plant cells are protected from the harmful effects of excessive light energy and reactive oxidative molecules by

Answers

Answer 1

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.

Explanation:

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

Answers

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.

What do you need to create a chemical bond?

Answers

A chemical bond is a force of attraction between atoms or ions. Bonds form when atoms share or transfer valence electrons. Valence electrons are the electrons in the outer energy level of an atom that may be involved in chemical interactions.

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.

the number of mRNA molecules in DNA
OD) if two organisms contain carbohydrate molecules

Answers

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.

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

Answers

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.
