For #25:

Most bivalves are filter feeders, using their gills to capture particulate food such as phytoplankton from the water. The protobranchs feed in a different way, scraping detritus from the seabed, and this may be the original mode of feeding used by all bivalves before the gills became adapted for filter feeding

Which respiratory-associated muscles would contract or relax during forced expiration, for example blowing up a balloon?
Nutka1998 [239]
The correct answer is B, internal intercostal muscles and abdominal muscles would contract.
Exhalation is the flow of the breath out of the body. During forced exhalation, internal intercostal muscles contracts which lower the rib cage and decrease thoracic volume, while the abdominal muscles push up on the diaphragm which causes the thoracic cavity to contract.

What is a body function that would contribute to BMR?
swat32

Answer:

Breaking down a burger in the stomach.

Explanation:

Basal metabolic rate (BMR) also known as resting metabolic rate (RMR) can be defined as the amount of calories that is required to keep the human body to function properly and perfectly at rest.

This ultimately implies that, basal metabolism is the minimal amount of calories or energy that is required by an individual for maintaining vital functions such as blood circulation, keeping the body warm and respiration while fasting or in a complete mental and physical rest.

Some of the factors that affects the basal metabolism rate (BMR) in humans are height, weight, age, starvation or fasting, thyroxine, fever, stress, malnutrition and growth.

Hence, breaking down a burger in the stomach is a body function that would contribute to BMR.
