Pioneer species are the first plants and animals to colonize an area that has been disturbed or newly formed, and these species are adapted to harsh environmental conditions such as high winds, harsh temperatures, a lack of nutrients, etc.

The important role of pioneer species in succession is that they prepare the way for other species to establish themselves in the ecosystem and help to break down rocks and other materials, making the soil more fertile and hospitable for other plants to grow. They also help to trap sediment and organic matter, creating a layer of soil that can support other types of vegetation.

Hence, pioneer species are the first plants and animals to colonize an area and are adapted to harsh environmental conditions such as high winds, harsh temperatures, a lack of nutrients, etc.

D) Cities can be built in uninhabitable places

Methods for Transportation of water can be:

Aqueducts, which include pipelines, canals, tunnels and bridges.

Water transportation impacts every state, even those that do not border a navigable river or coast due to  the volume of cargo that comes in and out of our country via water. An astonishing two billion tons of domestic and international cargo travels through ports and on waterways.

Thus, the benefit out of the following options for using technology to transport water is that cities can be built in uninhabitable places, i.e. option D.

Coral bleaching can be defined as a condition in which occurs in the corals during the stress conditions.

Due to increase in the temperature of the surrounding water corals generally expel the algae that was living in the coral and due to this the corals appear white.  

This is caused in the shallow parts because they are more susceptible to temperature change.

Hence, the correct answer is option B

A natural or artificial body that revolves around a celestial body of greater mass is called a satellite.

A satellite or artificial satellite is an object intentionally placed into orbit in outer space. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators.

Moreover, there are hundreds of satellites in operation. They are used for diverse purposes such as weather forecasting, television signal, amateur radio and internet communications and the Global Positioning System.

Therefore, they are also used to look outward at the solar system for research and data gathering purposes.

Answer:

 Eyes, Tongue, and Nose. Explanation:

DNA replication is vital before mitosis to ensure that each resulting daughter cell gets an identical copy of the DNA. Cell cycle checkpoints ensure that DNA duplication occurs without errors or mutations. This is especially important in sexual reproduction and during meiosis.

DNA duplication, or DNA replication, is crucial before mitosis, which is a type of cell division. This process ensures that each resulting daughter cell receives an identical copy of the DNA so they can function correctly. The DNA replication happens during the synthesis phase or S phase of the cell cycle, prior to mitosis or meiosis.

To ensure that the DNA duplication happens without any errors leading to mutations, the cell has internal control mechanisms called checkpoints. These checkpoints confirm that conditions are favorable for progression to the next stage in the cell cycle and prevent compromised cells from further divisions.

The goal is to produce daughter cells that are exact duplicates of the parent cell. Hence, the DNA replication plays a critical part in sexual reproduction by providing every new cell a correct copy of DNA during cell division. This importance is highlighted during meiosis, where DNA replication precedes the two rounds of nuclear division, resulting in four daughter cells, each with half the number of chromosomes as the parent cell.

A Punnett square is a diagrammatic tool that is used to predict the percentage of offspring that will have a specific trait during a cross between two parents.

A Punnett square is a very useful tool in the study of genetics which is used to predict the offspring that a cross between two parents will produce.

The Punnett square provides information about the genotype as well as the phenotype of the offspring.

It also provides information about the ratio in which the genotype and phenotype of the offspring occur.

Therefore, a Punnett square is used to predict the percentage of offspring that will have a specific trait during a cross between two parents.

When both parents are heterozygous for a trait, the offspring have an equal chance of inheriting the four possible genotype combinations 'AA', 'Aa', 'aA', or 'aa'. Phenotypically, this equates to a 3:1 ratio of dominant to recessive traits. The probability of an offspring exhibiting the dominant phenotype is 3/4, and for the recessive phenotype, it's 1/4.

If both the mother and the father are heterozygous for a trait, we can use the product and sum rules to calculate the genotype probabilities. In this scenario, we can adopt a method known as a Punnett Square to visualize the possible outcomes. Consider each parent can donate one of two different alleles. Let's denote these alleles as 'A' and 'a'.

Because each parent is heterozygous ('Aa'), the possible allele combinations for the offspring are: 'AA', 'Aa', 'aA', or 'aa'. Each of these combinations, representing the different genotypes, have equal likelihood of occurring. Therefore, the offspring show a genotypic ratio of 1 AA: 2 Aa :1 aa.

Now considering phenotype, the 'AA' and 'Aa' combinations would exhibit the dominant phenotype, and 'aa' would exhibit the recessive phenotype. Hence, if we apply the sum rule of probability, we expect the offspring to show a phenotypic ratio of 3 (dominant):1 (recessive). This means, the probability of an offspring exhibiting the dominant phenotype is 3/4 and the recessive phenotype is 1/4.

Explanation:

Examples of evolution include the variation in the peppered moth's color, the similar winter adaptations of the unrelated arctic fox and ptarmigan, and changes in the beak shapes of Galápagos finches due to natural selection.

Examples of evolution can be seen in various forms. One of the classic examples often used in biology textbooks is the peppered moth. Changes in the population's allele frequencies in light and dark forms, which represents small-scale evolution, could be traced back to this species.

Another example of evolution is the evolutionary convergence observed in unrelated species sharing the same environments. The arctic fox and ptarmigan, though not related, adapt to white phenotypes during winter to blend with the snow and ice, a testament to similar selection pressures.

Additionally, the Galápagos finches offer an illustration of evolution through natural selection. Shifts in the distribution of beak shapes from one generation to the next, caused by variations in environmental conditions, show how traits passed on can influence survival and reproduction.
