Tiger is a top predator in the jungles of Asia and the goldfish is a small species of fish selectively bred in China and they are not at all related.

All living things have the same way of transferring genetic information, trough the DNA molecule. Genetic analyses showed that the last common ancestor (LUCA) of all organisms on Earth has lived 3,5 billion years ago. After that, all living things diverged into separate groups. Tigers and goldfish both are animals and have a common ancestor. Tigers may be in a close relationship with other big cats like lions and cheetahs, but they all have a common ancestor with the goldfish since all vertebrates have a common ancestor that was an ancient fish species.

Answer:

Energy is absorbed

Explanation:

The phosphate bonds of ATP are high energy bonds. One phosphate bond can have an energy of ΔG of -30.5 kJ/mol. This is why ATP is an ideal energy molecule for cells because they preserve the energy of cellular respiration, derived from energy molecules, into their bonds. Later the energy can be harnessed when the ATP is hydrolyzed in a  biochemical reaction.

ATP+H2O→ADP+Pi ΔG = -30.5 kJ/mol

ATP+H2O→AMP+2Pi ΔG = -61 kJ/mol

2ADP+H2O→2AMP+2Pi ΔG = -61 kJ/mol

Yorkshire Terrier and the Shi Zu. I have heard

Dogs like the Xoloitzcuintli, which is a hairless breed, have hypoallergenic coats. However, breeds like Labrador Retrievers have dense double coats that can trap allergens. It's always best to spend time with a breed before bringing it home if there's a potential allergy concern.

Some dogs have a hypoallergenic coat, which means they are less likely to cause an allergic reaction in people sensitive to dander. For instance, the Xoloitzcuintli, a hairless dog first bred in Mexico, has this type of coat. Its lack of fur reduces dander, a common allergen. However, hypoallergenic does not mean allergen-free; individuals may still react if they are extremely sensitive.

On the other hand, breeds like Labrador Retrievers have dense double coats that can trap dander, making them not ideal for those with allergies.

However, individual reactions can vary greatly, and it's always best to spend time with a breed before bringing it home, particularly if it's being introduced to an allergy-prone household.

The method to find the optimum pH for catalase activity involves testing the enzyme activity at various pH levels and measuring the rate of reaction.

To determine the optimum pH for catalase activity, prepare a series of buffer solutions with different pH values ranging from acidic to basic. Use these buffers to create reaction mixtures containing the same concentration of catalase and its substrate, hydrogen peroxide (H₂O₂).

Measure the rate of oxygen production, which indicates catalase activity, using a gas syringe or a manometer. Plot the rate of reaction against the pH values. The pH at which the reaction rate is highest is the optimum pH for catalase activity.

Ensure to replicate each experiment to account for any variability and confirm the results for accuracy. This method allows for precise identification of the pH condition where catalase performs most efficiently.

Sexual reproduction in a species usually results in genetic variation.

This is because the two parents that contribute to the offspring share only some of their genes. The offspring will therefore have a unique combination of genes that is different from either parent.

Genetic variation is important for a species because it allows the species to adapt to changes in the environment. If the environment changes, some individuals in the species may have genes that allow them to survive and reproduce in the new environment. These individuals will pass on their genes to their offspring, and the species will gradually adapt to the new environment.

Organisms like corals and shellfish use carbon by forming calcium carbonate (CaCO3) from calcium (Ca2+) and carbonate (CO32−) ions in seawater. This substance is what makes up their hard, protective shells and skeletons.

The process through which organisms like corals and shellfish build their shells is known as calcification. It involves the combination of calcium ions, which are abundant in seawater, with carbonate ions to form calcium carbonate. This calcium carbonate then gets deposited to form the hard external shells of shellfish or the exoskeleton of corals. In corals, symbiotic algae, known as zooxanthellae, play a vital role by contributing to carbon fixation through photosynthesis, which provides the necessary carbonate ions for this process. Similarly, other marine calcifying organisms like coccolithophores and foraminifera use the abundant bicarbonate ions in the ocean to contribute to the formation of marine sediments, which over time can become limestone, a significant carbon reservoir.

In Tony's experiment, the plant was undergoing respiration in the dark for 24 hours, absorbing oxygen and releasing carbon dioxide. This would lead to a decrease in oxygen concentration and an increase in carbon dioxide concentration in the jar.

In Tony's experiment, the potted plant enclosed inside a bell jar was subject to a process called photosynthesis during the day and respiration during the evening. During photosynthesis, plants absorb carbon dioxide (CO2) and release oxygen (O2) to the environment. In contrast, during the respiration process, plants absorb O2 and release CO2, a process which continues even during the night. Considering the setup of Tony's experiment, the plant was in darkness for 24 hours, which means it was only undergoing respiration.

Based on these factors, the correct statement describing the measurements Tony would find in the jar is: Oxygen concentration decreased, carbon dioxide concentration increased. This is simply because, during respiration, the plant would be using up the available oxygen and releasing more carbon dioxide in the sealed jar, leading to a decrease in oxygen concentration and an increase in carbon dioxide concentration. This change would be relative to the initial measurements in the classroom environment.

They build more houses and more factories to produce more goods for the population also including more vehicles for more income of people buying them. Stores and etc.

Answer:

Built more houses to live, construct more factories to produce more

Explanation:

Population growth is a serious problem in today's scenario. The growing population demands more food and more land for their needs. As it increases, more land is used for building houses and factories. The advanced technology helps people to grow more food from a small piece of land. It causes the sterility of the land along with air pollution, as more chemical fertilisers are used. Due to increasing population migration occurs, which also reduces the landmass of different areas.

A wave that carries a large amount of energy will have a large amplitude, with its energy being proportional to the amplitude squared. Larger E-fields and B-fields in electromagnetic waves also indicate a greater energy content. High-frequency waves carry more energy compared to low-frequency waves.

