Answer:
A single replacement reaction occurs when an element reacts with a compound to produce a new element and a new compound. It can only occur when the element that is doing the replacing is more reactive than the element that is being replaced. Therefore, it is useful to have a list of elements in order of their relative reactivities. The activity series is a list of elements in decreasing the order of reactivity. Since metals replace other metals, while nonmetals replace other nonmetals, they each have a separate activity series.
There are two types of single replacement reactions:
A metal replaces another metal that is in solution:
A + BC → B + AC
Example: Zn + CuC[tex]l_{2}[/tex] → Cu + ZnC
A halogen replaces another halogen that is in solution:
A + BC → C + BA
Example: Br[tex]_{2}[/tex] + 2KI → I

g Two linked genes, (A) and (B), are separated by 18 centiMorgans. A man with genotype Aa Bb marries a woman who is aa bb. The man's father was AA BB. What is the probability that their first child will both be ab/ab
Answer:
The probability that their first child will both be ab/ab = 41%.
Explanation:
Available data:
Two linked genes (A) and (B) ⇒ 18 centiMorgans apartMan ⇒ Aa BbMan´s father ⇒ AA BBWoman ⇒ aabbThe recombination frequency is given by the distance between genes. We have to know that 1% of recombinations = 1 map unit = 1cm.
Recombination frequency = 0.18
Man: AaBb
Gametes) AB Parental
ab Parental
Ab Recombinant
aB recombinant
18 centi morgan = 18 % of recombination in total
= % aB + % Ab
= 9% aB + 9% Ab
100% - 18% = 82% of parental in total
= % of AB + % ab
= 41% AB + 41% ab
The frequency for each gamete is:
AB 41%
ab 41%
Ab 9%
aB 9%
Cross: man x woman
Parental) AaBb x aabb
Gametes) AB, Ab, aB, ab ab, ab, ab, ab
Punnett square) AB ( 41%) Ab (9%) aB (9%) ab (41%)
ab AaBb Aabb aaBb aabb
ab AaBb Aabb aaBb aabb
ab AaBb Aabb aaBb aabb
ab AaBb Aabb aaBb aabb
F1) 41% of the progeny is expected to be AaBb
9% of the progeny is expected to be Aabb
9% of the progeny is expected to be aaBb
41% of the progeny is expected to be aabb
How have humans impacted the planet?
How this contributed to climate change?
Give at least 5 examples.
Answer:
humans have impacted the planet by building and changing the envoirment in order to surive
Explanation:
this impacted climate change because
1- polluion- gases for the companies that human built polluted the air
2- disturb wildlife- building/constructing things can impact animal shelter
3- overpopulation- having too many people in one area is harmful to the emviorment as well as leading to climate change over time
4- burning of fossil fuels- increased greenhouse effect
5- farming lifestock

Which statement about the members of a population that live long enough to reproduce is consistent with natural selection?
A.They transmit characteristics aquired by use and disuse to their offspring
B.They tend to produce fewer offspring than others in the population
C.They are the ones that are best adapted to survive in their environment
D.They will perpetuate unfavorable changes in the species.
Answer:
It's option B
Explanation:
Organisms which can't survive harsh times and have a small lifespan make huge amount of offsprings like ants. While long living animals make fewer offsprings like humans, whales, tortoises.

A white blood cell (WBC) encounters bacteria in a scrape on the knee of a child who has fallen off of his bicycle. The WBC’s job is to take the bacteria inside of itself and destroy the bacteria. If the bacteria cannot be moved across the WBC membrane, how will the WBC most likely take it in?
Answer:
The correct answer is - phagocytosis.
Explanation:
Phagocytosis is a type of endocytosis that also engulfs the solid material including microbial pathogens like bacteria and others. In immunity response macrophages, neutrophils and. immature dendritic cells are white blood cells that perform the phagocytosis process to kill the microbes and antigens.
Phagocytosis ingests and digest pathogens and develops an adaptive immune response an essential part of the innate immune system. WBC will most likely take it in through phagocytosis in the given case.
