water levels below what percent of a plants mass is usually fatal?
Water levels below 10-15% of a plant's mass are usually fatal.
This is because plants rely on water to carry out essential functions such as photosynthesis, nutrient uptake, and transportation. Without enough water, a plant's cells become dehydrated and unable to carry out these functions, leading to wilting, stunted growth, and eventually death.
Different plants have varying levels of tolerance to drought and can survive with lower water levels for longer periods of time, but in general, keeping a plant adequately watered is crucial for its survival and health.

Explain how the composition of blood changes as blood flows through the respiratory system Please identify TWO organs that interact and explain how the chemical composition of blood changes as a result. . 20 points!!!
Our total body weight accounts for about 7 to 8 % of blood. Blood is a mixture of around 55 percent plasma and 45 percent blood cells. Blood running through the veins, arteries and capillaries is called whole blood.
How does the blood change as it flows through the respiratory system?
Blood circulatory system, also called the cardiovascular system, delivers oxygen and nutrients to all the cells of the body.
The respiratory system consists of the respiratory passage and respiratory organ, that is the lungs.
Blood is carried to the lungs through the pulmonary arteries where it picks up oxygen. The blood then leaves the lungs and returns to the heart via the pulmonary vein. It then enters the left atrium. The blood then drops into the left ventricle through the mitral valve.
Transport of gases also occurs through blood.
For exchange or oxygenation, the deoxygenated blood is transported to the lungs from heart. Carbon dioxide is exchanged with oxygen as the blood flows through the respiratory system. For further circulation to various body parts, oxygenated blood is then transported to the heart.
Some amount of gases get dissolved in the blood plasma and get transported, whereas some amount of them is transported in the bound state.
So therefore, CO2 and oxygen bind with hemoglobin in RBC.

The lymphatic vessel that collects lymph from the left chest, abdomen, and lower limbs is called the thoracic duct.
The thoracic duct is the largest lymphatic vessel in the body and plays a crucial role in the lymphatic system. The thoracic duct begins in the abdomen, near the second lumbar vertebra, where it collects lymph from the intestinal lymphatic vessels called lacteals. It ascends through the thoracic cavity, alongside the aorta, and collects lymph from various organs and tissues along its course, including the left chest, left arm, left side of the head, neck, and upper thorax. Eventually, the thoracic duct drains into the left subclavian vein near the junction of the left internal jugular vein, returning the lymph back into the bloodstream. This junction is an important site where lymph from the thoracic duct combines with venous blood, allowing the transfer of immune cells and waste products from the lymphatic system to the circulatory system. The thoracic duct serves as a major pathway for the return of lymph and plays a crucial role in maintaining fluid balance, immune response, and nutrient absorption within the body.for more questions on thoracic

do members of the same phylum share more characteristics than members of the same class? Explain why or why not.
Answer: No, they don't.
Explanation:
In the taxonomic rank (Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species-- in that order) because phylum comes before class, it means it covers a broader spectrum of organisms. So, the traits are less specific. As you narrow it down, the members of the rank will share more and more traits in common.
Here is an example:
Humans are a member of the phylum chordata. All members of phylum chordata share the same 5 traits at some point in their lifetime. (Some only show the traits when they are embryos/larvae). These 5 characteristics share a tail, a notochord, a single, hollow nerve cord, pharyngeal slits, and an endostyle (thyroid).
So, now that we've established that humans are from phylum chordata, we can narrow it down to what class they are in. Humans are in the class mammalia, meaning they are mammals. All mammals not only share those 5 characteristics of phylum chordata, but they also share characteristics that unite them with each other. They all have hair, mammary glands in females, and are endothermic.
So, while members of the phylum chordata share at least 5 traits, members of the class mammalia share at least 8.

Deforestation occurs when large Amounts of trees are cut down and not replaced which of the following would result from deforestation
A. Decrease carbon in the atmosphere
B. Increased carbon in the atmosphere
Answer:
The correct answer is (B).
Explanation:
Deforestation occurs when large Amounts of trees are cut down and not replaced, which of the following would result from deforestation...
Increased carbon in the atmosphere
This statement is true because when trees become less abundant, the amount of oxygen being released into the atmosphere by trees via photosynthesis.
The circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.
What is Deforestation?Deforestation may be defined as the process of cutting down or eliminating trees in large numbers from our surroundings. This activity generally happens due to industrialization, wood extraction, urbanization, etc.
When the number of trees remains less in the environment due to deforestation or any other activity, the level of carbon dioxide in the atmosphere typically rises.
This is because carbon dioxide is considered the reactant of photosynthesis that is utilized by the plants along with water in the presence of sunlight and converted into oxygen.
But when the number of plants decreases, the level of carbon in the atmosphere increases, and the level of oxygen in the atmosphere decreases.
Therefore, the circumstance that would result from deforestation is the increased carbon in the atmosphere. Thus, the correct option is B.

Until fairly recently, average human life spans were less than 50 years. The major reason for this was that.
The major reason why the average human lifespans were less than 50 years until fairly recently is due to infectious diseases like tuberculosis, cholera and smallpox. It was also because the causes and cure of other major diseases like malaria and plague had not yet been found.
The lifespan of an entire population of people is known as the life expectancy, while the lifespan of an individual is a measure of the length of a person's life. Until recent years, causes, modes of transmission and treatment of common diseases were not known. Access to good medical care was difficult and hygienic conditions then were very poor. For example, it wasn't until the mid-1800's that people came to know that washing of hands could stop the spread of diseases, and until the late 1800's doctors didn't adequately wash their hands before performing a surgery.
Unhygienic conditions also made it easier for deadly infectious diseases like the Bubonic plague, the Black plague and the Spanish flu to spread, further reducing the already low life expectancy.
Today, thanks to good hygiene, better understanding of transmission of microbes, environmental sanitations, early immunizations and access to clean water, life expectancy has increased.

Dispersion is the change in the distribution area of populations. Snail: Daily Movements. Seeds: Passive dispersal. Fishes: One return journey. Butterfly: One way only.
What is dispersion?Dispersion is the change of range or distribution area. It refers to the movement of individuals or populations from one place to another one.
Dispersion is the dissemination and distance of some individuals from others. Each individual is considered the dispersion unit, being able to have different mobile stages.
Dispersion ends by causing changes in the distribution area.
Dispersion events might be
Ecological processes → to avoid intraspecific competition for resources. It might involve daily or seasonal migration. Intra-area movements. Biogeographical processes → Involve the individual movement in a wider area. Extra-area movements.There are different types of dispersion,
Jump dispersion → one or a few individuals of the same generation are capable of evading a barrier and getting to a new area where they establish themselves. This is the case of dispersion to an island.Diffusion → A whole population, through many generations, can reach wider areas by exploring and expanding to new favorable regions.
Secular migration → Diffusion events in too many generations. Involves evolution and speciation.

What is the nervous system?
The nervous system is a complex system of cells, tissues, and organs that are involved in the regulation and coordination of the body's functions.
The nervous system is divided into two major parts: the central nervous system (CNS) and the peripheral nervous system (PNS).
The CNS is made up of the brain and spinal cord, while the PNS is made up of nerves that connect the CNS to the rest of the body.
What is the fight-or-flight response?
The fight-or-flight response is a natural response of the body to stress.
It is a survival mechanism that helps an organism respond quickly to a perceived threat.
When the body senses a threat, the sympathetic nervous system is activated, which leads to the release of adrenaline and other stress hormones into the bloodstream.
This causes several changes in the body, including an increase in heart rate and blood pressure, faster breathing, and a surge of energy.
How does the sympathetic nervous system activate the fight-or-flight response?
