Answer: Diffusion occurs due to the random movement of particles. It usually happens due to a concentration gradient, meaning that molecules move from an area of high concentration to an area of lower concentration.

Explanation:

Answer:

first option

Answer:

Yes

Explanation:

Speed is a scalar quantity (only has a magnitude). It signifies the rate of change of an object's movement.

Velocity is a vector quantity that signifies the rate of change of movement but also the direction of an object's movement.

Since the car turns, its direction changes, so the velocity changes.

Explanation:

The structure of DNA can be compared to a ladder. It has an alternating chemical phosphate and sugar backbone, making the 'sides' of the ladder. ... These bases make up the 'rungs' of the ladder, and are attached to the backbone where the deoxyribose (sugar) molecules are located.

Answer: B. Males of different, closely related species of fireflies signal for mates by flashing different light sequences.

Reproductive isolation refers to the inability of the members of a species to breed with members of other species. Behavioral isolation is a type of reproductive isolation, in which mating between the members of the species is facilitated by their behavior. It helps members of the same species to identity their mates. It prevents mating between population of distinct species.

Males of different, closely related species of fireflies signal for mates by flashing different light sequences is an example of behavioral isolation because flashing of light by fireflies is the behavioral characteristic which shows their desire for mating. The mates identify the light signals flashed by their partner belonging to the same species.

Answer:

B. Males of different, closely related species of fireflies signal for mates by flashing different light sequences.

Answer:

1. The Los Angeles flood of 1938 was one of the largest floods in the history of Los Angeles, Orange, and Riverside Counties in southern California.

2. The flood was caused by two Pacific storms that swept across the Los Angeles Basin in February-March 1938 and generated almost one year's worth of precipitation in just a few days.

3. The Los Angeles, San Gabriel, and Santa Ana Rivers burst their banks, inundating much of the coastal plain, the San Fernando and San Gabriel Valleys, and the Inland Empire.

4. Flood control structures spared parts of Los Angeles County from destruction, while Orange and Riverside Counties experienced more damage.

5. It caused $78 million of damage ($1.42 billion in 2019 dollars),[2] making it one of the costliest natural disasters in Los Angeles' history.[3] In response to the floods, the U.S. Army Corps of Engineers and other agencies began to channelize local streams in concrete, and built many new flood control dams and debris basins

Explanation:

If Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.

A recessive genetic disorder, such as cystic fibrosis, and an autosomal dominant disorder, such as Huntington's disease, are examples of genetic disorders caused by a gene that can express itself in either a dominant or recessive manner. For example, the disease is represented by the aa. If the male is heterozygous for diseases such as "Aa," then he will produce 25% "aa" type offspring when he crosses with the heterozygous female. When a man is purebred AA and crosses with a heterozygous female, then no offspring will be genetically infected.

Hence, if Individual 3 has children with a woman who is heterozygous for the genetic disorder, then the chance of producing genetically disordered offspring is 25% if the male is heterozygous and 0% if the male is not.

==============================================================

Explanation:

The United States, the United Kingdom, and France are all countries that have capitalistic economies. This means that (for the most part) private industry and the market determines what products are produced and who gets those products. I said "for the most part" because these countries don't follow a purely capitalistic structure. There are some elements of government regulation to ensure that no breakdowns occur. The regulations are also to ensure some level of fairness as well, in addition to preventing things like fraud.

On the other hand, countries like North Korea are known as command economies because the government determines what products are to be made and they determine who gets the products. This means that they set the prices as well to whatever they feel is correct (even if the market may disagree otherwise). The term "communism" is often strongly connected to the term "command economy".

Answer:

The photosynthesis equation is as follows: 6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy from light produces glucose and oxygen.

Explanation: (credit to Chris Hall in Quora)

On the geological scale, the equation for photosynthesis would be the opposite of combustion/respiration: carbon dioxide and water molecules converted into oxygen and carbohydrate (or hydrocarbon) molecules (one unit of -CH2O- per CO2).

However, such a simplistic formula is extremely misleading, especially when talking about individual plants and algae instead of macro-geo-chemistry. The oxidation of water to oxygen (aka the light reactions) is a separate (but concurrent) process from the reduction of carbon dioxide to carbohydrate or hydrocarbon (aka the dark reactions). See my answer to a similar question here: Chris Hall's answer to Where is the most detailed chemical structure breakdown of all steps of photosynthesis that is reliable?

Some bacteria, algae, and plant cells only perform one half of the typical photosynthetic pathway, either to produce energy without making sugar/hydrocarbon or to assimilate carbon dioxide using stored chemical energy rather than using light directly (similar to chemosynthesis). And some bacteria do photosynthesis without making oxygen at all, using sulfur in the place of oxygen.

In short, photosynthesis should be thought-of as a series of sequential processes and not as a single chemical reaction.

Carbohydrates are the nutrients most frequently used as an energy source (containing 4kcal per gram), as they are fast-acting and turn into energy as soon as they are ingested. This energy powers the brain and body. The energy that powers the brain and body is generated when carbohydrates are broken down.

Answer:

D.  decomposers

Explanation:

primary, secondary consumers and producers all eventually die.  Decomposers break the  dead organisms down to nitrogen, carbon and other basic elements that can then be used as nutrients for the new plants.

Answer: Geysers are water that comes out of the ground spurting into the air, wetlands are self-explanatory, while volcanoes are full of magma, not of acid and limestone.The upper layers of soil above the groundwater contains carbon and limestone. The water being combined with carbon becomes acidic which erodes limestone this results in formation of sinkholes and caves.

C) phenotypic plasticity

Explanation:

Organisms might adjust their morphology and physiology to a better performance in environmental heterogeneity.

Generalists species might present a higher magnitude of phenotypic plasticity than specialist species.

These bacteria are notoriously adaptable and might be found in many different environments (terrestrial and/or aquatics) where there is no oxygen due to aerobic decomposition of the organic matter.  

They can be found in anoxic sulfuric environments. In the soil, in estuaries mud, in freshwater, in sewage systems, salty waters, thermal water, sulfur deposits, in oil and gas wells, and even in animals and insects intestine.
