I think the correct answer would be body parts. Almost all multicellular organisms' needs are similar or the same. Like they need food to survive, they need to take in oxygen and the like. Due to this, organisms tend to have more or less the same parts.

Answer: The correct answer for the fill in the blank is oragnelles.

All cells found in multicellular organisms have similar needs. For instance, for energy requirements, most of the cells derive energy from ATP that is produced through cellular respiration.

For fulfilling the similar needs, most organisms have developed similar organelles. Organelles are the specalized membrane bound structures that serve the specific needs of the cell.

For example- A typical cell possesses organelles like Mitochondria, endoplasmic reticulum, golgi complex, ribosomes etc.

Mitochondria is the power house of all cells as most of the energy is derived from it in the form of ATP ( adenosine triphosphate).

Thus, similar organelles meet the similar needs of the organisms.

Apoptosis involves all but which of the following?
LenaWriter [7]

Answer:

Apoptosis does not involve:

c. lysis of the cell

Explanation:

Apoptosis is a programmed cell death that occurs under normal physiological conditions and in a controlled manner. Normally seen in cell turnover, embryogenesis, also involved in processes of immune, nervous and endocrine systems.

The main morphological and biochemical changes seen during the apoptosis are the fragmentation of DNA by endonucleases, nuclear, chromatin and cytoplasmatic condensation, apoptotic bodies formation (membrane bound-vesicles form of cell parts) and the phagocytosis (digestion) of those bodies by the scavenger cells.

Apoptosis is regulated by cell- signaling pathways, the caspases, a family of cysteine proteases, are the ones involved in the process.

In the process there is no lysis of the cell as this could lead to a inflammatory response (just happens in necrosis) which would affect contiguous cells, and will involve immune cells. In apoptosis there is just a membrane blebbing, but it does not loss its integrity.

Which explanation provides support for continental drift theory?
Luba_88 [7]

Answer and explanation:

Among the main evidences of the theory of continental drift, we can mention the fit of the lines of the coasts of several continents, In addition to the similarity between several relief structures and rocks in different continents (such as mountain ranges found in South America and on the east coast of Africa).

There are also records of fossils of identical extinct plants, found on the African continent and also in countries like Australia, India and Brazil, for example.

Identical reptile fossils have also been found in Africa and South America, in addition to several correlations in the distribution of aquatic dinosaur fossils that lived in common areas of the ancient supercontinent.
