Answer:

Relative dating is the technique to calculate the age of an ancient materials in comparison to another material's age. Layer A is less older, if layer B lies beneath it. Layer A may be 2.5 to 3 million years old.

Explanation:

Before discovery of radioactive carbon dating method, geologists make use of relative dating method in order to determine the age of rock or fossils. The relative dating procedure often referred to as stratigraphy. Though this procedure is not capable of predict absolute age or dating. In relative dating, is mainly based on the fact that the older rock layers will be deeper in respect to the less older rock layer.

Prompt
Orlov [11]

Answer:

Energy in an ecosystem is mainly made by the producers of an ecosystem. The net primary productivity in an ecosystem depends on many factors. Some of them are:

  • Amount of sunlight: The amount of sunlight that the plants and trees might be has basic influence on the primary productivity. Plants and trees receiving enough sun light will be able to make more food for organisms living in that area as compared to the producers which do not receive enough sun light.
  • Soil texture: The soil texture and the availability of nutrients heavily influence the primary productivity of an ecosystem. An area having a soil texture with not enough nutrients will not be able to grow more plants. As a result, the productivity would decrease.

SUNLIGHT
Mazyrski [523]

Answer:

"without light energy from the sun, photosynthesis would still occur" is completely false. Light energy is needed for the light-dependent reactions, or simply the light reactions, of photosynthesis.

"oxygen is an input into photosynthesis, carbon dioxide is an output" is also completely false. It is the opposite.

These statements are true, however:

SUNLIGHT

CARBON DIOXIDE

WATER

MINERALS

OXYGEN

PLANT SUGARS

Carbon dioxide enters the leaves through stomata (tiny holes) in the leaves.

Sunlight is an input, CO2 is an input, water is an input (taken in through the roots, transported through the veins), minerals are a collective input, oxygen is an output (produced during photolysis), and plant sugars are an output (glucose, for an example).

Why is it imprtant for the ova and sperm cell to each contain a haploid number of chromosomes?
Katyanochek1 [597]

Meiosis makes sperm and eggs. ... The result is 4 haploid daughter cells known as gametes or egg and sperm cells (each with 23 chromosomes – 1 from each pair in the diploid cell). At conception, an egg cell and a sperm cell combine to form a zygote (46 chromosomes or 23 pairs).
