Answer:
1.) It is controversial because in order to take embryonic stem cells, the embryo must die. This is killing a baby.
2.) Stem cells can be taken from your own body from your blood stem cells. This kind of transplant would be considered an autologous stem cell transplant and could help heal diseased or damaged bone tissue.
Hope this helps!
PLEASE HELP!!!!!!!!!!!!!!!!!!!! WHAT IS THE CONTROL GROUP FOR THIS
Hypothesis:
In this section, please include the if/then statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.
If predators are increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.
If pollution is increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.
If the amount of food available is increased, then the cricket frog population will (increase/decrease/stay the same) over the span of five years.
Procedure:
The procedures are listed in your virtual lab. You do not need to repeat them here. Please be sure to identify the test variable (independent variable), outcome variable (dependent variable), and control group for this experiment.
Reminder: The test variable is the item that is changing in this investigation. The outcome variable is the item that you are measuring in this investigation. The control group is the group in the experiment where the factors being tested are not applied. It allows scientists to set a baseline to compare the experimental groups that do have factors applied to them.
Test variable (independent variable): Limiting factor- Food, Pollution, Predators.
Outcome variable (dependent variable): Cricket Frog (population)
Control group:
Answer:
decrease
decrease
increase
control group is the cricket frog population
Explanation:
Its the group that is being measured.
Answer:
Limiting factor- Food, Pollution, Predators.
Outcome variable (dependent variable): Cricket Frog (population)
Control group: Cricket Frogs in the Florida Everglades without changes in or manipulation of the population.

Which of the following is NOT a form of active transport? A) cyclosis B) phagocytosis C) diffusion D) pinocytosis
Diffusion is not active and instead a form of passive transport. So the correct option is option C.
Because diffusion is a non-electrical process, small particles move faster than larger ones. For example, molecules such as oxygen, CO2, and glucose move through cells.
Active transport involves moving molecules from a low-concentration region to a high-concentration region. In contrast to diffusion, active transport involves moving molecules against a concentration gradient.
The term “active” refers to the fact that transport is energy-dependent. Active transport is energy-intensive, whereas diffusion is energy-free.

What are some processes that take CO2 out of the atmosphere.
Photosynthesis photosynthesis takes carbon from the atmosphere but do not get it mixed up with respiration which takes O2 out the atmosphere and replaces it with Co2
Photosynthesis takes carbon from the atmosphere but do not get it mixed up with respiration which takes O2 out the atmosphere and replaces it with Co2.
What do you mean by photosynthesis?Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
The energy from light causes a chemical reaction that breaks down the molecules of carbon dioxide and water and reorganizes them to make the sugar (glucose) and oxygen gas. After the sugar is produced, it is then broken down by the mitochondria into energy.
Photosynthesis requires sunlight, carbon dioxide, and water as starting reactants. After the process is complete, photosynthesis releases oxygen and produces carbohydrate molecules, most commonly glucose.

A plant is an example of a heterotroph. True
False
Answer:
False
Explanation:
Heterotroph means energy is made through consuming another organism.
Autotroph means energy that is made through producing by itself.
A plant makes energy by itself
So a plant is an autotroph, so this statement is false.

Subsequent studies demonstrated that there is strong selective pressure maintaining Mc1r allele and coat colour frequencies across the short geographic distances between the light- and dark-coloured rock islands. Thus melanism in rock pocket mice is considered a fabulous example of adaptation by natural selection.

what is one reason cell biology is important? explain
Cell biology helps in understanding the state of cell, its functioning, which further helps in understanding the living things more clearly.
Cell biology• A branch of biology, which examines and studies the function, structure, and behavior of cells.
• All living things are formed of cells, and a cell is the fundamental unit of life, which is accountable for living and working of organisms.
• Cell biology is important as by knowing how the cell functions in both diseased and healthy conditions, the cell biologists can work with plant, animal and medical science and will be able to create novel vaccines, plants with better qualities, and more efficient medicines.
Thus, cell biology is a branch that deals with the study of cells, which can further help in better understanding of the living things around us.

Line CD is the perpendicular bisector of segment AB. The lines intersect
at point E. Which of these statements is true?
(Hint: it may help to draw a picture, but you don't have to turn it in!)
There is not enough information to be sure.
O E is closer to A than to B.
O E is closer to B than to A.
O E is the same distance from A and B.
plz help me understand this
Answer:
Option - E is the same distance from A and B.
Explanation:
Perpendicular bisector can be understood by this explanation:
If line n is intersected by line n at the center of line n
, then line m is the perpendicular bisector of line n
There are 4 right angles formed due to this perpendicular bisector around this mid-point
∵ Line CD ⊥ of segment AB
∴ Line CD intersects segment AB at the middle point of AB
∵ Line CD and segment AB intersected at point E
so, E ∈ AB and E ∈ CD
⇒ Point E is the mid-point of line AB
⇒ E is the same distance from A and B.
Thus, the correct option is - E is the same distance from A and B.

Where and how do hurricanes form?
Explanation:
Hurricanes form over the warm ocean water of the tropics. When warm moist air over the water rises, it is replaced by cooler air. The cooler air will then warm and start to rise. This cycle causes huge storm clouds to form.
Hurricanes can be defined as a serious type of storm which forms over
tropical or subtropical waters.
Hurricanes typically forms in the warm ocean water of the tropical or
subtropical regions
Hurricane involves the warm moist air over the water rising due to
evaporation which is then replaced by cooler air. The cooler air then warms
up and start to rise and then the cycle continues. This continuous cycle
makes huge storm clouds to form.
