Tibetans' physiological adaptations make them less likely to suffer from pulmonary hypertension (or high blood pressure). So, the correct option is C.
What do you mean by Adaptations?
Adaptations may be defined as the evolutionary process where an organism becomes better suited to its habitat, in order to survive and reproduce in it.
Tibetans are adapted to high altitudes by producing fewer red blood cells. They have greater hypoxic and hypercapnic ventilatory responsiveness. They have large lungs, and greater lung diffusing capacity. This leads them less likely to suffer from pulmonary hypertension.
Therefore, Tibetans' physiological adaptations make them less likely to suffer from pulmonary hypertension (or high blood pressure).

Comprehensive detail and links between structure and functions of cells and different tissue in animals
The main diffrence between their tissue is
1.Plant structure is different from the animal skeletal structure. A plant tissue is different from those in animals. Plant tissues are basically divided into two: Meristematic tissue and Permanent tissue.
Meristematic tissue: These tissues comprise of cells which have the dividing capacity. They are immature and help plants to divide continuously throughout the life. Depending on the site of location, it is of three types. Apical, lateral and intercalary meristems. These meristems enlarge the cell and increase the length and width of the stem, roots and leaves.
Permanent tissue: Permanent tissues are derivative of meristematic tissue. They don’t have the dividing capability but aid in other functions like conduction of substances, storage of food etc. Two types of permanent tissues are found in plants i.e. simple and complex permanent tissue. Simple permanent tissues include parenchyma, collenchyma and sclerenchyma while complex tissues are xylem and phloem.
Animal body is made of four different types of tissues.
Epithelial Tissue
Muscle Tissue
Connective Tissue
Nerve Tissue
Epithelial Tissue: All organs in the body are lined with a group of tissues called epithelial tissues. They cover the surface of all internal as well as external organs. There are four types of epithelial tissues: Squamous epithelium, Stratified epithelium, Cuboidal epithelium and Columnar epithelium. They may be cuboidal, columnar or even flat. The main functions of these tissues involve protection, secretion, absorption, sensation etc..
Muscle Tissue: This type of tissue forms three types of muscles, namely skeletal (striated or voluntary) muscle, smooth (unstriated or involuntary) muscle and cardiac (heart) muscle. They help in movement by contraction and relaxation of muscles.
Connective Tissue: As the name suggests, they connect the different tissues, organs and parts of the body. Different types of connective tissues are Areolar tissue, Adipose tissue (fat), Blood, Lymph, Bone and Cartilage. They connect and support organs and also transport substances between organs.
Nervous Tissue: These tissues are made up of specialised cells called nerve cells (neurons). They conduct and transmit electrochemical impulses between neurons.

Two dogs–a boxer and a poodle–were the first to have their entire genomes sequenced. The dog genome contains 2.8 billion2.8 billion base pairs across 3939 pairs of chromosomes. They have 19,00019,000 protein-coding genes, most of them with close counterparts in other mammals, including humans. What is the total number of chromosomes in a dog?
Answer:
78 chromosomes
Explanation:
Since the number of chromosomes in a dog are diploid, we have 2n chromosomes where n = number of chromosome pairs.
Since n = 39.
The number of chromosomes is 2n = 2 × 39 = 78 chromosomes
So, a dog has 78 chromosomes.

Dakota lives in New Orleans. He knows that scientists have predicted some changes on Earth due to global warming, and he is concerned it will affect his city.
What effects are scientists concerned about in relation to global warming? Choose the two that apply.
A. decreases in temperatures
B. melting of sea ice
C. decreasing sea levels
D. decreases of greenhouse gas concentrations
E. increase in carbon dioxide from melting permafrost
Melting of sea ice and increase in carbon dioxide from melting frozen grounds are effects scientists concern about in relation to global warming. Therefore, option (B) and (E) are correct.
What is global warming?Long-term changes in temperature and weather patterns are referred to as climate change. Although these changes may be natural, human actions have been the primary cause of climate change since the 1800s, mostly as a result of the burning of fossil fuels (such as coal, oil, and gas), which results in the production of heat-trapping gases.
Sea ice loss will expose the cold, dark Arctic water, which will absorb heat instead of reflecting it, accelerating the rate of global warming. Additionally, it will disrupt the ecology of the area, hurting everything from algae to sizable creatures like polar bears and seals that depend on the sea ice for hunting.

