During recombination ________________________.
Sonbull [250]

Answer:

2)chiasmata hold chromosomes together.

Explanation:

Chiasma (pl. Chiasmata): it is the point of contact, the physical union between two non-sister chromatids that belong to homologous chromosomes. In a given chiasma, an exchange of genetic material can occur between both chromatids.

1) is FALSE becasue recombination occurs between chromatids of homologous chromosomes, NOT between sister chromatids.

3) is FALSE because more than one recombination event can occur in a given pair of homologous chromosomes.

4) is FALSE becasue synaptonemal complex keeps homologous chromosomes together, NOT sister chromatids. Additionally, recombination occurs in prophase 1, long before anaphase 2.

I’m confused help me pls
luda_lava [24]

Claim: This process uses expensive fertilizers and pesticides to grow pest free crops which may be produced in excess. Explain the reasons why people would go against growing wheat this way.

Your answer: Here are 3 reasons that go against growing wheat this way.

1. The fertilizers and pesticides are expensive and cost farmers a lot which takes away from the revenue that farmers make from growing the crops in the first place.

2. Other then fertilizers and Pesticides its a lot of work as you can see on the chart throughout the year there are many things you must do too keep crops bug free and pest free this reason I'm explaining says that taking and doing all of this work for not pests/bugs is too much and not needed.

3. Fungicide Is needed a lot and incredibly expensive when you used/spray it on crops that much and point goes a lot more for large crops too.

If these reasons don't work, find factors that or counterclaims that go against this method of harvesting wheat. (This is what your supposed too do)

Aneli [31]
<span>The S strain of bacteria that Griffith used was virulent meaning that when injected into the mouse, the mouse would die from pneumonia The R strain was nonvirulent and did not result in the death of the mouse. When Griffith injected mice with a dead S strain of pneumatic bacteria the mice remained healthy.

I hope this helps!
