Which one is not needed ?
Answer:
Space
Explanation:
Answer:
Well... I would say it is gravity that is not needed.
Explanation:
In the picture at the top it says "we need to breathe air and live in some type of space. If these requirements are lacking, life ceases to exist."
Thus, stating that air, space, energy, and water are needed for life to exist. That leaves out gravity. Gravity is not needed for life to exist because, for example, humans and other living organisms are already living in outer space without the need for gravity.
Hope that helps!! :-)

why does the bimetallic strips bend when it been heated
Answer:
The bimetallic strip is made of two metal strips, stuck together. One of the metals expands much more than the other when they are heated. This causes the strip to bend.

Which of the following equations correctly summarizes the process of
photosynthesis?
Answer:
H2O+CO2 LIGHT sugars+O2
Explanation:
The equation (Carbon dioxide + water ⇒ Glucose + Oxygen) summarizes the process of photosynthesis correctly, as glucose is formed along with oxygen in photosynthesis. Thus, the correct option is A.
What is Photosynthesis?
Photosynthesis is the process of formation of carbohydrate (sugar) in the leaves of green plants. In this process, the solar energy from the sun is converted into chemical energy in the form of sugar. Here, the sunlight is trapped in the chlorophyll pigment present in the chloroplast.
The sunlight with chlorophyll converts carbon dioxide and water into glucose and oxygen, the glucose is used to produce energy through Cellular respiration and oxygen is used in the process of respiration.
Therefore, the correct option is A.

_____ pressure is what gives plants that are not woody their rigid structures.
Hypertonic
Hypotonic
Turgor
Turgid
Isotonic
Answer:
I'd say C.)
Explanation:
Turgor pressure, also called turgidity when occurring in trees and most plants are the pressure of cell contents exerted against the plant cell wall including tree leaf and stem cells. ... This force consequently gives a succulent plant rigidity and helps non-woody plants to keep erect.
why are cells considered the most basic unit of life
Answer:
Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages.
Explanation:
That's because all cells are surrounded by a structure called the cell membrane — which, much like the walls of a house, serves as a clear boundary between the cell's internal and external environments.
Hope this helps :)

The James-Lange theory of emotion is different from the Cannon-Bard and
Schachter-Singer theories in that it:
A. does not acknowledge the importance of the body.
B. says the brain and body are both important.
ОО
C. says the thalamus routes the signals.
D. does not acknowledge the limbic system.
A. does not acknowledge the importance of the body.
What is James-Lange theory?The James-Lange theory is a psychological theory of emotion that argues that emotions arise from physiological reactions to events in the environment.
According to the theory, emotions are not inherent or innate, but rather are learned through experiences with external stimuli. The theory proposes that when a person experiences an event, their body reacts with physical arousal, and it is this physical arousal that then gives rise to the subjective experience of emotion. For example, if someone is scared, their heart rate will increase, and it is the physical arousal caused by this increase in heart rate that produces the feeling of fear. The James-Lange theory has largely been discredited, but it continues to influence contemporary theories of emotion and to inform research in the field of psychology.

in cell A, what is the structure labeled X?
Answer:
Yo i dont know but when someone does please help me bro
Explanation:
In cell A, the structure labeled X is a centriole.
Centrioles are cylindrical organelles found in animal cells, usually existing in pairs called the centrosome. They play a crucial role in cell division by organizing and forming the spindle fibers during the process of mitosis and meiosis.
Centrioles are involved in the separation of chromosomes, ensuring that each daughter cell receives the correct number of chromosomes.
Additionally, centrioles are essential for the organization of microtubules in the cytoskeleton, which provides structural support and maintains cell shape.
Their function in cell division and cellular organization makes centrioles vital components of animal cells.

The form of cellular transport that expends the cell's energy is known as… *
Assisted transport
Passive transport
Active transport
Facilitated transport
Answer:
C- active transport
Explanation:
Because energy is required in this process, it is known as 'active' transport. Examples of active transport include the transportation of sodium out of the cell and potassium into the cell by the sodium-potassium pump. Active transport often takes place in the internal lining of the small intestine.
Answer: C. Active transport. In cellular biology, active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration—against the concentration gradient. Active transport requires cellular energy to achieve this movement. Please mark brainliest!
