C. Usually when an atom loses or gains an electron, it is because it is trying to satisfy the Octet Rule. The Octet Rule states that an atom is at its stablest when it has 8 valence electrons (two in helium's case)
If you look on the periodic table, elements on the left (Alkaline Metals) are the most reactive because they only have one valence electron (or electron in the outer shell). Elements on the right (Noble Gases) are the least reactive because they have a full outer shell of 8 valence electrons.
Later on you will find that as stability decreases as you go down the periodic table but that is a discussion for a different time.
<span>This question is based on conservation of energy as the work done would lead to change in kinetice energy of car
change in KE = 1/2 mv(f)^2 - 1/2mv(i)^2 = 1/2m(v(f)^2-v(i)^2)
where v(f) and v(i) are the final and initial speeds
change in KE = 185kJ = 185,000J = 1/2 m((28m/s)^2-(23m/s)^2)
185,000=1/2 m(255m^2/s^2)
solving for m
m=1451kg</span>
The therapeutic technique Lucinda would start is behavioral self-monitoring.
<u>Explanation:</u>
Behavioral self-monitoring, introduced by Mark Snyder in the 1970s, is an ability of an individual to regulate the behavior to accommodate in various social situations.
Here, Lucinda frequently gets upset and yells at her husband, co-workers, and friends. She wants to keep a record of where, when, or with whom she might lose her temper in order to evaluate her behavior.
The individuals with high levels of self-monitoring possess greater skill at bridging social situations and in relationships they seem to be more flexible and adaptable.
The phenomenon of "weightlessness" occurs when there is no force of support on your body. When your body is effectively in "free fall", accelerating downward at the acceleration of gravity, then you are not being supported.
Asexual reproduction is a type of reproduction that only requires one parent. The offspring only have the characteristics and traits from that parents. They create “clones” if you will. This is the most common form of reproduction for single cell organisms like prokarayotes and bacteria.
Here are the advantages:
1. Rapid Populating
Asexual reproduction gives the ability to produce large quantities of of offspring. This helps to fill up niche’s quickly and prevent intruders and competition from invading.
2. No Mates Required
Finding a mate can be very difficult for organisms that are in desolate environments, like the deep ocean. Asexual reproduction takes the need to find a mate away, allowing these organisms to multiply.
3. In Case of Emergency
In dire situations, plants and organisms can keep themselves alive and produce others to help them without the help of a mate, or other reproductive source. Plants are a great example of this. If no pollinator is available to pollinate, then they can clone by asexual reproduction.
4. No True Investment
Asexual reproducers do not have to carry their offspring for a long amount of time and produce more than one at a time. This makes it a quick and inexpensive process for them in the terms of time.
Here are the disadvantages:
1. No Diversity
Since the traits of only one parent is passed on, all of the offspring are exactly identical. This causes for a very big lack of diversity among the population of these organisms.
2. Prone To Extinction
All of the same traits also means all of the same weaknesses. Parasites and other predators that have evolved to kill just one of the organisms can take out the entire population.
3. Cannot Adapt
An organism has established reactions to certain things, and all of these reactions are passed down to their offspring with asexual reproduction. This makes it impossible for them to adapt to any environment changes.
