Answer:
Options include building dams to trap water from rivers, pumping water from the ground, and dredging for new sources of water. Each of these activities can change the timing and amount of freshwater that enters our estuaries, and natural drought cycles only make their effects worse

Which of the following is NOT a response that the body would have to a stimuli?
A. physical response
B. chemical response
C. creating a feeling
D. evolving the body
Answer:
Explanation:D
The CNS, which is made up of the brain and spinal column, coordinates how the body reacts to stimuli.Motor neurones are used by the CNS to communicate with an effector.A hormone or a muscle in the body that causes a response is known as an effector.
How does your body respond to stimuli?
The creating feeling is not involve stimuli .Anything that makes you react, like the smell of food making your mouth moisten, is a stimulus.Body movements such as muscle contractions, gland secretions, or brain operations are responses. The stimulus is a change in the environment, and the response is how the organism responds to it.In single-celled organisms, the reaction is a result of a cell characteristic...An organism's senses, which are delicate components of his body, respond to stimuli. The sensory input from the outside world consists of touch, pain, vision, smell, taste, sound, and balance (equilibrium).External changes trigger the activation of these sensory impulses.Touch and pain: The stimulus that can have a significant impact on the body is pain.The definition of a response is a response to an activity.The way a person responds to an ink stain on a card is an illustration of response.An answer to a question is what is meant by a response.What follows a question in a question-and-answer session is an illustration of a response. Animals react to a stimuli in order to maintain their current circumstances.Examples of this include leaving a place that is too chilly and moving somewhere warmer.if hungry, moving in the direction of food. The body's automatic responses to a stimulus are known as physiological responses.The natural and instinctual physiological reactions we encounter every day are familiar to most of us, but we frequently ignore them. The various tastes of the various foods you eat are an example of chemical stimulation.When chemical messengers (hormones) interact with cells, biological stimuli are observed. To preserve homeostasis, your body also needs to keep secure and defend itself.In order to preserve homeostasis, the body reacts to stimuli.The body quickly resumes its normal state as a result of these intricate responses.We would get frequent fevers and other illnesses if they didn't.To learn more about stimuli refer

1. Compare the density of stomata between the two varieties of olive plant A and B
2. Under identical environmental conditions the rate of water uptake in plant A is higher than plant B
Plant A has more stomata than plant B and therefore plant A can take more water, thereby under identical environmental conditions, the rate of water uptake in plant A is higher than in plant B (questions 1 and 2).
What are plant stomata?Plant stomata are structures located on the leaves which serve to absorb water and they also serve to the gas exchange processes during photosynthesis, which is fundamental because one output of this process is oxygen while the input is carbon dioxide.
The amount of plant stomata per unit of area is fundamental to determining the water intake rate that a plant has in certain environmental conditions.
Therefore, with this data, we can see that plant stomata are required to take water and also for gas exchange during photosynthesis, thereby a plant with more stomata will be able to obtain more water.

what happens to jay’s motion at 30 minutes into his run
Answer:
Jay's speed-7.333 yd/s
Zeke's speed- 7.0 yd/s
Zeke's time-31.43 seconds
Step-by-step explanation:
-Speed is defined mathematically as distance over time.
-Given the distance as 220 yds and Jay's time as 30sec, her speed is:
#Given that Jay wins the race by 10yds, it means that Zeke was at 210 yds when Jay finished:
-Find Jay's time at d=210 yds:
#Zeke's speed for the race can now be calculated as:
#Time it takes for Zeke to finish:
Hence, it takes Zeke 31.43 seconds to complete the dash.

what is reproduction and explain the types of reproduction in plants?
Answer:
The production of new individuals from their parents is known as reproduction.
The types of reproduction in plants are:-
asexual : There are several methods of asexual reproduction such as fragmentation, budding, spore formation and vegetative propagation.
Sexual: Sexual reproduction involves the fusion of male and female gametes.

4. Do you think 20 ml of soda has a greater mass than 20 ml of water? Design an experiment to test this. Explain how you will
determine which one (soda or water) has the most mass.
Yes, in my opinion 20 ml of soda has a greater mass than 20 ml of water due to higher weight of soda particles as compared to water.
It is because solid substance is more denser than liquid. In 20 ml of soda, there are solid particles in it which make it heavier and denser than liquid water. In order to design this, we have to take two solutions, one having soda whereas the other has water in liquid form with equal concentrations. Then we have o find the density of both solution, that solution which has more density is considered as heavier than other solution. The density of soda is 2.54 g/cm³ whereas the density of water is 1 g/cm³ so it is clear that soda is denser than water.

1-Water is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. 3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.

Which would be considered a reliable source?(1 point)
an opinion column in your favorite magazine
an article from a scientific journal
a blog written by an anonymous author
a biology textbook from 1920
When looking for updated and reliable information, you always need to point to scientific journals, magazines, encyclopedias, or textbooks recently printed or published. In the exposed example, the most reliable source is an article from a scientific journal.
----------------------------------------
When looking for updated and reliable information, you need to be careful with the source, authors, and publishment dates.
In general, scientific journals, magazines, encyclopedias, or textbooks are sources of reliable information. The material exposed on these sources has been previously checked and evaluated by a group of people trained and capable to do so. If your favorite magazine is not a scientific one, you should look for another source.
You also want to consider the authors. Some researchers are very well known, and their publications probably reflect years of investigation. By looking for these authors´ publications you will ensure a good source. You should use a blog written by a well-known author, but not a blog that is written by an anonymous one.
You also need to consider that your source should be recently printed or published. Science is very dynamic and continuously changes. Discoveries always replace old information. So when looking for a reliable source, you need to look for recent publications. A biology textbook from 1990, although it is a reliable source, it probably has old information.
