Answer 1

Most multicellular organisms execute complex developmental programs that ensure the production of functioning organisms; these developmental programs are heavily dependent on coordinated changes in gene expression.

What is gene expression?

Gene expression refers to the process where the genetic code present in the DNA is used to make a functional product, usually a protein.

Gene expression is important for the production of proteins that are essential to the metabolic activities of the organism.

Gene expression is regulated at various levels in an organism in order to ensure that only proteins required by the body are produced.

The levels of regulation of gene expression include;

believing that dichotomous, or "black-and-white," thinking plays a key role in producing and maintaining dependent personality disorder comes from the _____ perspective.

Answers

According to the cognitive-behavioral perspective, "black-and-white" or dichotomous thinking is a major factor in creating and maintaining dependent personality disorder.

What is personality disorder?

Personality disorder is defined as a form of mental illness when you have an unnaturally inflexible way of thinking, acting, and behaving. It is challenging for someone with a personality disorder to understand and relate to other people. The two personality disorders with the highest prevalence of diagnoses are borderline and antisocial.

According to CBT philosophy, our actions and thoughts have an impact on how we feel. Our ideas, feelings, physical experiences, and behaviors are all intertwined. Numerous studies have demonstrated the efficacy of CBT as a treatment for conditions ranging from pain and insomnia to anxiety and depression.

Thus, according to the cognitive-behavioral perspective, "black-and-white" or dichotomous thinking is a major factor in creating and maintaining dependent personality disorder.

Which two body parts are part of both the digestive and respiratory system?.

Answers

The pharynx joins the throat's larynx and esophagus to the mouth. The epiglottis, often known as the flap-like structure at the end of the pharynx, is there. When eating, the flap moves to one side; when breathing, it moves to the opposite side.

At the back of the nose and mouth, in the pharynx (FAR-inks), or throat, the two airway openings—the nasal cavity and the mouth—meet. Because it carries both food and air, the pharynx is a component of the respiratory system as well as the digestive system. The respiratory system not only aids in breathing but also stops hazardous substances from entering the body when eating, sneezing, or coughing. The pharynx, also known as the throat, is a flexible muscular tube with a funnel-like form that carries air from the mouth and nose to the trachea, also known as the windpipe. It also joins the larynx, esophagus, and nasal and oral canals.

Both the respiratory and digestive systems depend on the pharynx. Air can move from the nasal cavity to the lungs, larynx, and trachea thanks to it. The epiglottis is located in the nasopharynx, a region of the throat. Air is kept out of the digestive system by covering the esophageal opening.

A cell in a multicellular organism receives a signal to increase production of a transmembrane protein found in the cell membrane. Which of the following combinations of structures is expected to be directly involved in the process?

a) Nucleus, chloroplast, cytoskeleton, ribosome
b) Nucleus, ribosome, ER, Golgi complex
c) Lysosome, mitochondria, Golgi complex, cytoskeleton
d) Chloroplasts, nucleus, mitochondria, lysosome

I know that c is wrong, but could someone help explain which is the right one and why c is wrong?

Answers

Answer:

b) Nucleus, ribosome, ER, Golgi complex

Explanation:

"B" is correct because, with protein production, DNA must first be transcripted to RNA in the nucleus, then the RNA travels to a ribosome at the ER to start translation (RNA to amino acid sequence). Finally, it is sent to the Golgi complex to be further processed and/or sorted to be transported to its destination (in this case, it will be sorted to be transported to the cell membrane).

"C" is incorrect: the mitochondria, cytoskeleton, and lysosome do not play a direct role in protein synthesis.

The cytoskeleton is primarily involved with maintaining the structure of the cell along with spindle development in mitosis.The mitochondrion is "the powerhouse of the cell" and is mainly involved with cellular respiration: the process of converting glucose to energy (ATP).Lysosomes' typical function is to break down excess/worn-out organelles and to kill pathogens. Lysosomes have been hypothesized to be part of protein synthesis; however, it has not been confirmed yet.

Why has natural selection favored the evolution of double circulation in birds and mammals?.

Answers

As a result of their higher energy requirements compared to reptiles and amphibians of the same size, natural selection has favored the evolution of double circulation in birds and mammals. The right response in this case is option D.

The rigorous separation of oxygenated and deoxygenated blood is supported by double circulation. In order to ensure that the body always has a dedicated supply of oxygen, this circulation also increases bodily efficiency. In part because of this, mammals are able to regulate their body temperatures.

Blood flows to all four chambers of the heart the left atrium, left ventricle, right atrium, and right ventricle during double circulation. Blood circulation is successfully completed by blood vessels such as the pulmonary artery, aorta, vena cava, and pulmonary vein.

Due to the fact that blood circulates through the heart twice per circuit, it is called a twofold circulation system.

Complete question:

Why has natural selection favored the evolution of double circulation in birds and

mammals?

A - because they have more viscous blood than reptiles and amphibians

Specific cyclins must be expressed to carry out the events of the cell cycle. What is the role of rna polymerase in this process?.

Answers

RNA polymerase is responsible for the synthesis of RNA from DNA template. In order for specific cyclins to be expressed, RNA polymerase must first bind to the promoter region of the gene encoding the cyclin.

Once bound, RNA polymerase will begin to transcribe the gene into RNA. The RNA produced by RNA polymerase can then be translated into protein, which will go on to perform the function of the cyclin. Cyclin is a protein that regulates the cell cycle. It does this by binding to and activating enzymes that control cell division.

Cyclin is produced in response to signals that tell the cell it is time to divide. These signals can come from other cells in the body, or from the environment. Once cyclin is produced, it binds to enzymes that control cell division. These enzymes are called cyclin-dependent kinases (CDKs). CDKs phosphorylate (add a phosphate group to) other proteins that control cell division. This phosphorylation activates these proteins, and the cell begins to divide.

Incomplete dominance and codominance are two different patterns of control that could exist for a single gene with two alleles rather than complete dominance (i.e., other than dominant/recessive).

What are incomplete dominance and codominance?

Incomplete dominance is a genetic phenomenon in which both alleles are expressed in the phenotype in a similar way that the genetic phenomenon of codominance. However, incomplete dominance denoted the higher expression of a gene variant or allele over another, while codominance involves the expression of both alleles in an equivalent manner.

For example, the expression of the A and B alleles in the blood allele system is a case of codominance.
