Answer:
The given statement is false, as some of the fruits like a banana do not contain seeds as they get propagated through the offsets. The development of banana takes place without fertilization, that is, via the procedure of parthenocarpy. All the fruits are also not sweet in taste like lemon is a fruit, which is sour in taste. Thus, all the fruits are sweet is also incorrect.
The answer is A I believe
Everything we have today is because of the industrial revolution
Answer:
false, first
Explanation:
The first law of thermodynamics states that energy cannot be created or destroyed. Plants do not create energy, but rather they harness it from the sun. They convert the light energy in the photons of sunlight into chemical energy in the bonds of carbohydrates they make. We get energy from consuming plants when we acquire and break down these chemical bonds in carbohydrates of plants for our cellular processes.
Answer:
a mutation that blocks the GTPase activity of Ras
Explanation:
A G protein in inactive state is GDP bound but as soon as a guanine exchange factor (GEF) exchanges it with GTP it gets activated which means that in GTP bound state it is active. G - protein has endogenous GTPase activity. Upon interaction of GAP, the GTPase activity of this protein is exhibited. When GAP is present, hydrolysis of GTP into GDP occurs which leads to inactivation of G protein. A mutation which will block GTPase activity of Ras will therefore result in constitutive active signaling even in the absence of ligand binding to it's receptor. In such scenario, GTP will not be hydrolyzed into GDP so signaling will be up-regulated.
