Explanation:

hope it is helpful

Answer 2

Answer:

Explanation:

: There's only one stable, long-lasting biosphere that we know of. It's the Earth. It shouldn't surprise you that human attempts to create sealed systems don't generally fare very well. The International Space Station, despite efforts to recycle everything possible (including converting urine to drinkable water--do you still want to be an astronaut?) to reduce costs, couldn't sustain life for long without a steady supply of provisions from, and garbage hauling back to, Earth. You know they try hard because, if all goes as planned, it costs about $10,000 to put a pound of payload (supplies) into Earth orbit. The BioSphere 2 project in Southern Arizona was an interesting and costly effort, but the original studies weren't very scientific and it proved quite difficult to keep just a handful of humans alive for a relatively short period of time. You can buy tiny sealed marine ecosystems enclosed in glass. They are beautiful curiosities, but the one I bought for my wife lasted less than a year before crashing. Among the crazier justifications for space exploration is that when (note the assumption of inevitability) we ruin the Earth, we will need new places to live (and, presumably, ruin). Unless or until we can do a lot better at building self-contained ecosystems, it would be a far better use of human effort to focus on preserving the only one we've got. Not only that but, if we make the Earth uninhabitable, I'm not sure we deserve to live somewhere else. But the challenge itself is interesting, and the scientific questions you can ask in the process of understanding, building, and trying to maintain such a system are valid. We're going to give it a try. Good luck! There's a Nobel Prize in it.

What is a spring tide? When and why does it occur?

Answers

Answer:

Spring tides happen just after every full and new moon, when the sun, moon and earth are in line. That's when lunar and solar tides line up and reinforce each other, making a bigger total tide.

A spring tide occurs when there's a new or full moon. Because it follows the moon's lunar cycle, a spring tide happens twice per month. With the moon and sun roughly aligned the tides of Earth are on average slightly larger than usual.

Answers

A particular plant has two alleles that control the length of its stem. T represents the dominant allele that codes for a tall stem, and t represents the recessive allele that codes for a short stem. Based on the Punnett squares, which two statements are true about the genotype of the plant’s stem length?

First Generation

__t_ t

T Tt Tt

T Tt Tt

Second Generation

__T_ t

T TT Tt

t Tt tt

Select all the correct answers.

A) Plants with short stems are homozygous for that trait.

B) Plants with tall stems are always homozygous for that trait.

C) Both parent plants in the second generation are heterozygous.

D) Both parent plants in the second generation are homozygous.

The correct answers are options A and C.

How, explain your answer briefly?

The Statement A says that the plants, which have a short stem is homozygous for the trait. According to the question, the allele for the short height is recessive. A recessive trait can only be observed, when the dominant allele is not at all present. Hence, the plant must have tt allele, so, the plant having short stem would be homozygous recessive.

The statement C says that the both parents in second generation are heterozygotes. It is given that the parents in the second generation have aa genotype Tt. In this case, both the alleles are different, hence, the parent plants are heterozygotes.

Thus, this could be the answer.

Dihybrid crosses
1. In man, assume that spotted skin (S) is dominant over non-spotted skin (S) and that wooly hair (W) is dominant over non-wooly hair (W). cross a marriage between a heterozygous spotted, non-wooly man with heterozygous wooly-haired, non-spotted woman. Give genotypic and phenotypic ratios of offspring?​

Answers

Explanation:

The phenotypes and genotypes of the progeny can be determined by a dihybrid cross of the parents.

The heterozygous male will have the genotype 'SSww' and the heterozygous female will have the genotype 'ssWW'.

When crossed, the F1 offsprings will have a hybrid genotype of 'SsWw'. These offsprings are heterozygous with spotted skin and wooly hair.

On self-crossing of the F1 hybrids, we find four different combinations of the alleles- SW, Sw, SW and sw. The probability of getting each of these combinations is 1/4.

Hence, the probability of any dihybrid type is 1 out of the 16 possible genotypes. Using Punnet square, we find

9 SSWW: 3 SSww: 3 ssWW : 1 ssww

This is the phenotypic ratio of the offsprings.

The ratio of the possible genotypes will be 1:2:1:2:4:2:1:2:1.

1.What is one cost and benefits of double window glazing?
2.what is one cost and benefit of green roof?

( Science teachers if you see this please answer )

Answers

Explanation:

1.Warmer in the winter – Double glazing is great for insulation, it can also help capture natural heat and store it in the winter. This is a great way of keeping your home insulated in the winter months.

Energy cost savings – Less energy is used up to heat or cool a room when double glazed windows are installed, this results in lower energy bills and money being saved. Adding more layers of glazing will increase the insulation levels and save more money.

Cooler in the summer – Double glazed windows can trap some of the rays coming through the windows on a hot summer’s’ day causing your room to be cooler. This means less air-conditioning is required.

Safety – With more units being on double glazed windows, the safety of your home increases. They are harder to break and are sealed tighter than other windows.

Less condensation – Double glazed windows reduce the amount of moisture on your window panes, as the airtight seal prevents the condensation from building up. Other windows often allow condensation to build up which causes window panes to have mould in.

Less noise – With more units comes less noise and a quieter home. If you live by busy roads or in a generally noisy area then double glazed windows are crucial to you
