what makes a molecule a saturated fat?

Answer: The name given to elements with the same number of protons but differing numbers of neutrons is Isotope.

Explanation:

When the two different atoms of same element having same number of protons but are differing number of neutrons than those elements are known as isotopes of that element.

For these species, atomic number remains the same but atomic mass differs.

For Example:

[tex]_{17}^{35}\textrm{Cl}\text{ and }_{17}^{37}\textrm{Cl}[/tex] are the two isotopes of chlorine having different masses and same atomic number.

Hence, the correct answer is isotopes.

The terms h​eterogeneous and homogeneous refer to mixtures of materials in chemistry. The difference between heterogeneous and homogeneous mixtures is the degree at which the materials are mixed together and the uniformity of their composition.

A homogeneous mixture is a mixture where the components that make up the mixture are uniformly distributed throughout the mixture. The composition of the mixture is the same throughout.

There is only one phase of matter observed in a homogeneous mixture.

You can't pick out components of a homogeneous mixture or use a simple mechanical means to separate them. You can't see individual chemicals or ingredients in this type of mixture. Only one phase of matter is present in a homogeneous mixture.

A heterogeneous mixture is a mixture where the components of the mixture are not uniform or have localized regions with different properties. Different samples from the mixture are not identical to each other. There are always two or more phases in a heterogeneous mixture, where you can identify a region with properties that are distinct from those of another region, even if they are the same state of matter (e.g., liquid, solid).

Usually, it's possible to physically separate components of a heterogeneous mixture. For example, you can centrifuge (spin out) solid blood cells to separate them from the plasma of blood. You can remove ice cubes from soda. You can separate candies according to color.

Nancy's ability to run without watching her feet and hit a baseball without focusing on the bat is due to proprioception. It is a biological sense that allows perception of the location and movement of our body parts in space, enabling people to perform tasks without consciously focusing on them.

The ability of Nancy to perform these tasks without consciously focusing on them can be attributed to a concept in biology known as proprioception. Proprioception is the sense that lets us perceive the location, movement, and action of our bodies and its parts in space, even without looking at them. It's what allows us to do things like touch our nose with our eyes closed, run without watching our feet, or hit a baseball without focusing on the bat. When Nancy runs or swings a bat, her body is sending continuous feedback to her brain regarding the position and movement of her limbs and muscles. This feedback, interpreted by the brain, enables her to adjust her movements and perform the desired action even without consciously focusing on it.

Final answer:

A cell at the end of G₁ phase has grown and accumulated building blocks of DNA, while a cell at the end of G₂ phase has replenished energy stores, synthesized proteins, and completed preparations for mitosis.

Explanation:

At the end of the first phase of the cell cycle, known as G₁ phase, a cell has grown and carries out normal metabolic functions. It is accumulating the building blocks of DNA and energy reserves to replicate each chromosome in the nucleus. At the end of the second phase, known as G₂ phase, the cell has replenished its energy stores, synthesized proteins for chromosome manipulation, and duplicated some organelles. It has completed the necessary preparations for the mitotic phase, which involves nuclear division in mitosis and division of the cytoplasm in cytokinesis.

Final answer:

A cell in the G2 phase is preparing for mitosis by replenishing energy and synthesizing necessary proteins, while a cell at the end of the mitotic phase has completed cell division, resulting in two identical daughter cells.

Explanation:

A cell at the end of the first phase of the cell cycle, known as the G2 phase, differs from a cell at the end of the second phase or the mitotic phase in several ways. During the G2 phase, the cell is preparing for mitosis by replenishing its energy stores, synthesizing proteins for chromosome manipulation, duplicating some organelles, and dismantling the cytoskeleton to provide resources for the mitotic spindle. Additionally, there might be additional cell growth during G2.

At the end of the mitotic phase, which consists of mitosis and cytokinesis, the cell has successfully divided to form two identical daughter cells. During mitosis, the duplicated chromosomes are aligned, separated, and moved to opposite poles of the cell. Cytokinesis then divides the cytoplasm, completing the formation of two separate daughter cells.

These stages are tightly regulated by internal and external signals. Failure in these signals can cause uncontrolled cell division and potentially lead to cancer.

Glucose is a monosaccharide whereas ATP is energy carrying molecule.

Glucose is a monosaccharide which is made of six carbons while on the other hand, adenosine triphosphate (ATP) is energy carrying molecule which is formed from phosphate which releases energy that is used by the body for doing various activities.

Glucose is used by the mitochondria of the cell where it can be broken down in order to release energy in the form of ATP molecules that can be used by the cells for different activities.

Final answer:

Water's polar covalent bonds create a slightly positive and negative charge, allowing it to dissolve ionic compounds by forming hydration shells around the ions. In a solution of salt in water, water is the solvent and salt is the solute.

Explanation:

Part A: Polar Covalent Bonds in Water and Solubility

Water molecules have polar covalent bonds because of the difference in electronegativity between hydrogen and oxygen atoms. This creates a dipole moment with oxygen having a partial negative charge and hydrogen atoms having a partial positive charge. The ability of water to dissolve many substances, such as ionic compounds like salt, is due to these polar covalent bonds.

