You have a cell, with a semi-permeable
membrane and a 1.5% potassium
concentration. You put it into a solution of
1.0% potassium. Is the solution hypertonic or
hypotonic? What direction would you expect
water to flow? What do you expect to see
happen to the cell?

Answers

Answer 1
The solution is hypotonic and therefore the water will flow into the cell and the cell will expand.

if blood calcium levels drop below 8.5 mg/dl which hormone is likely to be activated?

Answers

Answer:

Parathyroid Hormone (PTH)

Explanation:

The major function of the parathyroid glands is to maintain the body’s calcium level in both the blood and bones.

There is a narrow range of calcium required for the nervous and muscular systems to function properly. (A normal calcium level in the blood stream ranges from 8.5-10.2 mg/dL ).

When blood calcium levels drop below a certain level, receptors in the parathyroid gland release parathyroid hormone (PTH) in proportion to the amount of calcium that is required by the body. This hormone increases blood calcium levels by stimulating osteoclasts to release calcium by breaking down bone. Osteoclasts are cells in the bones that break down and remodel bone tissue.

I have used this site, if you would like to know more please read it whenever your free.

A student observes a reaction with an enzyme in a beaker. If nothing is removed from the beaker containing the reaction, what is the only thing the student must add to start the reaction again?


A.acids





B.enzymes

C.products



D.substrates

Answers

Answer:

90% Products, 10% Acids

Explanation:

enzymes are not consumed in a reaction. they remain mixed with reactants. if all products have reacted in the reaction and there's nothing left, the answer is products.

But acids promote chemical reactions at certain incidents. especially if it's an essential compound to the reaction.

Ex-: Sucrose is hydrolysed to Fructose and glucose by heating with an acid. but using sucrase, the same can be done.

Con đường vận chuyển nước vậy ông chất khoáng qua thành tế bào sang bào ở thực vật có đặc điểm gì

Answers

Answer:

In plants, minerals and water are transported through the xylem cells from the soil to the leaves. The xylem cells of the stem, roots, and leaves are interconnected forming a conducting channel reaching all plant parts. Thus, there is continuous water movement into the xylem.

Bài giải:

Ở thực vật, các chất khoáng và nước được vận chuyển qua các tế bào xylem từ đất đến lá. Các tế bào xylem của thân, rễ và lá liên kết với nhau tạo thành một kênh dẫn đến tất cả các bộ phận của cây. Do đó, có sự chuyển động liên tục của nước vào xylem.

Answers

Answer:

#4 Humans are more closely related to mice than they are to chickens or fish.

Explanation:

If you compare the human embryo with the mouse embryo, you can tell they look very similiar, like in the way they curl up and in their eye placement/size. With the other two- fish and chickens- they look extremely different in comparison to the human embryo. The comparisons that i used before (eye placement/size and formation) I'll use as an example. They look nothing similiar to each other, therefore the answer is #4.

during osmosis, the net movement of water molecules will be from areas of __ free energy to areas of __ free energy, or __ energetically.

Answers

Osmosis refers to the net movement (diffusion) of water molecules across a semipermeable membrane. This movement occurs in favor of a concentration gradient.

During osmosis, the net movement of water molecules will be from areas of HIGH free energy to areas of LOW free energy, or DOWNHILL energetically.

Osmosis involves the movement of water molecules in favor of a concentration gradient, i.e., from an area of high concentration to an area of low concentration.

Osmosis is a type of passive mechanism because it does not require energy to move water across the membrane.

When students get older, it gets even harder to wake up and it leads to many obstacles that can be avoided by starting school at later times. By starting schools later, students have been shown to improve academically, be more productive, not skip school, and maintain better health. A later start time should be incorporated into schools everywhere, especially high schools, for the benefit of teenage students. Grades are a very important aspect of education to many high school students, and grades are immensely dependent on adequate sleep. Later start times would allow for a greater quantity and quality of sleep. Poor sleep has a negative effect on a students academic performance. According to the Centers for Disease Control and Prevention (CDC), Adolescents who do not get enough sleep are more likely to perform poorly in school. Students who are not afforded the opportunity to get in the sufficient sleep they need will have a harder time focusing in school and doing well on exams. If schools were to push back the starting times in order to allow students to have a finer capacity of sleep, then the academic performance would improve, thus contributing to the common interest of all students. Many teenagers fall victim to car accidents and poor attendance records. Later start times would mean an improvement in attendance and safety as fewer students would sleep in or fall under the risk of driving to school in drowsy conditions. Enabling students to sleep more would cause more students to come to school on time and make them less likely to drive to school in a fatigued state. The Science Daily revealed that [...] later school start times were associated with a significant drop in vehicle accidents involving teen drivers. This could be tied to the fact that teens are in a more rushed mood to get to school on time from waking up late or that they are driving while tired, which can lead to many dangers. By starting schools at later times, the risks of teen car accidents would be reduced and the overall attendance would improve, thereby allowing for the betterment of students in all places Even with all the benefits of starting school at later times, there still remain those who challenge the idea. A common counterargument from the individuals in opposition to pushing back the schools starting times is that students should just sleep earlier. However, research has demonstrated that teenagers are biologically more likely to fall into a deeper sleep at later times. Science advocates say that young people's body clocks may shift as they reach their teenage years - meaning they want to get up later not because they are lazy but because they are biologically programmed to do. The biological clock of a teen does not correspond well with the schools starting times, and when a student is forced to wake up too early they are neglecting crucial parts of their sleep. In order to align better with teenagers internal clocks, schools should start at later times, which in return would result in the improvement of learning, concentration, and health. Students commit a large portion of their day towards school and it would be a more enjoyable process if schools were to start at a more seemly time. For the general welfare of students in public education, the school start times should be moved to later times. The benefits include better grades, fewer absences, safer roads, and increased attentiveness. There is additional potential to starting schools later, such as the reduction of risk in athletics, less depressive symptoms, and a decrease in the likelihood of participating in violence. The further possibilities can only be explored as more schools start pushing back their start times and in the idealistic future, schools will hopefully start to implement a delay to start times as it is better for everyone.
