Answer and Explanation

The normal microbiota that harbouring an R plasmid will transmit its R plasmid to the normal microbiota because the normal microbiota does not have R plasmid after transmission of R plasmid its increases the resistance capacity of normal microbiota. This is the significance of normal microbiota that harbours an R PLASMID.

Answer:

That microbe can potentially transfer the R plasmid to a member of the normal microbiota.

Explanation:

Plasmids are extrachromosomal circular DNA molecules. They have the ability to replicate independently and generally have few genes. It is worth noting that in a cell several copies of plasmids can be found and that they are frequently transferred from one cell to another. Thus, we can conclude that a microbe can potentially transfer the R plasmid to a member of the normal microbiota.

Plasmids generally have genetic information that is not extremely essential for the survival of the bacteria, but they are usually related to some adaptive function for special situations. As an example, we can mention those plasmids that guarantee resistance to antibiotics and those that increase the probability that a bacterial cell will cause some disease.

Circulatory system
The circulatory system is the transport system for endocrine information. While the nervous system uses neurons, the endocrine chemicals and hormones must circulate through the body via blood vessels. Many glands in your body secrete hormones into the blood.

Which of the following statements about the nuclear envelope is false?

Evgesh-ka [11]

Answer:

b) The nuclear envelope is continuous with the Golgi apparatus.

Explanation:

The nuclear envelope is a nuclear membrane composed of two lipid bilayers: inner and outer membrane and perinuclear space between them. Its outer membrane is continuous with the endoplasmic reticulum. Nuclear pores that are part of this envelope allow the movement of molecules in and from the nucleus (e.g. mRNA formed during transcription should be transported into cytosol through the pores).

The sickle-cell allele, which is recessive, causes anemia but confers resistance to malaria in individuals who possess it. Howev

masha68 [24]

Answer:

A. the heterozygote advantage

Explanation:

Heterozygote advantage is the condition where the heterozygous individual has higher relative fitness than both homozygous dominant and homozygous recessive individual. This means that the heterozygote individual has higher chances of surviving than both the homozygous counterparts. Sickle cell anemia is a recessive inherited disorder in which oxygen carrying hemoglobin has an abnormal structure. Hence, the resultant RBCs are not spherical but have crescent sickle shape. The oxygen carrying capacity of such RBCs is drastically reduced but they are unaffected by malarial parasite due to their abnormal structure.

A person with both the recessive genes for sickle cell would not be able to survive due to insufficient oxygen transport in body.
A person with both the dominant genes would be free of sickle cell anemia but in case of malaria would not be able to survive as the normal RBCs would be hijacked by the parasite.
A hetrerozygote would survive both in malaria and sickle cell condition since he has enough normal RBCs for oxygen transport but also has sickle cell RBCs which are unaffected by malarial parasite.
