how will photosynthesis affect oxygen levels?
(also if anyone could help me with the rest of these answers, that would be great <3)
The process of photosynthesis positively affects the level of oxygen in the ecosystem. This is because oxygen is the byproduct of the photosynthesis mechanism along with the main product known as Glucose.
What is Photosynthesis?Photosynthesis may be defined as a process through which green plants and some photosynthetic algae synthesize their own food in the form of glucose with the help of carbon dioxide and water in the presence of sunlight.
The complete reaction of photosynthesis si as follows:
[tex]6CO_2+12H_2O[/tex] → [tex]C_6H_1_2O_6+6O_2+6H_2O.[/tex]With the help of this reaction, this is determined that if the rate of photosynthesis increases, the level of oxygen is positively affected which means it is also increasing. It is opposite to the process of cellular respiration which involves oxygen as a reactant.
Therefore, the process of photosynthesis positively affects the level of oxygen in the ecosystem.

What is herd immunity, and why are vaccines important for achieving herd immunity?
Answer:
Herd immunity is a form of indirect protection from infectious disease that can occur with some diseases when a sufficient percentage of a population has become immune to an infection, whether through vaccination or previous infections, thereby reducing the likelihood of infection for individuals who lack immunity.
Explanation:
Vaccines create immunity without causing illness or resulting complications. Herd immunity makes it possible to protect the population from a disease, including those who can't be vaccinated, such as newborns or those who have compromised immune systems.

The internal transport of water and minerals in plants requires that two systems work
together. Which diagram correctly describes how the two systems accomplish this?
Answer: it’s F
Explanation:
Got it correct
The correct answer is diagram F in the image given along with the question as it shows correctly describes how the two systems accomplish the internal transport of water and minerals in plants requires that two systems work.
It has 2 steps:
Absorption through the root system. Transport by shoot system and stomata in leaf tissues.What is the internal transport of water?Transport in biology method sporting substance absorbed or made withinside the frame of an organism to all different components of its frame.
In flora, it's miles most effective water and minerals that want to be transported to its different components. Another component that desires to be transported to different components of the flora is the meals organized in leaves.
This is due to the fact a plant has a branching form so it receives carbon dioxide for photosynthesis and oxygen for respiratory from the air at once through diffusion.
Hence concluded that the F option in the image is the correct answer.

Which of the following energy transformations occur when humans use energy from food to exercise?
A. Mechanical - thermal - chemical
B. Thermal - electrical - mechanical C.Radiant - mechanical - thermal
D. Chemical - mechanical - thermal
Answer:
D. Chemical - mechanical - thermal
Explanation:
Food contains chemical energy; when our bodies break down and digest food, the bonds that are broken apart release chemical energy. Our bodies convert this to mechanical energy to power movement, from movements as small as blinking or our hearts beating, to bigger movements like running or swimming. When we exercise or move, we also release heat which is thermal energy.
The energy transformations that occur when humans use energy from food to exercise is: D. Chemical - mechanical - thermal.
What is energy?Energy can be defined as the ability to do work. Thus, energy must be possessed or transferred to a physical object (body) before it can be used in doing a work or heating a system.

sugar in the urine
water in the urine
water in the blood
The symptoms that a doctor says indicate that there is a problem with one's body are that the sugar in urine, which is in the second option, is not normal because the sugar returns to the blood during the filtration.
What is the significance of the urine abnormality?High levels of sugar in the urine indicate uncontrolled diabetes and metabolic disorders like the Fanconi syndrome, where the body is unable to reabsorb sugar from the urine. This can lead to high levels of sugar in the blood, which can damage blood vessels and lead to serious health complications.

VNTRs are highly conserved in human populations. d. PCR amplification generates large numbers of linear DNA fragments. e. RNA molecules can be used as hybridization probes in Southern blot analysis. Separate your answer(s) with a comma, and enter only the letter(s) of your choice(s
Answer:
b. Antibodies are used for Northern blot analysis.
c. VNTRs are highly conserved in human populations.
Explanation:
The northern blot technique is used in molecular biology laboratories for detecting specific RNA molecules in a sample of RNA derived from a particular cell/tissue. Antibodies can be detected by the enzyme-linked immunosorbent assay (ELISA). In ELISA, antigens are used to detect specific antibodies: the addition of the antigen produces a positive reaction i.e., formation of the antigen-antibody binding complex. Subsequently, a second antibody with a particular marker is added to bind with the complex, thereby producing a change in the color and thus evidencing the presence of the target antibody in the sample. On the other hand, the variable number of tandem repeats (VNTR) are short sequences (around 20 to 100 bp) whose number of repetitions varies at specific loci in the genome of many organisms, including humans. Since VNTR sequences exhibit variation in length between individuals of the same species/population, they are widely used as molecular markers to identify individuals, QTL (quantitative trait loci) mapping, establish phylogenetic relationships among individuals/cultivars/lines, etc.
