1.
Describe two advantages of genetic engineering.

Answers

Answer 1

Answer: One advantage of genetic engineering is the production of valuable proteins: recombinant DNA made possible the use of bacteria to produce proteins of medical importance such as genetically engineered human insulin which is of great importance.
Another advantage is the production of vaccines. Vaccines produced by genetic engineering offer an advantage that the microbial strains from which proteins are extracted do not contain complete viruses and thus there is no risk of accidental inoculation with live virus.

Farmer Brown grows corn for a living. One day, Farmer Green suggests to Farmer Brown that he should clone his best corn plant in order to produce more ears of corn per plant. Farmer Brown is not sure about Farmer Green's idea. Why might Farmer Brown be hesitant to clone his corn?
Beetle pollinators of a particular plant are attracted to its flowers' bright orange color. The beetles not only pollinate the flowers but mate while inside of the flowers. A mutant version of the plant with red flowers becomes more common with the passage of time. A particular variant of the beetle prefers the red flowers to the orange flowers. Over time, these two beetle variants diverge from each other to such an extent that interbreeding is no longer possible. What kind of speciation has occurred in this example, and what has driven it? A. Allopatric speciation, ecological isolation.B. Sympatric speciation, habitat differentiation.C. Allopatric speciation, behavioral isolation.D. Sympatric speciation, sexual selection.E.

When energy changes form, some energy is?

TRUTH OR FALSE10. nucleotides made of nucleic acids
4. Proteins are quick source of energy
1. All biochemical compounds contain carbon, hydrogen, and oxygen

Answers

Final answer:

Nucleotides are made of nucleic acids, proteins are not a quick source of energy, and not all biochemical compounds contain carbon, hydrogen, and oxygen.

Explanation:

True or False:

Nucleotides are made of nucleic acids. True. Nucleotides are the building blocks of nucleic acids, which include DNA and RNA. They consist of a sugar molecule, a phosphate group, and a nitrogenous base.
Proteins are a quick source of energy. False. While proteins are an important component of a balanced diet, they are not the preferred source of energy. Carbohydrates and fats are the primary sources of energy in the body.
All biochemical compounds contain carbon, hydrogen, and oxygen. False. While many biochemical compounds contain carbon, hydrogen, and oxygen, there are exceptions. For example, nucleic acids, which include DNA and RNA, also contain nitrogen and phosphorus.

. In fruit flies, normal wings are dominant and short wings are recessive. Construct a Punnett square wherein both parents are heterozygous for normal wings. Which of the following is the correct genotypic ratio for the F1 generation of this cross?25% of the offspring are homozygous for normal wings. 50% of the offspring are heterozygous for normal wings. 25% of the offspring are homozygous recessive for short wings.
75% of the offspring have normal wings, and 25% of the offspring have short wings.
50% of the offspring are heterozygous for normal wings. 50% of the offspring are homozygous recessive for short wings.
75% of the offspring are heterozygous for normal wings. 25% of the offspring are homozygous recessive for short wings.

Answers

Answer:

25% of the offspring are homozygous for normal wings. 50% of the offspring are heterozygous for normal wings. 25% of the offspring are homozygous recessive for short wings.

Explanation:

Let dominant allele be A and recessive allele be a

Parent 1: heterozygous normal wings = Aa

Parent 2: heterozygous normal wings = Aa

Parent 1 X Parent 2 :

A a

A AA Aa

a Aa aa

Genotype of progeny will be as follows:

1/4 or 25% = AA = homozygous dominant for normal wings

1/2 or 50% = Aa = heterozygous normal wings

1/4 or 25% = aa = homozygous recessive for short wings

Normal wings = WW
Short wings = ww

The Parents = Ww x Ww

A. 25% are homozygous dominate, 50% are heterozygous, 25% are homozygous recessive.

A controlled experiment is the testing of a hypothesis in duplicate with only one factor being different. True. False.

Answers

A controlled experiment is a type of experiment where we're testing one hypothesis in duplicate and we have only one different factor. This indeed is true. An example of an uncontrolled experiment would be where we would have many different types of variables which would possibly affect the result of our experiment for example.

Cephalopods such as squid and octopi can communicate by changing skin colors and sometimes even skin patterns. this type of communication is an example of a a chemical signal
b. sound signal
c. language
d. visual signal

Answers

This is an example of d. visual signal

It is not a language per se, and it is certainly not a sound signal. A chemical signal would be if they released chemicals from their body.

Answer:

d. visual signal

Explanation:

Changing color by cephalopods ssuch as squid & octopi is a type of visual signal which helps in communication. These creatures are highly social animals and for social behavior communication is a must. So, in order to communicate effectively, they often change the colors and patterns of their skin. Initially this ability to change color was meant for camouflage but later on these animals started using this ability to communicate. The control centre of such visual signals is their brain which can manipulate thechromatophores within their body. They usually use such visual signals during courtship rituals and hunting.
