A new species is discovered and scientists are trying to classify it. One of the key features found is that the species is entirely dependent on other organisms for its food necessary to sustain life. What type of species is this?
Answer:
Parasitic
Explanation:
The species that is described is a parasitic species. The reason why it will fall into this category is that its key feature is that it is entirely dependent on other organisms for its food. This type of species are not able to produce food for themselves, nor are able to get it from the environment, which is way they have evolved in a manner to use the other organisms. They find a host organisms, attach to it, and then they are extracting the nutrients out of that organism, thus classical parasitism. The extraction of the nutrients can be so severe that the parasitic species can actually kill systemically its host.

Philippe wants to measure how much water his potted tomato plants lose through transpiration each day. To do this, he sets up a series of experiments to capture the water that leaves the plants. Which of these experiment designs would BEST measure the amount of water lost through transpiration? Text to speech
A.Enclosing the plant’s roots in plastic to collect the water transpired by the plant.
B.Enclosing the plant in plastic so that any water lost through transpiration could be collected.
C.Placing the tomato plant inside a dark corner where the rate of transpiration would be slow and easy to measure.

Krista has been watching a heavy rainfall outside. After the storm, she walks out and notices that there is no water in the gravel driveway, some water in the grassy yard, and a standing puddle in the hard-packed dirt in the corner of the yard. What statement BEST explains Krista’s observations? Text to speech
A.The infiltration rate of the gravel is faster than that of the grassy area, which is faster than the hard-packed dirt.
B.The infiltration rate of the gravel is slower than that of the grassy area, which is slower than the hard-packed dirt.
C.Less precipitation fell on the gravel driveway than on the grassy area, which had less precipitation than the hard-packed dirt area.
D.More precipitation fell on the gravel driveway than on the grassy area, which had more precipitation than the hard-packed dirt area.
Transitions from condensed water to crystallized water and back again occur often in nature. Such transitions are particularly frequent in winter. Below are parts of a model that help illustrate this idea. Which statement makes the best caption to explain the role of energy in this model?
A.Energy is released during both transitions.
B.Energy is absorbed during both transitions.
C.Water loses energy during crystallization and gains energy during melting.
D.Water gains energy during crystallization and loses energy during melting.
1. The correct answer is B.
Blatantly increasing or decreasing the rate of transpiration is not an accurate way to measure the typical amount of water that is lost through transpiration, which eliminates choices C and D. The method proposed in choice B is pretty wrong and will lead to the collection of no water.
For the second question, the correct answer is A. The prompt mentioned that the dirt area contained the most water, which automatically eliminates choices B and D. What makes choice C wrong is that the water reached the materials in equal amounts, but some of them were able to infiltrate the water faster. Hard-packed dirt will, due to its thickness, always take the longest to infiltrate water.
For the third question, we know that energy is required to melt things -- thus eliminating choices B and D. Because the energy is being used, it would have to lose some energy and not gain any back unless you're melting something. The difference between choices A and C is that HEAT is released during crystallization...only! In order for something to melt, heat/energy must be taken in. So, the correct answer is C.
The best method to measure water loss through transpiration in plants is to enclose the plant in plastic, which allows for the collection of transpired water vapor. The infiltration rate of different surfaces explains the presence of water after rain. Water transitions between phases involve losses and gains of energy, depending on the process.
Transpiration is a vital process for plants, allowing them to absorb water from the soil and maintain homeostasis. The process involves the loss of water vapor from the stomata in the leaves. Understanding the transpiration process is critical to measuring the water loss from plants accurately.
To measure the amount of water lost through transpiration by Philippe's potted tomato plants, the best experimental design would be choice B, enclosing the plant in plastic so that any water lost through transpiration can be collected. This method effectively captures the water vapor transpired by the plant and condenses it on the plastic, allowing for measurement.
Regarding Krista's observations after the rainfall, the most accurate explanation is statement A. The infiltration rate of the gravel is faster than that of the grassy area, which is faster than the hard-packed dirt, indicating the varying ability of these surfaces to absorb water.
Finally, when discussing the transitions from condensed water to crystallized water back and forth in nature, such as during winter months, the proper explanation involving energy is statement C. Water loses energy during crystallization and gains energy during melting. This explains the energy change associated with the phase transitions of water.

