A student conducted an experiment to test whether talking to plants would help them to grow faster. he set up the following two groups: group 1: spoken to and hand watered group 2: not spoken to and watered with sprinklers after three weeks, the plants in group 1 showed much more growth than those in group 2. based on the results of this experiment, which is the best conclusion? they are valid because the student ran a controlled experiment. they are not valid because the student did not control all the variables that can affect plant growth. they are valid because the dependent variable caused a change in the independent variable. they are not valid because the time frame to grow a plant is too short.

Answer:

C

Explanation:

i did this in my science

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.

These plants produce most of these chemicals as they need to adapt to survive in osty environments.

The transformation of a plant into a medicine aims to preserve the chemical and pharmacological integrity of the plant drug in order to guarantee the constancy of its biological and/or pharmacological action and the safety of its use, in addition to valuing its therapeutic potential.

With this information, we can conclude that these plants produce most of these chemicals as they need to adapt to survive in osty environments.

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.

The statements on how organisms in a food chain store food that is Not true are :

Organisms in the food chain contribute greatly to the flow of carbon in the atmosphere by consuming, storing and expelling carbon in variuos form to help regulate the flow of carbon in the carbon cycle. Algae use carbon dioxide during photosynthesis to produce glucose which is stored for use. also as the crab ingests snails and other marine organisms it stores the carbon for use as a source of energy.

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.

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

The urine-collecting structures found within the kidney are:

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.
