The process of single-cell destruction or programmed cell death is known as apoptosis.

Apoptosis is a type of programmed cell death which occurs in multi-cellular organism in contrast to necrosis which is a kind of cell death occurring due to acute cellular injury. Apoptosis is a well-controlled and programmed process which produces apoptotic bodies or cell fragments that are engulfed by the phagocytic cells and removes them before the spilling of cell content which can damage the surrounding cells.

The initiation of apoptosis takes place by two pathways: intrinsic pathway when the cells kill themselves sensing cell stress and extrinsic pathway when the cells are killed due to the signals obtained from other cells.

Roles of bones in bony fish include which of the following?
Rina8888 [55]

Answer:

D All of the above

Explanation:

Like our bones, bones in fish can provide general protection and support to their body.

(Fun fact, jellyfish do not have bones, so when they are out of the water, they loses their bell shape structure and looks more like a flat piece of jelly. But fish tends to look the same when it is in water and out of water.)

The bone is also where the muscles will attach to, which allows for movement.

(Imagine our fingers, the muscles in our fingers are attached to our bones, which allows us to do things like typing.)

Bones can also protect the fish's brain.

(Brain can be very fragile and soft, so having a hard structure around it can protect the brain. It's kind of similar to protecting the liquid egg in an egg shell.)

Help me, please with this :)
WARRIOR [948]

Answer:

Please find the answer to the blank spaces in each statement of the attached image in CAPS.

1. All energy comes from the SUN

2. Plants, algae and some bacteria capture energy by PHOTOSYNTHESIS in their CHLOROPLAST.

3. Plants, animals, fungi, protists, and most bacteria release energy by RESPIRATION in their MITOCHONDRIA.

Note:

- Photosynthesis requires CARBON DIOXIDE (CO2) and WATER (H20) to make GLUCOSE (C6H12O6) and OXYGEN (02)

- Respiration requires GLUCOSE (C6H12O6) and OXYGEN (02) to make CARBON DIOXIDE (CO2) and WATER

Explanation:

The image in this diagram is depicting how energy flows from the ultimate source, which is the SUN to other living organisms. Plants, algae and some bacteria have the ability to capture energy from the SUN using pigments in their CHLOROPLAST in a process called PHOTOSYNTHESIS, which they use to synthesize their food. The process of photosynthesis requires CARBON DIOXIDE (CO2) and WATER (H20) to make GLUCOSE (C6H12O6) and OXYGEN (02) gas.

However, on the contrary, virtually all living organisms including: Plants, animals, fungi, protists, and most bacteria etc. release energy via an organelle called MITOCHONDRIA in a process called RESPIRATION. The process of respiration requires GLUCOSE (C6H12O6) and OXYGEN (02) to make CARBON DIOXIDE (CO2) and WATER.

Answer:

What makes us human the most is our self-awareness and the ability of philosophical thought.

We understand we exist on Earth and wonder why the sky is blue, which is a trait no other species possesses.

Explanation:

Orangutans, chimpanzees, gorillas, bottlenose dolphins, elephants, orcas and bonobos all have self-awareness. But still don't wonder why the sky is blue.

Animals were seen capable of doing all the other factors.

Under a microscope, the cells of mushrooms, plants, and animals all have visible nuclei. this makes them all:
zalisa [80]

Answer: The correct answer is -

Eukaryotes.

Eukaryotes are the organisms that possess a true nucleus (containing the DNA, which is the genetic material) and the membrane bound subcellular compartments ( also known as cell organelles) such as golgi complex, endoplasmic reticulum, mitochondria.

As per the given information in the question, cells of mushrooms, plants, and animals all have visible nuclei under a microscope.

Thus, it indicates that these organisms are eukaryotes.
