What’s the answer???? This is biology.

Answer:

Organic compounds are compounds which contain carbon and hydrogen covalently bonded to each other and other elements, most notably oxygen, nitrogen, etc.

In this case, the first compound (ethanol, C₂H₅OH) is an organic compound.

Inorganic compounds are any compound which cannot be classified as an organic compound (meaning they lack carbon-hydrogen bonds).

In this case, the second molecule (carbon dioxide, CO₂) is an inorganic compound.

Elements are substances that cannot be broken down and contain a unique amount of protons. Sometimes, elements exist as diatoms in nature (two atoms of the same element).

In this case, the third substance (H₂) is an element.

organic

Explanation:

These organic nutrients move up through the food chain. However, when death occurs, decomposition returns the nutrients to the earth.

Answer:

Lipids (eg cholesterol, cholesteryl esters and triglycerides) are stored in your body primarily in specialized fat cells called adipocytes, which comprise a specialized fatty tissue called adipose tissue. Stored lipids can be derived from the lipids in your diet or from lipids that your body synthesizes.

Answer: C, capillary action.

Explanation:

A straw works because when you suck the air out of the straw, it creates a vacuum. This causes a decrease in air pressure on the inside of the straw. Since the atmospheric pressure is greater on the outside of the straw, liquid is forced into and up the straw and into your mouth.

Answer: A nucleus is basically the brain of the cell. It is in the center of the cell and surrounded by a membrane. The nucleus contains all the chromosomes and controls the cell's growth and reproduction of the cell.

Chlorophyll, a pigment found in chloroplasts, is what allows plants to prepare food through photosynthesis. There would not have been any plant life if there were no chloroplasts.

Chlorophyll, which is found in chloroplasts, traps light and aids in photosynthesis. Without chlorophyll, there would be no food, which would mean no life. We wouldn't have food if plants lacked chloroplasts since they couldn't use the sun's energy to stay alive. On the other hand, mammals would not have enough cellular energy and would not be able to exist without mitochondria. The process of photosynthesis is carried out by some plants that lack chloroplasts.

Answer:

the difference is that a normal DNA sequence is stronger than a sickle cell DNA

Explanation:

There are two condition: -

1. Less offspring, and more parenting

2. More offspring and less parenting

Less children and more parenting have the advantage of requiring less energy for reproduction and more for parenting, which eliminates the possibility of infant death. The drawback is that this results in a relatively small number of progeny, who may be eliminated by the environment, enemies, or predators, causing disruption in population.

The benefit of having more children and doing less parenting is that there will be a huge amount of children generated who are capable of reproducing, which will ultimately lead to population expansion. The drawback of this situation is that there is no guarantee of survival because of the possibility of encountering predators, natural disasters, or other challenges.

We never see reptiles during extreme winter because they are unable to control body temperature and hibernation is a behavioral adaptation associated with to the unequivocal presence of changes in the behavior of an animal to adapt to extreme cold conditions.

Behavioral adaptation is a type of adaptation in which organism change their behavioral features to adapt to challenging environmental conditions such as extreme cold conditions in the case of animals that hibernate during the winter.

This type of adaptive mechanism (behavioral adaptation) is fundamental to maintaining the homeostatic equilibrium in adverse conditions.

In conclusion, we never see frogs, snakes and lizards during extreme winter because they are unable to control body temperature and hibernation is a type of adaptation called behavioral adaptation due to the presence of changes in the behavior of an animal to adapt to extreme cold conditions.

Dormancy is the period during which the organism's metabolism decreases to conserve energy. Hibernation is a type of dormancy expressed by animals. This adaptation is Hibernation.

Dormancy is a period in the metabolism of different organisms, in which their growth, development, and physical activity get suspended for some time. The reduction in all metabolic activities allows the organism to conserve its energy.

Dormancy is closely related to environmental conditions and is considered an adaptation mechanism by which organisms respond to extreme conditions.

Hibernation is a type of dormancy, in which animals progressively decrease their metabolic rates, and body temperature is held a few degrees over the ambient temperature. During hibernation, all functions are reduced: cardiac rithm, respiration, renal function, etcetera.

Frogs, snakes, and lizards, among other cold-blooded animals, need to go through dormancy to survive extremely cold temperatures.

Notice that the dormancy term is commonly used in seeds when referring to the period before they germinate and the new plant emerges. This is another type of dormancy that relates especially to plants.

This type of adaptation is Hibernation (or animal Dormancy).

A hypothesis outlines your expectations for the results of your investigation. It is a speculative, untested response to your research question. You might need to develop a number of hypotheses for some research projects that speak to various facets of your research issue.

A hypothesis should be founded on accepted ideas and body of information; it shouldn't just be a wild guess. Additionally, it must be testable so that you can use scientific research techniques to either confirm or disprove it (such as experiments, observations and statistical analysis of data). A relationship between two or more variables is proposed by a hypothesis. Anything the researcher modifies or controls is referred to as an independent variable. An observation or measurement made by the researcher is a dependent variable.

Answer: Organism 4 is a eukaryotic cell because the organism is missing a cell wall.

Prokaryotic cells do not have membrane-bound organelles (so no nucleus, the DNA is free-floating), and have cell walls.

Eukaryotic cells have no cell wall, contain membrane-bound organelles (so they have a nucleus), and the DNA is kept inside the nucleus.

Titration is a useful tool in the determination of amino acid side chains and the ionizable groups. There are two titratable groups for the unknown amino acid. These are α-COOH and α-NH₃⁺. The experimental pKa values for the groups are- pK₁ = 2.35 for α-COOH and pK₂ = 9.78 for α-NH₃⁺.

Amino acids are the organic compounds that contain both amino and carboxylic acid functional groups. Isoelectric point (pI) is the pH at which the net charge on an amino acid is zero. The isoelectric point of the given amino acid can be calculated by the formula:

pI = (pK1+pK2)/2 = (2.35+9.78)/2 = 6.065

Isoelectric point will be in the middle part of the curve in the buffer region. Buffer region is the section of curve between the initial point and the equivalence point.

The unknown acid would be glycine. The curve gas two dissociation steps- loss of H⁺ from the carboxyl group at low pKa value and gain of H⁺ by the amino group at high pKa value.

Answer: One reason is the Co2 (Carbon Dioxide) in the air may cause the algae growth.

Explanation:

Carbon dioxide has been known to cause excessive blue or green algae.

The parameters in the equation are;

y = volume of the tank

5 = The rate at which water is leaving the tank

m = the number of minutes the water has been flowing into the tank

48 = The initial volume of the tank.

We know that a function is a Mathematical rule. We can understand that the function is that which gives us an idea of the kind of operation that we ought to perform as shown. Now we have the information that  the volume of water in a water tank can be represented as 48 more than the product of 5 and m, where m represents the number of minutes the water has been flowing into the tank.

If we want to write this as an algebraic equation we are going to have written this sort as shown below as; y = 5m + 48. We can see that this looks exactly like the equation of a straight line graph;

y = volume of the tank
