Explanation:
Let the green-melon parents be Gg, then we expect the cross with the yellow-melon plant gg so as to produce 50% Gg and other 50% of gg offspring. What we observed was that 53 green and a 41 yellow. Based on the total number of 94 offspring , we expected half and a half ratios to be 47 of each color.
Observed(o) Expected(e) (o-e) [tex]$(o-e)^2$[/tex] [tex]$(o-e)^2/e$[/tex]
Green-melon plant 53 47 6 36 0.766
Yellow-melon plant 41 47 -6 36 0.766
Therefore the chi-square value is 1.53 which is less than the critical value of 3.84. Therefore, the null hypothesis is accepted.

Q29. How has the Sun caused changes in global and hemispheric temperatures over
the past thousand years?
Answer:
the global average surface temperature has increased over the 20th century by about 0.6 degrees C
In the last thousand years, solar activities have caused a decrease in temperature in the northern hemisphere.
We can arrive at this answer because:
The changes in the sun were very important for the rise in temperatures during the 1000's to the 1100's.However, over the years this activity and changes in solar production caused this temperature to drop, especially in the northern hemisphere.Even though this decrease in temperature was something small and subtle, in the last thousand years it has been established in the region above the equator.This process explains how global warming was not the result of changes in solar production, as this change caused a cooling. In this case, this confirms that global warming was caused by the accumulation of greenhouse gases caused by human actions.

The light-independent reactions of photosynthesis, also known as the Calvin cycle, must repeat three times in order for a cell to have enough material to construct half a glucose molecule. A variety of molecules are used and produced during this process. Identify the molecules into three categories: molecules brought in and used in three turns of the Calvin cycle, molecules produced during three turns of the Calvin cycle that leave the cycle, and molecules used and regenerated within the Calvin cycle during three turns.
Answer:
- molecules brought in and used in three turns of the Calvin cycle = carbon dioxide (CO2)
- molecules produced during three turns of the Calvin cycle that leave the cycle = Glyceraldehyde-3-phosphate (G3P)
- molecules used and regenerated within the Calvin cycle during three turns = Ribulose bi phosphate (RUBP)
Explanation:
The second stage of photosynthesis, called CALVIN CYCLE, occurs in the stroma of the chloroplast. The processes that occur in this stage can be divided into three stages namely: carbon fixation, reduction and regeneration.
As rightly stated in this question, the calvin cycle must repeat three times in order for a cell to have enough material to construct half a glucose molecule. Hence;
- In carbon fixation, molecules of carbon dioxide (CO2) are brought in and used in three turns of the Calvin cycle. The CO2 combines with a CO2 acceptor called RUBP (ribulosebiphosphate) to produce PGA (3-phosphoglycerate).
- In the reduction stage, PGA is reduced to Glyceraldehyde-3-phosphate (G3P). This G3P molecule is produced during three turns of the Calvin cycle and leaves the cycle to be used to form glucose.
- In the regeneration stage, remaining molecules of G3P are used to regenerate RUBP in order for the cycle to continue. Hence, RUBP molecules are used and regenerated within the Calvin cycle during three turns.

Answer:
Explanation:an excess of water in the body can lead to a low concentration of sodium in the blood Hyponatremia is a low concentration of sodium in the blood because of excessive retention of water
Answer: Extensive drinking of water during exercise leads to a condition called hyponatremia.
Explanation: In this, water causes dilution of the blood, and sodium levels drop too low. To maintain homeostasis in such a situation, water intake should be reduced, sodium-containing fluids should be taken, extra salt may also be added to the food

Having investigated the impacts of the European Green Crab on the intertidal zone community, the Department of Fish and Wildlife is considering using parasitic barnacles (Sacculina) to control the crab. Given what you know about the importance of species interactions to community structure, what would you suggest should be learned about this parasitic barnacle species before it is introduced into the intertidal community you have been studying
Answer:
Method of controlling the population of crabs.
Explanation:
The method of controlling the crabs by parasitic barnacle species I suggest should be learn before its introduction because this method provides valuable knowledge about the method the parasitic barnacle species control the crabs population. This barnacle species is a parasite that feeds on the crabs, it controls the population of crab by not killing the crabs but attack on the reproductive part of the crabs that leads to infertility and as a result the population of the crabs are decreases and controlled.

