7. Some plants make cones. Other plants make flowers. What is the purpose of flowers and cones?A. They move water and food throughout the plant.
B. They hold the plant and soil so that it does not blow over in heavy winds.
C. They make seeds so that the plant can reproduce.
D. They take in water and nutrients from the soil.
Answers
Answer:
I believe the answer is C.
Explanation:
Coniferous plants (= cone bearing) carry seeds in their cones. This leads me to believe the answer is C because cones do not move water, nutrients, or hold soil.

3. During which stage of the cell cycle would a cell contain the least total amount of DNA?
Scientist can determine the age of ancient objects by a method called radiocarbon dating. The bombardment of the upper atmosphere by cosmic rays converts nitrogen to a radioactive isotope of carbon, 14C, with a half-life of about 5730 years. Vegetation absorbs carbon dioxide through the atmosphere and animal life assimilates 14C through food chains. When a plant or animal dies, it stops replacing its carbon and the amount of 14C begins to decrease through radioactive decay. Therefore, the level of radioactivity must also decay exponentially. A parchment fragment was discovered that had about 64% as much 14C radioactivity as does plant material on Earth today. Estimate the age of the parchment.

Griffith, through his research was able to show that cells contain a transforming material, which was later termed DNA. DNA is the basis for inheritance in living organisms, thus he enhanced our understanding of how children inherit traits from their parents.
Answer:
The answer is by showing that cells contain a transforming factor.
Explanation:
Griffith, through his exploration could demonstrate that cells contain a changing material, which was later termed DNA. DNA is the reason for legacy in living life forms, accordingly he improved our comprehension of how kids acquire qualities from their folks.

b. keep all variables constant
c. change as many variables as possible
d. change only one variable at a time
Answers
Changing only one variable at a time is a rule for conducting a controlled
experiment.
Controlled experiment involves the use of dependent and independent
variables . Changes in the independent variable brings about a
corresponding change in the dependent variable which is then recorded.
It is however important to note that changing more than only onevariable at
a time won't accurately determine if the changes in the results were as a
result of one cause. This is why only one variable has to be changed at a
time.

B.) Solids have more energy than plasma
C.) Solids have the most amount of energy
D.) Solids have the least amount of energy
Answers
Answer:
The answer is D.) Solids have the least amount of energy
Explanation:
Because in a solid, particles are packed tightly together so they don't move much. The electrons of each atom are constantly in motion, so the atoms have a small vibration, but they are fixed in their position. Because of this, particles in a solid have very low kinetic energy.
Final answer:
Solids have the least amount of energy among the four physical states of matter because their particles are held tightly together and can only vibrate, possessing less thermal energy than in the liquid, gas, or plasma states.(Option D)
Explanation:
The correct statement about the energy level of solids is that solids have the least amount of energy among the four physical states of matter. In a solid, the atoms or molecules are held close together by strong intermolecular forces, which significantly restricts their ability to move. As a result, the particles can only vibrate about fixed positions, and this vibrational motion accounts for the thermal energy in solids.
This is less energy than the particles have in liquid, where they can move freely but are still close together, and much less than in gas, where the particles have enough energy to break away from one another and fill the available space. In plasma, which is an ionized state with even higher energy, particles have the most energy compared to the other states of matter.

I don't know exactly what you need but I give you an example so that you can create your samples through the Excel program, I hope it helps.
Just enter your sampling frame (the clients of which you have contact information) in the spreadsheet. Once you have a sampling frame (possible respondents) in Excel, you can easily select a random sample among them. For example, in your case that it is a work of biology and neceists three random samples here you can apply it with the following rules:
-Add a new column in the spreadsheet and name it "Random Number".
-In the first cell below your header row, type "= RAND ()".
-Press “Enter” and a random number will appear in the cell.
-Copy and paste the first cell in the other cells of the column.
-Once each row has a random number, organize the records from the "Random number" column.
-Then, select the first samples. In this way you will randomly choose from all samples.

This is because not all genes are expressed at the same time, so not all the proteins are present at a certain moment. The mechanisms that cell uses to control gene expression are called regulation of the gene expression. Thanks to regulation of the genes, cells have the ability to increase or decrease the production of specific gene products such as proteins. This property is important for the adaptability of an organism because it allows the cell to express protein when needed.
