Answer:
Germinal disk (blastoderm) -- a small, circular, white spot (2-3 mm across) on the surface of the yolk; it is where the sperm enters the egg. The nucleus of the egg is in the blastodisc. The embryo develops from this disk, and gradually sends blood vessels into the yolk to use for nutrition as the embryo develops.

Can a renewable resource become a nonrenewable resource? If so, give an example. (1 point)
Yes, a renewable resource, such as natural gas, can get used up faster than humans extract it from the Earth.
Yes, sunlight is a renewable resource but only during the day. At night, solar power cannot be generated, so during that part of the day it is a nonrenewable resource.
Yes, a renewable resource, such as fish, could go extinct if humans consume them faster than they reproduce.
No, renewable resources can never become nonrenewable.
Answer:
If mismanaged, renewable resources will become non-renewable.
Explanation:
For example: Groundwater can be over-pumped. If you burn a tree (plant) and don't plant another one.
Yes, a renewable resource can become a non-renewable resource.
What is a renewable resource?
A renewable resource is a natural resource which will replenish to replace the portion depleted by usage and consumption, either through natural reproduction or other recurring processes.
What is a non-renewable resource?A non-renewable resource is a natural resource that cannot be readily replaced by natural means at a pace quick enough to keep up with consumption.
Renewable resources can become non-renewable resources if they are used up faster than they can be replenished. Water is a common example of a renewable resource. If the water is used in a huge and big amount by every people of the earth for unnecessary purposes, then day by day the stock of the water level below in the earth will decrease and gradually the water will turn into a non-renewable resource.

Alien Taxonomy Project IN THE YEAR 2525 Humans, after hundreds of years of constant effort, have successfully polluted all bodies of water on Earth. As a result, almost all previously known species of plant, animal, and other life have become extinct. Through natural selection, genetic engineering, and selective breeding programs, a portion of the Earth has been successfully repopulated. The following organisms are all that remain: 1. Photosynthetic sun-basking sharks. Their green fins have chlorophyll to convert sunlight to energy (autotrophs). 2. Chemosynthetic goldfish that convert pollution to food (autotrophs). 3. Aquatic humanoids whose main diet is aqua-wheat and basking sharks. They have fins instead of legs (heterotrophs). 4. Aqua-wheat: one of the few plants that remain, it is similar to algae. 5. Terrestrial Humanoids with 4 arms, their diet consists of butter-roaches and fuzzy hamsters. 6. Tentacled aqua humanoids, they only feed on aqua-wheat and have tentacles for arms and legs. 7. Cockroaches that feed on humanoid waste. 8. Giant Aqua-spiders that live in water and feed on goldfish and basking sharks. 9. Green-haired rats that are photosynthetic. 10. Parasitic mosquitoes that feed off any humanoid 11. Ten-legged fleas that live on the photosynthetic rats and drink blood. 12. Poison Grass - this plant is a hybrid between grass and poison ivy. The plants are toxic to almost everything (autotrophs) 13. Fuzzy hamsters with green hair that use the sunlight to make their food, thought to be related to the rats. 14. Butter-roaches: genetic engineering created these butterfly-like creatures from cockroaches. Butter- roaches eat poison grass. YOUR ASSIGNMENT: 1. As an alien taxonomist, it is your responsibility to classify these existing organism types. Create a taxonomic scheme using only kingdom, phylum, genus, and species. The intermediate categories have been eliminated since the total number of species has been drastically reduced. (Two Kingdoms are recommended). Each new group needs a name and a de

How are organisms classified at each taxonomic level?The recent taxonomic system now has 08 stages in its hierarchy, from down to up , they are: species, genus, family, order, class, phylum, kingdom, domain. Thus species are grouped within genera, genera are grouped within families, families are grouped within orders, and so on.

On the island of Hawaii, Keanu notices that the sand on the beach is black, the same color as the rock formations on the island. Keanu realizes the sand used to be part of the rock formations. How did material from the rock formations turn into sand?
Answer:
It turned into sand from erosion. Or to break it down specifically the waves constant crashing on the rocks broke it apart little by little and the pieces of rock that fell into the water were tossed and bashed around even more until they broke into such fine pieces of rock, which is then called sand. The reason that the color of the sand matches that of the surrounding rock is because during this process it doesn't effect the original color of the rock.
Explanation:
Answer:
the answer is the weather
Explanation:
Magma rises to Earth's surface, such as through a volcanic eruption, where it cools and hardens into igneous rock. On the surface, weathering and erosion break down the igneous rock into pebbles, sand, and mud, creating sediment, which accumulates in basins on the Earth's surface
