The first can be filled with an element and the second blank can be filled with a compound.
Iron is an element as it contains only one kind of atom, which combines with the oxygen from the air to produce rust, that is, iron oxide. The rust comprises two kinds of atoms, which signifies that it is a compound. A compound refers to a molecule that comprises at least two types of atoms. In the case, iron oxide is a compound as it comprises Fe and O atom.
Answer:
phages are non-living biological entities that can produce numerous copies of themselves, forming ordered three-dimensional structures on a nanometre scale
Explanation:
A phage (i.e., a bacteriophage), is a virus capable of infecting and replicating within bacteria. Bacteriophages are composed of proteins forming a capsid that encapsulates the genetic material (either DNA or RNA genome), which may contain a variable number of genes. Bacteriophages, and viruses in general, can be considered nanomachines capable of producing numerous copies of themselves with high fidelity by utilizing the molecular machinery of the host bacterial cell. In biotechnology, it has been proposed to exploit the knowledge about bacteriophage reproduction to design diverse nanostructures.
Ok, colour blindness and blood type are independently assorting traits, that means that having one does not affect having the other, the question even tells you that the traits are on different chromosomes.
<span>To answer your question we'll have to calculate the probability of both traits in the child and then multiply them together to get the overall probability of both being present in the child. </span>
<span>Let's start with blood type: there are four types of blood type: AB, A, B and O. Blood type is determined by what protein each chromosome codes for: so if one chromosome is I^A and codes for A type protein, while the other is I^B and codes for B type protein, then the overall blood type will be AB. O blood type is recessive, it doesn't code for any protein at all and is given the symbol i. </span>
<span>Since both parents are type A and their first child is type O, you know that both parents are heterozygous for blood type A, meaning that one chromosome they have is I^A and the other is type or or i. For a child to be blood type O, each parent has to give their type O chromosome to the child. There is a 1/2 chance that one parent will give the recessive O chromosome, so for both parents to give their recessive allele the probability is 1/2 * 1/2 = 1/4 </span>
<span>Colour blindness is an X-linked condition, that means that women can be carriers but not manifest the colour blindness because they have one "good" X chromosome which masks the recessive colourblindness gene on the other X. The father cannot have a colourblindness gene or else he'd be colourblind himself, since he's only got 1 X-chromosome. Because dad has healthy eyesight, any girls he has will have healthy eyesight too, since his X will always be healthy and mask the X from mom if she happens to give the recessive colourblind gene. So the probability that the girl will have normal vision is 1/1. </span>
<span>However, it is not a given that the baby born will be a girl, there's a 50/50 chance that it'll be one or the other sex, so we need to consider the probability involved with the child being a girl. this probability is 1/2. </span>
<span>So now we multiply all our probabilities together to calculate what the chances of a normal visioned, type O blood typed girl is: </span>
<span>Normal vision (1) * blood type O (1/4) * girl baby (1/2) = 1/8 </span>
<span>So your probability is 1/8! </span>
<span>Hope this helps :)</span>
Because they contain less "built-in" water.
Explanation:
When two glucose molecules 'decide' to bond, they lose a molecule of water:
<span>2<span>C6</span><span>H12</span><span>O6</span>→<span>C12</span><span>H22</span><span>O11</span>+<span>H2</span>O</span>
And this happens at every connection between glucose molecules, so in a long chain a lot of water is lost. The water does not contribute anything to the energy content of the compound.
Answer:
Sistemas orgánicos
Explanation:
Aunque cada órgano del cuerpo realiza sus funciones específicas, los órganos también funcionan juntos por grupos, a los que se denomina sistemas orgánicos (ver Principales sistemas orgánicos). Los médicos clasifican las enfermedades y sus propias especialidades médicas de acuerdo a los diferentes sistemas orgánicos.