Nonvascular plants have never evolved to the size of vascular plants, most likely because they lack Select one: a. a photosynthetic mechanism. b. an efficient mode of respiration. c. an efficient system for conducting water and minerals. d. nutrient and water absorption mechanisms. e. They lack all of these choices.
Answer:
The correct answer is c. an efficient system for conducting water and minerals.
Explanation:
Non-vascular plants lack the internal tubes or vessels that carry water and minerals or nutrients through the entire plant. Most of them are found in humid or submerged places, since this type of environment allows them to absorb water through the surface of their tissues. Non-vascular plants do not grow very tall due to the lack of structures normally associated with vascular plants. Non-vascular plants lack specialized vascular tissue (xylem and phloem) for conduction and internal support of water and food. Metabolites and other nutrients are transferred between and within cells by osmosis, diffusion, and cytoplasmic flow.
Which will most likely happen if the decomposers are removed from the carbon cycle?

The thin, yellowish milk secreted in the few days right after birth is rich in antibodies and immune system cells. Group of answer choices True False
Answer: The statement is TRUE.
Explanation:
The thin, yellowish milk which may appear at any time from late pregnancy to few days right after birth is known as Colostrum milk.
During pregnancy, progesterone and oestrogen cause the milk glands to develop in the mother's breast. Immediately after birth, the anterior lobe of the pituitary releases a hormone, prolactin, which stimulates milk production. When the baby suckles at the mother's nipples, the milk flows out.
This first yellowish milk known as colostrum, contains all the essential nutrients that a newly born baby needs. It also provides antibodies and immune cells that protect the infant from disease. The milk is rich in protein and fats than normal milk. It is the first immune system defense they receive after birth. Therefore the above statement about the first thin yellowish milk is TRUE.

Briefly explain why DNA replication is semiconservative and discontinuous. Make sure to name the proteins involved in the synthesis of DNA, synthesis of RNA, the removal of RNA and the sealing of the nicks.
Answer:
DNA replication is semiconservative: each new strand has a strand of the parent DNA and another strand of new synthesis. DNA synthesis is discontinuous, since one of the strands, the lagging strand, replicates intermittently within the replication bubble, while the leading strand replicates continuously. For replication, apart from DNA polymerases, requires the action of enzymes that synthesize the primer, DNA ligases, enzymes that are responsible for joining pieces formed of chains, etc. RNA is synthesized through a process called transcription in making a complementary copy of a piece of DNA.
Explanation:
Replication is discontinuous since one of the strands, the lagging strand, replicates intermittently within the replication bubble, while the leading strand replicates continuously. It is bi-directional, because the strand is copied in both directions, and depending on the point of origin and the way it is viewed, a strand can be either discontinuous or continuous. Finally, replication is said to be semi-conservative since the original strands are part of each of the double strands resulting from replication.The unwinding of the DNA and the maintenance of the two separate strands in the replication fork so that the two new strands can be synthesized requires the action of proteins: Gyrase allows the release of the torque tension of the DNA double strand while the helicase separates the strands, allowing the action of DNA polymerases, which are responsible for the inclusion of new nucleotides as the DNA model strand is copied. Finally, the primases allow the incorporation of leader sequences at the beginning of the replication forks, allowing the action of DNA polymerases. DNA ligases seal cuts or nicks (broken phosphodiester bonds). DNA ligase also splices the ends of DNA into duplex regions. Transcription consists of the synthesis of RNA taking DNA as a template and means the passage of the information contained in DNA to RNA. The transfer of information from DNA to RNA is carried out following the complementary rules of the nitrogenous bases. When the entire strand has been copied, at the end of the process, the RNA chain is free and the DNA is closed again, by pairing of its complementary chains.
To get rid of waste generated by thousands of sailors aboard each of its aircraft carriers, the US Navy is using a process called pyrogenesis. In this process, waste is subjected to extraordinary heat. How is pyrogenesis different from the process of setting garbage on fire in a landfill
Answer:
Its location.
Explanation:
The main difference between pyrogenesis and setting garbage on fire in a landfill is that pyrogenesis process occurs on the surface whereas garbage on fire in a landfill occurs inside the soil at certain depth. Pyrogenesis is an extreme thermal process that converts organic matter into gas made up of hydrogen and oxygen whereas garbage on fire in a landfill decomposes garbage that breaks down materials in simpler substances.

Explain how demagnetizing a magnet (or temporary magnet) affects the domains.
Answer:
So, heating a magnet disrupts the domain walls and it becomes easy for the magnetic domains, which are ordinarily lined up, to rotate and become misaligned. They are now less aligned and point in the opposite direction to their neighbors, causing a decrease in the magnetic field and loss of magnetism.
