Answer:

DNA binding domain and allosteric domain

Explanation:

Repressors are proteins that inhibit gene expression, They usually have DNA or RNA binding site which enables them to binde to the operator or associated silencers. Allosteric domain is the site for the binding of other molecules, such as  corepressors and inducers that regulate repressor's activity.

<h2>Blood is forced upward and toward</h2>

Explanation:

  • In the cardiovascular cycle, the autonomous withdrawal and unwinding of heart cells are facilitated through the movement of the heart's characteristic conduction framework and by cell-to-cell correspondence by means of the hole intersections in the myocardial cells themselves.  
  • The natural conduction arrangement of the heart comprises of nodal tissue, whose specific cells have both apprehensive and solid qualities. Nodal tissue is restricted in explicit areas of the heart.

A population is made up of individuals where 77 have the A1A1 genotype, 65 have the A1A2 genotype, and 123 have the A2A2 genotyp
lana [24]

Answer:

Frequency of allele A1- 0.41

Explanation:

In Hardy weinberg equilibrium,

P refers to the dominant allele

q refers to the recessive allele

The allele frequency will be p+q=1

The genotypic frequency is- P²+q²+2pq=1

P²= genotype of dominant trait ( A1A1)- 77

2pq= genotype of heterozygotes (2pq)- 65

q²= genotype of recessive trait (A2A2)-  123

Total number of offsprings= 77+  65+ 123

                                            = 265

Now to calculate allele frequency of A1=

\dfrac{\text{number of A1A1 offspring}}{ \text{total number of offspring}}+\dfrac{1}{2}(\dfrac{\text{number of A1A2 offspring}}{\text{total number of offspring}})

= 77/265 + 1/2( 65//265)

=  0.290+ 0.122

= 0.413

Thus, 0.41 is correct.

There is presense air sac in stem of free floating plant why?​
Vanyuwa [196]

Answer:

Since they need to float, leaves on the surface of plants are flat. 6. The presence of air sacs enables them to float. Their roots are smaller so water can spread freely and directly into the leaves
