Answer:

Only 10 percent of energy is transferred from one trophic to another while the elements transfer are proteins, carbohydrates and fats.

Explanation:

The flow of energy occurs in an ecosystem through a number of trophic. From the first trophic level to the second trophic level only 10 percent of energy is transferred while the rest of the energy is released in the form of heat energy. Flow of elements in the ecosystem refers to the elements that are essential for the survival of organism. These elements are present inside the foods which is eaten by these animals. Proteins, carbohydrates and fats are the elements transfer from one organism to another by eating the food.

Explanation:

As requested in the question above, the primers were presented with 8 nucleotides, with the nitrogenous bases of the DNA, and in the 5'-3 'direction.

Primers are small fragments of DNA that are used by DNA polymerase to form new strands. The primes attach to pieces on the ribbon, through the complementarity of the nitrogenous bases, serving as a template for the DNA polymerase to create the new ribbon.

DNA polymerase uses primers at the origin of replication, and can follow the path from the right or from the left, depending on the primers used, for this reason, this question has two answers.

Answer:

c. metallic bond

Explanation:

Metallic bonding, unlike other forms of atomic bonding, involves delocalized elections. The negatively charged electrons form a "sea" around metal cations. Electrons within the valence shells of metals are only held loosely within their molecular orbits- the metals are held together due to the strong attraction between these delocalized electrons and positive nuclei.

The electrons are typically described as mobile, free, and delocalized. These traits are responsible for several metallic properties such as:

Answer:

would increase

Explanation:

C3 plants are those where the first carbon compound produced during photosynthesis have three carbon atoms per molecule (instead of 4 in C4 plants). While higher is temperature and light, oxygen (O2) exhibits a higher affinity for Rubisco, a key enzyme in photosynthesis. In environmental conditions with high temperatures and light such as, for example, Texas when this state is compared to North Dakota, C4 plants tend to be more productive than C3 plants (because these plants have different metabolic pathways). Thus, it is expected that the percentage of C4 plant species in the local grass flora increases as latitude decreases.

It should be noted that the percentage of grass species using the C4 photosynthetic pathway would increase.

It should be noted that C3 plants simply refer to those where the first carbon compound produced during photosynthesis has three carbon atoms per molecule rather than the four carbon atoms that are in C4 plants.

In environments with high temperatures and light such as Texas when this state is compared to North Dakota, C4 plants tend to be more productive than C3 plants. Therefore, it is expected that the percentage of C4 plant species in the local grass flora will increase when there is a reduction in latitude.

A new cell become specialized into a heart cell when its structure can be changed into a heart cell.

When the cell become specialized into heart cell by changing its structure, it will be able to do the function properly. Cell differentiation is that process in which cells become specialized into different types of cells such as heart cell, liver cell etc. A stem cell is an unspecialized cell that change into specialized cells under specific conditions which force the unspecialized cell into specialized cell.

When the heart needs more cells then the stem cells start converting into heart cells by changing its form and structure. These specialized cells go to the place where they are needed the most and start their work so we can conclude that new cell become specialized into a heart cell by changing its structure.

Answer: oxygen

Explanation:

If the process illustrated in the diagram is interrupted by a chemical at point X, there would be an immediate effect on the release of oxygen gas.

Photosynthesis, the process by which light energy is transformed to chemical energy and results in the generation of oxygen and energy-rich organic compounds, takes place in the chloroplast, a structure found inside the cells of plants and green algae.

Close relatives of chloroplasts that are free-living are photosynthetic cyanobacteria; according to the endosymbiotic theory, these organisms are the ancestors of both chloroplasts and mitochondria, which are eukaryotic cells' energy-producing organelles.

Therefore, If the process illustrated in the diagram is interrupted by a chemical at point X, there would be an immediate effect on the release of oxygen gas.

Volcanic eruptions may cause destruction but they also create little islands like Hawaii.

Explanation:

The layers of atmosphere are differentiated on the basis of different temperature gradients.Thus,different layers within the atmosphere are created.

Toposphere is heated from the ground. Thus, with increase in altitude temperature decreases.

In the stratosphere, temperature increases with altitude. The direct heat source for the stratosphere is the Sun. Air in the stratosphere is stable because warmer, less dense air sits over cooler, denser air.

In Mesosphere temperature decreases with altitude. Few gas molecules present in mesosphere absorb sun's radiation.The heat source is the stratosphere below. The mesosphere is extremely cold, especially at its top, about -90°C.

Thermosphere which also contains ionosphere.The density of molecules is so low in here that one gas molecule could easily go upto 1 km before it collides with another molecule. It is so little energy is transferred, the air feels very cold

Gel matrix

Explanation:

Gel electrophoresis is a technique in molecular biology used to separate fragments of biomolecules such as DNA, RNA, protein by applying electric current through a GEL medium. The basis of separation of this fragments is their sizes and electrical charge.

In the gel electrophoresis procedure, a GEL medium made of Agarose is used. The DNA fragments, which are then negatively charged begins to move towards the positive end of the gel when electric current is supplied. The smaller fragments move/migrate faster than the larger ones towards the positive end. Therefore, In gel electrophoresis, fragments are separated by size and electrical charge by applying GEL to them.

Answer:

Air masses build when the air stagnates over a region for several days/weeks. To move these huge regions of air, the weather pattern needs to change to allow the air mass to move. One major influence of air mass movement is the upper level winds such as the upper level winds associated with the jet stream.

Explanation:

A major cause for moving air masses in North America is the upper-level winds.

An air mass refers to a large body of air that has identical conditions throughout. It should be noted that air masses take on the condition of the area where they're formed.

Air masses move due to winds and air currents. Moving air masses bring about changes in the weather.

D: 4.6 x [tex]10^{9}[/tex]

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.

b.cell from a sunflower leaf

The structure that can have chloroplast is the cell from sunflower leaf. The correct option is B.

Chloroplasts are chlorophyll-containing organelles found in plant cells; they are necessary for Earth life because photosynthesis occurs in chloroplasts.

Proplastids give rise to chloroplasts, as do chromoplasts, leucoplasts, as well as other plastids.

Chloroplasts are plant cell organelles that use photosynthetic energy to convert light energy into reasonably stable chemical energy.

They survive life on Earth by doing so. Chloroplasts also perform a variety of metabolic functions for plant cells, such as the generation of fatty acids and membrane lipids.

Chloroplasts are found in all green plants and algae. Chloroplasts can also be found in photosynthesis that don't appear green, such as giant kelp's brown blades or certain plants' red leaves.

Thus, the correct option is B.
