroundings. An example of this is the stick insect, which looks like a twig, and the chameleon, which can change its color and pattern to blend in with its environment.
In conclusion, camouflage is a crucial adaptation that prey animals use to avoid detection by predators. Through coloration, shape, and texture, animals can blend in with their surroundings, making them invisible to predators and increasing their chances of survival. The correct answer is A.

If variation in a species was only due to meiosis, how would that limit the evolution of that species?
Answers
Meiosis occurs in a diploid sex cell and results in four cells (gametes). All these four haploid/cell gametes are genetically different from each other. The characters of the parent are distributed at random because
These four arms of chromosomes are randomly distributed in the gametesThese arms are novel lengthwise due to the crossing over that has taken place (see fig below). These variations increase further after the union of gametes during fertilization creating offspring with unique characteristics. Thus, it creates a diversity of life and is responsible for evolution.Genetic mutation is the primary basis of fresh genes. Without mutation, you will ultimately run out of different gene pairings, which puts that species in a bit of an evolutionary bind. For a species to survive, it has to maintain genetic variety. Less genetic diversity greatly reduces potential adaptations that might boost reproductive success, which increases the likelihood that the species will become extinct due to disease or competition for food or mates.

Data Table
On the table below, record your observations before and after the interactions and explain how mass was conserved. Describe the changes in properties that prove a chemical reaction occurred. The first row is an example.
Observations Before Interaction Observations After Interaction How was mass conserved? Proof of a Chemical Reaction
Example: Sugar + Heat The sugar is in tiny white particles in a pile. Heat is not seen but is implied by the heat source. The pile of sugar in the pot has a mass of 100 grams. There is a solid, light brown mass at the bottom of the pot. It has a mass of 100 grams. The mass of the sugar is the same in melted form as it is in solid crystal form. There was not a chemical reaction. Sugar did not change composition. It only melted. Melting point is a physical property, and this is a physical change.

Sodium Hydroxide + Copper Sulfate
HELPPPP PLEASEEEEEE
Answers
After Interaction How was mass conserved it is discussed below:
Steel Wool + Oxygen (Fire): chemical change
Egg + Heat: chemical change
Water + Heat: physical change.
Zinc + Hydrogen Chloride: chemical change
Sodium Hydroxide + Copper Sulfate: physical change
What is conservation of mass?According to the rule of conservation of mass, no atoms are lost or created during a chemical process. Instead, the atoms combine in various ways to generate products. This is why the number of atoms in each element in a balanced symbol equation is the same on both sides of the equation.
Steel Wool + Oxygen (Fire):The steel wool is a grayish color and has a rough surface. Oxygen is transparent It looks like a powder, and like if it was rusted steel wool but then broken apart and turned into a powder Well Iron oxide is 7 grams and steel wool combined is 7 grams so that the mass was conserved Yes, this is a chemical change because the steel wool rusted and rust is a chemical change, so iron oxide is cause because if a physical change.
Egg + Heat:The egg has a yellow yolk in the middle while there is some type of liquid at the border of the yolk, but it is clear, the heat is hot but transparent The egg turned into a delicious food called an omelet what was yolk staid as a liquid but got a tad harder, but the transparent border around it turned white It was conserved because the eggshell was 4 grams and the fried egg is 41 grams It is a chemical change because it results in the formation of new particles, and the chemical bonds break up and new ones are formed.
Water (H₂O) + Heat:The water is a clear liquid, while the heat is very hot but transparent The water turned into a type of oxygen -Water Vapor- If 5 g of water becomes a gas it becomes 5 g of water vapor. The mass of the liquid water is simply transferred into the mass of the newly formed water vapor. There was no chemical reaction because the water vapor can be turned back to water also it just changed from a liquid to a gas and did not change its composition. So, it is a physical change.
Zinc (Zn) + Hydrogen Chloride (HCl):Zinc: a white/silver metallic solid. Hydrogen chloride (dilute hydroelectric acid) a transparent, colorless liquid with a very low pH (acidic). Zinc "dissolved" in hydrogen chloride, while emitting a colorless gas. The liquid remains a colorless liquid, possibly still having a low pH from the unused acid. The colorless gas collected in a test tube gives a popping sound when ignited with a burning wooden splint, so it is not air embedded in the zinc, nor dissolved in hydroelectric acid. Well although the zinc chloride is 12 grams and not 15 the gas that was released was 3 grams and as we all know 3 + 12 is 15 so that the mass was conserved The production of a new substance (most probably hydrogen) from the reaction of the two reactants. When a few drops of the liquid product are evaporated on a watch glass, a white residue is left. When a few drops of the liquid hydroelectric acid are evaporated on a watch glass, there is no residue. This proves that a new product (hydrogen gas), (white powder, zinc chloride) is produced instead of zinc being physically dissolved in hydroelectric acid. So, it is a chemical change.
Sodium Hydroxide + Copper Sulfate-Sodium hydroxide is a turbid solution and copper sulfate is in form of bright blue crystals. When their solutions are mixed with each other, a pale blue precipitate of basic copper hydroxide & a solution of neutral salt sodium sulfate will be formed. The sodium hydroxide and the copper sulfate combined make a total of 67 grams and the product is split because the sodium sulfate is 47 grams and the copper hydroxide is 20 grams but all together it is still 67 grams so you could say that the mass was conserved. The proof of the reaction is the appearance of pale blue precipitates of basic copper hydroxide & a solution of neutral salt sodium sulfate. So, it is physical change.

