Answer:

the answer is primary succession! why?

Explanation:

well it means, when new life begins in an area with no existing community or soil. That should help you guys!

Primary succession is most likely to occur after a lava flow has destroyed all life in a natural community. The correct option is B.

When a new piece of land is produced or is first exposed, primary succession occurs.

This may occur, for instance, when lava solidifies and forms new rocks or when a glacier recedes and reveals bare rocks. In the initial succession, organisms have to start over.

In primary succession, living organisms first occupy newly exposed or newly created rock.

In secondary succession, a previously inhabited area is disrupted, then recolonized as a result of the disturbance.

The likelihood of primary succession is highest when a lava flow has wiped out all life in a natural community.

Thus, the correct option is B.

The omnivorous flock will eat the most as it eats both insects and seeds. With the removal of fruit it will not be affected much.

The herbivorous flock will eat the least as it has the option to eat seeds only after the removal of fruit.

Explanation:

Let us take the example of Finches. Finches have many different species with different variations adaptable to conditions favorable as per availability of the type of food.

Lets say -

Species X and Y is provided with insects, seeds and fruit.

Species X - Omnivorous

Species Y - Herbivorous

The species X will be able to eat the most as it is an Omnivore.

The omnivorous flock will eat the most as it eats both insects and seeds. With the removal of fruit it will not be affected much.

Species Y will be able to eat the least as it is an herbivore.

The herbivorous flock will eat the least as it has the option to eat seeds only after the removal of fruit.

Omnivore birds can eat both vegetarian ad non-vegetarian. Flock A will be able to eat the most.

The highest grade metamorphic rocks will be formed at high temperatures and high pressures.

Explanation:

Metamorphic rocks can be described as the type of rocks which are formed by a change in the form of the existing rocks. In other words, metamorphosis of igneous, sedimentary or existing metamorphic rocks leads to the production of metamorphic rocks. High temperature and pressure are required by the rocks to change its form and develop into metamorphic rocks. Temperatures usually more than 320 degree Celsius are required for high-grade metamorphism.

Answer:2.)One start codon and one stop codon are used for its synthesis.

3.)The piece of genetic code used for its production contains 11 codons.

Explanation: A codon is a nucleotide sequence on the mRNA that is made up of three nucleotides molecules. A codon is a nucleotide sequence that codes for a specific amino acid. Every amino acid is coded for by at least one codon. Some amino acids are coded for by more than one codon.

During protein synthesis, every protein is synthesized using one start codon and one stop codon. A start codon signals the beginning of translation while the stop codon signals the end of translation. The start codon codes for methionine while the stop codon codes for no amino acid. Therefore, a protein whose genetic sequence has 11 codons is synthesized using a piece of genetic code containing 11 codons.

The true statements are that [Option 2] one start codon, and one stop codon are used for its synthesis, and the genetic code contains 11 codons.

All cells require energy to power their life processes. Therefore all cells must carry some form of cellular respiration that is designed to provide energy for these processes. Usually, some form of nutrient for the cell, like glucose, is broken down, and the energy in the binds used to power the cell’s activities.

10.

ATPs are the energy currency of cells. Energy is stored in its phosphate bonds. When a cell requires energy, ATPs molecules are broken down to ADP + Pi and the energy in the broken bond is used to power the activity.  The more energy is required the more ATPs are broken down. Some of this energy, however, is lost as heat energy since the process of transformation of energy is inherently inefficient.

11.

When the plant is exposed to sunlight, the light stage of photosynthesis is very active. This phase involves the use of sunlight energy to split water molecules so as to harness the high energy electrons that emanate from this process called photolysis. The energy of the electrons is harnessed to make ATPs by photophosphorylation. Oxygen is usually evolved as a byproduct. Therefore the high activity of the light stage means more oxygen is evolved.

The alleles for short will be tt and for tall TT

Explanation:

The recessive alleles are written in small alphabets in Mendelian genetics so the alleles for short is tt.

They must be homozygous to express the phenotypic trait of short height in progeny.

tt = short

suppose if a homozygous tall and homozygous short is crossed

all the progeny will be heterozygous tall. Tt 4:0 ( no short progeny)

Suppose Tt is crossed with Tt

If heterozygous tall are crossed then genotype ratio will be

Tt:TT:tt

Water falls from a reservoir through a channel to a turbine. The water turns the turbines, which allows the generator to make electricity

Explanation:

Hydroelectric power is generated from free falling water through a river channel.

The flow of water at a high speed creates water current and the kinetic energy of the water movement spins turbine attached with a generator. This produces a rotating energy which spins the generator and the coil inside.

