An engineer made a model of a ship to help him think about how it works ha made sure that some characteristics of the ship were accurately represented but he did not include all of the ships characteristics in his model is it okay that he ignored some of the ships characteristics
Answer:
Yes it is ok
Explanation:
This usually depends on what the engineer is trying to accomplish or learn. For example, if the engineer is simply trying to understand how the architecture floats or cuts through the water then he does not need to model the engines or other unnecessary characteristics. On the other hand, if the engineer wants to understand how the engine provides power to the entire ship then he would need to model the engine and all the connected parts but not the outer exterior of the ship. Therefore, it is ok that he did not model the ship completely as long as it provides the information needed.

B)The fused bones of the skull lessen the impact on the brain.
C)The spongy bones of the skull cause the ball to bounce off the head.
D)The joints in the skull move to prevent the football from hitting the head.
Answer:
B- The fused bones of the skull lessen the impact on the brain.
Explanation:
The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles.
Hope this helps!
The fused bones of the skull lessen the impact on the brain and help prevent injury to the brain.
What is the structure and function of the skull?
The skull consists of 22 bones in most adult specimens, and these bones come together via cranial sutures. The function of the skull is both structurally supportive and protective. The skull will harden and fuse through development to protect its inner contents: the cerebrum, cerebellum, brainstem, and orbits.
Does the cranium protect the brain?
Cranium. The eight bones that protect the brain are called the cranium. The front bone forms the forehead. Two parietal bones form the upper sides of the skull, while two temporal bones from the lower sides.

First Blank: Taiga
Second Blank: Tropical Rain forest
Third Blank: Desert
Explanation:
Process of elimination
1) we're given 4 answer choices but only three blanks. A tropical dry forest is not a thing so we know that one can't be it.
2) To be honest, I didn't know the first one off the bat, so I moved to the second blank and could easily tell it was the rain forest
3) The last blank was also obvious, being that desert climates are quite well known
4) So that left me with Taiga which I used for the first blank

Which scenario breaks the law of segregation? a gamete contains the father’s allele the gametes produced each have 1 allele after meiosis II a gamete produced has 2 of the same alleles after meiosis II the gamete fertilized has the dominant trait
Answer:
The answer is c a gamete has two of the same alleles after meiosis 2
Explanation:
I took the test
The scenario that breaks the law of segregation is "a gamete produced has 2 of the same alleles after meiosis II".
LAW OF SEGREGATION:
The law of segregation as proposed by Gregor Mendel states that the alleles of gene will separate into gametes after meiotic division. The separation occurs in such a way that each gamete have only one allele of a gene after meiosis. For example, if a gene Aa undergoes meiotic division, the law of segregation explains that each gamete will contain either A or a in an equal proportion. Based on the law of segregation, two alleles of a gene cannot be present in each gamete after meiosis II. Therefore, the scenario that breaks the law of segregation is "a gamete produced has 2 of the same alleles after meiosis II".Learn more: https://brainly.com/question/235475?referrer=searchResults

Answer:
horse and donkey.
Explanation:
their bodies are similar. they also sound the same
Of the mentioned options, horse and donkey will have the fewest differences in the sequences of amino acids.
What is the similarity between horse and donkey?Both the horses and donkeys look very similar. Both the species belong the genus Equus. Both the species exhibit various physical similarities. Both are hoofed mammals, and four-legged. They both have large ears, long faces and long backs with tails at the terminal of them.
The ears and eyes in both the species are aligned in similar locations, and they both possess manes running through the tops of their necks. Both the species are social creatures.
