Answer:
it is also transfer in chemical energy
Photosynthesis is a biological process that illustrates the general principles of energy conservation and transformation.
What is photosynthesis?Photosynthesis is the process by which plants convert sunlight, water, and carbon dioxide into oxygen and sugar energy.
The photosynthesis process is divided into two stages: light-dependent reactions and light-independent reactions.
The ATP and NADPH produced in the light-dependent reactions (also known as the Calvin cycle) are used to fix carbon dioxide and synthesise glucose in the light-independent reactions.
A series of enzyme-catalyzed reactions convert carbon dioxide into glucose in this process.
Energy is neither created nor destroyed during the photosynthesis process. Energy is instead transformed from one form to another. Light energy, for example, is converted into chemical energy in the form of ATP and NADPH.
Not all of the energy input is converted into chemical energy. Heat energy accounts for a portion of the energy lost.
This is because energy transformations are never completely efficient, and some energy is always lost as heat.
Thus, photosynthesis exemplifies the general principles of energy conservation and transformation by showing how sunlight energy is converted into chemical energy in the form of glucose.

Answers
A study showed that morbidity of children with anemia was 7:1000. This means that (B) 7 children out of 1000 had anemia or suffered from anemia.
The study showed that morbidity of children with anemia was 7:1000. The term "morbidity" refers to the incidence of a disease or the prevalence of a condition. The ratio 7:1000 indicates that for every 1000 children, 7 of them had anemia or suffered from anemia. This means that 0.7% of the children in the study had anemia.
However, it does not mean that 7 children out of 1000 died of anemia or that they recovered from blood-borne pathogens. It simply means that 7 out of 1000 children had anemia. Morbidity is often used in public health to determine the incidence of a disease and to track its prevalence over time. It is a useful indicator of the health of a population, as it can help public health officials to identify trends and develop strategies to prevent and treat diseases.
In conclusion, the study showed that 7 children out of 1000 had anemia or suffered from anemia. The correct answer is B.

Check all that are true of the following scenario.
An archer strings an arrow on a bow and draws the string back. Aiming the bow
upwards at a 45 degree angle, the archer pauses with arms locked into position and
then releases the string. The arrow flies upwards making an arc and then sticks into
the trunk of a tree with an audible thud.
At least four different types of energy are illustrated in this example.
The first energy transformation in the scenario is chemical energy to kinetic.
From the time the archer draws the bow until the thud us heard, entropy increases in
the universe.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the
muscles of the archer.
When the arrow sticks into the tree the original energy has all been used up.
Answers
Statements 1 and 3 are true, while statements 2 and 4 are false.The first energy transformation in the scenario is chemical energy to kinetic. - True.
The archer converts chemical energy stored in their muscles into kinetic energy when they release the string and propel the arrow forward.From the time the archer draws the bow until the thud is heard, entropy increases in the universe. - False. Entropy is a measure of disorder or randomness in a system. In this scenario, the archer's actions do not necessarily lead to an increase in entropy.
The energy of the arrow at the end of the scenario is equal to the energy exerted by the muscles of the archer. - False. Energy is conserved in a closed system, but some energy is lost as heat and sound during the process. Therefore, the energy of the arrow at the end may be less than the energy exerted by the archer's muscles.
When the arrow sticks into the tree, the original energy has all been used up. - False. Energy is not created or destroyed but rather transformed from one form to another. Some of the initial energy from the archer's muscles is transferred to the arrow's kinetic energy, but it is not entirely used up.In summary, statements 1 and 3 are true, while statements 2 and 4 are false.

The allele for a widows peak hairline is recessive. Mulan has a widow’s peak. Both of her parents have widow’s peaks. What is the probability for Mika to have a widow’s peak. Create a Punnett Square.
Answers
The probability for Mika to have a widow’s peak is 100% or 1.0. The Punnett square is in the image attached.
How to create a Punnett square?Assuming that the genotype for the widow's peak allele is "W" and the genotype for the non-widow's peak allele is "w", we can represent the genotypes of Mulan's parents as WW and Ww, since both have widow's peaks.
To create a Punnett Square, list the possible gametes that each parent can produce along the top and left side of the square, and then fill in the boxes with the resulting genotypes of their offspring:
| W | w
--|----|---
W | WW | Ww
--|----|---
W | WW | Ww
Each box represents a possible offspring genotype. The probabilities for each genotype can be calculated by counting the number of boxes with that genotype and dividing by the total number of boxes.
In this case, there are four possible genotypes for the offspring: WW, Ww, wW, and ww. The first three genotypes all result in a widow's peak, while the fourth genotype results in a non-widow's peak.
Counting the boxes, we see that there are 2 boxes with the WW genotype, 2 boxes with the Ww genotype, and 0 boxes with the wW genotype or ww genotype. This means that the probability of Mika inheriting a widow's peak is 100%, or 1.0.

