The researcher chose to use the quadrat method rather than mark and recapture to sample the coral population because corals are sessile, which means they are immobile. For a sample that exhibits mobility, the mark recapture approach is employed. i.e., being movable.
Quadrat Method- In ecology, geography, and biology, a quadrat is a frame that is typically square and is used to isolate the standard unit of space for the study of an item's distribution over a vast region.
Mark Recapture Technique- When it is impracticable to count every person in a population, the Mark-Recapture approach is employed to estimate its size.

what do hippopotamus eat
Grass
Explanation:
Hippos have a healthy and mostly herbivorous appetite. Adults eat about 80 lbs. (35 kg) of grass each night, traveling up to 6 miles (10 km) in a night to get their fill. They also eat fruit that they find during their nightly scavenging, according to National Geographic.
Suppose
if we have more than 50% recombinant frequency in any case, then what
would be the best interpretation of that case?
A. Gene are present on same chromosomes
B. Genes are linked
C. Genes are having possibility of crossing over
D. Genes are present on different homologous pair
All options are correct, expect option B.
The frequency of a single chromosomal crossover occurring between two genes during meiosis is known as the recombination frequency. The measure used to describe recombination frequencies of 1% is the centimorgan (cM).Genes that are near to one another tend to be more connected than genes that are farther apart. The frequency of recombination will decrease with increasing linkage and vice versa. Linkage thereby lowers the frequency of the hybrid.A 50% recombinant frequency indicates that the genes are present on the same chromosome but are far from one another, suggesting that more than one crossover may have occurred during each meiosis. They might not be related because they are on different chromosomes. There is independent assortment in these genes.Therefore, all the options expect B. are correct.

Under the right circumstances, the lysogenic cycle changes to the lytic cycle. Explain whether the lytic cycle can change to the
lysogenic cycle. Explain your answer in 3-5 sentences. (4 points)
The lytic cycle can change to the lysogenic cycle in the given manner discussed The lysogenic cycle allows a phage to reproduce without killing its host. Some phages can only use the lytic cycle, but the phage we are following, lambda ( λ), can switch between the two cycles.
The lytic cycle:The lytic cycle infects a bacterium, captures the bacterium to make lots of cycles , and then kills the cell by making it explode (lyse).
The lysogenic cycle:The cycle infects a bacterium and inserts its DNA into the bacterial chromosome, permitting the cycle DNA (now called a pro phage) to be copied and passed on with the cell's own DNA.
Can lytic become lysogenic?During lysogeny, the pro phage will consist in the host chromosome until induction, which in the causes excision of the viral genome from the host chromosome. After induction has resulted the temperate phage could proceed through a lytic cycle and then undergoes lysogeny in a newly infected cell.
How lytic cycle is different then lysogenic cycle?The important difference between lytic cycle and lysogenic cycle is that lytic cycle destroys the host cell on contrary lysogenic cycle doesn't destroys the host cell. Where as Viral DNA destroys the host cell DNA and arrests cell functions in the lytic cycle.

Decreased by the breakdown of organic waste
(A) Acidity
(B) Turbidity
(C) Hardness
(D) Dissolved oxygen
The breakdown of organic waste can lead to a decrease in the level of dissolved oxygen in water bodies. The correct option is (D) Dissolved oxygen.
When organic matter, such as dead plants or animal waste, decomposes in water, bacteria and other microorganisms consume the oxygen dissolved in the water as they break down the organic material. This process is known as biochemical oxygen demand (BOD).
As the organic waste breaks down and consumes the available oxygen, the dissolved oxygen levels in the water decrease. This reduction in dissolved oxygen can have negative effects on aquatic ecosystems and the organisms that rely on oxygen for their survival, such as fish and other aquatic animals.
In extreme cases, a decrease in dissolved oxygen can lead to hypoxia, which is a state of low oxygen levels that can result in the death of aquatic organisms.
Therefore, the breakdown of organic waste is associated with a decrease in dissolved oxygen.

