Land that used to be a meadow is converted to a housing development. the next year, fewer milkweed flowers are observed. what happened?
A former meadow is turned into a housing complex, and the next year, fewer milkweed blooms are seen due to pollination.
What applications does milkweed have?
The herb has also been used medicinally despite the danger of poisoning. Many native cultures chewed the roots of milkweed to heal diarrhea and used the sap to remove warts. Infusions and salves were also made from it to treat asthma, coughing, fevers, rashes, and swelling.
What kind of soil is ideal for milkweed growth?
In regions with more rainfall, like the eastern United States, milkweed thrives. Asclepias tuberosa, sometimes known as butterfly weed, thrives in drier climates like those in the western United States. Sand or gravelly soils are required.

In response to a specific stimulus, autonomic reflex arcs can trigger which responses?
In response to a specific stimulus, autonomic reflex arcs can trigger smooth muscle contraction, cardiac muscle contraction and secretion by glands.
An element of the peripheral nervous system that controls unconscious physiological functions is the autonomic nervous system. The reflex arc is a unique kind of neural circuit that starts with a sense neuron at a receptor (for instance, a pain receptor in the fingertip) and ends with a motor neuron at an effector (e.g., a skeletal muscle).
Heart rate, digestion, respiration, salivation, sweat, pupillary dilation, micturition (urination), and sexual desire are all influenced by the ANS. Because sympathetic and parasympathetic activation are recruited quickly and synchronously, autonomic reflex arcs are complicated in character.

Water drains into the sinkhole pollution due to factories
The lake was created as limestone gradually dissolved, causing the sediment layer above it to collapse and creating the lake basin. Low lake levels and slow draining can be caused by bottom leaks, sinkholes, and swallets, long-term dryness, and a lack of recent, strong rainfall events.
What causes lake Jackson to disappear ?Before the lake dried up, those walking along the shore of the sinkhole at Lake Jackson on Thursday would have been in three to four feet of water.
Environmentalists refer to the process as a "dry down," and it occurs every ten or twenty years.

What mechanism of evolution would tend to favor adaptations that reduce competition between species living in the same place?.
Natural selection mechanism of evolution would tend to favor adaptations that reduce competition between species living in the same place.
According to the theory of natural selection, features that may be passed down enable animals to adapt to their environment more effectively than other members of their own species. As a result, the species evolves because it can survive and reproduce better than other members of the species. One of the mechanisms or causes of evolution is natural selection. Physical or behavioral characteristics that help an organism fit in with its surroundings are called adaptations. Random mutations result in heritable variation.Natural selection may result in speciation, the process by which one species gives rise to another that is utterly separate.

An increase of _____ increases the permeability of the collecting duct to water.
An increase in Antidiuretic hormone increases the permeability of the collecting duct to water.
The brain releases a substance called antidiuretic hormone (ADH), which makes the kidneys release less water and reduces the volume of urine generated. The body makes less pee when its antidiuretic hormone level is high. A low level causes more urine to be produced. Water is retained, blood volume rises, and symptoms such as nausea, headaches, confusion, lethargy, and low blood sodium may occur if there is too much antidiuretic hormone.
The kidneys will secrete too much water because of low anti-diuretic hormone levels. Dehydration and a drop in blood pressure will result from an increase in urine output. antidiuretic hormone is a chemical that is created in the hypothalamus, a region of the brain. The pituitary gland, located near the base of the brain, then releases it.

Explanation:
The enzyme produced in the kidneys that may play a role in essential hypertension by promoting vasoconstriction is called renin.
Renin is an enzyme released by specialized cells in the kidneys called juxtaglomerular cells. It plays a critical role in regulating blood pressure and fluid balance.
It acts on a protein called angiotensinogen, which is produced by the liver and released into the bloodstream. Renin cleaves angiotensinogen to produce angiotensin I.

What explains why the abdomen of the drop keeping mosquito is cooler than the head
A Final statement or concluding statement
The mosquito uses evaporative cooling to stay cool. A noticeable temperature gradient can be seen along the mosquito's body as a result of the abdomen's temperature falling due to the retention of the fluid drop attached to it. They are able to avoid the harmful physiological effects of thermal stress thanks to this drop in temperature.
How does weather affect mosquito?Mosquitoes go dormant at 50 degrees or lower. However, the mosquitoes are not actually killed by the cold winter temperatures. Mosquitoes have established modifications that enable them to hibernate during cold conditions, as long as the temperature is within a typical range for your region. Some species, which would perish in the cold, have reproductive techniques that allow the eggs to live and hatch the next season when the weather warms up. Even in Alaska, mosquito problems exist.

Explain how hormones, nervous system stimulation, and the volume, chemical composition, and osmolarity of the chyme affect motility in both the stomach and the duodenum.
Hormones control the different digestive enzymes that are secreted in the stomach and the intestine during the process of digestion and absorption.
Hormones, nervous system stimulation:
The medulla and the vagus nerve both play a role in receptive relaxation, which is when the smooth muscles of the stomach's body and fundus relax to allow the stomach to fill. The strength of the peristaltic waves that stir the chyme is controlled by the vagus nerve and the release of a few hormones (serotonin in the stomach and intestinal gastrin in the duodenum).
Due to a negative feedback loop that slows gastric emptying, motility is slowed when the sensory receptors in the wall of the duodenum detect a high degree of stretch, a low pH, a high lipid content, or a high solute concentration in the chyme. The vagus nerve and the duodenum-secreted hormones secretin, cholecystokinin, and gastric inhibitory peptide mediate this loop.
