Answer: 5 would have brown hair.

Explanation:

In the cross between two heterozygous black guinea pigs, out of 20 offspring, we can expect approximately 15 to have black hair and approximately 5 to have brown hair, following Mendelian genetics principles.

In genetics, a dominant allele masks the effect of the recessive allele making it less likely to appear in the offspring. In the cross of two heterozygous black guinea pigs, the four possible combinations of their alleles are BB, Bb, bB, and bb. The first three combinations will produce black offspring, while bb will give a brown guinea pig. This results in a 3:1 ratio, hence in the case of 20 offspring, about 15 would be expected to have black hair while 5 would have brown hair.

Hello There!

The "Lungs" are pairs of organs within the rib cage.

In the "Lungs" the mucus traps dust and pollen

Answer:

The correct answer will be option-It traps particles such as dust and pollen.

Explanation:

The mucus produced in the lungs is also known as the airway surface liquid or ASL and the mucus formed inside the lungs is known as phlegm. The mucus is composed of the water, ions and the macro-molecules which can trap and has anti-protease and anti-microbial activity.

This mucus forms a thin layer of the fluid in the luminal surface of the airway to which protects the lungs from the foreign particles and chemicals which can enter.

Thus, option-It traps particles such as dust and pollen is the correct answer.

Protein (a macromolecule) is formed from a polypeptide sequence translated via RNA .

During translation, a cell “reads” the information in a messenger RNA (mRNA) and uses it to build a protein.

In the process of transcription, a segment of DNA, more specifically an amino acid sequence, is copied (or transcribed) into RNA.

High heat capacity of water results from its high boiling point. Thus, option D is correct.

Water has a few significant actual properties. Albeit these properties are recognizable as a result of the inescapability of water, a large portion of the actual properties of water are very abnormal.

Given the low molar mass of its constituent atoms, water has bizarrely huge upsides of thickness, surface strain, intensity of vaporization, and entropy of vaporization, which can all be attributed to the broad hydrogen holding connections present in fluid water.

B) Bacteria can be treated with antibiotics, viruses cannot.

Antibiotics have no target when dealing with viruses. Antibiotics work on bacteria because it targets the growth machinery in bacteria. Viruses are found inside a human cell and reproduce by inserting their DNA into a human cell. There are antivirals and vaccines out there for viruses. Our body’s immune system fights against viruses with antibodies!

Answer:

That is correct on USATestPrep

Explanation:

Bacteria can be treated with antibiotics, viruses cannot.

Antibiotics won't treat viral infections because they can't kill viruses. Viruses are not living and depend on a host cell to provide the machinery for reproduction.

So the 1st description is interspecific competition

2nd one is intraspecific competition

3rd one is interference

4th one is exploitation

Competition can be primarily categorized into perfect and monopolistic types with both showing demand elasticity in the long-run. Perfect competition has a perfectly elastic demand curve, while monopolistic competition has a demand curve that is not perfectly elastic, allowing some leeway in pricing.

Types of Market Competition

Competition in economic markets can be categorized into different types which have distinct characteristics. The main types are perfect competition and monopolistic competition. In both cases, in the long-run, consumers are sensitive to price changes, which signifies demand elasticity. However, they differ in how firms face the price-demand relationship. Perfectly competitive markets feature perfectly elastic demand curves, meaning any price increase could eliminate demand for a product. Conversely, monopolistic competition presents a not perfectly elastic demand curve; firms have some market power to raise prices without losing all customers.

Key Comparisons and Concepts

Perfect competition serves as a theoretical benchmark to evaluate other market structures, which include monopolistic, oligopoly, and monopoly competetion. The amount of competition in a market impacts prices, as well as the demand and supply of goods and services. Moreover, exploring the evolutionary effects of intraspecific (within a species) and interspecific (between different species) competition can provide insights into how competition influences performance and survival strategies in biological ecosystems.

B) particulate matter!

Sunny~ ☺

Particulate matter is not involved in the chemical reaction, which produces smog.  

• The air pollution, which diminishes visibility is smog.  

• The majority of the smog that one sees today is the photochemical smog.  

• It is generated when sunlight reacts with atleast one volatile compound and nitrogen oxides in the atmosphere.  

• The nitrogen oxides come from coal power plants, factory emissions, and car exhaust.  

• The volatile compounds are discharged from paints, gasoline, and many cleaning solvents. When sunlight react with these chemicals, they produce ground level ozone or smog and airborne particles.  

• The mixture of solid particles and liquid droplets found in the air is known as the particulate matter.  

• The particulate matter has no role in the production of smog.

Answer:

the plant will die

Explanation:

If a plant disease destroys all of a plant's chloroplasts, then it would be detrimental for the plant and for all of the animal kingdom, as animals depend on the plant for food and for oxygen.

Plants are the producers of the ecosystem that produces oxygen for itself and for all the animals, along with glucose. The chloroplast is the plant organelle that has thylakoids and stroma; in the thylakoids, water hydrolysis takes place and ATP is released, and in the stroma, carbon dioxide is fixed to form glucose. If these do not occur, the plant will be unable to produce all of them. Without the chloroplast and without food, they will perish.

Hence If a plant disease destroys all of a plant's chloroplasts, then it would be detrimental for the plant and for all of the animal kingdom, as animals depend on the plant for food and for oxygen.

Multicellular plant-like protists include seaweed and kelp, which perform photosynthesis like plants but do not have true stems, roots, or leaves. Kelp can grow exceptionally large and forms underwater forests, serving an essential role in marine ecosystems.

Among the plant-like protists, the ones that are multicellular include seaweed and kelp. These organisms are akin to plants in that they also contain chlorophyll and perform photosynthesis to create their own food. However, they differ from plants as they do not have true stems, roots, or leaves and lack cellular specialization or differentiation into tissues.

Examples of multicellular, plant-like protists are seaweed, kelp, and other forms of green, red, and brown algae. Kelp is particularly noteworthy because it can grow over 100 meters long and forms vast underwater 'forests.' Although most protists are microscopic and unicellular, these multicellular protists display the enormous diversity in size and form that exists within the protist kingdom.
