Scientific models always A. require memorization
B. have limitations
C. comeplete
D. represent old infortmation

Answers

Answer 1
Answer:

The scientific models always exhibits limitations.  

• All the scientific models exhibit limitations as they are not representative of every possible scenario.  

• Scientific models are not a substitution for experimentation, they can be used in combination with experimentation to further comprehend a concept, process, or event.  

• The scientific models are based on present scientific knowledge and may have to be changed when novel discoveries are made.  

Thus, all the scientific models have limitations, the correct answer is option B.

Answers

The statement "white blood cells can leave the blood circulatory system" is definitely true.

What is the circulatory system?

The circulatory system may be defined as a type of body system that significantly contains the heart and the blood vessels and moves blood throughout the body. This system helps tissues get enough oxygen and nutrients, and it helps them get rid of waste products.

White blood cells can also be known as the soldiers of the body. They can leave the bloodstream and migrates into tissues in the body. White blood cells play an important role in the immune system.

Here the different blood cells have different functions: Some fight intruders such as bacteria, viruses, parasites, or fungi themselves and render them harmless.

Various studies and reports suggested that the white blood cells -- actively open large gaps in the internal lining of the blood vessels, so they can exit through the vessel walls and rapidly get to areas of infection.

Therefore, the statement "white blood cells can leave the blood circulatory system" is definitely true.

Which of the following statements does NOT contribute to the evidence in support of evolution?(A) Sequences of fossils have been found that show a gradual series of changes in form among organisms.
(B) Species thought to be related through evolution from a common ancestor show many anatomical similarities.
(C) The stages of embryological development in animals are quite similar among highly diverse types of organisms.
(D) Similarities in chromosome structure, DNA sequence, and amino acid sequence suggest relationships among organisms descending through evolution from a common ancestor.
(E) The most well adapted individuals do not always produce the most fit offspring.

Definitely option E! This refers to exceptions to the 'survival of the fittest' - but the theory still holds despite these anomalies.

cats generally have gray fur which is caused by a dominant gene. the recessive condition results in orange fur. two heterozygous cats are crossed. what proportion of the offspring will have orange fur if this type of inheritance follows simple mendelian inheritance?

Answers

The answer is 25%.

This is an example of Mendelian monohybrid cross.
If:
A - (dominant) allele for gray fur
a - (recessive) allele for orange fur

Then:
AA - dominant homozygous
Aa - heterozygous
aa - recessive homozygous

The cross between two heterozygous will be:

Parents:            Aa        x        Aa
Offspring:     AA      Aa      Aa       aa

Thus, the offspring will be: 1 out of 4 (25%) dominant homozygous (AA), 2 out of 4 (50%) heterozygous (Aa), and 1 out of 4 (25%) recessive homozygous (aa).
Since the recessive condition results in orange fur, only recessive homozygous (aa) will have orange fur, which is 25% of all the offspring.
If the dominant gene in cats is the one which gives them gray fur and the recessive condition is responsible for orange fur, then two heterozygous cats which would be crossed would have offspring: 

Ff (cat 1) Ff (cat 2)

FF Ff Ff ff

75% of the offspring would have gray fur (big F) and only 25% of the offspring would have orange fur (two small ffs)
