Why did some people think that there was evidence of intelligent life on Mars?
Answer:
Recent missions to Mars haven't turned up definite proof of life, but some tantalizing possibilities have been uncovered.
Explanation: Water and ice caps if there's water there's life. but its not entirely true... because there isn't any life on mars... or so NASA says National Aeronautics and Space Administration more like Never a straight answer.
Many people believed that there was evidence of intelligent life on Mars, because of the similarities of this planet to planet Earth and because there are indications that there was water on Mars.
Although it is currently known that there is no intelligent life on Mars, many researchers believe that this planet has been inhabited in the past.
There is some evidence that allows this speculation to be established. Among this evidence, scientists claim that:
Mars has some characteristics similar to planet Earth.Many rocks on Mars have organic molecules.There is evidence that the surface of Mars once had water about two thousand years ago.There is water at the poles of Mars.There are water flows on the planet's hot slopes that are resistant to freezing.With this, we can see that, according to the evidence, it is not possible to affirm that there was already intelligent life on Mars, but that the planet has the possibility of having been populated by microorganisms.

wildlife monitoring technology is an important of protecting our ecosystems and the populations that live within them. How do you think advancements in the kind of technology could help protect burrowing owl populations.
Answer:
Plant more trees in areas that don’t have enough to make up for the loss of habitat. Also integrating large bird homes and sanctuaries around the power plants could help the owls settle back down in a semi-familiar environment.
Explanation:
Reduce threats to wildlife in the best remaining wilderness areas on Earth to keep their numbers stable or growing, to ensure sustainable fishing and hunting, and to settle disputes between people and wildlife.
What is the importance of wildlife monitoring technology?We can ensure that widespread species remain widespread and that unusual, threatened, and endangered species continue to get protection and aid thanks to data gathered through wildlife monitoring.
We may monitor pack dynamics, movements, ecological effects like feeding, mating, and nesting behaviors, illness outbreaks, snare incidents, and other human conflict issues through daily monitoring.
Therefore, We have a greater grasp of the occurrence, distribution, and status of animals in the preserves because of monitoring initiatives.

Once amylase has broken down starch, can it break down another starch molecule?
Answer:
Yes, amylase can be reused, and when fulfills its catalytic function, it is free to catalyze the breakdown of another starch molecule.
Explanation:
Amylase is an enzyme capable of catalyzing the breakdown of starch bonds, separating it into glucose molecules.
The enzymes, including amylase, have the property of being free and without structural alteration when catalyzing a reaction, to bind to the specific substrate and catalyze a new reaction.
Amylase is not consumed, unlike a reagent, so it can be reused in new reactions.
why is it called the water cycle
Answer: The water cycle is called the hydrologic cycle. In the hydrologic cycle, water from oceans, lakes, swamps, rivers, plants, and even you, can turn into water vapor.

Millimeters allow for the most accurate measurement.
Is cm extra accurate than mm?
A paper clip may be measured with both units (millimeter or centimeter) but a millimeter is the greater appropriate size to get an accurate measurement.
Why are millimeters more specific?A ruler marked in millimeters is extra unique than a ruler marked best in centimeters, considering a millimeter is a smaller unit than a centimeter.

A, C, E
Explanation:
If the beetles disappeared from this community, changes likely to occur include
an increase in the number of strangler figs, an increase in the population of fruit bats and decrease in the population of poison dart frogsThe beetles are insects which eat up strangler figs and a decrease mean an increase in its number.
The population of fruit bats will increase as they will have more strangler figs available for food.
Poison dart frogs will decrease because they feed primarily on beetles in the ecosystem.

Jamie notices some small objects floating at the bottom of a sample of pond water he collected. He is trying to decide if these objects are living. He drops a small amount of alcohol nearby, and the objects move in the opposite direction. What characteristic of living things is Jamie testing
Answer:
Irritability
Explanation:
Living things have been said to contain or possess certain characteristics that qualifies them to be "LIVING". These characteristics include; movement, respiration, growth, irritability, reproduction etc. The characteristics described in this question is IRRITABILITY.
IRRITABILITY is the ability of a living thing to respond to external or internal stimulus. In this case where Jamie drops a small amount of alcohol nearby a sample of pond water he collected, he notices that the small objects move towards the opposite side. This means that the objects are RESPONDING to a stimuli, which is the ALCOHOL in this case. Hence, irritability is the characteristics being tested.

Answer:
Show that life can only come from life (rather than spontaneous generation)
Explanation:
Pasteur boiled a broth in a flask with an S-shaped neck. Thebend in the neck prevented particles from the air reaching the broth, but still allowed air to get in. No bacteria grew in the flask.
When the flask neck was broken so that particles could get inside, the broth became cloudy, showing that microorganisms were only able to grow from other living things from the outside, and not spontaneously from nothing
Using the law of conservation of mass, what is the mass, in grams, of the product in the given reaction?
Reactant 1 (35 grams)+ Reactant 2 (115 grams) →Product (? grams)
A. 80
B. 140
C. 150
D. 75
Answer:
The correct option is;
C. 150
Explanation:
By the law of conservation of mass we have that in a closed system, the mass of the items in the system can not be destroyed or created by a physical process or chemical reaction
In the given chemical reaction process we have;
Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product = ((35 + 115) grams)
∴ Reactant 1 (35 grams) + Reactant 2 (115 grams) → Product (150 grams)
The mass of the product = 150 grams.
Humans often invade spaces that were once isolated, such as beaches, affecting how animals produce offspring. Humans are overtaking the natural habitat of sea turtles, reducing the space where they deposit their eggs. Females will only deposit eggs on the land where they were hatched, and if that is taken from them they will never lay eggs. Which is NOT a step humans can take in helping sea turtles? A) Respect the areas that have been roped off for turtle eggs B) When turtle eggs are found, move them to a safe place C) When boating, try to avoid places where turtles swim and eat D) If found, do not disturb eggs or sea turtles that are laying eggs
Answer:
B) When turtle eggs are found, move them to a safe place.
Explanation:
Based on the given article, we can learn that human encroachment has decreased the private lands/ spaces for animals to reproduce properly. One such case is that of the sea turtles. As the females only "deposit eggs on the land where they were hatched", it is important to keep them safe and undisturbed.
Therefore, one step that isn't helping the turtles is to move the eggs to a safe place. This is because female sea turtles "will never lay eggs" if their eggs are ever taken away from the original place they were laid at.
Thus, the correct answer is option B.
