Answer:
The spike will remain at 3-feet above the ground in 30 years time because the spike does not increase in height as the tree does.
Please find the explanation below
Explanation:
Living things including the trees stated in this question are capable of growth (in height and girth). According to this question, a spike is hammered into a tree base at 3-feet above the ground level. However, after 30 years, the tree grows to 100 feet but the spike will remain at 3-feet above the ground.
This is because the spike, which is naturally incapable of growth, will not grow alongside the tree. A plant (tree) undergoes growth at its apices or meristem i.e. the tree will elongate from the tip and not any other part. Hence, the tree will grow and leave the spike at its initial level.

1. For generating healthy cells to form replacement organs like brains
2. for directing differentation to treat diabetes and arthritis
3. for testing for possible side effects of a new cancer medication
4. for curing heart disease by regenerating damaged heart tissue
I HEARD THAT 4 IS NOT CORRECT SO PICK THE CORRECT ONE THA ISNT FOUR. ITS FROM EDGE2020
Answer:
1. For generating healthy cells to form replacement organs like brains
Stem cells can be used for curing heart disease by regenerating damaged heart tissue. The correct option is 4.
What is stem cell?Stem cells are the raw materials of the body, the cells that give rise to all subsequent cells with specific responsibilities.
Under the right conditions, stem cells divide to establish more cells known as daughter cells in the body or in a laboratory.
Bone marrow stem cells, for example, may be able to generate bone or cardiac muscle cells.
This research has resulted in early-stage clinical trials to assess the effectiveness and safety of the product in humans.
Adult stem cells, for example, are currently being examined in people suffering from neurological or cardiovascular disease.
Thus, the correct option is 4.

how are algae cells different from other cells
Answer:
In the case of the algae, each individual cell is responsible for absorbing its own water. This makes the algae nonvascular compared to the highly vascular plant species. In this connection, algae also lack several key structures that are normally present in ordinary plants like the leaves, roots and stem.
Algae are a group of aquatic organisms with autotrophic metabolism that are made up of eukaryotic cells and we can find unicellular or multicellular individuals.
Some characteristics of algae cells are:
• Cellular organization is eukaryotic (with the exception of blue-green algae), that is, they have a nucleus delimited by a double membrane, mitochondria, chloroplasts, endoplasmic reticulum, Golgi complex and lysosomes.
By definition, this type of cell is one that has a nucleus in which genetic material is stored. Compared to prokaryotic cells, eukaryotes have a large genome.
• The cell wall is made up mainly of cellulose and glycoproteins.
• In the algae cells we can find different reserve substances produced by metabolism.
The reserve substances are mainly starch, although we also find chrysolaminarin, laminarin, mannitol and paramilion in the different groups.
These substances form granules that are dispersed in the cell cytoplasm, in chloroplasts or in pyrenoids.
• They have structures of locomotion called flagella.
In different groups of algae, these organs vary in both number and shape, however, they typically present two flagella or multiples of two.
Therefore, we can conclude that algae are unicellular or multicellular photosynthetic organisms endowed with nucleus, cell wall, flagella and reserve substances.

Schwann would make statement II and Schleiden would make statement III
Explanation:
Schleiden, a German botanist and Schwann was a zoologist, both have found that the plants and animals are made up of cells, they both shared their research and observation with each other and made the conclusion that all living organisms are made up of cells.
As mentioned above Schleiden was a botanist so he must have concluded and described that all plant organs are made up of cells, similarly as zoologist he proposed that the cell must function properly in an organism.
