false or b
Explanation:
Answer:
chloroplast.
Explanation:
Chloroplasts are specialized organelles found in plant cells and some other organisms, such as algae. They are responsible for carrying out photosynthesis, the process by which plants convert sunlight, water, and carbon dioxide into glucose (energy) and oxygen.
Chloroplasts have a double membrane structure and contain their own DNA and ribosomes. They are green in color due to the presence of chlorophyll, a pigment that captures light energy for photosynthesis.
The presence of chloroplasts in plant cells allows them to produce their own food through photosynthesis, whereas animal cells do not possess chloroplasts and rely on obtaining nutrients from external sources.
In summary, chloroplasts are organelles found in plant cells but not in animal cells. They play a crucial role in photosynthesis, enabling plants to convert light energy into chemical energy and produce their own food
Answer: Autoimmune response
The immune system is the body's defense against germs like bacteria and viruses. When it senses these germs, it sends out an army of fighter cells to attack them. This called the immune response.
Autoimmunity is the immune response of an organism against its own healthy cells and tissues. This is always disadvantageous to a person because it mistakenly attacks our body. Autoimmune diseases which result from this now affect 24 million people. Examples of autoimmune diseases are rheumatoid arthritis, multiple sclerosis, thyroid disease, inflammatory bowel disease and lupus.
Answer:
5. ee, attatched earlobes
8. Ee, free earlobes
Explanation:
the following is NOT a function of
these?
A. allows the strand to leave the nucleus
B. helps the strand attach to a ribosome to be
translated
C. signals that introns need to be spliced out
D. protects the strand from enzymes
Answer: The answer is C
Explanation: The answer is signals that introns need to be sliced out, I got it right!
C. signals that introns need to be spliced out. The 5' cap and the poly A tail of an RNA molecule serve to allow the molecule to exit the nucleus, attach to a ribosome, and protect from degradation. They do not signal for introns to be spliced out.
The RNA molecule has a 5' cap and a Poly A tail at the 3' end. These modifications play a few key roles in the functionality of the RNA molecule but the statement 'signals that introns need to be spliced out' (option C) is NOT one of the functions of these modifications.
The 5' cap allows the RNA to exit the nucleus and attach to a ribosome, while the poly-A tail helps stabilize the RNA, aids in the exit from the nucleus, promotes translation, and protects the RNA strand from enzymes that degrade RNA from the 3' end. Neither of these modifications signal for introns to be spliced out, that is primarily the function of spliceosome complex which recognize specific site sequences within the RNA.

B. ecological footprint.
C. habitat.
D. ecological sustainability.
Not habitat I missed it. Should be ecological footprint
c. organ
b. tissue
d. organism
A group of organs working together to perform a certain function is referred to as an organ system, option (a) is correct.
An organ system consists of multiple organs that collaborate and coordinate their activities to carry out specific functions necessary for the overall functioning and survival of the organism. Each organ within the system has its own unique structure and function, but they work together synergistically to achieve a common goal.
Examples of organ systems in the human body include the respiratory system, circulatory system, digestive system, nervous system, and many others. These systems are interconnected and interdependent, ensuring the proper functioning and homeostasis of the organism as a whole, option (a) is correct.

Answer:
it is organ system
Explanation: all it is just process of elimination because a tissue is a group of cells working together not organs and an organism is like an animal or human not an organ and organ is not it because it is a group of them wwhy would they call it an organ if it is in a group of the thing so there u go hope this helps pls read this :)
