what is the effect of the abnormal protein on tissue function in duchenne muscular dystrophy and skeletal muscle tissue?
Answer:
Lack of the dystrophin protein in muscle cells causes them to be fragile and easily damaged. DMD carriers are females who have a normal dystrophin gene on one X chromosome and an abnormal dystrophin gene on the other X chromosome. Most carriers of DMD do not themselves have signs and symptoms of the disease, but a minority do. Symptoms can range from mild skeletal muscle weakness or cardiac involvement to severe weakness or cardiac effects and can begin in childhood or adulthood.

Compare and contrast suspension feeding and deposit feeding-
Answer:
Suspension feeding involves collecting food particles like small organisms, organic matter, detritus which are suspended in water, often using some form of filtration.
Suspension feeders catch food or organic material from the water using tentacles or spiny arms
where as
Deposit feeding involves feasting on detritus and organic matter that have settled on the ocean floor.
Deposit feeders pass sand, mud, water or sediment into their mouths using mucous-covered tentacles or arms etc.
Explanation:
Suspension feeding ingests the food particles which are suspended in water, while deposit feeding ingests sediments and aquire foods.
What do you mean by Deposit feeders?Deposit feeders may be defined as those aquatic organisms that forage on organic matter that settled down on the bottom.
Suspension feeding maintains the water quality in the aquatic environment, while deposit feeding enhances oxygen level and nutrient cycling.
Suspension feeding occurs similarly to filter-feeding that only ingests suspended particles. While deposit-feeding ingests the deposited particles like detritus, organic matter, etc.

which of the following is needed for cytokinesis in plant cells but not animal cells? (select all that apply!)
a.Actin b.Microtubules c.Kinesin d.Dynein e.Myosin
Actin and Myosin are needed for cytokinesis in plant cells but not animal cells, options a and e are correct.
Cytokinesis, the division of the cytoplasm following nuclear division, differs between plant and animal cells. While animal cells rely on a contractile ring composed of actin and myosin filaments to pinch the cell membrane inward, plant cells have a distinct process due to the presence of a rigid cell wall. In plant cells, cytokinesis involves the formation of a cell plate, which eventually develops into a new cell wall that separates the daughter cells.
This process requires actin filaments for guidance and deposition of materials, as well as myosin to assist in the movement and organization of vesicles involved in cell plate formation. Microtubules, kinesin, and dynein are involved in various cellular processes but are not specifically required for cytokinesis in plant cells, options a and e are correct.

A scientist studying the effects of radiation on DNA performs an experiment in which she exposes a sequence of nitrogen bases found in DNA to radiation. The DNA before and after the radiation is shown below.
Use the evidence to determine whether a mutation has occurred, and if so, interpret that mutation in the answer sheet provided
Before Exposure: ATCGTCA; After Exposure: ATTCGTCA
A. No mutation has occurred to the DNA sequence.
B. A nitrogen base has been deleted from the DNA molecule.
C. A nitrogen base has replaced another nitrogen base in the DNA molecule.
D. A nitrogen base has been added to the DNA molecule.
Answer:
D. A nitrogen base has been added to the DNA molecule.
Explanation:
You can see that the sequence for the nitrogen bases are in the exact same order after the exposure, this rules out A. You can count how many bases there are, 7 before and 8 after so it cannot be B. Lastly, given that they are in the same order as were before and that a base has been added, you can see that no bases were replaced (so not C) and that D is your answer.

according to the perceptual process model what happens immediately after environmental stimuli are received by our sense
The correct answer is: We filter the information through the selective attention process, option d is correct.
After our senses receive environmental stimuli, the perceptual process model suggests that we filter the information through the selective attention process. Selective attention allows us to focus on specific stimuli while filtering out irrelevant or less important information. It helps us allocate our limited cognitive resources efficiently.
When stimuli are received, our sensory systems detect and transmit the signals to the brain. However, our brains are constantly bombarded with a vast amount of sensory information. Therefore, selective attention comes into play to prioritize certain stimuli for further processing. It involves the conscious or unconscious selection of specific sensory inputs, such as sights, sounds, or smells, for further cognitive processing, option d is correct.

of the defense mechanisms proposed by freud, which is exemplified by homophobia?
The Freudian defense mechanism that is exemplified by homophobia is reaction formation.
Reaction formation is a psychoanalytic defense mechanism in which emotions and impulses that are deemed unacceptable or unwanted are unconsciously transformed into their opposite, thus creating a reaction that is often exaggerated and excessive.
According to the psychoanalyst Freud, reaction formation is the act of subconsciously altering your behavior to represent the opposite of what you truly desire. This defense mechanism is frequently used to manage anxiety by altering thoughts, emotions, or behaviors to eliminate unpleasant or undesirable aspects of oneself.

