Unlike animals, plants make the own food out of water, at, and sunlight Plants need water just as we do, they also use water to make
their food. The part of the ar that plants use is called carbon dioxide. When plants make food they take carbon dioxide out of the air and put
Green Into the origen is the part of the ar that we need to breathe The energy that all living things get from eating food comes from the sun
A piant cantike this solar energy directy and use it to make food for itself. When we eat plants, we are getting energy that the plant got from the
sun and then made into food
What does the word solar mean in this paragraph?
To understand what it means you should find the paragraph where this word is "solar energy". This is the energy that plant absorb. Solar means from sun

Which statement is FALSE? A. Phototropism and geotropism are adaptations of plants that allow for survival. B. Tropism is the growth response of plants to their environment due to external stimuli. C. A plant's response to moonlight is phototropism while it's response to gravity is geotropism. D. A tropism that causes a plant to grow towards the stimulus is positive.
Answer:
A. Phototropism and geotropism are adaptations of plants that allow for survival.
Explanation:
Ideally, TROPISM is the growth response of plants to their environment due to external stimuli as rightly stated in this question. However, based on what stimulus the plant is responding to, there are different types of stimulus.
Phototropism (photo-light) is the response of an organism to a light source while Geotropism (geo- gravity) is the response of an organism to gravity. Hence, based on this question, a plant's response to moonlight is phototropism while it's response to gravity is geotropism.
Also, tropism can either be positive or negative depending on whether the response is towards the stimulus (positive) or away from the stimulus (negative). Therefore, the FALSE statement is "Phototropism and geotropism are adaptations of plants that allow for survival"
What organic molecules can be found in protein, oxygen, and fat?
Answer:
Lipids are organic compounds that consist of carbon, hydrogen, and oxygen. They are made up of fatty acids and other compounds. They provide cells with energy, store energy, and help form cell membranes. Proteins are organic compounds that consist of carbon, hydrogen, oxygen, nitrogen, and, in some cases, sulfur.

Why do gymnosperms and lower vascular plants lack companion cells?
Answer:
Gymnosperms and lower vascular plants have sieve cells as their sieve elements, while sieve tubes are characteristic of flowering plants angiosperms. In gymnosperms, typical companion cells are lacking in the phloem. In gymnosperms, generally the xylem contains only tracheids. Vessels are absent.

which of the following levels of organization best represents the sequence from smallest unit to largest
Answer:
D.
Explanation:
In the sequences given, cell is the smallest unit and organ system is the largest unit.
The levels of organization the best represents the sequence from smallest to largest units is cell, tissue, organ, and organ system.
The cell represents the smallest and basic unit of all living organisms.Tissues are aggregates of cells performing similar functions.Organs are made of different similar tissuesOrgan systems are a collection of different organs coming together as a system to perform specific functions. Examples include the respiratory system which is made up of organs like lungs, windpipe, nose, mouth, etc.More on different levels of organization of living organisms can be found here: https://brainly.com/question/6033339?referrer=searchResults

Which structure pumps out excess water and wastes?
Answer:
The contractile vacuole pumps out excess water and wastes.
Cells have a particular organelle that pumps out excess water and other wastes from the cell. Contractile vacuole serves this purpose.
The protozoan cell contains an organelle or subcellular structure called the Contractile Vacuole. It is a spherical, transparent, translucent, pulsating single-cell organelle. Previously, it was referred to as a pulsatile or pulsating vacuole. It is encased in a unit membrane, floats in the cytoplasm, and is filled with watery fluid. It is a vacuole that constricts and expels water from the cell, as its name suggests. It frequently stretches and shrinks. While water is expelled from the contractile vacuole as it expands, the contractile vacuole contracts, causing water to collect inside the organelle. The contractile vacuole is the protozoan unicellular organism's kidney. It shows the rhythmic systolic and diastolic movements.
Therefore, Contractile vacuole pumps out excess water & wastes.

The amount of kinetic energy an object has depends on which feature of the object?
O its motion
O its position
its gravity
O its height
Answer:
A. Motion......
The amount of kinetic energy an object has depends on its motion.
WHAT IS KINETIC ENERGY?Kinetic energy is the energy of an object that is due to its motion.
The kinetic energy of an object is denoted by the following expression:
K.E = ½ × mass × velocity.Therefore, this shows that amount of kinetic energy an object has depends on the motion of the object.

Identify the statement below that is NOT a principle of evolution.
O Populations evolve, individuals do not
O Negative adaptations will become more common in a population
O Variations occur naturally within a population
O Adaptations help individuals compete successfully for survival
B) negative adaptations will become more common in a population
negative adaptations will become more common in a population.
What is Evolution?According to the idea of evolution in biology, the many species of plants, animals, and other living things on Earth descended from earlier species, and their recognizable differences are the result of changes made by subsequent generations.
More than 2 million species of organisms already in existence have been recognized and documented; many more are still undiscovered, with estimates ranging from 10 million to 30 million.
The amazing variability in size, form, and mode of existence, from tiny bacteria with a diameter of less than a millionth of a millimeter to majestic sequoias with a height of 100 meters, is as astonishing as the figures.
Therefore, negative adaptations will become more common in a population.
