True or false

Answer:

Explanation:

The DNA of an animal's somatic cell is transferred into an egg cell that has had its nucleus and DNA removed in order to create a clone. With the same genes as the cell donor, the egg develops into an embryo. The embryo is then placed inside the uterus of an adult female to develop.

A polymer made of two polynucleotide chains that coil around one another to form a double helix is called deoxyribonucleic acid. All known organisms and many viruses have genetic information in the polymer that is necessary for their development, operation, growth, and reproduction. Nucleic acids include DNA and ribonucleic acid.

The process of genetic engineering consists of three main phases. These include (1) isolating DNA fragments from a donor organism, (2) integrating an isolated donor DNA fragment into the genome of the vector, and (3) allowing the recombinant vector to develop in the proper host.

Selection, mutagenesis, conjugation, and protoplasm fusion are examples of conventional genetic modification techniques that have been used, particularly for microbial starter cultures. The latter is comparable to somatic hybridization in plant systems.

Thus, The DNA of an animal's somatic cell is transferred into an egg cell that has had its nucleus and DNA removed in order to create a clone.

Explanation:

The correct answer would be C "They were from all parts of the world."

Explanation:

As scientists analyze and interpret their data , they generate hypotheses, theories, or laws which help explain their results and place them in context of the larger body of scientific knowledge. These different kinds of explanations are tested by scientists through additional experiments, observations, modeling, and theoretical studies. Thus, the body of scientific knowledge builds on previous ideas and is constantly growing. It is deliberately shared with colleagues through the process of peer review , where scientists comment on each other's work, and then through publication in the scientific literature , where it can be evaluated and integrated into the body of scientific knowledge by the larger community. And this is not the end: One of the hallmarks of scientific knowledge is that it is subject to change, as new data are collected and reinterpretations of existing data are made. Major theories, which are supported by multiple lines of evidence, are rarely completely changed, but new data and tested explanations add nuance and detail.

Land that is not utilized for timber production or farming but supports various types of vegetation, such as shrublands, deserts, and grasslands, is referred to as rangelands. These are specific areas of land dedicated to grazing livestock and wildlife.

Rangelands are areas of land that are primarily used for grazing livestock and wildlife. They are characterized by a diverse range of vegetation types, including grasses, shrubs, and other herbaceous plants. Rangelands are typically unsuitable for intensive agricultural activities or timber production due to factors such as soil quality, climate, or topography.

These lands serve important ecological functions, such as providing habitats for wildlife, preserving biodiversity, and protecting soil and water resources. Rangelands are often managed to maintain a balance between sustainable livestock grazing and the conservation of natural ecosystems. They can be found in various regions around the world, including arid and semi-arid areas where agriculture is challenging.

Therefore, among the options provided, the term "rangelands" best describes land that is not utilized for timber production or farming but supports various types of vegetation, including shrublands, deserts, and grasslands.

Krypton 85 decays into rubidium 85 with a half-life of 10.76 years, which means that half of the initial krypton 85 atoms will decay into rubidium 85 in 10.76 years.

The radioactive decay of krypton 85 can be represented by the following equation:

Kr-85 → Rb-85 + β-

where β- represents an electron emitted in the decay process. Krypton 85 decays into rubidium 85 by emitting a beta particle.

The half-life of krypton 85 is 10.76 years, which means that half of the initial krypton 85 atoms will decay into rubidium 85 in 10.76 years.

\(N = \frac{N_{0}}{2^{t/T} }\)

where N is the current number of krypton 85 atoms, N0 is the initial number of krypton 85 atoms, t is the time elapsed, and T is the half-life of krypton 85.

In this case, we know that the initial number of krypton 85 atoms is 4, and the current number of krypton 85 atoms is 4/2 = 2. We also know that the sample contains 12 rubidium 85 atoms.

Therefore, we can use the above equation to find the time elapsed:

\(2 = \frac{4}{2^{t/10.76} }\)

\(2^{t/10.76} = 2\)

\(\frac{t}{10.76}\) = log2(2)

t = 10.76 years

A visible DNA fingerprint provides information about the unique genetic makeup of an individual by displaying a pattern of DNA fragments. This pattern is created through a process called gel electrophoresis, where the DNA samples are separated based on their size and charge. The resulting bands on the gel represent fragments of the DNA that have migrated through the gel. The pattern of the bands is unique to each individual and can be used for identification purposes. The visible DNA fingerprint allows scientists to compare different DNA samples, such as those from a crime scene or paternity testing, and determine if they come from the same individual or not.

The breaststroke is not started in the dive position in the water. Therefore, the statement is false.

The breaststroke is not started in the dive position in the water. It started in a stationary position with the swimmer, which faces forward and floats in the water.

The swimmer then takes a breath followed by the beginning of the stroke by pulling both arms back simultaneously and lifting their head and shoulders out of the water.

The legs are brought together by the swimmer andglides forward before the repetition of the arm and leg movements. It is the butterfly stroke because of the dive position, as the swimmer resurfaces both arms extended above the head to begin the stroke.

If the surface area of a cube is increased by a factor of 2, the volume per unit area of the cube would change by a factor of 1/2 or 0.5. To understand this, let's consider the relationship between the surface area and volume of a cube.

