Answer: I agree with Dr. Walker and his colleagues that the changes to Jordan Jones’s meal could not explain his improved performance.
Explanation: I agree with Dr. Walker and his colleagues that the changes to Jordan Jones’s meal could not explain his improved performance because, food can´t change anything except for your hungriness, and the more food you eat the more fat you get, and not slim.
you have two bean burritos with the same ingredients. One burrito weighs 0.3 pounds, while the other weighs 0.5 pounds. After microwaving each of them for one minute, which burrito will be hotter? Explain your answer.
Answer:
the one that weighs less
Explanation:
the one that weighs less has less of the amount of ingredients in it which takes less long to cook and heats up faster
Answer:
0.3 pounds
Explanation:
I say that because since there is less weight on one of them, it doesn’t have to be cooked as long, or else it may get cooked TOO uh since it weighs less, while the other one may be cooked perfectly since there is more to cook.

What best explains why there's fewer secondary consumers than producers?
Answer:
because of inefficiency
Explanation:
The organisms that eat the primary consumers are meat eaters (carnivores) and are called the secondary consumers. ... Because of this inefficiency, there is only enough food for a few top level consumers, but there is lots of food for herbivores lower down on the food chain. There are fewer consumers than producers.

False. At the freezing point, the particles in an object have some kinetic energy.
False. On the Celsius temperature scale, there are negative numbers.
True. The more particles an object has at a given temperature, the more thermal energy it has.
False. Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.
False. When heat is absorbed by an object, the speed of the particles in the object is changed.
Explanation:
The temperature is defined as the measure of hotness and coldness.It is measured in terms of degrees Celsius, Kelvins, degrees Fahrenheit.There are negative numbers on the Celsius temperature scale and Fahrenheits temperature scale but not on the Kelvin temperature scale.It is a measure of the average kinetic energy of the particles of the object.The hotter the object, the higher will be the kinetic energy of the particles of the object, higher will be the value of temperature. The colder the object, the lower will be the kinetic energy of the particles of the object, lower will be the value of temperature.The object with more mass will have more particles and more will be the kinetic energy associated with the particles.When heat is added to an object to raise its temperature the kinetic energy of the particles increases. As kinetic energy is directly linked with speed or velocity.So from this, we can conclude that :
At the freezing point, the particles in an object have some kinetic energy.
On the Celsius temperature scale, there are negative numbers.
The more particles an object has at a given temperature, the more thermal energy it has.
Object A is much larger than Object B, but both are made of the same material. If both objects are at the same temperature, the thermal energy of Object A is not the same as the thermal energy of Object B.

Beavers are able to adapt to the changing conditions of all four seasons. Which of the following would threaten the survival of beavers?
A. hot temperature in July
B. freezing rain in
December
C. forest fire in October
D. snow in January
Answer:
C
Explanation:
The question says that beavers are able to adapt to changin questions in each season, so we know that snow in winter, or heat in summer won't bother them. These types of variations in weather are what the beaver is used to. This would eliminate A (July is in summer, so the beavers would expect heat), B (December is in winter, so the beavers would expect freezing conditions), and D (January is in winter, so the beavers expect the snow). That leaves us with C. Fires are not a typical condition for a season- fires aren't expected every fall. Therefore, when there is a fire, beavers will not know what to do.

why do you think are the reasons why only few seeds germinate
Answer:
The germination of a seed can eventually be affected by temperature, humidity and oxygen. Generally, the seeds remain viable longer at low temperatures, a humidity range of 3% to 20% and an environment with low partial pressure of oxygen. If some of these factors are not met, the seed can age or eventually germinate.
Explanation:
Seeds are the main reproductive organ of the vast majority of higher terrestrial and aquatic plants. They play a key role in the renewal, persistence and dispersal of plant populations, the regeneration of forests and ecological succession. In nature the seed is a staple food source for many animals. Seed germination often takes place on the surface of the soil, so the balance between the gain of soil moisture and its loss by transpiration to the atmosphere determines when the seed becomes saturated with moisture and begins to germinate.
The reasons why only few seeds germinate are as a result of some factors such as temperature, availability of water, depth of plant, presence of plant hormone (Gibberellin) in the seed. etc
Seed Germination is a process after seed dormancy where seeds sprout and develop into a new young plant. The reason why some seeds germinate and others do not are some of the following:
Temperature: For the germination of seed to occurs, seed needs to undergo a moderate amount of soil temperature. The cotyledon of the seedling gets destroyed when the seeds are being exposed to an extreme soil temperature. This is why most seed doesn't thrive in the deserts.
Availability of water: The soil in which seeds need to be planted must be moist and contain have a moderate amount of water holding capacity for the survival of the seed plant. The moderate amount of water holding capacity can be seen in humus soil.
Presence of plant hormone: The presence of Gibberellin in seeds helps the activation of the cotyledon to begin the germination process after the seed has absorbed water from the soil. In seeds where the enzymes are absent, such seeds do not germinate.

1. What two reactants enter the mitochondrion?
2. Compare the reactions in mitochondria with glycolysis.
1. How does a cell obtain energy?
2. Under what conditions does fermentation occur in a cell?
3. If a cell could perform both cellular respiration and fermentation, which process would benefit the cell more?
Answer:
1.NADPH2 and FADH2 , and O2
Explanation:
NADPH2 and FADH2 get oxidized in the electro transport chain into NADP+ and FAD+ and water and oxygen and yield 3 ATP molecules and 2 ATP molecules per each molecule respectively
Following are the answers:
The two reactants that enter the mitochondrion are pyruvate, the end product of glycolysis, and oxygen.In the mitochondria, pyruvate and oxygen undergo a series of reactions called cellular respiration, which produces energy in the form of ATP. This process is more efficient than glycolysis, which only produces a small amount of ATP.A cell obtains energy through a variety of processes, including cellular respiration and fermentation.Fermentation occurs in a cell when there is a lack of oxygen, such as in anaerobic conditions.In general, cellular respiration is more efficient than fermentation in producing ATP, but fermentation is a useful process for cells to produce ATP when oxygen is not available.What is mitochondria?Mitochondria are organelles found in the cells of most eukaryotic organisms, including plants, animals, and fungi. They are often referred to as the "powerhouses" of the cell because they are responsible for producing the majority of the cell's supply of adenosine triphosphate (ATP), which is used as a source of chemical energy.
Mitochondria are membrane-bound structures that contain their own genetic material, separate from the cell's nucleus, and are responsible for their own replication. They have unique characteristics that allow them to produce energy through the process of cellular respiration, a series of reactions that convert the energy from food molecules, such as glucose, into ATP. This process is one of the most important biological processes in living organisms, as it allows cells to perform their functions and sustain life.

Gene expression is influenced by many factors. Which of the following is a factor in gene
expression?
Answer:
Answer: The Environment.
Environmental factors, such as diet, medicines, or exposure to toxins, can change how genes are expressed.
What are factors affecting gene expression?Gene expression is the process through which a gene's information is used to create a functioning gene product, allowing it to produce end products like proteins or non-coding RNA and ultimately have an impact on phenotypes.
Expressivity can be impacted by a number of elements, such as genetic make-up, exposure to dangerous substances, other environmental effects, and age. Penetrance and expressivity both have a range: People who carry the gene may or may not exhibit the trait, and when they do, the trait's expression can take many different forms.
