Chromosomes often exchange segments of DNA during meiosis. How might this increase the survival of a species?

Answers

Answer 1

Answer:

Because of recombination and independent assortment in meiosis, each gamete contains a different set of DNA. This produces a unique combination of genes in the resulting zygote. Recombination or crossing over occurs during prophase

write a 5-7 sentence paragraph explaining what happens to co2 levels in the world over the course of the year. add as much context and details as you can

Answers

Answer:

The amount of CO2 found in the atmosphere varies over the course of a year. Much of this variation happens because of the role of plants in the carbon cycle. Respiration happens all the time, but dominates during the colder months of the year, resulting in higher CO2 levels in the atmosphere during those months.

why are manure better than fertilizers​

Answers

Manure is better than fertiliser. Manure is derived naturally and adds a lot more than just nutrients to the soil. They increase the activity of the microbes in the soil and increase its fertility. On the other hand, fertilisers harm these microbes and cause health issues in the consumers since they are synthesised chemically.

describe the structure of an atom of argon-38 and argon-40

Answers

Answer:

Argon 38 has 18 proton and 20 neutron

Argon 40 has 18 proton and 22 neutron

Explanation:

isotope is same no of proton diff no of neutron

Both argon-38 and argon-40 have 18 protons but they have different atomic masses. The atomic mass of argon-38 is 38u while the atomic mass of argon-40 is 40u. Thus, they are isotopes.

What are isotopes? Some atoms contain the same number of protons (i.e. same atomic number) but they have a different number of neutrons (i.e. different mass numbers). These types of atoms are called isotopes.Argon element has three isotopes namely, argon-36, argon-38 and argon-40. All the three isotopes of argon have the same number of protons i.e. 18. But, all have different numbers of neutrons and thus, different mass numbers. Argon-36 has 18 neutrons, argon-38 has 20 neutrons and argon-40 has 22 neutrons. Thus, the mass numbers of argon-36, argon-38 and argon-40 are 36u, 38u and 40u respectively.

Thus, the structure of an atom of argon-38 and argon-40 is slightly different as they are isotopes. Argon 40 has more atomic mass than argon-38. But, both contain the same number of protons. They have similar chemical properties but different physical properties.

Written by Katie Thompson-Chapter 3By the time we have managed to pull the now snoring unicorn out onto the driveway, the color in Joes face completely gone. HowWhereDid this thing come from? he asks, panting.What, afraid its real after all? I ask.He looks up at me and offers a half-smile. Who wants unicorns to be real if they look like that?I hide a laugh. WellNow we just have to figure out how to wake it up. I poke it a few times with my foot, trying to keep some distance. It just keeps snoring.Joe shrugs and bends down next to its ugly face and starts jiggling its shoulder, like hes trying to wake up a very old uncle.Suddenly its eyes open wide, and with an unbelievable grace, it stands upright. Joe jumps away to give it space, and I just keep staring at it. It walks over to the desert-style landscaping of my neighbors side yard and being perusing for its breakfast.That things a lot more agile than I imagined it would be, Joe says. We both stare at it as it saunters around, pulling up the grassy weeds from between the rock mulch. Sothats a unicorn.I look up at Joe and he's got this silly grin on his face. It's just so 'Joe' that I giggle. Do you believe that's what it is yet? I ask.I could if I wanted to, he replied.I looked up at him, questioning.That thing, he points to the unicorn. I could believe it was if I wanted to.The unicorn seems to have decided that it isnt going to find anything worth eating here and starts to walk down the sloping back yard to the next street. It looks almost like it belongs there, like a stray deer who often grazes around this part of town when no person is awake or watching. When it disappears from our sight, I feel like a ton of responsibility has been lifted from me.The whole morning seems almost trivial. Well, I say, I guess that is that?Joe shrugs, checks his watch, and motions toward the bus stop. We should get going, he says. I grab my bag, and we walk down the driveway.I don't know if that thing was a unicorn or not, he says, looking up into the sky like he might see a dragon flying around to confirm my claim. But I'm glad you called me this morning.Sorry I wasnot very nice, I say, hesitating.He laughs a little but keeps looking around. Then with a huge gulp of air, Do you believe we could be friends again? Like, real friends again? Because I gotta say, I really do miss you, Anna.I smile, remembering what he said earlier and reply, I believe we could if we wanted to.This time he looks over at me. And?And I really hope we want to.What is the main problem in this chapter of the story?a) Joe is completely uninterested in being friends with Anna again, but won't say why.b) When Joe asks Anna to be his friend, she becomes even more uncomfortable and says no. c) Even though she feels a little better, Anna still isn't sure what Joe is thinking about their friendship.d) The sleeping unicorn is very angry when it wakes up, and it starts ruining the neighbor's yard. please please help me I will mark brainlist !!
