If 5x+4y=58 and 3x + 7y = 67 find the value of ( x + y )
Explanation:
5x + 4y = 58 ....1
3x + 7y = 67 ....2
....1 × 3 both sides of the equation
15x + 12y = 174 ....3
....2 × 5 both sides of the equation
15x + 35y = 335 ....4
.....4 - ......3 both sides of the equation
35y - 12y = 335 - 174
23y = 161
y = 161/23
= 7

4. Root cells of plants take in some minerals from the surrounding soil by spending
energy. After the plant obtains enough minerals to maintain health, the plant will
continue to absorb minerals from the soil. Which reason best explains why root cells
need to spend energy in order to transport some minerals into cells?
Answer:
i know its 3
Explanation:
yes buddy
After the plant obtains enough minerals to maintain health, the plant will continue to absorb minerals from the soil.
This is because Mineral concentration is higher in root cells than in the surrounding soil. Thus option D is correct.
What are the effects of minerals do plants growth ?
For a better growth plants need minerals, can be absorbed through the roots by active transport in the form of mineral ions.
Minerals have a major role in electron transport, enzyme activation, development, maintenance of structural components etc.
The two most essential minerals are magnesium ions and nitrate ions needed for proper growth of plants.
Beside this various fertilizer are used like Nitrogen fertilizers which increase the growth as well as high yield of the crops.
Excess use of mineral cause mineral toxicity, for example eutrophication happens when excess nitrate enters into aquatic system causes the death of aquatic animals.

Which phrase best defines a prototype?
the final product, which has undergone extensive testing and redesign
a model that has been redesigned and retested several times
the criteria established to help solve a problem
O a model from which later versions are developed
Answer:
A model from which later versions are developed.
Explanation:
A prototype is the rough draft of something in a sense, it is not yet complete and is often only the most basic idea to be expanded on in later versions.
The best definition for a prototype is a model from which later versions are developed. Therefore option D is correct.
A prototype is an early or preliminary version of a product, system, or design that is created to test and evaluate its functionality, features, and feasibility. It serves as a proof of concept and helps in identifying any flaws or areas that require improvement before the final product is developed.
The final product, which has undergone extensive testing and redesign, does not accurately define a prototype because a prototype is not the final product but rather an initial version created for testing and refinement.
Therefore, the most accurate definition, emphasizes that a prototype is a model or early version of a product or system that serves as a foundation for the development of subsequent versions based on testing and feedback.

Answer: it reproduces by cell division
the answer should be ..............
D. uses mitosis
Explanation: here is the Wikipedia explanation im not good at explaining
Most yeasts reproduce asexually by mitosis, and many do so by the asymmetric division process known as budding. With their single-celled growth habit, yeasts can be contrasted with molds, which grow hyphae. Fungal species that can take both forms (depending on temperature or other conditions) are called dimorphic fungi.
Answer:
Is very fast
Explanation:
First of all, you're not "dumb"!
Yeast reproduction happens relatively quickly (in a matter of hours, not a matter of days). It CAN occur by mitosis, but most often occurs by a process called budding.
Humans have a "slow" reproduction - it takes 9 months just to produce a single organism!
