Answer: Options A,B,C, and F
A. Global climate changes.
B. Atmospheric changes.
C. Predator-prey relationships.
F. Radiation of numerous terrestrial groups.
Explanation:
Due to increasing natural disasters (such as volcanic eruption) and arthropological activities (such as mining) that led to the emission of harmful gases, changes in the atmosphere and overall climatic conditions is established.
They saturate the atmosphere and due to limited carbon sinks to absorb them, they alter the climatic parameters like temperature, rainfall, and relative humidity.
The effects of change in climatic parameters are flooding, habitat destruction, increased predation, and among others. Thus, leading to dispersal of some animal species and decline of many others.
Predator-prey relationship also plays an important role in the expansion (likely through migrating from danger) and in most cases decline of some animal species, especially when there's limited prey species to go round for the predators.
Which is an example of a physical change?
A. Wood rots.
B. Water evaporates.
C .A nail rusts.
D. Gasoline ignites.
Answer: Water Evaporates
Explanation: When water changes from a liquid to a gas it isn't going under and chemical reaction it's just evaporating. But when Wood rots, A nail rusts, and gas ignites those are all undergoing a chemical change

Why does a buzzer starts to buzz as soon as the circuit is complete?
Answer:
The circuit is complete again and the the electric charges start to flow. ... Depending on the distance between the electromagnet and the nail, the rigidity of the rubber band and the strength of the electromagnet, the circuit can be broken and completed several times a second. Hence you hear a buzzing sound
Answer:

The government of a flood prone region wants to implement some measure to reduce risk of floods. Which method is likely to reduce the risk of floods in that region
Answer:
The correct answer is "preservation of wetlands".
Explanation:
Wetland are areas of lands that are saturated with water, usually comprised by marshes or swamps. Preservation of wetlands help to reduce the risk of floods because wetlands temporarily store and slow the release of stormwater. It has been reported that areas where wetland have been lost, the chances of flood increases by as much as 80 percent. The government of a flood-prone region would likely reduce the risk of floods by preserving its wetlands.

Labor has three different stages 1st (dilation), 2nd (expulsion), or 3rd (placental).
Stage 1st: It is the stage that starts with dilation of the opening of the cervix to 10 cm and contraction of the uterus.
Stage 2: in this stage fetus head moves to the cervix and gets into the birth canal of the mother.
stage 3. The placenta and umbilical cord expel from the mother and this is cut after the delivery.

2. Give one possible reason why the population decreased in 1990 after it had reached its
carrying capacity
1 I
Answer: The population exceeded its carrying capacity because there were more resources available so many deer reproduced and the population quickly exceeded the carrying capacity.
Explanation:
When the population size exceeds the carrying capacity, the population must decrease. One possible reason is the lack of available resources to support this population size.
What is Carrying Capacity?
A growing population that inhabits a limited space is gradually affected by density, rebounding in the multiplication rate.
The population growth per capita rate decreases as population size increases.
The population reaches a maximum point delimited by available resources, such as food or space. This point is known as the carrying capacity, K.
Carrying capacity refers to the maximum point at which the environment can support a growing population.
K is a constant. It coincides with the population size when natality rate and mortality rate are equal to each other. This is the equilibrium point.
If the population size, N, is inferior to K ⇒ the population still grow. When N approximates to K ⇒ the population's growth speed decreases. When N=K ⇒ the population reaches equilibrium, When N is superior to K (N>K) ⇒ the population must decrease in size because there are not enough resources to maintain that size.So when the population size exceeds K, carrying capacity makes the population decrease in size. This is because there are not enough resources for this population to survive.
Probably this population's size exceeded the carrying capacity because there were available resources and animals were not predated by any other species. So this population kept growing until they exceeded the carrying capacity level.
Once they did it, the environment could not support this population size, probably because of the lack of available resources, so the population had to decrease in size. Mortality rate must have increased while natality rate must have decreased.
One possible reason is the lack of available resources to sopport this population size.

Explain why spring tides are higher than all other tides.
Answer:
In both cases, the gravitational pull of the sun is 'added' to the gravitational pull of the moon on Earth, causing the oceans to bulge a bit more than usual. This means that high tides are higher and low tides are lower than average. These are called 'spring tides.
Explanation:
Fun facts:
Why are the spring tides the highest tides each month? Twice each month, the moon, sun, and Earth are aligned, so the pulling forces are combined to produce the highest and lowest tides, called spring tides.
Pilots use a simulation to learn to fly a plane. The simulation shows how
adjusting the controls on a plane under different atmospheric conditions
affects the flight. What type of model is this simulation?
O A. A computer model
B. A conceptual model
C. A mathematical model
O D. A physical model
Answer:

The difference between Prokaryotic cell and Eukaryotic cell are;
[tex]\begin{array}{lll}&\underline {\text {Prokaryotic}}& \underline {\text {Eukaryotic}}\\ \\ \text {Nuclear \ membrane \ and \ nucleus} & \text {No \ true \ nucleus \ or} & \text {Has \ a \ true \ nucleus} \\& \text {nuclear \ membrane} & \text {nucleoli \ and \ nuclear \ membrane}\\\\ \text {Membrane \ bound \ cell \ organelle} & \text {None &Present} \\\\ \text {Chromosome \ number \ and \ shape} & \text {One} & \text {Several, more \ than \ one} \end{array}[/tex]
Explanation:
Prokaryotic cells
The plasma membranes surround prokaryotic cells, however, within their cytoplasm, there are no organelles bound to the membrane and there is no nucleus in the prokaryotic cell which differentiates it from the eukaryotic cells
Eukaryotic cells
Eukaryotic cells also have plasma membranes, ribosomes and cytoplasm. Eukaryotic cells also have membrane-bound nucleus, membrane bound organelles, such as chloroplast, mitochondria, endoplasmic reticulum, and Golgi apparatus which together differentiates it from a prokaryotic cell
