The synaptonemal complex is Group of answer choices a network of microtubules that forms the spindle apparatus. a region of high
DerKrebs [107]

Answer:

a network of proteins that holds homologues together.

Explanation:

Genetics can be defined as the scientific study of hereditary in living organisms such as humans, animals and plants.

The synaptonemal complex is a network of proteins that holds homologues (homologous chromosomes) together.

Generally, a synaptonemal complex (protein lattice) is formed between homologous chromosomes during mitosis and meiosis. Also, synaptonemal complex is important for the formation of the four sister chromatids referred to as tetrads.

Furthermore, the synaptonemal complex (protein lattice) has a tripartite structure which comprises of the following components;

I. SC protein-1 (SYCP1).

II. SC protein-2 (SYCP2).

III. SC protein-3 (SYCP3).

In conclusion, the synaptonemal complex plays a significant role in synapsis, recombination and chromosome pairing.

In a certain species of plant, the allele to produce green melons (G) is dominant over the allele to produce yellow melons (g).
marishachu [46]

Answer:

4.26

Explanation:

Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.

                                Observed(o)   Expected(e)   (o-e)    $(o-e)^2$      $(o-e)^2/e$

Green-melon plant        53                    47               6          36             0.766

Yellow-melon plant        41                    47              -6          36             0.766

Therefore the chi-square value is 1.53 which is less than the critical value of 3.84. Therefore, the null hypothesis is accepted.

What plausible causal channel(s) runs directly from the treatment to the outcome?
IrinaVladis [17]
A high-interest rate means the opportunity cost to built or buy a house is high it is a possible channel. So when the interest rate is higher, there may be fewer new housing starts. The abstract point-scoring task requires a minimal model that illustrates a plausible causal channel.
