Answer:
0.25 m/ hour
Explanation:
A rate of movement is essentially a speed measurement, where you divide the distance crossed from point A to point B by the time it took to do it.
So, we know the snail moved a total distance of 0.5 meters... that's our distance crossed.
We know that took 2 hours... so we just have to calculate that:
0.5 meters / 2 hours = 0.25 m/hour
Answer:
The answer is Velocity is equal to 0.25 meter per hour.
Explanation:
Velocity is the physical magnitude of a vector character that relates the change of position with time. The velocity shows and expresses the variation in terms of the position of an object and as a function of time, which would be the same as saying that it is the distance traveled by an object in the unit of time.
Velocity is expressed with the formula [tex]v = \frac{d}{t}[/tex] where (v) represents velocity, (d) represents distance and (t) represents time.
knowing this we can proceed to replace the values given in the problem.
[tex]v = \frac{0.5m}{2h}\\ v= 0.25\frac{m}{h}[/tex]

Clouds form when water vapor in the atmosphere cools to _______.
a) its dew point
b) its relative humidity
c) its convection point
d) its precipitation
Answer:
A
Explanation:
Answer:
The answer to the question: Clouds form when water vapor in the atmosphere cools to:____, would be, A: Its dew point.
Explanation:
Clouds are simply the visible condensation of the warm air that rises into the cooler atmosphere. Once this happens, with the moisture carried in the warm air, the cooler atmosphere will bring down the temperature of the air, and the water inside it in form of vapor, till it reaches dew point. Once there, the air condenses into either water dropplets, or crystals, making clouds look like formed pieces of cotton. If condensation is light, the clouds will appear white, and clear, as condensation gets higher, and temperatures change, the cloud will get darker, as it gets heavier with water. At its breaking point, water will come down now condensed either as rain, or ice, depending on temperatures.

The primary function of the human digestive system is to break down food into smaller molecules so they can be absorbed into the bloodstream and supplied to the body's cells. Food undergoes both mechanical and chemical digestion in the stomach and intestines, leading to absorption of nutrients.
Explanation:The main function of the human digestive system is B) process organic molecules so they can enter cells. The digestive system begins this process in the mouth where food is broken down mechanically by teeth and chemically by salivary enzymes.
It continues in the stomach where gastric juices break down proteins. After that, in the small intestine, enzymes from the pancreas further break down food, allowing nutrient molecules including carbohydrates, proteins, and fats to be absorbed into the bloodstream.
The digestive system finishes this process in the large intestine, where water and electrolytes are reabsorbed back into the system, essentially leaving waste material that is then excreted via the rectum and anus. Therefore, the principal job of the digestive system is to break down food into tiny molecules and deliver them into the cells to be used as fuel for energy, growth, and cell repair.

Protozoan infection definition
Protozoan infections are parasitic diseases caused by organisms formerly classified in the Kingdom Protozoa. They include organisms classified in Amoebozoa, Excavata, and Chromalveolata. Examples include Entamoeba histolytica, Plasmodium (some of which cause malaria), and Giardia lamblia.
A protozoan infection is caused by single-celled organisms called protozoa, which can be transmitted via vectors, contaminated food or water, or sexual contact. They often exist in a dormant cyst form outside the host and activate into trophozoites once inside. Examples include Giardia and Plasmodium species.
A protozoan infection is caused by protozoa, which are single-celled, animal-like organisms that belong to the kingdom Protista. These infections can be transmitted through various means such as vectors (insects or arthropods), contaminated food or water, or sexual contact. Protozoa often exist in a dormant stage called a cyst, allowing them to survive outside a host and facilitating their transmission.
Once inside the host, protozoa transition into their metabolically active form known as trophozoites, which feeds and multiplies. Common examples of protozoan pathogens include Giardia and Plasmodium species, which can cause serious health issues such as gastrointestinal illnesses and malaria, respectively. Diagnosis often involves microscopic examination of stool or biopsy specimens.
What do euglenoids lack? cell walls chloroplasts contractile vacuoles eyespots
Answer:
Euglenoids lack a Cell wall
Explanation:
Euglena is a unicellular photosynthetic protista that can be found in both salt water and fresh water. As Euglena has chloroplasts they can produce their own food through photosynthesis. For their movement in water they have specialized structure called flagella. Near Flagella another pigmented spot exist called eyespot. Eyespot helps euglena to detect sunlight. Euglenoids lack cell wall so they have more flexibility for movement.

