Answer:
The correct answer would be - True.
Explanation:
In several organisms have structures, has no apparent role in the particular species and are residual parts from a past ancestor, but these structures were fully functional in the ancestors of the species. These structures are called vestigial structures or organs.
The example of such structures are, wings of the flightless birds, appendix of human and many other, all these structures has no function in the body of the individuals of the particular species but is fully functional in ancestors.
Thus, the correct answer is - true.

B. Testing a hypothesis
C. Communicating your findings in a journal
Answer:
A. Making an observation
Explanation:
Before you can communicate findings, you first need to have findings. And before you can test a hypothesis, you first need to come up with a hypothesis, which can be done by first making an observation.
What is a disadvantage of a 2D model of the digestive system?
Answer:
The disadvantage of 2D model of the digestive system is that it decreases cell to cell interaction and it is not a very important biological model.
Explanation:
The 2D model does not show quality similarity and resemblance to the main digestive system and also fail to reveal the interaction of cell surfaces of each other, it does not provide the quality detail of biological systems in digestive systems and this model is not very important or relevant biological model because It does not provide quality detail.
What happens to blood once oxygen hits and why?
Answer:it changes colour
Explanation:
When blood passes through the lungs, the hemoglobin absorbs oxygen from the air we breathe and turns bright red. Our heart then pumps this blood all over the body. When it reaches its destination, the oxygen is released from the hemoglobin, and the hemoglobin turns a darker red-brown.
Which statement describes a similarity between asexual reproduction and sexual reproduction? Both processes involve fertilization. Both processes involve cell division. Both processes produce genetically identical offspring. Both processes require two parents.
Answer:
The correct answer is B. Both processes involve cell division.
Explanation:
Both asexual and sexual reproduction involve cell division; they are means of creating offspring.
Only sexual reproduction involves fertilization, so we know that choice A is incorrect. Only asexual reproduction produces genetically identical offspring, so choice C is also incorrect. Finally, only sexual reproduction requires two parents, so choice D is not correct either.
This leaves us with choice B as the correct answer.
Hope this helps!
Answer:
Answer is B
Explanation:
I got 92%, so there's a 2/25 chance that this answer is wrong, pls tell me if it's wrong
1) A class collected water samples from a nearby pond and wants to observe the samples for
microorganisms. Which microscope would be the most appropriate for the students to use?
A. Dissecting microscope
B. Compound light microscope
I
C. Transmission electron microscope
D. Scanning electron microscope
Answer:
Compound light microscope
Explanation:
This is the ideal microscope because it requires the passage of harmless beam of light through the specimen.Since the pond contain living creatures this is best to use.
C and D both require the transmission of beam of electrons through a sample. D depends on the reflection of the electron after scanning the specimen surfaces and sent this to the lenses of the observer.(C)involved the passing of the beam of electrons through the specimen the interaction of the electrons with the atoms in the specimen(,therefore in both cases these specimens can not be wet and living.
The specimen should be dry in both cases and therefore non -living ,because the chamber for the specimen must be a vacuum,and living organism can not survive in the vacuum. Thus pond water can not be used as specimen because the specimen in the water but me be living.

Which list below correctly shows the levels of organization in an organism from left to right? organs, tissues, systems, cells, organisms tissues, cells, systems, organs, organisms organisms, cells, tissues, organs, systems cells, tissues, organs, systems, organism
Answer:
Cell-tissue-organ-organ system and finally an organism
Explanation:
The list that correctly shows the levels of organization in an organism is from left to right is :
Cell --> Tissue ---> Organ ----> System -- > Organism
The cell is the basic unit of life, a group of similar cells performing similar functions make up a Tissue. While tissues perform more specialized functions when compared to cells.
Tissues make up an organ while a system like Digestive system , respiratory system, reproductive system are made up of a group of organs performing similar functions. The collection of all systems make up an organism.
Hence we can conclude that the list that correctly shows the levels of organization in an organism is from left to right is Cell --> Tissue ---> Organ ----> System -- > Organism

What's the independent and the dependent variable ??
Answer:
ruler
Explanation:
Ancient Greek philosophers spent lots of time thinking about science and imaging explanations for the natural world. What part of the scientific process did they need to do
Answer:
Experiments
Explanation:
The ancient Greek philosophers spent more time philosophising and thinking about scientific explanations to phenomena in the natural world.
How ever, they relied solely on reasoning while attempting to explain scientific observations. Contemporarily, science is highly empirical. The scientific process can only be complete when scientific observations are subjects to rigorous experiments in order go determine the actual relationship between variables and provide better explanation for scientific observations.
Hence the ancient Greek philosophers should have used experiments rather than sole reason in proffering scientific explanations to natural phenomena.
Answer:
Experiments
Explanation:
The ancient Greek philosophers spent more time philosophising and thinking about scientific explanations to phenomena in the natural world.

As a scuba diver descends toward the bottom of the ocean, she experiences the sensation of her ears "popping." Based on your observations from the Can Crush Lab, why would this happen?
A. Decreased pressure inside the diver's oxygen tank causes pressure on the diver's ears.
B. Increased pressure inside the diver's oxygen tank causes pressure on the diver's ears.
C. Pressure increases on the diver as the diver descends deeper underwater.
D. Pressure decreases on the diver as the diver descends deeper underwater.
Answer:
C. Pressure increases on the diver as the diver descends deeper in the water.
Explanation:
Due to the pressure of the water on the diver she feels the pressure on her ears. Just like the same feel of going up a steep hill.
