Answer: SECONDARY CELL WALL.
Explanation: When cell wall grow,it becomes thickened,then it further deposits new layers of a different material (different from that of the primary cell wall) from where secondary cell wall is formed.
This secondary cell wall is made up of cellulose,hemicellulose,and lignin.
They function in providing additional strength,support, rigidity to cells and the larger plant.
Answer:
There should probably be some proof in the information above, but the mass would be lost through excretion, respiration, sweating, and movement
Explanation:
Independent variable: FERTILIZER.
This is the variable that you think affect your dependent variable and so you change it and use different types of it to confirm your prediction.
Dependent variable: COLOR.
That is the variable you are interested in.
Hypothesis: THE TYPE OF FERTILIZER USED IN CULTIVATING HYDRANGEA FLOWER AFFECT THEIR COLOR.
An hypothesis is a generalized statement which predicts the relationship between the variables you are examining.
Control group: THE GROUP THAT DID NOT GET ANY FERTILIZER
The control group is the group that does not receive any treatment.
Experimental groups: THE GROUPS THAT RECEIVED FERTILIZERS.
The experimental group is the group that receives treatment.
Constants: TYPES OF SOIL USED, MORNING SUNLIGHT, WATER AND THE NO OF DAY THE EXPERIMENT LAST.
The constants are the inputs into your experiment which you give to all the groups.
The obligate aerobes need oxygen for their survival, while the obligate anaerobes do not. The obligate aerobes are the species that attain the energy for the process of aerobic respiration with the help of oxygen as the ultimate electron acceptor for the electron transport chain.
On the other hand, obligate anaerobes are the species, which get poisoned by the usual levels of atmospheric oxygen, and thus, get killed in the existence of oxygen.
Fungi should be the answer.
