What do isotherms show? Points of equal humidity Points of equal wind speed Points of equal air pressure Points of equal temperature
Answer:
points of equal temperature
Explanation:
The isotherms are closed circular lines that connect dots where the temperature has same value. These lines are very easy to read and they are very useful when it comes to reading a map that has them on, as they will provide us with the information about the temperature. The isotherms are often used in the weather programs and meteorological prognosis, so we pretty much see them every day, but unfortunately the majority of the people do not know what they are and what are they representing.
Simple Answer:
D-- points of equal temperature

Sickle-cell anemia is an example of codominance.What implications does this have for people with one or two copies of the sickle-cell gene?
a) people with two copies of the mutated gene have healthy red blood cells.people with one copy of the mutated gene dont have the disease but are carries of the disease.
b) people with two copies of the mutated gene have sicke cell anemia. people with one copy of the mutated gene have healthy red blood cells.
c) people with two copies of the mutated gene have sickle cell anemia. people with one copy of the mutated gene have both healthy and misshapen red blood cells and are carriers of the disease
d) people with two copies of the mutated gene are carriers of the disease. people with one copy of the mutated gene dont have the disease
please help!
Answer:
C
Explanation:
Codominant alleles mean that both alleles are expressed in the trait of the organism because no one alleles mask the effects of the other. Therefore an individual heterozygous for sickle cell will have both healthy and sickle cells in his blood. This is similar to plants with codominant alleles for petal color. If red and white color alleles are codominant, then the petals will have red and white patterns on the petals.
people with two copies of the mutated gene have sickle cell anemia. people with one copy of the mutated gene have both healthy and misshapen red blood cells and are carriers of the disease.
Optio nC is correct.
How do we explain?Sickle cell anemia is a genetic disorder that is caused by a mutation in the hemoglobin gene. Hemoglobin is a protein that carries oxygen in the blood. The mutation in the sickle cell gene causes the hemoglobin molecules to form into long, rod-like shapes. These rod-like shapes can clog up the blood vessels, which can lead to a variety of health problems, including anemia, pain, and organ damage.
People with two copies of the sickle cell gene have sickle cell anemia. They have all of their red blood cells shaped like rods, which can cause severe health problems.

Which statements describe primary consumers? Check all that apply.
A food chain is the sequence of who eats whom in a biological community (an ecosystem) to obtain nutrition. A food chain starts with the primary energy source, usually the sun or boiling-hot deep sea vents. The next link in the chain is an organism that make its own food from the primary energy source -- an example is photosynthetic plants that make their own food from sunlight (using a process called photosynthesis) and chemosynthetic bacteria that make their food energy from chemicals in hydrothermal vents. These are called autotrophs or primary producers.
Next come organisms that eat the autotrophs; these organisms are called herbivores or primary consumers -- an example is a rabbit that eats grass
A primary consumer is an organism that feeds on primary producers. Organisms of this type make up the second trophic level and are consumed or predated by secondary consumers, tertiary consumers or apex predators.

A feedback mechanism that serves to decrease the stimulus and bring a system back to
homeostasis is called a
A. negative feedback mechanism
or
B. positive feedback mechanism
Answer:
A. negative feedback mechanism
Explanation:
A negative feedback implies stimulation towards less change and restoration of the normal state.
A mechanism that serves to decrease the stimulus and bring a system back to homeostasis therefore shall be referred to as a negative feedback mechanism.
This is because homeostasis is the normal state, mechanisms bringing further change to homeostasis can be referred to as positive feedback mechanism and vise versa.
A feedback mechanism that decreases the stimulus and brings a system back to homeostasis is known as a negative feedback mechanism.
Explanation:A feedback mechanism that serves to decrease the stimulus and bring a system back to homeostasis is called a negative feedback mechanism. This process helps to maintain stability in our body by reversing any deviations from the normal levels. Negative feedback does this by triggering responses that counteract changes, bringing the variable back to a set point. For instance, the maintenance of blood glucose levels is a classic example of a negative feedback mechanism. After eating, blood glucose levels rise, which are detected by the pancreas that releases insulin, thereby lowering the glucose levels back to normal.
Conversely, negative feedback also works if glucose levels are too low; the pancreas releases glucagon to increase the glucose levels. The primary function of negative feedback loops is to prevent physiological variables from going beyond the normal range, essentially turning systems 'off' or 'on' to achieve stability. Hence, negative feedback mechanisms are the predominant system used to sustain homeostasis.
HELP!!!! Which of the following correctly relates the porosity, permeability and production of a well in an aquifer?
a. Increasing porosity and decreasing permeability lead to increased production in an aquifer.
b. Decreasing porosity and increasing permeability lead to increased production in an aquifer.
c. Decreasing porosity and decreasing permeability lead to increased production in an aquifer.
d. Increasing porosity and increasing permeability lead to increased production in an aquifer.
D-Increasing porosity and increasing permeability lead to increased production in an aquifer
Answer:
d. Increasing porosity and increasing permeability lead to increased production in an aquifer.
Explanation:
Underground aquifers are permeable geological formations that allow water to accumulate inside the soil. Depending on how water circulates within the soil, there are three primary types of aquifers: porous, karstic and fissural.
In addition to supplying sufficient water to keep surface watercourses stable (production function), aquifers also help prevent their overflow by absorbing excess heavy rainwater (regularization function).

