Answer: D. determining the precautions
Explanation: its pretty difficult to just estimate whether cause theres always a chance its gonna change into something
1. The cells would be for repair.
2. Cells grown in serum free or reduced medium are termed donor cells starved. It is done by biologist to synchronize all the cells in same phase of cell cycle.
Explanation:
1. If a fully developed mammary gland cell divides it would be daughter cells for repair by mitosis or during turn over of normal cells.
2. The term starved for donor cells means to deprive the cell of nutrients by growing them in reduced or serum free medium.
The reason biologist use this technique is to synchronize all the cells in same phase of the cycle as Go phase of cell cycle.
3.In the egg containing the donated somatic cell is reprogrammed by host machinery. The enucleated egg incorporated with somatic cell nucleus is given an electric shock. The cell becomes viable ready to divide and produce a viable organism.
After continuous mitotic divisions, cell becomes blastocyst.
This furthur divisions will produce organism not ball of mammary gland cells. The plueripotent stem cells are obtained by this technique.
Answer:
The scientific method is a methodology to obtain new knowledge, which has historically characterized science, and which consists of systematic observation, measurement, experimentation, and the formulation, analysis and modification of hypotheses.
Explanation:
The main characteristics of a valid scientific method are falsifiability, and the reproducibility and repeatability of the results, corroborated by peer review. Some types of techniques or methodologies used are deduction, induction, abduction, and prediction, among others.
The scientific method encompasses the practices accepted by the scientific community as valid at the time of exposing and confirming their theories. The rules and principles of the scientific method seek to minimize the influence of the subjectivity of the scientist in his work, thus reinforcing the validity of the results, and therefore, of the knowledge obtained.
Answer:
We can determine the past arrangement of leaves on a bare twig by looking at the arrangement of axillary buds and leaf scars.
Explanation:
- The arrangement of leaves on a branch or stem is called phyllotaxy.
- Leaves are formed at stem nodes.
- They bear axillary bud on their axil.
- Axillary bud give rise to flowers and new branches.
- When leaves shred off we can determine their phyllotaxy by looking at the axillary buds on the nodes.
- When leaves fall off the stem, they leave scars at the nodes, these scars can also be considered to find out the attachment of leaves and phyllotaxy.
Common leaf arrangements are:
- Alternate.- When one leaf arises at each node and successive leaves develop on alternate sides .se.g. As seen in Barberry
- Opposite- When two leaves arise at one node and on the opposite side of the stem. E.g as seen in maple.
- Whorled.- When three or more leaves arise at a node forming a whorl.
Answer:
The modular type of strategic techniques are highly modular in their working and can be very useful for capturing concentrated resources or widespread (dilute) resources. The modular design in a capturing technique enhances the chances of better resource capturing whether it is concentrated or diluted.
The modular design works like it has several hands, that can perform all of their work by own greatly decreasing time required for capturing.
