During respiration in plants and animals, carbon dioxide is returned to the environment.

Carbon dioxide is a dull gas with a thickness of about 60% which is higher than that of dry air. Carbon dioxide comprises of a carbon particle covalently twofold attached to two oxygen molecules. It is seen in atmosphere in traces.

When organism such as plant, animals, algae and other microorganism respires, it leads to return of carbon dioxide to the environment as it is the major compound formed due to the metabolic activity in them. Apart from this burning of fossil fuels and deforestation also act as cause of returning of carbon dioxide to the environment.

Explanation:

Their genes determine the traits plus characteristics. Genes determine their eye shade, hair shade, and skin tone. Unlike the other alleles, they are withdrawn and are also much less possible to be expressed in many different ways. A dominant allele is also forced to be paired up with another recessive allele. Which also means that the most dominant and strongest allele is going to determine the characteristics by one hundred percent to one hundred percent.

Obsidian is formed when rapidly cooling ions are randomly distributed creating a a. glassy texture.

Obsidian is a type of mineraloid, which is formed when liquid content of the volcanic material cools so quickly that particle lacks ability to transform into a crystalline structure. The outcome is a volcanic glass with a smooth uniform surface that breaks with a conchoidal crack.  

As a “glass”, obsidian is artificially shaky. With the progression of time, some obsidian starts to solidify. This procedure doesn't occur at a uniform rate all through the stone. Rather it starts at different areas inside the stone. In these areas, the crystallization procedure structures spiral groups of white or dim cristobalite gems inside the obsidian. Whenever cut and cleaned, these examples are alluded to as “snowflake obsidian”.

Answer:

Flagella and cilia

Explanation:

Two of the organelles that are involved in the movement of a cell in its environment are the flagella and the cilia. Flagella can be described as a long structure shaping whip like which helps in the movement of single celled organisms. Like its structure, the cause the movement of the organism to be whip like. An "S" type motion is observed through the flagella present in the eukaryotes. Cilia is an organelle that can either be motile or non motile. Motile cilia take advantage of their cytoskeleton for movement.

Final answer:

Cilia and flagella are the organelles involved in cell movement, possessing a 9+2 microtubule structure and motor proteins dynein and kinesin for motion.

Explanation:

The two organelles involved in the movement of a cell in its environment are cilia and flagella. Both these structures are critical for cell motility and are found in eukaryotic cells. They have a structural basis called the axoneme, consisting of 9 microtubule doublets arranged in a circle around a pair of single microtubules (2X9+2 structure), and utilize motor proteins, dynein and kinesin, for their movement.

Cilia are relatively short and often cover the cell surface where they work synchronously to move the cell or to move fluid and particles across the cell surface. Flagella are usually much longer and propel the cell with a whiplike motion. In both cases, the sliding of microtubules against each other, driven by the motor proteins, results in either rowing or undulating movements that allow the cell to navigate its environment.

c. codominant with the allele for the white flower color

Explanation:

i meant this one sorry

Based on typical patterns in plant genetics, the allele for purple flower color in the plant shown would likely be dominant over the allele for the white flower color. This is supported by Mendel's law of dominance and demonstrated through the Punnett square approach.

In relation to your question about the plant shown and the color of its flowers, the allele for purple flower color is likely dominant to the allele for the white flower color. To clarify, this is supported by Mendel's law of dominance, which indicates that in a heterozygote (a plant with one dominant and one recessive allele, like Vv), the dominant trait will be the one expressed.

Hence, as per the information from numerous studies, purple is often the dominant trait over white in flower color for many plant species, including peas.

Apart from that, from the Punnett square approach, when a homozygous dominant plant (VV) is crossed with a homozygous recessive (vv), all offspring in the first generation (F1) will be heterozygous (Vv) and will show the dominant trait, which in this case is the purple color.

In conclusion, based on this established genetic principle, if the plant you are referring to exhibits this common genetic pattern, then the allele for purple flower color would be dominant to the white flower color.

D. The height increases

Beach is the place in which we can enjoy the waves. It is a surprising phenomenon which all loves to watch. As the waves arises in the sea, the wavelength of the waves keep on decreasing from the mid of the sea till the shore. Due to this, the crest of the wave which emerged from the center of the sea has high distance when compared to the wave which has neared the shore.  

As the waves moves towards the shore from the mid of the sea, the height of the wave increase and it hits the shore and moves back.

Answer:

gumlike material from cone bearing trees

Amber is the fossilized sap of coniferous trees that sometimes contains inclusions like insects and is used for aesthetic and purported therapeutic purposes. It is a gumlike material, not related to the tree's bark or needles, and has gained cultural recognition through media like Jurassic Park.

Amber is the fossilized sap of coniferous trees, specifically from the group known as gymnosperms. Over millions of years, this sap hardens and is preserved in the geological record as amber, often containing inclusions such as air bubbles or insects that became trapped when the sap was still sticky. This biological process is distinct from the materials that make up the needles, bark, or cones of the tree, which do not typically fossilize into amber. Hence, amber is a gumlike material from cone-bearing trees. It is valued both for its scientific significance and its aesthetic appeal when polished for jewelry. Additionally, some believe amber has therapeutic properties, such as providing pain relief, though this is not scientifically substantiated. While amber is prominently known due to its fictional portrayal in the Jurassic Park film series, the reality of extracting dinosaur DNA from amber-encased insects remains purely science fiction.

How Does Food Complexity Affect the Biodiversity of an Ecosystem? -More consistency among populations, but still changing through time. As food web complexity increases, there is less stability in the population of the different species, causing as a result, biodiversity fluctuations in a more rapid and frequent way.

