Angiosperms may self-fertilize if pollen from a flower is transferred to egg cells in the same flower, or they may cross-fertili

ze. Carried on the wind or by other means, pollen grains from other flowers may land on the sexual organs of a flower and fertilize it. Can you think of other ways that cross-fertilization of flowers might happen (besides by the wind)? PLEASE HELP ME OUT

Answer: Pollination, the transfer of pollen from flower-to-flower in angiosperms or cone -to-cone in gymnosperms, takes place through self-pollination or cross-pollination.

Cross-pollination is the most advantageous of the two types of pollination since it provides species with greater genetic diversity.

Maturation of pollen and ovaries at different times and heterostyly are methods plants have developed to avoid self-pollination.

The placement of male and female flowers on separate plants or different parts of the plant are also barriers to self-pollination.

Describe the path taken by water molecules from the soil until it reaches a mesophyll cell of a leaf to be made into sugar
pychu [463]

Water is taken up through the xylem until it reaches a leaf, where it diffuses out into the surrounding mesophyll cells. Water diffuses from the mesophyll cells to the surrounding intercellular air spaces as water vapour, and finally, out of the leaf through the stomata.

Which goes where ? Mitosis Vs. Meiosis
nika2105 [10]

Answer:

Mitosis, Meiosis, and both are written below

Explanation:

Mitosis: produces more somatic (body) cells, purpose is for healing and growing, the daughter cells are exact replicas

  • This is because mitosis occurs in body cells and is used for growth, so all the daughter cells are the same.

Meiosis: results in sex cells (gametes), results in eggs and sperm, purpose is for creating new individuals (eventually), each daughter cell is different, has 2 separate division stages

  • This is because meiosis occurs in gametes and is used in reproduction.

Both: Chromosomes need to replicate before the whole process begins, a form of reproduction

  • This is because both are reproducing (they are dividing) and DNA must be replicated so each daughter cell has it.

Maria wakes up in the morning and takes a shower, drinks a glass of water, washes her clothes in the laundry machine, and then g
Ivan

The correct option is this: MARIA'S WATER USE IS CONSUMPTIVE.

Water use can be consumptive or non consumptive. Consumptive water use refers to the process of using water in such a way that the water used can not be returned to the water resources system.

The water that Maria used to shower, the one she drank and the one she used to wash her laundry are waste water, which are not returned to the central water resources system, thus, Maria's water use is consumptive.
