The correct answer is ATP releases energy as a phosphate bond is broken.

ATP (adenosine triphosphate) is converted into ADP (adenosine diphosphate) when a phosphate group is removed from ATP, resulting in the release of energy. This process is known as hydrolysis, where water molecules are used to break the bond between the terminal phosphate group and the rest of the molecule.

During cellular metabolism, ATP serves as the primary energy currency of the cell. When energy is required for various cellular processes, the phosphate bond in ATP is broken by an enzyme called ATPase. This enzymatic hydrolysis reaction cleaves off one of the phosphate groups, resulting in the formation of ADP and an inorganic phosphate molecule (Pi). The released phosphate group is then available to be used in other cellular reactions.

The conversion of ATP to ADP is an essential part of energy metabolism in cells. The energy released during this process is utilized to drive various cellular activities, such as muscle contraction, active transport of molecules across cell membranes, and synthesis of macromolecules. Once ATP is converted to ADP, it can be further hydrolyzed to AMP (adenosine monophosphate) if more energy is needed. Ultimately, the energy stored in ATP is released when the phosphate bond is broken, allowing cells to perform their vital functions.

C. A Scotland Yard investigator did this in the 1830s.

Reason:

In the 1830s, a Scotland Yard detective was among the first to utilize bullet comparisons to capture a culprit.

A Scotland Yard investigator did this in the 1830s. Therefore, option C is correct.

A bullet is a kinetic projectile that is fired from a gun barrel as part of firearm ammunition. The majority of handgun bullets are formed of a lead-antimony alloy contained in a soft brass or copper-plated soft steel jacket, although they can also be made of copper, lead, steel, polymer, rubber, and even wax.

A softer lead core is enclosed in a tougher jacket made of steel or cupronickel in rifle and machine gun bullets. Bullets that penetrate armor have an inner core made of hardened steel.

a. a female reproductive structure

Explanation:

Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.

Basically, there are two (2) methods of reproduction and these are;

I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.

II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.

Antophyte is the division name for flowering plants and they are considered to be the most successful of all the other division of plants in terms of reproduction.

Division Antophyta are classified into two (2) main categories and these includes;

I. Monocot: this group of flowering plants have a single cotyledon. Some examples of monocots are lilies, corns, grasses etc.

II. Dicot: this group of flowering plants have two cotyledon. Some examples of dicots are beans, peas, peanuts, etc.

Basically, fruit production in anthophytes develops from female reproductive structure known as the ovary. Once the ovary is fertilized by a sperm, they ripen into a fruit.

A few techniques that can be used to anchor aquarium plants in substrate for healthy growth includes; Tieing the plant to a rock or piece of driftwood, Using plant weights, Planting the plant in a pot and Using aquarium glue.

Tying the plant to a rock or piece of driftwood: This method works great for plants with rhizomes, like Anubias and Java Fern, as you mentioned.

Planting the plant in a pot: Some plants can do well when planted in pots with their preferred substrate. This is good because it is in a controlled enviroment and you can move plant without disturbing the plant.

plant weights: This method is said to be okay for buoyant plants that tend to float away before their roots can establish. However this can be disadvantagous if the weight is made with lead.

aquarium glue: This can be very effective for certain types of plants. It's important to use a glue that is safe for aquarium use (i.e., cyanoacrylate-based glues).

It would take approximately 6.27 years for a 180g sample of radioactive gold (with a half-life of 2.69 years) to decay to 1/8 its original mass.

The decay of radioactive gold can be modeled by the equation:

N(t) = N₀ * (1/2)^(t / t₁/₂)

where N(t) is the remaining mass at time t, N₀ is the initial mass, t₁/₂ is the half-life, and t is the elapsed time.

In this case, we want to find the time it takes for a 180g sample of radioactive gold to decay to 1/8 its original mass. This means that the remaining mass (N(t)) is 180g / 8 = 22.5g. We can substitute these values into the equation and solve for t:

22.5g = 180g * (1/2)^(t / 2.69)

Dividing both sides by 180g:

(22.5g / 180g) = (1/2)^(t / 2.69)

Taking the natural logarithm of both sides:

ln(22.5/180) = (t / 2.69) * ln(1/2)

Simplifying:

t = (2.69 / ln(1/2)) * ln(22.5/180)

t ≈ 6.27 years

Therefore, it would take approximately 6.27 years for a 180g sample of radioactive gold (with a half-life of 2.69 years) to decay to 1/8 its original mass.

Answer:

Explanation:

When a meal containing fried fish and toast bread is consumed, it goes through a series of processes in the digestive system of a human. Here's a general description of how the components are processed:

1. Mouth: The process of digestion begins in the mouth. Chewing breaks down the toast bread and fish into smaller pieces, while saliva mixes with the food to start the breakdown of carbohydrates.

2. Esophagus: The chewed food, now called a bolus, is swallowed and travels down the esophagus through peristaltic contractions. The esophagus carries the food to the stomach.

3. Stomach: The stomach is responsible for further mechanical and chemical digestion. It mixes the food with stomach acid and digestive enzymes to break down proteins. The fried fish is broken down into smaller pieces through mechanical churning.

4. Small Intestine: The partially digested food leaves the stomach and enters the small intestine. Here, bile from the liver and enzymes from the pancreas break down fats, while other enzymes continue the breakdown of proteins and carbohydrates. Nutrient absorption occurs through the walls of the small intestine and is facilitated by small finger-like projections called villi.

5. Large Intestine: Any remaining undigested food, as well as water and electrolytes, pass into the large intestine. The large intestine absorbs water and electrolytes while forming waste material known as feces.

6. Rectum and Anus: The feces are stored in the rectum until elimination through the anus occurs during a bowel movement.

Throughout this process, various digestive enzymes and gastric juices are secreted at different stages to facilitate the breakdown and absorption of nutrients. The fried fish and toast bread are broken down into smaller molecules, such as proteins, carbohydrates, and fats, which are then absorbed into the bloodstream to provide energy and nourishment for the body.

Answer:

The Cardiovascular System

Explanation:

The respiratory system draws air into the lungs.  Oxygen diffuses through the walls of the alveoli and across the walls of the capillaries where it enteres the bloodstream.  The oxygen molecules are picked up by red blood cells, which are pumped through the blood vessels by the action of the heart.  As the red blood cells carrying oxygen pass through capillaries near the cells, oxygen diffuses into the cells.

Answer:

The respiratory system collaborates with the circulatory system to deliver oxygen and remove metabolic waste. It also aids in blood pH regulation. Respiration is the process through which oxygen and carbon dioxide are exchanged between the atmosphere and the body's cells.

The clownfish's reproductive strategy of laying eggs near a sea anemone is a form of protection and survival for its offspring.
