Explanation:
1. DNA
2.A , G , C and T
3.The 3-dimensional double helix structure of DNA, correctly elucidated by James Watson and Francis Crick. Complementary bases are held together as a pair by hydrogen bonds.
4.Chargaff's realization that A = T and C = G, combined with some crucially important X-ray crystallography work by English researchers Rosalind Franklin and Maurice Wilkins, contributed to Watson and Crick's derivation of the three-dimensional, double-helical model for the structure of DNA.
5.Created by Rosalind Franklin using a technique called X-ray crystallography, it revealed the helical shape of the DNA molecule. Watson and Crick realized that DNA was made up of two chains of nucleotide pairs that encode the genetic information for all living things.
6. 1869
7.The double helix of DNA is, like its name implies, in the shape of a helix which is essentially a three dimensional spiral. The double comes from the fact that the helix is made of two long strands of DNA that are intertwined—sort of like a twisted ladder.
8. In DNA, the code letters are A, T, G, and C, which stand for the chemicals adenine, thymine, guanine, and cytosine, respectively. In base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine.
9. A gene is the basic physical and functional unit of heredity. Genes are made up of DNA. Some genes act as instructions to make molecules called proteins. ... Every person has two copies of each gene, one inherited from each parent.
10. 20
11. A group of disorders that cause red blood cells to become misshapen and break down.
With sickle cell disease, an inherited group of disorders, red blood cells contort into a sickle shape. The cells die early, leaving a shortage of healthy red blood cells (sickle cell anaemia) and can block blood flow causing pain (sickle cell crisis).
12. Sickle cell anemia is caused by a mutation in the gene that tells your body to make the iron-rich compound that makes blood red and enables red blood cells to carry oxygen from your lungs throughout your body (hemoglobin).
13. The Human Genome Project was an international scientific research project with the goal of determining the base pairs that make up human DNA, and of identifying and mapping all of the genes of the human genome from both a physical and a functional standpoint.

(20 POINTS!!) Respiration is a process where many chemical bonds inside the body break and release energy. This energy is used to perform various activities such as moving muscles. Explain the energy transformation in this process.
A. Chemical energy from broken bonds is transformed into mechanical energy for muscles.
B. Mechanical energy from broken bonds is transformed into chemical energy for muscles.
C. Mechanical energy from broken bonds is transformed into electrical energy for muscles.
D. Heat energy from broken bonds is transformed into electrical energy for muscles.
Answer:Cellular respiration is the process of transforming chemical energy into forms usable by the cell or organism. Organisms ingest organic molecules like the carbohydrate glucose to obtain the energy needed for cellular functions. The energy in glucose can be extracted in a series of chemical reactions known as cellular respiration. Most energy is produced during cellular respiration in the mitochondria, a process that involves breakdown of simple sugars to produce energy in the form of ATP, which is the usable form by the cell.

Some years ago, before crude oil prices became an economic concern and an international political issue, a biologist proposed a curious-sounding plan. He suggested that a portion of our crude oil supplies be converted directly into edible food, instead of distilling it to gasoline for the typical farming methods for raising food.
Before you become nauseated at the idea, you should know that this conversion has been done on a trial basis. Making edible, non-toxic food from petroleum is feasible. Also, considering that the components of fossil fuels were once ordinary plants and animals in an ordinary food chain, maybe there is some logic in his plan. What does crude oil amount to, anyway, but dinosaur fat? (No, really it is primarily formed from microscopic organisms.)
It might be the right time to form a new corporation and market a new product. What shall we call it…”DinoSnack,” maybe? With interest in dinosaurs as high as it is, how can we go wrong?
Your task is to evaluate this suggestion, allowing for both pro and con, the positive and the negative aspects of it. Surely there will be economic and political considerations, but concentrate especially on the biological, ecological factors.

What is the solution to the equation log2 (3x − 4) = 5?
Answer:
The correct answer is - 12.
Explanation:
Given:
log2 (3x − 4) = 5
Solution:
log2 (3x − 4) = 5
3x-4 = 2^5 (∵ lognx = b ⇔ x = a^b)
3x - 4 = 32
3x = 32+4
3x= 36
x= 36/3
x = 12

Answer: True
Explanation:
The statement that "In the beginning, man was born from creatures of a different kind; because other creatures are soon self-supporting, but man alone needs prolonged nursing" is true.
The creatures that were different from man became self supporting soon. If the present form had been the original form of man, he won't have survived.

a. epigenetic inheritance.
b. maternal effect.
c. sex-linked inheritance.
d. extra nuclear inheritance.
e. epistasis.
Answer:
Explanation:
Epigenetic inheritance is deals with the
study of the chemical modification of some genes or gene that are associated with proteins of an organism. An example of epigenetic is
Methylation it can either change rapidly during the life span of an organism or can be permanent if set early in the development of the embryo.
Epigenetic modifications are heritable, and can be passed from parents to offspring through genetic inheritance or passed down through multiple generations via transgenerational epigenetic inheritance.
An experiment similar to the 1952 Hershey and Chase experiments was done in which radioisotope 35S was added to a bacteriophage replicating within its bacterial host. The new phage particles were carefully isolated and used to infect fresh bacterial cells and no radioisotopes were utilized. Based on this information, where would you expect to find the 35S radioisotope immediately after infection
Answer:
inside the phage ghosts outside the bacterial cells.
Explanation:
According to Hershey & Chase- Experiments, the radioisotope 35S is frequently associated with protein since sulfur is a protein component. The radioactive sulfur is absorbed into the protein coat because it already contained sulfur (35S). The radioactive marker 35S was integrated into the Bacteriophage protein coat and remained as phage ghosts outside the bacterial cells.

Answer:
r-selected species (e.g., American bullfrog)
Explanation:
The r-selected species (r-strategists) are those species in which their populations oscillate near the carrying capacity, i.e., the maximum population size sustained by a particular environment. These species are generally located in low-quality (less competitive) ecological niches and produce many offsprings that grow rapidly and have low chances of surviving to adulthood. Some examples of r-strategists include amphibians, fish, small mammals, etc. Conversely, K-selected species have more stable populations and produce a low amount of offspring (e.g., large mammals such as elephants).

What are two ways in which ultrasound technology produces images?

B. By detecting the frequencies of emitted sound waves
C. By using sound in frequencies that reflect off body tissues
D. By measuring the time it takes for reflected sound waves to be
detected
C and D
Hope this helps have a great day!!
The ultrasound images are produced by using the sound frequencies that reflect off body tissues and by measuring the time it takes for reflected sound waves to be detected. So the correct options are C and D.
What is ultrasound imaging?High-frequency sound waves are used in ultrasound imaging, also known as sonography, to look within the body.
Real-time ultrasound imaging allows for the display of blood flowing via blood vessels as well as the activity of the body's interior organs.
Contrary to X-ray imaging, ultrasonic imaging does not expose patients to ionizing radiation. A transducer (probe) is positioned either on the skin or within a bodily orifice during an ultrasonic examination.
To allow the ultrasonic waves from the transducer to pass through the gel and into the body, a small coating of gel is placed on the skin.
The ultrasound picture is created as a result of the waves' reflection off the body's structures. The information required to create a picture is provided by the intensity (amplitude) of the acoustic signals and the duration of the wave's passage through the body. Therefore the correct options are C and D.
