A researcher is testing young children to see if they can learn to associate a red circle with an event that the child enjoys. She sets up an experiment where a toy bear dances. The infants predictably love the toy bear and stare at it when it makes noise and dances. She then trains the child by showing a big red circle on a screen in front of the child and, immediately after that, the bear appears and dances off to the side. The bear is only visible right after the red circle appears and the child must turn his or her head to see the bear.
In this study, the unconditioned stimulus is ____________ baby does not turn head baby turns head dancing bear red circle , the unconditioned response is the __________ dancing bear baby does not turn head red circle baby turns head , the conditioned stimulus is the _________ dancing bear baby turns head baby does not turn head red circle , and the conditioned response is the ______ baby does not turn head red circle dancing bear baby turns head . The neutral stimulus is the _______ baby turns head dancing bear red circle baby does not turn head and the response to the neutral stimulus is the 6 _______
Answer: unconditioned stimulus = dancing bear
unconditioned response = baby turns head
conditioned stimulus = red circle
conditioned response = baby turns head
neutral stimulus = red circle
response to neutral stimulus = baby does not turn head
Explanation:
The unconditioned stimulus is the stimulus that occurs naturally without any prior learning.
The unconditioned response refers to an unlearned response which happens naturally and which occurs due to the unconditioned stimulus.

How does environmental factors affect variation
Answer:
Environmental causes of variation
Characteristics of animal and plant species can be affected by factors such as:
climate
diet
accidents
culture
lifestyle
For example, you will become heavier if you eat too much food, and you will become lighter if you eat too little. A plant in the shade of a big tree will grow taller as it tries to reach more light.
Answer:
Many factors can contribute to growth variation across and among populations such as genetic factors, nutrition, environmental conditions, social conditions, and cultural conditions ,Internal and external environmental factors, like gender and temperature, influence gene expression. Similarly, drugs, chemicals, temperature, and light are among the external environmental factors that can determine which genes are turned on and off, there by influencing the way an organism develops and functions.
During a recent hurricane, 25 individuals of the same butterfly species were blown onto a barrier island in southern Florida. Prior to this event, this species did not inhabit the island, but with the ample vegetation on the island and a lack of predators, the displaced individuals were able to survive and reproduce. When the butterflies initially arrived on the island, they did not have to compete for food or space. What type of population growth did they likely exhibit
Answer: Exponential
Explanation:
The main requirement for the population of a species to grow is food. When there is food, a organisms that are born will be able to live longer because food will be able to sustain them.
This is what happened with humans during the Neolithic Revolution when we began farming.
The general trend is that the more food that is available, the higher the population growth. When these butterflies arrived and found no competition for food, their population would increase in the highest way possible which is exponentially because there would be plenty of food to go around.
Answer:
Exponential growth
Explanation:
Without any competition for food or space, the butterfly species likely experienced exponential growth.
The lack of competition would have allowed the population to flourish, as they would have excess amounts of resources, food, space, and other limiting factors.
So, they most likely exhibited exponential growth.

What type of cells are simple animal and plant cells?
Answer:
both animals and plants are eukaryotic cells
Answer:
Animal cells have centrosomes (or a pair of centrioles), and lysosomes, whereas plant cells do not. Plant cells have a cell wall, chloroplasts, plasmodesmata, and plastids used for storage, and a large central vacuole, whereas animal cells do not.
Explantion
Animal cells
Animals are made up of millions of cells. Animal cells have an irregular structure and are made up of four key parts:
Nucleus – This contains genetic material (DNA), and controls the cell's activity.
Cell membrane – A flexible layer that surrounds the cell and controls the substances that enter and exit.
Cytoplasm – A jelly-like substance where the chemical reactions happen.
Mitochondria – This is where energy is released from the food molecules
Plant cells
Plants are also made up of millions of cells. Plant cells have a nucleus, cell membrane, cytoplasm and mitochondria too, but they also contain the following structures:
Cell wall – A hard layer outside the cell membrane, containing cellulose to provide strength to the plant.
Vacuole – A space inside the cell that is used to store substances and help the cell keep its shape.
Chloroplasts – Structures that contain the green pigment chlorophyll, which are a key part of photosynthesis.

Why does climate change affect so many things?
Answer:
These have been caused by many natural factors, including changes in the sun, emissions from volcanoes, variations in Earth's orbit and levels of carbon dioxide (CO2). Global climate change has typically occurred very slowly, over thousands or millions of years.
Explanation:
According to me there are several causes of climate change, but all the problems are based upon a major problem which is over population. Either it is deforestation, any kind of pollution, global warming or whatever it is, all these problems are inter-linked and all are due to increasing population.
What is a disadvantage of using a space-filling model to show a chemical compound?
Answer:
Explanation:
The appropriate answer is 'space filling models do not identify the number and type of bonds'. A space filling model is one type of three dimensional (3D) molecular model used to represent molecules of different chemical compounds. The structure of this type of arrangement shows that, for example, two elements are bonded but it does not show if it is a single, double or triple bond.

