Answer:

Threonine has two chiral centers.

The correct options are c. carbon b and d. carbon c

Explanation:

Chiral centers are those that have four different groups of atoms bonded to it. Carbon a has three atoms of hydrogen attached to it so it can't be a chiral carbon. It isn't the carboxyl carbon either since it is double bonded to oxygen. And the amino nitrogen does not qualify anyway because it is bonded to three different groups of atoms, not four.

Answer:

Este es un ejemplo de dominancia incompleta. Es una ocurrencia genética que ocurre cuando un gen dominante no expresa su manifestación completa en el alelo recesivo en un alelo dominante heterocigoto.

Por lo tanto, ambos rasgos se manifiestan, lo que resulta en la combinación de los dos alelos para los colores (blanco y rojo). Se dice que el alelo rojo dominante exhibe un dominio parcial sobre el alelo blanco recesivo, y esto da como resultado el alelo completamente rosado.

De acuerdo con la ley mendeliana, las dos flores rojas son heterocigóticas. Por lo tanto, las flores rojas heterocigóticas dominantes deben ser R. El alelo blanco es recesivo (rr) enmascarado por el rojo R,

Sin embargo, cuando se cruzan los dos alelos heterocigotos rojos:

Los fenotipos están en forma de

RR, (1) rojo Rr Rr (2) rosa rr (1) Blanco.

Esto ocurre porque el alelo rojo dominante no era total / completamente dominante en el alelo recesivo blanco en cada uno, lo que da como resultado un alelo rosa (el tercer fenotipo)

This is an example of incomplete dominance.It is a genetic occurrence  which occurs when a dominant gene does not express it full manifestation on the recessive allele in an heterozygote dominant allele.

Therefore,both traits are manifested which results in the blend of the two allele for colors(white and red).The dominant red allele is said to exhibit partial dominance over the recessive white allele.And this results in the entirely pink allele.

Based on Mendelian law the  two red flowers are  heterozygotes .Therefore, Red heterozygote dominant flowers should beRr.The white allele is recessive(rr) masked by the R-red,

However,when the two red heterozygote alleles are crossed:

The phenotypes are in the form of  

RR,(1) red  Rr Rr(2) pink  rr(1)White.

This occurs because, the dominant red allele was not fully/completely  dominant on the  white recessive allele in each,which results in pink allele(The third phenotype)

Biological control methods for managing insect pests are effective for reasons that include which of the following? They promote
Semenov [28]

Answer:

Option B, They generally focus on one target insect to ensure that the target insect population remains low.

Explanation:

Biological pest control methodologies are focused towards a specific species of pest and do not harm the non-targeted species. These methods are environment friendly and do not produce any harmful residues. Also they do not develop any kind of resistance in species due to which the same bio pesticide can be used again and again. Since these methods have high specificity, they may require usage of two or more bio pesticides all together.  

Hence, option B is correct
