relative dating is the process of determining if one rock or geologic event is older or younger than another, without knowing their specific ages
Answer:
Option C Index Fossil
Explanation:
Relative dating is in order of rocks layers. The layers are no longer horizontal, but geologists are able to determine their order.

What are at least two characteristics of RNA?
O Single stranded
O Present at nucleus and cytoplasm
O uracil instead of thymine
O All of the above
.
Answer:
Present at nucleus and cytoplasm
Answer:
Characteristic feature of RNA are as follow:
Ribonucleic acid“ RNA” is another nucleic acid type. Like deoxyribonucleic acid “DNA ” it is polynucleotide but several differences are found in their structure.
In RNA the pentose sugar is ribose not deoxyribose.
RNA contain uracil in place of thymine.
RNA ,generally single stranded with partially double stranded region due to the folding at back of its single chain.
RNA sevres as genetic material in many viruses.Thrre are three major classes of cellular RNA s which function during gene expression.
These are:
Messenger RNA (mRNA)
Transfer RNA (t RNA)
Ribosomal RNA (rRNA).
¿En cuál opción se muestra el papel del ser humano en la protección de la biodiversidad? A. Construir presas en ríos para cuidar a las especies nativas del ecosistema. B. Denunciar el comercio ilegal de especies ante las autoridades competentes. C. Comprar animales exóticos, pero verificar que no estén en peligro de extinción. D. Eliminar a los seres vivos que pueden picar a las personas, por ejemplo, las avispas y las culebras.
Answer:
B. Informar el comercio ilegal de especies a las autoridades competentes.
Explicación:
Informar sobre el comercio ilegal de especies a las autoridades competentes es una de las funciones del ser humano para la protección de la biodiversidad. Las personas comercian con especies ilegalmente para obtener más ganancias, pero causan daños a los organismos y la biodiversidad donde están presentes anteriormente. El comercio de especies provoca un desequilibrio en el ecosistema que afectó negativamente al medio ambiente.
¿Cuál es la importancia de la diversidad Genética?
Answer:
las razones más importantes para conservar la diversidad genética es el mantenimiento del potencial evolutivo de las especies pues dicha diversidad representa el reservorio de las posibles respuestas al medio (físico y biológico), posibilitando con ello su adaptación a los cambios del mismo; pero también es importante económicamente dado que es el sustrato biológico sobre el que actúa el proceso de selección que ha venido realizando nuestra especie desde su etapa primitiva de recolector de alimentos.
Explanation:
1. How are seasons connected to the annual CO2 cycle?
CO2 in the atmosphere decreases during the growing season and increases during the rest of the year, which leads to maximum buildup in April and May before photosynthesis begins to take over again.
There's more carbon dioxide in the winter and a bit less in the summer. That's the collective breathing of all the plants in the Northern Hemisphere. "Plants are accumulating carbon in the spring and summer when they're active, and they're releasing carbon back to the air in the fall and winter," Graven explains.

Give any 2 significance of nitrogen cycle to green plant
Nitrogen is the most abundant element in our planet’s atmosphere. Approximately 78% of the atmosphere is made up of nitrogen gas (N2).
Plant uptake of nitrogen compounds
Once nitrogen is converted into compounds like ammonium and nitrate, these can be taken up from soils by plants and then the nitrogen can be used to form macromolecules like proteins and nucleic acids.
Nitrogen is a crucially important component for all life. It is an important part of many cells and processes such as amino acids, proteins and even our DNA. It is also needed to make chlorophyll in plants, which is used in photosynthesis to make their food.
As part of these life processes, nitrogen is transformed from one chemical form to another. The transformations that nitrogen undergoes as it moves between the atmosphere, the land and living things make up the nitrogen cycle.
Fixation
Nitrogen in its gaseous form (N2) can’t be used by most living things. It has to be converted or ‘fixed’ to a more usable form through a process called fixation. There are three ways nitrogen can be fixed to be useful for living things:
What happens when an atom loses an electron
Answer:
An atom that gains or loses an electron becomes an ion. If it gains a negative electron, it becomes a negative ion. If it loses an electron it becomes a positive ion (see page 10 for more on ions).

D
Explanation:
because it have a shape like that and the optimum temperature is at 37 ish which Is right the other are not right.
Answer:
Option D
Explanation:
Because the max reaction rate of a majority of enzymes in homeotherms is about 40 degrees C, they will start to denature at higher temperatures. Of course enzyme activity will vary compared to other organisms, i think with these options that option D is your best bet.

Las plantas transforman la luz del sol a través de unas células llamadas: a) Estomas. b) Cloroplastos. c) Raíces. d)Clorofila.
Respuesta:
La respuesta correcta es: b) Cloroplastos.
Explicación:
Los cloroplastos son organelas que se encuentran en las células vegetales y son responsables de realizar el proceso clave para la supervivencia de estos seres vivos: la fotosíntesis.
La fotosíntesis consiste en la transformación de sustancias inorgánicas a materia orgánica gracias a la energía proveniente de la luz solar. Esta materia orgánica será utilizada para la producción de los nutrientes requeridos por las células de la planta.
Los cloroplastos constan de una envoltura conformada por dos membranas y por unas vesículas llamadas tilacoides donde se encuentran las moléculas que participan en la transformación de energía lumínica a energía química que ocurre durante la fotosíntesis, por ejemplo la clorofila (que es un pigmento verde que le da a la planta su característico color).

In the early days of germ theory, contagious diseases were thought to be caused only by fungi or bacteria. In the 1890s, Dmitri Ivanovsky filtered extracts from diseased tobacco plants and discovered that the disease could be transmitted to new plants through the filtrate. He hypothesized that something smaller than bacteria or fungi was responsible for the transmission of the disease. Which best explains how Ivanovskis work led to a change in the germ theory
Answer:
He tried to promote his hypothesis as a law.

A. Climate Change
B. Mechanical Weathering
C. Sediment Deposition
D. Karst Topography
Answer:
I think it's D. Karst Topography
Explanation:
Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves. It has also been documented for more weathering-resistant rocks, such as quartzite, given the right conditions.
Why do classification systems change over time?
Answer:
When scientist find new species that may have to change classification systems in order to accommodate them. DNA sequencing has also let us find out more about evolutionary relationships.

Answer:
The correct answer is - contains many genes for transcription factors that are present in cnidarians and bilaterian animals.
Explanation:
Placozoans are the simplest known metazoan organism known on earth and found in warm water and all over the globe. Placozoans are very small approximately 2 to 3 mm.
These are basal forms of marine free-living multicellular organisms. In the molecular studies, it is found that they have similar genes that are present in cnidarians and bilaterian animals for transcription factors.
