Explanation:

The water cycle disruptions have most affected wading birds by:The release of water dilutes food sources for their young.This is because wading birds depend on the natural flow of water to bring in fish and other small aquatic organisms which are a vital part of their diet. When the water cycle is disrupted by the canals and levees, the water flow changes, and the amount and timing of these organisms can be impacted, making it harder for wading birds to find food for their young. Therefore, option (a) is the correct answer.Option (b) is incorrect because longer-legged birds are not necessarily more adapted to survive in higher water levels.Option (c) is incorrect because water quality may not necessarily improve due to runoff.Option (d) is incorrect because reduced salinity may not be a direct cause of increased egg-laying.

D: 4.6 x \(10^{9}\)

Explanation:

4.6 x 10^{9} = 4,600,000,000

Earth is approximately, 4.6 billion = 4,600,000,000 = 4.6 x 10^{9}

The estimated age of Earth is 4.6x10⁹ years (D).

Scientists estimate the age of Earth through various methods, including radiometric dating of rocks and minerals. By analyzing the isotopes present in rocks and minerals, scientists can determine the decay rates of radioactive isotopes and calculate the time since the formation of those rocks.

Based on extensive studies and evidence, the current estimated age of Earth is approximately 4.6 billion years (4.6x10^9 years). This estimation is supported by multiple lines of evidence, including radiometric dating of rocks from different geological formations, lunar samples brought back from the Moon, and meteorites.

The age of 4.6 billion years is consistent with the age of the oldest rocks found on Earth's surface and the ages of the Moon and meteorites, which are believed to have formed around the same time as Earth. These dating methods provide a reliable framework for understanding Earth's geological history and the processes that have shaped our planet over billions of years.

It's important to note that scientific estimates and understanding of Earth's age continue to evolve as new evidence and research emerge. However, the current consensus among scientists is that the age of Earth is approximately 4.6 billion years, as indicated by extensive geological and radiometric dating studies.

From the analysis of the 2 equations: X = 3/4 and Y = 5/4

The equations can be solved using subtracting one of the two equations from the other.

Let's label the two equations:

Y=3x-1 .................... equation 1

Y=2-X..................... equation 2

Equation 2 can be rearranged such that:

Y = -X+2

Subtracting equation 2 from 1:

Y=3x-1

Y = -X+2

0 = 4X -3

4X = 3

  X = 3/4

Substitute X = 3/4 into any of equations 1 or 2 to determine Y.

Y = 3(3/4) - 1

Answer:

I would argue that animal pollination of blooming plants is the most successful form of sexual reproduction for generating genetic variation.

According to science, animal pollination enables the transport of pollen from one flower to another, increasing the genetic variety of the population. This is so that there is a greater potential of genetic mixing because different animals may visit various blooms, dispersing pollen from various plants.

Another justification is that, in contrast to wind pollination, animal pollination frequently entails actively moving pollen from one flower to another, which may result in higher genetic variety. While wind-borne pollen frequently travels enormous distances, it also tends to be dispersed by plants that are close relatives. Animals who visit flowers and spread pollen, on the other hand, are more likely to visit a variety of plants, encouraging greater genetic mixing.

Animal pollination also transfers genetic material from one plant to another, rather than only within a single plant or a group of closely related plants, making it more effective in promoting genetic variety than both animal internal fertilisation and external fertilisation.

Correct alternative: a) The yellow color is dominant and the green color is recessive.

As observed in his experiment, Mendel identified that two factors determine the color of peas: a dominant for the yellow color and a recessive that expressed the green.

The dominant gene is the one that determines a characteristic, even when in simple doses in the genotypes. The recessive gene is only expressed when in double dose, because in the presence of a dominant, it becomes inactive.

The relationship between barnacles and whales is considered commensalism, which is a type of symbiotic relationship in which one organism benefits without harming or benefiting the other organism.

Barnacles are a type of sessile organism, which means they are unable to move freely from one location to another. In order to survive, they need to attach themselves to a solid surface, such as a rock or the skin of a whale. When barnacles attach themselves to the skin of a whale, they create a home site where they can filter-feed and reproduce.

While the barnacles benefit from this relationship by gaining a home site, there is no evidence to suggest that the whales benefit or are harmed by having barnacles attached to their skin. Barnacles do not consume or harm the whale's skin or tissues, and there is no evidence to suggest that the presence of barnacles has any impact on the whale's health or behavior.

Therefore, the relationship between barnacles and whales is considered commensalism, which is a type of symbiotic relationship in which one organism benefits without harming or benefiting the other organism.

Answer:

- Binomial nomenclature is a widely accepted naming system, which is used in the naming of living things. Multiple native names make it extraordinarily tough to establish an organism globally and maintain an observation of the variety of species. Thus, it creates quite a lot of confusion. To eliminate this confusion, a normal protocol came up. According to it, every organism would have one scientific title which might be utilized by everybody to establish an organism.

What is binomial nomenclature?

Binomial Nomenclature follows a universally accepted naming system, which is used to provide a scientific name to a known organism.

Binomial Nomenclature also known as the binary nomenclature.

It uses two-terms during the nomenclature of a specie (plants, animals, and living organisms) that is why it called two-term naming system.

The scientific name of an organism or binomial nomenclature consists of two words, such as the generic epithet and describes the genus and the specific epithet and refers to the species of the organism.

Both of this term is written in italic and the genus name is capitalized.

Binomial nomenclature was given by Swedish botanist and physician Carl Linnaeus. He also called the founder of modern taxonomy.

Carl Linnaeus described and classified thousands of species of plants and animals in his book Systema Naturae.In this technique, there are particular guidelines that are followed while naming organisms. This normal algorithm is relevant to plants and animals whereas giving them distinctive names inside a given system.There are two worldwide codes such as the International Code of Botanical Nomenclature (ICBN) deal with the biological nomenclature for plants and the International Code of Zoological Nomenclature (ICZN) deal with the biological nomenclature of animals.

These two codes agreed upon by all of the biologists over the world for the naming protocol. These codes ensure that every organism will get a selected identity and that identity is globally recognized.

Summary of the limitation binomial nominclature:

- Some of the main drawbacks of binomial nomenclature are: If two or more names are actually in use in compliance with the priority rule, the appropriate name will be used first and the other names will end up being synonyms because authenticity is synonymous with the senior.
