If a freely floating ship has a weight of 5*10^5N, what will be the weight of water displaced by the ship?

Answer:

1. merkel cells

2. tactile corpuscle

3. lamellated (lamellar) corpuscle

4. nociceptors

Explanation:

Merkel cells are epithelial cells found around hair follicles which are capable of sensing gentle touch sensations such as, for example, tactile discrimination and environmental exploration. Tactile corpuscles are a class of nerve ending required for mediating sensitivity to light touch sensations. The lamellar corpuscles are another class of nerve ending capable of sensing deep touch sensations and vibrations. Finally, nociceptors are somatic sensory receptors capable of sensing noxious (damaging) stimuli.

1. Light-touch receptor located at the epidermal-dermal border: Tactile corpuscles (D)

Light-touch sensors called tactile corpuscles, sometimes referred to as Meissner's corpuscles, are situated near the epidermal-dermal boundary. They are located in the papillary layer of the dermis's dermal papillae, which are tiny, finger-like projections.

Particularly dense populations of tactile corpuscles can be seen in skin regions like the lips, palms, and fingertips that are sensitive to gentle touch.

2. Light-pressure receptor located in the papillary layer of the dermis: Merkel cells (A)

3. Deep pressure receptors: Lamellated corpuscle (C)

4. Receptors that respond primarily to pain and temperature: Nociceptors (B)

If someone is bleeding severely, the body's adaptive response is to increase sympathetic stimulation of the kidney and therefore decrease GFR. The correct answer is option c.

When someone is bleeding severely, the body activates the sympathetic nervous system in response to the decrease in blood volume and pressure. This activation leads to vasoconstriction of the blood vessels, including those in the kidneys. This constriction reduces the blood flow to the kidneys and therefore decreases the glomerular filtration rate (GFR), which is the rate at which blood is filtered through the kidneys.

This mechanism helps to maintain blood pressure and prevent further blood loss by redirecting blood to vital organs such as the brain and heart. In contrast, if sympathetic stimulation of the kidney were decreased, this would lead to an increase in GFR, which could exacerbate the bleeding and decrease blood pressure even further.

Therefore, option c is the correct answer.

Answer:

Mushrooms are the advanced members of a fungi group belonging to the class Basidiomycetes. They grow on dead and decaying matters like dung, and old rotten logs which are rich in organic matter. Therefore, they are saprophytic fungi.

The resistance is highest in the smaller conducting airways, specifically in the bronchioles, which are the smallest airways in the lungs.

The bronchioles are lined with smooth muscle, which can constrict or relax to adjust airflow resistance. When the smooth muscle contracts, the airway diameter decreases, and the resistance to airflow increases. This is known as bronchoconstriction, which can occur in response to various stimuli such as allergens, irritants, and exercise.

Additionally, the bronchioles lack cartilage support, which makes them more prone to collapse under negative pressure. Therefore, given that the resistance varies in Mike's conducting airways, the highest resistance is likely to be in his bronchioles, which are the smallest airways with smooth muscle and lack of cartilage support.

Answer:

DNA is a dynamic and adaptable molecule. As such, the nucleotide sequences found within it are subject to change as the result of a phenomenon called mutation. Depending on how a particular mutation modifies an organism's genetic makeup, it can prove harmless, helpful, or even hurtful. Sometimes, a mutation may even cause dramatic changes in the physiology of an affected organism. Of course, in order to better understand the varying effects of mutations, it is first necessary to understand what mutations are and how they occur.

Where do mutations occur?

Mutations can be grouped into two main categories based on where they occur: somatic mutations and germ-line mutations. Somatic mutations take place in non-reproductive cells. Many kinds of somatic mutations have no obvious effect on an organism, because genetically normal body cells are able to compensate for the mutated cells. Nonetheless, certain other mutations can greatly impact the life and function of an organism. For example, somatic mutations that affect cell division (particularly those that allow cells to divide uncontrollably) are the basis for many forms of cancer.

Germ-line mutations occur in gametes or in cells that eventually produce gametes. In contrast with somatic mutations, germ-line mutations are passed on to an organism's progeny. As a result, future generations of organisms will carry the mutation in all of their cells (both somatic and germ-line).

What kinds of mutations exist?

Mutations aren't just grouped according to where they occur — frequently, they are also categorized by the length of the nucleotide sequences they affect. Changes to short stretches of nucleotides are called gene-level mutations, because these mutations affect the specific genes that provide instructions for various functional molecules, including proteins. Changes in these molecules can have an impact on any number of an organism's physical characteristics. As opposed to gene-level mutations, mutations that alter longer stretches of DNA (ranging from multiple genes up to entire chromosomes) are called chromosomal mutations. These mutations often have serious consequences for affected organisms. Because gene-level mutations are more common than chromosomal mutations, the following sections focus on these smaller alterations to the normal genetic sequence.

