The molecules of DNA are
__
so that each cell gets the same directions.
Answer:
Nucleotides
Explanation:
DNA structure
DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code

what is the step in the cell cycle that insures genetic continuity
Answer:
As mitosis ends, each developing daughter cell receives one set of chromosomes. The nuclear membranes return as the cell divides through the process of cytokinesis. In this way, mitosis ensures genetic continuity across generations of cells.
Animals are a more complex life form than plants. What did plants do that allowed for animal life to develop? *
plants make oxygen which animals use to breathe
plants make carbon dioxide which animals use to breathe
plants make water which animals use to swim in
plants make sunlight which animals use to make vitamin D
I'm not sire if it's a single question answer but it looks like it's "A"
humans and animals make carbon dioxide which plants take in
plants don't make water, the water cycle "makes" it
and plants don't make vitamin D or sunlight

There is higher abundance of lighter elements in the universe than heavier elements.
which sourfe of evidence supports that statement
Cosmic Microwave Background Expanding Universe Universe Composition
Answer:
Due to its formation in the supernova nucleosynthesis.
Explanation:
The higher abundance of lighter elements in the universe than heavier elements occurs due to its formation in the supernova nucleosynthesis. The lighter elements such as hydrogen and helium are present in abundant amount and formed in supernova nucleosynthesis as compared to other heavier elements which are formed through other events. The lighter elements occupy less volume and space as compared to heavier elements which is also a reason for their abundance.

Iceland is a natural laboratory for observing sea-floor spreading. Here, the rate of plate motion is about 2.5 cm per year. Predict how Iceland will change in one million years as a result of plate tectonics. Explain your reasoning.
Answer:
25000 meters.
Explanation:
Iceland will change into parts in one million years as a result of plate tectonics. If the rate of plate motion is about 2.5 cm per year so after one million years the Iceland divides and moves away from one another at a distance of 25000 meters so we can say that both Islands are present at different locations and at a large distance from one another.
AS per the observation, change in one million years as a result of plate tectonics in the islands the correct answer is 25000 meters.
Iceland will extrude into components in 1,000,000 years because of plate tectonics. If the charge of plate movement is ready 2. 5cm in line with 12 months so after 1,000,000 years Iceland divides and movements far from each other at a distance of 25000 meters so we are able to say that each island is a gift at distinctive places and at a big distance from each other.
What is Iceland?Iceland is well-known for being known as the Land of Fire and Ice due to its volcanoes and glaciers. It is dotted with herbal wonders including The Blue Lagoon and Dettifoss Waterfall. Iceland is likewise regarded for its wealthy cultural history, Norse mythology, folklore, and having no reputable own circle of relatives' names.
Thus it is clear that Iceland will change in one million years as a result of plate tectonics by 25000 m.

Explanation:
Answer:
C.Noncoding DNA
Explanation:
''Noncoding DNA does not provide instructions for making proteins. Scientists once thought noncoding DNA was “junk,” with no known purpose. However, it is becoming clear that at least some of it is integral to the function of cells, particularly the control of gene activity.

whould you be able to observe the DNA of a single cell?
Answer:
All living things have DNA: the chemical instructions on how to make a living thing, from humans to strawberries. Many people assume that because DNA is so small, we can't see it without powerful microscopes. But in fact, DNA can be easily seen with the naked eye when collected from thousands of cells.

What is meant by reflex-action ? With the help of a labelled diagram trace the sequence of events which occur when we touch a hot object.
A reflex, or reflex action, is an involuntary and nearly instantaneous movement in response to a stimulus.
A reflex is made possible by neural pathways called reflex arcs which can act on an impulse before that impulse reaches the brain.
