Your apple trees are growing well and producing healthy fruit in early summer, but your grape vines look wilted and have little

holes all over them. You also notice a preponderance of moth larvae and Japanese beetles have started to emerge. What could you do to protect your investment?

Answer:

Use pesticides.

Explanation:

I use pesticides to protect my grapes field because pests such as moth larvae and Japanese beetles etc attacked on my grapes field and to protect this field from further destruction, spray of pesticides is compulsory in order to kill the pests present on grapes. There are also some other methods such as mechanical and biological method to control the population of these pests in the field but these methods takes a lot of time to be effective.

A mutation creates a dominant negative allele of a particular gene. The normal allele of the gene encodes a protein that forms a
Wewaii [24]

Answer:

87.5% of the trimers in the cell will be inactive.

Explanation:

A monomer is a single subunit. Look at an easy comparison. If a monomer is a ball. For the protein to be functional, it needs to be a trimer .A trimer = 3 monomers joined / bound together with bonds. Therefore, if a monomer is a ball, we need 3 balls, we attach it together and that is the primer . if one ball becomes missing, that protein won't work .

In chemistry, a trimer is regarded as three molecules or ions of the same substance (that is, same type) which are associated together .

Double negative : Each gene has 2 alleles. So, for a positive protein, both allele needs to be same, let's say + means on. So for a x protein , if it's x+/x+ it means the protein is homozygous and active. If for some mutation, it's x+/x- , it's a heterozygous protein. Double negative means when it is x-/x- and this means the protein has lost is function . It's not functional at all.

The heterozygous cell will form one or more subunits has the mutant structure when the gene is expressed. From the question if there is a mutation in dominant negative allele, it will cause the inactivation of one trimer resulting in 87.5% inactive trimers for a heterozygous individual.

There are 87.5 % percent of the trimers present in the cell which will be inactive for a heterozygous individual, If at least one of the subunits has the mutant structure.

The probability for each individual subunit to be a mutant is 1/2

Gene codes for a protein that forms trimer so the percentage of the trimers present in the heterozygous individual is third power of 1/2 =1/8

1/8=0.125 will be active.

1- 0.125 will be inactive.

=0.875 will be inactive.

0.875 × 100= 87.5%

Therefore 87.5% will be inactive.

Alligators, crocodiles, and snakes are all reptiles. However, alligators are more closely related to snakes. Which statement MOS
Delvig [45]
Are there any statements given for this assignment? Because according to what I know, alligators and crocodiles are more related to birds because of archosaurian origins. However, crocodiles are more closely related to birds than snakes because the evolution of birds  from having snouts to beaks are slightly evident in crocodiles for they have more pointly snouts.
