Answer: B (GTP serves as the energy input for AMP synthesis from IMP)
Explanation:
In the de novo synthesis of purine nucleotide, IMP represents a branch point for purine biosynthesis. IMP can be converted to either AMP or GMP.
The formation of AMP from IMP requires GTP; similarly formation of GMP requires ATP. The conversion of IMP to either AMP or GMP is highly regulated – AMP and GMP inhibits their own formation by feedback inhibition of adenlyosuccinate synthetase and IMP dehydrogenase.
Answer:
pic 1 red giant, a star whose outer shell has expanded and cooled
pic 2: supernova, a shock wave produced by extremely high temperatures
pic 3: black hole, a high mass star that has collapsed from gravity
pic 4: white dwarf, a low mass star that has shed its outer layers
Explanation:
Responder: Un pronóstico de siete días puede predecir con precisión el clima alrededor del 80 por ciento del tiempo y un pronóstico de cinco días puede predecir con precisión el clima aproximadamente el 90 por ciento del tiempo. Dado que no podemos recopilar datos del futuro, los modelos tienen que usar estimaciones y suposiciones para predecir el clima futuro.
Muscle tissue is comprised of groups of muscle cells, laid out in differing organizations depending on the muscle tissue type. For skeletal muscle tissue, the muscle tissue works together to push or pull the skeleton and move the organism conciously. For smooth muscle, the muscle tissue works together to push, pull, or constrict various structures unconciously. An example of smooth muscle is the muscles involved in pushing food through the esophagus. For cardiac muscle, the muscle tissue works together to pump the entire heart in tandem.
Answer:
I have matched them below
Explanation:
each of the columns have been properly matched below:
1. attaches bones to bones and muscles to bones = d. dense regular connective tissue
2. insulates against heat loss = a. adipose connective tissue
3. forms the fibrous joint capsule =
c. dense irregular connective tissue
4. makes up the intervertebral discs = g. fibrocartilage
5. composes basement membranes; a soft packaging tissue with a jellylike matrix = b. areolar connective tissue
6. forms the larynx, the costal cartilages of the ribs, and the embryonic skeleton = h. hyaline cartilage
7. provides a flexible framework for the external ear = e. elastic cartilage
8. provides levers for muscles to act on = i. osseous tissue
9. forms the walls of large arteries = elastic connective tissue
