Max tried an experiment in which he added red-dyed salt water to clear freshwater. He noticed that a lot of the red water sank below the clear water. Which of the following statements explains why this happened?
a. Adding salt to water makes it more dense.
b. Adding salt to water makes it less dense.
c. Adding salt to water decreases its temperature.
d. Adding salt to water increases its temperature
Answer:
A
Explanation:
Adding salt to water causes its density to increase. Denser water will sink below less dense water.
As salt water is denser and will sink at the bottom and adding the salt raises the temperature of water body and hence will make it more warm and saline.
A max tries to add red dyed salt water to clear the fresh water he sees a red color sinking below the fresh water that is cool.The option D is correct.

**Urgent** Will mark brainliest!
Answer:
Although these two animals are both bears, clearly they are entirely different. Becasue they live in pretty much opposite environments, they developed individual traits so they could survive, which is called adaption. While the polar bear's thick fur and fat serve as great protection against the cold, it wouldn't be very helpful in hot climates. And the sun bear, with it's short hair and lack of protection, would freeze to death in the polar bear's environment. Each animal, over time, has to develop new traits that allow it to adapt to it's particular environment.
Answer:
These 2 different types of polar bears, may be the same type of animal, but as given in that text, they differ. These 2 different types of polar bears have different types of survival skills, in order to adapt to their environment. The Polar bear in the Northern Hemisphere has very thick fur, and other thick parts in it's body to keep them warm in the ice-covered areas that it lives in so that it wont die, due to the cold. While on the contrary, the bear in the tropical rainforest only has short hair, to keep them at a just-right temperature, so it wont die due to how hot it is. If both of these bears were to switch their environment, then they will die easily since they are not well adapted to that environment.

If i added 27 grams of salt to water and saparated the solution with a hot plate what amount of salt will be left behind
Answer:
27 grams
Explanation:
27 grams of salt would still be left behind.
The dissolution of salt in water is a physical reaction and the salt can be recovered by evaporating off the water using appropriate procedures.
Provided that no part of the salt/water mixture is lost during the process of evaporation, if 27 grams of salt was dissolved initially, the same amount of salt would be recovered at the end of the separation process.

Identify and describe the three ways the mutations affect organisms
Answer:
they may cause the development of a disease-causing allele
they may cause the development of a more beneficial allele
they, in some cases, may have no noticeable affect.
Explanation:
Answer:
Mutations may be beneficial, harmful, or neutral to organisms. If the change caused by a mutation is useful to the organism, then it is beneficial. If the change is damaging to an organism, then it is harmful. If the change is neither useful nor damaging, then the mutation is neutral.
Explanation:
What primary method does the cell employ to ensure gene expression only occurs when necessary?
Limited amounts of specific DNA
Phosphorylation cascade with multiple steps
Receptors that only fit specific hormones
Unique transcription factors made of carbohydrates
Answer:
Unique transcription factors made of carbohydrates
Explanation:
Gene expression refers to the way by which the genes which contain hereditary materials in the cells are converted to certain proteins. Gene expression is regulated to avoid the wastage of useful energy. Transcription allows the copying of genetic information from the DNA to the RNA.
Transcription factors can activate or deactivate a gene thus hindering its expression. Unique transcription factors help to regulate gene expression.
Answer: receptors that only fit specific hormones

Describe three other features of a bacterial cell.
Answer:
hope it helped
Explanation:
Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.
The features of a bacterial cell are the following:
Bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.
They are essential in the decomposition processes of organic matter, necessary for the recycling of elements such as carbon or nitrogen.
They reproduce quickly and by asexual procedures, which consist of the replication of the progenitor cell in two exactly equal to it (binary fission).They are made up of a single cell without a cell nucleus, but with a nucleoid (an irregular region where the circular DNA of prokaryotes is found).They have a peptidoglycan cell wall that covers the cell outside the plasma membrane.Scattered throughout the bacterial cytoplasm are ribosomes (in which protein synthesis takes place) and there are also often plasmids (small non-chromosomal DNA molecules).Some bacterial cell also have capsules, a rigid protective structure that is outside the cell wall and flagella to move (if they are mobile).Therefore, we can conclude that bacteria are a large group of prokaryotic microorganisms (devoid of cell nuclei) of various possible shapes and sizes.

How do animals get nitrogen that is stored in the soil?
O A) Animals do not take in the nitrogen stored in the soil.
O B) Bacteria change the nitrogen into a gas that the animals breathe.
OC) Plants ab orb the nitrogen from the soil and animals can eat the plants.
O D) The animals can eat the soil and absorb the nitrogen through their digestive system
Answer: C) Plants absorb the nitrogen from the soil and animals can eat the plants.
Heterotrophs, specifically herbivores and omnivores, are animals that eat plants (autotrophs) to get the nutrients they need. Those that eat the plants get the nitrogen from the plant that has absorbed it from the soil. Omnivores and carnivores eat the herbivores to get nitrogen that way. For more more information, take a look at the nitrogen cycle.
Read the information below. You just scratched a mineral sample with your fingernail. Your fingernail measures 2.5 on the Mohs scale and fluorite measures 4 on the Mohs scale. Explain why the mineral sample you have cannot be a piece of fluorite
Please help me I need to write a 3 sentence
Answer:
It can't be fluorite because your fingernail is less on the Mohs scale than fluorite. When an object is less than another object on the Mohs scale it doesn't leave a scratch on the other object. Therefore if your finger leaves a scratch on the material then it has to be less than 2.5 on the Mohs scale. Fluorrite is not less than 2.5 on the Mohs scale so it is impossible that it is that mineral.

Based on what you learned about how plants function, why do you think they produce less fruit in the winter?
Frost is capable of damaging the flower buds and blooms of fruiting plants to the extent that the plants will not bear fruit.
Answer:
A reason why your plants might be under-producing is the weather. Unusually hot, cold, dry, or wet conditions can interfere with fruit production. Wind and heat can dry out soil and scorch plants.
