Answer:
a solution of each sodium salt at the same concentration
Explanation:
If a scientist wishes to study the electrical potential that develops between ice and the sodium salts solution of the ions (F-, Cl-, Br-, or I-) in order to determine which ion produced the greatest electrical potential; he must compare the electrical potential that develops between ice and a solution of each sodium salt at the same concentration.
This means that conclusions can not be reached unless the sodium salt of each ion at the same concentration is compared so as to ensure consistence in the results of the study.

Explanation:
Earth's northern hemisphere generally experiences warmer temperatures in July than it does in January. Which statement explains why?
A. Sunlight shines more directly on the northern hemisphere in July.
B. Sunlight in the northern hemisphere is more spread out in July.
C. The interior of the Earth heats the northern hemisphere more in July
D. The northern hemisphere is tilted away from the Sun in July
Answer:
D
Explanation:
The northern hemisphere is tilted away from the Sun in July causing Earth's northern hemisphere commonly founds warmer temperatures in July than it does in January, hence option
Why are seasonal changes occur on Earth?When Earth is tilted over its axis, this causes seasons to occur on Earth during various months, this movement around the Sun is the major cause of seasons on Earth.
In July month, the northern half of Earth tilts toward the sun, temperature of the land increases, which heat up easier than the oceans. While in January, it's difficult for the sun to heat the oceans, observing cooler average global temperatures, although the Earth is closer to the sun.
Therefore, July experiences warmer temperatures because the northern hemisphere is tilted away from the Sun in July.

how does a plant cell look under a microoscope
Plant cell under the microscope
The structure and shape of the cell are more rigid when compared to animal cells as plant cells have a rigid cell wall that provides a more solid structure to the plant cell. The shape of the plant cell is usually rectangular in shape even though some plant cells have a triangular shape.i hope it helps you:-):-)
In humans, the "A" allele codes for Type A blood, the "B" allele codes for Type B blood, and the "o" allele codes for Type O blood. "A" and "B" are both dominant to "o." A and B are codominant to each other.
What is the genotypic ratio of a cross between a mother who is heterozygous Type A and a father who is heterozygous Type B?
A. 1 AB : 1 A0:1 Bo : 1oo
B. All AB
C. 2 AA: 2 BB
D. 1 Ao: 2 00:1 Bo
In a cross between two heterozygous tall and purple flowers (TtPp x TtPp), what would the
ratio be?
Answer:
9:3:3:1
Explanation:
This question involves two different genes coding for height and flower color respectively. The first gene posseses allele T (dominant) and t (recessive) while the second gene possesses allele P (dominant) and p (recessive).
According to this question, two heterozygous tall and purple flowers are crossed i.e. (TtPp x TtPp). Each parent will produce the following gametes combination:
TtPp - TP, Tp, tP, tp
Using these gametes in a punnet square, the following proportion of offsprings will be produced:
T_P_ (tall, purple) = 9
T_pp (tall, white) = 3
ttP_ (short, purple) = 3
ttpp (short, white) = 1
Hence, the ratio of this cross is 9:3:3:1

An object with a kinetic energy of 200 J and Potential energy of 300 J, has a mechanical energy of what?
Answer:
500 J
Explanation:
Emechanical=U+K,i.e., the mechanical energy Emechanical is the sum of the potential energy U and kinetic energy K.
So, the object has a mechanical energy of 200+300=500 J.

Tom described a certain phase in mitosis as follows: The centromere splits. The paired chromosomes separate and shift to the opposite sides of the cell, which stretches the cell. Which of the following phases will take place just after the phase described by Tom?
Anaphase
Metaphase
Prophase
Telophase
!!!PLEASE HELP!!!
Answer:
I'm not 100% sure, but I think its the Telophase.
Explanation:
The third phase of mitosis is called anaphase. This is when the separation starts. The centromere of each chromosome splits. The spindle fibers shorten and pull the sister chromatids apart until they are on opposite ends of the cell. Each chromatid is now a single, unreplicated chromosome. As a result of this, the cell stretches out. The phase after this is telophase.
Answer:
Ik I'm late but Telophase
