Because plants give us oxygen and without photosynthesis, plants will die so we won't have oxygen. That is why life will impossible without photosynthesis.

How do you find phenotypes?
bezimeni [28]

Answer:

Write the amount similar dominant  and different  squares as one phenotypic group. Count the amount of similar recessive squares as another group. Write the result as a ratio of the two groups. A count of 3 from one group and 1 from the other would give a ratio of 3:1.

A mutation in a G-protein prevents the alpha-subunit from dissociating from the beta/gamma-subunit. What effect will this have o
Ymorist [56]

Answer:

the pathway will be under-expressed.

  • the alpha subunit helps to bind with either GDP or GTP. when the α subunit is bound with GDP, it will be bound to β and γ subunits and thus forms an inactive state for G-protein.
  • when the alpha subunit binds with the GTP, it becomes activated and dissociates β and γ subunits.

if G-protein Coupled Receptor is unable from dissociating β and γ subunits, then the pathway will go under expression.  

The chemical qualities of the alpha subunit allow it to bind easily to one of two guanine subunits, GDP or GTP. The protein thus has two functional formations. When GDP is bound to the alpha subunit, the alpha subunit remains bound to the beta-gamma subunit to form an inactive trimeric protein.

G-proteins, cAMP, and Ion Channel Opening. The alpha subunit activates adenylate cyclase, in purple, and loses GTP. Adenylate cyclase converts ATP to cyclic AMP, which then activates Protein Kinase, shown in blue. Protein Kinase phosphorylates an ion channel, letting sodium ions rush into the cell.

As a result of the ligand binding to its site on the G-protein-linked receptor, A) the G-protein changes conformation and GTP replaces the GDP on the alpha subunit. ... Inactivation of the alpha subunit occurs when its own phosphorylase activity removes a phosphate from the GTP.

Sergeu [11.5K]
The two bacteria are considered to be anaerobic endospore-formers that deliver neurotoxins. Disease comes about when the endospores are brought profound into the tissues. The two neurotoxins meddle with engine control. Botulism poison, delivered by C. botulinum, ties the cytoplasmic films of engine neurons at the neurotransmitter and keeps the arrival of acetylcholine neurotransmitter and, subsequently, forestalls motioning to muscle cells. At the point when muscle cells don't get signals from engine neurons, they stay loose, bringing about a flabby loss of motion. The absence of engine control delivers a not insignificant rundown of side effects, the most genuine of which is a respiratory disappointment, on the grounds that respiratory muscles can be influenced by botulism poison.

bulgar [2K]

Answer:

i think is a but im not sure but i hope it helps.

Explanation:

During a baseball game, a player’s ball hit into the outfield is modeled by the equation h = –16t2 + 65t. A bird flying across the field follows the path modeled by the equation h = 8t + 20. Let t be the time since the ball is hit and h be the height.
