There are many reasons for this. First of all, any water from Earth's surface can flow into the ocean due to gravity. There are also glaciers in the ocean that can melt. In the water cycle, the ocean, the atmosphere, and the land continuously exchange moisture among each other. Because weather patterns form and dissipate slower over the water than over the land, there is more circulation occurring in the atmosphere above the land. Therefore, there's more cloud formation.
Precipitation is less common on land than over the oceans primarily because a larger volume of water vapor is generated over the oceans. This is due to the vast ocean surfaces which facilitate evaporation. Since most evaporated water precipitates back into the oceans, less is available to be transported over land.
The water cycle describes the continuous movement of water on, above, and below the surface of the Earth, where it changes states among liquid, vapor, and ice. The oceans, which hold over one billion cubic kilometers of water, are the main source of evaporation due to the large surface area and abundant solar heat. About 400 thousand cubic kilometers of water vapor are produced from the oceans annually, but most of it falls back as precipitation over the ocean itself. Only about 40 thousand cubic kilometers are transported as atmospheric moisture from the oceans to land, where it adds to the 70 thousand cubic kilometers of recycled water from evapotranspiration on land. Consequently, the lesser amount of water vapor available over land compared to over the oceans results in less precipitation.
Which of the following is not a characteristic shared by all chordates?
fins
hollow nerve chord
pharyngeal pouches
notochord
Fins
Fins are not a characteristic of all chordates
Explanation;All Chordates share four key features, which includes; a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post tail.The notochord provides skeletal support, gives the phylum its name, and develops into the vertebral column in vertebrates. The dorsal hollow nerve cord develops into the central nervous system: the brain and spine. Pharyngeal slits are openings in the pharynx that develop into gill arches in bony fish and into the jaw and inner ear in terrestrial animals. The post tail is a skeletal extension of the posterior end of the body, being absent in humans and apes, although present during embryonic development.The characteristic that is not shared by all chordates is 'fins'. While fins are seen in certain subgroups of chordates, not all chordates possess them. The three main features common to all chordates are a hollow nerve chord, pharyngeal pouches, and a notochord.
Explanation:The characteristic that is not shared by all chordates is fins. The chordates, which include vertebrates, have three main defining features: a hollow nerve chord, pharyngeal pouches, and a notochord. However, not all chordates have fins. For instance, chordates like mammals and birds do not possess fins, but they do have the other three common features.
Fins are typically seen in aquatic or semi-aquatic species such as fish, but they are not a necessity for all chordates. Fins are used for movement, balance, and steering in an aquatic environment, but they are not a feature shared universally by chordates. Thus, while fins are common in certain subgroups of chordates, they are not a characteristic shared by all.

A biology student is investigating tropisms in plants. The student observes the response of the roots of radish seedlings to a light source placed to the right of the roots. All of the roots grow away from the light source. Which of the following tropisms is the student MOST LIKELY investigating?
gravitropism
thigmotropism
hydrotropism
phototropism
Answer:
phototropism
Explanation:
The student was investigating phototropism.
The student wanted to know the response of the roots to light, that is why he exposed them to light.
Roots naturally exhibit two types of tropisms.
The first is gravitropism whereby they tend to grow downwards.
The second is hydrotropism whereby they grow towards the direction of water.
In the above experiment, no water was provided, the roots grew away from the light source but not specifically downwards.

Explanation:
Placing an object in a known amount of water, the quantity of the water that rises helps you find the volume by ____.
The volume of an object submerged in water can be determined by how much water it displaces, also known as the water displacement method. This principle is often used in physics to measure the volume of irregularly shaped objects.
Explanation:Placing an object in a known amount of water, the quantity of the water that rises helps you find the volume by displacing the water. This method, known as the water displacement method, is often used in physics to determine the volume of an irregularly shaped object.
To use this method, you place the object in a graduated cylinder partially filled with water. The water level rises when you insert the object since it displaces its own volume of water. The increase in water level corresponds to the volume of the object. This is based on the fundamental principle that the volume of liquid displaced when an object is submerged in it, equals the volume of the object that is submerged.

Evolution takes a very long time and so the genes won't be completely different
What is an ADVANTAGE of sexual reproduction?
A) Two parents are required
B) One parent is required
C) It leads to genetically diverse offspring
D) It leads to genetically identical offspring
C) It leads to genetically diverse offspring is your answer.
Genetic diversity allows the passing down of traits that are likely to increase chances of survival, such as immunity to certain diseases. However, genetic diversity cannot be confused with evolution, as evolution can only lead to deterioration of the being, rather then adaptability & survivability.

