Answer:
The genetic material in the sperm combines with the genetic material in the egg to create a new cell that starts dividing rapidly. You're not actually pregnant until that bundle of new cells, known as the embryo, travels the rest of the way down the fallopian tube and attaches itself to the wall of your uterus.
Explanation:
The answer is:
Echinodermata
The word echinodermata is Greek which literally means "Spiny Skin". Echinodermata is a phylum under kingdom animalia. Not all of them have spiny skins, but most of them do. Other characteristics would be their radially symmetric body. They have appendages that grow outward from the center. Examples of echinoderms would be sea stars and sea urchins.
The statement is - True.
The five main factors that determine the weather at a certain place are the:
- geographic location/latitude
It determines the amount of sunlight, as well as the concentration of sun rays, which directly influences the temperature.
- altitude/height above sea level
The lower the place the warmer it is, the higher the place the colder it is, it is a simple rule that applies for all places on the planet, compared with places in their surroundings.
- ocean currents/large lakes
The ocean currents can bring cold and dry or warm and wet air masses, depending on what kind of an ocean current it is. The water also contributes to a more stable weather, with more moderate temperatures because of the thermal properties of the water to cool of and warm up slower than the land.
- winds
The air masses can bring cold and dry or warm and wet weather, so they influence the temperature and precipitation of a place.
- topography
Determines how much a place is exposed to the sunlight and the movement of the air masses.
This answer is TRUE !! Hope this helps you out a little :)
Answer:
R = 16mm/y
Explanation:
Modern Spreading Rate (R) = distance the seafloor moved in km (d) / age in million years (t)
R = d/t
To calculate it in millimeters per year we need to convert it:
<em>1 km = 1000 m
</em>
<em>1 m = 100 cm
</em>
<em>1cm = 10mm</em>
<em>1 km = 1,000,000 mm </em>
The problem states that in 150 million years, there is a distance of 2400 km.
if 1 km ------- 1,000,000 mm
2400 km-------X = 2400,000,000 mm
If 1 million years -------1,000,000 years
150 my----X = 150,000,000 years
R = d/t
R = 2400,000,000 mm/150,000,000 y.
R = 16mm/y
