Answer:
A:The reproductive system produces hormones.
B:The reproductive system transports reproductive cells.
C:The reproductive system produces reproductive cells.
Explanation:
A:The reproductive system produces hormones. : The reproductive organs ovaries in females and testes in males produces hormones. The ovaries produce estrogen and progesterone and testes produce testosterone.
B:The reproductive system transports reproductive cells. : The ovaries in females transfers an egg into the fallopian tube and testes in males secrete sperms at the time of copulation the fertilization of egg and sperm leads to the development of zygote the precursor of new life.

Answer the question, "Why is it best to put subscripts next to the symbols in the density and solubility formulas?"
The number of atoms of each kind is indicated by a subscript following the atom. If there is only one atom, no number is written. If there is more than one atom of a specific kind, the number is written as a subscript following the atom.

Is it a metal, nonmetal, or metalloid?
Which family does it belong to?
How many protons, neutrons, and electrons does its neutral atom have?
Please help with the non-answered ones, following sodium please ^^
Answer:
11
Explanation:
An atomic number of 11 means this atom will have 11 protons. A mass number of 23 means 23 - 11 this atom will have 12 neutrons. Since this atom is neutral the positive protons must be equal to the negative electrons. This atom will have 11 electrons
Answer:
Sodium: Na
It is a metal
It's family is Alkali metals
Its atomic number is 11
It has 12 neutrons, 11 protons, 11 electrons

Which type of selection is shown in the graph above?
A. Disruptive selection
B. Stabilizing selection
C. Disaster Selection
D. Directional selection
In the given graph, the Evolved Population is showing disruptive selection. Hence, the correct option is A. Disruptive selection.
Stabilizing selection is a form of natural selection where individuals with average phenotypes are more likely to survive and reproduce their number. In this selection, the population tends to maintain a stable phenotype. As shown in the graph, the population is maximum for the population having a moderate length of neck.
Disruptive selection is a type of natural selection where extreme phenotypes are preferred over average phenotypes, leading to an increase in genetic variation and the population becoming more diverse. In this type of selection, the population diverges into two or more distinct phenotypic groups. As shown in the graph, two ranges of the population are favored for having traits for extreme lengths of the neck.
