Answer:
1. Phosphatases hydrolyze key phosphorylated residues.
Explanation:
Receptor Tyrosine Kinases (RTKs) are high-affinity transmembrane protein receptors that bind to a wide variety of ligands (e.g., growth factors, cytokines, hormones). These receptors (RTKs) have a transmembrane domain and therefore these proteins act as membrane receptors, as well as exhibit catalytic activity. The intracellular C terminal region of RTKs contains catalytic domains responsible for both autophosphorylation and tyrosine phosphorylation of their protein substrates. Moreover, Protein Tyrosine Phosphatase (PTPs) are critical enzymes that remove phosphate groups from tyrosine residues in different substrates (including RTKs), thereby regulating key signaling pathways such as cell proliferation, cell differentiation, and cell-cell adhesion.

Hemophilia is an X-linked recessive condition in which blood does not clot properly. Queen Victoria of England had one allele for hemophilia. Most of her male descendants had the disorder, but few females had it. Why did hemophilia occur more frequently in Queen Victoria’s male descendants?
Answer:
Because hemophilia is an X-linked recessive condition.
Explanation:
As the problem states, hemophilia is an X-linked recessive condition.
Meaning that in Queen Victoria's female descendants (coded XX) which inherited the Queen's one allele, for hemophilia to appear in them it would be necessary to inherit another hemophillia-carrying allele from the father.The Queen's male descendants (coded XY) would always manifest hemophilia if they inherited the Queen's hemophilia allele, as they possesed only one X gene.Which toxin is of particular concern for the infected host if antibiotics are used resulting in mass pathogen lysis? Cholera toxin Tetanus toxin Botulinum toxin Endotoxin
Answer: Endotoxin
Explanation:
Antibiotics generally target the cell walls of bacteria with the aim to dissolve it so that the body's immune system can be better able to attack it. When the antibiotics target these cell walls, pathogen lysis occurs and ruptures the cell.
Endotoxins are located in those cell walls and once free, are a source of concern because they can cause an array of medical problems with inflammation being amongst the mildest.

Congestive heart failure (CHF) is an inability of the heart to pump sufficient blood to the body. One sign of CHF is excess fluid in the tissue spaces, known as edema. Describe the location of the edema if the left side of the heart fails, compared to the location of edema if the right side of the heart fails.
Answer:
Explanation:
When the left side of the heart (left ventricle) starts to fail, fluid collects in the lungs (edema). This extra fluid in the lungs (pulmonary congestion) makes it more difficult for the airways to expand as a person inhales. Breathing becomes more difficult and the person may feel short of breath, particularly with activity or when lying down.
When the right side of the heart (right ventricle) starts to fail, fluid begins to collect in the feet and lower legs. Puffy leg swelling (edema) is a sign of right heart failure, especially if the edema is pitting edema. With pitting edema, a finger pressed on the swollen leg leaves an imprint. Non-pitting edema is not caused by heart failure.
Which way do the chlorophyll bands move on the chromatography paper?
Answer:
They move up the chromatography paper.
Because the movement of the chlorophyll bands on the chromatography paper is dependent on the stationary phase and the mobile phase, the pigment separates different colors when moving the top of the paper.
What is the significance of chromatography?Chromatography is a technique that is used to separate and analyze a mixture of chemical substances and is a powerful tool in various fields such as chemistry and biochemistry. The significance of chromatography is that it allows scientists to identify and quantify individual components in a mixture and these techniques are helpful for the synthesis of drugs and other chemical products.

The statement that there must be a preexisting cell in order for a new cell to form is known as cell
Answer:
cells duplicate so when there is no cell it cant make any
Explanation:
The statement that there must be a preexisting cell in order for a new cell to form is known as cell theory.
What is cell theory?The scientific idea that cells make up living organisms, that they are the fundamental structural and organizational unit of all species.
They all originate from previously existing cells is known as cell theory. It was first proposed in the middle of the nineteenth century.
Because cells are the building blocks of all life, cell theory is essential for our understanding of biology.
We can have single-celled organisms like yeasts and bacteria. All living things grow and develop on the basis of cell division, or the division of a cell from one to two to four.
A vital process for life is mitosis. A cell divides into two identical daughter cells after duplicating all of its components, including its chromosomes.
Thus, the statement "cell arises from pre-existing cells" comes from cell theory.

b. processes generate ATP.
c. processes involve electron flow.
d. systems are lodged along and within a membrane surface.
e. all of the above.
Answer:
e. all of the above
Explanation:
Photosynthesis and respiration are two complementary processes.
Photosynthesis occurs in chloroplasts. The electron transport chain is placed in the thylakoid membrane, where it occurs light-dependent reactions.Respiration occurs in mitochondria, in the internal membrane, where is the electron transport chain.Photosynthesis needs solar radiation to produce organic compounds.The respiration process needs organic compounds to obtain chemical energy.Photosynthesis transforms CO₂ into organic compoundsRespiration transforms organic compounds into CO₂.In the photosynthesis process occurs a release of oxygen, which is used during the respiration process. Both processes are part of the carbon biological cycle.Both processes use electron transport chains to capture energy, which will be used in other cellular reactions.Respiration´s final products are CO₂, ATP, and waterPhotosynthesis´s final products of light-dependent reactions are oxygen, ATP, and NADPH.If the lymph system did not do its job, what would be one of the consequences?

which property has not been observed for membrane proteins being degraded for energy during biological pathways
Answer:
energy storage
Explanation:
Membrane proteins are proteins that are either form part of or interact with cell membranes. Based on their interactions, membrane proteins can be categorized into integral proteins, which are a permanent part of a cell membrane, and peripheral proteins, which adhere temporarily to the cell membrane. Membrane proteins play many critical functions, for example, 1-they are involved in the passive and active transport of substances across cell membranes, 2-act as enzymes that catalyze chemical reactions, 3-act as receptors that bind specific molecules (such as hormones or neurotransmitters) in order to activate signaling cascades, 4-mediate communication between cells, 5-provide a mechanical link between the extracellular matrix and the cytoskeleton, etc.

The most common Class II variant is the F508del variant, which is missing the 508th amino acid in the protein but has an otherwise normal sequence. Loss of this amino acid leads to misfolding of the protein, and the misfolded protein is not properly transported to the membrane. Based on this information, how many nucleotides are deleted in the CFTR allele encoding this variant?
Answer:
The correct answer is - 3 (two codons of 507th that are U, C, and the first nucleotide of 508th codon U).
Explanation:
Each amino acid is coded by a three-nucleotide base long codon. So in the case of the F508del variant, there is a deletion of three nucleotides that is encoded for phenylalanine amino acid.
In this isoleucine is encoded by 507th codon that is AUG and 508th codon is UUU codes for Isoleucine.
In this case, two codons of 507th are U, C, and the first nucleotide of 508th codon U. So overall three nucleotides are deleted in the F508del variant..

How does caffeine affect blood pressure?
Caffeine may cause a short, but dramatic increase in your blood pressure, even if you don't have high blood pressure. It's unclear what causes this spike in blood pressure. The blood pressure response to caffeine differs from person to person.
Some researchers believe that caffeine could block a hormone that helps keep your arteries widened. Others think that caffeine causes your adrenal glands to release more adrenaline, which causes your blood pressure to increase.