Why is the 3-dimensional shape of a macromolecule (ex: protein) important to know from the perspective of understanding
the molecular basis of human disease? 2 pts
A/ Mutations in genes that cause a change in amino acid primary sequence can cause a change in the protein's function in a
cell. For example, it can cause the protein to mislocalize; the protein is now recruited to a specific site in the cell, like the
nucleus, where it can cause cellular dysfunction.
B/ If the protein is an enzyme, the 3-dimensional shape of the active site can be altered and decrease the rate of a reaction that
is catalyzed by that enzyme.
C/ If the protein is an enzyme, the 3-dimensional shape of the active site can be altered and increase the rate of a reaction that
is catalyzed by that enzyme.
D/ Only options A and B may be true.
F/Antions A, B and C may be true.
Answer:
A, B and C may be true
Explanation:
The three-dimensional structure (3D) of a protein, also known as tertiary structure, is critical to its function. In general, the 3D protein structure consists of alpha-helix and beta-sheets (secondary structures) associated through disordered coiled-coil regions. Genetic mutations may cause modifications in the 3D protein structure by modifying amino acids that are added to the growing polypeptide chain during the process of translation. In consequence, the relationships among amino acids (i.e., the intermolecular attractive forces that hold them together) may also be altered by these mutations. In general, mutations that generate amino acid changes at the active site of the enzyme will have a deleterious effect, thereby decreasing or inactivating protein function. However, there are situations where a mutation may be beneficial and can eventually increase the rate of reaction of a protein.

In snarlymonsters, the number of teeth is polygenic. The recessive condition (aabbcc) results in a toothless snarlymonster, and the dominant condition (AABBCC) results in a snarlymonster with 6 teeth. There are 5 other possible variations. How many teeth would a AaBbCc snarlymonster have
Answer:
The correct answer is - 3 teeth.
Explanation:
It is given that in Snarlymonsters the number of teeth is a polygenic trait and recessive conditions do not form the teeth in the Snarlymonsters which means only dominant alleles are responsible for the teeth.
So, aabbcc = no teeth
AABBCC = 6 teeth
so the number of teeth is the number of dominant alleles present in the SNarlymonster like A, B, C present in offspring.
In the case of the AaBbCc genotype, there are 3 dominant genes A, B, and C, so 3 teeth are present in snarly monsters.
what is the difference between a freshwater ecosystem and a aquatic ecosystem?
Answer:
Explanation:
An aquatic ecosystem is an ecosystem in a body of water. Communities of organisms that are dependent on each other and on their environment live in aquatic ecosystems. The two main types of aquatic ecosystems are marine ecosystems and freshwater ecosystems.Freshwater ecosystems are a subset of Earth's aquatic ecosystems. They include lakes, ponds, rivers, streams, springs, bogs, and wetlands. They can be contrasted with marine ecosystems, which have a larger salt content
freshwater and marine life is the habitat they come from in the wild. Freshwater fish live in streams, rivers and lakes that have salinity of less than 0.05 percent. ... A marine animal's habitats include coral reef and seagrass bed.
Explain the three principles of the cell theory
Answer:
The three tenets to the cell theory are as described below: All living organisms are composed of one or more cells. The cell is the basic unit of structure and organization in organisms. Cells arise from pre-existing cells.
Explanation:
Can I have brainliest?
Answer:
Answer: 1) All the living organims are compound by one or more cells . 2) The cell is the structural and functional basic unit of life. 3) All cells are originated from other cells.
Explanation: Cell theory describes the characteristics of living organisms and was proposed and refined by many scientists like Schwann and Schleiden. The first principle describes the constitution of living organisms, all of them, unicellular or multicellular are compund by cells. The second principle says that cell is the unit of life in fuctions as metabolism and structural as in tissues. The third principle says that cells can only be generated by division of preexisting cells.

3. What would happen if they crossed yellow jellyfish with coober Complete
the Pummert squire to help you determine the probability for each color of
Sive the possible genotypes and phenotypes for the offspring
What percentage of the offspring would be yellow?
What percentage would be blue
What percenge would be onders green
Answer:
We know that the color of jellyfish is controlled by codominance inheritance pattern and yellow Y and blue B are two alleles and in case of heterozygous the goober or green color occurs then,
If Yellow jellyfish is crossed with goober, that is, YY X YB.
the punnett square will be -
Y Y
Y YY YY
B YB YB
The possible genotype of offspring will be YY, and YB and therefore, the possible phenotype of offspring will be Yellow, and Green. The Percentage of yellow offspring will be 50% as two out of four are dominant for Y allele and two heterozygous conditions that is 50 % and as there are two copies B alleles are not present so zero percent of blue color.
