Please help!!! I don't know how to tell if they self pollinate or not.

Answers

Answer:

The first flower can self pollinate because it is open, so the wind will pollinate it.

Explanation: Flower b will not self pollinate because it is not open, so it will not pollinate until a bird or moose or any other animal comes and eats it, then poops it out, so the seeds get planted.

Answers

Answer:

I would prefer to have city water because you don't have to worry about it getting polluted unlike well water. The city water is maintained by the city while with the well water, you maintain it yourself. Even though it can be pricey, most people live in the city anyway, so there is easier access to it.

Explanation:

Answer:

Well Water

Explanation:

I would prefer well water, because city water had a lot of chemicals, and city water filters out minerals that are good for the body. Also, well water tastes ten times fresher than city water. Also, well water is easy to obtain if you already have a well, all you have to do is wither pump it up, or use a basket to scoop some out.

Explain why parallax was a problem in proving the heliocentric model of the solar system.

Answers

Yes that’s right absolutely

Copernicus himself asserted that the absence of parallax meant that the stars were far beyond the planets. The failure of heliocentrists to detect it proved nothing, whereas a successful detection would be strong evidence for heliocentrism.

What is heliocentric model?

The astronomical model in which the Earth as well as planets revolve around the Sun at the center of the universe is known as heliocentrism. Historically, heliocentrism was opposition to geocentrism, which centered on the Earth.

Galileo wanted to believe that his new invention, the astronomical telescope, could assist him in proving that the Sun was the center of our solar system and that Earth was only one of many planets orbiting our star.

Copernicus himself claimed that the lack of parallax indicated that the stars were far beyond the planets.

Failure to detect it by heliocentrists proved nothing, whereas successful detection would be strong evidence for heliocentrism.

Thus, parallax was a problem in proving the heliocentric model of the solar system.

O c. Farm A is a grass-fed pasture for beef production, whereas Farm B is a traditional

ction, whereas Farm B is a cage
O d. Farm A is a concentrated animal feedlot for beef
free farm for poultry.

Answers

Answer:

b. Farm A is a cage-free farm for poultry, whereas Farm B is an industrial poultry farm.

Explanation: the average days in any 12-month period suggest that farm b cages while farm a does not. The antibiotic usages for farm b also suggest it is an industrial (caged) farm because most cage-free and non-industrial farms do not rely on heavy use of antibodies.

The Farm A is a cage-free poultry farm while Farm B is an industrial poultry  farm.

Farm A:

The caged day are zero means all birds can move freely in the farm area.They are not eat antibiotics to avoid infection.

Farm B:

Most of the time in year, birds are caged. They fed antibiotic to all to avoid infection in the cage.

Therefore, the Farm A is a cage-free poultry farm while Farm B is an industrial poultry  farm.

Answers

Each organelle, in a cell, works with all of the other organelles to maintain balance, or homeostasis. The organelles have specific functions such as the mitochondria, which create energy, and the ribosome, which translates RNA into proteins. Because these cells work together, the body is able to maintain homeostasis.

Help me on this please

Answers

Explanation:

A.

The transpiration stream that passes through a plant may follow an apoplastic route, with low resistance to flow, or a cell-to-cell route, in which cellular membranes impede water flow. However, passage of water through membranes can be facilitated by aquaporins thereby decreasing resistance. We investigated the relationship between transpiration, which can be down-regulated by abscisic acid (ABA) or by high humidity, and the osmotic water permeability (Pos) of protoplasts. By using leaf protoplasts of wild-type (wt) Arabidopsis thaliana plants and of mutants that are low in ABA (aba1) or insensitive to ABA (abi1 and abi2), we found that protoplasts from aba1 and abi mutants have very low Pos values compared with those from wt plants when the plants are grown at 45% relative humidity. High values of Pos were found 3 h after the addition of ABA to the culture medium of aba1 plants; addition of ABA to abi plants did not restore the Pos to wt levels. There was no such increase in Pos when excised leaves of aba1 plants were treated with ABA. When the transpiration stream was attenuated by growing the plants at 85% relative humidity, the Pos of protoplasts from all plants (wt and mutants) was higher. We suggest that attenuation of the transpiration stream in whole plants is required for the up-regulation of the Pos of the membranes, and that this up-regulation, which does not require ABA, is mediated by the activation of aquaporins in the plasma membrane.

B.

The influence of abscisic acid (ABA) on carbon metabolism, rate of photorespiration, and the activity of the photorespiratory enzymes ribulose bisphosphate oxygenase and glycolate oxidase in 7-day-old barley seedlings (Hordeum vulgare L. var. Alfa) was investigated. Plants treated with ABA had enhanced incorporation of labeled carbon from 14CO2 into glycolic acid, glycine, and serine, while 14C incorporation into 3-phosphoglyceric acid and sugarphosphate esters was depressed. Parallel with this effect, treated plants showed a rise in activity of RuBP oxygenase and glycolic acid oxidase. The rate of photorespiration was increased twofold by ABA treatment at molar while the CO2-compensation point increased 46% and stomatal resistance increased more than twofold over control plants.