How does the hydroelectric dam picture here impact the environment?
By releasing toxic chemicals in their emissions
By generating Significant heat that artificially warms nearby water
By producing greenhouse gases
By blocking fish migration
Answer:
By blocking fish migration
Explanation:
By releasing toxic chemicals in their emissions
Hydroelectrics only emissions are usually, non harmful electromagnetic signals.
By generating Significant heat that artificially warms nearby water
Possible, but they do not produce much significant heat
By producing greenhouse gases
No, just no- its magnets that are water moved, no room for greenhouse gasses..
By blocking fish migration
It is a dam, blocking a river, with fish in it.
By blocking fish migration the hydroelectric dam will impact the environment.
Because the emissions they produce include hazardous substances. The only pollutants that hydroelectric power typically produces are electromagnetic pulses that are harmless. By producing a significant amount of heat, which artificially heats the water in the surrounding area.
Although they do not generate a considerable amount of heat, they are a possibility. Because of the emission of greenhouse gases. No way, absolutely not; the water is propelled by magnets, and there is no place for greenhouse gases. By impeding the movement of fish. There are fish in the river that is being blocked off by the dam.

Answer:
photosynthesis and lipids
Explanation:
Answer:
The correct answer is - structural support and storage for energy.
Explanation:
The bamboo is like most of the other plants produce carbohydrates by the process of photosynthesis. Plants convert glucose by polymerization into starch and polysaccharide for storage as an energy source and cellulose for cell wall structure and support.
Starch and polysaccharides provide energy by digesting the covalent bonds through the cellular respiration process. cellulose form the cell wall of the plant cells and gives it strength and support.
Thus, the correct answer is - structural support and storage for energy.

Which of the following is a correctly balanced equation?
B. is the answer because the number of moles of the reactants is equal to the number of moles of the products
Answer : The correct balanced equation is,
[tex]2HgO\rightarrow 2Hg+O_2[/tex]
Explanation :
Balanced chemical equation : It is defined as the number of atoms of individual elements present on reactant side must be equal to the product side.
The balanced chemical reaction is,
[tex]2HgO\rightarrow 2Hg+O_2[/tex]
This chemical reaction is balanced reaction because in this reaction, the number of atoms are balanced on both the sides.
While the other equations are not balanced because the number of atoms are not balanced on both the sides.
Hence, the correct balanced equation is,

Seasons are caused by ____. (1 point)
a).Earth’s rotation
b.) precession
c.)Earth’s tilted axis
d.)Earth’s distance from the sun
Answer:
Earth's tilted axis
Explanation:
The axial tilt of the Earth causes either the northern or southern hemisphere to be closer to the sun, causing seasons
a).Earth’s rotation
This causes the day night cycle, not seasons.
b.) precession
Precession is the movement of the earth's axis in its orientation with its orbit, for example the orbit changing from lets say 15 to 20 degrees.
d.)Earth’s distance from the sun-
If this were true, all the earth would have the same seasons, but they do not.
Seasons are primarily caused by Earth's tilted axis. This tilt, combined with Earth's orbit around the Sun, results in different parts of Earth receiving different amounts of sunlight at different times of the year, creating the seasons.
Explanation:The seasons are primarily caused by Earth’s tilted axis, which is angled at about 23.5 degrees relative to its orbital plane. As the Earth orbits the Sun, this tilt causes different parts of the Earth to receive varying amounts of sunlight at different times of the year. In the summer months, the hemisphere tilted towards the Sun experiences longer, sunnier days, (i.e., summer), while the hemisphere tilted away experiences winter. Conversely, during winter, the hemisphere tilted away from the Sun experiences shorter, darker days. Earth’s rotation and precession do affect the Earth’s climate but are not the primary causes of the changing seasons. Similarly, Earth’s distance from the Sun varies slightly due to its elliptical orbit but doesn’t significantly affect the seasons.
