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.

. Revisa las etiquetas de los alimentos que tengas en tu casa para ver si hay alguno vencido. ¿Qué le recomendarías a tu familia? ¿Por qué?
Answer:
Para comer alimentos sanos y frescos.
Explicación:
Recomiendo a mi familia los alimentos que aún no están vencidos o que son frescos porque los alimentos frescos hacen que nuestra condición de salud sea buena en comparación con los alimentos vencidos. Hay un crecimiento de patógenos como bacterias, hongos, etc.en los alimentos que los hacen dañinos para las personas y causan intoxicación alimentaria en las personas que los consumen, por eso tenemos que ver las etiquetas presentes en los alimentos para verificar su condiciones.

1. Compare gaseous biogeochemical cycle and sedimentary biogeochemical cycle.
Answer:
Gaseous cycles include those of nitrogen, oxygen, carbon, and water; sedimentary cycles include those of iron, calcium, phosphorus, and other more earthbound elements. In a sedimentary cycle elements move from land to water to sediment. Main reservoirs are the soil and sedimentary rocks.
Metabolic rate is _____. See Concept 40.4 (Page) View Available Hint(s) Metabolic rate is _____. See Concept 40.4 (Page) determined when the organism is vigorously exercising after consuming a fatty meal the total amount of energy an animal uses in a unit of time typically higher in an ectothermic animal than in an endothermic one the amount of heat gained by an animal in a unit of time directly proportional to body size
Answer:
The correct answer is ''the total amount of energy an animal uses in a unit of time''
Explanation:
The general metabolism or metabolic requirements can be defined as the energy demands that an organism requires for the set of biochemical reactions and physicochemical processes that occur in its cells. This set of reactions allows living beings to grow, reproduce, keep their physical structures in order and respond to external stimuli, among other things. Basal metabolism or Metabolic Rate (BMR) refers to the rate of energy expenditure (the amount of energy [expressed in kilocalories or megajoules (MJ)]) per unit of time that is spent when endothermic animals are in physical rest full. In other words, it is the amount of heat (expressed in calories) that is generated in one hour by an endothermic animal kept at rest. Also, it can be expressed as kilocalories per hour or per kilogram of weight.
This sea anemone and this ctenophora both have tentacles, which are body structures that help them catch food. However, sea anemone tentacles are short and can sting, while ctenophore tentacles are long for grabbing and cannot sting. What most likely explains why both species have tentacles and why the tentacles are different
Answer: Sea anemone and ctenophore both inherited tentacles from a shared ancestor population, but this population separated into different environments. In each environment, different types of tentacles evolved, which helped the populations survive.
Explanation:
most likely explains why both species have tentacles and why the tentacles are different is because sea anemone and ctenophore both inherited tentacles from a shared ancestor,
Then, this population separated into different environments and there was tye evolvement of different types of tentacles evolved, which therefore helped the populations survive.

A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.
What is cellular respiration?Glycolysis, the citric acid cycle, and oxidative phosphorylation are the three basic processes that take place during cellular respiration. The citric acid cycle happens in the mitochondrial matrix, oxidative phosphorylation happens on the inner mitochondrial membrane, and glycolysis happens in the cytoplasm.
Glucose, ATP, and NAD+ are the initial reactants and ATP and H2O are the end products of cellular respiration. The enzymes phosphofructokinase-1, pyruvate dehydrogenase, and isocitrate dehydrogenase control the rate of cellular respiration.
Disorders that interfere with cellular respiration often impair one or more of the enzymes necessary for it, such as succinyl-CoA synthase or pyruvate kinase.
Therefore, A sequence of chemical processes known as cellular respiration convert glucose into ATP, which can then be used as energy for a variety of bodily functions.

