Answer:
The correct answer is "pollinator".
Explanation:
Insects are the first animals that come to mind when we think about pollinators, however hummingbirds are an excellent example of pollinators as well. Hummingbirds feed frequently from flowers, transferring grains of pollens from a flower to others. Some species of flowers have adapted to develop some traits to attract hummingbirds, such as certain color, shape and scent.

The production and transmission of hormones in the endocrine system is MOST similar to which scenario?
Answer:
You type a text message, which your friend shows to a third party, who reacts to it.
Explanation:
Copied from google.
When a message is shown to a friend who shows it to another person.
What is the endocrine system?
A group of organs called glands makes up your endocrine system. These glands, which may be found all over your body, produce and emit hormones.
Hormones are substances that communicate with your organs, skin, muscles, and other tissues through your blood to coordinate various bodily activities. These messages instruct your body on what to do and when.
The level of hormones in your blood is regularly monitored by your endocrine system. In order to transmit the message, hormones send their messages by locking them into the cells they intend to reach.
When your hormone levels increase, the pituitary gland signals other glands to stop manufacturing and releasing hormones. The pituitary gland has the ability to tell other glands to manufacture and release additional hormones when levels fall below a specific threshold. Homeostasis is a mechanism that functions similarly to your home's thermostat. Almost every process in your body is impacted by hormones.
Therefore, it is like the scenario where a message is shown to a friend who shows it to another person.

Evan finds a rock. He scrapes it with his fingernail and leaves a scratch. His rock must be:
O a metamorphic rock
harder than feldspar
softer than diamond
made of more than one mineral
HELLP
The correct answer is C. Softer than diamond
Explanation:
Evan observation is related to the rock's hardness, which is usually measured on a scale from 1 to 10, in which 10 represents the hardest rock (diamond). In the case of the rock Evan found, the fact the rock can be scratched just using a fingernail shows the hardness of this rock is 2.5 or below because only minerals with this hardness can be scratched using the fingernail, while a higher hardness requires more complex tools.
Moreover, in this level of hardness, there are minerals such as gypsum or talc and these are softer than others such as feldspar with a hardness of 6 or diamond with a hardness of 10. In this context, it is safe to conclude this rock is softer than diamond. Also, hardness is not enough to determine if a rock contains two or more minerals or if it is metamorphic.
Why is the earth's gravity stronger than the moon's gravity? A:The moon is so far away from earth. B:The earth is more massive than the moon C:The moon has no mass. D:The earth has a larger volume than the moon.
Answer:
A and B
Explanation:
Gravity relies on both mass and distance
The reason the earth's gravity stronger than the moon's gravity is B. The earth is more massive than the moon
How is the earth gravity stronger ?Gravity is a force that attracts two objects with mass towards each other. The more mass an object has, the stronger its gravitational pull.
The distance between two objects also affects the strength of gravity. However, the distance between the Earth and the Moon is not large enough to significantly weaken the Earth's gravitational pull.
The Earth has a mass of about 5.972 × 10^24 kilograms, while the Moon has a mass of about 7.347 × 10^22 kilograms. This means that the Earth's gravity is about 6 times stronger than the Moon's gravity.

A scientist wants to test whether the pH, salinity, or temperature of seawater impacts coral
development. He sets up an experiment with three conditions:
Aquarium 1: Normal pH, normal salinity, normal temperature
Aquarium 2: High pH, high salinity, high temperature
Aquarium 3: Low pH, low salinity, low temperature
What factor would improve experimental design the most?
Eliminating Aquarium 1 since it only uses normal conditions
Testing one variable at a time and keeping the other two variables constant
Using one aquarium and changing the variables from day to day
Setting up the variables on a gradient in each aquarium
Answer: Testing one variable at a time and keeping the other two variables constant

11- El Pirata Barba Plata ha llegado a la isla del Coral para buscar un
tesoro. En el mapa pone que, desde la orilla, debe recorrer 3,7 hm a la
pata coja hacia el centro de la isla, y después otros 8,5 dam dando
volteretas en la misma dirección. ¿Cuántos metros recorrerá en total
desde la orilla hasta el tesoro? * cuál es la repuesta
Answer:
El pirata recorrerá 455 metros
Explanation:
3,7 hectómetros (hm) = 370 metros (m)
8,5 decámetros (dam) = 85 metros (m)
>> Distancia en metros = 370 m + 85 m = 455 metros
El hectómetro (hm) es una unidad de longitud que equivale a 100 metros, donde el prefijo hecto indica la equivalencia a 100 metros. Por su parte, el decámetro (dam) equivale a 10 metros, donde el prefijo deca indica la equivalencia a 10 metros.
In our neighborhoods we have garbage people that come around and
collect garbage and waste at you home. What does that inside of the cell.
Answer:
The answer is lysosomes
Explanation:
Lysosomes are membrane bound organelles that contain degradative/digestive enzymes which are used to digest/degrade/break down unwanted or worn out cellular organelles through a process known as autophagy.
The reason the answer is lysosomes is because the waste (unwanted or worn out organelles) use to be a useful part of the home (cell), however, there is another organelle responsible for absorbing and neutralizing toxins in the cell; it's called peroxisomes

Which atom has two unpaired electrons in the outer valence
shell?
O helium
hydrogen
Oxygen
Olithium
Answer:
Oxygen
Explanation:
The electrons present in an atom are arranged in shells or orbitals. The electrons are filled into these shells based on their energy levels with those shells closest to the nucleus filled first as they have the lowest energies.
The arrangement of electrons around the nucleus of an atom is known as electronic configuration. The outermost electron shell of an atom is known as a valence shell shell and the electrons found in this shell are known as valence electrons. The electrons usually exist in pairs. The first shell can only contain two electrons; the second shell can contain 8. the electrons are singly filled first before pairing occurs.
The electronic configuration of the atoms of the elements in the option are as follows:
Helium : 1s² ; valence electrons are 2 which are both paired
Hydrogen: 1s¹ ; valence electron is 1
Oxygen : 1s²2s²2p⁴ ; valence electrons are 6 wit two unpaired electrons
Lithium : 1s²2s¹ ; valence electron is 1
Helium has two valence electrons but they are paired as its 1s shell can only contain a maximum of two electrons.
Oxygen has 6 valence electrons. Two of these electrons are paired while the other two are unpaired.

Describe the type and ratio of organisms you would expect to find in a lake in a national park. give evidence to support your answer
Answer:
Algae would be the organism in greatest proportion in a lake in a national park.
Explanation:
A lake in a national park would have algae proliferation, which would be the largest organism in that lake. This is because a lake in a national park is subjected to great incidence of sunlight and large amounts of oxygen. This would facilitate and stimulate the reproduction of algae on a large scale, causing them to develop in the substrate, stones, pebbles, and in the water itself.
