Answer:
Yes, the model of the helium atom is showing an ion.
Explanation:
Helium, with an atomic number of 2, should have 2 protons and 2 electrons; however, the model only depicts 1 electron. That means the helium must have lost an electron, making it a +1 charge and an ion.
Answer:
Ben - Y Xc
Jen - XCXC
Violet - XCXc
Seraphina - XCXc
Samuel- Y Xc
Explanation:
Given -
Ben has a cleft chin
Let the allele for cleft chin be "c"
and the allele for normal chin be "C"
When Ben with cleft chin mates with wife Jennifer Garner having normal chin, then the two girl child do not have cleft chin but the boy has cleft chin.
This means that the allele C could be X -linked and the mother is not the carrier but the father is
The genotype of father Ben would be Y Xc
Genotype of mother would be XCXC
Genotype of two daughters XCXc , XCXc which means they are carrier for the next generation
Genotype of Boy - Y Xc
Answer;
-Down the concentration gradients; evenly distributed
Diffusing molecules move down the concentration gradients until they are evenly distributed.
Explanation;
Diffusion is the movement of particles from an area of higher concentration to an area of lower concentration.
-Whenever a substance exists in greater concentration on one side of a semipermeable membrane, such as cell membranes, any substance that can move down its concentration gradient across the membrane will do so. If the substances can move across the cell membrane without the cell expending energy, the movement of molecules is called passive transport.
-The mechanism of molecules moving across a cell membrane from the side where they are more concentrated to the side where they are less concentrated is a form of passive transport called simple diffusion.
The answer is A, bacteria can move around, use energy, and reproduce just like humans can, the only difference is they're single cell and we're not.
