Answer:
Flat discs inside chloroplasts that are arranged in stacks are called (2) __thylakoids_. (3) __Pigments__ are light-absorbing substances that are inside chloroplasts. They absorb light of different (4) __wavelenghs__. The green pigment in plants that is essential for photosynthesis is (5) __Chlorophyll __. Light energy absorbed by this pigment excites (6) ____electrons___. They are transferred to a(n) (7) _Electron Carrier_. Then they move down an electron transport chain.
Explanation:
The chloroplasts are limited by an outer membrane and an inner one. In the middle of the two membranes, there is a space left called intermembrane space. In the interior of the inner membrane, there is another space known as the stroma. Within the stroma, there is the third system of membranes, known as thylakoids. They are disk-shaped structures, limited by a membrane, and in their interior, there is a space named thylakoid space.
Thylakoids are arranged as piles, receiving the name of grana. Grana connect to each other by a longer thylakoid membrane. The photosynthetic pigments are placed in the thylakoids, where it occurs light-dependent reactions. These molecules are in charge of light absorption. The most common pigment is chlorophyll, which provides the typical green color of plants. When sunlight reaches the pigments, electrons get excited and move along the electron transport chain, places in the thylakoid membrane. This process occurs during photosynthesis, while new electrons provided by water molecules replace the excited ones. The final products are oxygen, ATP, and NADPH.
In the stroma, it takes a place the Calvin cycle.

A number line going from 30 to 34. An open circle is at 32. Everything to the left of the circle is shaded.
Answer:
4.A number line going from 30 to 34. An open circle is at 32. Everything to the left of the circle is shaded.
Explanation:
It is given that the three-fourths of the employees at a bookstore came to a staff meeting. Less than 24 employees were at the meeting.
Let the total number employees be e.
Three fourth of the total employees is e, the total number of employees at the meeting were less than 24.
e < 24
Multiply 4 both sides.
ex 4 < 24×4
3e < 96
Divide both sides by 3.
e < 32
Therefore the value of e is less than 32.
In a number line as we approach towards left the the value of integers decreases.
Since the value of e is less than 32, therefore the solution graph is from negative infinity to 32.
Since 32 is not included in the solution set, therefore there is an open circle on 32.

Bears and salmon have a predator-prey relationship. What would most likely happen to the bear population if the salmon population increased?
stay the same
decrease
increase
become extinct
Answer:
Increase
Explanation:
When there is enough food there is always excelling Reproduction
Bears and salmon have a predator-prey relationship, if the salmon population increased, it is most likely that the bear population would increase; that is the third option, as bears rely heavily on salmon.
What is the predator-prey relationship?Bears are opportunistic feeders, and their diet varies according to what is available in their environment, and in areas where salmon is abundant, bears rely heavily on this food source to meet their nutritional needs. When salmon populations increase, there is a greater availability of food for bears, which can lead to improved body condition, increased survival rates, and higher reproductive success, and with more food available, female bears can produce larger litters of cubs.
Hence, bears and salmon have a predator-prey relationship, if the salmon population increased, it is most likely that the bear population would increase; that is the third option.

The growth of two plant saplings A and B, were observed for a period of 6 months. The graph shows the linear growth of the saplings, in centimeters.
Which sapling shows the greatest amount of growth during the 6 month time period? Explain.
Answer:
Sapling B
Explanation:
Since month 2 is the first month that is a point that has an ordered pair, you would take 10/2, which is, and Sapling A has its first full ordered pair at 50,3 then you would take 10/3, which is 3.3. So 5 is greater than 3.
where does reabsorbtion of glucose take place?
glomerulus
bowman's capsule
2nd coiled tubule
1st coiled tubule
Answer:
proximal tubule
Explanation:
Glucose reabsorption takes place in the proximal tubule of the nephron, a tube leading out of Bowman's capsule. The cells that line the proximal tubule recapture valuable molecules, including glucose.Under normal circumstances, up to 180 g/day of glucose is filtered by the renal glomerulus and virtually all of it is subsequently reabsorbed in the proximal convoluted tubule.

A. encourage the parents to keep the room quiet to allow him to sleep.
B. document it and plan to recheck him in an hour.
C. tell his parents to make him wake up because it is not time for him to go to bed.
D. realize that lethargy in an infant is always an ominous neurological sign and immediately assess him.
Answer:
D. realize that lethargy in an infant is always an ominous neurological sign and immediately assess him.
Explanation:
Lethargy in infants can be seen in several ways. one of this is that the child may be sluggish and as if he or she has little or no energy. the child may find it difficult to be awake for feeding. And can lose alertness and pays less attention to sounds and the baby is always drowsy. The registered nurse has to assess this baby immediately because lethargy could happen because the baby may have an infection or probably have low blood sugar. Therefore the last option is the best option for the nurse to take.

Which statement is true about a species living in a homogenous environment compared to a species living in a heterogeneous environment? A species that lives in a homogeneous environment is more likely to exhibit phenotypic plasticity. The homogeneity or heterogeneity of an environment does not determine whether a species will exhibit phenotypic plasticity. Only a large population in a homogeneous habitat can exhibit phenotypic plasticity. A species that lives in a heterogeneous environment is more likely to exhibit phenotypic plasticity.
Answer:
A species that lives in a heterogeneous environment is more likely to exhibit phenotypic plasticity.
Explanation:
Phenotypic plasticity might be understood as the ability of a genotype to produce different phenotypes in response to varying environmental conditions.
Phenotypic plasticity needs epigenetic mechanisms to occur, which involve the genotype and the environment interaction to produce adapted phenotypic changes.
Epigenetic mechanisms produce changes in the expression of the genes, with no need to alter the DNI nucleotides sequences.
A heterogeneous environment imposes variability on genotypes that interact with it, producing different phenotypes. These phenotypes will vary according to environmental conditions.

According to the National
Institute of Health, ventricular tachycardia is a fast, regular beating of the ventricles that may last for only a few seconds or for much longer. A few beats of ventricular tachycardia often doesn't cause
problems. However, episodes that last for more than a few seconds can be dangerous. Ventricular tachycardia can turn into other, more serious arrhythmias, such as ventricular fibrillation.
Based on the passage above, how will prolonged ventricular tachycardia affect blood pressure?
O It will increase blood pressure because the ventricles are contracting with more force.
O It will increase blood pressure because the ventricles are filling with more blood between beats.
O It will decrease blood pressure because there is a longer rest period beats of the ventricles.
O It will decrease blood pressure because the ventricles are filling with less blood between beats.
Answer:
It will decrease blood pressure because the ventricles are filling with less blood between beats.
Explanation:
In ventricular tachycardia, the heart beats faster than normal, usually 100 or ... The chaotic heartbeats prevent the heart chambers from properly filling with blood. As a result, your heart may not be able to pump enough blood to your body
