Answer
:a. Cellular Respiration – what type of reaction? EXERGONIC .and how much energy 34 ATPs;Net gain of 32.
b. Why doesn’t sugar just explode on our countertops- sugar is a high energy-rich compound. Therefore high energy is needed to breakdown the bond-energy in it for phosphorylation to take place in glycolysis
c.<u> Photosynthesis – what type of reaction-</u>ENDOGONIC ….how much energy 18 ATPs used up and 12NADPHs
d.Where does the activation energy come from for photosynthesis SUNLIGHT
e. <u>Day to day, we use</u> ATPS <u> it is our energy coinage, we c</u>an STORE it and then cash it in.
f. What is the delta G value for breaking ATP down into ADP=−30.5 kJ/mol
Explanation:
Interphase:
-the cell replicates its chromosomes
-each chromosome has two sister chromatids held together by a centromere
Prophase 1 chromosomes coil up and a spindle forms
-homologous chromosomes come together matched gene by gene forming a tetrad
-Crossing Over may occur when chromatids exchange genetic material
-this occurs two or three times per pair of homologous chromosomes
-Crossing Over results in new combinations of alleles on a chromosomes
Metaphase 1:
-the centromere of each chromosome becomes attached to a spindle fiber
-the spindle fibers pull the tetrads to the equator of the spindle
-homologous chromosomes are lined up side by side as tetrads
Anaphase 1:
-homologous chromosomes separate and move to opposite ends of the cell
-centromeres do not split
-this ensures that each new cell will receive only one chromosome from each homologous
pair
Telophase 1:
-the spindle breaks down and the chromosomes uncoil
-the cytoplasm divides to yield two new cells
-each cell has half the genetic information of the original cell because it has only one homologous
chromosome from each pair
Prophase II-
-a spindle forms in each of the two new cells and the fibers attach to the chromosomes
Metaphase II-
-the chromosomes are pulled to the center of the cell and line up randomly at the equator
Anaphase II-
-the centromere of each chromosome splits the sister chromatids separate and move to opposite poles
Telophase II nuclei re form the spindles break down the cytoplasm divides identical to mitosis (Meiosis II)
What Meiosis produces four haploid sex cells from one original diploid cell each haploid cell contains one chromosome from each homologous pair haploid cells will become gametes transmitting genes to offspring
I hope this helps
1)How long did it take for the third of population to double?How long did it take for the population to double a third time? 2) 51 years
___________ A third time? It took 75 years for the population to double a second time and it took 51 years to double a third time. It will reach 8 billion at about 2024. 4.
Answer:
8
Explanation:
There are 3 sodium atoms, 1 phosphorus atom, & 4 oxygen atoms.
3+1+4=8 atoms in total
D. A variable or alteration to one part that affects an entire system
Explanation:
When talking about natural and physical systems, change is a variable or alteration to one part that affects an entire system.
Systems are groups of processes that have the same overall function. There are several types of interacting components that makes up both physical and natural systems in our world.
- The part of system is related and interconnected via the changes they undergo.
- Changes typically causes variation or alteration of parts of a system.
