What's the difference between a hypothesis and a theory?

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.

Answer:

multicellular organism

Explanation:

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.

Explanation:

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.

So, 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.

ADVANTAGES:

Bacteria are involved in production of many food products such as yogurt, cheese, pickles, etc.

Bacteria break down waste material so that our environment is not permanently cluttered with garbage, dead bodies, etc.

Bacteria are responsible for the production of important essential compounds that are necessary for life such as vitamin K production by E. coli in the gut

DISADVANTAGES:

Some bacteria cause infections or produce toxic substances that are a threat to life and/or health.

Bacteria cause spoiling of food so that it does not keep as long as we may desire.

Some bacteria may cause infections of plants, threatening our food supply or ornamental plant.

The properties that allow this are the carbon's four valence electrons, and the fact that they can bond with other carbon atoms.

Answer:

Show the picture better for people to see

Explanation:

Answer:

between an animal cell and a plant cell there are some parts that are similar and carry out the same function like:

both have a cell membrane which selects what goes in the cell.

both have cytoplasm which holds the protoplasm(the living part of the cell)

both have a nucleus which carries out all cell activities and holds threads of DNA called chromosomes

both have a mitochondria which is the power house of the cell

both have golgi bodies which modify and carry proteins from sites of synthesis to sites of reaction

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.

whats the question

Explanation:

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
