Answer:
A - 3:1
Explanation:
In order to determine what number of offspring will have attached earlobes, we must make a Punnett table. We know that attached earlobes are the dominant gene, and we know unattached earlobes are recessive.
| P | p
——————-
P | PP | Pp |
——————-
p | Pp | pp |
As we can see, only one out of the four squares has two recessive genes. Therefore, our answer would be A - 3:1.
They say that is the individual who is a person who once lived but is now dead and studied genetics know as Gregor Mendel
The mitochondria is a double membraned organelle, the inner of these membranes is invaginated to form structures called cristae. The fluid inside is called the mitochondrial matrix. The mitochondria has a pivotal role in the creation of ATP in aerobic cellular respiration. Glycolysis occurs outside the mitochondria, producing pyruvate and ATP, the pyruvate endures the link reaction on its way into the mitochondrial matrix and turns into acetyl co enzyme A. This acetyl group is used in the matrix in what is called Krebs cycle, where the oxidation of acetyl groups is coupled with the reduction of hydrogen carriers. The products of Krebs cycle are then transported to the electron transport chain on the cristae where the reduced NADH and FADH are then oxidized. The remaining hydrogen electrons are transported down the chain where an oxygen molecule is reduced to water. Chemiosmosis also occurs at the electron transport chain, in which hydrogen protons move down the concentration gradient (from the inner mitochondrion membrane) through an ATP synthase where ATP is generated. The multiple folds inside the mitochondria which are the cristae, mean that there is plenty of surface area for cellular respirations to occur at.
Answer:
In biology, tissue is a cellular organizational level between cells and complete organs. A tissue is an ensemble of similar cells and their extracellular matrix from the same origin that together carry out a specific function. Organs are then formed by the functional grouping together of multiple tissues.
The answer: Ventricles.
There are four ventricles in the brain all connected between them,
where the cerebrospinal fluid is produced. There is a choroid plexus in each ventricle that produce the fluid.
The four ventricles:

-third ventricle<span>
- fourth ventricle</span></span>
