Answer:
lichens, hearty shrubs, trees
Explanation:
Order:
I-bare rocks,
II-pioneers (mosses, lichen, algae, fungi)
III-annual herbaceous plants
IV-perennial herbaceous plants and grasses
V-shrubs, VI-shade intolerant trees, VII-shade tolerant trees.
(please mark me brainliest) :)
Lichens, hearty shrubs, and trees is the correct order in which the organisms return to an ecosystem during primary succession after an area's ecosystem has been wiped out. Thus, the correct option is C.
What is Primary Succession?Primary succession is the ecological succession which begins in essentially the lifeless areas, such as the regions in which there is no soil or where the soil is incapable of sustaining life where no life form ever existed because of recent volcanic eruption, newly formed sand dunes, or rocks that are left from a retreating glaciers.
The correct order of the Primary Succession is:
Stage I- Bare rocks,
Stage II- Pioneer species such as mosses, lichen, algae, and fungi
Stage III- Annual herbaceous plants
Stage IV- Perennial herbaceous plants and grasses
Stage V- Shrubs, shade intolerant trees, and shade tolerant trees.
Therefore, the correct option is C.

Cuales son algunas de las propiedades que comparten las ondas electromagnéticas infrarrojas y la luz visible? En que son diferentes? Ayuda porfavor :(
Answer:
ver explicacion
Explanation:
Las ondas electromagnéticas a menudo se denominan colectivamente luz. Se sabe que todos viajan a través del espacio y poseen una velocidad de 3 × 10 ^ 8 m / s.
Como ondas, tanto la luz visible como la radiación infrarroja comparten propiedades comunes como refracción, difracción, interferencia, etc.
Sin embargo, la principal diferencia entre los rayos infrarrojos y la luz visible es que la luz visible se puede ver a simple vista, mientras que los rayos infrarrojos no se pueden ver a simple vista.
Explain how the body prevents particles in inspired air from reaching the gas
exchange surfaces.
Your respiratory system prevents harmful substances from entering the lungs by using: .Mucus produced in the trachea and bronchial tubes to keep air passages moist and aid in intercepting dust, bacteria and other substances; The sweeping motion of cilia (small hairs in the trachea) to keep air passages clean
Mucus produced in the trachea and bronchial tubes to keep air passages moist and aid in intercepting dust, bacteria and other substances; The sweeping motion of cilia (small hairs in the trachea) to keep air passages clean.
What is inspired air?Due to exchanges that occur in the alveoli, the amount of gases in the air that is breathed in and out varies. We only take in about 4 to 5 percent of the oxygen found in atmospheric air, and we exhale air with about 16% oxygen.
Normal air contains about 0.04% carbon dioxide, and as it diffuses from the blood into the alveoli, we exhale air with about 4% carbon dioxide. Exhaled air is hotter than that which we breathe in and includes more water vapor than that which we breathe in.
In contrast to ordinary smell, which occurs during the inhalation phase, the olfactory contribution to flavor occurs during the exhalation process. As a result, we can conclude that expired air differs from inspired air in terms of oxygen content, bacterial density, and water vapor content.
Therefore, Mucus produced in the trachea and bronchial tubes to keep air passages moist and aid in intercepting dust, bacteria and other substances; The sweeping motion of cilia (small hairs in the trachea) to keep air passages clean.

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

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.

C. Where the nasal passages meet the air
D. Where are the alveoli meet capillaries
Answer:
The Answer is Option D.
Exchange of respiratory gases, oxygen and carbon dioxide take place in the alveoli of the lungs. Oxygen which is inhaled from the atmosphere diffuses through the walls of the alveoli and reaches to the adjacent capillaries into the red blood cells.

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.

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.
