Answer:
Explanation:
Place your arm on a desk or table top with your hand resting on the edge. Your thumb and forefinger need to be projecting over the edge and about 2cm apart.
Your LC, friend or family member will hold the meter stick in a vertical position so that the zero end of the meter stick is halfway between your thumb and forefinger. The holder of the stick will drop it without warning you. You are to catch the meter stick as soon as possible after it has been released. Record on the data table the number of centimeters the meter stick dropped before you caught it.
Repeat the procedure 9 more times.
Repeat the procedure in steps 2 and 3 but this time close your eyes and have your LC, friend or family member tell you the moment the meter stick is dropped. Repeat this 9 more times and record the data in the data table.
Repeat the procedure in steps 2 and 3 but this time use a tactile stimulus. Have your LC, friend or family member touch you as soon as the meter stick is dropped. Be sure your eyes are closed. Repeat 9 more times an

Explanation:
Suppose that somite stem cells commit to their cell fates by three days post fertilization. Which result would be MOST likely in the chick embryos receiving somites transplanted in the reverse order
The organs arising from quail somites develop in the reverse order because transcriptional programs activated in the nucleus can't be reversed.
What is a Nucleus?This is referred to as the part of the cell which is membrane bound and contains chromosomes.

how does one type of rock is transformed to another type of rock?
Answer:
This can happen through the rock cycle. But there are 3 processes which are crystalization, erosion and sedimentation, and metamorphism.
Explanation:
There are several types of rocks, but only one large furnace in which parts of a single large rock are cooked and changed into the various types of rocks. Our planet is a massive rock and a massive furnace. All rocks are divided into three categories, or classes. They're classified as sedimentary, metamorphic, or igneous, with variances in how they're generated.
I'll show you a schematic of the Rock Cycle instead of a detailed answer. It shows how one type of rock may be converted (metamorphic) into another under certain conditions. Just bear in mind that some types of rocks, such as sedimentary rocks, may form in a matter of hours, while others, such as metamorphic rocks, take millions of years to create.
Explain/identify each phase of the cell cycle. (interphase + mitosis + cytokinesis).
Answer:
Interphase is when cell grows, replacing it chromosomes while preparing for cell division.
Mitosis - copies its chromosomes and then segregates them, generating two identical nuclei.
Cytokinesis - the cytoplasm splits in half to make two new cells.

Gene regulation is more
specific in eukaryotic
organisms because . . .
A. in multicellular organisms cells differentiate.
B. there aren't as many chromosomes.
C. they are single-celled organisms.
D. their DNA is much smaller than in prokaryotic organisms.
Answer:
A.) In multicellular organisms, cells differentiate.
Explanation:
A.) is correct because eukaryotes are multicellular organisms. Not all of these cells are located in the same place or serve the same function. Because of this, many cells need to differentiate. When organisms have more specialized cells, they need to have more complex gene regulation processes in order to create these cells and control their behavior.
B.) is incorrect because eukaryotes have more chromosomes than prokaryotes. While prokaryotes only have one circular chromosome, eukaryotes can have many more depending on the species.
C.) is incorrect eukaryotes are not single-celled organisms. Eukaryotes are multicellular organisms and prokaryotes are single-celled organisms.
D.) is incorrect because eukaryotes have a lot more DNA than prokaryotes. This makes sense because eukaryotes are more complex than prokaryotes.

Geoffrey records the heat transfer occurring in a sample of matter as being about one half as fast as he originally predicted. He concludes that the atomic structure of this matter must be more rigid and solid, as more rigid atomic structures make the particles move less, thus decreasing the ability for it transfer heat.
Geoffrey's idea is wrong because heat transfer is fastest in solids.
What is heat transfer?Heat transfer is the process by which energy is transferred from one point to another.
During the process of heat transfer, heat energy flows from hot to colder bodies.
The three processes of heat transfer are conduction, convection, and radiation.
Heat transfer is fastest in solids and slowest in gases.
Therefore, based on the nature of heat transfer, Geoffrey's idea is wrong because heat transfer is fastest in solids.

why might stem cells from human embryos be more useful than stem cells
from adults?
Answer:
Embryonic stem cells are more useful than the adults stem cells because;
* Embryonic stem cells have the ability to create any cell type in the human body while, the adults stem cells are more specialized( they generally make cells only from their tissue of origin).
They have the capacity to divide into additional stem cells or any kind of body cell.
What is the importance of stem cells of embryo?Embryonic stem cells can develop into any type of human cell, whereas adult stem cells are more specialized and typically can only produce cells from the tissue from which they originated.
Additionally, it is simple to produce embryonic stem cells in a lab setting. There is always the option to manufacture more cells as needed because the cells can be developed through cultures.
Since embryonic stem cells are pluripotent, they are more adaptable in scientific experiments than adult stem cells. Finding novel treatments for ailments, wounds, and organ failure is one of the possible advantages of studying embryos.
Therefore, Embryonic stem cells are more useful than the adults stem cells.
