Answer:
Four major factors affect reactivity of metals: nuclear charge, atomic radius, shielding effect and sublevel arrangement (of electrons). Metal reactivity relates to ability to lose electrons (oxidize), form basic hydroxides, form ionic compounds with non-metals.
Explanation:
The baby’s GENOTYPE would be OO or Xo Xo as O blood type is a recessive trait and needs 2 O’s to appear. The mother would have to be Xa Xo or AO. Which would mean that the Baby received the O from the mother meaning that they would have to receive another O from the father.
Male 1: cannot be the father because he cannot pass a O allele
Male 2: can be the father if his genotype is AO as the mothers is
Male 3: is most likely the father as his genotype is OO meaning he has more of a chance to give off that allele
Answer:
green-flowered plants
Explanation:
In biology, blending inheritance refers to an erroneous theory from the XIX century, which proposed that the progeny (F1) inherits phenotypic traits as an average of parental phenotypic values. If this theory would be true then a crossing of a blue flower variety with a yellow variety of the same species would produce green-flowered progeny (since green is a combination of blue and yellow). Charles Darwin used pangenesis, a hypothetical mechanism for heredity that implied blending inheritance, in order to understand the transmission of hereditary characters. Darwin believed that different parts of the body generated heredity particles called 'gemmules' that aggregated in the gonads, and contributed to the transmission of heritable information to the next generation. The blending inheritance theory was replaced by Mendelian inheritance during the early 1900s.
Answer:
Positive feedback.
Explanation:
An increase in body fluids causes increase in kidney filtration which leads to higher production of urine, this type of feedback is known as positive feedback because when there is increase in the output, this is called positive feedback while on the other hand when there is decrease in the output we called it negative feedback. So we can see that the output of the kidney is higher concentration of urine so we can say that it is a positive feedback.
<span>Bone density is not a health-related fitness
component. There are only five health-related fitness components and these are: <span>
<span>a.
Cardiovascular Endurance - refers to the ability of your circulatory and respiratory systems, how they
work together.</span>
b.
Muscular Strength - the maximum amount force that your muscles can exert in one
effort.
c.
Muscular Endurance - the ability of your muscles to perform without feeling
easily fatigued.
d.
Flexibility - the ability of your joints to move and bend through a full range
of motion.
e. Body
composition - refers to the proportions of your lean and fat tissue.
<span>Exercises
that improve cardiovascular fitness tend to improve body composition because
they release energy. When the body exercises, stored energy is expelled through
respiration and processes in the cells. With this, fat is used up as a source
of energy and is then burnt and released giving way to improved body
composition.</span></span></span>
