mosses are dependent on external water for sexual reproduction because:
Answer:
sperm must swim through water to reach and fertilize eggs
True or false compared with the other substances water requires a lot of heat to increase its temperature
True. Water has a high specific heat capacity (4.18J/g/K) compared to other substances, thus more heat is required to raise its temperature. This can be explained by water's strong hydrogen bonds.

Human blood consists of blood groups A, B, and O. However, there is one more blood group, AB, which contains alleles A and B in the same genotype. What is this phenomenon called?
A.
coinheritance
B.
codominance
C.
incomplete dominance
D.
polygenic inheritance
Answer:
Coinheritance
Explanation:
It is coinheritance because, if the placement of the A and B molecules on each cell is controlled by the proteins that are coded by different versions of the same gene, then IA and IB are codominant but both are dominant to Io. If a person receives an IA allele and a IB allele, their blood type is type AB, in which characteristics of both A and B antigens are expressed.
Answer:
B: codominance

Place the rock layers in order from oldest to youngest with the oldest layer on the bottom and the newest layer on top. Remember that extinction is forever. Once an organism disappears from a layer, it will not reappear in a newer layer. Take a screenshot of your results to include in your Lab Report.
The organization of the rock layers from bottom to top is 3, 4, 8, 5, 6, 2, 1, and 7.
As shown in the image there are different layers of rock disorganized, each containing several specific species of organisms.
To organize them, it was necessary to analyze the organisms that were becoming extinct and what arose in each layer. According to this analysis, the layers were organized in the following order from oldest to newest:
Layer 3 (organisms 1, 2, and 3)
Layer 4 (organisms 1, 2, 3, 4, and 5)
Layer 8 (organisms 1, 2, 3, and 4)
Layer 5 (organisms 1, 2, 3, 4, 6, and 7)
Layer 6 (organisms 6 and 7)
Layer 2 (organisms 6, 7, and 8)
Layer 1 (organisms 6, 7, 8, and 9)
Layer 7 (organisms 7, 8, and 9)

The solute potential of a plant cell is -10 bar, and its pressure potential is 3. The plant cell is placed into a solution with a water potential of -10 bar.
What is the water potential of the cell, and in which way will water move?
The water potential of the cell would be -7 bar and thus, water will move from the cell to the surrounding solution.
Recall that:
Water potential = pressure potential + solute potential
For the plant cell, solute potential = -10, pressure potential = 3
Water potential of the cell = 3-10
= -7 bar
The water potential of the cell is -7 bar while that of the surrounding solution is -10 bar. Thus, the cell has a higher water potential than the surrounding solution.
Recall that water usually moves from the region of high to the region of low water potential. Therefore, water will move from the cell to the surrounding solution.

5. Juan’s cell phone company charges $35 a month for the phone service plus $0.50 for each text message. How many text messages does Juan send in a month if his bill was $52? plz help its due today
Answer:
Juan sent 34 text messages in a month
Explanation:
You have to create an equation for your problem!
t = text messages
The equation below represents the charge for Juan's cell phone usage
35 + 0.50t =$
Substitute 52 for "$" since that is the amount of the bill sent to Juan for a particular month.
Solve!
35 + 0.50t = 52 ---- subtract 35 on both sides
0.50t = 17 ----divide 0.50 on both sides
t =34

All of the following will help the skin to fight infection but one. Which of the following will have little effect on the skin's ability to fight infection? Group of answer choices More tight junctions between keratinocytes of the stratum corneum. Greater production of melanin. Increased secretions of defensins from skin cells. Greater production of keratinocytes resulting in more layers of the stratum corneum.
In order for the skin to fight off infection more efficiently and of the options listed, the correct choice would be for the skin to secrete more defensins.
Keratinocytes are the cells that constitute the epidermis. They are the most dominant cell type in this region and function to create and maintain this barrier. Though this barrier that they create does in fact aid in avoiding bacterial infection, it does little to fight off an already existing infection.
The correct answer is for the skin cells to secrete a greater number of defensins. These are small cationic proteins which are known as "Host Defense Peptides". What this means is that these defensins will either have direct anti-infection properties, or they will act as signals for the immune system.

The fossils that scientists find and study today formed thousands to millions of years ago. But, you can simulate the process of fossilization. Follow these steps to model a fossil:
Line the inside of the plastic container with plastic wrap.
Let the ends of the plastic wrap hang out of the container. The overhanging ends will allow you to more easily lift out your formation when it’s complete.
Pour four inches of water into the container. Use a ruler to measure the correct depth.
After adding the water, add two inches of sand.
Spread the twigs and leaves in a thin layer on the top of the sand.
Stay safe! Use gloves when handling the leaves and when checking the inside of your model during the weeks to come. Wash your hands and gloves when you are done.
Part A
After assembling the materials, record your observations. Describe what the setup looks like and the color of the leaves and twigs. Predict what changes will take place over the next few weeks.
