A. The following statements are hypotheses:
1. Glucose may cause an increase in bacterial growth.
2. Increased glucose may lead to capsule formation in bacteria.

B. The following statements are observations:
1. The bacterial colony grown without glucose do not have capsules around their cells.
2. Bacteria growth in the glucose environment increase rapidly and then stopped after sometime.

Gastrulation, when the cells organize themselves into an embryo occurs 2 weeks after conception. What do the 3 layers of cells g
Travka [436]

Answer:

Gastrulation is the process where the developing embryo forms the process of the 3 germ layers. These germ layers are formed due to the movement of the single-layered blastula. Gastrulation starts during the third week of the human embryo.

The three germ layers give rise to different organs of the fetus. The 3 layers are ectoderm or outer layer, mesoderm or middle layer, and endoderm or inner layer.  

These 3 germ layers give rise to different organs of the human fetus. Ectoderm forms epidermis, skin, hair, olfactory organs, eye lense. glands like pituitary. Sensory nerves, skeleton, pigment cells are also formed from ectoderm.  

Ectoderm also forms a neural tube that further divides to form the brain, spinal cord.

Mesoderm form the vertebral column, skeletal muscle, excretory organs, reproductive organs. It also forms blood cells, blood vessels, body cavity or coelom.

The inner layer endoderm gives rise to the lining of the digestive tract, liver, pancreas, bladder, etc.

Feliz [49]

Transport of a substance from the lumen (cavity) of an organ into one side of a cell and out the other side of the cell into the extracellular fluid is called <u>transcellular transport</u>.

The two routes of transport of substances across the epithelium of the gut are by transcellular method and paracellular method.

Transcellular transport refers to the transport of solutes across a epithelial cell layer through the cells.  The best example is the movement of glucose from the intestinal lumen to the extracellular fluid by the epithelial cells. The epithelial cells use the active transport to generate the transcellular transport. Active transport refers to the transport of substances from a region of its lower concentration to a region of its higher concentration against the concentration gradient using cellular energy.

Erythrocytes do not carry out aerobic respiration; thus, they do not consume any of the oxygen they are transporting.
photoshop1234 [79]
False
Erythrocytes also known as Red Blood cells carry oit aerobic respiration; thus, they consume any of the oxygen they are transporting. They transport oxygen and takes away carbon dioxide from the cells. It contains a pigment called haemoglobin that helps in this process......
