the fertilization of ovules from plant Q by pollen from plant R results in the productions of seeds. What percent of the genes i

n each offspring's chloroplasts wioll have been inherited from plant R
Biology
1 answer:
Helga [31]2 years ago
6 0

Answer:

The correct answer is - zero or 0%.

Explanation:

The fertilization in flowering plants takes place by fusing the pollen of one plant or flower with the ovum of another plant or flower of the same species normally and form a zygote. The zygote gets an equal amount of genetic material from both parent plants by the process f exchange of the genetic material.

The ovum or the egg cell of the plant is considered as the mother and the mother is responsible for the chloroplast And mitochondria of the progeny so in this case, the ovum and egg cell comes from the only plant Q thus, the percentage of chloroplast genes provided via Plant R is 0%.

In comparing photosynthesis and cellular respiration, which of the following is TRUE?
Salsk061 [2.6K]

Answer:

 Photosynthesis takes place in the chloroplasts of cells. This process is what gives energy to all living organisms either directly or indirectly.

Explanation:

Cellular respiration, on the other hand, is the process by which living things convert oxygen and glucose to carbon dioxide and water, thereby yielding energy.

Consider this scientific name: Homo Sapiens. What is wrong with the way it is currently written? Group of answer choices Genus n
nika2105 [10]

Answer:

Species name should both be lowercase

Explanation:

According to the rules of binomial nomenclature:

1. The scientific name of an organism is represented by two names- the first genus and the second by its specific epithet.

2. The first alphabet of the genus should be in the uppercase and the first alphabet of the species will be the lowercase.

In the given question the scientific name of humans has been provided as Homo Sapiens in which the first alphabet of the specific epithet is provided in uppercase which must be in the lowercase as "sapiens".

Thus, species names should both be lowercase is correct.

If you treated embryos with a Notch inhibitor how would this affect the specification of venous and arterial endothelial cells?
Alisiya [41]

Answer:

d. all endothelial cells would be venous

Explanation:

The Notch signaling pathway is a cell signaling system which consist basically of 4 NOTCH genes ( NOTCH1, NOTCH2, NOTCH3, and NOTCH4) each of them having the information to build a particular cell membrane receptor protein.

It has been demonstrated in zebrafish embryos that Notch signaling are highly determinant factors during vascular development, and a key function of these genes was specifically to regulate the differentiation of arterial fate in endothelial cells.

Notch signaling-deficient embryos showed a loss of expression of arterial markers such as ephrinB2 from arterial vessels with an accompanying expansion of venous markers into normally arterial domains. In contrast, embryos in which Notch signaling had been ectopically activated, meaning an activation out of "proper" place (where not expected, e.g. venous endothelial), exhibited the contrary phenotype, this is a suppression of vein-specific markers with ectopic expression of arterial markers in venous vessels.

To summarize, when Notch is supressed (in this case inhibited with a specific Notch inhibitor) arterial fate of endothelium is not followed, and venous fate is stablished. Thus, endothelial cells (those expected to form venous tissues but also arterial ones) would specified as venous.