In the process of photosynthesis, _______ in autotrophs convert solar energy into chemical energy and store this 'food' for later use. The reaction for photosynthesis is: 6CO2(g) + 6H2O(l) + energy --> C6H12O6(s) + O2(g). In the process of ________, mitochondria in the cells of plants, animals and other multicellular organisms break down 'food' molecules to generate molecules of _______ . This is the source of energy for all cellular functions. The reaction for cellular respiration is: ________
ATP
chemosynthesis
chloroplasts
cellular respiration
NADPH and FADH2
C6H1206(s) + 02(g) -- CO2(g) + 6H20(I) + energy
Answer:
1. Chloroplast
2. cellular respiration
3. ATP
4. C6H1206(s) + 02(g) -- CO2(g) + 6H20(I) + energy
Explanation:
This question is describing the processes of photosynthesis and cellular respiration. Photosynthesis occurs in the CHLOROPLAST, which is responsible for the conversion of solar energy (from sun) into chemical energy (in glucose). The general photosynthetic reaction is:
6CO2(g) + 6H2O(l) + energy → C6H12O6(s) + O2(g)
Contrarily, the process of cellular respiration occurs in the MITOCHONDRIA. Cellular respiration involves the breaking down of food molecules to synthesize ATP (energy) for use during biochemical reactions. The general chemical reaction is as follows:
C6H1206(s) + 02(g) → CO2(g) + 6H20(I) + energy
1 Reproduction is an important characteristic of living organisms.Explain
Answer:
Reproduction is one of the most important characteristics of living beings, because -
- The existence of any species is dependent on the reproduction because no living being is immortal.
After death of a being of one generation,the existence of that died being is completed by the newborns of the next generation.
And,the birth of newborns of next generation is only possible by the reproduction.
- The variation and mutation in the biological characteristics is often necessary which is only possible by reproduction through many generations.
- When a living being becomes old, it's become unable to do normal tasks like collection of food, finding shelter etc,at that moment,the newborns of next generation do the necessary jobs.
And as mentioned before,these newborns are only possible due to reproduction.

Which of the following is a normal process of photosynthesis that could not occur if all reaction centers were inactivated by a toxin?
A. donation of excited electrons by chlorophyll a to a primary electron acceptor
B. absorption of photons by chlorophyll b
C. absorption of photons by carotenoids
D. donation of excited electrons by chlorophyll b to a primary electron acceptor
Answer:
A. donation of excited electrons by chlorophyll a to a primary electron acceptor
Explanation:
Photosystems are structures located at the thylakoid membrane that act to harvest energy light in order to convert it into chemical energy. Each photosystem is composed of a light-harvesting complex and a core complex, which in turn is composed of a reaction center. The photosynthetic reaction centers are multi-protein complexes that use light energy to catalyze the electron transfer across the chloroplast thylakoid membrane against a thermodynamic gradient. Moreover, antenna pigments are pigments that capture the energy from photons in order to transfer energy to other pigments in the photosystem (e.g., chlorophyll B and carotenes are antenna pigments, whereas chlorophyll A is the core pigment). Light energy absorbed by antenna pigments in the photosystems is transferred to the reaction center chlorophyll A molecules, thereby exiting electrons in the reaction center. A reaction center consists of two chlorophyll A molecules, which donate electrons to the primary electron acceptor.

Identify the incorrect statement regarding the fundamental causes of edema. Multiple Choice Capillary reabsorption does not depend on oncotic pressure. A deficiency of albumin (hypoproteinemia) produces edema by reducing the reabsorption of tissue fluid. Kidney failure leads to water retention and hypertension, thus raising capillary blood pressure and filtration rate. Obstruction of lymphatic vessels can interfere with fluid drainage and lead to the accumulation of tissue fluid distal to the obstruction. Since albumin is produced by the liver, liver diseases, such as cirrhosis, tend to lead to hypoproteinemia and edema.
Answer:
Capillary reabsorption does not depend on oncotic pressure
Explanation:
Edema refers to the swelling caused by the fluids trapped in the body's tissues, which swell from injury and/or inflammation. Edema can be associated with the decrease in plasma oncotic pressure, i.e., osmotic pressure exerted by proteins (especially albumin) in the blood vessel's plasma, the increase in hydrostatic pressure, or the increase in the capillary permeability. Moreover, capillary reabsorption refers to the movement of fluid from interstitial space to the capillaries, which is driven by the blood colloidal osmotic pressure. Lymphatic obstruction, i.e., the blockage of the lymph vessels that drain fluids from tissues, may cause edema in the part that is drained by the affected vessels (it is known as lymphedema). Moreover, liver/kidney failure may lead to edema by decreasing albumin and oncotic pressure. When plasma albumin levels drop because of liver diseases, the colloid osmotic pressure also decreases. In consequence, liver diseases, including stage 3 cirrhosis, lead to the development of swelling in the abdomen, thereby leading to edema.