When salt is added to water, its ions (sodium and chloride) are attracted to the opposite charges on the water molecules, leading to the formation of hydration shells. This is why the sodium ions are surrounded by the partially negative oxygen ends of the water molecules, while the chloride ions are surrounded by the partially positive hydrogen ends. The formation of these spheres of hydration effectively separates the ions in the solvent, hence dissolving the salt.

Part B: Solvent and Solute Identification

In the solution created from the dissolving of salt in water, water acts as the solvent, which is the substance doing the dissolving. Salt (sodium chloride, NaCl), is the solute, which is the substance that is dissolved.

In matrix the cell does the second stage of cellular respiration take place.

The Krebs cycle, also known as the citric acid cycle, is a biochemical pathway (a series of biochemical reactions) and the second stage of cellular respiration.

Cellular respiration is a series of pathways designed to convert food into available energy for the cell. It is often called aerobic respiration because it occurs in the presence of oxygen.

Humans also have the ability to perform anaerobic respiration or fermentation. This is the conversion of sugar into lactic acid in the absence of oxygen. Anaerobic respiration enables the body to make relatively small amounts of energy even when the body cannot produce sufficient amounts of oxygen.

Therefore, In matrix the cell does the second stage of cellular respiration take place.

To estimate the total number of nests in Florida, researchers could conduct a survey or census of selected areas and extrapolate the total based on the proportion observed in the surveyed areas.

To estimate the total number of nests in Florida, one approach could be to conduct a survey or census of selected areas in the state. Researchers could choose representative areas and count the number of nests they observe in those areas. They could then extrapolate the total number of nests in Florida based on the proportion of nests observed in the surveyed areas.

For example, if researchers surveyed five different areas and observed a total of 100 nests, and if they know that those areas represent 10% of the total suitable nesting habitats in Florida, they could estimate that there are approximately 1000 nests in Florida (100 nests / 0.1).

It is important to ensure that the surveyed areas are representative and that the counting methods are accurate to obtain reliable estimates.

A researcher can estimate the total number of nests in Florida by using sampling techniques like quadrat sampling or line transect methods to count nests in representative areas and extrapolate these numbers to a larger scale. The mark and recapture method, if adapted for nests, and growth rate trends from existing studies can also be useful in making these estimates.

To estimate the total number of nests in Florida, a researcher might use a variety of methods, including direct counts, sampling, and extrapolation based on known densities. Direct counts would involve physically counting all nests in a given area, but this is often impractical for large geographic regions like Florida. Instead, sampling techniques such as quadrat sampling or the line transect method can be used to count nests in representative areas and then extrapolate these numbers to estimate the total number of nests across the state.

Another effective technique is the mark and recapture method, which, although it is more commonly used for estimating animal populations, could theoretically be adapted for nest counts if one can mark and later identify previously counted nests. Data indicating an average growth rate in nest numbers, such as the 36% yearly increase observed in a previous study noted in Box 15.6 Table 1, can also inform estimates of total nest numbers over time.

Explanation:

Responsiveness is an organism's ability to adjust to changes in its environment, while homeostasis is an organism's ability to maintain a stable internal environment despite changes in external conditions. As an example, pulling a hand away from something hot showcases responsiveness, whereas maintaining body temperature in cold conditions is an example of homeostasis.

The terms responsiveness and homeostasis both refer to certain physiological functions in organisms, but they represent different concepts.

Responsiveness, also known as irritability, is the ability of an organism to adjust to changes in its internal or external environment. For example, if you touch something hot, your body responds by pulling your hand away. This is an example of responsiveness.

On the other hand, homeostasis is the ability of an organism to maintain a stable internal environment despite changes in external conditions. Your body does this by controlling its temperature, pH level, glucose level, and other variables. For instance, when it's cold outside, your body maintains its internal temperature, this is an example of homeostasis.

The right answer is C. must be plant cells.

The bacteria certainly have a wall but do not have organelles.

Animal cells have no wall.

The plant cells are the very numerous elementary units constituting the vegetable organisms.

They generally comprise a cell nucleus surrounded by a cytoplasm, various organelles or plastids, all protected by a cell membrane. They can measure between 10 and 200 μm.

Plant cells are living systems. They are very different from the cells of organisms belonging to other eukaryotes. The main distinguishing features are:

*Large central vacuole (surrounded by a membrane, the tonoplast), which maintains the turgor of the cell and controls the exchange of molecules between the cytosol and the sap. These vacuoles serve as bins for plant cells, at the end of cell life, these vacuoles take up 90% of the cell space.

*A pectocellulosic wall made of cellulose and proteins, as well as lignin in many cases, and deposited by the protoplast outside the cell membrane. It is opposed to the cell wall of fungi, made of chitin, and prokaryotes, made of peptidoglycans.

*Plasmodesms, connecting the pores of the cell wall, which allows each plant cell to communicate with adjacent cells. This system is different from the network of hyphae present in fungi.

*Plastids, especially chloroplasts, which contain chlorophyll, the pigment that gives plants their green color and is involved in the process of photosynthesis.

*The absence of centrosomes that are present in animal cells.
