Answer:
Any given experiment has numerous control variables, and it's important for a scientist to try to hold all variables constant except for the independent variable. If a control variable changes during an experiment, it may invalidate the correlation between the dependent and independent variables.
Explanation:
The high desert is high, and the low desert is low. this is the difference
Answer:
The correct answer will be option-C
Explanation:
The genome size is the total amount of DNA present in the organisms which includes both coding and non-coding sequences. The genome size is measured in the C-value.
The gene complexity is the complexity in the DNA of an organism which arises due to gene duplication and other mechanisms.
The gene complexity does not show correlation with the size of the organisms which is expected that the larger eukaryotes will have a larger genome size. This is known as the C-value Paradox.
In the given question, since the yeast contains 13 MB, Humans contains only 2,900 Mb whereas a plant of Lily family contains about 120,000 Mb which shows that the lily should be the largest eukaryote which is not the case.
Thus, Option-C is the correct answer.
Answer:
The overall purpose of the light-dependent reactions is to convert light energy into chemical energy. This chemical energy will be used by the Calvin cycle to fuel the assembly of sugar molecules.
To create ATP and NADPH to be used in the calvin cycle.
Explanation:
Hoped I helped please mark me brainliest!!
Answer:
a)Difference in physical state observed:
The difference between the two carrots is that the carrot in the plain water appears bigger or slightly swollen while the carrot in the salt water appears smaller and has shrank in length and slightly in width.
b)Process involved that has caused the changes:
The process that has taken place is osmosis.
c)Why has the process occured:
The process occurs due to the semi-permeable membrane of the cells of carrots that allow water either in or out of the cells.
In the plain water, the process that takes place is endosmosis where the cells of the carrot draw in water and hence the carrot increases in mass. The carrot in the salt water, on the other hand, experiences exosmosis, where water is drawn from the carrot's cells and the carrot becomes dehydrated and shrinks in length and width.
d) Beaker 1 : Water
Beaker 2 : Sugar Solution
e) example of endosmosis is absorption of capillary water from the soil by the root.
another example of endosmosis is is entrance of water in the xylem vessel from the soil by the root.
