Answer:

Blood vessels and nerve fibers

Explanation:

The Haversian canal serves as the bone tissues and it runs through the core of each osteon. The osteon surrounds the Haversian canal and contain structures called lamellae.

These lamella are made largely of collagen fibers and also various network of rich blood vessels and cells which produces blood cells in the body. Nerve cells which helps in the relay of impulses are also present. The rich contents of the bone gives it its strength and durability.

Answer:

The correct answer is: blood vessels and nerve fibers.

Explanation:

Haversian Canals are a group of tubes that are located in the more peripheral region of the bone, known as the cortical bone. The cortical bone is hard and compact and is composed of several concentric layers of bone cells (osteocytes and osteoblasts) that circle around a haversian canal, which contains capillaries and nerve fibers. This structure is called an osteon.

Haversian Canals are very important for the correct functioning of the bone, as they give the cells their needed blood supply and innervation.

Answer:

Living things use structural strategies and behavioral strategies that increase their chances of reproduction.

Living things do so to reach the reproduction goal that is to pass genes on to offspring. For example: the pouch of a kangaroo, a frog croaking a mating call,  and colorful petals of flower etcetera helps in increasing mating chances so that their genes can be followed to the generation.

The pairing of complementary strands of DNA due to hydrogen bonding is called semi-conservative replication.

The biological process of creating two identical copies of DNA from a single original DNA molecule is known as DNA replication.  All living things replicate their DNA, which is the primary mechanism for biological inheritance. This is necessary for:

A double helix (two linear strands that run counterclockwise and twist together) of two complementary strands makes up DNA.

These strands are split apart in the replication process. The mechanism of semiconservative replication uses each strand of the original DNA molecule as a template to create its counterpart. The new helix will be made up of an original DNA strand as well as a freshly synthesized strand as a result of semi-conservative replication.

Answer:

- Pesticide 1: Induces transition mutations. Rat liver enzymes convert it into a nonmutagenic product. Does not induce frameshift mutations.

- Pesticide 2: Does not induce transition mutations. Rat liver enzymes convert it into frameshift mutagen.  

- Pesticide 3: Induces transition mutations. Rat liver enzymes don't have ability to convert compounds into mutagens. Does not induce frameshift mutations.

Explanation:

The Ames test is a technique widely used to evaluate the mutagenic potential of a particular chemical compound. The Ames test uses Salmonella typhimurium strains with a defective mutation that makes them unable to synthesize histidine. When the mutation is reversed, then the revertant strains can grow on a medium lacking histidine. A positive test shows that the chemical is mutagenic because its activity is associated with the reversed mutation and thereby the mutant gene regains its function. In humans, as well as in other mammals, many chemicals don't have mutagenic effects themselves but they may become converted into mutagens when are metabolized by the body. For that reason, rat liver enzymes are added to replicate the metabolic effects of the chemical compound being tested. Nowadays, current tests can express recombinant human proteins instead of rat liver enzymes, thereby enabling a better correlation between mutagenic activity and human metabolic processes.

Answer:

The crane has a sharp and pointed beak adapted for catching and grasping prey. The sharp beak allows the crane to effectively stab and pierce its prey, such as fish, frogs, or small animals. The pointed shape helps the crane to accurately target its prey and secure a firm grip.

On the other hand, the duck has a flat beak, which is better suited for its specific feeding habits. Ducks are primarily filter feeders, and their flat beak enables them to sift through water or mud to collect small organisms, insects, and plants. The flat beak acts like a sieve, allowing the duck to strain out food particles while retaining water.

The difference in beak shape between the crane and the duck reflects their distinct feeding strategies and ecological roles. Each species has evolved its beak shape to optimize its ability to capture and consume the specific types of food sources available in their respective habitats.

When talking about specific heat, it is correct to say that a gas's specific heat may be determined at constant pressure. The correct option is B.

The amount of heat needed to increase a substance's temperature by 1 degree Celsius or Kelvin is known as its specific heat. The specific heat of a gas can be measured at constant pressure.

The specific heat for gases can be calculated at either constant volume or constant pressure. The heat capacity at constant pressure (Cp) and heat capacity at constant volume (Cv) are the terms used to describe the specific heat when measured at constant pressure and constant volume, respectively. For the majority of gases, Cp has a larger value than Cv.

Thus, the ideal selection is option B.

In the story "Purple Hibiscus" by Chimamanda Ngozi Adichie, Aunty Ifeoma might lose her job as a professor at the University because her name is on a list of those who have been allegedly disloyal to the University.

Aunty Ifeoma replies to the bearer of the news saying she is not paid to be loyal. She says that when she speaks the truth, it becomes disloyal. Amaka and Obiora argue again on the same subject because eventually the authorities force their way into their home, create a scene by messing up their belonging, and leave with a warning to Aunt Ifeoma to be careful.

Purple Hibiscus by Chimamanda Ngozi Adichie examines themes of religious hypocrisy, finding one's voice, and the perseverance of love via the tale of Kambili Achike, a young Nigerian lady attempting to make her place in a society plagued with war and turmoil.

The main topic of Purple Hibiscus is the search for freedom in the face of oppression. However, the story allows the reader to understand other subjects that emerge due to it, such as violence, corruption, and even religion. The novel's backdrop appropriately displays the concept of freedom.

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.
