STatiana [176]

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.

Hypoxia is known to cause a disruption of somitogenesis. If a mouse embryo were temporarily exposed to low levels of oxygen duri
Pani-rosa [81]

The answer to this question is: abnormal development of the caudal (tail) vertebrae

Somitogenesis refers to the process during embryo development in which somites form. These somites are cells that will give rise to structures associated with the vertebrae body plan. Somites form sequentially from the head to the tail, where each new somite forms on the caudal or tail region of the previous one.  

Somitogenesis represents the first sign of segmentation of the developing vertebrate embryo. During somitogenesis, the unsegmented paraxial or presomitic mesoderm in the trilaminar embryonic stage is segmented in order to form pairs of somites. Moreover, caudal vertebrae refer to the bones that form the tail of vertebrates, which derive from caudal somites.

Embryo hypoxia refers to the condition in which the developing embryo does not receive sufficient oxygen (O2) supply. It has been shown that hypoxia during embryo development can increase the incidence of malformations. In this case, embryo hypoxia affects normal caudal somite segmentation, thereby leading to defects in the caudal (tail) vertebrae.

Neurons have special proteins in the cell membranes that control the flow of charged ions. Are these proteins most likely produc
Zielflug [23.3K]

The ribosomes on the rough endoplasmic reticulum (RER) most likely produces neuronal special proteins.

Explanation:

Conduction of electrical impulses by action potentials of neurons takes place through controlled flow of charged ions through neuronal membranes. This ion transfer is controlled by specialized neuronal channel proteins which are present in the neuronal cell membrane.  

These channel proteins allow for hydrophillic passage of ions and water molecules across the neuronal membranes.  

Ribosomes that are attached to the RER are involved in protein synthesis. They carry the code for proteins carried by the mRNA and translate into respective protein.

The RER along with some free ribosomes cluster together as Nissl bodies and are mainly involved in neuronal specialized proteins.
