Force applied?
Answer:
3.5m
Explanation:
Given parameters:
Force applied = 8.2N
Work done = 28.7J
Unknown:
Distance through which the force was applied = ?
Solution:
Work done is the force applied on body to move it through a particular distance.
Work done = Force x distance
Now insert the parameters and solve;
28.7 = 8.2 x distance
distance = 3.5m
Why does diuron cause coral to bleach
Simple answer:
When corals are stressed by changes in conditions such as temperature, light, or nutrients, they expel the symbiotic algae living in their tissues, causing them to turn completely white. Warmer water temperatures can result in coral bleaching. ... This is called coral bleaching. When a coral bleaches, it is not dead.
More in depth explanation:
Exposure to higher (100 and 1000 µg l-1) diuron concentrations for 96 h caused a reduction in ΔF/Fm¹, the ratio variable to maximal fluorescence (Fv/Fm), a significant loss of symbiotic dinoflagellates and pronounced tissue retraction, causing the corals to pale or bleach.

What kind of remote viewing device shows weather observers movements of fronts across large geographic areas?
Answer:
weather satellites
Explanation:
The weather satellites show which directions weather fronts are moving, what they look like from space and how much water content is in the atmosphere.
Weather satellites show where weather fronts are moving, what they look like from space, and how much water is in the atmosphere.
What are weather satellites?A weather satellite, also known as a meteorological satellite, is a type of Earth monitoring satellite that is predominantly used to monitor the Earth's weather and climate.
Satellites can be polar orbiting (covering the entire Earth asynchronously) or geostationary (covering the entire Earth synchronously) (hovering over the same spot on the equator).
Heat energy in the infrared spectrum is detected by the weather satellite (infrared energy is invisible to human eye). The satellite image displays objects based on their temperature (whether they are clouds, water, or land surfaces).
Observing the Earth from space with environmental satellites is one of the most important tools for forecasting weather, analyzing climate, and monitoring hazards around the world.

Question 1
Explain why your model demonstrates how crossing over is important to genetic variation in a species.
Question 2
Look at the offspring you created in your model. Have any of the offspring inherited a more beneficial genetic combination than the others? How could this affect their survival? Explain your reasoning.
Question 3
Why is it impossible to predict the phenotype of the offspring by observing only the phenotype of the two parents?
Answer:
the last one is:
In the process of meiosis, alleles separate and are added to the gametes in an independent manner. While each gamete (egg or sperm cell) therefore contains one allele for each gene, it's impossible to know which allele, because alleles segregate in a random manner. However, it's possible to calculate probabilities that the offspring will have a given allele using Punnett squares.
Explanation:
Crossing over process results in new combinations of alleles in the gametes (egg or sperm) formed, which ensures genomic variation in any offspring produced.
What do you mean by crossing over process?Chromosomal crossover, or crossing over, is the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids that results in recombinant chromosomes.
This process, also known as crossing over, creates gametes that contain new combinations of genes, which helps maximize the genetic diversity of any offspring that result from the eventual union of two gametes during sexual reproduction.
Crossing over is an enzyme-mediated process, where the exchange of genetic material between non-sister chromatids of homologous chromosomes takes place.

Hydrogen peroxide naturally breaks down into oxygen and water over time. When exposed to the enzyme catalase, hydrogen peroxide is rapidly converted into oxygen and water.
What feature of catalase most likely is responsible for the change in the rate of conversion of hydrogen peroxide into water and oxygen?
A, Catalase speeds up the conversion of hydrogen peroxide into water and oxygen by decreasing the reaction's activation energy.
B, Catalase bonds permanently with the reactants causing hydrogen peroxide to rapidly break down by increasing the activation energy.
C ,Catalase has a flexible structure that allows it to bind and convert any small hydrogen containing compound into water and oxygen.
D, Catalase remains intact, so small amounts of it convert large amounts of hydrogen peroxide into water and oxygen immediately.
Answer:
Catalase is an enzyme in the liver that breaks down harmful hydrogen peroxide into oxygen and water. When this reaction occurs, oxygen gas bubbles escape and create foam. Completely disinfect any surface that the raw liver touches during this activit.
Explanation:
hope this helps you a little have a great day sir/mam
Catalase speeds up the conversion of hydrogen peroxide into water and oxygen by decreasing the reaction's activation energy. Thus option A is correct.
What is the function of catalase ?Catalase is a common enzyme present in all living organisms.
These are tetramer molecule consisting of four polypeptide chains, each of these chains are over 500 amino acids.
In mammal it is found in liver and contains four iron-containing heme groups that allow the enzyme to react with hydrogen peroxide.
In mammalian cell, Catalase involve in decomposition of most toxic substance called hydrogen peroxide into less toxic products like water and oxygen.
It protect the cell from oxidative damage by reactive oxygen species.
The optimum pH and optimum temperature for the activity of this enzyme ranges from four and eleven depending on the species.

Carbon, nitrogen, and phosphorus are examples of nutrients that organisms need to stay alive. Nitrogen can be the Choose... in an ecosystem when its available forms are in short supply.
Answer:
Nitrogen is present in the soil in the form of ammonium and nitrates.
Explanation:
Nitrogen present in large amount in the atmosphere about 78 % by volumes but in an ecosystem such as land and water its available forms are in short supply because very less amount of nitrogen is produced due to the process of decomposition and some quantity of nitrogen comes from the atmosphere with the rainfall and mixes with soil and present in the soil in the form of ammonium and nitrates.
Radish color is controlled by a gene that exhibits incomplete dominance; purebred red radishes (RR) crossed with purebred white radishes (WW) make purple radishes (RW). What are the chances of producing purple offspring when you cross two purple parents?
Answer:
1/2
Explanation:
This question involves a single Gene coding for fruit color in radish plants. The gene exhibits incomplete dominance where the allele for red radish (R) and the allele for white radish (W) forms a hybrid with a purple radish (RW).
If a purebred red radish (RR) is crossed with purebred white radishes (WW), purple radishes (RW) will be formed. However, when the purple radishes are self-crossed i.e. RW × RW, the following gametes will be produced- R and W.
Using these gametes in a punnet square (see attached image), the following offsprings will be produced in the following proportions:
RR - red = 1/4
RW - purple = 2/4 or 1/2
WW - white = 1/4
Hence, the chances of producing purple offspring when you cross two purple parents is 1/2.