Explain why methicillin resistant Staphlococcus aureus (MRSA) is more prevalent now than it was only 30 years ago. See Section 1.7 (Page) . Methicillin resistance causes an infection to spread more rapidly. Antibiotics cause mutations in Staphlococcus aureus that lead to an increase in the number of methicillin-resistant strains. Frequent and inappropriate use of methicillin-type antibiotics has provided selective pressure that has resulted in an increase in the proportion of methicillin-resistant strains of Staphlococcus aureus. Diseases like AIDS have made people more vulnerable to infections from Staphlococcus aureus.
Answers
Answer: Frequent and inappropriate use of methicillin-type antibiotics has provided selective pressure that has resulted in an increase in the proportion of methicillin-resistant strains of Staphlococcus aureus.
Explanation: The methicillin resistant Staphlococcus aureus is an example of the Theory of Evolution explained by Darwin. He stated that evolution is brought by 3 principles: Variation - the variety of species allows them to adapt better in the environment; Heridity - when those characterists necessary for survival passes on to the next generation; Natural Selection - the organism which is the most adapted to the environment survives to passes on their characteristics;
In a strain of Staphlococcus aureus, there are strains which are resistant to the antibiotics. The constant use of the medicament, and sometimes, the misuse of it, can select those strains which are resistant. As these characteristics are crucial for their survival, they are passed on to the next generation.
This is why the rate of methicillin-resistant Staphlococcus aureus has increased along the years.

What is true about polyploidy and speciation?Select all that apply.A.Both animals and plants regularly form new species through polyploidy.B. It occurs due to environmental pressure.C. It can happen fast.D. Asexual reproduction helps polyploidy lead to speciation.
Answers
Humans have two sets of homologous chromosomes, so humans are usually diploids, but some organisms can have three or more sets of homologous chromosomes, and that is what we call polyploidy.
Polyploid commonly happens due to abnormal cell division, where the chromosomes fail to separate, or it can be caused by chemical substances.
Polyploid is very common in plants, while most animals are diploids and produce haploid gametes. This is because plants have a different life cycle, and also because self-fertilization commonly happens.
In plants, polyploid is responsible for a good percentage of the speciation events, where the new species has a higher ploidy than the original ones. The fact that there are more copies of certain genes can give adaptive advantages, which promotes rapid speciation.
Most of the polyploid species are the result of sexual reproduction, with an even number of chromosomes, however, there are some triploid species that can only reproduce asexually.
This means C, it can happen fast would be the right option.
