Physiologically, exercise increases blood flow and activates the sympathetic nervous system.

Exercise is any skeletal muscle-generated motion that requires an energy expenditure. All movement is seen as physical exercise, whether it is done for fun, to go to and from places, or as part of a person's employment.

Exercise activates the sympathetic nervous system, which then triggers a coordinated response from the body to maintain a healthy level of homeostasis despite the increased strain imposed on one's physical, metabolic, respiratory, and cardiovascular systems. The heart becomes stronger with regular exercise. A heart that is stronger could be able to pump blood more efficiently. The arteries are under less pressure as a result. Blood pressure drops as a result.

Answer:

B. A feature or behavior that helps an animal survive in its environment.

Answer:

If there would be no biosphere on earth the atmosphere would be quite different. There would be no oxygen to support because oxygen is liberated by plants in photosynthesis so no plants means no oxygen. The earth would be a planet without life just like Venus and Mars. Therefore, no organism would be surviving in the world.

There would be no  negligible green house effect and global warming since it is all created due to activities of men.The earth's atmosphere would be much cleaner and with lesser amount of CO2 and O2 but no organism would be there to use them.

Hope it help!

There would be more carbon dioxide, which would eventually burn away the ozone layer, as well as no oxygen, and all animal and plant life would perish.

The biosphere is basically comprised up of the areas of the Earth where life can be found.

The biosphere encompasses all the things from the deepest tree root systems to the dark environment of ocean trenches, including lush rainforests, and high mountaintops. Earth is described by scientists in terms of spheres.

Because it is all of life, the biosphere is as important as life itself. Earth would be a lifeless planet like Mars or Venus without the biosphere. Human insecurity grows as natural resources are depleted.

The biosphere is the zone that contains all living things. The biosphere requires the lithosphere, hydrosphere, and atmosphere to exist. There would be no life on Earth if these three spheres did not exist.

Thus, this way, the atmosphere would be impacted in the absence of the biosphere.

Single-celled organisms that cause a variety of diseases in animals, plants, and humans; they may also produce extremely potent toxins inside the human body. The four types of bacteria that will be discussed are anthrax, plague, tularemia, and Query (Q) fever. Anthrax is a bacteria that infects animals, particularly cattle and sheep. It is also a disease that affects humans. In humans, anthrax can be acquired through contact with animals or animal products that have been infected with the bacteria. Ingestion or inhalation of spores is also another way that the bacteria can be acquired.

The anthrax bacterium produces spores that can live for decades, and as a result, the bacteria is a significant biothreat agent.Pneumonic plague is the most severe form of the disease caused by the bacteria Yersinia pestis. The plague is primarily transmitted through flea bites or exposure to infected rodents. When someone is infected with the bacteria, it is highly contagious, and respiratory droplets are the primary mode of transmission. Antibiotics are the best treatment for the disease, but if left untreated, it can be deadly.

Tularemia is a bacteria that can be found in animals, particularly rodents, rabbits, and hares. The disease can be acquired through contact with the bacteria through the skin, ingestion of contaminated water or food, or inhalation of the bacteria. Symptoms of the disease can vary depending on how it is acquired but can include fever, chills, headache, muscle aches, and fatigue.

Failure of the foramen ovale to close after birth would result in mixed blood in the vena cava.

The correct option to the given question is option b.

The foramen ovale is a gap between the atria that allows blood to flow through the right atrium to the left atrium during fetal life. The majority of the blood will flow to the lungs to pick up oxygen during this time.However, when the baby is born, it must begin to breathe air and the pulmonary circuit must take over as the primary path for oxygenation.

As a result, the lungs inflate, the pulmonary pressure decreases, and the foramen ovale closes within a few hours of birth.Blood can go through the hole in the septum between the right and left atria, mixing oxygenated and non-oxygenated blood in the adult heart, if it fails to close.

The right ventricle then pumps this blended blood out of the heart and into the lungs. This can cause cyanosis in the infant, as well as congestive heart failure and a failure to thrive in severe cases.

Answer:

Coversion of substrate into products

Explanation:

A transform boundary is created when two plates pass one another. The right choice from the available alternatives is option C.

When two tectonic plates of the Earth pass one another, it forms a transform boundary. Localized faults or fissures may form as a result of the two plates interacting with one another as they pass one another. The following is a basic explanation of a transform border, but they are more complicated than that.

Two more boundary types aside from transform boundaries are divergent borders and convergent borders. At convergent boundaries, tectonic plates contact with one another; at divergent boundaries, they separate from one another. A transform boundary is created when two plates pass one another.

