Describe the difference between a chemical and an electrical gradient. What's an electrochemical gradient? Do you think an electrochemical gradient can have conflicting component gradients?
Answer:
1) The difference between chemical gradient and electrical gradient is that chemical gradient refers to the change in concentration of an ion or molecule in a solution across a biological membrane while electrical gradient refers to the existence of an electrical potential difference that leads to the movement of charged ions towards or away from the electrical potential
2) Electrochemical gradient is the charge and ion concentration difference across a biological membrane
3) No because electrochemical gradient which consists of both an electrical and chemical gradient have a complementary effect in determining the level of the electrochemical gradient.
Explanation:
The electrochemical gradient is the gradient of the electrochemical potential and is usual for a positive and negative ion that can move across the membrane.
What is the electric gradient ?The gradient is made of two parts that are chemical which is different in solutes that can move across the membrane and have an electrical component that shows difference in changes across the membrane.
The electrostatic gradient is a potential used in an iron that can be used across the membrane. Due to unequal concertation of ions, they will move across the simple diffusion.
The electrochemical has potential in electroanalytical industries as batteries and fuels. The gradient has contrasting components as change across the membrane.

Explanation:
Answer:
50 percent
Explanation:
The composition of soils varies from place to place. But in good-quality surface soil, mineral and organic matter make up about half the volume. The other half is made of pore spaces that are filled with air and water.
The Black Death was a pandemic spreading across Europe between 1348 and 1350. Estimates states that 30% to 60% of Europe's population died from the Black Death. If we look at Europe's population before the pandemic and compare it to the population several generations later, what are we likely to find?
A. More genetic diversity in later generations.
B. Less genetic diversity in later generations.
C. Less genetic diversity in earlier generations.
D. The same degree of genetic diversity in later as in earlier generations.
Answer:
The correct answer is option B, that is, less genetic diversity in later generations.
Explanation:
A pandemic that spread across Europe between 1348 and 1350 was named as the Black Death. It has been predicted that of the total population of Europe at that time 30 to 60 percent died due to the pandemic. The geneticists are still trying to document the influence of Black Death on the population of Europe today.
It has been found that in England, the genetic diversity is found much lower in comparison to what it was in the eleventh century, and is primarily due to so many people dying in the 1300s. However, the rest of Europe does not demonstrate a dropped amount of genetic variation, which maybe because of the enhanced patterns of migration in other places.
In order for translation to occur: Please choose the correct answer from the following choices, and then select the submit answer button. transcription must be occurring simultaneously. there must be large numbers of free amino acids present in the cytoplasm. the DNA must produce large numbers of free amino acids. replication must be occurring simultaneously. the nuclear membrane must first dissolve
Answer:
there must be large numbers of free amino acids present in the cytoplasm
Explanation:
In order for translation to occur, there must be a large number of free amino acids in the cytoplasm.
These free amino acids are usually carried by the transfer RNA which also carries the corresponding mRNA codon.
During translation, as the codons in the mRNA match their complements in the tRNA, the amino acid being carried by the tRNA is released and a peptide bond is formed between subsequent amino acids until the required polypeptide bond is formed.
Translation and transcription only occur simultaneously in prokaryotic cells where there is no barrier between the cell's genetic materials and the cytoplasm, unlike in eukaryotic cells where the genetic materials are housed in the membrane-bound nucleus.

The table below summarizes Mendel’s results for the F2 generation. Mendel’s Results Plant height 787 tall 277 short Flower color 705 purple 224 white Flower position 651 middle of stem 207 end of stem Pod color 428 green 152 yellow Pod shape 882 inflated 299 constricted Seed color 6,022 yellow x green Seed shape 5,474 smooth 1,850 wrinkled What number should replace the letter x in the “Seed color” row? 152 207 224 2,001
Answer:
2001
Explanation:
This question showcases a table that displays Mendel's results (figures) when he crossed pea plants and observed different characters in the plant. Mendel worked with different phenotypic characteristics in the pea plant.
According to the table, the result were for seven characteristics including height, flower color, flower position, pod color, pod shape, seed color, seed shape. Based on the observation of the number of F2 offsprings that possessed dominant trait and recessive trait for each character, we will notice that it follows an approximate phenotypic ratio of 3:1
1. Plant height 787 tall 277 short (3:1)
2. Flower color 705 purple 224 white (3:1)
3. Flower position 651 middle of stem 207 end of stem (3:1)
4. Pod color 428 green 152 yellow (3:1)
5. Pod shape 882 inflated 299 constricted (3:1)
6. Seed color 6,022 yellow X green
7. Seed shape 5,474 smooth 1,850 wrinkled (3:1)
This 3 dominant : 1 recessive ratio is the ratio got in the F2 offsprings when he observed the seven characteristics in pea plants. Hence, the seed color will also follow the same 3:1 ratio
Therefore, 2001 is the result Mendel obtained in the F2 offsprings for the recessive trait of seed color characteristics in his experiment, which actually depicts the 3:1 ratio. Hence, X (green seed color) is 2001
I believe that the answer is C. 2001

Which best contrasts self-renewal and differentiation?
Answer:
Self-renewal is a kind of cell division specific to stem cells, so cell division is a general term. When self-renewal occurs, a stem cell divides into two cells, one of which is still a stem cell (which can display differentiation potential into one or more types of differentiated cells (stemness/potency) and divides almost indefinitely = self-renewal), and another is a differentiated cell, which may or may not divide, but its divisions (if any) are not self-renewal because (1) no stem cell (i.e. a cell with developmental potential) is produced, and (2) these divisions are finite (so they are not self-renewal, because self-renewal is indefinite yet controlled proliferation). In sum, self-renewal is a stem cell's 'unlimited' division while retaining its developmental potential.
Of note, stem cell immortality is thanks to the expression of the enzyme telomerase.

A woman consumes 500 grams of carbohydrate, 30 grams of protein, and 75 grams of fat in one day. How many total kcalories has she taken in, and how many and what percentage of kcalories are from carbohydrate, protein, and fat?
A. Total kcalories:
B. Percentage of kcalories from carbohydrate:
C. Percentage of kcalories from protein:
D. Percentage of kcalories from fat:
Answer and Explanation:
The computation is shown below:
A. For Total k. calories
= (Number of grams in carbohydrates × 1 gm of carbohydrates) + (Number of grams in protein × 1 gm of proteins) + (number of grams in fat × 1 gm in fat)
= (500 × 4) + (30 × 4) + (75 × 9)
= 2000 + 120 + 675
= 2795 k. calories
b. As we know that
1 gm of carbohydrates = 4 k. calories
So, for 500 grams it would be
= 500 × 4
= 2000 k. calories
Now the percentage is
= Total grams in carbohydrates ÷ Total kcalories
= 2000 ÷ 2795
= 0.72
= 72%
C. As we know that
1 gm of proteins = 4 k. calories
So, for 40 grams, it would be
30 × 4 = 120 k. calories
Now the percentage is
= Total grams in protein ÷ Total kcalories
= 120 ÷ 2795
= 0.043
= 4.3%
D. As we know that
1 gm of fat = 9 k. calories
So for 75 grams, it would be
75 × 4 = 200 k. calories
So, the percentage is
= Total grams in fat ÷ Total kcalories
= 200 ÷ 2795
= 0.072
= 7.2%
