salivary glands exhibit compound tubule-alveolar glandular arrangement. a. true b. false
Answers
The statement "salivary glands exhibit compound tubule-alveolar glandular arrangement" is true.
Salivary glands are exocrine glands that secrete saliva into the oral cavity to aid in digestion and lubrication. These glands are classified as compound tubulo-alveolar glands because they are made up of both tubular and alveolar structures.
The tubular structures are long, thin tubes that carry the saliva from the secretory cells to the ducts that lead to the oral cavity. The alveolar structures are small sac-like structures that contain the secretory cells responsible for producing the saliva.
The combination of these structures creates a compound tubule-alveolar glandular arrangement that allows for efficient secretion and delivery of saliva. This arrangement also allows for the different types of salivary glands to have their own unique composition of tubules and alveoli, which determines the type of saliva they secrete.
Overall, the compound tubule-alveolar glandular arrangement is an important feature of salivary glands that allows for the efficient production and delivery of saliva, which is essential for oral health and digestion.

Which feature is an example of physiological adaptation?
Answers
Answer:Octopuses ability to squirt ink.
Physiological adaptations are those adaptations which occurs at the metabolic level in the organisms. These adaptations occurs in the cells, tissues and organs of the body of the organism in response to external environmental stimulus. Physiological adaptations are beneficial for the survival of the organisms against predators. These adaptations generates a defense mechanism in the body of the organism, in order to increase it's chances of survival.
Octopuses ability to squirt ink is an example of physiological adaptations as the ink is released in the water by these organisms in order to escape themselves from predators.

What are the effects of climate change and natural catastrophes on our ecosystem and people?Climate change is indeed having an effect on health in a variety of ways, including the increased frequency of severe weather events such as heatwaves, cyclones, and floods, the disruption of food systems, rises in zoonoses and food-, water-, and vector-borne illnesses, and mental health problems.
Why is climate change a potential disaster?Climate change will thus affect disaster risks in two ways: first, by increasing the likelihood of weather and climate hazards, as well as the effects of sea-level rise; and second, by increasing the vulnerability of communities to natural hazards as a result of ecosystem degradation, water and food shortages.

Antibodies are globular proteins that fold on themselves because of hydrogen bonding.

Answers
The correct example of quaternary protein structure is four globular subunits joining together to form functional hemoglobin, option (d) is correct.
Hemoglobin, a protein present in red blood cells, plays a crucial role in transporting oxygen throughout the body. Its structure comprises four subunits, each housing a heme group that facilitates oxygen binding. These subunits come together through various interactions, including hydrophobic interactions, hydrogen bonding, and sometimes disulfide bonds, to form a functional hemoglobin molecule.
This quaternary structure is crucial for hemoglobin's ability to efficiently transport oxygen. Each subunit contributes to the overall structure and function of the hemoglobin molecule, and any disruption in the quaternary structure can lead to functional abnormalities, such as sickle cell anemia, option (d) is correct.

you think their per capita consumption would be every week?
A. 0 gallons per person
B. 2 gallons per person
C. 1 gallon per person
D. 3 gallons per person
Answers
The answer to this question is C, which is 1 gallon per person.
Per capita consumption refers to the average consumption of a particular resource or product per person. In this case, if each person in a house drank 1 gallon of bottled water each week, then the per capita consumption would be 1 gallon per person every week. It's important to note that this assumes that the same amount of water is consumed by every person in the house, and does not account for any additional water usage such as cooking, cleaning, or bathing. It's also important to consider the environmental impact of using bottled water, as the production and disposal of plastic bottles contributes to pollution and waste. Ultimately, it's recommended to reduce bottled water consumption and switch to reusable water bottles or filtered tap water.

Identify a point source and a non-point source pollutant in your environment. Write a short report discussing these pollutants.
Answer: Point source pollutant: My school is situated near a river. A wastewater treatment plant is a few miles away. The plant uses certain chemicals to treat wastewater, but releases effluents into the river. Although the plant regulates the released effluents, the treatment system gets overloaded during heavy rainfall. As a result, untreated chemicals and wastes enter the river. The plant thus becomes a point source pollutant for the river. The wastes and chemicals entering the river adversely affect growth of plants and fishes in the water body.
Non -point source pollutant: I live in a residential area that has a groundwater reservoir. Last month, the authorities in my area complained that the water in the reservoir was getting polluted. On investigating, they found that rainwater picks up debris and pollutants from roads and sidewalks as it flows on its path. The polluted water enters waterways that are connected to the groundwater reservoir. The debris and pollutants are many in number, and it was difficult to trace exactly where the rainwater picked them up. However, these pollutants affect large areas because the water from the groundwater reservoir reaches many homes. Therefore, the debris and pollutants are non-point source pollutants.