During this phase, reactions require oxygen?
All three phases of respiration are used in the breakdown of carbohydrates (glycolysis, citric acid cycle, and the electron transport chain).
No oxygen is needed for glycolysis. All cells, including anaerobic cells that are killed by oxygen, engage in this anaerobic kind of respiration. When there is insufficient oxygen, your muscle cells additionally add a fermentation phase to the glycolysis process. Pyruvate is changed into lactate by them.
Aerobic refers to cellular respiration processes that need oxygen.
The only metabolic process indicated that specifically requires molecule oxygen is the electron transport mechanism. One of the most electronegative elements in human bodies, oxygen serves as the final electron acceptor in the electron transport chain.

Although the total distance the impulse travels in the reflex arc is less than 3 meters. the time taken is more than 0.04 seconds and the time taken is more than expected because of Synapses or due to gaps between neurons.
Diagram displays the whole reflex arcs from the tip of the finger to the spinal cord and then back out to a closer muscle, possibly in the forearm or the arm. Because the signal doesn't have to go all the way back to the finger, the total distance is less than 3 meters. Considering that it just travels back a portion of the way, less than 3 meters, it takes. Let's see, it takes more than twice as long, therefore the query makes us think about why the delay. Where is the hold-up what is happening there, and the key to this is that the gray matter of the spinal cord doesn't truly contain mylin, despite the fact that we said it- accelerates electrical conduction through the axon in the nerves of the extremities. Mylin has a whitish color, which contributes to the white matter's appearance of whitishness. Thus, the electrical signal becomes slower.

all chemical processes which take place in living cells ??
Biochemical reactions are chemical processes that occur within living organisms.
Chemical processes known as "biochemical reactions" happen within the cells of living beings. The study of biochemistry shows that understanding both chemistry and biology is necessary to comprehend how cells function in living things at the level of the organism. Metabolism is the collective term for all biological processes that occur within an organism. Both exothermic and endothermic reactions are a part of it.
Catabolic reactions are exothermic processes that occur within living things. These processes disassemble molecules into smaller parts while also releasing energy. The breakdown of glucose is an illustration of a catabolic reaction, which releases the energy required by cells for their vital functions. Anabolic reactions are endothermic processes that occur within living things. These processes combine tiny molecules into larger ones.
A biochemical reaction is the transformation of 1 molecule to a one-of-a-kind molecule inside a mobile. Biochemical reactions are mediated through enzymes, which might be biological catalysts which could alter the rate and specificity of chemical reactions internal cells.
Photosynthesis, gluconeogenesis (synthesis of glucose from non-carbohydrate resources, specifically used by the brain), protein biosynthesis, fatty acid synthesis, glycolysis, Krebs cycle, urea cycle, glycogenolysis are some common examples of biochemical reactions.

While heating two different samples of water at sea level, one boils at 102°C and one boils at 99.2°C. Calculate the percent error for each sample from the theoretical 100.0°C.
The percent errors are 0.8 percent and 2 percent
It is given that the theoretical boiling point of water is 100.0 degree celsius
When any impurity is added to water, its boiling and freezing points increase or decrease accordingly.
We are required to find the percentage error in calculation of freezing point or in simple words deviation from theoretical value of 100 degrees
We are given two temperatures
Case 1:
When the boiling point is 99.2 degree
deviation from theoretical value= 100-99.2 = 0.8 degrees
Percent error in calculation from theoretical value =deviation/original value x 100
= 0.8 /100 x 100 = 0.8 per cent
Case 2:
When the boiling point is 102 degree
deviation from theoretical value= 102-100 = 2 degrees
Percent error in calculation from theoretical value =deviation/original value x 100
= 2/100 x 100 = 2 per cent
Hence the percent errors are 0.8 percent and 2 percent

lonic bonds form between ionized atoms.
Ionic bonds, also known as electrovalent bonds, are a type of linkage created in a chemical molecule by the electrostatic attraction of ions with opposing charges. When the valence (outermost) electrons of one atom are permanently transferred to another atom, a bond of this kind is created. If an atom gains electrons, it becomes a negatively charged ion (cation), while if it loses them, it becomes a positively charged ion (cation) (anion). Following is a quick discussion on ionic bonds. Ionic or electrovalent compounds are produced via ionic bonding, and the compounds generated between nonmetals and alkali and alkaline-earth metals serve as the best examples of this type of compound.