The magnetic spinning of coiled wire inside the generator produces electric current which is then stored and transmitted through electric power grid lines to supply electric current.

Hydroelectric power is generated by utilizing the potential energy of water stored in a reservoir behind a dam. The water is released to flow through turbines, which spin and drive a generator to produce electricity, subsequently transmitted through power lines.

The process of creating hydroelectric power involves several critical steps. First, a dam is constructed across a river to form a reservoir, trapping the water and creating stored potential energy due to the water's elevated position. When the need for electricity arises, water is released from the reservoir and flows through a penstock, a narrow channel leading to the turbines. As water flows with kinetic energy through the turbines, it causes the turbines to rotate.

These turbines are connected to a generator. The rotational motion of the turbines is converted into electrical energy by the generator, which operates on the principle of electromagnetic induction. Once the electricity is generated, it is transmitted via power lines to be distributed for use. The water that passes through the turbines continues its flow downriver.

Hydropower is a form of renewable energy, and the efficiency of this process can be quite high, sometimes approaching 90% in terms of energy conversion. While the most common form of hydroelectric power comes from dams and reservoirs, other methods include run-of-the-river systems and less frequently, tidal and wave energy, which also harness the power of moving water but through different mechanisms.

Answer:

The two teams pull with equal force as long as they're pulling?

Explanation:

Don't @ me lol

Final answer:

In tug of war, movement toward one team indicates unbalanced forces, where the stronger team exerts a larger force causing movement. If the rope snaps, the tension is released, and teams accelerate in the direction they were pulling.

Explanation:

In a game of tug of war, when one team is moving toward the other, this indicates that there are unbalanced forces at play. Initially, if both teams exert equal forces, the situation is in equilibrium, and the rope does not move. However, when one team starts to overpower the other, there is a resultant force in the direction of the stronger team causing the movement. If the rope suddenly snaps, the forces exerted by the players are no longer balanced, and the force of tension in the rope that was opposing each team's pull is released. The result is that the teams will momentarily accelerate in the direction they were pulling due to inertia.

Number two is the only statement that doesnt mention gene variations.

An asexually reproducing single-celled organism produces 10 offspring in its lifetime showing no genetic variability because they are identical to their parents, hence option 2 is correct.

Offspring are physically and genetically similar to their parents. They are a clone or exact replicas of the parent. Asexual reproduction doesn't involve any genetic material being recombined.

The populations of organisms that reproduce asexually increase and spread out more quickly than those that reproduce sexually because they need fewer resources for the same amount of reproduction.

Therefore, asexual populations, on the other hand, have less genetic variation and, as a result, are less able to adapt to shifting surroundings.

Explanation:

If female cardinals change their mate selection criteria away from red feather coloration, the vibrancy of male cardinal feathers could decrease over time due to the reduction in selection pressure for that trait, exemplifying directional selection.

If female cardinals start choosing mates based on criteria other than the male cardinals' red feather color, over time, the selection pressure for vibrant red feathers may decrease. This could lead to a change in the cardinal population where the color of the male cardinals becomes less vibrant or more variable, as the trait would no longer confer a significant advantage in reproductive success. This is an example of directional selection, where the environment, including mate preferences, drive changes in traits over generations.

Answer:

The Industrial Revolution began in Europe in around 1750 CE (AD). Prior to the Industrial Revolution, motors, machines, and production lines didn't exist. A great many people needed to develop and chase their own nourishment, make all that they possessed (like their homes, garments, and devices), and travel by foot (or a pony or carriage in the event that they were affluent). Power and indoor pipes were obscure in Europe. There were no such things as trains, phones, or cameras.

The Industrial Revolution lead to government since it gave the motive and the ability to imperialize Asia and Africa.

The primary significant innovations that started the Industrial Revolution were the steam motor and turning jenny. The steam motor was made in the mid 1700s, and culminated in the late 1700s. Utilizing a coal or wood fire to bubble water, the motor worked by driving the high-forced steam to turn gears. This motor turned into the reason for train motors and machines in industrial facilities,both imperative to colonialism.

Industrialization drove to imperialism for a few reasons. ... Industrialized nations discovered they had the option to acquire less expensive assets from their settlements than from different nations. In this manner, nations needed to pick up colonies so they could acquire the assets required in theirindustries.

The Industrial Revolution's demand for raw materials and new markets led to increased European imperialism, as nations sought to expand their global influence and economic power.

Technological advancements in transportation and communication further facilitated this imperial expansion.

These technological innovations made it easier for European countries to establish and maintain their overseas empires, thus directly linking industrial progress with imperial expansion.

Correct question is: How was the Industrial Revolution linked to imperialism?
