A population of birds eats nuts and seeds. Some birds have larger beaks, and some have smaller beaks. A pair of birds usually produces four or five offspring each year. After several yeaers of little rain, the seeds became larger and larger. The birds with larger beaks were better at cracking these seeds. After several generations, the average beak size in the population increased. Bird beak size increasing after several generations is: a. decent with modification. b. variation. c. overproduction. d. adaptation

Answers

Answer 1

As far as I can tell, the answer would be D. Adaptation. The birds are evolving to adapt to their environment, and as such, their beaks are getting larger to crack larger seeds.

Using the concepts of chain of custody it is important to (multiple answer) A. document everyone who has handled the evidence prior to a trial B. record the dates and times of the possession of the evidence C. have a complete inventory of the evidence D. weight all of the evidence E. seal all of the evidence in air tight bags

Answers

Answer:

A. document everyone who has handled the evidence prior to a trial

Explanation:

A chain of custody can be defined as a paper trail containing the chronological order of items of evidence and how they have been handled, controlled, transferred, analyzed, and disposed during the investigation of a case.

This ultimately implies that, a chain of custody contains all the details or informations regarding the investigators (people) who handled, controlled, transferred, analyzed, and disposed an evidence in the course of carrying out investigations on a particular case. The most important and significant part of an investigation is the evidence because it helps to unravel the truth and facts relating to a case. Therefore, it is very important and essential to document and maintain a chain of custody so as to preserve the evidence.

Hence, using the concepts of chain of custody it is important to document everyone who has handled the evidence prior to a trial.

1. What percentage of puppies would have the same genotype as the
parents, Ww?

Answers

Answer:

50%

Explanation:

This question involves a single gene with two alleles W and w in puppies. According to the question, the genotype of the parent organisms are Ww. In a cross between the two parents i.e. Ww × Ww, the following gametes will be produced by each parent: W and w.

Using these gametes in a punnet square (see attached image), the following genotype of offsprings will be produced: WW, Ww, Ww, ww. Hence, based on this question, the percentage of puppies that would have the same genotype as the parents, Ww are 1/2 × 100% = 50%.

The people with AB+ blood group are called as the universal receivers. They can safely receive a blood transfusion using any other blood type. Having a universal blood type can save a life of yours or someone else in an emergency.

If you have an AB+ blood type, you have both A and B antigens. Since a person has all of the antigens that are possible, this blood type is the rarest. The AB+ blood type has a positive Rh factor, the recipient will not reject the blood. So it can get any type of blood.

AB type blood has no antibodies against type A or type B blood. So a person with AB blood can receive any type of blood.

Thus the correct option is A.
