A salad including lettuce, tomatoes, and onions would be classified as a _________. A) compound B) element C) mixture D) solution
Answer: C) mixture
Explanation:
A mixture can be define as a combination of two or more substances in which the identity of each substances is retained. In a salad lettuce, tomatoes and onions are separate entities which are combined to form a mixture that is salad.
Answer: Mixture
Explanation:
A salad can be defined as plate full of different kinds of vegetables and fruits which are edible.
The plates contains tomatoes which are different in chemical composition, lettuce which is also different in chemical composition and onions which are all mixed together.
Elements having different chemical composition when combined together is known as a mixture.

What substances must animal cells take in from the environment to maintain homeostasis?
What two recurring events in Earth’s history have an impact on the carbon cycle?
Answer: Earth's orbit and climate change.
Explanation: Earth's orbit and climate change have a great impact on the carbon cycle.
The carbon cycle requires optimum temperature and pressure. This temperature can be controlled by the earth's orbit which leads to change in climate.
The climate changed during the earth's history and led to change in the carbon cycle.
Why does extracted chlorophyll fluoresce under UV light while chlorophyll inside intact chloroplasts does not?
Chlorophyll inside intact chloroplasts does not fluoresce under UV light because it is shielded from direct UV exposure by other cellular components. However, extracted chlorophyll fluoresces under UV light due to the absence of shielding elements.
Explanation:Fluorescence is the emission of light by a substance after it absorbs photons of higher energy. Chlorophyll inside intact chloroplasts does not fluoresce under UV light because it is shielded from direct UV exposure by other cellular components such as thylakoid membranes. However, when chlorophyll is extracted from chloroplasts and exposed to UV light, it fluoresces because there is no longer any shielding element present.

examine the diagram below, explain the path a newly formed polypeptide leaving a ribosome may take as it is modified or packaged before use within the cell or outside the cell: please help me.
After translation of the polypeptide in the ribosome, the polypeptide enters the cisternae of the rough endoplasmic reticulum. Here, the folding of the polypeptide begins with the aid of chaperons proteins. At the end of the RER, vesicles with the completely folded protein bud off and enters the Golgi apparatus where the proteins are transported to its destination.
virus life cycles help please! fill in the blank diagram.
Answer:
The virus life cycle consists of 6 stages:
1. Attachment: The protein on the virus capsid attaches itself to the receptors on the ell surface of the host.
2. Penetration: The viruses capsid goes through a conformational change, fusing the virus to the host's cell surface.
3. Uncoating: The virus nucleic DNA is released when the enzymes of the virus or host degrade the capsid of the virus.
4. Replication: Once released the virus DNA undergoes transcription or translation. The replication will be different due to the type of virus invading the host, example DNA virus, RNA virus or viruses with opposite nucleic acid polarity.
5. Assembly: Maturation process occurs, where by the replicated DNA and the virus protein are packed into virions in order to be released from the host.
6. Virion release: The virions can be released either through lysis or budding.

Compare and contrast inbreeding and hybridization
Final answer:
Inbreeding is the mating of closely related individuals within a population, while hybridization involves mating between different species. Inbreeding can lead to a decrease in fitness and reduced crop yield. Hybrids can be less fit or more fit than the parents, driving divergence or fusion between species.
Explanation:
Inbreeding is the mating of closely related individuals, such as siblings or cousins, within a population. It often leads to a decrease in fitness and can cause inbreeding depression, which is a decline in the overall health and vigor of the population. Inbreeding can be a problem in open breeding systems, like crop species, where it can result in reduced crop yield.
Hybridization, on the other hand, involves mating between individuals of different species to produce hybrid offspring. The fitness of hybrids can vary. In some cases, hybrids are less fit than the parents, and this can drive further divergence between the two species. However, hybrids can also be more fit, which can lead to fusion of the two species back into one.
1. What is mitosis in a living cell?
A. the separation of the genetic material of a cell into two completely identical sets, one for each of the daughter cells created during cell division
B. the creation of two daughter cells with half the number of chromosomes that the parent cell has by the process of cell division
C. the creation of a larger amount of cytoplasmic material that can then be split among the daughter cells of a parent cell
D. the separation of existing genetic material by splitting chromatids at the centromere to create two similar nuclei in another cell
2. What is the best definition of diffusion?
A. Random movement of molecules across a concentration gradient until the difference in concentration between two regions is near zero
B. A process in which molecules move across a semipermeable membrane until the number of molecules of water is nearly equal on both sides
C. Net movement of molecules across a permeable membrane bilayer that requires transport proteins
D. The exchange of solute molecules across a permeable membrane from areas of high concentration to areas of low concentration
3. What characteristic makes osmosis different from diffusion?
A. Osmosis occurs through a semipermeable membrane. Diffusion occurs through a permeable membrane.
B. Net movement in osmosis is from areas of higher concentration to areas of lower concentration. Net movement in diffusion occurs from areas of higher concentration to areas of lower concentration.
C. Osmosis requires facilitation by an energy-carrying molecule, such as ATP. Diffusion requires no additional energy to move molecules across the concentration gradient.
D. Osmosis is used for gases, such as oxygen and carbon dioxide. Diffusion is used for water that contains salt or sugar molecules.

Give TWO advantages that cells gain by storing energy in the form of ATP.
Final answer:
Cells store energy in ATP to safely manage energy without increasing cell temperatures and to provide consistent amounts of energy for cellular processes, ensuring efficient cellular growth and function.
Explanation:
Cells gain two main advantages by storing energy in the form of adenosine triphosphate (ATP). First, ATP allows cells to store energy safely and efficiently, preventing the detrimental increase in temperatures that would occur if energy were stored as free energy. This is crucial because excess heat can denature enzymes and destroy the cell's structural integrity. Second, ATP serves as a uniform energy currency for the cell, releasing consistent amounts of energy upon hydrolysis of its high-energy phosphate bonds. This consistency is vital for the myriad of biochemical processes required for normal cellular growth and function, as it ensures that energy is distributed as needed without destabilizing the cell's environment.

Explanation:
Moles are rodents very similar to mice. They typically live underground, spending most of their lives below the earth's surface. Mice, on the other hand, may dig burrows to nest and sleep in, but they spend much of their time above ground. Their nests can be made of cloth, hair, and hay. Because moles live underground, they have developed differently than mice
Final answer:
Rats belong to the group known as rodents, distinguished by their distinctive pair of continuously growing incisors used for gnawing.
Explanation:
To what group do rats belong? Rats, along with mice, beavers, and squirrels, are part of a group known as rodents. Rodents are characterized by their gnawing behavior, which is facilitated by their unique dental structure. They have a single pair of continuously growing incisors in both the upper and lower jaws that must be kept short through gnawing. This differentiates them from other mammalian groups, such as lagomorphs (including rabbits and hares), carnivores (such as cats, dogs, and bears), and insectivores (such as moles and shrews).
The biological classification of rats is important as it helps in understanding their behavior, evolutionary history, and their role in ecosystems. Additionally, recognizing the differences between various animal groups, such as rodents and insectivores, is essential for scientific studies related to embryology, conservation, and pest control.