The surface area of a cube is given by 6s^2, where s is the length of one side of the cube. The volume of the cube is given by s^3. If we increase the surface area by a factor of 2, the new surface area would be 2 times the original surface area: 2 * 6s^2 = 12s^2. Now, let's calculate the volume per unit area, which is the volume divided by the surface area. The original volume per unit area is (s^3) / (6s^2) = s/6. When the surface area is increased by a factor of 2, the new volume per unit area becomes (s^3) / (12s^2) = s/12. Comparing the new volume per unit area (s/12) to the original volume per unit area (s/6), we find that the ratio is 1/2 or 0.5. Therefore, the volume per unit area of the cube changes by a factor of 0.5 when the surface area is increased by a factor of 2.

transcription, DNA is made into a molecule of RNA which will travel to the ?PROTEIN SITE?

in the cytoplasm, Here, three bases, called a CODON, will determine what acid is added to the chain. This chain will fold into a TERTIARY STRUCTURE.

Explanation:

I'm not too sure about "protein site," but I hope the rest helps!

Answer:

DNA is composed of sugar, phosphate and four nitrogen bases (A, T, G, C). During transcription, DNA is made into a molecule of RNA, which will travel to the ribosomes in the cytoplasm. Here, three bases, called a codon, will determine what amino acid is added to the chain. This chain will fold into a protein. This shape of this molecule determines how it functions.

Changes in the DNA code are called mutation and they can cause a protein to not function properly. A single change in the DNA of the hemoglobin gene will cause sickle cell anemia.

Explanation:

Adenine (A), Cytosine (C), Guanine (G), and Thymine are nitrogen bases. A and T pair together while C and G pair together. In DNA/RNA pairings, A pairs with Uracil (U). Transcription happens in the RNA, which is sent from the nucleus to the ribosomes (where protein is made). The three bases are called codon, their three base pairing is called an anticodon.

DNA gets mutated and this causes changes in the code. Sickle cell anemia occurs in the hemoglobin.

Explanation:

Viviparity is a reproductive process in which embryos develop inside the mother, receive nourishment from her, and are eventually born as live offspring. The process involves several steps:

1. Fertilization: The male sperm fertilizes the female egg, and the zygote is formed.

2. Implantation: The zygote implants itself in the wall of the mother's uterus, where it begins to develop.

3. Placenta formation: The placenta, which is a specialized organ that connects the embryo to the mother's circulatory system, forms. This allows the embryo to receive nutrients and oxygen from the mother and eliminate waste products.

4. Embryonic development: The embryo develops inside the mother, growing and developing its organs and tissues.

5. Birth: When the embryo has fully developed, it is born as a live offspring, usually through the mother's vaginal canal.

Overall, the process of viviparity allows for greater protection and development of offspring, as they can receive direct nourishment and protection from their mother during their development.

Viviparity is a reproductive process in which offspring develop and are nourished within the mother's body until they are capable of independent survival.
It is commonly observed in mammals, including humans.

Here is an explanation of the process:

After birth, the baby continues to rely on the mother or other external sources for nourishment and care until it becomes self-sufficient.
Viviparity is different than oviparity, where embryos develop outside the mother's body, typically inside eggs laid by the mother.

Obstructive Disorders:
- Decreased airflow by bronchoconstriction
- Heavy smokers
- Asthma
- Bronchitis

Restrictive Disorders:
- Tuberculosis
- Neuromuscular disorders
- Weakening of respiratory muscles
- Fibrosis caused by coal dust

Obstructive lung disorders are characterized by a decreased airflow due to partial or complete obstruction of the airways. The obstructive disorders listed in the question are asthma, bronchitis, decreased airflow by bronchoconstriction (as seen in conditions like chronic obstructive pulmonary disease, or COPD), and heavy smokers. In these conditions, the airways become narrow and obstructed, making it difficult for air to flow in and out of the lungs, leading to symptoms like wheezing, coughing, and shortness of breath.

On the other hand, restrictive lung disorders are characterized by a decrease in lung volume due to stiffness or restriction of the lung tissue itself, the chest wall, or the respiratory muscles. The restrictive disorders listed in the question are neuromuscular disorders (such as muscular dystrophy or amyotrophic lateral sclerosis), fibrosis caused by coal dust (as seen in pneumoconiosis), and weakening of respiratory muscles (as seen in conditions like myasthenia gravis). In these conditions, the lungs are unable to expand fully, leading to reduced lung volumes and difficulty breathing.

Splanchnic and viscera both refer to internal organs. Thus the correct answer is option (A). splanchnic and viscera.

The splanchnic nerves supply efferent and afferent fibers to the viscera of the bodily cavities. The larynx, trachea, bronchi, and lungs are the targets of the cardiopulmonary splanchnic nerves, which run from C4 to T5. Abdominopelvic splanchnic nerves transmit presynaptic sympathetic fibers from the viscera of the abdominal cavity (stomach and intestines) to the prevertebral ganglia. Preganglionic splanchnic neurons from the thoracic sympathetic chains travel down the diaphragm and connect with preaortic (prevertebral) ganglia in relation to the sympathetic innervation of the abdomen. If existent, the lesser splanchnic nerve, originating from T10-T11 segments, terminates on the celiac or aorticorenal ganglia, whereas the least (lowest) splanchnic nerve, emanating from T12, does so as well. The bigger splanchnic (visceral) nerve is made up of the T5 to T9 segments, which come to an end on the celiac gangli. In 4% of cases, a fourth or auxiliary splanchnic nerve with the same terminal and path as the least splanchnic nerve can be identified.
