b Specialized cells work only as a team to perform the functions of the body..
c Specialized cells work independently to perform specific functions and also as a team to perform the functions of the body..
d Specialized cells in the body perform all the functions that are necessary to maintain homeostasis.
Homeostasis refers to the maintenance of constant internal conditions in organisms. The best representation would be option 'd' which says that specialized cells in the body perform all functions necessary to maintain homeostasis, working in a coordinated manner.
The term homeostasis refers to the ability of an organism or environment to maintain a constant internal balance, despite external changes. Among the options, the best descriptor for homeostasis would be Specialized cells in the body perform all the functions that are necessary to maintain homeostasis.' This is because all the specialized cells in an organism work together in a coordinated manner to maintain a stable internal environment. For instance, when the body temperature rises, the sweat glands (specialized cells) are activated to cool the body and bring the temperature back to normal.

plz help. need this answered 4 science.
Answer:
Most ocean pollution begins on land.
Much of this runoff flows to the sea, carrying with it agricultural fertilizers and pesticides. Eighty percent of pollution to the marine environment comes from the land. One of the biggest sources is called nonpoint source pollution, which occurs as a result of runoff.
Answer:
Plastic pollution: The ocean is estimated to contain millions of tons of plastic debris, much of which comes from land-based sources.Chemical pollution: The ocean is also contaminated with a wide range of chemicals, including pesticides, herbicides, and industrial and household chemicals.Nutrient pollution: Excess nutrients, such as nitrogen and phosphorus, can enter the ocean from agricultural and urban runoff and contribute to the growth of harmful algal blooms.Oil pollution: Oil spills and other oil discharges into the water can have a negative effect on the animals and marine ecosystems there.

Answer;
-Independent variable
Explanation;
-An independent variable is defines as the variable that is changed or controlled in a scientific experiment. An independent is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable on the other hand, is the variable being tested and measured in a scientific experiment.
-A change in the independent variable directly causes a change in the dependent variable.The independent and dependent variables may be viewed in terms of cause and effect.
b. glycerol is made of fatty acids.
proteins are made of amino acids.
nucleotides are made of nucleic acids.
The correct statement about macromolecules is 'Proteins are made of amino acids'. It should be noted that in other options, the statements have a part reversed and therefore they are incorrect.
The correct statement about macromolecules is 'Proteins are made of amino acids'. Macromolecules are large, complex molecules that have a high molecular weight. They are mostly built from single subunits, or building blocks, called monomers. In this context, amino acids are the monomers that make up proteins which are a type of macromolecule.
To provide some clarity on the incorrect options: `Simple sugars are not made of polysaccharides` but the other way around. Polysaccharides are complex carbohydrates that are made up of simple sugar monomers. Similarly, `glycerol is not made of fatty acids`, rather, it combines with fatty acids to form lipids. Lastly, `nucleotides are not made of nucleic acids`, but nucleic acids are made of nucleotides. So, it's important to understand the relationships between these biochemistry terms to correctly understand the nature of macromolecules.

Answer:
Commensalism/Predation
Explanation:
Based on the scenarios, the feeding relationship in this case can be viewed from two points;
The feeding relationship in the first scenario can be considered as commensalism. It is a form of nutritional relationship between two organisms in which one of them, the commensal benefits, and the other is unaffected in any way.
The bird, being the commensal in this case benefits from the cow because without the cow disrupting and driving out the insects, there will not be any food for the birds to feed on. On the other hand, the cow neither benefit nor suffer from the actions of the birds.
The feeding relationship between the birds and the insects is predator/prey relationship. In predation, the predator kills and feeds on the prey. The predator is usually bigger in size than the prey. The predator is usually well adapted and equipped to hunt for its preferred prey in the environment.
In this case, birds are bigger than insects and are able to feed on the insects. This means they posses all the necessary features to pick, eat and digest the insects.
Hence, the answer could be commensalism/predation depending on the point of focus.