C) Atoms lose energy as a solid changes to a liquid.
D) Atoms lose energy as a solid changes to a gas.
I believe the answer is c
Answer: A) Atoms gain energy as a solid changes to a liquid.
Explanation: Atoms in liquid possess more energy than the atoms in solid. The change of state from a solid state to a liquid state is called melting. Energy is applied to the molecules in solid state the molecules begin to move quicker and begins to break away from the other molecules. The heat absorbed leads to the molecules to moving farther apart from others thereby overcoming the intermolecular forces of attraction between them.
The solid state gains energy in form of heat as solids converts to liquid.

Explanation:
What's the role of a primary consumer in the food web?
Answer:
To make energy available for transfer to higher trophic levels.
Explanation:
Primary consumers are the organisms that feed directly on the autotrophs to obtain energy. These consumers thus help to transfer energy to higher trophic levels that are secondary consumers.An example is the goat feeding on a plant is a primary consumer that directly obtains its energy from the plant. However, by feeding on the plant, it makes energy available for the secondary consumer, which in this case would be a lion.The role of a primary consumer in the food web is to transfer energy within an ecosystem through scouting and consuming of foods which are beneficial to them, and are subsequently consumed by other consumers i.e. secondary and tertiary consumers which are termed as carnivores and omnivores.
Further ExplanationThe significant role of primary consumers in the food web helps keep balance of an ecosystem or a community from collapsing.
A typical primary consumer eats plants and grasses. Primary consumers are mostly herbivores. Primary consumers are located in the bottom level of animals in the food web.
The food web refers to the natural feeding relationship that exists in an ecosystem or a community. Food web comprises of food chains that are interconnected. Aside the primary consumers being in the food chain, secondary and tertiary consumers are also in the food chain.
It should be noted that without the important role of primary consumers, secondary and tertiary consumers would severely be short of much needed energy and nutrients, since they cannot produce their own food.
Therefore, primary consumers play a significant role through the transfer of energy as a result of consuming primary producers i.e. plants which make use of sunlight (solar energy) to provide their own food through the photosynthesis process.
And since plants are consumed by primary consumers, energy derived from the sun is transferred to them, and are tend to be transferred to whichever consumer that consumes the primary consumer.

Final answer:
The inner planets are dense and rocky due to the high temperatures near the Sun which caused lighter materials to evaporate, leaving behind rocks and metals. The outer planets are large and gaseous because they formed in cooler regions where it was possible for gases and ices to condense around a dense core. The solar system also contains asteroids, comets, and the asteroid and Kuiper belts, showing a transition in composition.
Explanation:
Why Inner Planets are Dense and Rocky While Outer Planets are Gaseous
Our solar system is divided into two distinct types of planets: the inner planets (Mercury, Venus, Earth, and Mars) which are dense and rocky, and the outer planets (Jupiter, Saturn, Uranus, and Neptune) which are large and composed mostly of gases. This division is largely due to the heat of the Sun and the distance of the planets from the Sun during the formation of the solar system.
Formation of Inner and Outer Planets
The inner planets formed in a part of the solar system where temperatures were high due to the proximity to the Sun. This heat caused lighter materials, such as water, carbon dioxide, methane, and ammonia, to remain in gas phase or evaporate if they were present on the forming planets, leaving behind dense, rocky materials. As a result, the inner planets are composed primarily of rocks and metals which could withstand the high temperatures.
In contrast, the outer planets formed in cooler regions of the solar system, where it was cold enough for gases and ices to condense. These planets started with a dense core similar to the inner planets but were able to accumulate large amounts of light gases like hydrogen and helium from the solar nebula. This accumulation of gases around their cores is why the outer planets are much larger and have a gaseous composition.
Other Objects in Our Solar System
Beyond the planets, our solar system is also home to asteroids, comets, the asteroid belt located between Mars and Jupiter, and the Kuiper Belt and Oort Cloud which contain many icy bodies. These objects represent a transition in composition from the rocky materials of the inner solar system to the icy constituents of the outer solar system.
