multicelular organism.
C: cells are considered the basic structural unit
D: Cells are found in every living thing
Answers
B: That is NOT true; some cells (but not ALL) perform the same functions but most do different specific jobs
C: That is NOT true, ATOMS are the basic structural unit, not cells. Cells are in every living thing, however, not in every structural thing
D: YESSSSSS!
Overall answers:
A and D
The statement that is true about cells are;
- cells come in different shapes and sizes
- cells are considered the basic structural unit
- cells are found in every living thing
- cells are not limited to only a particular size, they have various size and shapes, this is because each cell perform a specific function and as such, they tend to have a different sizes
- cells are considered the basic structural unit of all living things, both plants, and animals, they both depend on cells to survive
- cells are found in every living thing(plants and animals) they perform vital functions

Variation allows some individuals within a population to adapt to the changing environment. Because natural selection acts directly only on phenotypes, more genetic variation within a population usually enables more phenotypic variation.
Which of the cells are involved in graft rejection?
Answers
The immune response to a transplanted organ consists of both cellular (lymphocyte mediated) and humoral (antibody mediated) mechanisms. Although other cell types are also involved, the T cells are central in the rejection of grafts. The rejection reaction consists of the sensitization stage and the effector stage.

Receptors are needed for which type(s) of cell signaling?
Answers
Answer:
Cell-surface receptors are involved in most of the signaling in multicellular organisms. There are three general categories of cell-surface receptors: ion channel-linked receptors, G-protein-linked receptors, and enzyme-linked receptors.
Cells contain proteins known as receptors, which bind to signaling molecules and cause a physiological response. Different receptors recognize different molecules.
What are receptors?Receptors are proteins, typically cell surface receptors, that bind to ligands and cause immune system responses.
Cells contain proteins known as receptors, which bind to signaling molecules and cause a physiological response. Different receptors recognize different molecules.
Insulin receptors bind insulin, dopamine receptors bind dopamine, nerve growth factor receptors bind nerve growth factor, and so on.
Thus, due to this, receptors are needed for cell signaling.

Explain a wedge and give 3 examples.
Answers
Answer: A wedge is basically an incline plane. Often portable used for many purposes
Explanation: A wedge is a double inclined plane such that the two sloping surfaces taper to form either a sharp edge or a pointed edge. For example, a knife, an axe etc.
In a few cases, the number of inclined planes used can be more than two as well. In such cases, the sloping surfaces generally taper to form either a very sharp or a pointed edge to split or pierce materials. For example, pins, nails etc.

The oceans are primarily composed of carbon and hydrogen elements.
What are elements?An element is a substance that cannot be broken down into a simpler format. They are distinguished by a unique atomic number. The elements are organized by their atomic number in the periodic table, which highlights elements with similar properties.
The six elements found in all organisms are carbon, hydrogen, nitrogen, oxygen, phosphorus, and sulfur; collectively called biological elements and shown as the acronym CHNOPS. These elements can bond with each other as well as other elements to create molecules.
Four elements—carbon (C), oxygen (O), hydrogen (H), and nitrogen (N)—make up 96% of living matter. Most of the remaining 4% of an organism's weight consists of phosphorus (P), sulfur (S), calcium (Ca), and potassium (K).

If someone has a heavy weight on his or her chest, explain why after a short time it becomes difficult to breathe, even though the person’s mouth and nose are not affected
Answers
Answer:
When you breathe, air flows from your nose or mouth to your lungs, the lungs expand to allow the air in, and then they contract to remove the air from your body, then you exhale that air.
Then you can see that in the breathing process, your lungs need to expand. If you have a heavy weight on your chest, then the amount that your lungs can expand is really small, then the amount of air that they can have is smaller than normal. This is why is harder to breathe when you have a heavy weight on your chest.

Efforts to reduce pollution began occurring later in the century. If pollution near factories was reduced, what would happen to the color of the moths? Explain your answer.This would happen because
Answers
Answer:
moths would begin becoming lighter as the pollution is reduced
Explanation:
The color of the moths would begin becoming lighter as the pollution is reduced. This is because during the time of high amounts of pollution industrial melanism takes place and the moth's pigmentation becomes a darker tone. This is so that the moths are able to blend in better with its surroundings and survive. Pollution causes sulphur dioxide gas and dark soot deposits which have a greyish dark tone, thats why moths pigmentation turns darker. With pollution reduced moths need a lighter colored pigment to blend into lighter colored objects such as trees and leaves.
The color of the Moths will become lighter as a result of this due to the effect
pollution has on its color.
Industries and factories make use of fuel and when it is burned in generating
sets and other equipment it produces the compound known as Nitrogen
oxide.
The Nitrogen oxide has a brownish color which goes into the atmosphere
where the moths fly in thereby contact with the gas darkens the color to
shades of brown. A reduction in the discharge of the gas will lead to it
becoming lighter.

In 2006, an Ethiopian researcher announced the discovery of well-preserved 3.3 million-year-old fossil of a young female hominid. Refer to Figure (F) below. Considering the Hominid trend of evolution, choose which skull would most likely be that most primitive of the three.
Answers
Answer:
Skull three
Explanation:
the backlining is in more, and the jaw moves out more, resembeling that of a more gorilla like creature
It sounds like the description is referring to a hominid with a more pronounced facial structure, similar to that of a gorilla. This may indicate a more primitive stage of hominid evolution, as earlier hominids had more pronounced facial features and a more protruding jaw than later, more advanced hominids.
What is the basic evolutionary changes in the group mentioned ?As hominids evolved over time, their facial features became more refined, and their jaw became less protruding as they adapted to a diet that relied less on tough, fibrous vegetation and more on softer, cooked foods. This adaptation allowed for the development of a larger braincase and a more upright posture, both of which are hallmarks of later hominids such as Homo erectus and Homo sapiens.
It's worth noting that the evolution of hominids is a complex and ongoing area of research, and new discoveries and interpretations of existing evidence may change our understanding of the evolutionary timeline and the characteristics of different hominid species.
Over the course of hominid evolution, several important changes occurred that distinguish hominids from other primates. One of the earliest changes was the development of bipedalism, or the ability to walk on two legs. Bipedalism allowed hominids to free their hands for tool use and other tasks, and also facilitated the long-distance travel needed to explore new environments.
