What happens to a spermatid to change it into a sperm cell? meiosis occurs, making the sperm cell haploid. the nuclei of two polar bodies fuse, making a diploid cell. a tail is added, making the sperm a motile cell. a membrane hardens, making the sperm a nonmotile cell.
A spermatid changes it into a sperm cell is that meiosis occurs, making the sperm cell haploid.
What is spermatogenesis?Spermatogenesis is the procedure of sperm cell development. Rounded immature sperm cells experience successive mitotic and meiotic divisions (spermatocytogenesis) and a metamorphic change (spermiogenesis) to produce spermatozoa.
Thus, a spermatid changes it into a sperm cell is and meiosis occurs, making the sperm cell haploid.

7. Which type of character provides useful data for cladistic analysis?
Answer: the basis of the cladistic analysis is data on the characters, or traits, of the organisms in which we are interested. these characters could be anatomical and physiologicl characteristics, behaviors, or genetic sequences.
Explanation:
1. Identify the following elements of hypothesis-based science in this example: (a) question, (b) hypothesis, (c) prediction, (d) control group, and (e) experimental group. (For additional information about hypothesis-based science, see Chapter 1 and the Scientific Skills Review in Appendix F.) 2. Explain how the types of data the researchers chose to collect enabled them to test their prediction. 3. What conclusion do you draw from the data presented above? 4. (a) Predict what would happen if, after 22 months, guppies from the transplanted population were returned to the source pool. (b) Describe an experiment to test your prediction.
Based in the experiment with the guppies, it can be concluded that natural selection is a factor of evolution.
What is a hypothesis?A hypothesis is an explanation put forward to explain an observation without prior testing.
From the observations in the guppies;
The question is whether natural selection is favors coloration in guppiesThe hypothesis is that natural selection determines coloration in guppies The prediction is that guppies with bright coloration will thrive in a predator free environment The control group is the source poolthe experimental group is the transfer poolthe conclusion from the data is that guppies with bright coloration are naturally selectedReturning the guppies from the transfer pool to the source pool will essentially reduce the population of the bright colored guppies due to predation.Therefore, it can be seen from the guppies that natural selection drives evolution of species.

What is the role of sunlight in biosphere?Photosynthesis is a process that organisms like plants, algae, and cyanobacteria used to turn carbon dioxide and water into organic molecules like carbohydrates.
The primary source of organic matter in the biosphere is this mechanism.
The sun powers the biosphere. This is so because the biosphere depends on the sun for its source of energy.
The compounds known as photosynthetic pigments catch the solar energy that powers the biosphere and use it to create organic molecules out of carbon dioxide and water.
Therefore, Biosphere regarding carbon be most immediately affected by a decrease in sunlight.

11.) If a hypotonic solution surrounds a cell; water will ___.
a.) stay the same
b.) be transported by proteins in the plasma membrane
c.) move out of the cell
d.) move into the cell
e.) be dissolved
Solutions are categorized as isotonic, hypertonic, and hypotonic based on concentration. If a hypotonic solution surrounds a cell; water will move into the cell. Thus, option d is correct.
What is a hypotonic solution?A hypotonic solution has been defined as a solution that has been known to have a lesser amount of the concentration of the solute dissolved in the solvent. The movement of the ions in a hypotonic solution has been regulated by the osmotic pressure.
Osmosis moves the ions from the concentration from an area with low solutes to the area with higher solute concentration. When hypotonic solution is present outside the cell then the ions move inside the cell resulting in swelling of the cell.
Therefore, option d. in hypotonic solution solute moves inside the cell.
