Answer: The blood vessels surrounding your stomach and intestines constrict and the digestive muscles contract. It's that drop in blood flow that makes you feel like winged insects are fluttering around in your stomach.
Explanation:
A large cloud of gas (hydrogen) and dust a nebula begins to collapse
The collapsing cloud begins to spin
The spinning collapsing cloud flattens into a rotating disk
Material in the disk begins to accumulate in the center
As the material coalesces in center, it becomes dense, compresses, and heats up.
More and more material coalesces to form a protostar.
The protostar continuse to accomulate material from the surronding disk and grow.
Eventually, the protostar becomes massive enough, dense enough and hot enough to cause the process of nuclear fusion to begin.
Nuclear Fussion isotops of hydrogen atoms (deuterium, tritium) combine to form helium atoms, energy, and subatomic particles.
Once nuclear fusion begins the protostar's “ignition” to nuclear fusion creates a solar wind that drives remaining gas and dust to the outer parts of the disk.
Then the young star stops accumulating material.
A) Gestation
Gestation is the <span>period of time between conception and birth when a baby grows and develops inside the mother's womb.</span>
Answer:
Explanation:
In the members of the class ascomycetes such as yeast, two haploid yeast cells of two different stains or mating types fuse to form a diploid zygote. Zygote quickly undergoes meiosis or reductional division to form four haploid spores called a tetrad. The tetrad is contained in a sac-like structure called an ascus or fruiting body. Formation of ascus is the characteristic feature of ascomycetes. In the ascus tetrad are not arranged in any specific order. The tetrad are called random or unordered spores. The genetic analysis of the genotypes in the tetrad can tell us about the events during meiosis.
Answer:
genetic information, energy, soil
Explanation:
Germination is the term used to describe the set of steps that allow the development of an embryo within the seed of the plant. The development of this ambrion will result in the emergence of a seedling that will develop and form a very important plant for the ecosystem. In short, germination is the process of transforming the seed into a new plant.
In order for this to occur, the seed needs some factors that degrade its entire development. These factors are genetic information, energy and soil
