What is the order of urine-collecting structures found within the kidney?.
The urine-collecting structures found within the kidney are:
Renal pyramidsMinor calyxMajor calyxRenal pelvisUreterWhat are Urine-collecting structures?The urinary system includes the systems that collect and carry urine from the kidneys to the bladder for removal from the body. Renal pyramid, minor and major calyces, renal pelvis and ureter are some of these structures.
1. The renal medulla contains triangular-shaped structures called renal pyramids, which are filled with urine-collecting tubules.
2. Minor calyx: These are small, cup-shaped organs that collect urine from the collecting ducts of the pyramids of the kidneys.
3. Major calyx: These are large, cup-like structures that form when several smaller calyces come together. They receive urine from the corpus luteum as they empty into the renal pelvis.
4. The ureter, which carries urine to the bladder, receives urine from the main calyces, a funnel-shaped structure in the renal pelvis.
5. A muscular tube known as the ureter carries urine from the renal pelvis to the bladder.

How does most carbon enter living things?
Answer:
Through the process of photosynthesis, carbon dioxide is pulled from the air to produce food made from carbon for plant growth. Carbon moves from plants to animals. Through food chains, the carbon that is in plants moves to the animals that eat them. Animals that eat other animals get the carbon from their food too.

What is a red drums diet.
Answer:
Red drums prey upon smaller fish such as anchovies and menhaden, as well as crabs and shrimp. Juveniles eat zooplankton and small invertebrates.
Explanation:
Feeding habits, seasonal diet variation, and predator size-prey size relationships of red drum (Sciaenops ocellatus) were investigated in Galveston Bay, Texas through stomach contents analysis. A total of 598 red drums ranging from 291–763 mm in total length were collected and their stomach contents were analyzed during fall 1997 and spring 1998. The diet of red drum showed significant seasonal patterns and was dominated by white shrimp (Penaeus setiferus) during fall and gulf menhaden (Brevoortia Patronus) during spring. Blue crab (Callinectes sapidus) was an important component of red drum diets during both seasons. Significant differences existed between prey types consumed during fall and spring as the red drum diet reflected seasonal variation in prey availability. Predictive regression equations were generated to estimate the original carapace width of blue crabs from several measurements taken from carapace fragments recovered in red drum stomachs. Regressions were highly significant (r2>0.97) and increased the number of blue crabs with size information nearly threefold. Predator size-prey size relationships were determined for red drum feeding on white shrimp, gulf menhaden, and blue crab. Although regression slopes were statistically significant, prey sizes increased only slightly with increasing red drum size. Comparisons of prey sizes consumed by red drums with sizes occurring in the field indicate that red drums feed in nearshore shallow-water habitats, which serve as nursery areas for many juvenile fishes and crustaceans. Our findings demonstrate that red drums feed on several prey species of commercial and recreational value and may have important effects on estuarine community structure.

A student has twenty identical young plants how does the amount of water given to these plants each day effect how tall the plant will grow
Answer:
The amount of water given to the plants depends on the effect of how tall the plant can overall grow. For instance, if all twenty identical plants are being given the same amount of water, then they will grow all at equal rates. However, if there is not equal amount/consistency with the amount of water the plants receive, then this factor may contribute to an uneven growth pattern between all twenty plants. However, other factors (such as location, sunlight, etc.) may also contribute to a plant's growth.
As the global population of humans increase, the number of deaths by natural disasters is expected to _______.
Answer:
increase
Explanation:
Population growth and distribution, especially increased population density and urbanization, increases vulnerability to disasters
As the global population of humans increases, the number of deaths caused by natural disasters is expected to increase. The reason for this is that the more people there are, the more natural resources they will consume. This resulted in the natural disaster.
What is the effect of the population rise?The increase in population will have a negative impact on nature. The greater the population, the greater the demand for resources for living, feeding, transportation, and so on. Urbanization will increase as a result of their desires, resulting in more deforestation.
As the plant's rate of photosynthesis and rainfall decrease, so does its oxygen level. All of these have a negative impact on various ecosystems, plants, and animals. The melting of polar ice causes a rise in water level as a result of global warming. This leads to flooding, cyclones, and other natural

what kind of electrical charge is found on a hydrogen atom of a polar water molecule
Answer:
A negative charge exists because of the electronegativity of oxygen. A polar water molecule is made up of hydrogen and oxygen. Due to its atomic structure, there is an unequal distribution of charges and thus oxygen gets a more negative charge while hydrogen gets a positive charge.
