In flowering plants what structure containing DNA is transported from one plant to another
azamat

Answer:

Pollen

Explanation:

Flowering plants are plants classified as Angiosperms. They are the most diverse group of plants in the Kingdom Plantae. Angiosperms or flowering plants as their name implies are characterized by the possession of reproductive structures called FLOWER. The male reproductive flower called STAMEN produces their gamete in a structure called POLLEN while the female reproductive flower called PISTIL contains an ovary that produces egg cells called OVULES.

In flowering plants, the pollen of a male flower is transported to the receptive part of the female flower called STIGMA in a process called POLLINATION. The pollen contains the gamete (sperm cell) that conveys the genetic material (DNA) of the male plant. A fertilized ovule develops into a seed, hence, the reason flowering plants are called SEED-BEARING.

Therefore, pollen is the structure containing the genetic material (DNA) that is transported from one plant to another (same species) in flowering plants.

How is the proportion of hydrogen to helium in the Sun's core changing over time?
harina [27]

Answer: The percentage of the helium will increase with the decrease in the percentage of the hydrogen.

Explanation:

The conversion of the hydrogen into helium occurs by the nuclear fusion of the hydrogen atoms. This process reduces the hydrogen density and reduces the energy production inside the core region. Typically, in the core region of the hydrogen is converted into the helium by nuclear fusion. Four hydrogen atoms are collectively fuse to form one atom of helium. This process involves the production of heat energy.

A planet has an average distance to the sun of 0.66 AU. In two or more complete sentences, explain how to calculate the orbital
MakcuM [25]
We can use the formula for orbital time period:
T² = (4π²/GM)a³; where T is in Earth years, a is distance from sun in AU, M is the solar mass (1 for the sun), G is the gravitational constant.
In the given units, 4π²/G = 1
T² = 0.66³
T = 0.536 Earth years = 195.71 Earth days

Which process is most likely to result in a gene providing antibiotic resistance to be found in a viral genome
Lina20 [59]

Answer:

<em><u>There are two important types of genetic mechanisms that can give rise to antibiotic resistance: mutation and acquisition of new genetic material. In the case of mutation, the rate at which resistance develops can be attributed to the rate at which bacteria mutate.</u></em>
