Well, it's almost impossible to give you the correct answer as you haven't attache the picture which shows the needed data. I bet that you have the same question as the most of students that's why I will try to help you. If you had to share this pic, the answer should be <span>Uterus. Hope Iguessed right!</span>
Answer: The father determines the biological sex of a baby
Explanation: Human beings have two sex chromosomes, males have XY chromosomes whereas females have XX chromosomes. During fertilization, an egg from a woman fuses with a sperm cell from a man to form a zygote. Women have two X chromosomes (XX) and any point in time they can only release an egg bearing an X chromosome but males have one X and one Y chromosome, therefore they can either release a sperm cell with an X chromosome or a sperm cell with a Y chromosome. When an egg with X-chromosome fuses with a sperm cell with an X chromosome, the resulting baby is a female but when an egg with an X chromosome fuses with a sperm cell with a Y chromosome, the resulting baby is a male.
What makes the difference in both sexes is the Y chromosome from the man, therefore the father determines the biological sex of a baby.
Answer:
Robert Hazen’s studied enviromental and biological processes that might have been critical for life, and also for the formation of approximately two-thirds of Earth's mineral species (see Hazen et al., 2008; Gonzalez & Richards 2020)
.
Explanation:
Hazen provided evidence about how first organic molecules were generated on the primitive earth millions of years ago. He observed that high-pressure hydrothermal vents may provide food for underwater ecosystems. It represents a piece of critical evidence on the origin of life.
You can read these articles that are certainly clarifying in the description of his experiments and discoveries:
