Answer;

Complementary base pairs;

- Adenine-Thyamine and Guanine-Cytosine (A-T and G-C)

Explanation;

-According to Chargaf's rule, the secondary structure of the DNA requires that every guanine pairs with a cytosine and every thymine pairs with an adenine, resulting in consistent ratios between the nucleotides.

-In double-stranded DNA, two long molecules twist around one another in a double helix.  Pairs of nitrogenous bases are set in the same plane, and interact with each other via hydrogen bonding. These pairs are often referred to as base pairs

Since the 1970’s, the Earth has been warming. Can this be due to natural, increased solar output? Why or why not?
Margarita [4]
No.

The Sun can influence the Earth’s climate, but it isn’t responsible for the warming trend we’ve seen over the past few decades. We know subtle changes in the Earth’s orbit around the Sun are responsible for the comings and goings of the ice ages. But the warming we’ve seen over the last few decades is too rapid to be linked to changes in Earth’s orbit, and too large to be caused by solar activity.

Explain, in your own words, how you would use the light microscope to view a wet mount of a protist, assuming the microscope is
aev [14]

Answer:

Please find the detailed explanation/description on how to use the light microscope to view a wet mount of a protist. The 9 structures mentioned in the question are in CAPS.

Explanation:

- Firstly, the slide containing the wet mount of the protist is prepared and placed at the centre of a lowered STAGE. The STAGE CLIPS over the sides of the slide are used to hold it in place.

- The revolving turret or nosepiece is turned so that the LOWEST POWER OBJECTIVE LENS is in position i.e. directly above the sample/slide. The SCANNING OBJECTIVE LENS, the lowest objective lens with power of 4x is used initially.

- The slide is viewed through the EYEPIECE, and the image is brought into focus using the STAGE KNOBS.

- The COARSE FOCUS KNOB is turned until the protist on the slide is brought into broad focus. The FINE FOCUS KNOB is then used to bring the image on the slide into sharp focus.

N.B: The OBJECTIVE LENS should not touch the cover slip on the slide during this process.

- When the protist on the slide is clear using lowest power objective lens, the revolver turret can be rotated to allow HIGHER POWER OBJECTIVE LENS.

- Due to higher magnification of the HIGH POWER OBJECTIVE LENS, the protist might need to be refocused using the FOCUS KNOBS.

Paraphin [41]

Answer:

Preschoolers, ages three to six, should be at the "preoperational" stage of Piaget's cognitive development theory, meaning they are using their imagery and memory skills. They should be conditioned to learning and memorizing, and their view of the world is normally very self-centered.
