Answer:
The blank is "apart."
Explanation:
Mid-ocean ridges are geologically important because they occur along the kind of plate boundary where a new ocean floor is created as the plates spread apart. Thus the mid-ocean ridge is also known as a "spreading center" or a "divergent plate boundary." The plates spread apart at rates of 1 cm to 20 cm per year.

Which of the following usually indicates stormy weather with clouds and precipitation?
A) Low humidity
B) Low air pressure
C) High air pressure
D) High humidity.
Low air pressure indicates stormy weather with clouds and precipitation. So, the correct option is (B).
How Clouds are formed?Clouds are formed by four processes. They are
1) Surface heating
In this process, the sun heats the earth and thus the air, this warm air rises, expands, and cools which forms the clouds.
2) Mountains and Terrains
Clouds also form when air meets mountains or other topography. The air rises and cools and, again, the air cannot hold all the water it holds when it warms so clouds form.
3) Air masses which are forced to rise and cool
Air is also forced to rise when air in a low pressure system forces air to rise.
4) Cold or warm weather fronts
Weather fronts cause cloud formation Clouds form because warm air rises above cold air and cold fronts form clouds because cold air displaces or lifts warm air.
Thus, Low air pressure indicates stormy weather with clouds and precipitation. So, the correct option is (B).

Lake Victoria in East Africa is home to many species of fish called cichlids. In 1954 the predatory Nile perch was introduced to Lake Victoria. The Nile perch became the dominant fish species in the lake by the mid-1980s. The number of cichlid species in the lake decreased as the Nile perch population increased. The perch preyed heavily on cichlid species that fed on algae and debris on the bottom of the lake. Algae in the lake increased, and oxygen levels decreased. The surface area of the gills of some cichlid species has increased in just over 20 years. Which statement explains the increase in gill surface area seen in some of Lake Victoria’s cichlids? Increased gill surface area has allowed the cichlids to change their diet and avoid competing with the Nile perch. Increased gill surface area has allowed the cichlids to be camouflaged and avoid being eaten by the Nile perch. Increased gill surface area has allowed the cichlids to leave Lake Victoria and establish populations in nearby bodies of water. Increased gill surface area has allowed the cichlids to better absorb the limited oxygen in the water.
The statement that explains the increase in gill surface area seen in some of Lake Victoria’s cichlids is that increased gill surface area has allowed the cichlids to better absorb the limited oxygen in the water. The correct option is D.
What are species?The greatest group of organisms in which any two individuals of the right sexes or mating types can result in fertile offspring is commonly referred to as a species.
An organism of a particular species. It serves as both a formal rank in taxonomy and a fundamental unit of biological classification.
The word's first informal usage was rather ambiguous, but there are currently at least 26 alternative ways to use it. The same species includes all members of the same sort of animals or plants.
Therefore, the correct option is D, increased gill surface area has allowed the cichlids to better absorb the limited oxygen in the water.

What caused the surface of the moon to look the way it does?
Answer:
Depends
Explanation:
If you mean from down here on Earth point of view, then it is sunlight reflecting off of its surface. If you mean on the moon point of view, then it is because the moon has impact craters and dead volcanoes all over it.
The surface of the moon to look the way it does because on Earth point of view, then it is sunlight reflecting off of its surface. If you mean on the moon point of view, then it is because the moon has impact craters and dead volcanoes all over it.
What are volcanoes?A volcano has a hill or mountain or it has an opening in a planet or moon's crust from which molten rock, warm gases, and materials erupt. It has a landform where molten rocks erupt through the surface of the planet and volcano moutains open downwards to molten rocks.
According to Geologists there's are four types of the volcanoes and these are lava domes, shield volcanoes, composite volcanoes, and cinder cones.
The main reason behind the formation of volcanoes are movement of tectonic plates it means when one tectonic plate moves under another tectonic plate volcano has been formed.

A weather forecast shows that it is humid and warm today, and the temperature is expected to cool off later. How will this affect the weather?
A) Air pressure will decrease.
B) Clouds and rain will form.
C) The weather will be sunny with a clear sky.
D) The weather will remain humid and warm.
Clouds and rain will form will be the resulting effect of the mentioned weather which is humid and warm.Therefore, the correct option is B.
What is humidity?Humidity is a measure of the amount of moisture or water vapor present in the air. Specifically, humidity refers to the amount of water vapor present in the air compared to the maximum amount that the air could hold at a given temperature.
When the air is warm and humid, it can hold a lot of moisture. However, as the temperature drops, the air's ability to hold moisture decreases, and the excess moisture may condense into clouds and eventually fall as precipitation (rain or snow). Therefore, a forecast of warm and humid conditions followed by cooler temperatures suggests that clouds and rain are likely to form.Therefore, the correct option is B.

3. This living sea star and tossi sea urchin both have body structures that paris
are formed along five lines. What best explains why both species have this
five-lined body structure?"
sea star
fossil sea urchin
The sea star and sea urchin are different species, so they must not share an ancestor
population. They must have inherited this five-lined body structure from separate
ancestor populations
The sea star and sea urchin both share the same ancestor population that had a five
lined body structure. They inherited this structure from the ancestor population
It is impossible to say, Fossils are very old; therefore, we cannot make observations of
the sea urchin's ancestors, and we cannot explain its body structure,
All species have their own specific body structures, so it is a coincidence that this sea
star and sea urchin each have this specific type of five-lined body structure,

I need help with this!! Questions are in the picture!! Feel free to only do 1 or 2 questions!! Doing all is really really appreciated tho!!
Answer:
9. D (100%)
10. C (Round and Wrinkled)
11. C (75%)
12. B (25%)
Explanation:
9. 100% will be brown, because brown (B) is dominant. That means that if all squares have Bb or BB once you fil out the punnett square, then the offspring would have to show the dominant trait. In this example, all possibilities for the organism were Bb, so brown.
10. Rr and rr are being crossed in this example. Heterozygous is Rr, Wrinkled is rr and Round is RR or Rr. The answer id Round and Wrinkled because one parent is Rr (round) and the other is rr (wrinkled).
11. Yellow seeds are dominant, so any box that has at least one Y will be dominant. 3 of the 4 boxed have a Y, therefore there is a 75% chance the offspring will be yellow.
12. Long hair is not the dominant trait, it is recessive. This means any box WITHOUT a capital S will be recessive. There will be one box, the lower left box. It will be ss. Since one out of four are ss, that means there is a 25% chance the guinea pig will have long hair.

Which best describes when the body is working on counteracting an effect?
when hormone levels in the body are all equal
during a negative feedback loop
during a positive feedback loop
when the hypothalamus is signaling the pituitary gland
The answer is a negative feedback loop. Negative feedback is used to counteract an effect and achieve back a homeostatic balance. An example of a negative feedback loop is in thermoregulation. When temperatures are too high, the hypothalamus induces body responses such as vasodilation and sweating that enable the loss of excess heat.
