Difference between hypothesis and prediction examples
Butoxors [25]

A prediction is a guess what might happen based on observation.

Here are some steps to think about to make a dependable prediction:

Collect data using your senses, remember you use your senses to make observations.

Search for patterns of behavior and or characteristics.

Develop statements about you think future observations will be.

Test the prediction and observe what happens.


A hypothesis is a possible explanation for a observation or problem that can further be tested by experimentation. Hypothesis' are also known as educated guesses.

Here are the steps to form a hypothesis:

When developing a hypothesis think about any observations or previous knowledge you know about the variables.

Express what you think will be the effect of changing one of the variables (Independent variable) on the other variable you expect to change (Dependent variable).

Develop your hypothesis using a statement.

A example of a hypothesis statement would be, As the (independent variable) ( describe how you would change it) , then the (dependent variable ) will (describe the effect)

A pea plant with round seeds (RR) is crossbred with another pea plant with wrinkled seeds (rr). What is the probability of the o
vichka [17]

Answer:

0%

Explanation:

The cross of a pea plant with round seeds (RR) with another pea plant with wrinkled seeds (rr) is shown as under :

P              RR  x   rr

F1          Rr    Rr    Rr   Rr

It is clear from the cross above, all the 4 probable progenies in filial 1 (F1) generation will be heterozygous with Rr genotype. Not even a single progeny will have homozygous recessive genotype which is responsible for producing wrinkled seeds. Also, even though the genotype of the progenies will be Rr not RR yet phenotypically they all will have round seeds i.e. they will show dominant trait. The reason behind it is that one of the alleles R which is responsible for dominant trait will mask the expression of recessive allele r. So, wrinkled phenotype which is a recessive trait will not be observed in any of the progenies.

How is homeostasis maintained through blood sugar project
marin [14]

Answer:

Homeostasis is the process to maintain balance in body.  Homeostasis in sugar can be maintained by two pancreatic hormones-

1-Insulin

2-Glucagon

Explanation:

Insulin - secreted by beta cells of islets of langerhans in pancreas. It lowers blood sugar level when high concentartion of sugar is present in blood. It converts sugar to glycogen by the process of GLYCOGENESIS. It allows insulin receptors on hepatic cells to absorb glucose molecules from blood. To lowers the glucose concentration in blood stream.

Glucagon - secreted  by alpha cells of pancreas. It increases blood sugar level when sugar level is low in blood. Glucagon converts glycogen into glucose. Stored glycogen can be reconvert into glucose molecules with help of this hormone. this process is known as glycogenolysis. When blood sugar concentration is  low in blood stream.

<em>With the equilibrium between these two hormones homeostasis is maintained through blood sugar project in body</em>

sveta [45]

Answer:

Patient's sex.

Explanation:

Trauma triage and transport process main aim is to provide the proper facility to the injured patient so they can easily reach at the trauma center. Emergency medical services also plays an important role.

Different rules and guidelines have been implemented in the  trauma triage and transport. The physiology of the patient is determined and proper medical facility is provided to the patient. The patient sex is not determined and keep not in consideration in the guidelines.

Thus, the correct answer is option (B).
