Almost all living creatures on our planet depend on plants for food and oxygen, either directly or indirectly. So, if all the plants disappeared, eventually so would almost all the other life. Also, Earth would be hotter.
New techniques to produce cells with the characteristics of embryonic stem cells include Parthenogenesis, retroviral transduction of transcription factor genes into adult skin cells (iPS), and somatic cell nuclear transfer (SCNT).
<h3>What is
embryonic stem cells?</h3>
- Pluripotent stem cells called embryonic stem cells are produced from the inner cell mass of a blastocyst, a preimplantation embryo in its early stages.
- Four to five days after fertilization, human embryos reach the blastocyst stage, consisting of 50 to 150 cells.
- Embryonic stem cells (ESCs) are stem cells that come from an embryo's core mass of undifferentiated cells.
- In laboratories, typically fertility clinics, 4- to 6-day-old embryos are used to produce human embryonic stem cells.
- The core embryonic cells are taken out and put in a dish with the nutrients they require to thrive.
- Theoretically, embryonic stem cells are capable of mass-producing any kind of tissue.
- These cells are used by researchers to investigate disease and development in the hopes of developing therapies.
- A single embryo's two or three dozen cells can produce millions of embryonic stem cells in about six months.

Hey there! :D
A verb phrase is a phrase that defines the action. It contains the verb in the sentence.
"walked" is the verb, so "A" Have walked, is the answer.
I hope this helps!

One cell can divide into two new cells. This is called mitosis. The process of cell division goes through various stages. First the cell nucleus divides into two. A new cell surface membrane then severs the cell divides. The two new cells are called daughter cells and they are small. They will grow larger. they grow by getting nutrients from the food that is eaten. Once they grow to full size they can also reproduce or divide. If cells divide more quickly than they should, or divide in the wrong way, diseases may develop.
I therefore, think all your answers are correct.
