As cold, briny water from the antarctic circulates to the equator, it warms and rises. as it does, this upwelling carries nutrients that produce ____ billion tons of phytoplankton that are eaten by fish and birds. those that are not eaten die, and fall back to the ocean floor, carrying nutrients with them.
Brackish water is water that has extra salt than original water. This may appear from the crossing of seawater by fresh water that may occur in brackish specimen aquifers. The nutrients that produce 45 billion ton phytoplankton. The phytoplankton is bacteria that is a significant autotrophic element of the plankton community and a fundamental component of water that basin ecosystems. Though it is an essential source of food for larger animals as being the first form of food chain.
Julia plants three tomato plants in different types of soil to see which is best for gardening. All three tomato plants are the same variety. They are about the same size at the start of the experiment. Each plant receives the same amount of water each day. The independent variable is the
The independent variable in Julia's experiment is the type of soil. By planting three tomato plants in different types of soil and keeping all other factors the same, Julia can observe and compare the growth of the plants to determine which type of soil is best for gardening.
Explanation:The independent variable in Julia's experiment is the type of soil. In her experiment, Julia is testing how different types of soil affect the growth of tomato plants. The independent variable is the factor that is intentionally changed by the experimenter, which in this case is the different types of soil. By planting three tomato plants in different types of soil and keeping all other factors the same, Julia can observe and compare the growth of the plants to determine which type of soil is best for gardening.
Final answer:
The independent variable in Julia's experiment is the type of soil, which is varied to observe its effect on the growth of tomato plants, with other factors like water and plant size being consistent.
Explanation:
In the context of the experiment described, the independent variable is the type of soil used for growing the tomato plants. An independent variable is the one that is changed or controlled in a scientific experiment to test the effects on the dependent variable. In Julia's case, she is using different types of soil to determine which one leads to the best growth for tomato plants, while keeping other factors such as the amount of water, the size and variety of the plants consistent. Gary's experimental setup also highlights the importance of controlling variables to ensure that the results reflect the effects of the independent variable, which in his experiment is the amount of sunshine. By maintaining consistent conditions such as the amount of water and plant food, as well as the size and type of pot, he aims to ensure that the differences in plant growth can be attributed to the sunlight exposure.

The presence of the protein albumin in the urine is known as
Final answer:
Albumin in the urine, referred to as proteinuria or albuminuria, is a sign of kidney damage indicating that glomeruli are not properly filtering proteins out of the blood.
Explanation:
The presence of the protein albumin in the urine is an indication that the filtering units of the kidneys, known as glomeruli, are damaged, and this condition is referred to as proteinuria or, more specifically, albuminuria. Protein molecules, including albumin, are usually retained within the glomerular capillaries due to their size, but when the kidneys are damaged, albumin can pass into the urine. This may occur in various health conditions such as diabetic nephropathy, hypertension, or kidney diseases. It is essential to detect and manage albuminuria early to prevent further kidney damage.

Identify two ways in which animals can reduce the intensity of intraspecific competition
Final answer:
Animals can reduce intraspecific competition by changing behaviors to minimize competition and by niche differentiation, where they use different resources or habitats within the same environment.
Explanation:
Two ways in which animals can reduce the intensity of intraspecific competition include behavior changes and niche differentiation. Firstly, animals can change their behaviors to avoid direct competition for resources, such as switching their active hours to avoid competition for food. Secondly, they can engage in niche differentiation where individuals of the same species exploit different habitats or resources, reducing direct competition. An example of this in interspecific competition is observed in anolis lizards, where specialization in their habitat selection, such as being ground-dwellers or tree-dwellers, decreases the overlap in resource use among different species. Similarly, in intraspecific competition, animals of the same species can evolve different adaptations that allow them to use varied resources or live in different habitats, thus reducing direct competition for the same resources.

Explanation:
Breast milk _____. is more likely than formula to produce allergies is deficient in iron and vitamin c provides antibodies to fight diseases upsets the baby's digestive system more than formula
Breast milk provides antibodies to fight diseases.
Breast milk is produced by mammary glands in the breasts and its main function is feeding an infant. Breast milk is the primary source of nutrition for newborns. The composition of the milk includes immune-boosting white blood cells, as well as stem cells, which can help organs develop, antibodies, proteins, amino-acids, oligosaccharides, growth factors, hormones, enzymes, vitamins, minerals…
Final answer:
Breast milk provides antibodies to fight diseases, which are crucial for the infant's developing immune system
Explanation:
Breast milk provides antibodies to fight diseases, which are crucial for the infant's developing immune system. These antibodies are passed to the infant through breast milk in what is known as active immunity. The immunoglobulins in colostrum and breast milk help increase the newborn's immune defenses. Breast milk contains all the necessary nutrients and hydration that a growing infant requires for the first 4–6 months of life and is tailored to suit each stage of the newborn's development.
The composition of breast milk helps the newborn's digestive system to expel meconium and clear bilirubin and is generally less likely to upset the baby's digestive system than formula. Compared to cow's milk, breast milk has more appropriate levels of fat and lactose for an infant's needs and contains proteins that are easier for the infant to digest. Cow's milk contains more protein and minerals, which are difficult for an infant's immature digestive system to metabolize, and therefore, it should not be given to infants.

Gil's mother calls to make an appointment for her son. she reports that he has had an elevated temperature for 24 hours, ranging from 99° to 102.8° f. mrs. harris is describing which type of fever?
Final answer:
Gil's fever with temperatures fluctuating between 99° and 102.8° F suggests an intermittent fever, likely caused by a viral or bacterial infection, and while fevers can be beneficial in fighting infection, high fevers may require medical attention.
Explanation:
The fever described by Mrs. Harris for her son Gil, with a temperature range from 99° to 102.8° F (37.2° to 39.3° C), is likely intermittent. This type of fever is characterized by elevated temperatures that vary throughout the day but return to normal or subnormal levels at least once in 24 hours. The possible cause of Gil's fever could be a viral or bacterial infection, as fevers result from the body's immune response to these pathogens, leading to an upward adjustment of the body's temperature set point. It is also important to recognize that fever can play a beneficial role in fighting infections by inhibiting the growth of pathogens and speeding up cellular repair processes. However, if a fever becomes dangerously high, medical intervention may be necessary to prevent complications.
