the excretory system removes waste from the body and removes waste from the blood. The digestive system breaks down the the food you eat into nutrients that provide energy and building materials for cells. The digestive and excretory system work together to process the food that you eat.
Answer:
I believe it's C? not fully sure, sorry if I get it erong6
Answer:
See the explanation below
Explanation:
From the balanced equation of photosynthesis:
6 moles of CO2 is required to produce 6 moles of oxygen.
Assuming that 5.2 g of CO2 reacts with water,
mole of CO2 = mass/molar mass = 5.2/44.01 = 0.1182 mole
Hence,
0.1182 mole of CO2 will yield 0.1182 mole of O2.
Mass of oxygen that will be produced from 5.2 g of CO2:
= molar mass of O2 x mole of O2
= 0.1182 x 16
= 1.9 g of O2.
<em>Note: Because the mass of CO2 is in two significant figure, the final answer was adjusted to be in two significant figure. The mass of oxygen can be computed depending on the mass of CO2 involved.</em>
Answer:
Oxygen
Explanation:
Oxygen atoms in water attracts more electrons compared to the hydrogen atom because it has two pairs of unshared electrons, this makes water distribute charges asymmetrically resulting in a bent shape.
<u>Answer</u>:
If I were studying the causes of cancer, the topic which might interest me is "The topic of spindle-fibre structure.".
<u>Explanation</u>:
In cell division, the accurate segregation of chromosomes is coordinated with the complex structure of spindle fibre in cell. The mitiotic structure is consisted of two apparatus, one is centrosomes and the other is microtubules. Mitiotic spindle is formed during the polymerization process of the microtubules in centrosome. Any kind of disruption in the structure of the microtubules causes aberration in the spindle fibre structure and error in the number of chromosomes. This change is one of the major causes of developing cancer.
