Answer:

Eukaryotic Cell organelles

Explanation:

A .Plasma membrane:It is made up of phospholipid bilayer with embeded proteins.It protects the various cellular organelles from its exterior envirnnmentt.It is selectively permeable in nature..Due to its nature,the organic molecules,oxygen,water,other nutrients moves in and out through this membrane.The waste materials such CO2 and NH3 exits from this passage.

B. A Mitochondira.It is often called as the energy reservoir of a cell..Its a site of cellular  respiration.In Eukaryotes the respiratory pathways are either aerobic or anaerobic respiration depends upon the nature of a species.The number of mitochondria varies depends the energy requirements to a cell.The mitochondria is membrane bound organelle double inner and outer membrane.These layers are made up of phospholipid bilayers and proteins.The inner is folded called cristae.The regions within the cristae is called mitochondrial matrix here the citric acid cycle .Krebs cycle,glycolysis takes place In over all cycles 38 ATP is generated.

C.A lysosomes: It is absent in plant cells but present in animals cell also termed as waste disposal. Enzymes of lysosomes helps in the breakdown of proteins ,lipids  ,polysaccharides ,nucleic acids and damaged organelles.The lysosomes breaks down macromolecules and contains plenty of enzymes.

D.Endoplasmic reticulum: It’s a flattened sac like structure within the cytoplasm of a cell. It performs various functions but more specifically it synthesizes and modifies and transport proteins. There are two types of ER rough Er and smoothER .The RER synthesize proteins transports by the ribosomes.and the SER synthesize lipids.

When a volcano erupts, such as the Kilauea volcano in Hawaii, what do you think happens to the surrounding ecosystem? Explain ho
Anettt [7]

Answer:

the surrounding ecosystem is nearly or completely destroyed this changes the physical and biological components of the system by killing any biological life and reshaping all structures with magma. this will affect the population by killing anything living haunting life for centuries until new life can start to form such as lichens to break down the hardened rocks nutrients into soil for life

Which of the following does not promote biodiversity
bonufazy [111]
The correct option is INTRODUCTION OF EXOTIC SPECIES;
Exotic species refers to an introduced specie of an animal which is alien to the ecosystem in which it found itself and which has been transported to that ecosystem either intentionally or by accident. Exotic species normally have varieties of effects on the ecosystem to which they are introduced, sometimes the effect will be good and sometimes the effects could be devastating depending on the particular situation. 
Factors which promote diversity include: larger size of the ecosystem, longer growing seasons and climatic stability.<span />

Hypothesis: If the porosity of three soils are tested, then red clay soil will have the lowest porosity.
NNADVOKAT [17]

Answer:

This question is incomplete, based on the given hypothesis, the question is asking to identify the variables (independent and dependent) of the experiment.

*Independent variable: DIFFERENT SOILS

*Dependent variable: Porosity

Explanation:

- Independent variable is the variable that is manipulated or changed by an experimenter in order to effect a response in another variable. In this question, three different soils were used, hence, the SOIL is the independent variable.

- Dependent variable is the variable that responds to changes made to the independent variable. It is the variable being measured in an experiment. In this case, the porosity is the variable being measured, hence, it is the dependent variable.
