How much the human know the sea​

Answer:

The answer is Aphid, Bird, and Rabbit.

Species change gradually and consistenly over a very long period of time. This is known as species adaptation. Thus, the correct option is D.

Species do not undergo drastic changes over a short period of time, rather it is a gradual change which occurs. These changes accumulate over a long period of time.

The changes are a result of modifications in the phenotype due to the mutations in the genotype. These mutations occur for better adaptation to the changing environment for the survival of the species.

Thus, the change that is seen in the bivalves has occurred over a long period of time gradually for adapting to the environment in a way that facilitates survival of the bivalves shown in the diagram.

Answer:

Sexual selection.

Explanation:

Female finches, which do not sing, tend to choose to mate with males that sing a specific, elaborate song. This is an example of sexual selection.

Sexual selection is “natural selection arising through preference by one sex for certain characteristics in individuals of the other sex.”

The stirrup is a part of the middle ear. The correct option is B

The loudness of a sound depends on its intensity. The correct option is B.

The blending of fundamental tones and overtones produces a sound's timbre.

The correct option is C.

The stirrup or stapes is one of the three bones of the middle ear attached to the membrane-covered opening that connects the middle ear with the inner ear.

The loudness of a sound that is perceived by the ear depends on the amplitude of the vibration producing the sound which in turn is proportional to the intensity.

Explanation:

Alright, buckle up, since this isn't your average "the answer is C" explanation. Sorry beforehand for this upcoming essay. To make this easier, I'll give out the answers to start and then leave a "Why?" portion in case you want an in-depth explanation. I recommend getting the answers first since I can tell you're in a hurry, but if you get the chance look over a thing or two I said. Now:

To start, the 4 genotypes for the Dark Gray Rabbit are DD, Dd\(^{ch}\), Dd\(^h\), and Dd.

Why? Well, we know Dark Gray is dominant to all other alleles, so a Dark Gray allele with any other allele will produce a Dark Gray Rabbit.

The same concept above applies to the other rabbits:

The Chinchilla rabbit is d\(^{ch}\)d\(^{ch}\), d\(^{ch}\)d\(^h\), and d\(^{ch}\)d.

The Himalayan rabbit is d\(^h\)d\(^h\) and d\(^h\)d.

The Albino rabbit is dd.

Part 2:

Chinchilla Rabbit

Why? Because you have 2 Chinchilla alleles, and since they don't dominate and aren't dominated by any other allele, the rabbit will be a Chinchilla Rabbit.

Dark Gray Rabbit

Why? Same rule of dominance, and plus, it was one of the phenotypes listed in the first question.

For the table, look at the help image.

And finally, for the plan, the first set of rabbits with have a 50% chance of producing a dd\(^h\) rabbit, which is a Himalayan rabbit. Then, breeding two of these will ALWAYS give you a Himalayan rabbit.

Why? Because the only alleles are d and d\(^h\), and since d\(^h\) is always dominant of d, there will never be a case where that rabbit is albino (thus always Himalayan)

Hope you got it all down, and glad I could be of any service.

Wind is the natural resource which is renewable. Therefore, option (B) is correct.

Wind energy is considered a renewable resource because it comes from the natural flow of air masses caused by the sun and the Earth's rotation. Wind turbines turn the kinetic energy of the wind into power, and as long as there is wind, this process can keep going forever.

Wind doesn't run out like coal and oil (options A and D), which are both solid fuels. Topsoil (choice C) is an important resource for agriculture, but it can be worn down or eroded over time, making it non-renewable in the short run if it is not managed well.

Answer:

The term "weather" means the state of the atmosphere in a shorter period of time, while the term "climate" refers to how the atmosphere behaves in the long run.

Explanation:

When we talk about climate change, we are talking about long-term change.

"tTme" describes the way in which the atmosphere "behaves", which primarily means the effects that this "behavior" has on life. The biggest difference between climate and weather is that the term "weather" refers to extremely short-term changes in the atmosphere - so short that they are measured in minutes and months.

The statement that a certain amount of kinetic energy is required to break the bonds between atoms and make a chemical reaction go is not entirely accurate.

The rephrased statement is:

For a chemical reaction to occur, a minimum amount of energy, called the activation energy, is required to break the bonds between atoms in the reactant molecules, and the likelihood of a reaction occurring increases with the number of molecules with sufficient energy to overcome the activation barrier."

A chemical bond is a strong attraction between atoms or ions that allows molecules and crystals to form. Ionic bonds and covalent bonds both form when two oppositely charged ions interact electrostatically.

For a chemical reaction to occur, a minimum amount of energy, called activation energy, is required to break the bonds between atoms in the reactant molecules. This activation energy can come from a variety of sources, including heat, light, or catalysts, and it is often provided by the thermal energy of the surroundings.

However, it is not true that if the molecules do not have at least that energy, then there will be no reaction within the substance at all. In reality, there will always be some molecules with enough energy to undergo a reaction, even at lower temperatures, due to the statistical distribution of kinetic energies among molecules.

Answer:

NAD+ (nicotinamide adenine dinucleotide) is indeed crucial for ATP production, even in anaerobic pathways such as glycolysis followed by fermentation. Allow me to explain the significance of NAD+ and its role in ATP production.

During glycolysis, glucose is broken down into pyruvate, producing a small amount of ATP and NADH. The conversion of NAD+ to NADH occurs during the oxidation of certain molecules, including glucose, in the pathway. This conversion is essential because NADH carries high-energy electrons that can be used in subsequent steps to generate more ATP.

In aerobic respiration, NADH is further utilized in the electron transport chain (ETC) within the mitochondria. The ETC transfers electrons from NADH to oxygen, generating a significant amount of ATP through oxidative phosphorylation. However, in anaerobic conditions where oxygen is limited, like during fermentation, the ETC cannot function.

Here's where NAD+ becomes critical. In order to keep glycolysis running and continue generating ATP, the NADH produced during glycolysis must be converted back to NAD+. This allows glycolysis to continue producing ATP, even without the presence of oxygen. Without a mechanism to regenerate NAD+, glycolysis would halt due to a lack of NAD+, leading to a severe reduction in ATP production.

Fermentation pathways differ depending on the organism, but they all involve the regeneration of NAD+. For example, in lactic acid fermentation, pyruvate is converted into lactate, which involves the transfer of electrons from NADH to pyruvate, regenerating NAD+. Similarly, in alcoholic fermentation, pyruvate is converted into ethanol, again regenerating NAD+.

In summary, NAD+ is essential in anaerobic ATP production because it serves as a coenzyme that accepts electrons and facilitates the conversion of NADH back to NAD+. By regenerating NAD+, cells can sustain glycolysis and continue producing ATP, even in the absence of oxygen.
