Answers

Answer 1

Answer:

A. emigration or increase in death rate

Explanation:

i just took the test and got it rigt lol

Answer 2

The two possible reasons for the change within frog population is emigration or increase in the death rate. Thus, the correct option is A.

What factors affect the population?

The major factors which affect the population of a species are birth rate, death rate, and migration of the species.

Birth rate is the number of individuals born in a population in a particular time period. Birth rate adds more individuals to a population.

Death rate is the number of individuals die in a population in a particular time period. Death rate decreases the population number.

Immigration is the number of individuals which enter a population.

Emigration is the number of individuals which migrate out of a population.

Therefore, the correct option is A.

If the endoplasmic reticulars were removed from the cell, which organelle would not be able to function properly, and why?
1. Mitochondria, because they rely on the ER as an energy source
2.Ribosomes, because they receive proteins made by the ER
3.Golgi apparatus, because n packages proteins received from the ER
4.Cytoplasm, because it relies on the ER for structural support​

Answers

Answer:

3.Golgi apparatus, because n packages proteins received from the ER

Explanation:

1. Mitochondria, because they rely on the ER as an energy source  - this is false. The mitochondria are the energy-producing organelles in the cell. They do not rely on the ER for energy

2.Ribosomes, because they receive proteins made by the ER  - this is false, the ribosomes are the protein synthesis factories of the cell. Some of them are even attached to the ER

3.Golgi apparatus, because n packages proteins received from the ER  - this is true. The ER is involved in folding and modifying proteins, which are passed to the Golgi for further modification and transport.

4.Cytoplasm, because it relies on the ER for structural support​  - this is false, structural support is provided by the cytoskeleton

Brain cells, which depend on glucose for energy, use the glucose transporter GLUT3, which has a Km of 1.5mM. Liver cells, which store glucose (as glycogen) after a meal and release glucose between meals, use the glucose transporter GLUT2, which has a Km of 15mM. Calculate the rate (as a % of Vmax) of glucose uptake in brain cells and in liver cells at circulated glucose concentrations of 3mM (starvation), 5 mM (normal levels), and 7mM (after a carbohydrate-rich meal). Use this rearranged M-M equation.

Answers

Answer:

Explanation:

Given that:

The brain cell which uses glucose transporter GLUT3 Km = 1.5 mM

The liver cell which stores glucose GLUT2 Km = 15 mM

The objective is to calculate the rate (as % of Vmax) of glucose uptake in brain cells and liver cells under starvation conditions.

Using the M-M equation i.e Michaelis- Menten equation;

[tex]Rate = \dfrac{V_{max}* [S]}{[S]+K_m}[/tex]

By rearrangement

[tex]\dfrac{Rate}{V_{max}}= \dfrac{[S]}{[S]+K_m}[/tex]

where;

[tex]V_{max}[/tex] = maximum velocity of a reaction

Thus; the rate as a % of Vmax of glucose uptake in brain cells is calculated as:

[tex]\dfrac{Rate}{V_{max}}= \dfrac{[3 \ mM]}{[3 \ mM]+1.5 \ mM}[/tex]

[tex]\dfrac{Rate}{V_{max}}= \dfrac{3 \ mM}{4.5 \ mM}[/tex]

[tex]\dfrac{Rate}{V_{max}}=0.667[/tex]

[tex]\dfrac{Rate}{V_{max}}=66.7 \%[/tex]

the rate as a % of Vmax of glucose uptake in liver cells is calculated as:

[tex]\dfrac{Rate}{V_{max}}= \dfrac{[3 \ mM]}{[3 \ mM]+15 \ mM}[/tex]

[tex]\dfrac{Rate}{V_{max}}= \dfrac{3 \ mM}{18 \ mM}[/tex]

[tex]\dfrac{Rate}{V_{max}}=0.166[/tex]

[tex]\dfrac{Rate}{V_{max}}=17 \%[/tex]

Thus, the uptake is larger brain cells due to the fact that the brain cells GLUT3 have higher tendency to attract glucose.