To be perfectly honest, I'm not sure what problem 32 is asking. It seems like there's set up to a question, but the actual question itself is missing.
=============================================
For problem 33, we divide the tape's distance by its time. I'm assuming that problem 33 is using the set up info from problem 32.
Recall that
distance = rate*time
we can rearrange things to say
rate = distance/time
So that's why we divide distance over time. The tape's length is effectively the distance, more or less. Imagine that one marker on the tape travels from one end of the reel to the other. It would have to travel the length of the tape when the full tape duration elapses.
----------
So,
rate = distance/time
rate = (260 meters)/(180 seconds)
rate = (260/180) meters per second
rate = 1.44 meters per second, which is approximate
I'm rounding to 3 sig figs.
CLAY PARTICLES DO NOT SETTLE DOWN EASILY DURING THE PROCESS OF SEDIMENTATION. CAN YOU SUGGEST ONE METHOD TO MAKE THEM HEAVIER AND THUS HELP IN SEDIMENTATION? Name the method and the chemical
Answer:
Coagulation by additionmof chemicals such as aluminium sulfate also known as alum will help in sedimentation of clay particles.
Explanation:
Clay particles are very small particles found suspended water obtained from streams and rivers for township supply. They have weak electrical negative charges on their surfaces which when they approach one another, they repel each other thus making it almost impossible for clay particles to settle out of suspension.
Because of this, prior to the sedimentation step, a chemical process known as coagulation is required. In this process, certain chemicals called coagulants, are added to the water to bring the difficult-to-settle suspended particles such as clay particles together into larger, heavier masses of solids called flocs. They do these by interfering with the repulsive forces between the particles, thus allowing them to clump together into flocs. The most commonly used coagulant used for water purification is aluminium sulfate or alum. Other chemicals that are also employed in coagulation include ferric sulfate and sodium aluminate.
How is the three-dimensional structure of type two collagen fibrils well-suited to their function during bone growth and development?
Answer:
Collagen is a hard, insoluble, and fibrous protein that makes up one-third of the protein in the human body. In most collagens, the molecules are packed together to form long, thin fibrils. These act as supporting structures and anchor cells to each other. They give the skin strength and elasticity.

Answer:
D.They carry human waste to treatment facilities away from cities.
Explanation:
Sewage system is a collection of systems that carries sewage (human waste) from the point it was produced to a place where it'll be treated or recycled.
Since sewage is moved via the use of sewage system, it helps to fight the spread of disease by carrying human waste (sewage) to treatment facilities away from cities.

A pair of butterflies reproduces and has one thousand offspring. All one thousand of the offspring have the alleles Aa. What is the most likely combination of alleles (genotype) for each parent? Explain your answer.
Answer:
It is expected that each parent is homo-zygous for each trait (i.e., one parent has genotype AA and the other parent has genotype aa)
Explanation:
An F1 hybrid is the first filial generation of the progeny of distinctly different parental types. In this case, it is expected that each parent is homo-zygous for each trait, thereby 100% of all offspring will have genotype Aa (i.e., parental cross: AA x aa >> F1 = 100% Aa). On the other hand, in a cross where one parent is heterozygous for the trait (Aa) and the other parent is homo-zygous (either AA or aa), only 50% of all offspring will have genotype Aa.

During his trip on the HMS Beagle, Darwin found that ______________.
A plants and animals living in temperate regions were most similar to each other, regardless of the continent on which they were found.
B fossils found on a particular continent were clearly not related to the plants and animals living on that continent today.
C plants and animals were similar on every continent and in every type of region.
D plants and animals living on one continent seemed more closely related to each other, than to plants and animals living in similar regions on other continents.
Answer:
Option D
Plants and animals living on one continent seemed more closely related to each other than to plants and animals living in similar regions on other continents.
Explanation:
From Darwin's discoveries, he noticed that there was a strong relationship between the environment and the characteristics of the living organisms present there. He proposed that the environmental conditions affected the development of certain traits in organisms present there, in their quest for survival and adaptation.
These traits were passed down from parents to offspring, producing a population of organisms with similar character traits found around the same geographical location (continent in this case)