Answer: Raymond Wang: How germs travel on planes – and how we can stop them
1. After completing the unit and watching the video, explain how the unit about oceans and the video about germs on a plane relate?
In his video Raymond explains how the diseases are transmitted through planes from one country to another and the difficulties faced to prevent the spread of diseases due to the air circulation in the planes. It is always difficult to screen the person with disease and prevent them from getting into the plane since the air circulates in the conventional cabins. When a person sneezes, the air will get swirled multiple times and spread the disease.
2. Using examples from the video, explain why it is difficult to keep people who are sick off of planes.
It’s difficult to pre-screen for diseases. When someone goes on a plane, they could be sick and actually be in this latency period in which they could have the disease but not exhibit any symptoms and could possibly spread the disease to many other people.
3. How does Wang illustrate what happens in a conventional airplane cabin when someone sneezes?
He illustrates how the air is just being circulated throughout the plane. When someone sneezes, the air is just being circulated into the air. This means that everyone on that plane has breathed in that person’s sneeze because it’s such a compact place.

What is mitosis?
Mitosis is a cell division process through which a diploid somatic cell (2n), produces two identical daughter diploid cells (2n).
During mitosis, the whole-cell first suffers duplication of its content and then it separates. Mitosis occurs in somatic cells and in germ cells.
In this example, we can see
One cell with two chromosomes (step 1). This cell duplicates its content, and now each chromosome is composed of two chromatid sister (step 2). Chromosomes move to the equatorial plane where they align (step 3) and then each chromatid separates from the sister chromatid and moves foward one of the cell poles (step 4). The cell divides and the two resulting cells have two chromosomes, just as the parental cell (step 5)A) This model results in two identical daughter cells.

disadvantages of the complement fixation test
Answers
Explanation:
The complement fixation test has several disadvantages.
First, the test is time-consuming and labor-intensive. It requires multiple steps and a long incubation period, making it difficult to use for rapid diagnosis.
Second, the sensitivity of the test is relatively low compared to other tests. This means that it may miss some cases of infection.
Third, the test is prone to false positive results due to the presence of non-specific antibodies in the sample. This can lead to incorrect diagnosis.
Fourth, the test is not as specific as other tests, which means it may produce false positive results due to cross-reactivity with other antigens.
Finally, the test is expensive and requires specialized equipment and reagents. This makes it difficult to use in resource-limited settings.

B) Species can change drastically, multiple times, over very short periods of time.
C) Species can change drastically for a short period of time, and then undergo very little change over a long period of time, followed by another short period of drastic change.
D) Species can change gradually and consistently over a very long period of time.
Answers
Species change gradually and consistenly over a very long period of time. This is known as species adaptation. Thus, the correct option is D.
Species do not undergo drastic changes over a short period of time, rather it is a gradual change which occurs. These changes accumulate over a long period of time.
The changes are a result of modifications in the phenotype due to the mutations in the genotype. These mutations occur for better adaptation to the changing environment for the survival of the species.
Thus, the change that is seen in the bivalves has occurred over a long period of time gradually for adapting to the environment in a way that facilitates survival of the bivalves shown in the diagram.

In 3–5 sentences, relate the impact of the industrial use of water for hydraulic fracturing (fracking) with the availability and quality of water.
SOMEONE PLEASE HELP!
Answers
Answer:
The industrial use of water for hydraulic fracturing, or fracking, can have a significant impact on the availability and quality of water resources. Fracking requires large volumes of water to be mixed with chemicals and injected underground to extract oil and gas from shale formations. This high demand for water can strain local water supplies, especially in regions already facing water scarcity or drought conditions. Moreover, the water used in fracking becomes contaminated with various chemicals and pollutants, making it challenging to treat and potentially affecting the quality of nearby water sources through leakage or spills. The potential depletion and contamination of water resources due to fracking underscore the importance of careful management and regulation to ensure the sustainable use and protection of water supplies.
