Justify your choice by writing a hypothesis to explain how it has stopped the algae from making ATP, NADPH and sugars. You will be able to revise your hypothesis as you do more experiments

Explanation:

The hypothesis will be

High sea temperature inhibit Algae growth

Herbicides reduces algae photosynthesis rate

Algae respond to temperature differently some thrive at a low temperature, some at a moderate temperature but when the temperature is very high the rate of photosynthesis will reduce because they can not undergo the normal body physiological function as a result of harsh environment. In green plant at a very high temperature stomata closes to regulate water loss this prevent Carbon dioxide from coming in and photosynthesis rate reduces

Paraquat and Diuron are herbicide that prevent the growth of plants, when they are sprayed Algae is affected they die from immediate action of this chemical and their colour changes since chloroplast the green pigment is where light hit for photosynthesis to occur when the color changes the active site is affected photosynthesis can no longer occur.

Answer:

Diuron

Explanation:

Increasing the temperature only decreases the sugar, not the ATP and NADPH. I predict that Diuron will be inhibiting photosynthesis because photosynthesis as a whole should not work if Photosystem II is interfered with. Also, because Paraquat only lowers NADPH and sugar and not ATP, Diuron is the only choice left.

Answer:

Diffusion is one principle method of movement of substances within cells, as well as the method for essential small molecules to cross the cell membrane. Gas exchange in gills and lungs operates by this process. Carbon dioxide is produced by all cells as a result of cellular metabolic processes.

Explanation:

The diffusion of a substance into or out of a cell requires a process called diffusion, by which the molecules pass out through the plasma membrane.

Diffusion is a key mechanism for material transfer within cells and for the passage of critical tiny molecules across the cell membrane. This process controls the exchange of gases in the gills and lungs. All cells release carbon dioxide as a byproduct of biological metabolism.

There are two processes by which the molecules pass through a semi-permeable membrane. The processes are osmosis and diffusion. When the material transfer from low concentration to higher concentration.

Thus, diffusion is the process by which molecules travel through the plasma membrane to allow material to enter or exit a cell.

Explanation:

Answer:

Creatine kinase (CK) has several functions in cellular energy metabolism. It catalyzes the reversible transfer of high-energy phosphate from ATP to creatine, facilitating storage of energy in the form of phosphocreatine.

The evidence suggests that the myofibrils' creatine kinase is sufficient to maintain typical tension and relaxation, typical Ca sensitivity, and typical kinetic properties.

On the long axis of the myocytes, groups of myofibrils—long contractile fibers run parallel to one another (long single multinucleated cells that combine to form the muscle).

On the cell's long axis, the myocytes are situated next to one another in parallel.

Creatine, a molecule found in your muscle cells that aids in the production of energy by your muscles, needs a phosphate group added to it by CK.

Creatine becomes the high-energy molecule, phosphocreatine, which your body uses to produce energy, when CK attaches phosphates to it.

According to the research, the myofibrils' creatine kinase is enough to keep their regular kinetic features, like tension and relaxation and Ca sensitivity, in place.

Thus, this is the role of creatine kinase in the myofibril.

Answer:Anaerobic respiration is respiration using electron acceptors other than molecular oxygen. Although oxygen is not the final electron acceptor, the process still uses a respiratory electron transport chain.

Explanation:hope this helps

Answer and explanation:

Phenylalanine is an amino acid that is very important for our bodies to function correctly but it isn't synthesized in our cells, so the only way to incorporate it is by having it in our diets, this is why phenylalanine is an essential amino acid.

Phenylalanine can be found in milk, eggs, chicken, and liver, among other foods known to be good protein sources. Given the fact that phenylalanine is an essential amino acid, the amount we ingest of it in our diet will directly impact on the availability of this amino acid in our body.

Phenylalanine is an amino acid and, as such, it will enter the metabolic pathway of protein catabolism, where it will be degraded to be fully usable for the body. Phenylalanine will be metabolized into acetoacetic acid and fumaric acid, and is the precursor of catecholamines such as epinephrine and norepinephrine, while also being part of the structure of several neuropeptides.

Depends on what is freezing. Generally it increases density.

Explanation:

water when frozen has a lower density. but generally freezing increases density because it packs the molecules tighter

Answer:

Millions of years from now, paleontologists may dig into Earth and uncover fossils from our own time. They may, like scientists today, construct a chronology of what came before them, watching past species popping into—and later out of—existence. Today, humans are continually driving species to extinction—by one estimate, almost 500 vertebrate species have gone extinct in the past 100 years—but will those future scientists be able to tell? New research suggests that it might not be easy: Only a small proportion of these human-caused extinctions will leave behind a fossil trace—and the most threatened species are the ones least likely to be preserved for posterity.

The history of life on Earth is punctuated by what researchers call the “Big Five” mass extinctions, a group that includes the dinosaur-killing Cretaceous-Tertiary extinction and several other, even more severe, events. Many scientists now want to add a sixth: the one that humans are causing all over the globe today. But it’s hard to gauge just how severe the current extinction crisis is, compared with others in Earth’s sometimes tumultuous history. Modern extinctions are documented, sometimes in real time. But the Big Five are measured using only the fossil record, a history of those species that were buried and preserved by sediments over time.

That’s why Roy Plotnick, a paleontologist at the University of Illinois, Chicago, and lead author of the study, thinks about far-flung scenarios involving future paleontologists. “We really need to look at modern day extinctions as if they were in the fossil record already, in order to make a comparison,” he says. So he and his colleagues searched fossil databases for modern mammal species—both those threatened by extinction and those that aren’t—to see how many modern extinctions would be detectable by relying only on fossils.

Answer:

The complementary DNA strand, according to the nucleotide sequence of the other strand is 3' - A C A T C G A C G C G C A - 5'

Explanation:

Each strand of DNA is made up of specific sequences of the four nucleotides present in this molecule, adenine, thymine, cytosine and guanine.

In double-stranded DNA, one strand complements the other —according to the complementarity of nitrogenous bases— where a purine, adenine and guanine, are joined with a pyrimidine, thymine and cytosine, respectively:

According to this, the complementarity of the strands is:

    5' - T G T A G C T G C G C G T - 3'

    3' - A C A T C G A C G C G C A - 5'

The DNA strands remain linked by hydrogen bonds between their nitrogenous bases, until such time as they must be separated for transcription.

Answer:

B is the correct answer.

A is incorrect because respiration is always occuring in animals and plants, therefore it means it does not require the presence of light. Photosynthesis does produce ATP, though.

Not C because photosynthesis does not occur in animals

Not D because they both are  different processes. They don't really depend on each other, though they could occur at the same time.
