Why male baby is larger than female baby?

Male babies are typically larger than female babies due to genetic and hormonal differences. Testosterone, a male sex hormone, leads to increased growth and muscle mass in males. Additionally, male infants tend to have a higher birth weight on average compared to females.

What are some disadvantages of the microscope?

Some disadvantages of microscopes include limited depth of field, potential distortion of the sample due to the lens, and the need for careful sample preparation and handling. Additionally, high-quality microscopes can be expensive and require maintenance and calibration.

What is the wealthiest country in the southern hemisphere?

Australia is considered the wealthiest country in the southern hemisphere based on factors such as GDP per capita, natural resources, and overall economic stability.

How many times more acidic or basic is a pH of 11?

Relative concentration [H+]1 / [H+]2 = 10-(pH1 -pH2) = 10-(7.0-11.0) = 104 =

= 10,000 times more basic than in pure water (pH=7.0)

[Remember that dividing concentrations is substracting both log value of concentration]

What is the formula of zeolite?

The formula of zeolite is typically expressed as Mx/n[(AlO2)x(SiO2)y]·zH2O, where M represents the cation, x and y are the number of atoms of aluminum and silicon, respectively, and n and z are the charge and number of water molecules, respectively. The specific formula may vary depending on the type of zeolite.

Could some one Descibe the abiotic and biotic factors that affect the ecosystem?

Abiotic factors of a ecosystem are physical non living ones such as the weather, soil, a river, anything that's a not living.

Biotic factors include biological influences on organisms such as the types of plants growing, and the species of animals in the ecosystem, and any factor that's living.

Together abiotic and biotic factors determine the survival and growth of and organism.

How can you transform hydrogen to water?

Hydrogen is generally eliminated from water by electrolysis. The specific mechanism of the reaction is oxidation-reduction. The stoichiometric equation that governs the reaction is:

H+ + OH- <--> H2O

The equilibrium of this reaction lies far to the right, so the water molecule is very stable and hydrogen formation is nonspontaneous. To force the reaction to the left side, we can run a current through the water with two electrodes from a battery. This can be simply done by twisting one end of a paper clip around each terminals of a 9-Volt battery and submerging the free ends in salt water. Gas will bubble off of both paper clips. The wire from the positive terminal will be the hydrogen. The other clip is bubbling chlorine gas from the ionization of the salt in the water.

What were some scientific discoveries in 1971?

In 1971, notable scientific discoveries included the identification of the first pulsar by Jocelyn Bell Burnell and Antony Hewish, the development of the first microprocessor by Intel, and the discovery of the first human retrovirus by Howard Temin and David Baltimore.

Which shaded area on the map was least industrialized in the second half of the 1800s?

The area least industrialized in the second half of the 1800s was typically the southern United States, particularly states like Mississippi, Alabama, and Georgia. These regions relied mainly on agriculture, with less emphasis on heavy industry compared to the Northeast and Midwest.

What birds of prey live in London?

Common birds of prey found in London include kestrels, peregrine falcons, and sparrowhawks. These birds are known to thrive in urban environments and can often be spotted in parks, green spaces, and along the river Thames.

How was the naming of organisms different before carolus linnaeus and how was the system difficult for scientists?

Before Linnaeus, organisms were given long, descriptive Latin names that varied widely and lacked consistency. This made it difficult for scientists to communicate and organize information about different species. Linnaeus introduced a binomial naming system (genus species) that simplified categorization and identification of organisms.

Who discovered the speed of sound?

The speed of sound was first accurately measured by Sir Isaac Newton in the 17th century. He determined that sound travels at around 343 meters per second in dry air at room temperature.

What things are made from plastic?

What is the percentage of water vapour found in the ear th's atmosphere?

The percentage of water vapour present in the earth's atmosphere is variable, it keeps changing from place to place as well as time to time. In rainy season it is very high but in the dry season it is very low.

How light reflects from aluminum foil?

Light reflects off aluminum foil due to its smooth surface. The aluminum foil has high reflectivity, meaning it can bounce back a high percentage of light that hits its surface. This property is why aluminum foil is commonly used in packaging, insulation, and as a reflective material in solar panels.

What is the full form of n c p?

The full form of n C r is "n choose r" which represents the number of ways to select r items from a set of n items without regard to the order of selection.

What plants found in frigid zones?

Some plants found in frigid zones include Arctic moss, Arctic willow, Arctic poppy, lichens, and alpine plants like saxifrage and heather. These plants have adaptations to survive the extreme cold temperatures and short growing seasons of frigid regions. They play a crucial role in maintaining the delicate ecosystems of these environments.

What is a nodal point?

A nodal point refers to a point in an optical system such as a camera lens where light rays intersect without creating any lateral displacement in the image. It is important in photography for ensuring that panoramas stitch together seamlessly.

What are the six steps in the scientific method?


  • Ask a Question
  • Do Background Research
  • Construct a Hypothesis
  • Test Your Hypothesis by Doing an Experiment
  • Analyze Your Data and Draw a Conclusion
  • Communicate Your Results

or


Question: The scientist then raises a question about what (s)he sees going on. The question raised must have a "simple," concrete answer that can be obtained by performing an experiment. For example, "How many students came to school today?" could be answered by counting the students present on campus, but "Why did you come to school today?" couldn't really be answered by doing an experiment. Hypothesis: This is a tentative answer to the question: a testable explanation for what was observed. The scientist tries to explain what caused what was observed. Prediction: Next, the experimenter uses deductive reasoning to test the hypothesis. Testing: Then, the scientist performs the experiment to see if the predicted results are obtained. If the expected results are obtained, that supports (but does not prove) the hypothesis.

In science when testing, when doing the experiment, it must be a controlled experiment. The scientist must contrast an "experimental group" with a "control group". The two groups are treated EXACTLY alike except for the ONE variable being tested. Sometimes several experimental groups may be used. For example, in an experiment to test the effects of day length on plant flowering, one could compare normal, natural day length (the control group) to several variations (the experimental groups).

When doing an experiment, replication is important. Everything should be tried several times on several subjects. For example, in the experiment just mentioned, a student scientist would have at least three plants in the control group and each of the experimental groups, while a "real" researcher would probably have several dozen. If a scientist had only one plant in each group, and one of the plants died, there probably would be no way of determining if the cause of death was related to the experiment being conducted.

The experimenter gathers actual, quantitative data from the subjects. For example, it's not enough to say, "I'm going to see how the dog reacts in this situation." Rather, in that experiment, the scientist might have a list of certain behaviors, and record how often each of the dogs tested exhibits each of those pre-defined behavior patterns. Data for each of the groups are then averaged and compared statistically. It's not enough to say that the average for group "X" was one thing and the average for group "Y" was another, so they were different or not. The scientist must also calculate the standard deviation or some other statistical analysis to document that any difference is statistically significant.

Additionally, principles of fluid dynamics are important in medical devices like dialysis machines and ventilators, which rely on the movement of fluids and gases. Finally, principles of mechanics and materials science are crucial in the design of prosthetics and implants to ensure their functionality and compatibility with the human body.

Does the temperature of a gas decrease when the volume increases?

Yes, if the gas is not in a closed container it will expand when the temperature is increased. If it is in a closed container, it cannot expand, so the pressure inside the container will increase.

Words with eco in it?

Eco- used as a prefix for words that relate to ecology or to the environment. Product or merchandise that name with "eco" usually means it's environment friendly.
