Explanation:
The Sun and the planets formed together, 4.6 billion years ago, from a cloud of gas and dust called the solar nebula. A shock wave from a nearby supernova explosion probably initiated the collapse of the solar nebula. The Sun formed in the center, and the planets formed in a thin disk orbiting around it. In a similar manner, moons formed orbiting the gas giant planets.

Answer:
When blood clotting is activated, fibrinogen circulating in the blood is converted to fibrin, which in turn helps to form a stable blood clot at the site of vascular disruption.

Can anyone help
Me if y’all know this?
Answer:
62 dg = 0.62 dag
72,448 mm = 72.448 m
0.641 L = 641 mL
10,000 cm = 0.1 km
0.998 dL = 0.0998 daL
78,548 m = 78,548,000 mm
45 hg = 4500000 mg
97,123,582 mm = 97.123582 km
0.00741 kL = 7,410 mL
745 g = 74,500 cg
25 mm = 2.5 cm
0.005741 kL = 574,100,000 cL
Thoroughbreds are an example of a type of horse that results from selective breeding. However, not all thoroughbreds have the traits that are most desired. How is it possible to breed thoroughbreds but not have a horse with desired traits such as a fast runner?
In selective breeding, when crossing individuals that express the desired phenotype but are heter0zygous for this character, their offspring might express the undesired trait.
--------------------------------------
The main goal of selective breeding is to get individuals -plants or animals- with the desired traits. These traits make them better, according to the breeder's interest. The interest is to produce individuals with the same reproductive capability, adaptability, capacity, and general phenotype as the original pure line.
To get a generation of individuals expressing the desired traits, the breeder must select parents that have the characteristics of interest. Many or some animals of the progeny might inherit the desirable phenotype.
In general, pure and almost identical animals with the desired traits are produced after many generations of inbreeding. These are the pure-bred individuals and are the product of many selective crosses.
Pure-bred (true-bred) animals are h0m0zyg0us dominant or recessive for the desirable traits. The progeny of the same line express similar phenotype and performance to the ones of their progenitors.
Many problems are associated with selective breeding and the production of pure lines.
In the exposed example, let us say that the desired trait is running speed and that there is only one autosomal gene that codes for run speed.
the dominant allele F expresses the trait fast runnerthe recessive allele f does not express the trait fast runnerSo, FF and Ff individuals will be able to run fast, while ff individuals will not.
Probably the breeder does not know the genotype of the animals, so this person crosses the horses according to how fast they run -phenotype-. If the breeder wants to get fast runner animals, he/she will only choose horses with this trait, which might be either FF or Ff.
If the breeder chooses two heter0zyg0us individuals, there are 75% of getting horses with the desired trait and 25% of chances to get horses with the undesired trait -h0m0zyg0us recessive genotype ff-.
The breeder needs many generations of inbreeding to get only horses that are fast runners.

5-7 sentences that describe the life cycle of a star
Answer:
The accurate existence of a star depends extremely on its size.
Explanation:
The mass decides the life cycle of a star whereas the central sequence star shines, hydrogen in its core is turned into helium by nuclear fusion. Meanwhile, the hydrogen supply in the core begins to run out, and the star is no longer producing heat by nuclear fusion, the core enhances unstable and contracts.The stars are grown in clouds of vapor and dust which are identified as Nebulae. The nuclear reactions toward the center of stars produce sufficient energy to get them to shine brightly for several years. Sun is the nearest star to the earth. Numerous stars are visible to the bared eye from Earth through the night, resembling twinkling dots due to their enormous distance from the Earth.Learn more about life cycle of star, refer:

describe the human population growth curve over the past 10,000 years, and identify the type of population growth curve it represents
p.s I will give brainless
Explanation:
Global human population growth is around 75 million annually, or 1.1% per year. The global population has grown from 1 billion in 1800 to 7 billion in 2012.
Although the direst consequences of human population growth have not yet been realized, exponential growth cannot continue indefinitely.
In the late 1970s, China’s “one-child” policy tried to control population growth, but restrictions were relaxed in the early 2000s.
In response to injury, cell fragments called platelets get activated to induce clotting. Activated platelets release factors that can in turn bind to specific membrane receptors on nearby cells. What type of signaling would this be considered
Answer:
Activated platelets express negative phospholipids on the exterior leaflet of their cell membrane, release vasoactive compounds, release cytokines, and release growth factors.
When an injury causes a blood vessel wall to break, platelets are activated. They change shape from round to spiny, stick to the broken vessel wall and each other, and begin to plug the break. They also interact with other blood proteins to form fibrin.
Platelets contribute their hemostatic capacity via adhesion, activation and aggregation, which are triggered upon tissue injury.
