B) the model does not show that cells can contain smaller structures inside.
This is true because only a rubber ball was added, indicating that only a nucleus or any one organelle is present in a cell. However, the cell contains more than one organelle from the nucleus, mitochondria, Golgi apparatus, smooth and rough endoplasmic reticulum, ribosomes, and more.
Another possible answer would be D since they model does not show the process of cellular respiration where cells undergo this process to create ATP in the mitochondria.
Answer:
Intelligent Design
Some scientists who are Christians have developed a theory called Intelligent Design to explain the creation and development of life on earth.
However, in my opinion its complete nonsense
Muscular activity of its digestive system distorts the body wall should convince you that the organism is acoelomate.
<h3><u>
Explanation:</u></h3>
An animal that does not have body cavity refers to an acoelomate. It is in contrast with the eucoelomates which are the animals that have body cavity. The acoelomate will not have a cavity which is filled with fluid between the digestive tract and the body. Hence there will be a distortion of body wall by the muscular activity of the digestive system.
Some of the examples of acoelomate are Cnidaria,Porifera , Platyhelminthes, Placozoa ,Gnathostomulida.Nemertina and Mesozoa. The presence of pseudocoelom in which the body cavity will not be lined by the mesodermal cells are the Pseudocoelomate.
Tin, because it has five energy levels with four electrons in the fifth level
.
Explanation:
Tin has an electronic configuration as
1s2,2s2,2p6,3s2,...........4d10, 5s2,5p2
They have four valence electrons in their outer shell
Among the four diagrams given Tin is least reactive because the atomic radius of tin is largest among all four options. Due to large atomic radius electronegativity decreases and hence Tin is the least reactive element among Neon, Chlorine, gallium and tin.
The electronegativity of an element is its tendency to complete its octet by attracting electrons towards itself. Also tin is at the lowest place in the periodic table among all the four mentioned elements, its ionization energy is also low hence less electronegative and least reactive.
In the story and according to Scrooge, the place were poor people work to get their food is the workhouse. It is also the place where Scrooge things poor people must spend their Christmas. Aside from this, he also said that the prison is also a place for poor people during Christmas.