The people with lactose intolerance do not have enough lactase enzyme to digest lactose.What is lactose intolerance?Lactose intolerance is a situation that occurs when the body cannot digest lactose. Lactose is a sugar found in dairy products such as milk, yogurt, and cheese.

Lactose intolerance symptoms are bloating, flatulence, diarrhea, and abdominal cramps. It's important to note that lactose intolerance is not the same as a milk allergy. A milk allergy is an immune response, while lactose intolerance is a digestive issue. Lactase is an enzyme found in the small intestine's lining. Lactase breaks down lactose into glucose and galactose, which can be easily absorbed into the bloodstream.

However, if someone has lactose intolerance, it means that they do not have enough lactase enzyme to digest lactose. As a result, lactose remains in the digestive system, and bacteria in the colon ferment it, producing gas and causing the symptoms of lactose intolerance.

The question that a biological anthropologist might NOT address is: How have languages diversified over time?

Biological anthropology is a field of study that examines human biological variation, evolution, and the interaction between biology and culture. It encompasses a wide range of research topics related to human populations, genetics, evolution, and the relationship between humans and other primates.

While questions about genetic similarity among human populations, the influences on human evolution, and the relationship between humans and primates are all within the realm of biological anthropology, the diversification of languages over time falls more into the domain of linguistics and cultural anthropology. Language evolution and diversification involve complex social, cultural, and historical factors that extend beyond the biological aspects typically studied in biological anthropology.

Biological anthropologists focus on investigating genetic, anatomical, and behavioral aspects of humans and our primate relatives to understand our evolutionary history and the biological underpinnings of human variation. They examine genetic markers, fossil evidence, skeletal remains, and comparative anatomy to unravel our evolutionary past and explore the forces that shaped human populations and species over time.

While language and its evolution are undoubtedly important in the broader study of human culture and society, the specific investigation of language diversification is more commonly addressed by linguists, sociolinguists, and cultural anthropologists who study the social and cultural aspects of human communication and language development.

They have exposed ovules. Ovules are a feature that cycas share with angiosperms. Each plant is either all male or entirely female. The presence of ovules is what causes the similarity to angiosperms.

Gymnosperms like cycas have enclosed seeds with more intricate fertilisation systems, whereas cycas have unfertilized seeds that are open to the air to be directly fertilised by pollination.

Cycas often use a single species of very specialised pollinators. They are frequently identified by their thick, wooden trunk and crown of big, stiff, evergreen leaves. Usually, their leaves are pinnate.

Answer:

Lymphatic capillaries have thin walls, only as thin as a single cell. The cells overlap each other so that interstitial fluid easily enters the capillaries. Lymphatic capillaries are closed at one end. They contain a mini-valve that lets interstitial fluid flow into but not out of them.

Answer:

20%

Explanation:

cytosine = guanine = 30%

cytosine + guanine = 60 %

adenine + thymine =100% - 60% = 40 %

thymine = 20%

If a DNA molecule contains 30% cytosine, then 20% of the molecule should be thymine.

DNA stands for deoxyribonucleic acid. It is considered as the genetic material of most organisms. It is a complex molecule that bears genetic information.

Amount of cytosine = 30%

According to Chargaff's rule, A=T, C=G.

∴ Guanine = 30%

Now A + T = 40%

Therefore, the amount of thymine molecules is 20%.

Homologous recombination is most likely to occur during the S and G2 phases of the cell cycle, specifically during the late S and early G2 phases. This is because, during these phases, the sister chromatids are available as templates for repair.

Homologous recombination is a DNA repair mechanism that utilizes a homologous DNA sequence as a template to repair DNA damage, such as double-stranded breaks (DSBs). The process involves the exchange of genetic material between the damaged DNA strand and an undamaged homologous DNA strand.

During the S phase of the cell cycle, DNA replication occurs, resulting in the formation of two identical sister chromatids connected at the centromere. The newly replicated DNA strands serve as templates for homologous recombination repair. If a DSB occurs during the S phase, the sister chromatid can be used as a template for flawless repair.

As the cell progresses into the G2 phase, the replicated DNA is fully condensed and prepared for cell division. At this stage, the sister chromatids are still available and closely associated, making them suitable for homologous recombination repair.

Therefore, homologous recombination is most likely to occur during the S and G2 phases of the cell cycle when sister chromatids are present and available as templates for the flawless repair of double-stranded DNA breaks.
