5 0

Answer:

Explanation:

a)

Even if a periodic table is not color coded, we can still find elements with the same chemical properties. This is easy because when we look at the group to find the elements, we see those that have similar chemical properties.

As an example, the Elements of group 1 forms basic oxides. This is a general chemical property of all group 1 elements.

b)

They have similar chemical properties because all the elements in any group has the same number of valence electrons.

c)

Lithium, Sodium and Potassium.

They're all elements of group 1, they all have 1 valence electron

For two autosomal dominant genes, what is the probability that a cross between two heterozygotes (i.e. AaBb x AaBb) will produce
oksian1 [2.3K]

Answer:

1 in 16

Explanation:

When two heterozygotes (AaBb x AaBb) for two autosomal genes are crossed the expected probability for the offspring is 9 A-B-, 3 A-bb, 3 aaB- and 1 aabb. In other words, out of sixteen offspring, 9 are expected to be dominant on both genes (either homozygous AA or BB or heterozygous Aa or Bb), 3 are expected to be dominant on the A gene but recessive on the b gene, 3 are expected to be recessive on the a gene but dominant on the A gene, and only 1 is expected to be recessive on both genes aabb.

Answer:

The given situation is an example of the <u>Positive feedback loop</u><u>.</u>

Explanation:

Positive feedback is the phenomenon in which the effects of the small disturbances on a particular system can result in an increase in the perturbation magnitude. Positive feedback increases the input and causes instability in the system. Therefore, it refers to positive loop gain about closed loop of the cause and effect.

<u>Therefore, the given situation is an example of the </u><u>Positive feedback loop</u><u>. </u>
