9. Look closely at the illustration above. a. What process is occurring? b. What is being made? c. How can you tell?
Answers
A. DNA replication in the nucleus of a cell
B. From one helix of DNA in a replication process, we get two: The DNA is a double helix and it consists of two strands of specifically connected amino-acids. When the time for replication comes, a set of enzymes unwind the two strands and leave them as a base for additional two strands attaching to them - the green line is an example of that. The free nucleotides - adenine, guanine, thymine and cytosine are left open and the enzyme called DNA-polymerase helps to produce a new strand on the template of the old parental one (one of the blue ones in the picture)
C. By the location on the smaller picture - replication takes place in the nucleus. And the most important hint are the letters A - adenine, G - guanine, T- thymine, and C-cytosine. A connects with T, and G connects with C.

Answer : The correct answer is- Force acting upon the object and the mass of the object.
Acceleration can be described as rate of change of velocity of a particular object with respect to time. In other words, an object is said to be in acceleration when its velocity changes with respect to time.
According to Newton's second law of motion,
F = m X a
a = F/m
Where, F = force acting on an object, m is the mass of an object, and 'a' is the acceleration.
Thus, force and mass are the two forces that affect the level of an object's acceleration.

Answer:
Enzyme activity decrease at these temperatures.
Explanation:
Photosynthesis is facilitated by the action of various enzymes and involves light and dark reactions. In light reactions chlorophyll absorbs sunlight and creates ATP AND NADPH. In dark reactions carbon is fixed using the ATP and NADPH.
The efficiency of all these activities depends on the activity of enzymes which depends on the temperature. The optimum temperature range where the enzyme activity is optimal is about 10°c - 20°c. At low temperatures and high temperatures enzyme activity is less efficient.
At a temperature above 38°c and below 0°c enzyme activity decreases.

Answer:
Halita is no more valuable than gold.
Explanation:
Halite is a sedimentary rock salt of formula NaCl. In short, halite is a salt and is neither more precious nor more valuable than gold.
As a matter of curiosity, we can say that halite is a slightly rosy white crystal, transparent, glassy, hardness 2, density 2.1 - 2.2. One of its particular properties is its salty taste. The presence of impurities can give it a reddish, brownish or even bluish or greenish tinge in case of radioactivity.
