Isovolumic relaxation period or early diastole - End of ventricular contraction to the beginning of the atrial contraction.

The relaxed portion of the cardiac cycle known as diastole is when the heart's chambers are refilled with blood. The relaxing of the atria occurs during atrial diastole, whereas the relaxing of the ventricles occurs during ventricular diastole.

Isovolumic relaxation time is the period of time between the aortic component of the second heart sound and the beginning of filling caused by the opening of the mitral valve in the cardiac cycle.

Explanation:

the plant can change its form

Answer:

It will reach to logistic growth.

Explanation:

The human population will reach  logistic growth if the carrying capacity of that area is maximum because the environment has limited resources which can hold a certain amount of population. Logistic population growth occurs when the growth rate decreases as the population reaches carrying capacity. If the environment has limited resources so that the human population will reach to logistic growth and decrease in population growth increases.

Answer:

a. eukaryotes

b. unicellular

c. autotrophs; heterotrophs

Explanation:

Protists represent a separate kingdom of eukaryotic organisms (ie., organisms whose cells have a nucleus). The most important features of protists include: 1- they are unicellular organisms, 2-contain mitochondria, 3-can be parasites, and 4-generally live in optimal conditions in moist or aquatic environments. In the past, protists were divided into Protozoa (animal-like organisms) and Protophyta (plant-like organisms), which nowadays we know are heterotrophic (also often parasitic) and photosynthetic protists, respectively.

Answer:

The carrying capacity of a plant species expect in the equator is higher as compared to the carrying capacity at high Latitudes. This is due to the equator the plants have more light available, so the ecosystem can give them better conditions to survive and reproduce. Remembering that the carrying capacity is the largest population size an ecosystem can support without degrading itself, in the equator would be higher as it can have better conditions of light, so they would survive and reproduce more and the largest population the ecosystem could support would be higher.

Methionine (AUG)Amino acids can be abbreviated using the first three letters of their name.

Methionine can be abbreviated as Met.

The given RNA sequence is AUGUAACGAUGCGUCGUGGCAUCAUGCUGCGUCAGCGGCGAGUCUGACCCGUCUCUAACAGGACGGCCGGGCGUUGUCGUUGA.

We can use the codon chart to determine the amino acid sequence.

The codon chart is used to determine which amino acid is coded by a particular codon in a strand of DNA/RNA.A codon is a sequence of three nucleotides in DNA or RNA that encodes for a specific amino acid.

Each codon codes for a different amino acid.

For example, the codon AUG codes for the amino acid methionine.

To determine the amino acid sequence, we start reading the RNA strand from the start codon AUG and continue reading until we reach a stop codon (UGA, UAA, or UAG).

Then we write down the amino acid sequence for the codons we read, using the codon chart.

Here, the sequence starts with AUG, which codes for methionine.

After that, the next codon is UAA which is a stop codon, so we can stop.

The amino acid sequence is therefore Methionine. So, the answer would be Methionine (Met).

They became extinct, so they did not exist when the younger rock layers formed. Option D.

The most likely scenario based on the information provided is that the organisms that became fossilized in older rock layers became extinct, and therefore, they did not exist when the younger rock layers formed.

Fossils are the preserved remains or traces of organisms from the past, and they provide valuable insights into the history of life on Earth. The distribution of fossils in rock layers follows the principle of superposition, which states that younger rock layers are deposited on top of older ones.

This implies that the fossils found in older rock layers represent organisms that lived in the past and were preserved through the fossilization process.

If the older rock layers contain fossils of many kinds of organisms that are not found in younger rock layers, it suggests that those organisms no longer existed by the time the younger rock layers formed. The absence of their fossils in younger layers indicates that either the organisms became extinct or their populations shifted to different habitats or regions where their remains were not preserved as fossils.

This phenomenon aligns with the concept of extinction, which is the complete disappearance of a species or a group of organisms. Extinction can occur due to various factors such as environmental changes, competition, predation, or other selective pressures.

Organisms that became extinct would not be present in subsequent rock layers because they were no longer alive or did not have a viable population to leave behind fossil remains.

Therefore, the most reasonable explanation is that the organisms that became fossilized in older rock layers became extinct, and this is why they are not found in younger rock layers. SO Option D is correct.

Cork formation is a type of secondary growth that occurs in the stems and roots of woody plants. Gum formation, on the other hand, is a type of defense mechanism that occurs in response to injury or infection.

Explanation:

Water will flow from the right side of the plasma membrane to the left side of the membrane due to osmosis. Hence, the correct answer is option A.

The molecules move across the cell membrane. Water moves from high concentrations to low concentrations by osmosis. Here, the left side has a 12% salt solution. Out of 100, the salt concentration is 12. The right side has 4%. Out of 100 parts, 4 parts of salt are present. The water concentration is higher on the right side (96 parts ). Hence, the water will move from the right side to the left side by the process of osmosis.

Hence, option A is the correct answer.

In this work, several simulations and analyses are carried out to investigate the feasibility of generating electricity from underwater sea currents at Istanbul Bosphorus Strait. Bosphorus is a natural canal which forms a border between Europe and Asia by connecting Black Sea and Marmara Sea. The differences in elevation and salinity ratios between these two seas cause strong marine currents. Depending on the morphology of the canal the speed of the flow varies and at some specific locations the energy intensity reaches to sufficient levels where electricity generation by marine current turbines becomes economically feasible.

In this study, several simulations are performed for a 10 MW marine turbine farm/cluster whose location is selected by taking into account several factors such as the canal morphology, current speed and passage of vessels. 360 different simulations are performed for 15 different virtual sea states. Similarly, 8 different configurations are analyzed in order to find the optimum spacing between the turbines. Considering the spatial variations in the current speed within the selected region, the analyses are performed for three different flow speeds corresponding to ±10% change in the average value. For each simulation the annual energy yield and cluster efficiency are calculated.

Explanation:

Answer: adenosine triphosphate (ATP), is an energy-carrying molecule found in the cells of all living things. ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.

Explanation: Cells require chemical energy for three general types of tasks: to drive metabolic reactions that would not occur automatically; to transport needed substances across membranes; and to do mechanical work, such as moving muscles. ATP is not a storage molecule for chemical energy; that is the job of carbohydrates, such as glycogen, and fats. When energy is needed by the cell, it is converted from storage molecules into ATP. ATP then serves as a shuttle, delivering energy to places within the cell where energy-consuming activities are taking place. ATP is a nucleotide that consists of three main structures: the nitrogenous base, adenine; the sugar, ribose; and a chain of three phosphate groups bound to ribose. The phosphate tail of ATP is the actual power source that the cell taps. Available energy is contained in the bonds between the phosphates and is released when they are broken, which occurs through the addition of a water molecule (a process called hydrolysis). Usually, only the outer phosphate is removed from ATP to yield energy; when this occurs ATP is converted to adenosine diphosphate (ADP), the form of the nucleotide having only two phosphates. ATP can power cellular processes by transferring a phosphate group to another molecule (a process called phosphorylation). This transfer is carried out by special enzymes that couple the release of energy from ATP to cellular activities that require energy.
