Biology is the study of living organisms, divided into many specialized fields that cover their morphology, physiology, anatomy, behavior, origin, and distribution.


This is basically the definition of biology, so you may need to add a little more detail. This is a great way to get it started though!!!

Hope this helps!!

Manifestations of osteoarthritis include ( Select all that apply.) nodules on joints of the hands. crepitus with joint movement.
fiasKO [112]

Answer:

All options are correct, that is, they would all be correct for osteoarthritis.

This disease is characterized by being very painful at the joint level, it is degenerative, and mobility decreases over time.

Explanation:

Osteoarthritis is a pathology that is based on the fegenerative destruction of the joints, generating edema and loss of function, that is why it is pain.

The pain is very intense and very marked, that is why it is treated with immunosuppressive drugs and analgesics. (In addition to kinesiology and physiotherapy).

This disease decreases the functional unit and the joint space, generating possible ankylosis, pseudoarthrosis, elimination of lubricating fluid from joints and nodular structures. These nodular structures tend to be more common in the hands and are called by professionals as "drum fingers".

max2010maxim [7]
The term aerobic exercise describes any type of exercise typically performed at moderate levels of intensity for extended periods of time that increases the heart rate. In such exercise, oxygen is used to "burn" fats and glucose in order to produce energy in the form of ATP, the basic energy carrier for all cells. Initially, glycogen is broken down to produce glucose, but in its absence, fat metabolism is initiated instead. Aerobic exercise is an exercise performed at a moderately high level of intensity over a long period of time. For example, running a long distance at a moderate pace.

Transcription in bacteria differs from transcription in a eukaryotic cell because __________________________. (a) RNA polymerase
Serggg [28]

The correct answer is: (a) RNA polymerase (along with its sigma subunit) can initiate transcription on its own.

More differences between prokaryotic and eukaryotic transcription:

• In prokaryotes transcription occurs in the cytoplasm (unlike in eukaryotes in nucleus) and it is simultaneous with translation,

• In prokaryotes there is only one type of RNA polymerase (in eukaryotes there are three types of them).

• There is no sigma subunit in eukaryotes, the initiation of transcription begins thanks to initiation factors.

• Promoter region in prokaryotes contains pribnow box, while in eukaryotes it contains TATA and CAT box.
