Jill is preparing to cook a family dinner, and she begins by gathering ingredients for the
main course and dessert. She realizes that most ingredients go through both physical
and chemical changes as they cook.
One of the ingredients for her main course undergoes physical changes. Which of the
following is a physical change?
boiling water
cooking eggs
O grilling hamburgers
O baking bread
Answer:
Boiling water
Explanation:
Boiling water is an example of physical change as it does not cause any change in the chemical composition of water.
What are physical changes?Physical changes are defined as changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to simpler compounds.
Physical changes are always reversible using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible and hence physical changes.
They involve only rearrangement of atoms and are often characterized to be changes which are reversible.

Answer:
It allows the cell to regulate the movement of materials into and out of the cell
Explanation:
This molecule is a saturated fatty acid. The cell membrane is made up of a phosphate head and three fatty acid tails that form a lipid bilayer arrangement.
This lipid bilayer regulates the entry and exit of substances into and out of the cell. Small non-polar molecules, like oxygen and carbon dioxide, are soluble in the lipid bilayer and can easily cross the plasma membrane. Small uncharged polar molecules, like water, can pass through the membrane by osmosis. Larger molecules such as glucose, or charged molecules like ions, require active transport to be passed across the cell membrane.

What are the differences encountered in the photosynthetic-respiratory pathway of the carbon cycle, as it exists on land and in the ocean?
In a marine environment, the role of plants is performed by _______(phytoplankton, zooplankton, microorganisms) and an additional flux of carbon into the oceans is through _______(aeration, diffusion, deposition).
Answer:
phytoplankton; diffusion
Explanation:
"Phytoplankton" takes the role of the plant in the marine environment because it consists of tiny plants that contain chlorophyll–just like the terrestrial plants. This provides food to many aquatic animals in the ocean.
When it comes to carbon cycle, carbon dioxide from the atmosphere is being diffused into the ocean by dissolving it. The carbon in the ocean turns into an organic matter through the process of photosynthesis. The ocean is said to have more carbon compared to the atmosphere because many marine animals use it for survival.

Fungus is an organism not drawn in the above food chain although it has a very important role. Describe an important role of organisms such as fungi and bacteria can you help me plz!!!
Answer:
Explanation:
Fungi and bacteria are decomposers. This means they help breakdown dead plant and animal matter.
This is kind of a baseline descripiton but i hope it helps!
Two of the most crucial creatures in an ecosystem are fungi and bacteria. They are essential for the nutrition cycle, the breakdown of organic matter, and the generation of food for other species. In order for other creatures to exploit the complex organic compounds, fungi and bacteria convert them into simpler forms.
What is the way to the food chain ?For instance, when dead plants and animals are broken down by fungi and bacteria, vital nutrients like nitrogen, phosphorous, and sulphur are released into the soil. Following the uptake of these nutrients by plants, food is produced that is then devoured by other species in the food chain.
Additionally, bacteria and fungi collaborate with other living things like plants in symbiotic interactions. For instance, several fungi collaborate with plant roots to provide the providing the plant with nutrients it needs in exchange for carbs.
Mycorrhizal symbiosis is the name for this kind of partnership, which is necessary for the development and well-being of plants. Since many bacteria and fungi produce chemicals that can stop the formation of dangerous infections, they also play a significant part in disease prevention.
Finally, fungus and bacteria are significant food sources for many organisms. For example, fungi like mushrooms and others feed animals like deer, birds, and other fauna.

which would a scientist most likely examine to locate gene mutations?
Answer:
Single base pair mutations can be identified by any of the following methods: Direct sequencing, which involves identifying each individual base pair, in sequence, and comparing the sequence to that of the normal gene.
DNA is the molecule which is most likely to be examined to locate gene mutations. Thus, the correct option is A.
What are Gene mutations?Genetic mutations are the changes to the DNA sequence which happen during the process of cellular division when the cells make copies of the DNA molecules. The DNA molecule tells body how to form and function well.
Genetic mutations are the changes which could lead to genetic conditions such as cancer, or they could help the humans to better adapt to their environmental conditions over a period of time.
Mutations can be of many different types, such as substitution, deletion, insertion, and translocation of the genetic sequence.

They result without the fusion of gametes.
(Choice B)
B
They vary genetically from the parent.
(Choice C)
C
They contain half of the genetic information of the parent.
(Choice D)
D
They develop very slowly compared to offspring of sexual reproduction.
Answer: the answer is A “They result without the fusion of gametes”
Explanation:
The statement that correctly describes the offsprings of asexual reproduction is: they result without the fusion of gametes.
ASEXUAL REPRODUCTION:Asexual reproduction is a type of reproduction that involves a single parent organism. The single parent cell gives rise to two new daughter cells by undergoing division. As a result, the new organisms are genetically identical to one another, hence, genetic diversity is not ensured. On the other hand, sexual reproduction involves the fusion of gametes to produce genetically different organisms.Learn more about asexual reproduction at: https://brainly.com/question/4100787?referrer=searchResults

termites are insects that feed on wood, which contains cellucose. scientist have observed that some termite species prefer wood that has been attacked by fungi. Construct an explanation for this observation
Answer:
In this observation, the termites and the fungi rely on each other in order for survival. In other words, they have a symbiotic relationship. This type of fungi helps the termites by digesting cellulose from the wood since termites are unable to digest it. In turn, the termites provide the fungi an environment where they can be cultivated. This explains why termites prefer a wood that was inhabited by fungi.
