In unicellular organisms, one cell must carry out all the functions of life.

Svet_ta [14]

Answer: The answer is true!

Explanation: The one cell of a unicellular organism must be able to perform all the functions necessary for life. These functions include metabolism, homeostasis and reproduction. Specifically, these single cells must transport materials, obtain and use energy, dispose of wastes, and continuously respond to their environment.

Which is most compromised in the seated dental professional?

Black_prince [1.1K]

The most compromised part of the body in the seated dental professional is the lumbar curve. The dental professional most of the time works seated or rotated at the hips. The human adult spine has normally three curves: the cervical (neck), the thoracic (middle back) and the lumbar (lower back). The lumbar curve plays a very important part in keeping the body's balance in an upright position. When working seated, the whole body tilts forward or twists, two situations that apply great pressure on the lower back.

Observation: characteristics of cockroach. There are<br>pairs of walking legs.

Lina20 [59]

Answer:

<h2>Cockroaches are generalized insects with few special adaptations, and may be among the most primitive living Neopteran insects. They have a relatively small head and a broad, flattened body, and most species are reddish-brown to dark brown. They have large compound eyes, two ocelli, and long, flexible antennae.</h2>

three pairs

Thorax. On the thorax, all cockroaches have three pairs of legs. Adults of most of the domestic species have two pairs of wings, although one species, the oriental cockroach, has poorly- developed wings in both sexes.

List and briefly describe the chemical sequence of events in the fight-or-flight response to a threatening situation from the bi

777dan777 [17]

Answer:

Binding taking place at the receptor site

G protein activates in the cell membrane

Conversion of GDP → GTP

Activation of adenylate cycles

Cyclic production of AMP → ADP

Initiation of the desired reaction in regard to the original message

Cyclic restoration of AMP → ATP

Explanation:

The description of the mechanism:

Right off the bat, epinephrine attaches to a molecule called a receptor (beta-adrenergic protein).

G protein, which is found on the inner side of the plasma membrane, is activated when epinephrine binds to it.

The GDP-carrying Alpha subunit of G protein is isolated during activation. After that, the GDP is translated to GTP.

Adenylate cyclase is then activated by GTP.

The only enzyme that can catalyze the transformation of ATP to CAMP is adenylate cyclase (Cyclic adenosine monophosphate). As a result, the CAMP molecule (secondary messenger) is produced.

CAMP stimulates protein kinase A, and the cycle repeats till the glycogen phosphorylase enzyme is triggered.

After that, the cyclic amp is brought back and restored.
