1 answer:
monitta3 years ago
8 0

Answer:

Similarly, enzymes can only function in a certain pH range (acidic/alkaline). Their preference depends on where they are found in the body. For instance, enzymes in the intestines work best at 7.5 pH, whereas enzymes in the stomach work best at pH 2 because the stomach is much more acidic.

Which body composition measuring system uses the volume of a controlled chamber compared to body volume to determine bodyfat per
krok68 [10]

Air displacement plethysmography (ADP) measures the volume of a controlled chamber compared to body volume to determine body fat percentage.

<h3>What is Air displacement plethysmography (ADP)?</h3>

A two-component model called air displacement plethysmography (ADP) measures mass and volume, allowing for an assessment of body density (Db). This allows for the estimate of fat and fat-free mass using body density, which is calculated by dividing mass by volume (FFM).

With air-displacement plethysmography, an object's volume is indirectly determined by calculating how much air it displaces inside a sealed chamber (plethysmograph). Therefore, a patient is placed inside the chamber and their body volume is measured by how much air they can move while sitting within.

romanna [79]

Answer:

Gastrula

Explanation:

A hollow shaped embryonic structure formed after two weeks of fertilization with three layers is known as gastrula.

The gastrula is formed from the repeated division of the single-layered structured called blastula which later forms three layers called ectoderm, endoderm and mesoderm.

These layers during the process of gastrulation from different organs of the multicellular organisms like the endoderm forms the liver, the ectoderm form the nervous system, the skeletal bone and many others.

Since gastrula structure contains three dermal layers therefore gastrula is the correct answer.

Answer:

true

Explanation:

stars can change bc Stars change over time. ... It is in the clouds of dust and gas that stars are born. As more and more of the gas (which is mostly hydrogen) is pulled together by gravity into a cloud, the cloud starts to spin. The gas atoms start to bump into each other faster and faster.

What encourages flooding by allowing water to run off into streams?
expeople1 [14]

Deforestation encourages flooding by allowing water to run off into streams

<u>Explanation</u>:

Deforestation plays vital roles in the flooding. The roots of the Trees prevent sediment runoffs and forests hold more water than farms or grasslands.Firstly the leaves in the trees will capture some amounts of water which will be eventually evaporated. Secondly, some quantity of water is  absorbed by the tree's roots. Also,Tree roots hold the soil in place, reducing the movement of sediment that can shrink river channels downstream..

The process of deforestation will lead to dislodging of the topsoil. this makes the  topsoil unstable and reduces its capacity to hold down the water
