I am wondering how to find out the blood type of my grandson...my daughter is A+..father is in question...she is stressed to the max on the father of this baby boy.
Answer:
A person can identify their blood type at home using a rapid blood typing kit. Using the kit requires a person to pierce a finger with a needle. The kit comes with a card that contains chemicals known as reagents. These test for the presence of the antibodies and Rh factor.
Explanation:
Just like eye or hair color, our blood type is inherited from our parents. Each biological parent donates one of two ABO genes to their child. The A and B genes are dominant and the O gene is recessive. For example, if an O gene is paired with an A gene, the blood type will be A.

List and Describe the two groups of clastic sedimentary rock.
Answer:
Clastic sedimentary rocks are formed from rock fragments or clasts; chemical sedimentary rocks precipitate from fluids, and biochemical sedimentary rocks form as precipitation from living organisms.
Sedimentary rock is classified into two groups based on how they form. They are clastic and chemical. Clastic sedimentary rock is formed as bits of weathered rock become cemented together. Because all kinds of rock are subject to weathering many different minerals can make up this group of rocks.

Animal Cell Cytokinesis
Explanation:
Answer: Animal cell
Explanation:) It refers to the process of cell division, which takes place during mitosis, is known as cytokinesis.
The process of cytokinesis is different for animal cell and plant cell.
Where, in case of plant cell, a separation, known as cell plate is formed along the center of the parent cell, which is responsible for the separation of the cells.
Whereas, in case of animal cell, the plasma membrane contracts itself along the center, until the two daughter cells are separated from each other.
Hence, from the given information of the question,
The correct answer is animal cell.

Step 1: Gather materials and necessary information.
a) You will choose an energy transformation to show. Some of the ones you have learned about
include those that occur in a burning bonfire and a wind turbine.
• Do research to find out about an energy transformation that affects your daily life.
• Find out what the starting types of energy are and what the ending types of energy are.
• Decide how many steps in the process your poster will show.
• Create bar graphs or pie charts to show the relationship between the different types of
energy at different steps in the transformation process.
b) Be sure to keep a list of your references so you can cite them later.
Step 2: Decide on a title.
a) Begin by deciding on a title for your poster and writing it neatly at the top.
b) The title should identify the energy transformation you are showing.
Step 3: Create your graphs.
a) Decide how many graphs you will need to show the energy transformation.
b) You should have at least 3 graphs so that the steps of the transformation will be clear.
c) Each graph should be clearly labeled.
d) Careful use of color on your graphs will make them easy to read and understand.
Step 4: Decide on the descriptive words to include on your poster.
a) People looking at your poster may need more information than just the title and the
graphs. Decide on how you want to present the information your viewers need.

Explanation:
At what temperature would a 1.30 m NaCl solution freeze, given that the van't Hoff factor for NaCl is 1.9? Kf for water is 1.86 ∘C/m .
Answer:
-4.59°C
Explanation:
Let's see the formula for freezing point depression.
ΔT = Kf . m . i
ΔT = Freezing T° of pure solvent - Freezing T° of solution
Kf = Freezing constant. For water if 1.86°C/m
m = molality (moles of solute in 1kg of solvent)
i = Van't Hoff factor.
0°C - Freezing T° of solution = 1.86°C /m . 1.30m . 1.9
Freezing T° of solution = - (1.86°C /m . 1.30m . 1.9)
Freezing T° of solution = - (1.86°C/m . 1.30m . 1.9) → -4.59°C
NaCl → Na⁺ + Cl⁻

Explanation:
Water was on earth with the dinosaurs and almost at the very start.
Water starts anywhere from clouds to ponds
I choose ponds, water evaporates from the sun and moves its way through the air being collected into clouds in the atmosphere, clouds are evaporated water molecules, then the water combines to form rain wich then end up on a hill and travel back to a water source or goes into the ground and makes groundwater and if there is enough rain overtime will form a pond.
