Answer:

The electromagnetic spectrum covers electromagnetic waves with frequencies ranging from below one hertz to above 1025 hertz, corresponding to wavelengths from thousands of kilometers down to a fraction of the size of an atomic nucleus. This frequency range is divided into separate bands, and the electromagnetic waves within each frequency band are called by different names; beginning at the low frequency (long wavelength) end of the spectrum these are: radio waves, microwaves, infrared, visible light, ultraviolet, X-rays, and gamma rays at the high-frequency (short wavelength) end. The electromagnetic waves in each of these bands have different characteristics, such as how they are produced, how they interact with matter, and their practical applications. The limit for long wavelengths is the size of the universe itself, while it is thought that the short wavelength limit is in the vicinity of the Planck length.[4] Gamma rays, X-rays, and high ultraviolet are classified as ionizing radiation as their photons have enough energy to ionize atoms, causing chemical reactions.

Explanation:

Answer:Each color has a different wavelength. Red has the longest wavelength, and violet has the shortest wavelength. When all the waves are seen together, they make white light. White light is actually made of all of the colors of the rainbow because it contains all wavelengths, and it is described as poly chromatic light.

The thoughts, memories, feelings, and desires that we are currently cognizant of are all stored in the conscious mind. This is the area of our brain processing that is open to rational thought and discussion.

This also applies to our memory, which is sometimes not conscious but which can be quickly accessed and made cognizant.

According to the majority view in neuroscience, awareness is an innate quality of the brain and its metabolism. The mind and awareness of the being to which the brain belonged vanish when the brain passes away.

what three animals are closley related to a tiger

Answers

Answer:

The tiger's closest living relatives were previously thought to be the Panthera species lion, leopard, and jaguar.

Explanation:

Results of genetic analysis indicate that about 2.88 million years ago, the tiger and the snow leopard lineages diverged from the other Panthera species, and that both may be more closely related to each other than to the lion, leopard and jaguar. The geographic origin of the Panthera is most likely northern Central Asia or the Holarctic region. The tiger–snow leopard lineage dispersed in Southeast Asia during the Miocene.

Panthera zdanskyi is considered to be a sister taxon of the modern tiger. It lived at the beginning of the Pleistocene about two million years ago, its fossil remains were excavated in Gansu province of northwestern China. It was smaller and more "primitive", but functionally and ecologically similar to the modern tiger. It is disputed as to whether it had the striping pattern. Northwestern China is thought to be the origin of the tiger lineage. Tigers grew in size, possibly in response to adaptive radiations of prey species like deer and bovids, which may have occurred in Southeast Asia during the Early Pleistocene.

O ATP absorbs energy as it is converted into ADP + Pi.
ADP + P; release energy as they are converted into ATP.
O When ATP is converted into ADP + Pi , energy is released and used by the cell.
O When ADP + Pi are converted into ATP, energy is released and used by the cell.

Answer:

When ATP is converted into ADP + P energy is released and used by the cell.

Explanation: ATP contains energy, when a certain part breaks off it converts into ADP and releases energy for the cell tp use.

When ATP is converted into ADP + Pi , energy is released and used by the cell is the most accurately describes the role of ATP as a source of energy.

What is ATP?

An organic substance called adenosine triphosphate (ATP) gives energy to a variety of biological functions in living cells, including muscular contraction, nerve impulse transmission, condensate dissolving, and chemical synthesis.

ATP is frequently referred to as the "molecular unit of currency" of intracellular energy transfer and is present in all known forms of life. It either transforms into adenosine monophosphate (AMP) or adenosine diphosphate (ADP) when absorbed in metabolic activities (AMP).

ATP is replenished by other processes. Every day, the human body recycles the equivalent amount of ATP to its own body weight. Additionally, it serves as a coenzyme and a precursor to DNA and RNA.

Therefore, When ATP is converted into ADP + Pi , energy is released and used by the cell is the most accurately describes the role of ATP as a source of energy.

Carbohydrates have chemical bonds that are a good source of energy for living things. A monosaccharide is a carbohydrate made by plants when energy from the sun combines water and carbon dioxide.
How are the two other types of carbohydrates formed? Give examples of each type.

Answers

Explanation:

The other two types of carbohydrates, disaccharides and polysaccharides, are formed when monosaccharides link together to form larger molecules and chains. A disaccharide is a sugar that is made from two monosaccharides (di=two). For example, sucrose is a disaccharide that is made from the bonding of glucose with fructose, which are both monosaccharides. Sucrose is known as table sugar, and is found naturally in plants. Polysaccharides are large, complex molecules that are formed when monosaccharides or disaccharides link together in repeating units to form long chains. The most abundant polysaccharide in the world is cellulose, the substance that makes up the cell wall of plant cells. Starches are also examples of polysaccharides, and these are stored in plants such as grains, corn and wheat.

All living organisms must obtain energy in order to survive, and most organisms rely on carbohydrates as energy sources. These molecules are made through the process of photosynthesis, and they store the sun's energy within them.

If a rock falls and kills 10 individuals from a population of 100 plants of the same species and the frequency of alleles changes, does the population evolve instantly from that stochastic event? Can it be said that Natural Selection is at work in this case? And how does the Synthetic Theory of Evolution help answer this question?

Answers

Answer:

Explanation:

This question seeks to test the knowledge of the modern synthetic theory of evolution. This theory describes evolution as the changes occurring in the allele frequency within a population of the same specie. Hence, the following questions derived from the question can be answered as thus

1) Does the population evolve instantly from that stochastic event?

YES. This is because the frequency of the allele changed.

2) Can it be said that Natural Selection is at work in this case?

YES. The synthetic theory of evolution derives great "evidence" from natural selection because the allele frequency is believed to have changed because of the environmental impact (the rock) and that the next generation will adapt better to such an environment.

3) How does the Synthetic Theory of Evolution help answer this question?

Previously, evolution was believed to occur over several generation which ultimately lead to some phenotypic changes as a result of adaptive changes in the genes. This old description of evolution would have made one arrive at a wrong answer if one does not consider the modern synthetic theory of evolution which talks about instant evolution from allele frequency (as was described in the question).

Wild food chain shows who eats whom. Every living thing—from algae to blue whales—needs food. Each food chain is an energy and nutrient channel in the ecosystem.

In food chains, organisms are categorised into trophic levels. Producers (first trophic level), consumers (second, third, and fourth trophic levels), and decomposers roughly correspond to these levels.

Autotrophs produce their own nourishment. They start every food chain. Plants and single-celled creatures are autotrophs. Nearly all autotrophs make "food" (glucose) from sunlight, carbon dioxide, and water through photosynthesis.
