Organelles such as mitochondria and the endoplasmic reticulum have membranes that compartmentalize reactions and other metabolic processes. To
function properly, the organelles must move substances across their membranes.
Which of the following statements describes a feature shared by mitochondria and the endoplasmic reticulum that increases the efficiency of their basic
functions?
A
They have rigid, nonfluid membranes.
B
They have highly folded membranes.
С
They have membranes composed of many carbohydrates,
D
They have double membranes, with one membrane enclosed within the other
Answer:
b
Explanation:
The first step of the scientific process is
A. Making an observation
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.

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

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.

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.
Describe two examples of non-living things that have one or more of these characteristics of life.
Living organisms are distinguished from non-living things as they have the property of life.
Living organisms have important features that differs them from non-living things. For example., growth, reproduction, movement, sensitivity and death are few among many.
Growth is the unique property where a living organisms grows in size and volume.
Reproduction is another important characteristic where a living organism reproduces one of its own kind.
Living organisms move from one place to another which is not observed in non-living things.
Living organisms are sensitive to stimulus from the outer environment and respond accordingly. The stimulus can be touch, smell, temperature etc.
Living organisms have the characteristics of aging and senescence. They ultimately die.
Therefore, living organisms are different non-living things in many distinct ways.

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.

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
