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.

This was the only treatment options adopted for the Ebola in  1995 in the Democratic Republic of Congo. The assumption was that immune response is generated by the virus in the WBC of the infected individuals. These response produce antibodies.

A total if 8 patients were transfused with these blood contained antibodies, but one of these died, the remaining 7 patients survived.

The antibodies were believed to  have  multiplied(produced b-cells) to neutralize the Ebola virus(antigens)  and to ensure the survival of the patients

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

Answer:

The pesticide measurements were the dependent variable

Explanation:

According to this question, an experiment to determine if pesticide used at local farms was causing fish kills in a local pond was conducted by two students. They followed the following steps:

- Select one location to collect water samples in the pond.

- Collect a 5-mL water sample at 8 am for two days.

- Measure the amount of pesticide present in each sample using the same measurement tools

However, after analyzing the data, they concluded that "runoff from farms is not causing the fish to die in the pond". The students' conclusion is not reliable because THE PESTICIDE MEASUREMENTS WERE THE DEPENDENT VARIABLE.

Note that, the dependent variable in an experiment is the measured variable while the independent variable is the manipulated variable. In this case, the students ought to measure the death RATE OF FISH KILLS as the dependent variable instead. The PESTICIDE is the independent variable of the experiment not dependent variable. This was the reason for the unreliability of the conclusion.

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:

C. Net Primary productivity

Explanation:

In an the food chain of an ecosystem, energy is constantly being gained and most. Producers are the set of organisms that start the energy cycle via the process of photosynthesis. The gross primary productivity (GPP) is the amount of energy that the producer is able to capture from sunlight during photosynthesis.

The rate at which that captured energy is used to produce chemical organic compounds, which served as food, is called the primary productivity of the producer. However, the NET PRIMARY PRODUCTIVITY (NPP) is the energy available to consumers, which is determined by subtracting the energy used by plants via metabolism, from the total energy transformed by the process of photosynthesis. Hence, mathematically, NPP = GPP - R

Where, R = energy lost via respiration.

Answer:

For example, when a pot of water is placed on the stove to boil, conduction heat warms up the pot, which then heats the water molecules inside. As these molecules heat, convection causes them to move away from the interior of the pot as they are replaced by cooler molecules.

Answer:

The model could help the engineers by giving they a prototype to build off of so they have an idea of what they ship looks like, and if the test it, they could troubleshoot and see the errors/successes of the model.

Explanation:

The engineers first build several models of the ship as the model could help the engineers by providing them a prototype to build of so that they have an idea of what or how the ship will looks like, and if they test it, they could troubleshoot and see the errors or successes of the model of the ship.

Science has the factual based knowledge and it has about the Nature as well as the natural world that has created on the basis of observations and the experiments. It has the study of the experiments and observations and it has totally depend upon the scientific result that has obtained after the scientific experiments.

There are several fields in which science has been applied and these field are healthcare, telemarketing, environmental engineering, banking, government regulation, space, biochemistry, physics, chemistry, biochemistry and astronomy, engineering.

Therefore, The engineers first build several models of the ship as the model could help the engineers by providing them a prototype to build of so that they have an idea of what or how the ship will looks like, and if they test it, they could troubleshoot and see the errors or successes of the model of the ship.

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.

Answer:

The age of the rock is 5 million years

Explanation:

Fraction of radioactive substance remaining = 6.25% = 625/10000 = 1/16

Number of half-lives undergone by the substance to leave behind 1/16 of the original sample

1/16 = (1/2) * (1/2) * (1/2) *(1/2)

Therefore, the substance have decayed 4 times

One half=life = 1.25 million years

Four half-lives = 4 * 1.25 million years = 5 million years

Therefore, the age of the rock is 5 million years

Answer:

green

Explanation:

Answer and explanation:

Although they share some similarities because they are both eukaryotes, plant cells and animal cells are quite different from each other, which is logical since they have distinct lives.

For example, animal cells and plant cells both have a cell membrane, but only the plant cells have a cell wall - which is thick and resistant, and this makes sense because they are more exposed to mechanical and osmotic stress.

Since animals can move towards sources of water but plants cannot, there's also a way in which plants store water in the cells: vacuoles. Animal cells have vacuoles as well although they are much smaller than the single huge vacuole that plant cells have.

All living organisms need the energy to sustain different cellular processes. The organelle in charge of the chemical reactions behind the obtention of energy is the mitochondria, which is present in all cells, but the mitochondrion needs a specific substrate: glucose. Glucose is obtained in diverse ways: animals move and find food that contains glucose in it, while plants produce their own glucose with a specific process called photosynthesis, for which they need an organelle called chloroplast, which animals do not have. In order to transform the glucose into energy, the mitochondria end up generating CO2, which animals expel from their bodies by exhaling. This CO2, now in the air, is used by plant cells as a substrate in photosynthesis (which needs sunlight as well) to produce glucose and also O2, that will be inhaled by animals and used by their tissues.

All living organisms have one thing in common: they possess DNA. DNA contains all of the genetic information of an organism, and it is present in almost every cell of that organism -if it happens to be a multicellular being-. While prokaryotes have their DNA condensed into a single circular chromosome, eukaryotes like plants and animals, have their DNA form many linear chromosomes (quantity varies according to the species) and these chromosomes are inside a very specialized organelle: the nucleus, which prokaryotes do not have.
