Answer:
This technique is called in-vitro fertilization.
Explanation:
In-vitro fertilization (IVF) refers to a form of assisted-reproduction technology in which the encounter of male and female gametes takes place outside the female organism (such as a human patient, in this case). IVF may be employed in several situations, including:
- Abnormalities in the female reproductive tract which impair the flow of the ovum into the uterine cavity (e.g. blocked fallopian tubes).
- Abnormally low sperm counts.
- Surrogate pregnancy.
Answer:
All the options are going to reduce the time to get in or get out materials from the cell.
Explanation:
If the cell is thin and flat, the membrane will be thinner also, hat means that the particles that want to get in, could enter easily because the lipid layer is not so thick.
If the cell has extensions such as cilia, it will increase the membrane area, the contact area, that means that it will increase the possibility for a substance to get inside, for example, if a molecule can easily get in, if there are a bigger area, more molecules can enter to the cell.
If the cell uses vesicles to move materials, also will increase the probability to carry substances inside the cell because there are more "buses" to carry "passengers" inside.
Answer:
The correct answer will be option-A.
Explanation:
Deoxyribonucletoide stands for DNA, the genetic material of the organisms. This DNA is the hereditary material of the organism coding molecule is passed on to the generations, so it has to be replicated, form a transcript and translated to proteins.
The DNA transcription process produces a transcript chemical molecule with exactly the same language as of DNA called RNA. This RNA carries the information for the synthesis of protein molecule so it acts as a messenger molecule and is known as mRNA.
Other types of RNA molecules are produced by the DNA which is named depending on the functions like transfer RNA or ribosomal RNA.
Thus, option- A is the correct answer.
