Exercise cannot be sustained when anaerobic respiration takes place in muscle cells.
Explain why.​

Upon fertilization, the zygote would have a different number of chromosomes from the parents. Gametes would be diploid instead of haploid.

In meiosis I (first row), meiosis II (second row), and mitosis, nondisjunction, in which chromosomes fail to split equally, can take place (third row). These uneven separations can result in aneuploids, or daughter cells with unusual chromosomal counts.

Gametes need to have half the number of chromosomes found in healthy body cells because the zygote has to have genetic material from both the mother and the father. The number of chromosomes must therefore be divided in half during meiosis.

Mutable tissue is a unique characteristic found in echinoderms, which allows them to change the mechanical properties of their connective tissues.

In sea stars, also known as starfish, mutable tissue primarily helps in locomotion and prey capture. Sea stars have tube feet, which are small, suction-cup-like appendages that they use to move and grasp objects. The mutable tissue within their tube feet and body walls can quickly switch between stiff and soft states, allowing them to hold onto surfaces or objects tightly while still having the flexibility to move around. This adaptability enables sea stars to navigate varied terrains and capture prey effectively.

On the other hand, sea cucumbers use their mutable tissue for different purposes. They rely on the tissue's capacity to change between rigid and flexible states for both defense and feeding. In the event of a threat, sea cucumbers can rapidly stiffen their body walls, making it difficult for predators to grasp or bite them. Conversely, they can also soften their body walls to enable easy ingestion of sediment, which they filter for organic material to consume. This mutable tissue property is vital for sea cucumbers' survival and adaptability in their environment.

In summary, mutable tissue is an essential feature among echinoderm groups like sea stars and sea cucumbers. While both species utilize this characteristic to adapt to their surroundings, they employ it differently, with sea stars using it for locomotion and prey capture, and sea cucumbers using it for defense and feeding.

The most common cause of a stroke is a clot blocking a brain artery. Heparin would prevent new clots from forming. It is contraindicated in cases of subarachnoid hemorrhage because it is ineffective in treating bleeding from damaged arteries.

The majority of the contraindications to intravenous (IV) recombinant tissue plasminogen activator (rtPA) injection began as exclusion criteria in large stroke trials.

Expert consensus was used to develop these for the National Institute of Neurological Disorders and Stroke (NINDS) experiment. Despite the fact that the safety and efficacy of IV rtPA have been consistently established in major worldwide observational studies over the last 20 years, most patients with acute ischemic stroke remain untreated.

Diuretics are a type of medication that increases the volume of urine produced by the kidneys. Diuretics are usually used to treat hypertension and edema. These medications affect the function of the kidneys and help remove excess fluids from the body. Diuretics primarily work on the proximal and distal convoluted tubules of the nephron.

Diuretics are a group of medicines that function to remove salt and water from the body through the urine. The use of diuretics results in an increase in the production of urine. The diuretic medication is usually prescribed for people with hypertension, heart failure, and edema.

Diuretics primarily work on the proximal and distal convoluted tubules of the nephron. The proximal convoluted tubule is where most of the reabsorption of water and solutes occurs. The distal convoluted tubule regulates the concentration of electrolytes in the urine. The use of diuretics includes the treatment of hypertension, congestive heart failure, liver cirrhosis, and kidney disease.

Diuretics are also used in sports as a doping agent to help athletes lose weight quickly. However, the use of diuretics as a doping agent is banned by the World Anti-Doping Agency (WADA).In conclusion, diuretics are medications that increase urine production by affecting the function of the kidneys. Diuretics primarily work on the proximal and distal convoluted tubules of the nephron.

The use of diuretics includes the treatment of hypertension, edema, heart failure, and kidney disease.

The deep facial bones that separate the oral and nasal cavities and form the nasal septum are known as the ethmoid bone, the vomer bone, and the maxilla bone.

These bones are responsible for maintaining the structural integrity of the face and supporting the various functions of the oral and nasal cavities. The ethmoid bone, in particular, plays a crucial role in separating the two nasal cavities and providing structural support for the nasal passages. The vomer bone, on the other hand, helps to form the lower part of the nasal septum, while the maxilla bone contributes to the overall structure of the upper jaw and helps to support the teeth and gums. Together, these deep facial bones play an essential role in maintaining the health and proper functioning of the oral and nasal cavities.

The deep facial bone that separates the oral and nasal cavities and forms the nasal septum is the "vomer" bone. The vomer is a thin, flat bone that is located in the midline of the skull and divides the nasal cavity into left and right halves. It plays an essential role in supporting the structure of the nasal cavity and contributing to the overall structure of the face.

Explanation:

Sorry, I know its late. I just took the test and was looking for the answer.

One example of a niche is a lion hunting for zebra in a grassland. The correct option is C.

The term “niche” in ecology refers to the function an organism performs within a community. The physical and environmental requirements (such as temperature or terrain) and interactions with other species that a species must tolerate make up its niche (like predation or competition).

A niche is a particular segment of the market that is connected by an affinity group or demographic. For instance, if you work in the children's clothing industry, you might specialize in outerwear or athletic wear.

The ecological niche explains how a population reacts to resource availability and competition, as well as how much total environmental space an organism takes up.

Cardiac muscle is an effector in the system that maintains blood pressure.

A body part known as an effector is one that receives signals from a control center and responds to them in order to keep homeostasis. The regulatory systems that monitor and control blood pressure levels would be the control center in the context of sustaining blood pressure.

In this instance, the effector is the heart muscle, which contracts or relaxes in response to signals from the control center to modify the force and rate of blood flow, which in turn affects blood pressure.

The inheritance pattern in the pedigree is autosomal dominant. This can be concluded because affected individuals appear in every generation and can have unaffected parents. Additionally, the trait affects both males and females equally. Finally, if an affected individual mates with an unaffected individual, approximately half of their offspring will be affected, which is consistent with an autosomal dominant pattern of inheritance.

Obstructive Disorders:
- Decreased airflow by bronchoconstriction
- Heavy smokers
- Asthma
- Bronchitis

Restrictive Disorders:
- Tuberculosis
- Neuromuscular disorders
- Weakening of respiratory muscles
- Fibrosis caused by coal dust

Obstructive lung disorders are characterized by a decreased airflow due to partial or complete obstruction of the airways. The obstructive disorders listed in the question are asthma, bronchitis, decreased airflow by bronchoconstriction (as seen in conditions like chronic obstructive pulmonary disease, or COPD), and heavy smokers. In these conditions, the airways become narrow and obstructed, making it difficult for air to flow in and out of the lungs, leading to symptoms like wheezing, coughing, and shortness of breath.

On the other hand, restrictive lung disorders are characterized by a decrease in lung volume due to stiffness or restriction of the lung tissue itself, the chest wall, or the respiratory muscles. The restrictive disorders listed in the question are neuromuscular disorders (such as muscular dystrophy or amyotrophic lateral sclerosis), fibrosis caused by coal dust (as seen in pneumoconiosis), and weakening of respiratory muscles (as seen in conditions like myasthenia gravis). In these conditions, the lungs are unable to expand fully, leading to reduced lung volumes and difficulty breathing.