Read the passage. PLEASE HELP ASAP I WILL GIVE BRAINLIST A Complication or TwoThe rejection letter from my Ivy League school of choice was the first major obstacle I encountered in my grand 10-year plan. It was not the last. I was 17, and at the time quite certain that nothing would derail me from my grandiose future. I planned to achieve everything my parents expected, and more. The first step was supposed to have been attending my parents alma mater, graduating with honors, and then moving on to law school without pausing to let my peersor competitorscatch me. To say thats not how it went is a gross understatement.Needing a distraction in my moment of crisis, I decided to pick up another couple of hours of volunteer service. I rode the subway to Tri-Valley Hospital with that rejection letter wrinkled in my right fist. I probably should have left it at home, but I couldnt bring myself to put it down. Id spent so many hours volunteering at Tri-Valley to build my community service rsum that the trek there felt like it was accomplished on autopilot rather than through any active involvement on my part.Alma was a new volunteer that morning, and I felt grateful for her presence, though I suppose I really didnt pay much attention to her. Mostly, I was relieved to have something to focus on, other than the big fat rejection letter swelling in my pocket. I showed Alma the volunteer wing, which was really just a room with a few lockers, a microwave, and a lot of large posters with rules and cautionary messages. She shadowed me on that shift, and together we delivered food trays, chatted with bedridden patients who didnt have visitors that morning, and carried out a number of fairly tedious tasks. I forgot Almas name three times and had to apologize. It was a unique enough name that I shouldnt have forgotten once, but the rejection letter was burning a hole in my pocket and apparently in my mind.At lunch, Alma sat across from me, even though by then several other regular volunteers had arrived and offered to take her out for real food rather than subjecting her to the cafeteria fare. I cant imagine how far gone I must have seemed to her, but Ill never forget what she said as I prodded the chocolate mass parading as cake on my tray. You must really love what you do here, she said. I can tell you care about this place and the patients we visited.Her words dug into me, primarily because I had never once stopped to consider whether I enjoyed my time at the hospital. Hundreds of food trays served, hundreds of patients visited, and still somehow the whole experience amounted to nothing more than a checkmark on the extensive list of what I needed to accomplish to achieve my goals. I did think about it then, as I finished my dessert. She wasnt incorrect. A lot of people hate hospitalsthe lights, the sterile smell, the undercurrent of urgency, illness, and tragedy. But I didnt hate it at all. The fact that I was there that day proved more than anything else that I saw it as a comfortable place.Alma and I ended up attending the same university. It wasnt Ivy League, and I wasnt pre-law. Freshman year, I decided to complete my undergraduate degree on an accelerated three-year plan. Although that three years stretched to four-and-a-half, when I graduated, my wife of two years, whose name I had not forgotten once since that first day at Tri-Valley, was by my side and expecting our first daughter. Medical school was its own unique challenge, especially after the twins came along halfway through. We purchased our first house the year they turned six, after I landed a residency at Tri-Valley. But we slept in a nearby hotel for the first two months of home ownership because of a burst pipe that flooded our bedrooms the week we moved in.Looking back, I suppose my life started with that letter. I dont think everything necessarily happens for a reasontheres too much tragedy in the world for that. But theres no doubt that some misfortunes turn into pivotal moments that can alter the course of a persons life for the better. Alma and I have been together for 30 years now, and I still wonder what that other lifethe one in which my letter said congratulationsmight look like. I expect it would have been pretty grand, full of its own triumphs and pitfalls. My children are fresh to the adult world, and when I see their tears as plans go sideways, I like to imagine that someday theyll sit where I am with people to love, hobbies to pursue, and maybe even a spare dollar in the bank.How does Alma influence the narrator's life?a. She has lunch with him instead of going out with the other volunteers.b. She is by his side throughout college.c. She points out how much he loves his volunteer work.d.
