Answer:

The type of adaptations of the Toucan and Monstera Plant are physical adaptions. Both of these adapted physical characteristics help these organisms to survive.  The difference in their physical adaptation is that in the Toucan, the physical characteristic helps the Toucan consume nutrients. Meanwhile, the adaptation of the Monstera Plant helps prevent harmful things such as mold.

Answer: The human body contains trillions of microorganisms — dwarfing human cells by 10 to 1. Due to their little size, nonetheless, microorganisms make up just around 1 to 3 percent of the weight's (in a 200-pound grown-up, that is 2 to 6 pounds of microscopic organisms), yet assume a crucial function in human wellbeing.  In 2016, a survey of over forty years of examination into the human microbiome found that there is zero logical proof to back this frequently refered to tidbit up. Rather, the proportion appears to be about 1.3-to-1, with the normal human playing host to around 100 trillion microorganisms, plus or minus. Rather, the proportion seems to be about 1.3-to-1, with the normal human playing host to around 100 trillion organisms, plus or minus.

Explanation:

You can mix this up and paraphrase this into ur own words.

The microorganisms that are present and live in the human body are 1 to 10 micrometers.

Microorganisms are tiny living organisms that can be only seen by microscopes. These organisms are found everywhere on earth. They are free-living and parasitic. There are good and bad microorganisms.

Some are useful to the earth and the living creature, but some are harmful to the health of other living creatures. They are responsible for many diseases in plants, animals, and other organisms.

There are many bacteria present inside the body. They are present in the digestive system, and our mouth. They help in the digestion and breakdown of many food materials and macromolecules.

Thus, the size of microorganisms that are present and live in the human body is 1 to 10 micrometers.

Answer:

If given a choice between blood cells, hemoglobin, plasma, platelets, the correct answer would be hemoglobin. Otherwise, the correct answer is hemoglobin.

To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Explanation:

4CO2 also known as 4CO2 is a chemical compound occurring as an acidic colorless gas with a density about 53% higher than that of dry air. Carbon dioxide molecules consist of a carbon atom covalently double bonded to two oxygen atoms. It occurs naturally in Earth's atmosphere as a trace gas. It also helps trap earths heat inside the earth so i doesnt escape back to outer space.

yourwelcome goodluck ill peel my eyes out if need help again- an 8th grader :p

Carbon dioxide is formed by the covalent bonding of carbon and two oxygen atoms. Thus it is a having the formula CO₂. 4CO₂ means 4 moles of carbon dioxide.

Carbon dioxide is an inorganic gas formed by the covalent bonding of carbon and oxygen. The valency of carbon is four and the valency of oxygen is two. Thus carbon shares its electrons two to each oxygen.

Each oxygen in turn shares its two electrons with carbon. Thus both the atoms attains stability. Carbon dioxide is a nonpolar compound with the formula CO₂. Thus one mole of carbon is represented as CO₂.

One mole of CO₂ weighs 44 g. Hence, the molar mass of carbon dioxide is 44 g/mol. As any other compounds one mole of carbon dioxide contains Avogadro number of atom or 6.022 ×10²³ CO₂ molecules.

4 CO₂ indicates 4 moles of CO₂ having 4  × 6.022 ×10²³ =24.08 ×10²³ molecules.

Answer: Jewelers add different metals to strengthen the material and improve durability during wear. The resulting mix of two or more metal elements is called an alloy. For instance, pure silver bends and scratches quite easily. A metal alloy for jewelry, like sterling silver, is a better solution for most applications.

Answer:

I hope its correct! here is what I found.

An alloy is a mixture of two or more elements, at least one of which is a metal. Alloys are created to give the resulting material improved properties such as increased strength, improved corrosion resistance, or improved electrical conductivity.

Jewelers use alloys in jewelry for several reasons. One is that many pure metals are too soft to be used in jewelry, so alloys can be used to increase the strength of the metal. Additionally, many pure metals are not suitable for jewelry because they are too expensive or too difficult to work with. For example, gold is too soft in its pure form, so jewelers will often alloy it with other metals like copper and silver to make it stronger and more suitable for use in jewelry. Alloys can also be used to change the color of the metal. For example, by alloying gold with copper, jewelers can create rose gold.

The element that has been reduced in the redox reaction \(AgNO_3 + Na NaNO_3 + Ag\) is silver (Ag). A redox (reduction-oxidation) reaction involves the reduction of one element by the gain of electrons and the oxidation of another element by the loss of electrons.

When sodium (Na) loses one electron to generate \(NaNO_3\) in this reaction, sodium changes from its neutral state (with a zero oxidation number) to a positive oxidation state (+1). On the other hand, when silver (Ag) in AgNO3 gets one electron to create Ag, it moves from a +1 oxidation state to a neutral state (with zero oxidation number).

Silver is the element that undergoes reduction in this process because reduction entails a gain of electrons, reducing it from its +1 oxidation state to its neutral state.

Answer:

Georgia

Population: 10,729,261

Nonrenewable resources: 32%

Renewable resources: 12%

Nuclear energy: 24%

Renewable resources used the most: Biomass

Interesting fact: Georgia is the national leader in electricity generation from biomass.

Biomass is organic matter that comes from plants and animals. It can be used to generate electricity, heat, and fuel.

Biomass can be burned directly to generate electricity, or it can be converted into a liquid or gas that can be burned in a power plant.

Biomass is a renewable resource, which means it can be replaced over time. It is also a clean-burning fuel, which means it does not produce air pollution.

Biomass can be expensive to produce and transport. It can also be difficult to store and manage.

Biomass is a promising source of energy, and it is likely to play an increasingly important role in the future.

You can help by using less energy in your home. You can also support the development of renewable energy sources, such as biomass.

The statement that best describes which traits are expressed by an organism is A.

An organism expresses all the traits for which it carries genes. This is because an organism's traits are determined by the combination of genes it carries, which includes both dominant and recessive genes. Even if a trait is not expressed in an organism, it can still be carried in its genes and passed on to its offspring. Therefore, all the traits for which an organism carries genes have the potential to be expressed in either the organism or its offspring.

B-An organism expresses only the traits whose genes are inherited from a parent.
