Which cells are considered excitable cells because they are able to produce electrical signals?

Answers

Answer 1
These are excitable and action potential cells, because when they receive a stimulus they activate an action potential, these stimuli are electrical, chemical, mechanical and photonic. The action potential changes rapidly in the membrane potential in response to a stimulus and returns a resting potential. The action potential has several stages, and its main characteristics are that nothing is produced or produced when generated is maintained and propagated, the time of the voltage-dependent channels remain open. The types of the action potential are spike potential, plateau potential, potential and rhythmic potentials.

Answers

I got only 1 answer wrong on Biology so i chose co-evolution.

Answer:

Coevolution

Explanation:

Coevolution is the process of reciprocal adaptation of two or more species or populations due to their close interaction for a longer period of time. It is a mutual adaptation and occurs by development of certain morphological and behavioral features in each of the species. Increased efficiency of Newt's poison is rendered less harmful by garter snake as they develop more resistance for it.

Neurons communicate with other neurons and stimulates effector cells which includes both blank and blank?

Answers

"muscle cells" and "gland cells"
In this context, an effector cell is a cell that's at the terminal end of an efferent nerve fiber and therefore is capable of receiving a stimulus and responding to it. An efferent nerve fiber (or motor fiber) is one that carries information from the central nervous system.

Neurons use electrical and chemical signals to communicate with other neurons and with effector cells, which are muscle cells and glands. They do so through synapses where neurotransmitters are released to convey signals.

Neurons communicate with other neurons and stimulate effector cells which includes both muscle cells and glands.

Neurons are excitable cells capable of creating tiny electric currents to transmit signals. They consist of dendrites, a cell body, and an axon. The dendrites carry information toward the cell body, and then the signal travels along the axon to reach either another neuron or an effector cell. At the point of contact, which is the synapse, neurotransmitters are released to convey the signal to the next cell. Muscle cells and glands are common targets for these signals, ultimately resulting in motion or secretion, respectively.

The communication between neurons, and from neurons to effector cells, is essential for the nervous system to control body functions, ranging from the simple reflex action to complex behaviors and cognitive processes.

Help appreciated! Compare and contrast critical thinking and an inference.

Answers

Critical thinking and inferences are both ways to come to a conclusion or decision. Both are used in everyday life to come to a decision about a particular situation. An inference is more similar to an assumption though. You don't spend as much time considering all aspects of the situation. An inference is more of a quick decision. When you engage in critical thinking, you consider all aspects of the decision. Critical thinking would take more time.

Predict which responses would occur in cells exposed to the a+b signaling molecules

Answers

Cell responses b and c would both occur when cell exposed to the a+b signaling molecules. The presence of the C signaling molecule will lead to cell response c. Cell response b occurs because the activation of c2 in the C pathway stimulates b1, leading to cell response b. Cell response A remains inactivated because it is inhibited by pathway b activation and its signaling molecule was not present.

what are the three main parts of the scientific process?
a) predicting, inferring , and drawing conclusions
b) activating knowledge, and inferring
c) observation, experimentation, and scientific
d) data collection, analysis, and hypothesis formation

Answers

Should be C.You have to observe first

The scientific process consists of three main parts: observation, experimentation, and scientific reasoning.

Option (c) is correct.

Observation involves gathering information about a phenomenon or a problem through the senses or using instruments. It is the first step in the scientific process and provides the foundation for further investigation.

Experimentation involves designing and conducting controlled experiments to test hypotheses or theories. Through carefully planned experiments, scientists manipulate variables and collect data to analyze and draw conclusions.

Scientific reasoning is the process of analyzing data, evaluating evidence, and drawing logical conclusions based on the results of experiments. It involves critical thinking, interpreting data, and identifying patterns or relationships.

The scientific process is an iterative and ongoing cycle. After drawing conclusions, scientists often refine their hypotheses and design new experiments to further investigate the topic or expand knowledge in the field.

While options a), b), and d) touch upon aspects of the scientific process, option c) provides a more comprehensive and accurate representation of the main components involved in scientific inquiry.

Given: 
She heard that plants compete for space and decided to test this idea.
She bought a mixture of flower seeds and some potting soil.
She put the same amount of soil into each of 5 plastic cups.
1st cup she planted 2 seeds
2nd cup she planted 4 seeds
3rd cup 8 seeds
4th cup she planted 16 seeds.
5th cup she planted 32 seeds.

After 25 days, she determined which set of plants looked the healthiest.

1 independent variable - NUMBER OF SEEDS PLACED IN A CUP
2 Dependent variable(DV) - APPEARANCE OF THE PLANTS
3 Controlled variables - SOIL PLACED IN EACH CUP
4 Hypothesis - If there is more space that a seed can grow then the healthier the plant is and vice versa.

Answer:

The correct answer will be -

1.  Independent variable - the number of seeds

2. Dependent variable - growth of the plant

3. Controlled variables - amount of soil

4. Hypothesis - plant growth is directly proportional to the provided space.

Explanation:

In a scientific experiment, the variables could be categorized as dependent variables(to be studied),  independent variables (can be manipulated) and constant (kept constant).

A scientific hypothesis is the prediction or an idea based on the previous work and observations which could be tested to answer the question.

In the given question, the variables to be tested is growth of the plants while the variables which can be manipulated is the number of seeds. The variable kept constant is the amount of soil added to the cups and the hypothesis will be the plant growth is directly proportional to the provided space.

How does water's specific heat relate to its usefulness for life give examples?

Answers

Water covers around 70% of the Earth's surface and its high specific heat plays a very important role as it is able to absorb a lot of heat without a significant rise in the temperature. When temperatures decrease, the heat which is stored is released, restraining a rapid drop in temperature. The combined effect of these processes is a buffering of temperature on the Earth.

Water's high specific heat stabilizes temperature, vital for organisms' survival, regulates body temperature, and influences climate patterns.

Water's high specific heat, defined as the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius, is crucial for life on Earth. This property enables water to absorb and store large amounts of heat energy with minimal temperature change, thereby moderating temperature fluctuations in the environment and providing thermal stability.

In biological systems, this thermal stability is essential for maintaining relatively constant internal temperatures, which is vital for the proper functioning of organisms.

For example, in humans, water's high specific heat helps regulate body temperature, preventing rapid overheating or cooling. Additionally, aquatic ecosystems benefit from water's ability to absorb and retain heat, maintaining relatively stable temperatures in rivers, lakes, and oceans, which is crucial for the survival of aquatic organisms.

Moreover, water's high specific heat also plays a role in climate regulation on a global scale. The oceans act as heat reservoirs, absorbing excess heat from the atmosphere during the day and releasing it at night, thereby influencing weather patterns and climate conditions. Overall, water's high specific heat is a fundamental property that contributes to the suitability of Earth for life as we know it.
