Answer: Glucose
The chloroplast during photosynthesis produce glucose under the light independent reactions. This happens due to some chemical reactions that convert carbon dioxide and other compounds into glucose. The process of these chemical reactions is called Calvin cycle, where it has three phases of light independent reactions, which are carbon fixation, reduction reactions and ribulose 1,5-bisphosphate (RuBP) regeneration. These reactions occurs in the stroma, the fluid filled area of chloroplast outside the thylakoid membrane.

The presence or absence of four limbs is not a useful character for studying evolutionary relationships among vertebrates, as it can be misleading. Other characteristics and genetic information should be considered to accurately determine evolutionary relationships.
Explanation:Reptiles are tetrapods that ancestrally had four limbs, but some species, like snakes, have secondarily lost or reduced their limbs over time. The presence or absence of four limbs is not a useful character for studying evolutionary relationships among vertebrates because it can be misleading. In the character table provided, the absence of four limbs in snakes does not necessarily mean they are more closely related to bass than to frogs, turtles, and leopards. It is important to consider other characteristics and genetic information to determine evolutionary relationships accurately.

Activation of the sympathetic division of the autonomic nervous system produces _____ in heart rate, and activation of the parasympathetic division produces _____.
a.increases, additional increases in heart rate
b.increases, decreases in heart rate
c.decreases, increases in blood pressure
d.decreases, additional decreases in heart rate
Final answer:
Activation of the sympathetic division of the autonomic nervous system increases heart rate for a 'fight or flight' response, while activation of the parasympathetic division decreases heart rate, supporting a 'rest and digest' state.
Explanation:
The autonomic nervous system, which includes the sympathetic and parasympathetic divisions, plays a crucial role in regulating the heart rate among other functions. Activation of the sympathetic division of the autonomic nervous system increases heart rate, preparing the body for 'fight or flight'. Conversely, activation of the parasympathetic division leads to a decrease in heart rate, facilitating a 'rest and digest' state. The sympathetic nerves release norepinephrine, which binds to adrenergic receptors causing an increase in heart rate. Parasympathetic nerves release acetylcholine, which binds to muscarinic receptors, resulting in a slowing of the heart rate.

Gene flow involves the spreading of alleles to and from a population. _______________ is the flow of genes into an area whereas _________________ is the flow of genes out of an area. A) immigration, emigration B) emigration, immigration C) founder effect, bottleneck effect D) bottleneck effect, founder effect
Answer: A) immigration, emigration
Explanation:
The gene flow can also be defined as the gene migration from one generation to another. The composition of the gene pool changes. Due to the genetic variability at the individual level the variation in the gene pool also increases. The gene flow occurs mainly because of migration of organisms from one region to another.
Immigration can be defined as the introduction of organisms in a new habitat. Emigration can be defined as the migration or departure of the organisms to a new habitat from their native habitat. Immigration will add new genes to the new habitat population gene pool. Emigration will limit the genetic variation in the gene pool.
On the basis of the above information, immigration is the flow of genes into an area whereas emigration is the flow of genes out of an area.
The specific heat of a metal is 0.5 cal/ (0C.g). The heat required to raise temperature of 100 gram of that metal by 20 0C is
The heat required to raise the temperature of 100 grams of the metal by 20 degrees Celsius is 1000 calories.
Explanation:The heat required to raise the temperature of an object can be calculated using the formula:
Q = mcΔT
where Q is the heat energy, m is the mass of the object, c is the specific heat of the object, and ΔT is the change in temperature.
In this case, the metal has a specific heat of 0.5 cal/(0C.g), which means it requires 0.5 calories of heat energy to raise the temperature of 1 gram of the metal by 1 degree Celsius. So, for 100 grams of the metal, the heat required to raise its temperature by 20 degrees Celsius is:
Q = (100 g) * (0.5 cal/(0C.g)) * 20 0C = 1000 cal
Therefore, the heat required to raise the temperature of 100 grams of the metal by 20 0C is 1000 calories.
Final answer:
The heat required to raise the temperature of 100 grams of the metal by 20 °C is 1000 calories.
Explanation:
The specific heat of a metal is a measure of how much heat energy is required to raise the temperature of a given amount of the metal by 1 degree Celsius.
The specific heat of the metal in question is given as 0.5 cal/°C.g.
To find the heat required to raise the temperature of 100 grams of the metal by 20 °C, we can use the formula:
Heat = mass * specific heat * change in temperature
Substituting the given values into the formula, we get:
Heat = 100 g * 0.5 cal/°C.g * 20 °C
Calculation
Heat = 100 g * 0.5 cal/°C.g * 20 °C
Heat = 1000 cal
Therefore, the heat required to raise the temperature of 100 grams of the metal by 20 °C is 1000 calories.

Answer:
chromatin
Explanation:
Chromatin (from the Greek chromatos, color) is a collection of strands, each formed by a long DNA molecule associated with histone molecules, a special type of protein. These wires are the chromosomes.
The chromatin filaments intersect eucromatin points with heterochromatin points. These two varieties of chromatin proceed differently according to the time of cell life. In the interphase, the segments of heterochromatin appear to be spiraled (similar to a telephone cord), while the segments of eurochromatin are distended. Thus, the chromonemas appear thicker and more colored at the heterochromatin points and are so thin that they are almost imperceptible at the level of the eurochromatin points.
