Plant cells are protected from the harmful effects of excessive light energy and reactive oxidative molecules by Carotenoids.
Along with chlorophylls, carotenoids are essential pigments in photosynthetic organs.
The plant is shielded from UV (ultraviolet) damage by carotenoids. They actually prevent UV-induced free radical formation in the photosynthetic membrane, making them antioxidants and protecting agents. In PSII complexes, their ability to quench 3Chl and 1O2 has been demonstrated in vitro. In non-photosynthetic plant organs, carotenoids also play roles as photo protectors, antioxidants, color attractants, and plant hormone precursors.

9- The results of this type of DNA analysis are often used to help
determine *
A) the number of DNA molecules in an organism
B) if two species are closely related
the number of mRNA molecules in DNA
OD) if two organisms contain carbohydrate molecules
Answer:
B) if two species are closely related.
Explanation:
DNA analysis is used to determine the relationship between two species in order to check their relations with each other because DNA molecules has all the information about the organisms. If there is more similarities between two organisms so they are more closely related to each other while on the other hand, if there is no similarities between two species so we can say that there is no relationship exists between two organisms or species. All this discussion describes the usefulness of DNA analysis.

How does your nose filter the incoming air?
Answer:
Air enters through the nostrils of the nose and is partially filtered by the nose hairs, then flows into the nasal cavity. The nasal cavity is lined with epithelial tissue, containing blood vessels, which help warm the air; and secrete mucous, which further filters the air
Explanation:
Con ayuda de un microscopio se observa una bacteria en el agua transcurridas (2) se miran muchas bacterias . Que ocurrio alli ,que tpo de reproducccion sucedio meiosis o mitosis
Answer:
Ninguna de las dos. No ocurre ni mitosis ni meiosis.
Probablemente haya ocurrido fisión binaria/bipartición.
Explanation:
En este caso estamos hablando de bacterias, organismos unicelulares procariotas. Estos tienen una forma de reproducción asexual denominado fisión binaria. Los eucariotas por su parte pasan por periodos de división celular implicada en el crecimiento denominado mitosis, y división celular implicada en reproducción sexual, denominada meiosis.
La fisión binaria, también conocida como bipartición, si bien muy parecida a la mitosis en algunos aspectos, es la forma de reproducción de las bacterias.
Ambas, mitosis y fisión binaria, implican un duplicado de material genético. El ADN se duplica y una copia va a cada célula hija. Lo mismo sucede con el resto del contenido celular. Finalmente ocurre citocinesis. Sin embargo, a diferencia de la bipartición, la mitosis requiere de mecanismos mucho mas complejos de duplicación celular e involucra también a la cariocinesis, ausente en bacterias.
La fisión binaria ocurre muy rápidamente, en un breve período de tiempo puede hallarse una diferencia considerable en la cantidad de células presentes en un sustrato, producto de esta división. Es por esto que el crecimiento que exhiben las bacterias como población, sigue un modelo exponencial.
Explain the role of aquaporins in the rapid movement of water through some cells
Answer:
In the early 1990s, aquaporins were discovered, and it was found that they can selectively control water movement into and out of cells. One of the critical functions of aquaporins is that while they allow the passage of water they prevent the passage of ions.
pls help i need answer asap! The digestive system is a group of organs working together to convert food into energy and basic nutrients that are transported throughout the body. Food passes through a long tube inside the body known as the alimentary canal, made up of the oral cavity, pharynx, esophagus, stomach, small intestines, and large intestines. Once food is chewed, the bolus is moved into the stomach for further digestion. Examine the Interconnections chart and select the body system that is responsible for moving the food from the start to the finish of the digestive system.

Imagine a population of moths. White moths are easier for birds to see and eat. Black moths blend into their surroundings, so they are less visible to birds than white moths. As a result, black moths are more likely to survive and reproduce, enabling the gene for black coloration to be passed on to the next generation. This increases the frequency of genes for black coloration in the population. Which evolutionary process does this scenario describe
Answer:
The correct answer is - natural selection.
Explanation:
Natural selection is a process of adapting according to the environmental change in order to survive and reproduce and increase their number. It is represented by Darwin for the first time. Natural selection leads to evolution.
In this case, White moths adapt according to the environment by increasing the population of black moths in order to blend with the surrounding and as the result, black moths are more likely to produce and survive and passed this trait to the next generation.

4. Explain why the cave appears black.
Answer:
Caves normally apear black. Yes, this is because in a cave there are no natural sunlight or lights in a cave. For example, If your room was all dark it would look black...yes. Same with a cave! It will appear black as well. So, as you can see, Caves appear black because it is so very dark inside no lights nothing. So that is why it looks black.

El aparato digestivo de los cocodrilos, adaptado para ingerir una gran variedad de presas es una adaptación de tipo?
La respuesta correcta para esta pregunta abierta es la siguiente
A pesar de que no anexaste opciones o incisos para responder, podemos comentar lo siguiente.
El aparato digestivo de los cocodrilos, adaptado para ingerir una gran variedad de presas es una adaptación de tipo evolutivo morfológico.
Esto significa que a través de los años, la evolución de los cocodrilos los ha llevado a ajustar sus órganos, tal y como es el caso del aparato digestivo.
Esta capacidad de adaptación es una de las tantas maravillas de la naturaleza que permite la adaptación de los organismos de los animales a las necesidades que tienen y los hábitats donde viven, para que puedan sobrevivir cazando los tipos de animales que comen para poder sobrevivir en sus estados naturales.
What do you need to create a chemical bond?
Answer:
A strong chemical bond is formed from the transfer or sharing of electrons between atomic centers and relies on the electrostatic attraction between the protons in nuclei and the electrons in the orbitals. The types of strong bond differ due to the difference in electronegativity of the constituent elements.