The complexity of a food web is directly proportional to the biodiversity of an ecosystem. More complex food webs with multiple levels of consumers and producers can support a higher number of species. In contrast, simpler food webs might not enable such high biodiversity.

The complexity of a food web greatly affects the biodiversity within an ecosystem. A complex food web with multiple levels of consumers and producers can support a higher number of species as there are more niches, or roles, available. This can result in greater diversity and stability. For example, in a complex aquatic ecosystem, there might be multiple types of algae (the producers), various small invertebrates that eat the algae, fish that eat the invertebrates, and birds that eat the fish. Each level of the food web supports the others and allows for a diverse array of species to coexist. In contrast, a simple food web with few producers and consumers might not be able to support such a high level of biodiversity.

Nervous

Explanation:

It is the study of the nervous system's function.

Answer:nervous

Explanation:

Among the given options, the 'duration of protein' does not contribute to a protein's structural organization. Factors like temperature, pH, and amino acid sequence do play a significant role. They directly impact how a protein's structure forms and changes, which in turn influences a protein's function.

The level of organization within a protein is influenced by several factors, including temperature, pH, and amino acid sequence. However, the 'duration of protein' does not contribute to a protein's structural organization. Proteins are organized in four levels: primary (unique sequence of amino acids), secondary (local folding into structures like a-helix and B-pleated sheet), tertiary (overall three-dimensional structure), and sometimes quaternary (when multiple polypeptides combine).

Changes in temperature or pH can cause changes in the protein's shape or denaturation, leading to loss in function. In contrast, the amino acid sequence is crucial in determining the protein's basic structure.

Temperature, pH, and amino acid sequence significantly influence the structure and function of a protein. However, the 'duration of protein' doesn't affect the level of organization within a protein. Proteins do not possess an inherent lifespan that impacts their function or structure. Therefore, the correct answer is option 4-Duration of protein.

The level of organization within a protein is largely influenced by factors such as temperature, pH, and amino acid sequence. These influence the protein's primary structure (the unique sequence of amino acids), secondary structure (local folding of the polypeptide), tertiary structure (the overall three-dimensional structure), and optional quaternary structure (when two or more polypeptides combine to form the complete protein structure).

However, the duration of the protein would not contribute to the level of organization within a protein. Proteins do not have an intrinsic 'lifetime' or duration that influences their structure or function. If the structure of a protein is altered, this may lead to a loss in function, a process known as denaturation.

Explanation:

Cells that have differentiated to perform a specific function make up a tissue, tissues of a specific function make up an organ, and organs that coordinate to perform one or more functions make up an organ system. Another organ system is the digestive system made up of organs such as the esophagus, ileum, and stomach. The organs are made up of many tissues types like the muscle tissue that is made of smooth muscle cells.

Explanation:

Answer:

In order to be useful in treating human infections, antibiotics must selectively target bacteria for eradication and not the cells of its human host. Indeed, modern antibiotics act either on processes that are unique to bacteria--such as the synthesis of cell walls or folic acid--or on bacterium-specific targets within processes that are common to both bacterium and human cells, including protein or DNA replication. Following are some examples.

Most bacteria produce a cell wall that is composed partly of a macromolecule called peptidoglycan, itself made up of amino sugars and short peptides. Human cells do not make or need peptidoglycan. Penicillin, one of the first antibiotics to be used widely, prevents the final cross-linking step, or transpeptidation, in assembly of this macromolecule. The result is a very fragile cell wall that bursts, killing the bacterium. No harm comes to the human host because penicillin does not inhibit any biochemical process that goes on within us.

B & D

Explanation:

What differs between the isotopes of an element is the mass number (which is the number indicated after the name of the element e.g carbon-14). The mass number is the sum of neutrons and protons in the nucleus of the atom. The proton number of an element does not change without changing the element. Usually the proton number is equal to the electron number in a neutral atom of an element. However, the neutron number of an element does change (in most cases) within a slight range giving rise to different isotopes of the element.

Therefore in our case, Carbon-14 has 6 protons and 8 neutrons & Carbon-12 has 6 neutrons and 6 protons.

Answer:

B and D are your answers.

The number of electrons is the same as the number of protons and carbon has 6 protons for answer choice B.

For answer choice D because of the occuring isotopes there are as many nuetrons as protons.

The main impact of raw sewage will be an increase in nutrient concentrations. This will spur growth of algae and also increase the populations of the two primary algae grazers

Dumping raw sewage into a nearshore coral reef will cause immediate and severe damage to the ecosystem, resulting in a decline in biodiversity, health of the coral polyps, species diversity, and an overall reduction in reef size. This can also negatively impact local fisheries and tourism, and threaten the local economy.

The dumping of raw sewage into a nearshore coral reef is expected to have a dramatic and immediate negative impact. Similar to the outcome of dredging certain beaches, this action can cause significant disruption to the biodiversity of the reef, damaging or killing off marine life and especially affecting the sensitive corals themselves. Coral reefs, known to be home to approximately 25% of all marine species, are incredibly sensitive to changes in their environment, such as an increase in pollution levels from sewage or a rise in ocean acidification as a result of increased carbon dioxide concentrations.

Therefore, a graph showing the expected immediate impact of this change would likely depict a sharp decline in the health and biodiversity of the reef ecosystem. This could include metrics like a decrease in the number of healthy coral polyps, a decline in species diversity, or a reduction in overall reef size.

Damage to such ecosystems also has indirect impacts, such as a decrease in local fisheries, a decline in the health of marine life species that rely on the reef for their habitat, and a negative effect on tourism. These changes can, in turn, threaten parts of the local economy that depends on these resources.
