Answer:The correct answer is letter A.
Explanation: he is right
Your teacher gives you an unknown protist to classify that is currently inactive. The protist appears to have long lash-like
appendages protruding from its cell surface. Which kind of locomotion can we expect from this protist? (1 point)
The appendages of this protist will move in a dragging motion that actively pulls the protist forward.
O The appendages of this protist will move in a sweeping motion like oars to actively propel the protist forward.
The appendages of this protist will move back and forth like a wagging tail to actively propel the protist
forward
O The appendages of this protist are not functional, and the protist moves passively via environmental forces.
Answer:
your answer is 6
Explanation:
C6H12O6 + 6O2 → 6CO2 + ?H2O + Energy
H12O6---> 2 hydrogen and 1 oxygen for very water molecule. 12 ÷ 2= 6 which means 6H2O
Answer:
Microscopes are often used to examine specimens which are too small to see in detail using only the human eye. Which of the following procedures should be followed prior to placing a specimen slide on the stage of the microscope?
Turn the objective lens to the lowest magnification setting.
Explanation:
Turnin of objective lens to the lowest magnification enhances visibility which would allow the lens to focus on the specimen clearly. It is always important to start with the lowest magnification.
The right answer is blastocyst.
The blastocystic Stage of embryo development is characterized by the formation in the center of the morula (embryonic cell group) of a cavity isolated from the external environment: the blastocoele.
In embryonic development, this step precedes gastrulation.
Blastocysts are indeed composed of a hundred cells; they have the shape of a hollow sphere at the bottom of which is the mound of the "embryonic bud" from which the embryonic stem cells are derived.
Answer:
Option D
Explanation:
Whether a G alpha subunit is active or inactive depends on which guanine nucleotide is bound to it. Binding of GDP or GTP results in the protein switching between two conformational states.
Dissociation of GDP for GTP with the G alpha subunit structurally shifts the switch II helix region, allowing for the association of G alpha with its effector proteins, such as adenylate cyclase,describes the structural changes that occur in a G alpha subunit due to guanine nucleotide binding