Los insectos polinizadores son especies clave en muchas comunidades que interacción interespecífica se da entre estos insectos??
Answer:
Competencia interespecífica
Explanation:
Los polinizadores son organismos esenciales para el equilibrio de las comunidades silvestres y el mantenimiento de la biodiversidad existente en el planeta. Los insectos (especialmente las abejas) representan el grupo de polinizadores más importantes, estos organismos consumen el néctar como alimento y simultáneamente son utilizados por plantas para reproducirse mediante el trasporte del polen de una flor a otra. Los insectos polinizadores usualmente visitan muchos diferentes tipos de plantas y, a su vez, estas plantas son polinizadas por diferentes grupos de insectos polinizadores. Como consecuencia de esto último, entre polinizadores se establece una competencia interespecífica por un recurso (es decir, el polen) el cual a priori podría considerarse limitado. Sin embargo, ha sido demostrado que las redes e interacciones entre plantas y polinizadores están organizadas de tal modo que la competencia interespecífica entre polinizadores se encuentra reducida drásticamente, siendo incluso beneficiosas para las especies que la componen. Estos resultados se encuentran soportados por el análisis de información a campo la cual demuestra como redes entre polinizadores y plantas son similares en diferentes ecosistemas/continentes y también porque cuando tales conexiones gozan de buena salud se observa un aumento de la biodiversidad en las comunidades ecológicas.

If there is something wrong with the muscular system, the muscles can't perform their function properly while on the other hand, if the digestive system fails to work properly, the metabolism can't happen in our body and our body can be adversely affected.
Compare the Three General patterns of population dispersion
Answer:
Explanation:
There is Uniform dispersion, where the individuals in a population are more or less evenly distributed. Also, there is Random dispersion in which individuals are distributed randomly, meaning there is no plan. Finally, there is Clumped dispersion, where individuals are just distributed in groups. Hope it helps x.
The three general patterns of population dispersion are as follows:
Clumped: Variance/mean is greater than 1.Random: Variance/mean is equal to 1. Spaced: Variance/mean is less than 1. What is Population dispersion?Population dispersion may be characterized as the process of spatial distribution and arrangement at any particular moment of the individuals of a certain species. It generally governs the spacing of individuals with the environment at a given time.
Clumped type is the most common type due to attraction. In a random type, the facts of attraction or repulsion do not favor. Spaced type of population dispersion is also known as uniform.
It is generally present in artificial ecosystems or cultivation. Uniform patterns of dispersion are generally a result of interactions between individuals like competition and territoriality.

In skin, the cells of the epidermis connect to the basal lamina through cellular junctions known as hemidesmosomes. Select the cytoskeletal element that helps maintain the integrity of this connection. intermediate filaments both intermediate microtubules and microfilaments microfilaments only microtubules only
Answer:
The correct answer is ''intermediate filaments.''
Explanation:
The intermediate filaments are made up of thick and resistant protein fibers, with an intermediate thickness between that of the microfilaments and that of the microtubules. They provide mechanical resistance to the cell, avoiding the rupture of the membranes of the cells subjected to stress. The macromolecules that make up the basal lamina interact specifically with specific receptor proteins present in the plasma membrane of the cell base, which in turn interact in the cytoplasm with filaments of the cell cytoskeleton. When the junction is associated with intermediate filaments, it is a hemidesmosome and when it is the actin cytoskeleton that is anchored in the junction, it is focal contacts. Hemidesmosomes are formed by a dense plate attached to the cell membrane, in which the intermediate filaments are inserted by joining connection proteins, such as desmoplakin, which connect to the cytoplasmic portion of the integral proteins of the cell membrane, which belong to the family of integrins.
