Explanation:
A mutation in E. coli is found that fails to induce the lac operon even when IPTG is added (IPTG is an inducer of the lac operon that enters the cell by passive diffusion). Which of the following could explain this phenotype (you may choose one or more answers)?
a. Mutation in the promoter of the lac operon.
b. Mutation in the operator of the lac operon.
c. Mutation in the repressor for the lac operon.
d. Mutation in the Z gene for beta galactosidase.
e. Mutation in the Y gene for Lac permease.
f. Mutation in the gene for adenylate cyclase.
g. Mutation in the gene for CAP (or CRP) protein h) Mutation in the gene for rho factor
i. None of the above
1. What is a wave and where do all ocean waves come from?
Answer:
Wave is a water disruption that causes ripples that can be big or small
Waves occur because of the gravitational pull from the moon.
Answer:
In science, a wave is defined as a transfer of energy. Ocean waves are caused by wind moving across the surface of the water. The friction between the air molecules and the water molecules causes energy to be transferred from the wind to the water. Waves are mostly caused and come from wind.
Modern whales evolved from mammals that lived on land. Fossil evidence reveals that one characteristic that has changed over time is the position of whales nostris. The images below show the skills of a modern whale

cientists think that the position of the nostrils gives modern whales an evolutionary advantage. Which of the following most likely describes how this adaptation is advantageous?
O The nostril position allows whales to obtain air more easily at the surface of the water.
The nostril position allows whales to obtain food more easily at the surface of the water.
O The space lett empty by the migrating nostrils has allowed modern whales to develop gills.
The space left empty by the migrating nostrils has allowed modern whales to develop teeth.
Answer: Its A my friend, how it helps!.
Explanation: I just completed the Test.
The nostril position allows whales to obtain air more easily at the surface of the water is most likely describes the advantage of adaptation.
What do you mean by adaptation?In biology, adaptation has three related meanings. It is the dynamic evolutionary process of natural selection that fits organisms to their environment, enhancing their evolutionary fitness. Secondly, it is a state reached by the population during that process.
The ability of living organisms to adjust themselves to their surroundings is called adaptation. Adaptations are the changes in structure or behaviour of an organism that will allow the organism to survive in that habitat.
Adaptations are unique characteristics that allow animals to survive in their environment. There are three types of adaptations: structural, physiological, and behavioral.

explain the flow of energy of candles
Answer:
The wax vapor catches light and burns, sending a flame high above the wick. Heat from the flame travels in three directions at once by processes called conduction, convection, and radiation. Convection draws hot wax vapors out from the wick and sucks oxygen from the surrounding air into the base of the flame.
Explanation:
Answer:
The heat from the wick melts the wax which gets absorbed in the wick and then gets burnt (which is really oxidation) to produce heat energy as well as light energy. The energy transforms from chemical energy to heat and light energy. Because when the candle burns a chemical reaction occurs, and produces heat and light.

How many daughter cells does mitosis produce?
A) 2.
B) 4
C) 23
D) 46
Answer:
A) 2.
I hope it helps :)
Explanation:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Mitosis itself consists of five active steps, or phases: prophase, prometaphase, metaphase, anaphase, and telophase.
