if you eat a candy bar, sugar enters your digestive system. some of that sugar eventually leaves the body through the urinary system. where is the body's last chance to take the sugar and recirculate it into the bloodstream for use by cells before it is excreted as urine?

Answers

Answer 1

Swallowing sugar, food passes through your oesophagus and into your stomach, where it is diluted by digestive juices in preparation for later passage through the rest of your digestive tract.

Sugar and carbohydrate sugars move quickly through your stomach and start to break down in your small intestine. With the aid of digestive enzymes found in the lining of your small intestine, all types of sugar are converted into the tiniest sugar molecules. Once sugar has broken down into a monosaccharide, or single molecule, it is absorbed via the intestine and turned into glucose in your blood. In order to remove blood glucose from your body and distribute it to various cells throughout your body for use as fuel, your pancreas secretes the hormone insulin.

ovulation refers to the ____ during the menstrual cycle.

Answers

Ovulation refers to the release of a matured egg from an ovary during the menstrual cycle. During ovulation, the egg is released from the ovary and travels down the fallopian tube towards the uterus where it may be fertilized by a sperm cell to result in a pregnancy.

This typically occurs around day 14 of a 28-day menstrual cycle, but can vary from woman to woman.Ovulation is triggered by a surge in luteinizing hormone (LH), which is produced by the pituitary gland. This surge occurs about 24-48 hours before ovulation and signals the ovaries to release an egg. The released egg is then available for fertilization for about 12-24 hours. If fertilization does not occur, the egg will disintegrate and be absorbed by the body.Answer: Ovulation refers to the release of a matured egg from an ovary during the menstrual cycle.

what can scientists assume about individuals with similar anatomy

Answers

Analogous and homologous organs make it possible to know the evolutionary history of organisms. Homology concerns ancestry, and analogy concerns convergent evolution.

Homologous bodies

Homologous organs are those that may or may not perform the same function, but have the same basic structure and the same embryonic development. This means, therefore, that individuals who have these organs have shared ancestry.

As an example of homology, we can cite the members of tetrapods. Analyzing the limbs of

AmphibiansReptilesBirds and Mammals,

We noticed that the number and arrangement of bones are quite similar, which shows us the kinship relationship present there. In this case, we have a similar structure, but with different functions, which reflect different lifestyles.

Analogous organs

Analogous organs, in turn, do not reflect ancestral relationships and concern only similar functions. These similarities occur due to convergent evolution, which leads to the emergence of similar characteristics even in individuals from very different groups. This is due to the fact that these characteristics favored survival in similar environments, representing, therefore, adaptations to the environment.

As an example of analogies, we can mention the wings of

Birds and Insects.

These animals have wings that guarantee their flight, however, the structures are quite different. Therefore, the functions are similar, but they do not have the same embryonic origin, nor do they indicate ancestry.

Scientists, when analyzing living beings, have verified, with a certain frequency, structures that make us believe in some common ancestry and in the process of evolution. However, these characteristics do not always reflect the evolutionary relationships between organisms. with this, the theses of analogy and homology were developed.

When during the cardiac cycle is the aortic valve OPEN? a. When it is stimulated by epinephrine from sympathetic postganglionic neurons: b. When it is stimulated by acetylcholine from parasympathetic postganglionic neurons. c. When the pressure in the left ventricle is greater than the pressure in the aorta. d. When the pressure in the aorta is greater than the pressure in the left ventricle

Answers

C) During the cardiac cycle, the aortic valve is open when the pressure in the left ventricle is greater than the pressure in the aorta.

During the cardiac cycle, the opening and closing of the aortic valve are crucial for the efficient functioning of the heart. The main purpose of the aortic valve is to prevent the backflow of blood from the aorta into the left ventricle. It opens when the pressure in the left ventricle exceeds the pressure in the aorta.

When the heart contracts during systole, the left ventricle contracts forcefully, generating high pressure. As a result, the pressure in the left ventricle becomes greater than the pressure in the aorta. This pressure difference causes the aortic valve to open, allowing the oxygenated blood to be ejected from the left ventricle into the aorta and subsequently distributed to the rest of the body.

Once the ventricular contraction ends, and the pressure in the aorta exceeds the pressure in the left ventricle during diastole, the aortic valve closes to prevent the backflow of blood into the heart. This closure ensures that blood continues to flow in one direction, maintaining proper circulation throughout the cardiovascular system.

A child with cystic fibrosis can be born to two parents who do not have the disease, but both have the heterozygous genotype. This is because the disease is caused by having 2 copies of a recessive allele, option B is correct.

Parents who do not have cystic fibrosis but are both carriers of a single copy of the mutated gene are known as heterozygotes. When two heterozygotes have children, there is a 25% chance that their child will inherit two copies of the mutated gene and, therefore, develop cystic fibrosis.

Inheritance of cystic fibrosis follows the principles of Mendelian genetics, where the disease is caused by a recessive allele. If two carriers have children, there is a 25% chance that the child will inherit two copies of the mutated allele, resulting in the disease, a 50% chance of inheriting one normal and one mutated allele, making them a carrier, and a 25% chance of inheriting two copies of the normal allele, option B is correct.

Bacteria express exponential growth models, meaning their population growth is dense-independent and proportional to the population size. In the exposed example, assuming a colony of 114 cells at 3.0 hours, the mutant bacteria will make up 56.14 % of the entire colony.

What is exponential growth?

Exponential growth is one model of population growth together with the logistic growth model.

Populations that experience exponential growth models show an increase in proportion to their size. The increase in the population size depends on the individual's reproduction rate: a population that grows at constant exponential rate gains individuals faster as the population increases in size.

