Explanation:
Some of the energy from the Sun absorbed by maize when it photosynthesises is transferred to the locusts when they eat the plant. So biomass is transferred. Then some of the biomass in the locust is transferred to the lizards when they are eaten and so on.
hope this helps you
have a good day :)
D. Multiple cells have multiple, distinct functions. Cells do develop and grow (even single-celled organisms grow), but they grow in an organized manner.
Answer:
gene therapy, cloning and genetic engineering
Explanation:
Gene therapy is the replacement of faulty defectie genes with the normal ones aimed at correcting genetic disorders. In somatical gene therapy, genetically modified organisms, e.g., viruses are used to carry the normal gene and introduce it into the affected cells. This is used to treat lung cystic fibrosis.
Cloning is a type of reproduction where a group of cells arise from single individual cells without fertilisation. The nucleus from a fertilised ovum is removed and replaced with a diploid nucleus of a cell from the mammary glands of another sheep.
Genetic engineering deals with identification of desirable genes, altering, isolating and transferring the gene from one living organism to another.
Answer:
Explanation:
Cell specialization is also called cell differentiation. Through this process, specialized cells form from the unspecialized cells. Then many cells are formed and determined to form specialized functions.
The stem cells are the unspecialized cells which form a different kind of specialized cells.
The muscle cells, nerve cells, sperm cells, red blood cells are specialized cells perform different specialized functions. All these cells arise from stem cells. The nerve cells receive impulse, muscle cells can contract, etc.
There are certain inductive signaling genes that send the signal to the differentiated cells. These signaling molecules are called ligands. These ligands move to another cell to produce specialized cells. In other words, there are some transcription factors and genes responsible for such cell differentiation and the formation of specialized cells.
Another example is zygote, which is an unspecialized cell. This is also a totipotent cell that has the potentiality to reproduce different cells.
Answer: Isn't evolution just a theory that remains unproven?
Are all species related?
What is a species?
What do genes have to do with evolution?
What role does sex play in evolution?
Is evolution a random process?
Are evolution and "survival of the fittest" the same thing?
Explanation: I'm not sure if this is the anser but I just searched your question up and this came up.