If a rifleman's gunsight is adjusted incorrectly, he might shoot bullets consistently close to 2 feet left of the bull's-eye target. draw a sketch of the target with the bullet holes. does this show lack of precision or bias?
b. draw a second sketch of the target if the shots are both unbiased and precise (have little variation). the rifleman's aim is not perfect, so your sketches should show more than one bullethole.
Not going to draw it since i'm horrible at drawing but it's pretty simple. The shots that are consistently 2 feet left means his aim is fine but his sites are off. It shows no lack of precision.
The second one is pretty simple aswell. every rifleman can't shoot the same hole every single shot. Many things affect it but the same technique the same time for every shot with "zero'd" sights means the rounds should be inpacting within a relativly small shot group.

which of these is an example of climate?
A. last month's total rainfall
B. a weather forecast
C. the current temperature
D. An annual weather pattern
The answer to the question is D. An annual weather pattern.
The question, "Which of these is an example of climate?" involves understanding the difference between climate and weather. Climate refers to the long-term, predictable atmospheric conditions of a specific area, while weather pertains to atmospheric conditions over a short period. Therefore, the correct answer is D. An annual weather pattern, as it encompasses the long-term averages of weather in a specific location, which is indicative of climate. Last month's total rainfall or a specific day's temperature are examples of weather events, not climate. Similarly, a weather forecast predicts short-term atmospheric conditions and is also not an example of climate.

Which of the following muscles is voluntary
muscles in your arm, give brainliest if right
Voluntary muscles, such as skeletal muscles, are those that can be consciously controlled by an individual. Cardiac muscles, which are often mistakenly thought to be voluntary, are actually involuntary and operate automatically. Skeletal muscle movement includes both conscious actions and involuntary reflexes.
Explanation:Understanding Voluntary MusclesThe muscles that can be controlled by an individual's will are known as voluntary muscles. An example of a voluntary muscle is the skeletal muscle, which is attached to the skeleton and enables movement of the body. These muscles are under conscious control, meaning that we can decide when to move them. For instance, you can choose to lift your hand or walk. However, skeletal muscles can also contract involuntarily in response to reflex actions, such as withdrawing your hand when you touch something hot.
It's important to correct a common misconception: while cardiac muscles, found in the heart, are also muscle tissue, they are not voluntary but rather involuntary muscles which cannot be consciously controlled.
Involuntary muscles, including both cardiac and smooth muscles, operate automatically without conscious thought. They perform critical functions like pumping blood through the heart and moving food through the digestive system.

How are microtubules thought to affect cell shape in plants? Microtubules of the plant cell cortex are thought to affect the movement of cellulose-synthesizing enzymes in the cell membrane, which, in turn, affect cell wall growth and shape. Microtubules of the plant cell vacuole are thought to affect the movement of cellulose-synthesizing enzymes in the cell membrane, which, in turn, affect cell wall growth and shape. Microtubules of the plant cell cortex are thought to affect the movement of lipid-synthesizing enzymes in the cell membrane, which, in turn, affect cell wall growth and shape. Microtubules of the plant cell wall are thought to affect the movement of cellulose-synthesizing enzymes in the cell membrane, which, in turn, affect cell wall growth and shape. 5. Microtubules of the plant cell nucleus are thought to affect the movement of cellulose-synthesizing enzymes in the cell membrane, which, in turn, affect cell wall growth and shape.
The correct answer is: Microtubules of the plant cell cortex are thought to affect the movement of cellulose-synthesizing enzymes in the cell membrane, which, in turn, affect cell wall growth and shape.
Plants have the ability to control the direction of cell expansion as a way of shaping growth. Microtubules are structures that help them to regulate the direction of growth. For example, transverse microtubules within the plant cell have the role to constrain the movement of cellulose synthase complexes that are essential for elongation growth.

which of the following particles is the fundamental unit of all matter, both living and nonliving ?
a)neuron
b)electron
c)atom
d)cell
Answer:
c)atom
Hope this answer correct :)
The fundamental unit of all matter is the atom, consisting of protons, neutrons, and electrons. Cells are the smallest units of life but not the fundamental unit of all matter. Electrons are fundamental subatomic particles known as leptons.
The fundamental unit of all matter, both living and nonliving, is the atom. Atoms are the basic building blocks of matter and consist of three main components: protons (positively charged), neutrons (neutral charge), and electrons (negatively charged). While cells are the basic building blocks of life, it is atoms that make up cells and everything else in the universe. Protons and neutrons form the atom's nucleus, which has a positive charge because of the protons. The electrons move around this nucleus in the electron cloud, attracted by the positive charge.
It's important to note that while cells are indeed the smallest independently functioning biological units in an organism, they are not the fundamental unit of all matter. Additionally, the electron is an example of a fundamental subatomic particle, specifically a lepton, which is different from the composite particles like neutrons that contain quarks.
