Psych-
Causal attribution theories generally try to explain how we:
1) are influenced by others
2) predict how others will behave based on their attitudes
3) change our attitudes toward other people
4) determine the causes of others' behavior
5) relate to and interact with other people
Causal attribution theories generally try to explain how we determine the causes of the others' behavior based on personal or situational attributions.
This theory was developed by Horald Kelly in 1967, and explains how people attribute the behavior of others according to dispositional (internal) and situational (external) factors.
Dispositional factors are those based on internal characteristics, such as effort and skill. Situational factors, on the other hand, are environmental and external to the individual, such as luck and task difficulty.
Therefore, according to theory we are more likely to attribute the cause of the behavior of others to factors that most coincide with the action.

As soon it cut a piece of an outdoor potted plant and brings it inside and place is it in a vase. A few weeks later, the student notice is that not only is a plant so alive, it has roots. The student plans this cutting into a pot with soil, and he grows along side the original point where it came from. Which explanations best match with the description an image shown here in the scenario? Select all that apply.
Answer:
If its on usa test prep it would be
A) The new root growth is a result of meiosis
B) the new plant formed from as reproduction
D) The new plant is genetically identical to the original plant.
The new plant grows vegetatively from the cutting and will look exactly like the original plant.
Vegetative propagationCutting is a form of vegetative propagation attribute of some organisms.
Cutting a tissue off a plant and the tissue developing its own root to become a new plant happens by mitosis.
Mitotic division of the cut tissues leads to the formation of roots and the eventual growth to a new plant.
Mitotic growth means that the new plant will be genetically and physically identical to the parent plant, provided they grow under the same conditions.

(c) Before treating melanoma cells with capsaicin, researchers pretreated the cells with an inhibitor of
calcineurin. Predict the effect of this pretreatment on the ability of capsaicin to induce apoptosis by the
pathway shown in Figure 2. Provide reasoning to justify your prediction.
(d) Researchers claim that many cancers include a mutation in the gene encoding pGoG. Support the
researchers claim.
Answer:
Explanation:
c. The pretreatment on the ability of capsaicin to induce apoptosis effects in NFAT2 to block ATF3 where it activates ATF3 to inhibit pGoG from inducing apoptosis.
d.AFT3 usually stops pGoG from induce apoptosis and so cancer develops because of apoptosis unable to do it's job and cells just keep dividing which we call a tumor
Which of the following materials is a good electrical conductor?
rubber
ceramic
plastic
copper
Answer:
copper
Explanation:
Copper has the best electrical conductivity of any metal, except silver. A good electrical conductivity is the same as a small electrical resistance. An electric current will flow through all metals, however they still have some resistance, meaning the current needs to be pushed (by a battery) in order to keep flowing.

Lipids include triglycerides, phospholipids, and ____.
A. steroids
B. amino acids
C. starches
D. nucleic acids
The gonads and adrenal glands typically generate the natural steroid hormones from cholesterol. Lipids are the hormones in these forms. Thus, option A is correct.
What is the role of lipid in the body?Lipids serve as the body's energy reserve, control hormones, carry nerve signals, protect key organs, and transport nutrients that are fat-soluble.
Food fat gives texture and flavor, has a high caloric density as an energy source, and helps people feel full.
The body naturally creates hormone-like chemicals, but steroids are synthetic copies of such substances.
They go by the name corticosteroids and are distinct from the anabolic steroids used by athletes and bodybuilders.
Therefore, Lipids include triglycerides, phospholipids, and steroids.

The question is find the slope of the line
Answer:
i do not know
Explanation:
This model chose to include certain features and exclude other features. For example, this simulation only includes rabbits, wolves, and grass but there are other predators of rabbits and other food sources for rabbits. Why do you think the creators focused on these data elements and not others
The creator focused on these data elements and not others because he was trying to create a food chain instead of a food web.
In the ecosystem, the living and non-living things interact over time leading to exchange of energy.
A food chain can be defined as the steps through which energy transfer occurs in an ecosystem.
The energy flows from the producers (grass), primary consumers, (rabbits) and then the secondary consumers (wolves).
The energy flow is indicated with an arrow thus,
grass ---> rabbit -----> wolves.
Food chain, therefore includes linear sequence of organisms.
Food web on the other hand illustrates a complex feeding relationship within the ecosystem.
The food web is made up of a prey that can be eaten by more than one predator.
Therefore, even though there where other predators of rabbits and other food sources for rabbits, he chose only few features to create a food chain.

Answer:
hydrolysis reaction
Explanation:
Hydrolysis reactions are the reverse of condensation reactions. In a hydrolysis reaction, a larger molecule forms two (or more) smaller molecules and water is consumed as a reactant. Hydrolysis ("hydro" = water and "lysis" = break) involves adding water to one large molecule to break it into multiple smaller molecules.
