Of the choices below, which best describes the effect predation has on the predator/prey organisms involved in the relationship?
steposvetlana [31]

Answer:

The correct answer is C. benefit ... harmed

Explanation:

Predation is a type of interaction between two individuals in which one individual gets harmed which is called prey and another organism who is predator gets benefitted.

In predation, the predator kills its prey and consume it to survive. For example, Lion is a predator and deer is the prey so during predation lion kills the deer and consume it so here lions get benefited by consuming deer and deer is harmed as it lost its life. So the correct answer is C. benefit ... harmed.

Calculate the percentage ionization in these amino acid side chains at the ph values specified:
Margarita [4]

The <u>Henderson-Hasselbalch equation</u> and pKa can be used to determine the % ionization if it is assumed that the amino and carboxyl groups are not preventing ionization.

  1. aspartate at ph 5.4 = 98.3%
  2. glutamate at ph 11.8 = 100%
  3. histidine at ph 8.0 = 99%

Henderson-Hasselbalch equation- Henderson-Hasselbalch Equation to determine the pH of a solution. Knowing the pH of a solution is particularly significant for many chemical processes as well as for biological systems. The estimated pH value of a buffer solution may be determined using the Henderson-Hasselbalch equation.

pH- A solution's acidity or alkalinity may be determined based on the concentration of hydrogen ions in the solution, or pH. Typically, the pH scale runs from 0 to 14.

Ben Affleck has a cleft chin, but his ex-wife Jennifer Garner does not. Neither one of their two daughters (Violet and Seraphina
kherson [118]

Answer:

Ben - Y Xc

Jen - XCXC

Violet - XCXc

Seraphina - XCXc

Samuel- Y Xc

Explanation:

Given -

Ben has a cleft chin

Let the allele for cleft chin be "c"

and the allele for normal chin be "C"

When Ben with cleft chin mates with wife Jennifer Garner having normal chin, then the two girl child do not have cleft chin but the boy has cleft chin.

This means that the allele C could be X -linked and the mother is not the carrier but the father is

The genotype of father Ben would be Y Xc

Genotype of mother would be XCXC

Genotype of two daughters XCXc  , XCXc which means they are carrier for the next generation

Genotype of Boy - Y Xc
