So Thank You
After pioneer plants begin their role in the process of ecological succession, the most likely organism to follow is shrubs.
What do you mean by Ecological succession?Ecological succession may be defined as the gradual and continuous replacement of one species by another over a specific period of time.
After the primary succession occurs, the pioneer species are evolved, and due to this, the process of ecological succession carries forward. These pioneer species are generally plants that performed photosynthesis.
Therefore, after pioneer plants begin their role in the process of ecological succession, the most likely organism to follow is shrubs.

Which is one piece of information that astronomers use to calculate the age of the universe?
dark energy
the age of rocks on Earth
the current motion of inner planets
patterns of background radiation
Answer:
d
Explanation:
The patterns of background radiation are information that astronomers use to calculate the age of the universe. Therefore, the correct statement is option D.
What is CMB radiation?Big Bang theory gives evidence about cosmic microwave background radiation that filled the early universe. The CMB radiation has uniformity in all directions, but it has slight temperature variations.
These variations are the result of small fluctuations in the density of matter in the early universe, which results in the formation of galaxies and other structures.
The patterns of these temperature variations are studied and astronomers learn about the properties of the early universe to make calculations about the age. They can use CMB radiation for estimation of the amount of time passed since the universe began expanding rapidly in the aftermath of the Big Bang.
Therefore, the patterns of background radiation provide very important information from which astronomers can calculate the age of the universe which is estimated to be about 13.8 billion years old.

The surface area and volume for four cells are given. Which combination of cell dimensions would be considered the MOST metabolically favorable?
A. cell 1: surface area 14 mm^2, volume 33 mm^3
B. cell 2: surface area 20 mm^2, volume 12 mm^3
C. cell 3: surface area 7 mm^2, volume 17 mm^3
D. cell 4: surface area 5 mm^2, volume 2 mm^3
Answer:
D
Explanation:
This is because a bad ratio would be one where the volume is larger than the surface area. Once a cell's volume is larger than the surface area, there's not enough surface area to process all the products coming in and waste coming out. Ideally, you'd want a surface area and volume to be as close to each other as possible in number, but you'd rather have the volume be less than the surface area.

predict whether a pot of water heated from the top would boil more quickly than a plt of water heated from the bottom. Explain your answer.
Water will boil faster when it is heated from the bottom rather than when it is heated from the top.
The boiling of water occurs due to convection currents. Heavier particles moves from upwards and travels downwards and then they are replaced by lighter particles traveling upwards. This is called convection currents.
As such, water will boil faster when it is heated from the bottom rather than when it is heated from the top.

We cut the celery stem under water to see the color change in the stem due to movement of water through the process of transpiration in the cell.
What is Celery stem?Celery stalks or stems are the petioles of the compound leaves. They are not the stems, in spite of the widespread misrepresentation in elementary school lesson plans only. They may also look like the stems to some people because they are thick and fleshy due to accumulation and have prominent veins which are running lengthwise through them.

Based on the equation for Hardy-Weinberg equilibrium, the expected number of wolves with the FBFB genotype is 12.
Based on the equation for Hardy-Weinberg equilibrium, the expected number of wolves with the FBFW genotype is 40.
Based on the equation for Hardy-Weinberg equilibrium, the expected number of wolves with the FBFW genotype is 96.
The population is not at Hardy-Weinberg equilibrium. The population may be evolving because the actual number of individuals with each genotype differs from the expected number of individuals with each genotype.
Answer: Based on the equation for Hardy-Weinberg equilibrium, the expected number of wolves with the FBFW genotype is 96.
Based on the equation for Hardy-Weinberg equilibrium, the expected number of wolves with the FBFB genotype is 12.
The population may be evolving because the actual number of individuals with each genotype differs from the expected number of individuals with each genotype.
The population is not at Hardy-Weinberg equilibrium.
Explanation:
The FB allele should accounts for 120 of the alleles (40 × 2 = 80 in FBFB wolves, + 40 × 1 = 40 in FBFW wolves).
the FB allele would make up 20% (120/600) of the total alleles in the population, so the value of p would be 0.2. The allele frequencies of the population must add up to one for it to be valid (what this means is p+q=1); therefore, since the value of p is 0.2, and the value of q is 0.8.
According to the Hardy-Weinberg equation, the expected frequencies of the genotypes would add up to 1.
= p2+2pq+q2
= 1
or
= 0.22+2(0.2)(0.8)+0.82
= 1
or
= 0.04+0.32+0.64

seen before. Which of the following would help you classify the organism as a prokaryote or a
eukaryote?
a. Presence of a cell membrane
b. Presence of ribosomes
C. Presence of cilia or flagella
d. Presence of membrane-bound organelles
Answer:
d. Presence of membrane-bound organelles
Explanation:
Living organisms has been classified into prokaryotic or eukaryotic depending on the content of their cell. The basis of classification into prokaryote or eukaryote is the possession or not of a membrane-bound nucleus or organelle.
According to this question where a one-celled organism was seen in a miscrosope, PRESENCE OF MEMBRANE-MEMBRANE-BOUND ORGANELLES is the characteristics that will help in the classification of the organism as a PROKARYOTE OR EUKARYOTE.
Presence of membrane-bound organelles would help classify the organism
as a prokaryote or eukaryote.
Prokaryotes are defined as organism which don't have a true nucleus as a
result of the absence of the nuclear membrane. Eukaryotes on the other
hand have a true nucleus as a result of the presence of the nuclear
membrane.
When viewing a one-celled organism with a microscope, we are able to
classify the organism based on the presence or absence of a membrane-
bound organelle.

Compare and contrast the random sampling and mark and recapture methods of
estimating population sizes. Describe a situation in which each method would
work best and why. Justify your answer.
Explanation:
jennjjj+ii8iiiiiiiuiiiiiiiu
Random sampling and mark and recapture methods are both commonly used to estimate population sizes, but they have different strengths and weaknesses.
What is random sampling?Random sampling involves selecting a random sample of individuals from a population and using that sample to make inferences about the population as a whole. This method is typically used when the population is large and diverse, and it is difficult to observe or count all individuals. Random sampling is also useful when the population is not easily marked or tagged, as it does not rely on the use of markers.
On the other hand, mark and recapture methods involve marking a subset of individuals in a population, then releasing them back into the population and later re-capturing them. The number of marked individuals that are recaptured is used to estimate the population size. This method is typically used when the population is small, and it is relatively easy to observe or count all individuals. Mark and recapture methods are also useful when the population is easily marked or tagged, such as with fish or birds.
A situation in which random sampling would work best is a study of the population of deer in a large forest. The forest is too vast to observe or count all individuals, so a random sample of deer would be selected and observed to estimate the population size.
On the other hand, a situation in which mark and recapture methods would work best is a study of the population of fish in a small lake.
