What advantages do flowers give angiosperms over gymnosperms?

Answers

Hey! Look what I found online.

In general, it makes the angiosperms more efficient in pollination and, therefore, in producing seeds. Most angiosperms have perfect or bisexual flowers, that is, both the male and female reproductive organs are borne on the same flower while these are separated in the gymnosperms. In the conifers which are gymnosperms, thousands of pollen grains will be needed to pollinate one female. The pollens are carried by the wind and having one pollen land exactly on the stamen is quite an impossibility. 

Many angiosperms have colorful petals. This attracts the insects and birds. As they move from one flower to another, they deposit the pollens on the stigma of another flower. The nectar that angiospermous flowers produce and the aroma emitted play the same role.

Explain how a GIS can model the relationship between a natural resource and an observed change. Include an example of a change in the availability of a specific natural resource and a specific observation of nature.

Answers

Answer:

Water in a river can be traced through GIS

Explanation:

With the improvement in observational tool, GIS technique has proved exceptionally helpful in tracing the natural resources. The pixels number and color help us to trace the changes in quantity as well as quality.

For example -

Suppose,  a river and its channel is being traced through GIS.

In year 1991, the number of pixels covering a certain area and of sky blue color signifies large volume , area of water and its good quality respectively

However, after 10 years  image of same are may show a change in previous observation such as reduction in number of blue pixels and also change in color from blue to red signifying increase in pollution level.

GIS can be used in analyzing the data that are related to the place where a natural resource is gotten.

A geographic information system is important as it helps in the capturing, storage, and display of the data that are related to a particular position on the surface of the Earth.

When natural resources are found in an area, the geographic information system can be used in getting further information about the area. A geographic information system can also be used in the management of natural resources as they give spatial data which are necessary to know the disasters that have taken place in such an area before.

In conclusion, GIS is beneficial in natural resource management.

The word part​ "brady-" in​ "bradycardia" is considered what part of a medical​ term?

Answers

brady means slow.it is a greek word


The correct term for the word part ""brady-"" in ""bradycardia"" is a prefix.

In medical terminology, words are often constructed from a combination of prefixes, suffixes, and root words.

The prefix ""brady-"" is derived from the Greek word ""bradys,"" which means slow. It is used in medical terms to indicate a condition characterized by slowness or a reduced rate. In the case of ""bradycardia,"" the term refers to an abnormally slow heart rate. The prefix ""brady-"" combined with the root word ""cardia,"" which pertains to the heart, clearly describes the condition as a slow heart rate.

Prefixes are an essential component of medical terminology as they modify the meaning of the root word and help to specify the exact nature of the medical condition or procedure being described.

Succession is _______. a. harmful to ecosystems b. a natural recovery process c. unnecessary for ecosystem recovery d. a one-time event

Answers

Hello! Succession is not really harmful to ecosystems and it’s not a one-time event, because things come and go overtime. Therefore, it’s not A or D. It is necessary for ecosystem recovery, because it’s needed to continue on with things, just like families reproduce to make family continue. It’s not that bad. It’s just a natural process that happens. The answer is B: natural recovery process.

Succession is a natural recovery process. So, the correct option is (B).

What is an ecosystem?

Ecosystem is the study of interaction between population or organisms and the environment. It is the structural and functional unit of ecology.

Examples of ecosystems are: aquatic ecosystem, coral reef, desert, forest, human ecosystem, littoral zone, marine ecosystem, rainforest, savanna, urban ecosystem and others.

It consists of two components:

1. Abiotic components

2. Biotic components

1. Abiotic components- It consists of non-living components. For Eg., rocks, soil, minerals, water sources, and the local atmosphere.

2. Biotic Components- it consists of living components which are of two types- Prokaryotic and eukaryotic cells. Eukaryotes having membrane bound organelles while prokaryotes lack membrane bound organelles.

Thus, succession is a natural recovery process. So, the correct option is (B).

The inability of an organism to produce certain proteins can occur when an organism is lacking an enzyme needed to combine

Answers

 Living organisms have enzymes which are capable of linking amino acids together by creating a peptide bond between the amino acids. This process takes place in the A and P site of ribosomes in the cell during translation.

One such enzyme is called peptidyl transferase. If an organism lacks such an enzyme,  synthesis of the proteins catalyzed by that particular enzyme in its cells will not take place. If amino acids cannot be joined together, then a polypeptide chain, which forms the primary structure of the protein will not be formed.

Of five major gaseous components of air, which is the only one to vary significantly in concentration from place to place and from day to day?

Answers

Water Vapor Let's look at the major gases in the atmosphere and see which one meets the criteria in the question. 1. Nitrogen - 78.09% and is by far the largest quantity of gas in the atmosphere. 2. Oxygen - 20.95% and is the 2nd most common gas in the atmosphere. 3. Argon - 0.93% All of the above gases are always gases under regular conditions and tend to remain fairly stable as to their percentages. 4. Carbon Dioxide - 0.04% This gas too is always a gas under normal conditions and tends to get evenly distributed through the atmosphere. You'll find higher local concentrations near burning carbon, but generally the concentrations remain fairly constant. 5. Water Vapor - Average of 0.4%, but ranges widely. Around sea level it's typically close to 1%, in deserts, it's close to 0%. So this component matches the criteria for the question.

Can you use tap water in oxygen concentrator

Answers

no you should not because it might be not harmful to you but can cause build up and malfunction in the oxygen concentrator

Final answer:

Tap water can contain impurities and is not recommended for use in an oxygen concentrator. Distilled water is the safer option to avoid damage to the equipment. Substances like NaDCC and chlorine dioxide are more related to drinking water disinfection rather than use in medical equipment.

Explanation:

When it comes to the use of tap water in an oxygen concentrator for medical purposes, it is generally advised to use distilled water instead of tap water. Tap water can contain minerals and other impurities that may harm the equipment or affect the quality of the oxygen produced.

In the context of drinking water disinfection, substances like chloramines, chlorine compounds, and sodium dichloroisocyanurate (NaDCC) are important for ensuring that water is safe to drink, especially in situations where the public water supply may be compromised.

While chloramine and chlorine compounds are commonly used, NaDCC is increasingly preferred for its ease of use and effectiveness, especially for military, camping, or emergency needs.

Chlorine dioxide is another agent used for disinfection. However, when talking about the maintenance and operation of an oxygen concentrator, manufacturers typically recommend using distilled water to prevent any build-up of these substances within the machine, which could potentially cause damage over time.