Base substitutions are the simplest type of gene-level mutation, and they involve the swapping of one nucleotide for another during DNA replication. For example, during replication, a thymine nucleotide might be inserted in place of a guanine nucleotide. With base substitution mutations, only a single nucleotide within a gene sequence is changed, so only one codon is affected.

Although a base substitution alters only a single codon in a gene, it can still have a significant impact on protein production. In fact, depending on the nature of the codon change, base substitutions can lead to three different subcategories of mutations. The first of these subcategories consists of missense mutations, in which the altered codon leads to insertion of an incorrect amino acid into a protein molecule during translation; the second consists of nonsense mutations, in which the altered codon prematurely terminates synthesis of a protein molecule; and the third consists of silent mutations, in which the altered codon codes for the same amino acid as the unaltered codon.

La degradación de carbohidratos, sobre todo de la glucosa, es la fuente principal de energía en la célula. La degradación oxidativa de la glucosa a CO₂ y H₂O produce una gran cantidad de energía libre, la cual puede almacenarse en la célula en compuestos ricos en energía como el ATP.

La glicólisis es la etapa principal en la degradación de la glucosa, la cual se oxida hasta piruvato. Ocurre en ausencia de oxígeno y por lo tal organismos anaerobios utilizan este mecanismo para obtener energía. Durante este proceso se obtienen 2 moléculas de ATP.

Luego, el piruvato se oxida para dar un acetilo, que se une a una Coenzima A dando acetil-CoA. Luego éste entra en el ciclo de Krebs, que es la vía central del metabolismo oxidativo. El acetilo se combina con oxalacetato para dar citrato. A través de ocho reacciones dos carbonos se oxidan completamente a CO₂ y se regenera el oxalacetato. Durante el ciclo se genera GTP, un compuesto con un enlace de alta energía. Además, cada vuelta del ciclo produce tres moléculas de NADH y una de FADH₂, que son transportadores de electrones.

Durante la fosforilación oxidativa, los electrones de estos transportadores se combinan con oxígeno y la energía liberada en el proceso promueve la síntesis de ATP.

Answer:The respiratory system is the network of organs and tissues that help you breathe. It includes your airways, lungs and blood vessels. The muscles that power your lungs are also part of the respiratory system.

Explanation:

True. Steroid hormones are lipid-soluble and can easily cross the plasma membrane of cells.

Once inside the cell, they bind to specific receptors located in the cytoplasm or nucleus, forming a hormone-receptor complex that then binds to DNA and modulates gene expression. This can result in the activation of specific genes that lead to the cellular response, which in this case, is an increase in RNA synthesis. The increase in RNA synthesis is a result of the activation of genes that encode for RNA polymerases, enzymes that catalyze the synthesis of RNA molecules. Other hormones, such as peptide hormones, cannot directly affect gene expression as they cannot cross the plasma membrane and require specific receptors on the cell surface to exert their effects. Therefore, if the cellular response to a hormone caused an increase in RNA synthesis, the hormone most likely was a steroid hormone.

The four parts of the DNA strand are hydrogen bonds, nitrogenous bases, a phosphate group and a pentose sugar.

The double helical structure of DNA is composed of nucleotides held by phosphodiester linkages. Each nuceotide in DNA is composed of a pentose sugar called deoxyribose, four nitrogenous bases -adenine, cytosine, guanine, and thymine, and a phosphate group. The nitrogenous bases in DNA molecules are held by hydrogen bonds. The double strands of the DNA molecule are twisted around each other on a common axis to form a helix that closely resembles a ladder.

The pairing of bases is said to be complementary in nature. This means that adenine is paired with thymine by double hydrogen bonds, and guanine is paired with cytosine by triple hydrogen bonds. This complementary pairing of nitrogenous bases is in accordance with the Chargaff's rule.

The statement people taking two or more drugs at the same time are more vulnerable to nutrient-drug interactions is true because multiple drugs can affect the absorption, metabolism, and excretion of nutrients, leading to potential interactions.

When individuals take multiple drugs concurrently, there is an increased likelihood of nutrient-drug interactions. Different medications can interfere with the body's ability to absorb, metabolize, or excrete nutrients, potentially leading to imbalances or deficiencies.

Certain drugs can inhibit the absorption of specific nutrients, impairing their uptake by the body. For example, some medications used to lower cholesterol levels can reduce the absorption of fat-soluble vitamins like vitamin D, E, and K. Similarly, certain antibiotics can interfere with the absorption of minerals like calcium, iron, and magnesium.

Additionally, drug metabolism can be influenced by various nutrients. Some medications rely on specific enzymes for their breakdown, which can be affected by nutrient levels. For instance, grapefruit juice can inhibit the activity of certain liver enzymes responsible for drug metabolism, leading to increased drug concentrations in the body.

Furthermore, some drugs can impact nutrient excretion through the kidneys. Diuretic medications, for example, increase urine production, potentially resulting in the loss of water-soluble vitamins like vitamin C and B vitamins.
