Answer:

Genus and species.

Explanation:

The system of the biological classification is important to classify the organisms into different group. Linnaeus is known as the father of biological classification.

The naming of the species that comprises two levels are known as known as biological nomenclature. The first name of the organism represents the genus and the second name represent the species to which the organisms belong.

Thus, the answer is option (3).

Twin and adoption studies shed light on the relative influence of genetics and environment by examining the similarities between identical twins raised apart and between adopted children and their biological or adoptive families.

Twin studies are a cornerstone of quantitative genetics, which analyze degrees of similarity between individuals to infer the respective roles of genetic and environmental factors. Identical twins separated at birth and raised in different environments present a unique opportunity to isolate the effects of their genetic makeup from environmental influences, since they share identical genes but not the same environment.

An adoption study further aids in understanding nature vs. nurture, where researchers look for similarities between adopted children and their biological versus adoptive parents. A closer resemblance to biological parents suggests genetic influences, while greater similarity to adoptive parents indicates environmental effects.

Beyond twins and adopted individuals, family studies, including extended family, siblings, and half-siblings, expand our knowledge of genetic and environmental contributions to traits and behavior.

Final answer:

Primitive traits are typical of broader clades as they are inherited from a distant ancestor and are shared among a large group of organisms, whereas derived traits are characteristic of smaller clades and indicate more recent evolutionary changes.

Explanation:

Primitive traits, also known as plesiomorphic traits, are typical of broader clades because these traits were present in distant ancestors. These traits persist over large groups of organisms that descend from a common ancestor. For instance, all mammals possess body hair because they share a common ancestor that exhibited this feature, making it a primitive trait within the clade of mammals. In contrast, derived traits, or apomorphic traits, are indicative of smaller clades as they represent changes that occurred after the clade diverged from other lineages. For example, the trait of walking on two legs is considered a derived trait in humans as it developed after our lineage split from other primates.

It is important to recognize that the classification of a trait as primitive or derived is relative and can vary depending on the taxa being compared. Additionally, when a lineage splits into two, it is common for one to retain more of the ancestral traits, while the other develops more derived traits. Understanding these traits helps us reconstruct evolutionary relationships and determine how closely related different species are within the clades they belong to.

The upper layer of desert soil is rich in minerals because there is little leaching. The correct option is B.

Leaching is a mass transfer process that occurs when a substance is extracted from a solid material that has come into contact with a liquid.

The normal mechanism by which water-soluble compounds from soil or waste are washed out is leaching.

In geology, leaching is the loss of soluble substances and colloids from the top layer of soil due to percolating precipitation. Materials that are lost are carried downward and typically redeposited in a lower layer.

As a result of this transport, the top layer is porous and open, and the bottom layer is dense and compact.

Because there is little leaching, the upper layer of desert soil is rich in minerals.

Thus, the correct option is B.

Answer:

study island

Explanation:

A chromosome unfolding enhances transportation by making DNA segments accessible for transcription. Hence, the correct option is option 1.

When a chromosome unfolds itself, the process enhances transportation by allowing specific segments of DNA to become accessible for transcription. The nucleosomes, which are complex structures of DNA and protein, can slide down the DNA to open up chromosomal regions. This opening of the chromatin structure is vital for the transcriptional machinery, such as RNA polymerase, to initiate the transcription of DNA into RNA. Hence, accessibility is significantly increased as the unfolded DNA provides an opportunity for transcription factors and RNA polymerase to bind to the exposed DNA sequences and carry out the transcription process.

Accessible, transcriptionally active regions of DNA are known as euchromatin, while DNA packaged so that it is inaccessible to regulatory protein binding is known as heterochromatin. Essentially, chromatin dynamics—such as the opening and closing of nucleosomes—allow DNA to be transcribed, move histones to open or close a chromosomal region, and are temporary changes that contribute to gene regulation.

Gene expression allows one cell such as brain cell to take a different shape and function compared to the other cell such as arm cell.

Gene expression is the process which involves the transfer of information from a gene that is used in the synthesis of a functional gene product enables the production of end products, such as protein or non-coding RNA, which ultimately affect the phenotype of an individual, as the final effect.

Gene expression depends upon several factors such as, genetic makeup, exposure to harmful substances, environmental influences, and age of the organism, all can affect gene expressivity and hence the phenotype of the organism.

In gene expression, genes which are inactive are silent or unavailable for the protein development in cells. Because of this reason, the cells which carry the same instructions becomes a brain cell and another a skin cell.

Final answer:

Diatoms play a crucial role in aquatic ecosystems by contributing significantly to global oxygen and carbon production, trapping carbon dioxide at the sea floor, and having economic interactions with humans through the use of diatomaceous earth in various industrial applications. They also influence aquatic biodiversity through their competitive interactions with other phytoplankton.

Explanation:

Diatoms are significantly important to ecosystems beyond being a source of food due to their roles in global ecology, economic interactions with humans, and their competition with other phytoplankton. Despite their minuscule size, diatoms are responsible for over 40% of the ocean's production of oxygen and reduced carbon, playing a crucial part in essential biogeochemical cycles including those for oxygen, carbon, and silica. Their unique silicon-based cell walls, requiring considerably less energy to construct than carbohydrate-based walls, give them competitive advantages in aquatic environments. Furthermore, diatoms contribute to the carbon cycle by sinking to the sea floor when they die in large numbers, trapping carbon dioxide that they had consumed during photosynthesis and thus reducing the amount returned to the atmosphere. Besides their ecological importance, diatoms have various economic interactions with humans. Their cell walls, preserved as diatomaceous earth, have numerous industrial applications such as in filters, abrasives, and even in toothpaste. Lastly, diatoms can outcompete other algae for resources in aquatic environments, especially in conditions where silicon is abundant, thereby influencing the biodiversity and stability of aquatic ecosystems.

The correct answer will be option-D.

Explanation:

Fungi forms symbiotic or mutual relationship with higher plants known as mycorrhizae.

These mycorrhizae could be present on the tree parts like stem which form the ectomycorrhizae and some live inside the plant parts like in the roots and known as endo-mycorrhizae.

The fungi provide useful nutrient like they absorb phosphorus from the soil and provide it to the plants and in return plant give shelter to these fungi.

Answer:

the answer is b. scarcity of drinking water

Explanation:

In the period when the lush ancient forests exited on Earth, the ones that provided the material for the formation of the coal that we use nowadays, Australia did not provide the right conditions for the existence of these forests.

The problem was that Australia was located very close to the South Pole in that period. Because of its location, Australia was colder and drier than most of the landmass on the Earth. By having less precipitation, and colder climate, Australia was not suitable for the tropical rainforests of that period, thus it did not had the material from which the coal formed latter on in the geological time scale.

Answer:

Explanation: Cellular respiration is a multi-step process that cells use to convert biochemical energy from nutrients into adenosine triphosphate (ATP), and release waste products. It involves three main stages

Glycolysis: Glucose → 2 Pyruvate + 2 ATP + 2 NADH

Citric Acid Cycle: 2 Pyruvate → 2 Acetyl-CoA → 4 CO2 + 6 NADH + 2 FADH2 + 2 ATP

Oxidative Phosphorylation: NADH + FADH2 → ETC → Proton Gradient → ATP Synthase → ATP (approximately 34 ATP)

Overall, cellular respiration produces up to 38 ATP molecules from one molecule of glucose (2 from glycolysis, 2 from the Krebs cycle, and about 34 from oxidative phosphorylation), although the actual yield can be slightly lower due to varying efficiencies and conditions within the cell
