Answer:
The blastocyst is a fertilized egg
Explanation:
the inner cell mass (ICM, from which the fetal tissues develop) and the trophectoderm (which will form mostly extraembryonic tissues such as the placenta
The plant may do this to keep water in and maintain its ability to do photosynthesis.
Answer:
DNA do not normally cross the nuclear membrane.
Explanation:
DNA (Deoxyribonucleic acid) is present in the nucleus which contains the genetic information of an organism. Nucleus is necessary for whole the process of cell division and initiation. During cell division DNA plays a most important role carrying of genetic information of old cell to the newly synthesized cells, which only occurs during cell division.
All processes like replication and transcription needs enzymes which are normally found in the nucleus. So, for the protection of DNA keeping DNA within the nucleus and do not cross the nuclear membrane. If DNA is floating in the cytoplasm than DNA can not be transcribed its information into RNA and this process is known as transcription process (DNA into RNA).
The steps in taking a ridge count from a fingerprint are as
follows:
1. Draw an imaginary line from the center of the core to the
edge of the delta
2. Count all the ridges that touch or cross the imaginary
line
3. The core and delta should not be included in the counting
4. Incipient ridges are never to be counted regardless of
where they appear
NUMERICAL VALUE
ASSIGNED TO RIDGES
An island ridge – One count
A short ridge – One count
A long ridge – One count
Abrupt ending ridge – One count
A ridge that bifurcates across the imaginary line – Two counts
A bifurcating ridge whose point of origin is on the line of
count – Two counts
Eyelet ridge – Two counts
Intersection of two enclosures – Two counts
The core is located on ending ridge which touches the inside
of the innermost recurving – Four counts
