What does it mean to be in the same species
Answer:
organisms belong to the same species if they can interbreed to produce viable, fertile offspring. Species are separated from one another by prezygotic and postzygotic barriers, which prevent mating or the production of viable, fertile offspring.
8. Ice erodes rock and deposits sediments to form
Answer:
glacial landforms
Explanation:
Glaciers cause erosion by plucking and abrasion. Glaciers deposit their sediment when they melt. Landforms deposited by glaciers include drumlins, kettle lakes, and eskers.
Answer:
Erosion and Deposition by Ice Key Concept Glaciers shape Earth’s surface by moving rock and sediment. What You Will Learn • As glaciers move, they form a variety of landforms by removing rock and soil. • Glaciers deposit rock material when they melt or retreat. Why It Matters Glaciers have formed many of the landforms on Earth.

Explain why it is necessary that gametes (egg cells and sperm cells) have half the DNA that normal body cells have.
Answer:Gametes are reproductive cells, such as sperm and egg. As gametes are produced, the number of chromosomes must be reduced by half. Why? The zygote must contain genetic information from the mother and from the father, so the gametes must contain half of the chromosomes found in normal body cells.

Cells can be classified into two different categories: prokaryotic and
eukaryotic. Which of the following information is needed in order to
determine if an organism is prokaryotic?
Answer:
Prokaryotes are single-celled organisms belonging to the domains Bacteria and Archaea. Prokaryotic cells are much smaller than eukaryotic cells, have no nucleus, and lack organelles. All prokaryotic cells are encased by a cell wall. Many also have a capsule or slime layer made of polysaccharide.

Answer:
the total resistance is 12 ohms
Amps = 1 amp
Explanation:
resistor in series add so the total resistance is 12 ohms
E=I x R E = voltage, I = amps, R = resistance
12 = I x 12
I=1
1 amp
resistor in series add so the total resistance is 12 ohms
E=I x R E = voltage, I = amps, R = resistance
12 = I x 12
I=1 is the correct answer

a block of wood has a mass of 6 .0 and a volume of 12 .0 CM what is the density Of the block of wood
Brainly will be given
Answer:
[tex]\boxed {\boxed {\sf d=0.5 \ g/cm^3}}[/tex]
Explanation:
Density is equal to mass over volume.
[tex]d=\frac{m}{v}[/tex]
The mass of the wood is 6.0 grams and the volume is 12.0 cubic centimeters.
[tex]m= 6.0 \ g \\v= 12.0 \ cm^3[/tex]
Substitute the values into the formula.
[tex]d=\frac {6.0 \ g}{12.0 \ cm^3}[/tex]
Divide.
[tex]d=0.5 \ g/cm^3[/tex]
The density of the wood is 0.5 grams per cubic centimeter.
A scientist is examining layers of the
earth and tracking information about
animal fossils found in each layer. For
many of the deeper layers there are
consistently large animal skulls but
there is a sudden shift in the skull size in
one layer and they are all much smaller
at that point for the remaining layers
until the earth's surface. What does this
suggest?
This suggests that sudden change that occur to the environment cause a different size animal to become the main species of that area.
Why the fossils of small skull organisms were found?This is because at that particular environment the small skull organisms can survive at that time as compared to big skull animals. The presence of a specific type of fossil in the soil layer shows that the fossil organism live at that time on this area due to the presence of good environmental conditions so we can conclude that environment was good for the small skull organisms at that time.

How is DNA created?(short answer)
Explanation:
For a strand of DNA to form, nucleotides must be linked into chains, with the sugar phosphate groups alternating. DNA is made of the building block chemical called nucleotides. Nucleotides are made up of three main parts, a sugar group, a phosphate group, and some type of nitrogen base. Hope this answers, and is helpful! Have a great day! :))
How important is it for a cell to maintain the same number of chromosomes? Explain.
Answer:
