Answer:

Cells are so little, so they can maximize their ratio of surface area to volume.

Explanation:

Smaller cells have a higher ratio which allows more molecules and ions to move across the cell membrane per unit of cytoplasmic volume. Cells are so small because they need to be able to get the nutrients in and the waste out quickly.

Warmer oceans would mean less dissolved CO2 as well as other gases such as oxygen in the global ocean. Lower CO2 would result in a decrease in photosynthesis of autotrophs living in the oceans.

Answer:

The correct answer is - 6.8950.61 gm per mole

Explanation:

Given:

One form of hemoglobin is 0.324% Fe by mass

1 hemoglobin = 4 Fe

Solution:

Molar Mass of iron = 55.85

mass of 4 iron atom = 55.85 * 4 = 223.4 gms

0.324 % correspond to 223.4 gms

100 % correspond to = 223.4 *100/0.324

= 68950.61 gm

MM of haemoglobin = 68950.61 gms = 6.8 E4 gms

In order for this code to represent a piece of DNA, which base must be replaced by thymine?

HACTEHA [7]

I guess you forgot to add the picture or so.
Based on the Complementarity of the 4 nucleotides, The thymine must always be placed in front of the Adenine, and the Cytosine must always be placed in front of the Guanine.
Any change in this rule causes the deformation of the DNA, and can sometimes cause fatal diseases like the melanoma (skin cancer) etc...

Hope this Helps! :)
