Answer:Mars, has a thin atmosphere composed of about 95 percent carbon dioxide

Explanation:The leading theory is that Mars' light gravity, coupled with its lack of global magnetic field, left the atmosphere vulnerable to pressure from the solar wind, the constant stream of particles coming from the sun.

Answer:

Explanation:

Mercury’s atmosphere containing oxygen (42%), sodium (29%), hydrogen (22%), helium

(6%), potassium (0.5%) and water vapor.

2. Venus

The atmosphere of Venus is one of the most chemically complex and dynamically active

planetary atmosphere in the solar system. The Venusian atmosphere consist of carbon

dioxide (95.5%), nitrogen (3.5%), sulfur dioxide (0.015%), argon (0.007%), carbon monoxide

(0.002%), helium (0.001%), neon (0.001%).

3. The Earth

The atmosphere of Earth is mainly composed of nitrogen (78.08%) and oxygen (20.95%).

The remaining part of the atmosphere divided into the permanent and the variable

constituents. The permanent constituents consist of the five noble gases, argon, neon,

helium, krypton and xenon also other materials such as carbon dioxide, hydrogen, methane,

nitrous oxide and radon. The variable constituents of the atmosphere are water, carbon

monoxide and ozone.

statuscvo [17]

Answer:

Evolution is the process that allows the appearance and elaboration of signals, but the key question is: what selective forces led - and lead - to the appearance of color characteristics and chromatic patterns ?, not only in the scope of a species concrete - such as the black bib of the common sparrow (Passer domesticus) - but also within each family or even within a wider framework, for example the light colored spots that we see in the outer feathers of the tail of the bird species Dr. Senar explains the methods and results of the experiments performed so that the reader can compare their interpretation with the scientific advocacy, but also involve other alternative hypotheses. For example, the supposed signals of dominance Do they represent correlations with age and sex, which in turn correlate with dominance? And what can we say about deception, of those signs that exaggerate the status of an individual? The presentation of the different alternatives offers the reader the opportunity to detect the complexity of the selective forces and the difficulty of designing clear and conclusive experiments. In a similar way, the author presents the multiple hypotheses that address sexual selection and delayed maturation of plumage, thus facilitating the reader, understanding of the different topics discussed and a better appreciation of the elegant experiments that have been used to formulate and defend some of these hypotheses. Camouflage is treated in a separate chapter, but Dr. Senar not only focuses on the colors of the prey, which affects the object of investigations, but also on the color of predators, whose study has been the subject of much attention minor The interpretation of color as a bioindicator is an innovative approach that is proposed towards the end of the book. This is the first time that this possibility was raised, but, as the author points out, if the birds determine the quality of the habitat by the color of the potential couple that lives in it, there is no doubt that we should also be able to determine the quality of a habitat using similar means. Experiments that allow us to evaluate this approach are described throughout the book.

Answer:

secondary structure

Explanation:

Alpha helices and beta sheets are two main structural forms in secondary structure of proteins. This structures are formed spontaneously. The next step of protein structure formation is folding into tertiary three-dimensional form.

In diseases such as CJD and kuru, protein prion is changed in structure. It is not known how degeneration of priones protein structure occurs, but it can lead to neurodegenerative diseases which can even be fatal.

Priones are also known as proteinaceous infectious particles.

What are the characteristics of an indicator species

LenKa [72]

An indicator species is an organism whose presence, absence or abundance reflects a specific environmental condition. Indicator species can signal a change in the biological condition of a particular ecosystem, and thus may be used as a proxy to diagnose the health of an ecosystem.

Which of the following best describes a benefit of one type of nonrenewable energy?

STALIN [3.7K]

Answer:

" Natural gas does not produce greenhouse gases as other energy sources do."

Explanation:

The answer, "Coal deposits are found on nearly every continent and mining coal poses few risks." shows only how it can be a better option, but does not show how it can benefit.

The answer, "Petroleum is relatively inexpensive compared to other forms of energy." only shows how it can be a better option, but does not show how it can benefit.

The answer, "Nuclear power increases water vapor in the atmosphere." does not clearly state how this benefits us.
