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.

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.

What condition is caused by carbon dioxide, methane, and water vapor trapping heat in the Earth's atmosphere?
A biomagnification
B greenhouse effect
C photosynthesis
D transpiration
The condition that is caused by carbon dioxide, methane, and water vapor trapping heat in the Earth's atmosphere is known as the greenhouse effect. Thus, the correct option is B.
What is the Earth's atmosphere?The earth's atmosphere may be defined as the significant presence of a layer of various gases that surrounds the whole planet. It is known that the Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases.
Carbon dioxide, methane, and water vapor are considered greenhouse gases that ultimately capture the heat radiations from the sun and liberate the earth's atmosphere. As a result of this, the average temperature of the earth's surface has gradually increased for four to five decades.
This is all known as the greenhouse effect. The Greenhouse effect may be defined as the phenomenon of keeping the earth warm due to the presence of certain gases in the atmosphere that captures heat from the sun.
Therefore, the condition that is caused by carbon dioxide, methane, and water vapor trapping heat in the Earth's atmosphere is known as the greenhouse effect. Thus, the correct option is B.

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!

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.

Cells are considered the basic units of life in part because they come in discrete and easily recognizable packages.
