What does a cell have to do to move a substance from an area of low concentration to an area with high concentration
Answers
Answer:
The cell has to undergo a process called Osmosis
Cell performs diffusion and osmosis to move substances from an area of low concentration to an area with high concentration through the semi-permeable membrane.
What is Cell transport?
Cellular transport is the mechanism through which substances move from a region of low concentration to a region of high concentration. Cellular transport takes place through osmosis and diffusion.
In osmosis and diffusion, the particles such as water and ions move due to concentration gradient from a region of high concentration to the region of low concentration of particles through the cell membrane. The membrane allows the movement of non-polar substances through membrane however some particles are unable to cross the membrane and thus requires transport proteins which facilitates their movement.

There are two forms of diabetes. Type II diabetes is also known as late-onset diabetes because it typically affects adults. Consider the following information about Type II diabetes:
Studies have shown that the lifetime risk for developing Type II diabetes is 40% for individuals who have one parent with Type II diabetes.
If a person has two parents with Type II diabetes their risk rises to 70%
Other factors that affect your risk for Type II diabetes include obesity, a sedentary lifestyle (not moving around much), a small or large birth weight, and stress.
Use the information above to answer the question: Is your risk of having Type II diabetes due to your genes, or due to the influence of the environment on your genes (epigenetics), or both?
Answers
Answer:
Both
Explanation:
As explained in the passage wether your mom or dad or both have had type ll diabetes in the past determines your risk of having it as well which is part of your genes. But also the influence of the environment on your gene is also a cause to type ll diabetes . Some people would rather stay inside rather than get exercise or some people would rather eat candy or sweets for breakfast or dinner all these things are causes of type ll diabetes which they are caused by the influence big the environment on your genes.

Answers
Answer:
The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell

Which best describes the alternation of generations? Fertilization produces haploid spores. Meiosis produces a diploid zygote. A gametophyte is its diploid phase. A gametophyte is its haploid phase.
Answers
Answer:
A gametophyte is its haploid phase.
Explanation:
The statement that best-described alternation of generation would that a gametophyte is a haploid phase.
Alternation of generation is a type of life cycle that involves alternating between the diploid (2n) and the haploid phase of the same organism. The haploid gametophyte produces the male and female gametes that fuse together to form a diploid zygote during fertilization.
The zygote divides mitotically to give the diploid sporophyte. The latter undergo meiosis to produce haploid spores which then germinates to give rise to haploid gametophytes and the cycle is repeated.
Answer:
D. A gametophyte is its haploid phase.

A scientist is extracting the DNA of a multicellular organism. He finds that 20% of the strands bases are Thymine. Based on Chargaff's rule, what percentage of the
strands bases would be Adenine?
A. 20%
B. 70%
C. 40%
D. 60%
Answers
Answer:
A. 20%
Explanation:
A DNA molecule consists of four nucleotides viz: Adenine (A), Thymine (T), Guanine (G), and Cytosine (C). According to Chargaff in his complementary base pairing rule, these nucleotides pair with one another in such a way that A bonds to T, while G bonds to C.
Based on Chargaff's rule, the amount of Adenine in the DNA is equal to the amount of Thymine while the amount of Guanine is equal to that of Cytosine i.e. A=T, G=C.
A + T + G + C = 100%
Hence, in this question, a scientist finds that 20% of the strands bases are Thymine. This means that the amount of Thymine in that DNA will also be 20%. S
Since A=T = 20% in accordance to Chargaff rule.

Erythrocytes (red blood cells)have no nucleus, mitochondria, orother organelles at maturity. Theseorganelles are ejected when the RBCenters the bloodstream, or shortlythereafter. Should this still beconsidered a cell? What will be theeffect of having no nucleus? In thesecells, the lack of mitochondria is anadvantage. Why?
Answers
Answer:
Erythrocytes are not considered true cells, because of their lack of a nucleus. The effect of having no nucleus makes their self-reproduction impossible, and the absence of mitochondria is a disadvantage because they have to obtain energy by alternative reactions.
Explanation:
Erythrocytes, or red blood cells, are the structure in charge of transporting gases in the blood. When these cells are mature, they have already lost their nucleus —in order to have space to house the hemoglobin molecule— which prevents mature red blood cells from being able to reproduce.
Additionally, red blood cells do not have mitochondria —the main energy generator in eukaryotic cells— so in order to obtain energy they need to perform lactic fermentation, with a lower enegetic yield, which may be a disadvantage, but sufficient for this structure to perform its function.
