What is the difference between primary & secondary succession? *
Primary succession: is a process by which a community arises in a virtually lifeless area with no soil.
Secondary succession: follows a disturbance that destroys a community without destroying the soil.
Answer:
Explanation:
In primary succession, newly exposed or newly formed rock is colonized by living things for the first time. In secondary succession, an area previously occupied by living things is disturbed—disrupted—then recolonized following the disturbance.

Dino and his family live in a community where people just throw their garbage anywhere. Recently, Dino was hospitalized due to diarrhea. His sister is now afflicted with dengue, and his father has lost his job because of tuberculosis. On space provided, discuss the possible causes of the health problems in Dino's family. What can be done to alleviate their situation? I NEED IT RIGHT NOW PLS! I cant find the subject Science cuz this is in science
Answer:
The main measure that must be taken to alleviate this situation is the proper disposal of garbage in the community in which Dino lives.
Explanation:
Inadequate disposal of garbage can cause a series of very serious illnesses and accidents to the entire community, which reinforces the need for all residents of a community to promote the proper disposal of waste. This is not happening in the community where Dino and his family live.
The inadequate disposal of garbage can contaminate the water and food of the community, causing diarrhea in Dino. This garbage also caused the accumulation of standing water, allowing the dengue mosquito to develop and infect his sister. In addition, garbage has created a suitable environment for maleficent microorganisms, such as the bacteria that causes tuberculosis.

Why do plants of the fields become yellowish?
Answer:
Poor drainage or improper watering
Explanation:
Water issues — either too much or too little — are the leading reason behind yellow leaves. In overly wet soil, roots can't breathe. They suffocate, shut down and stop delivering the water and nutrients plants need. Underwatering, or drought, has a similar effect.

An EMT reaches the scene of a car accident, disinfecting and dressing a man's head wound that has been bleeding profusely. Upon taking off his bloodied latex gloves, he notices that a shard of window glass has penetrated one glove and cut is palm. Years later, long retired after a second career as an accountant, he is surprised to discover that he has liver cancer. Thinking back, he recalls having received both hepatitis vaccines available at the time of the exposure, and guesses that he may most likely have been exposed to __________.
Answer: hepatitis C.
Explanation:
Based on the information given in the question, it's most likely that the person has been exposed to hepatitis C.
Hepatitis C is an infection that is caused when a virus attacks the liver which leads to the inflammation of the liver. Since the person reaches the scene of a car accident, it's possible that the EMT got in contact with the contaminated blood. In this case, he most likely have been exposed to hepatitis C.

Why is an imbalanced high population of moose on the island seen as a
problem? *
If the moose population continues to grow, they will run out of space on the island and
take over the wolf niche.
If the moose population is unchecked, the local balsam fir population will be
decimated, leaving a barren ecosystem.
It was not seen as a problem; science believes we should let the ecosystem run its
course and dies out.
It was not seen as a problem because the absence of wolves on the island ensured
the future of the ecosystem.
Answer:
If the moose population is unchecked, the local balsam fir population will be decimated, leaving a barren ecosystem.
Explanation:
The imbalanced high population of moose on the island seen as a problem because it decreases the local balsam fir population which is a major food source for the moose in the winter season. If the population of moose is grow higher then the scarcity of food sources occurs and the food source will be eliminated from that ecosystem. If the moose population increases the local balsam fir population will be eliminated from the ecosystem and the land will remain barren or without vegetation.

Oy=12
Oy=6
Oy=5
y=2
If x and y vary inversely and x=3 when y=8, then y will be 6 when x=4. Therefore, option (B) is correct.
What is the value of Y?If x and y vary inversely, it means that their product remains constant. Mathematically, we can write this as x * y = k, where k is a constant.
We are given that x = 3 when y = 8. Using the formula above, we can find the value of k:
x * y = k
3 * 8 = k
k = 24
Now we need to find y when x = 4. Again, using the formula above:
x * y = k
4 * y = 24
y = 6
Therefore, the option is Oy=6.

1. Explain the justification for and the circumstances surrounding the internment by the US government of Japanese Americans during World War II.
Answer:Under the Executive Order, some 112,000 Japanese Americans—79,000 of whom were American citizens—were removed from the West Coast and placed into ten internment camps located in remote areas. Japanese Americans were given only a few days' notice to report for internment, and many had to sell their homes and businesses for much less than they were worth. In so doing, they lost much of what they had accrued in the course of their lives.
The camps—like the one at Manzanar, California, located at the foot of the Sierra Nevada mountains—were surrounded by fences, barbed wire, guard towers, searchlights and machine guns. Families incarcerated in the camps lived in uninsulated cabins or converted stables. They occupied their enforced idleness by organizing schools and camp newspapers, by running barber or beauty shops, and more. A small number were cleared for work outside the camps. Fred Korematsu was an American-born twenty-three-year-old welder of Japanese descent living in the San Francisco Bay area. In May 1942, he was arrested for failing to comply with the order for Japanese Americans to report to internment camps.
With the help of the American Civil Liberties Union, Korematsu sued on the grounds that as an American citizen he had a right to live where he pleased.
But in a 6-3 decision in Korematsu v. United States the Supreme Court ruled that interning Japanese Americans during the war for purposes of "military necessity" was constitutional.

Which scenario would result in a decrease in population size, or a negative population growth?
Use this formula:
population growth = (birth rate + immigration) – (death rate + emigration)
0 individuals emigrate, 14 individuals die, 14 individuals are born, 14 individuals immigrate
40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate
12 individuals emigrate, 5 individuals die, 17 individuals are born, 0 individuals immigrate
19 individuals emigrate, 4 individuals die, 25 individuals are born, 0 individuals immigrate
Answer:
The third situation has the lowest amount of people with 0.
Explanation:
In this situation,
0 individuals emigrate, 14 individuals die, 14 individuals are born, 14 individuals immigrate. Population growth = 14
In this one,
40 individuals emigrate, 0 individuals die, 10 individuals are born, 28 individuals immigrate Population growth = 2
For this one,
12 individuals emigrate, 5 individuals die, 17 individuals are born, 0 individuals immigrate Population growth = 0
Last one,
19 individuals emigrate, 4 individuals die, 25 individuals are born, 0 individuals immigrate Population growth = 2.