The recycling truck comes every Friday to gather what has been put into the trash cans. This is similar to _______ in eukaryotic cells.
The recycling truck's function of gathering waste is analogous to lysosomes in eukaryotic cells, which act as recycling centers with enzymes that break down biomolecules and old cellular components for reuse.
The recycling truck's role in gathering and carrying away waste for recycling is similar to the function of the lysosome in eukaryotic cells. Lysosomes are like the recycling centers of cells because they contain digestive enzymes that break down various biomolecules and old cellular components into their basic parts. These parts can then be reused by the cell to build new molecules or to produce energy. This process is critical in maintaining cellular health by removing damaged or non-functional components and recirculating their building blocks. The enzymes within the lysosome operate at a lower pH, which is more acidic than the rest of the cell, allowing these enzymes to efficiently break down materials without impacting other cellular processes.
Were there more producers than consumers and more consumers than predators on your pyramid? Why or why not? Were there any that could have fit in more than one category?
Answer:
If there is no grain available for the mouse the mouse population would die because it would have lost its main food source then the predator of the mouse would have less food resulting in a decrease in population
Explanation:
Answer:
Pyramid -"It is series of levels on which the different organisms are characterized on basis of there ecological levels or properties relating energy consumption or creation."
As some are producers which carry out while using various metabolic pathways to create energy for the whole biosphere or as whole for all the livings begins. As there are other organisms who consumes the energy created in the system or bio-sphere.
Explanation:
Pyramid (Ecological level)
So, the producers must be in large in number in the ecological level, so, that can be able to create more energy for the entire population of different specie to survive and sustain there body mechanism. And the consumers are there in low in number, due to the reason that there can be little to no scarce of energy. As energy created will be finished in no time,if the consumers are more in number as compared to the producers present on the lower level of the pyramid.Example:
If due to some reason, the producers at lower level become less in number, then there will be no grass available for the whole livestock population, which will obviously leads to decrease in its total population. As it will be also alarming for the consumers population at upper ecological level,which are also present at a high number or increasing population.Certainly life will be at risk on Earth if the number of producers creating the energy for survival of beings decreases at lower level of the pyramid.

Where are subduction zones likely to form?
A. Between two diverging oceanic plates
B. Between diverging oceanic and continental plates
C. Between two diverging continental plates
D. Between converging oceanic and continental plates
Answer:
B. Between converging oceanic and continental plates
Explanation:
Subduction happens when a tectonic plate slides under another one.For this to occur, the two plates have to be converging towards each other.
Answer:
Option D, Between converging oceanic and continental plates
Explanation:
Subduction zones/boundaries are formed in the regions in which one tectonic plate slips below the other tectonic plates. These tectonic plates could be a pair of oceanic/continental plates or one oceanic and one continental plate.
In a converging process, two tectonic plates move towards each other until they collide thereby causing slipping of one plate below the other. While in a diverging process, the two tectonic plates move away from each other and hence there is no chance of formation of subduction zone.
Thus, option D is correct.

Carry nerve impulses to the brain from skin and other sensory organs D. Carry nerve impulses from the brain to skin, glands, and muscles
Answer:
The correct answer option is D. Carry nerve impulses from the brain to skin, glands, and muscles
Explanation:
Motor neurons carry signals out of the Central Nervous System (CNS).
These motor neurons have long extensions called axons which spread from the CNS to the muscles that connect with the innervate.
The information from the brain to the muscles and other glands is sent in the form of electrical impulses via the spinal cord.
D. Motor neurons carry nerve impulses from the brain to skin, glands, and muscles describes the function of motor neurons. Option D is correct.
Motor neurons are a type of nerve cell that play a crucial role in the transmission of nerve impulses from the central nervous system (CNS) to the body's effectors, which include muscles, glands, and some organs. They are responsible for initiating and controlling voluntary movements and other motor functions.
Option D accurately describes the function of motor neurons. These neurons transmit signals from the brain and spinal cord, collectively known as the CNS, to the peripheral nervous system (PNS) and its effectors. The nerve impulses generated in the brain travel down the spinal cord and are then transmitted through motor neurons to reach their target muscles, glands, or skin cells.
By carrying these nerve impulses, motor neurons enable voluntary muscle contractions, allowing us to move our limbs, perform actions, and control the movements of our skeletal muscles. They also play a role in regulating glandular secretions and controlling the response of smooth muscles in organs.
Options A, B, and C do not accurately describe the function of motor neurons. Option A refers to autonomic neurons, which control involuntary functions of organs like the heart, while option B refers to interneurons that transmit information within the CNS. Option C refers to sensory neurons, which carry nerve impulses from sensory organs to the brain.
In summary, motor neurons are responsible for transmitting nerve impulses from the brain to muscles, glands, and skin. They play a critical role in enabling voluntary movements and controlling various motor functions in the body.

Answer:
The mechanism of enzyme action.
Explanation:
The lock and key mechanism refer to the mechanism of enzyme action. The enzyme is a bio catalyst which enhance the biochemical reactions without changing itself. In the lock and key mechanism, a specific substrate will attach to the active site of the enzyme to form an enzyme-substrate complex. It's like a specific key fits with the lock. The active site is the portion of the enzyme, where it gets attached to the substrate. Then the substrate becomes the product and detaches from the enzyme. Now the enzyme becomes free and another specific substrate will attach to carry on the enzyme action.
