For an ecological study, you monitor herbivore-plant interactions in a rainforest and notice that mammalian herbivores avoid the

leaves of a particular species of plant. However, a number of tiny herbivorous insect generalists that feed by piercing individual plant cells with their mouthparts appear capable of completing their entire life cycle feeding on this same species. You hypothesize that in this species the chemical defenses are: A. stored in the cytoplasm of epidermal leaf cells. B. stored in the vacuole in an inactive form and are activated by enzymes in the cytoplasm. C. nonexistent. D. contained in a latex stored in vascular canals.

Which of the following is TRUE about sexual reproduction? Please choose the correct answer from the following choices, and then
Marina CMI [18]

Answer:

The correct answer is A. Sexual reproduction produces a greater variation in offspring.

Explanation:

  • B is wrong because in sexual reproduction there are two organisms involved who combine their DNA, therefore resulting in non-identical offsprings.
  • C is wrong because sexual reproduction requires the two organisms involved to exchange DNA's whereas asexual reproduction involves only one organism which only copies it's own DNA for reproduction.
  • D is wrong because there are no risks as genetic defects and no need to seek a mate or it is easier than sexual reproduction which results in lower risks for the parents in asexual reproduction.
  • E is wrong because asexual production is a more efficient procedure and results in a faster growing population because there is no need to search a mate.
  • The answer is A because in sexual reproduction, two different DNA's from both parents get combined resulting in more variation in offspring. In asexual reproduction, there is only one set of DNA which does not allow the gene's to mix, causing a less diverse offspring.

Some regions of a polypeptide may coil or fold back on themselves. This is called _____, and the coils or folds are held in plac
zalisa [80]

Answer:

The options are

A. secondary structure ... hydrogen bonds

B. secondary structure ... peptide bonds

C. tertiary structure ... hydrogen bonds

D. primary structure ... covalent bonds

E. tertiary structure ... covalent bonds

THE CORRECT ANSWER IS A.

A. secondary structure ... hydrogen bonds

Explanation:

The secondary structure of a polypeptide shows the localized regions of its organised structure being upheld by hydrogen bonds among the major groups

-NH and C = O

At the same time, it inhibits the hydrogen bonds of the side chains from influencing the reaction process.

The polypeptide secondary structure shows the dexterity to curl or fold as sustained by the polypeptide chains.

To check whether Earnest and Denise could have a baby with Type O blood, draw a Punnett square for a father who has blood Type A
Nutka1998 [239]

Answer:

Answer is explained below and also see the document attached below for Punnett square.

Explanation:

ABO blood type (A, B, AB, or O) is based on the presence (or absence) of the A and B antigens in the red blood cells. The blood type, A has only the A antigen (and has anti-B antibodies) while the blood type, B has only the B antigen (and had anti-A antibodies). Also in the AB  blood type, both A and B antigens are present (but has no antibodies) while in the O blood type, both A and B antigens are absent (but has both antibodies).

The blood type is inherited from the parents and the offspring inherits one of the two alleles from each parent. The ABO blood type has three types of alleles: IA, IB, and i. Here, I is a term for antigen (isoagglutinogen).

The IA and IB alleles are dominant while the i allele is recessive. The blood type A is formed by either two IA alleles (IA IA ) or IA i. So, the genotype of blood type A is IA IA  or IA i. The blood type B is formed by either two IB alleles (IB IB ) or IB i. So, the genotype of blood type B is IB IB or IB i. The O blood type is formed only by two i alleles (ii). So, the genotype of blood type O is ii. The IA and IB alleles (IA IB) give the AB blood type, which is an example of codominance (the traits of both the alleles are visible in the phenotype). The genotype of blood type AB is IA IB.  

If the parents have blood type A and B, then they can have an AB blood type offspring. If the parents have blood type A and B and they both are heterozygous (IB i and IA i), then they can also have a O blood type child.

Here, the father has blood Type A (IA i genotype) while the mother has blood Type B (IB i genotype). Both the parents are heterozygous (IB i and IAi), so the possible genotypes of their child are IA IB (blood type AB), IA i (blood type A), IB i (blood type B) and ii (blood type O).

i.e.,            <u> Blood Type </u>                             <u>Genotype </u>

                           A                                     IA IA or IA i

                           B                                     IB IB or IB i

                          AB                                        IA IB

                           O                                            ii
