Answer:
Plasmolysis occurs when a plant cell is inmersed in a 3X salt solution.
Explanation:
Plasmolysis is a phenomenon only observed in plant cells, and consists of cell dehydration accompanied by separation of the membrane and cell wall when the cell is exposed in a hypertonic environment.
When a plant cell is in a hypertonic solution —such as 3X salt solution— the permeability of its membrane allows water to escape, so the cell dehydrates and reduces its size. The cell wall is rigid and maintains its shape, but the cell membrane separates from it, which is known as plamolysis.
The other alternative answer combinations are not correct because:
Plamolysis does not occur in animal cells. Pure water does not produce plasmolysis.Right answer gets brainliest!!!!!!!!!!!!!

A scientist conducted a study of an organism and found that its body cells contained 40 chromosomes. While conducting her observations, the scientist noticed that the cells were undergoing cell division. What difference would the scientist expect to observe between the body cells and the sex cells of the organism as they underwent cell division?
Body cells divide by mitosis for the growth and repair of cells, while sex cells divide by meiosis for sexual reproduction.
Body cells divide by mitosis for sexual reproduction, while sex cells divide by meiosis for the growth and repair of cells.
Body cells divide by meiosis for the growth and repair of cells, while sex cells divide by mitosis for sexual reproduction.
Body cells divide by meiosis for sexual reproduction, while sex cells divide by mitosis for the growth and repair of cells.
Answer:
The difference that the scientist would expect to see between body cells and sex cells with respect to cell division is that body cells divide by mitosis for the growth and repair of cells, while sex cells divide by meiosis for sexual reproduction.
Explanation:
The behavior of the different cell types with respect to their division depends on the functions that each type has.
Somatic cells are those that define the structure and function of the organism, forming tissues by binding together. The process of mitotic division —to obtain from an original cell two identical daughter cells— is important for the growth, development and repair of an individual's tissues.Sex cells or gametes have half of the chromosomal charge —they divide by meiosis, a reductive cell division— and are involved in the process of sexual reproduction.The characteristics described for each cell type explain why the other options are not correct.
Answer:
Body cells divide by mitosis for the growth and repair of cells, while sex cells divide by meiosis for sexual reproduction.

Removing a specific group of trees within a small area over a long period of time is
a. clearcutting
b. seed tree cutting
C. group selection
d. single tree selection
Answer:
C. group
Explanation:
Removing a specific group of trees within a small area over a long period of time is group selection. The correct option is C.
What is group selection?A quantitative definition of group selection is when the average group fitness is greater or less than the mean of the fitness values of the individual members.
Another definition of group selection is when features evolve in accordance with the fitness (survival and reproductive success) of groups.
The conclusion was that although group selection is theoretically feasible, in practice it almost always favors one group over another.
Group selection is the long-term removal of a certain group of trees in a constrained region. In a clearcut, all the trees in a specific region are taken out at once.
The removal of shelterwood cutting clears an area's also clears land cleared for shelterwood cutting, which also involves cutting downing shelterwood cutting, but it is a completes a method of clearing
Thus, the correct option is C.

I WILL GIVE BRAINLIEST Pretend you're riding the bus to school on a very cold and snowy day. List 3 different phases changes you might see along the way.
While riding the bus to school on a very cold and snowy day three different phases changes you might see along the way are mentioned below:
1. precipitation(the snow falling)
2. evaporation(water turning into vapor)
3. melting(snow turning the water)
What is precipitation, evaporation, and melting?Evaporation is the process in which liquid changes in vapour or gas and it can be easily observed during hot summer days when there is raining and when wet clothes dry in the presence of sunlight. Evaporation is directly proportional to temperature and when rate of evaporation increases the temperature also increases.
Precipitation is the water that is falling from the sky and it occurs when a portion of atmosphere becomes saturated with water vapour.
Melting is the process in which solid is converted into liquid like ice cube converted into liquid water and this is one of the example of melting.
Therefore, the mentioned below are three phases changes :
1. precipitation(the snow falling)
2. evaporation(water turning into vapor)
3. melting(snow turning the water)

Mitosis is a type of cell division. Organize the images below to show the steps of mitosis.
Answer:
The correct order is:
#3 - will be first

#2 - will be fourth
Explanation:
The third image shows the cell in interphase or early prophase as chromosomes are present in the nucleus of the cell which is dense due to genetic material. The first image shows the metaphase the second stage of mitosis where chromosome are lined up at the metaphase plate and each sister chromatid is joined to a spindle fiber of the equator.
The fourth image given showing anaphase in which chromosome split into two each towards the opposite side of the plate. Due to spindle fiber cell initiates to elongate. The second image showing two daughter cells after cytokinesis which is the separation of cell into two different entities

I hope this helped and was explained better
The behavior type of response with the corresponding action is instinct-migration, trial and error-putting a puzzle together, conditional response-getting hungry before lunchtime, habit-brushing your hair, and reflex-eye blinking.
What is the corresponding action?The brain control action is regulated by the body some are involuntary and others are voluntary it creates a rhythm in our body to make the system regulate.
Migration is instinct but putting puzzle is a trial and error condition, when the eye is blinked is a reflex action, and crushing your hair is a habit while getting hungry before lunchtime is a conditional response.
All the action of the body is controlled by the body's action some signals are sent to the body to regulate every action to control conditional response or habit.
Therefore instinct-migration, trial and error-putting a puzzle together, conditional response-getting hungry before lunchtime, habit-brushing your hair, and reflex-eye blinking.
