Explain why an increase in precipitation and in the number of nearby factories has a greater impact on the occurrence of the mari flowers than changes in temperature, length of day, and invasive species
Advanced rainfall during the growing period can lead to an improvement in the utilization of soil water, which is beneficial to root growth.While rain clearly affects food supply, it also can affect foraging behavior, reproductive and population growth rates, and competitive interactions in subtle ways that might be difficult for researchers to trace back to any particular sourceThe increase of precipitation and number of nearby factories has a greater impact on the occurrence of mari flowers because some types of precipitation has acid in it, and the acid has a high pH level. All of those chemicals have higher pH levels than changes in temperature.

Why are most oceanic trenches found in the Pacific Ocean?
Answer:
It's where the subduction zones are.
Explanation:
Subduction zones - when two plates meet and one gives way to the other.
Answer:
Most oceanic trenches found in the Pacific Ocean because it is the largest ocean, therefore it has most most convergent boundaries. Whenever a convergent boundary is formed it creates a trench because the oceanic plates are denser the continental plates so they sink. This is known as subduction.
Which cell would doctors conclude is a cancerous mass?
A. A
B. B
C. C
D. C
The correct answer is A
Explanation:
Cancer including cancerous mass or tumors is caused by an abnormal and uncontrolled reproduction of cells. This means cell division occurs faster than normal and leads to damaged or malfunctioning cells. Moreover, in terms of the number of cells vs time, cancer leads to a high number of cells in a short time. This occurs in cell A because different from cells B, C, and D, this has increased the number of cells in a short time, while others have decreased over time or remain constant. According to this, the cell that is a cancerous mass is A.

O B. How much carbon is found in Earth's crust?
O C. What are the naturally occurring states of carbon?
D. What is the configuration of carbon's valence shell?
Answer: A is the answer
Answer:
D. What is the configuration of carbon's valence shell?
Explanation:
Carbon is considered special and very versatile because of the number of valence electrons it has. Because it has four valence electrons, it's able to combine with many other elements, which makes it an essential building block of life.

Question 2 (2 points)
Which of the following best explains why matter must travel through cycles?
a
There is an unlimited amount of matter in the universe, so it can take on any form at
any time.
b
There is a fixed amount of matter in the universe, so it must take on different forms
at different times.
Elements flows within ecosystem in various ways. It is important for matter to travel through cycle as there is a fixed amount of matter in the universe, so needed to be recycled.
What is cycling of matter?Matter cycling is movement of matter from one form to another or from one place to another on the Earth, inside its ecosystems.
Matter is constantly cycling from place to place, and this can have both positive or negative effects. Matter also cycles naturally, or can be due to human activity.
As there are only finite number of nutrients on the Earth, so, it is necessary for them to be recycled in order to ensure the continued existence of living organisms.
Thus, option b is correct.

Hydroponics is defined as the practice of growing plants without soil used to provide support or nutrients or ‘Soilless Farming'. How is ‘Hydroponics' an effective method of farming in arid and dry zones other Earth?
Answer:
Hydroponics solves the problem of unavailability of water in those arid and dry regions
Explanation:
As rightly stated in the question, hydroponics is a practice that involves the culturing of plants without the need for soil. Hydroponics procedure make use of a moisture-containing solution filled with nutrients.
This procedure of hydroponics, however, comes with some disadvantages but one major effectiveness it has in arid or dry regions is that it SOLVES THE PROBLEM OF WATER UNAVAILABILITY. When it comes to farming practice using soil, constant water supply is an unnegotiable criterion because water is needed for the growth of plants in the soil.
However, in arid regions, which are usually very dry due to lack of rainfall, the practice of hydroponics can substitute for soil farming in order not to cause food scarcity.
