HELPPPP !! For horticulture
Answer:
The SAE curriculum includes practical farming tasks conducted outside the scheduled classroom and laboratory period by students. SAEs offer a method for students in agricultural education to gain real-world work opportunities that they are most interested in in the field of agriculture. Supervised agricultural experience is an essential component of agricultural education, and all Agriculture, Food and Natural Resources (AFNR) courses are a necessary component.

1. Calculate the number of moles in each of the following masses:
a. 64.1 g of aluminum ans: 2.38 mol Al show work
Answer:
2.38 mol of Al
Explanation:
To find the number of moles in a substance, you simply divide by the atomic mass. In this case, the conversion table would look as follows:
[tex]\frac{64.1 g}{1}[/tex] * [tex]\frac{1 mol}{26.98 g}[/tex]
The gram units cancel, and you are left with the answer of about 2.38 moles of Aluminum.

Why do some transition metals have multiple oxidation states?
Transition metals have multiple oxidation states because of their (a. completely filled b. partially filled c. empty) (s, p, d, or f) sublevel.
Answer:
because of energy difference between (n1)d and ns orbitals (sub levels) and involvement of both orbital in bond formation
Explaination:
the reason is that there is a difference in energy of orbitals of an atom of transition metal, so there (n1)d orbitals and there ns orbitals both make a bond and for this purpose they lose an electron that is why both sublevels shows different oxidation state.
Hope this helped you
Transition metals have multiple oxidation states because of their partially filled orbitals . Thus option b is correct.
What are transition metals?Transition metals are defined as essentially, a configuration attended by reactants during complex formation, as well as the reaction coordinates.
It can also be defined as a very short-lived atomic configuration at a reaction-energy diagram's local energy maximum.
Transition metals are best defined as an element with a partially filled d sub-shell on its atom or that can give rise to cations with an incomplete d sub-shell.
Transition state is defined as a chemical reaction is defined as a certain configuration along the reaction coordinate.
Oxidation state is defined as the total number of electrons that have been deleted or added to an element.
It can also be defined as an atom's charge if all of its links to other atoms were entirely ionic.
Thus, transition metals have multiple oxidation states because of their partially filled orbitals . Thus option b is correct.

Match each description below with the name of the local wind system being described. warm, dry downslope wind affecting Southern California monsoon wind blowing from a valley up a mountain slope valley breeze a seasonally changing wind Santa Ana wind generated by cold thunderstorm downdrafts haboob
Answer:
warm, dry downslope wind affecting Southern California - Santa Ana wind
a seasonally changing wind- monsoon
wind blowing from a valley up a mountain slope - valley breeze
generated by cold thunderstorm downdrafts - haboob
Explanation:
The Santa Ana wind occurs in early autumn. They bring hot and dry weather to areas around the South-West coast. They move at high speeds, affecting most parts of Southern California.
Monsoon is a seasonal wind that blows across Southern Asia. It usually blows in summer. It is a a seasonally changing wind.
Valley breeze is an example of convection current in nature. It is produced by rapid warming of the valley floor leading to the expansion of air making it to flow up the slopes. At night, radiation from the surface cools the slopes. This leads to the rise of cooler and denser air which drains into the valley.
Haboob is generated by cold thunderstorm downdrafts. It is associated with large sandstorms and dust storms.

Answer/Explanation:
A theory has lots of scientific evidence to back it up. We know this to be true based on lots of different diseases and studies of their spread.
A hypothesis is more of a starting point - an educated guess based on limited evidence. It requires further testing before becoming a theory.
A law is something that can be generalized to lots of contexts, and is universal. Such as the law of thermodynamics.

Answer:
one that reduces a bean plant's ability to make food
one that increases the plants susceptibility to disease
Explanation:
Genetic mutation refers to the changes in the arrangement of the bases that make up a gene. This sudden change may have positive or negative consequences for the individual specie.
Some genetic mutations actually alter a gene's sequence of bases but do not alter the function of the particular protein that the gene in question makes.
