Answer:
Regulates which materials enter and leave the cell.
Explanation:
I'm not 100% sure on this but I think cell membranes provide protection for the cell as well as regulating what enters and leaves the cell.
Cell membrane regulates which materials enter and leave the cell. So, the correct option is (D).
What is Cell membrane?Cell membrane is also called plasma membrane which is a semipermeable membrane made of lipids and proteins and found in all types of cells in humans, animals, plants, bacteria etc.
The cell membrane is the outermost boundary of animal cells. Cell membrane has many functions which are as follows:
Maintaining integrity within the cell.Providing support and preserving the shape of the cell.Through balancing endocytosis and exocytosis, it aids in cell growth regulation.Cell signaling and communication are also facilitated by cell membranes.Cell membrane functions as a selectively permeable membrane which enable only certain chemicals to enter the cell.
Thus, cell membrane regulates which materials enter and leave the cell. So, the correct option is (D).

A unicellular organism has how many cells?
Answer:
A unicellular organism has one cell.
Explanation:
A unicellular organism consists of one cell.
The prefix 'uni - ' means one.
A multicellular organism has multiple cells ('multi -').
Hope this helps.
A unicellular organism has only one cell. Unicellular organisms are composed of a single cell that carries out all the functions necessary for their survival.
Unlike multicellular organisms, which are made up of multiple cells organized into tissues, organs, and systems, unicellular organisms are complete and self-sufficient on their own. They are considered the simplest form of life.
The single cell of a unicellular organism contains all the structures and organelles required for essential life processes such as metabolism, reproduction, and response to stimuli. This includes the cell membrane, cytoplasm, genetic material (DNA or RNA), and various organelles like mitochondria, ribosomes, and nucleus (if present). The unicellular organism carries out all its life functions within this single cell.
Examples of unicellular organisms include bacteria, archaea, protozoa, and some types of algae. These organisms can live independently and carry out all necessary functions within their single cell. They can reproduce through cell division, where the parent cell divides into two identical daughter cells.
Overall, the characteristic feature of a unicellular organism is its simplicity, consisting of a single cell that encompasses all the structures and processes required for life.

I need a sentence describing how volcanoes are created around the Ring of Fire. Using
all of these terms: convection current, subduction zone, plate boundary, oceanic plate, water, magma, and volcano.
Need Help ASAP!!
Answer:
the ring of fire was when the plate boundarys collided. this caused the oceanic plates to rise above the water. the convection and current cause the subduction zone to make a volcano and magma.
Explanation:
The ring of fire was caused by the collision of the plate boundaries. As a result, the oceanic plates moved upward, until they were above the water. Both convection and current are responsible for the formation of a volcano and magma in the subduction zone.
What is a volcano?A breach in the crust of a planetary-mass object, such as the Earth, can give rise to the formation of a volcano. This rupture makes it possible for molten lava, volcanic ash, and gases to escape from a magma chamber located under the surface. Volcanoes are most common on Earth at locations where two or more tectonic plates are moving in opposite directions, and the majority of volcanoes are found deep within the ocean.
Volcanic rock and ash make farmers' crops grow better. The volcano attracts tourists, boosting the local economy. Locals get free electricity from geothermal energy.

Moho
Liquid Solid
no way to know
O Glutenburg
Answer: Glutenburg
Explanation:
The earth subsurface is composed of distinct layers stacked on top of one another. The Layers are named and usually subjected to high temperature and pressure as the depth increases. The layers distinctly include ; the crust, the mantle and the core. The Glutenburg boundary exists between the mantle and the outer core . Hence, it exists at greater depth, hence higher density than the mohorovicic boundary which separates the mantle and the crust. The moho exists at a depth of about 35 km compared to Glutenburg which occurs at a far greater depth of over 2500km beneath the continental crust.

Studies of fat cells and thyroid cells show that fat cells have fewer mitochondria than thyroid cells. A biologist would most likely infer that fat tissue does not require energy
requires less energy than thyroid tissue
has energy requirements equal to those of thyroid tissue
requires more energy than thyroid tissue
Answer:
requires less energy than thyroid tissue
Explanation:
Thyroid tissue's energy requirement is more than fat tissue. option D is the correct answer.
What is the function of thyroid cells?The thyroid plays an important role in regulating the body's metabolism. The hormones it secretes help govern many functions of the body like how the body produces heat, consumes oxygen, and uses energy.
Virtually every tissue in the body is affected or regulated by thyroid hormone. Think where mitochondria are found in the greatest numbers - they are found (for example) in liver cells, kidney cells, muscle cells, etc. These tissues carry out a lot of work and thus require lots of energy. Fat is a storage product that sits there until required but the thyroid does lots of work involved in metabolism and therefore requires plenty of energy.

water is boiled and steam is produced. this is a physical change because the water particles;
A. have turned into something new
B. are still water particles
C. have reacted with each other
D. have been destroyed
Answer:
B the answer is b
Explanation:
Water is boiled and steam is produced, which is a physical change because the water particles are still water particles, as they are in Option B, because the form is changed rather than the chemical nature.
What is the significance of the physical change?The physical change is significant as it is reversible, and these changes do not involve a chemical reaction, so the original substance can be altered by reversing the process, such as from ice to water. These processes are used in industrial processes to separate, purify, or refine materials; in cooking and food preparation, such as heating, freezing, and mixing, they are used to prepare food and change its texture, taste, appearance, etc.
Hence, water is boiled and steam is produced, which is a physical change because the water particles are still water particles, as they are in Option B, because the form is changed rather than the chemical nature.

A researcher performed an experiment in which he exposed young corn plants to a harmless, radioactive form of carbon dioxide gas containing carbon-14 instead of carbon-12. He then began feeding corn produced by the plants to a small group of goats. After several weeks, the researchers took blood and tissue samples from the goats. He was able to detect increased concentrations of carbon-14 in the goats' lipids, proteins, carbohydrates, and DNA
Answer:
See the answer below
Explanation:
A researcher performed an experiment in which he exposed young corn plants to a harmless, radioactive form of carbon dioxide gas containing carbon-14 instead of carbon-12. he then began feeding corn produced by the plants to a small group of goats. after several weeks, the researcher took blood and tissue samples from the goats. he was able to detect increased concentrations of carbon-14 in the goats' lipids, proteins, carbohydrates, and dna. which statement best explains the researcher's findings?
a. uptake of radioactive carbon dioxide gas caused carbon atoms to be found in places they wouldn't normally be found.
b. carbon atoms found in the sugar molecules of the corn were used by the goats' bodies to form other large molecules.
c. like the corn plants, the goats experienced prolonged exposure to carbon dioxide gas containing carbon-14.
d. eating corn containing radioactive carbon-14 caused many of the goats' other carbon atoms to become radioactive.
The correct answer here would be that the carbon atoms found in the sugar molecules of the corn were used by the goats' bodies to form other large molecules.
This is usually what happens when organisms feed on nutrient-containing substances. The nutrients are extracted during digestion and are utilized in the anabolic processing of important biomolecules in the body of the organism.
Carbon is an important element in all biomolecules of life such as lipids, proteins, nucleic acids, etc. and as such, the carbon present in the corn consumed by the goats must have been used to form some of these molecules in the bodies of the goats.
The correct option is b.