This model states that populations live in an environment with unlimited resource availability, so the density factor does not influence population growth. There is no density-dependence effect nor competition for resources. Natality and mortality rate do not depend on density. There is a constant growth rate per capita, and it is proportional to the population size.

Bacteria usually experience exponential growth.

In the exposed example, we can see that

At 0 hours, there were only one bacteria expressing the new enzymeAfter 1 hour, there were four bacteria expressing the enzymeAfter 2 hours, there were 16 bacteria expressing the enzyme.

We can assume that each bacteria divides every 30 minutes (half an hour). So each bacteria produces 4 new cells every hour.

0 hours ------- 1 bacteria with the enzyme

1 hour --------- 4 bacteria with the enzyme (1 x 4)

2 hours ------- 16 bacteria with the enzyme (4 x 4)

3 hours --------64 bacteria with the enzyme (16 x 4).

Each of the 16 cells present after 2 hours got divided and produced 4 new cells, resulting in 64 cells after 3 hours.

The population growth rate is proportional to the population size.

What is Blood?

Blood is a body fluid in the circulatory system of humans and other vertebrates that delivers necessary substances such as nutrients and oxygen to the cells, and transports metabolic waste products away from those same cells

Blood is composed of blood cells suspended in blood plasma. Plasma, which constitutes 55% of blood fluid, is mostly water (92% by volume), and contains proteins, glucose, mineral ions, hormones, carbon dioxide (plasma being the main medium for excretory product transportation), and blood cells themselves. Albumin is the main protein in plasma, and it functions to regulate the colloidal osmotic pressure of blood.[citation needed] The blood cells are mainly red blood cells (also called RBCs or erythrocytes), white blood cells (also called WBCs or leukocytes) and platelets (also called thrombocytes). The most abundant cells in vertebrate blood are red blood cells. These contain hemoglobin, an iron-containing protein, which facilitates oxygen transport by reversibly binding to this respiratory gas thereby increasing its solubility in blood.In contrast, carbon dioxide is mostly transported extracellularly as bicarbonate ion transported in plasma.

Vertebrate blood is bright red when its hemoglobin is oxygenated and dark red when it is deoxygenated.

Some animals, such as crustaceans and mollusks, use hemocyanin to carry oxygen, instead of hemoglobin.Insects and some mollusks use a fluid called hemolymph instead of blood, the difference being that hemolymph is not contained in a closed circulatory system. In most insects, this "blood" does not contain oxygen-carrying molecules such as hemoglobin because their bodies are small enough for their tracheal system to suffice for supplying oxygen.

according to the fluid mosaic model,plasma membrane are mainly composed of phospholipids and proteins.Explain how structures S and T play the roles in the plasma membrane,which function as a selective barrier. please help me with this question ​

according to the fluid mosaic model,plasma membrane are mainly composed of phospholipids and proteins.Explain

Answers

Answer:

The plasma membrane is a thin layer of lipid molecules that surrounds the cell and separates the inside from the outside. The fluid mosaic model describes the structure of the plasma membrane as a two-layered structure of phospholipids with embedded proteins. This model explains how the structure of the plasma membrane allows it to act as a selective barrier, regulating the movement of substances in and out of the cell.

Structure S in the plasma membrane is represented by the phospholipids, which form a lipid bilayer with hydrophilic heads facing outwards and hydrophobic tails facing inwards. The hydrophilic heads are in contact with the extracellular fluid and intracellular fluid while the hydrophobic tails are in the middle of the membrane. The phospholipid bilayer provides a barrier that separates the inside and outside of the cell, restricting the movement of hydrophilic and large molecules through the membrane while allowing the passage of small and hydrophobic molecules.

Structure T represents the integral membrane proteins that are embedded in the lipid bilayer. These proteins have different functions, such as transport of molecules, cell signaling, and catalyzing chemical reactions. The proteins also contribute to the selective permeability of the membrane by regulating the movement of specific molecules in and out of the cell. For example, channels and carrier proteins regulate the movement of ions and larger molecules through the membrane while receptor proteins receive signals from the outside of the cell and relay them to the inside of the cell.

In summary, the plasma membrane is mainly composed of phospholipids and proteins according to the fluid mosaic model. The phospholipids form a lipid bilayer that acts as a barrier, while the proteins embedded in the bilayer regulate the selective permeability of the membrane by facilitating the movement of specific molecules in and out of the cell.

List the seven major fish body forms. For three of the seven body forms, briefly
describe how physical characteristics are related to the habitat and niche of fish
species in that category.

Answers

The seven major fish body forms are- fusiform, compressiform, anguilliform, filiform, depressiform, sagittiform, and globiform.

Below are the descriptions of the three body forms and how their physical characteristics are related to their  habitat and niches:Fusiform body form: This body form has a streamlined shape that allows for easy movement through the water. It is most commonly found in open-water fish, such as tuna and mackerel, that need to move quickly to catch prey and avoid predators. Its narrow shape reduces drag, which increases its swimming speed. The fusiform body form is particularly adapted for fast swimming, and it is typically found in fish that are pelagic (live in open water).

Compressiform body form: This body form is flattened from side to side, which gives the fish a ribbon-like appearance. The compressiform body form is well adapted to moving through the water by means of quick, darting movements. They are generally found in areas of shallow water or near the bottom of the sea floor, where they can quickly move to escape danger. For example, eels use the compressiform body form to move quickly through small crevices.Anguilliform body form: This body form is characterized by a long, thin shape that allows the fish to easily move through the water.

This body form is found in fish like eels, which live in narrow spaces such as burrows, rock crevices, or coral reefs.
