What is exothermic reaction?A heat-producing task is an exothermic process. This heat is conveyed to the external environment. Endothermic processes require heat to be supplied to the system from outside the system.
Exothermic reactions are heat-producing chemical reactions. When heat flows from the system to the surroundings, the heat flow q is negative. Exothermic reactions, therefore, have a negative enthalpy of reaction.
Thus, the correct option is B.

Which cell type undergoes terminal differentiation?
A-epithelial cells
B-stem cells
C-heart cells
D-hair cells
Stem cells are the cell type that undergoes terminal differentiation.
STEM CELLS:
Stem cells are cells in animals that are capable of differentiating into any cell type. Differentiation of a cell implies that the cell becomes more specific in its function. Stem cells undergo mitotic division to produce one daughter cell that is a stem cell and another daughter cell that has differentiated. Stem cells undergo terminal differentiation into specific cell types such as epithelial cells, muscle cells, heart cells, hair cells, blood cells etc. Therefore, stem cells are the cell type that undergoes terminal differentiation.Learn more at: https://brainly.com/question/11161299?referrer=searchResults

The variables in the study are the independent variable is fish tank, dependent variable is goldfish, and control is the water, fish food, and temperature.
What are experimental variables and control?
The experimental variables can usually one or several of the sample attribute categories which are used in study. It describes all the factors that differ between the test and the control samples in the study, which we are investigating. Example of experimental variable is disease.
The independent variable in an experimental study is what the scientists can change in the experiment. The dependent variable is what the scientist measures in the experiment, or the outcome of the study. The controlled variables are all the features which are kept the same throughout the experimental study.
The independent variable in the experimental study is the fish tanks, the dependent variable is the goldfish, and the control can be anything which remains same throughout the experiment is the water, fish food, temperature.

Explanation:
the all-or-none response of a neuron is similar to:
Answer:
The all-or-none law is a principle that states that the strength of a response of a nerve cell or muscle fiber is not dependent upon the strength of the stimulus. If a stimulus is above a certain threshold, a nerve or muscle fiber will fire.
The all-or-none response of a neuron is similar to a gun that either fires or doesn't. The correct option is B.
What is an all-or-none response?According to the all-or-none principle, signal transmission between neurons is solely dependent on the initial threshold being met rather than the stimulus's intensity.
In other words, neurons either fully or totally avoid transmitting an impulse via the synapse to the subsequent neuron.
According to the all-or-none law, the strength of a nerve cell's or a muscle fiber's response is not influenced by the stimulus's intensity.
A nerve or muscle fiber will activate if a stimulus is present above a predetermined threshold.
Therefore, the correct option is B. a gun that either fires or doesn't.

The chart below lists different plant species with a description of adaptations. Plant Species Adaptation Turkey Feet Grass This plant has very deep roots to prevent soil loss in windy areas, and to help anchor the plant. Pinkflower Hedgehog Cactus Contains spines for protection, and a waxy coating on the sunny side of the plant to help prevent water loss. Devil’s Walking Stick Secrete chemicals as a defense mechanism, and have broad leaves to catch sunlight in shady areas. Hairy Manzanita Pale pink flowers attract humming birds for pollination. Which plant species above is best adapted for a grassland biome? a Turkey feet grass b Pinkflower hedgehog cactus c Devil's walking stick d Hairy Manzanita
Answer:
A) Turkey feet grass
Explanation:
Grassland biome is one of the biomes that makes up the Earth's biosphere. Due to the characteristics of this biome (grassland), it favours the abundance of grass species over trees and shrubby plants. These characteristics include a low annual rainfall, soil's susceptibility to wind erosion etc.
Based on these characteristics, an organism that will thrive in this biome must be structurally adapted to it. This is the case of the Turkey feet grass mentioned in the question. The Turkey feet grass possess very deep roots to prevent soil loss in windy areas, and to help anchor the plant. This is as a result of soil loss common to the soil of grassland biomes.

Why do living things share fundamental characteristics
Answer:
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
Life processes are important to carry out daily life activities. They help to produce energy and maintain homeostasis in the body. The life processes help a body survive with the changes in the environment.
There are several fundamental characteristics or capacities that all living things share, including order, environmental sensitivity or responsiveness, reproduction, growth and development, regulation, homeostasis, and energy processing.
What fundamental characteristics share by living things?All living things share certain basic characteristics or functions, such as order, sensitivity to their environment, growth and development, reproduction, regulation, homeostasis, and the ability to process energy.
These characteristics work to define what it means to live. These characteristics collectively contribute to the definition of life. All of these characteristics will be found in living things.
All living things share the capacities to procreate, grow and develop, use energy, maintain homeostasis, respond to their environment, and be adaptable.
Therefore, all living things share fundamental characteristics.

Water fleas (Cladocera) are small freshwater crustaceans. They are filter feeders can are about 3-5mm long. The outer carapace of a water flea is transparent so the internal organs can be observed. Caffeine raises the heart rate of humans. Hanna predicts caffeine will have the same effect on other organisms. She uses the water flea as her test subject in an experiment. Hanna introduces varying amounts of caffeine to water flea populations. Using a microscope, she measures the heart rate in beats per second of sample water fleas. She records the data in a table. As the concentration of caffeine increases, Hanna observes the water flea heart rate also increases. What is the hypothesis in Hanna’s experiment? A) Caffeine raises the heart rate of humans. B) Water fleas prefer caffeine over plain water. C) Caffeine increase the heart rate of the water flea. Eliminate D) The effects of caffeine are the same on all organisms.
Answer:
The Answer is C.
Explanation:
sorry i took awhile
The hypothesis is the part of the scientific method that is the supposition based on some observed data. In Hanna's experiment, "caffeine increase the heart rate of the water flea" is the hypothesis. Thus, option C is correct.
What is a hypothesis?The hypothesis has been defined as the conjecture that is proposed in a scientific method and is based on the speculations from the observed facts and information. It is proposed to perform the experiment and reach the conclusion of the reliability.
They are testable and are performed through the experimental design that includes the experimental and control group so that the collected evidence can be analyzed and proved to be true. In Hanna's experiment, the effect of caffeine on the heart rate of fleas is a hypothesis.
It is a hypothesis as it is based on the observed fact that caffeine increases the human heart rate. The caffeine acted as the independent variable and the heartbeat was the dependent variable that showed that water fleas have increased heartbeat if given caffeine.
Therefore, option C. caffeine increases heartbeat is the hypothesis.
