Answer:

The correct answer is - option A. 0%

Explanation:

The zygote formation or fertilization in flowering plants occurs by the fusion of pollen of one plant with the ovum of another plant of the same species normally. This process includes the exchange of an equal amount of the genetic contribution from both plants.

The egg cell of the mother is responsible for the mitochondria and chloroplast of the progeny so the percentage of chloroplast genes provided via Plant R is 0% as ovum and egg cell comes from only plant Q.

percentage of chloroplast gene inherited from R plant is a)0%

Where do DAG and IP3 originate?
cupoosta [38]

Answer:

Option (4).

Explanation:

Phosphatidylinositol4,5-bisphosphate (PIP2) is the phospholipid present in plasma membrane. This lipid is important for the cell communication and cell signalling process.

The PIP2 can cleave and give two main products are DAG (diacylglycerol) and IP3 ( inositol 1,4,5-trisphosphate). These two molecules are important for the cell signalling.

Thus, the correct answer is option (4).

Inga [223]

Answer:

<em>The correct option is B) Scientific paradigm</em>

Explanation:

The scientific paradigm focuses on the infection and the microorganism for the occurrence of the infection. A scientific paradigm also refers to the treatment of these infections through pharmaceutical or surgical approaches. Hence, option B is correct.

Other options, like option A, is not correct because a holistic paradigm focuses on the connection between the mind, body and the soul. Option C is false because the analytical paradigm is not a part of the major health belief system.

55 Which of the following is an advantage of
Savatey [412]

<u>Answer</u>:

"It increases the mutation rate"  is an advantage of  sexual reproduction

<u>Explanation</u>:

The basic thing of evolution is fundamental, as it helps in generation of genetic variation on which the selection can act. Sexual reproduction leads to genetic diversity, and this genetic diversity leads to increase the mutation rate. Genetic diversity occurs because of two various cells which are combining together and biological assortment which happens at the time of cell division. Neutral genetic diversity in the population leads to high mutation rate.

Vera_Pavlovna [14]
Overuse of antibiotics is causing this resistance, we can let our bodies fight off bacterial infections naturally, stop the overuse of antibacterial soaps and cleansers, let our bodies build up resistance to these bacterias naturally through natural exposure.
