The Image Depicts The Impact Of A Mutagen On The Phenotype Of F1 And F2 Offspring In Nematodes, A Common

Answers

Answer 1

Answer:

A, D, E

Explanation:

just did it

Answer 2

The arguments that can be made based on the information in the model are as follows:

The mutated DNA is a recessive allele. The mutagen altered the DNA of the worm in the parental generation. The DNA altered by the mutagen occurs in gamete cells and is passed to offspring.

Thus, the correct options for this question are A, D, and E.

What is Mutagen?

Mutagen may be characterized as a type of agent that possesses the capability to induce mutation within the genetic segment of living organisms. Mutagens are of two types, they are:

Physical mutagens: UV radiations.Chemical mutagens: Chemicals like ethidium bromide.

According to the context of this question, mutation can only be inherited from parent to offspring, if it is induced within the gamete cells of parents. While during the course of life, the mutation also induces in the genomic sequence of an individual.

Therefore, the correct options for this question are A, D, and E.

Select the statement that describes the major site where antiviral action is blocked by the protease inhibitors. Select one: a. The protease inhibitors block the ability of the human immunodeficiency virus from attaching and entering the cell membrane. b. The protease inhibitors block the uncoating process of the human immunodeficiency virus by binding to protease. c. The protease inhibitors block the nucleic acid synthesis of the human immunodeficiency virus. d. The protease inhibitors inhibit the late protein synthesis and processing of the human immunodeficiency virus.

Answers

Answer:

d. The protease inhibitors inhibit the late protein synthesis and processing of the human immunodeficiency virus.

Explanation:

Protease inhibitors are antiviral agents used to fight against pathogenic viruses such as retroviruses (e.g., human immunodeficiency virus, HIV) and RNA viruses (e.g., hepatitis C virus). Protease inhibitors can drastically reduce the viral load. Protease inhibitors may target 1-virus-encoded proteases which are responsible to produce functional proteins from polyprotein precursors and 2-processing structural proteins that are required for virus assembly. Some examples of protease inhibitors include, among others, ritonavir and indinavir, which are used in patients with HIV infection.

write two examples of consumers tell whether they are herbivores omnivores carnivors or scavengers

Answers

Answers

Lion,Tiger -Carnivores

vulture- scavenger

Cow,sheep -Herbivores

Man, Pig -Omnivores

A panda (herbivore) eats bamboo shoots and leaves, while a lion (carnivore) preys on other animals.A bear (omnivore) eats both plants and animals, while a vulture (scavenger) feeds on the remains of dead animals.What are consumers?

In an ecosystem, consumers are organisms that obtain their energy and nutrients by feeding on other organisms. They are a vital part of the food chain, and they come in different sizes and types.

Consumers can be classified into several categories based on what they eat. For example:

Herbivores: These are animals that consume only plants for their food. Examples include rabbits, cows, and giraffes.

Carnivores: These are animals that consume other animals for their food. Examples include lions, tigers, and sharks.

Omnivores: These are animals that eat both plants and animals. Examples include humans, bears, and raccoons.

Scavengers: These are animals that feed on the remains of dead organisms. Examples include vultures, hyenas, and some types of beetles.

Consumers play an important role in an ecosystem, as they help to transfer energy and nutrients from one level of the food chain to another. They are an integral part of maintaining the balance and stability of an ecosystem.

- Cyanide is a strong cytochrome c oxidase inhibitor. Cytochrome c is the last enzyme in the
electron transport chain. If cell is exposed to cyanide, most of the cyanide will be found in which
of the organelles?​

Answers

Cyanide binds to Fe3+ in heme-containing proteins. This inhibits the terminal cytochrome complex IV of the electron transport chain. The blocklock of complex IV by cyanide depletes ATP culminating in cell death. Oxygen is unable to reoxidize the reduced cytochrome a3. Thus, cellular respiration is inhibited, as well as ATP production, in essence depriving the cells, tissue, and, ultimately, the whole body of oxygen. Hypoxia evolves into metabolic acidosis and decreased oxygen saturation. The extent of lactic acidosis indicates the severity of the cyanide poisoning. In a collapsed individual, plasma lactate is an indicator of cyanide poisoning. In severe cyanide poisonings, up to 98% of the cyanide in the bloodstream is tightly bound to red blood cells. The ancillary response is myocardial depression and decline in cardiac output. Bradycardia, hypotension, and cardiac arrhythmia then develop into VF and cardiovascular collapse.

Teniendo en cuenta problemáticas de la biología o de su aprendizaje ,pensar un tema investigar desde el enfoque cualita tivo y otro desde el enfoque cuantitativo

Answers

Answer:

Caso de estudio: El efecto de estresores ambientales sobre el comportamiento animal

- Ejemplo de un tipo de estudio cualitativo: la influencia de estresores ambientales (por ej. niveles anormales de dióxido de carbono atmosférico) sobre el comportamiento en ratones de laboratorio  

- Ejemplo de un tipo de estudio cuantitativo: la influencia de estresores ambientales sobre los niveles de producción de hormonas asociadas a cambios comportamentales en ratones de laboratorio  

Explanation:

Un enfoque cualitativo se caracteriza por el hecho de que la información obtenida durante dicho estudio se agrupa en categorías mutuamente excluyentes. En biología, los estudios de tipo cualitativo generalmente se caen dentro de la dicotomía observacional (es decir, presencia o ausencia del factor en estudio). En el ejemplo arriba citado, es posible obtener datos relacionados a uno o más determinado aspectos comportamentales en los individuos bajo estudio (por ejemplo, presencia o ausencia de signos de irritabilidad) en ratones sometidos a algún estresor ambiental (por ejemplo, niveles anormales de CO2 atmosférico). Por otra parte, en un enfoque cuantitativo, la información se recopila en intervalos obtenidos a partir de operaciones aritméticas (estadística paramétrica). En el ejemplo, los datos obtenidos pueden ser clasificados en intervalos referidos a los niveles hormonales. Esta información resulta útil para determinar si las diferencias en los niveles hormonales entre individuos que se encuentran en presencia del estresor ambiental son estadísticamente significativas respecto al grupo control (individuos desarrollados en un ambiente con niveles normales de CO2 atmosférico), y de este modo concluir si el estresor ambiental puede o no modificar variables comportamentales. Los estudios cualitativos permiten el uso de variables independientes las cuales son clasificadas como cualitativas (discretas).