A wave that carries a large amount of energy will always have a large amplitude. The energy carried by a wave is proportional to the amplitude squared. This means that a wave with twice the amplitude of another will carry four times as much energy. The energy density of a wave is also affected by the medium it travels through, and the energy flux, which is related to this density, depends on both this energy density and the wave's speed. In the case of electromagnetic waves, for instance, larger E-fields and B-fields indicate higher energy content due to the larger forces they can exert.

High-frequency waves also carry more energy, as demonstrated by waves in the electromagnetic spectrum like X-rays and UV rays, which can penetrate tissues and damage cells due to their higher energy content. This correlates with the concept that energy transfer is higher when the force involved is greater. Consequently, larger waves or waves with higher frequency will always carry more energy than smaller waves or waves with lower frequencies.

Answer:

Zero (0) chances

Explanation:

Hemophilia is a sex-linked disorder.  Meaning that male offspring are more predisposed to inheriting the disorder than female offspring. This is because the male is XY while the female is XX. The Y chromosome carries very few genes, therefore, is the allele for the disorder on the X chromosome are recessive, it is likely that they will develop the disorder. This is unlike the female who has an extra X chromosome that has the working gene if the other X chromosome has a defective gene.

Bright colors are difficult to see in a room lit by candles because the spectral composition of candlelight is heavily weighted towards the longer wavelengths of the visible spectrum, which are perceived as yellow and red. This results in a reduced visibility of colors that require a broader spectrum of light, particularly those with shorter wavelengths like bright blues and greens, to be seen accurately.

To understand this, let's delve into the nature of light and color perception. Color vision relies on the detection of different wavelengths of light by the photoreceptor cells in the retina, known as cones. There are three types of cones, each sensitive to different ranges of wavelengths corresponding to blue, green, and red light. The brain interprets the signals from these cones to perceive a wide range of colors.

Candlelight, however, does not emit light evenly across all wavelengths. It is deficient in the shorter wavelengths (blue and green parts of the spectrum) and has a greater intensity in the longer wavelengths (yellow and red parts of the spectrum). This imbalance means that objects reflecting light primarily in the blue and green regions will not be as stimulating to the cones responsible for detecting those colors, making it harder to distinguish them.

In contrast, colors that reflect the yellow and red wavelengths, which are more abundant in candlelight, will be easier to see. This is why warm colors like oranges, reds, and yellows may appear more vivid under candlelight, while cooler colors such as blues and greens can seem dull or even black.

The correct answer is D. Decrease in soil fertility.

A particular crop has a particular need for certain nutrients, and contributes a certain set of nutrients in return to the soil. When the same crop is planted over and over the years, the certain set of nutrients required to sustain are used up, and an accumulation of particular nutrients not essential for that particular plant's growth piles up. This leads to poor growth and development of the plant due to nutrient deficiency - and the quality of a soil to sustain growth and agriculture of a plant is known as fertility, which in this case decreases.

Answer:

decrease in the fertility soil

Explanation:

Answer:

First, you chew the bread in your mouth which contains complex carbohydrates like starch and cellulose. In your mouth, your salivary glands are specialised cells in glands to produce a carbohydrase enzyme like amylase in your saliva. Amylase partially breaks down carbohydrates like starch which is a big food molecule that cannot be digested. It breaks down into a smaller molecule that can be digested into maltose. This is carried out by a process like the lock and key theory. The enzyme, amylase has an active site where the substrate, in this case being the carbohydrate, binds to the enzyme because it fits the certain shape. The reaction then takes place rapidly as the substrate is catalysed. Products are released from the surface of the enzyme because it breaks up the large molecule into smaller ones and the enzyme is ready to be used again.

The partially broken up food then travels down your gullet and into the stomach where it's lined with millions of glands that produce the enzyme, pepsin and hydrochloric acid. The right pH levels are needed for the enzymes to work best in like pepsin (pepsin breaks down proteins and not carbohydrates) but hydrochloric acid kills bacteria in the food.

Some enzymes that catalyse digestion are made in the pancreas, like amylase. The pancreas secretes the digestive juices onto the food which breaks it down further. Depending on the size and type of meal, the food then leaves your stomach and moves onto the small intestine. As it moves into the small intestine, bile (which is produced in the liver) is squirted onto the food through the bile duct. The bile neutralises the acid that was added to the food by the stomach. This provides the alkaline conditions necessary for the enzymes in the small intestine to work most effectively.

The food then travels through the small intestine where amylase further breaks down the food molecules into smaller, soluble ones which can be absorbed into your bloodstream. The small intestine is adapted to have a very large surface area and is covered in villi. Villi are adapted to have large surface area and are only one cell thick  so nutrients only have a short distance to diffuse into the blood. It also has a good blood supply to the blood vessels. This greatly increases diffusion and active transport from the small intestine to the blood.

Finally the muscular walls of the small intestine squeeze the undigested food into the large intestine. water is absorbed from the undigested food into your blood. The material left forms the faeces. Faeces are stored and then pass out of your body through the rectum and anus back into the environment.

Explanation:

Bread mainly contains carbohydrates. Hence, they are converted into monosaccharides for absorption.

Digestion of carbohydrates starts from the mouth. After chewing and converting into small particles, it gets mixed with the salivary amylase enzyme present in the saliva. Then it reaches the stomach and then the small intestine where pancreatic amylase breaks down carbohydrates into disaccharides.

These disaccharides break down into monosaccharides by enzymes present in intestinal juice, such as sucrase breaking down sucrose into glucose and fructose, and maltase breaking down maltose into glucose. Then it is transferred to the bloodstream through the villi.

Hence, this is how carbohydrates are digested in our bodies.
