A. deciduous trees
B. grasses
C. small shrubs
D. cone-bearing trees
Answer:
Small Shrubs
Explanation:
They Give off energy that makes them dominate the coniferous forest biome
The dominant plant life in the coniferous forest biome are cone-bearing trees, also known as conifers.
What is a coniferous forest biome?Coniferous forests are found in areas with cool, moist climates, such as the taiga regions of North America, Europe, and Asia. These forests are characterized by their dense stands of evergreen trees that are adapted to the long, cold winters and short growing seasons of their native habitats. The most common types of conifers in these forests include species of pine, spruce, and fir.
Conifers are easily recognizable by their distinctive needle-like leaves and reproductive structures, which are cones that contain the seeds. These adaptations allow conifers to conserve water, resist cold temperatures, and reproduce efficiently, making them well suited to the harsh conditions of the coniferous forest biome.
In contrast, deciduous trees, grasses, and small shrubs are more commonly found in other biomes, such as deciduous forests and grasslands.

Priscilla was building a circuit that used copper wires to connect a battery to a light bulb. As she connected the final wire from the light bulb back to the battery, the light bulb turned on. Priscilla knew that current was now flowing through her closed circuit. What makes the current in the circuit flow?
Answer:
The complete path provided by the closed circuit enables electric current produced by the battery to flow round the circuit
Explanation:
Electric current consists of charges (electrons) in motion from one region to another.
An electrical circuit is any closed path through which electric current can flow.
An electrical circuit consists of an energy source that supplies the electrons moving, a path along which the electrons can travel, and a load or appliance that uses the electrical energy. When the circuit is broken at any point, electrons will cease to flow since there is no complete path for it to flow. Such a circuit is known as an open circuit.
In the circuit built by Priscilla, the battery serves as a source of energy by providing the electrons that moves round the circuit. The wires provides the path for electrons to flow from the battery through the light bulb and back to the battery. When she connected the final wire from the bulb back to the battery, the circuit becomes complete/closed and current then flows to light up the bulb.

1. When a consumer eats a producer, 10 percent of the producer's energy is passed on to the consumer trophic level. What happens to the other 90 percent?
A. It is added back to the soil by decomposers.
B. It is used by the producer to pass on to the next trophic level.
C. It is used for cell processes or released as heat.
D. It is consumed and used by the consumer.
2. Why is there less biomass at the top of the energy pyramid?
A. Secondary and tertiary consumers have to consume a lot more food to support themselves, so there are fewer of them.
B. Secondary and tertiary consumers live longer, so there are fewer of them because they reproduce more slowly.
C. Secondary and tertiary consumers are larger, so there are fewer of them.
D. Secondary and tertiary consumers have bigger ranges, so there are fewer of them because they each need a lot of space.
3. Using the ten percent rule, determine how many kilocalories of energy the tertiary consumer tuna will receive.

Consumers are the organisms that depend on others for food and energy for the metabolic process while the producers produce their food at the trophic levels.
The correct options are 1. C, 2. A, 3. A, 4. A and 5. A.
The trophic levels can be explained as:1. In the trophic levels the energy gets decreased as it passes from one level to another because it is used in the cellular process it is released in the form of heat.
2. Secondary and tertiary consumers have to feed a lot and hence, they are fewer in number compared to the producers. They maintain the population and balance out the producer and consumer ratio.
3. According to the 10 % rule of energy transfer, the Tuna will receive 135 Kcal of energy because the energy decrease by 10% as one moves from the lower trophic to the upper levels.
4. The species that are non-native to a place or region are called invasive species hence, the Kudzu plant is the invasive species as it is introduced from Japan.
5. Given,
Energy of Seal = 2,500 Kcal
The energy of polar bear = 375 Kcal
The 10% of 2500 will be 250 and the 5 % 125 thus, 15% is the efficiency.
Therefore, the correct options are 1. C, 2. A, 3. A, 4. A and 5. A.

Explanation:
List and explain the 3 paths natural selection can take.
Answer:
1. Stabilizing Selection
2. Directional Selection
3. Disruptive Selection
Explanation:
Stabilizing Selection
This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed:
Example: For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.
Directional Selection
This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side:
Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.
Disruptive Selection
This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such:
Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.

D. Both A and B
The actual volume of bromine in each beaker will be same only the difference in height will be comparable. Therefore, option (C) is correct.
What are the properties of liquid ?A liquid's attributes are;
1) Compared to the volume occupied by a gas, the volume of a liquid is relatively stable at conditions that allow it to remain in the liquid state.
2) A liquid will take the form of the container it is placed in.
3) A liquid's surface in a container must be flat for the attraction forces between its molecules to be in equilibrium both at the liquid's surface and within its body.
Therefore, there will be variations in the measured height of the same volume of bromine in each beaker given that the volume of the bromine is measured in a 50 ml beaker and a 100 ml beaker.

As per the observation, it is clear that the correct answer is a medical book as it will have the medical history of the patient.
Gigantism is an extreme situation this is almost usually due to an adenoma, a tumor of the pituitary gland. Gigantism happens in sufferers who had immoderate boom hormones in childhood. The pituitary tumor cells secrete an excessive amount of boom hormone (GH), which main to many adjustments withinside the body.
How is gigantism diagnosed?If gigantism is suspected, the prognosis is commonly shown via way of means of taking blood assessments to degree the stages of boom hormone and insulin-like boom component 1 (IGF1) circulating withinside the blood. IGF1 is launched into the blood often via way of means of the liver in reaction to boom hormone.

Cancer is a condition when a few of the body's cells grow out of control and spread to other bodily regions.
In the millions of cells that make up the human body, cancer can develop practically anywhere. Human cells often divide (via a process known as cell growth and multiplication) to create new cells as the body requires them.
Occasionally, this systematic process fails, causing damaged or aberrant cells to proliferate when they shouldn't. Tumors, which are tissue masses, can develop from these cells. Tumors may or may not be cancerous.
