of the 7,000 to 8,000 people bitten annually by venomous snakes, ________ will die.

Answers

Of the 7,000 to 8,000 people bitten annually by venomous snake, approximately 5 to 10% will die. This means that between 350 and 800 people will die from venomous snake bites each year.

The actual number of fatalities may differ based on a variety of variables, such as the type of snake, the dosage of venom, and the level of medical attention.

Cobras and vipers are two venomous snake species that are more likely than others to be lethal. A higher risk of death is typically connected with bites from larger and more deadly snakes.

The species of snake and the amount of venom injected affect how severe the symptoms are as well. In addition to pain and swelling, venomous snake bites can cause nausea, vomiting, respiratory difficulties, and even paralysis.

To reduce the risk of fatal complications and major complications, prompt medical attention is crucial. Antivenom, painkillers, and supportive care like hydration may all be used in the course of treatment.

A. produces vitamin D and other chemical needed by the kidney
B. is necessary as a barrier between the adrenal glands and kidneys
C. stabilizes th position of the kidnes by holding them in their normal position
D. ensures adequate energy for the adrenal glands to operate efficiently

Answers

The fatty tissue surrounding the kidneys is important because stabilizes the position of the kidneys by holding them in their normal position so the correct answer is option (c).

The fatty tissue surrounding the kidneys is important because it stabilizes the position of the kidneys by holding them in their normal position.The kidneys are essential organs in our bodies that help to remove waste products and excess fluids from the bloodstream. They also help to balance the levels of salt, potassium, and other electrolytes in the body. They are located in the lower back, on either side of the spine, and are surrounded by a layer of fatty tissue.

This fatty tissue serves to protect the kidneys from injury, and also helps to keep them in their normal position. Without this fatty tissue, the kidneys would be more vulnerable to injury and would be more likely to move out of their normal position.

In summary, the fatty tissue surrounding the kidneys is important because it stabilizes the position of the kidneys by holding them in their normal position.

it is possible for two different genes to imply different phylogenetic relationships among a group of species. what are the possible reasons for this? i

Answers

Different phylogenetic trees reconstructed from different genes in the same organism can have different branches. The potential causes of such differences have been identified, and they range from methodological issues to genuine biological phenomena.

It's difficult to visualize phylogenetic relationships between species based on numerical values from multiple pairwise comparisons, especially when many different sequences are compared. A phylogenetic tree built on identity values is another way to visualize phylogenetic relationships. Calculations for phylogenetic tree construction can be done in two ways: using a distance matrix or using discrete character data (Table 11.2). Data based on evolutionary distances are set in a distance matrix in the first calculation. Most calculation methods do not assign equal weight to each nucleotide mutation. The DNA structure is crucial in the calculations.

You cannot see single atoms without a special microscope. But every substance around you is made of atoms.

Explanation:

Atoms make up every substance around you is the true statement. Therefore, option (D) is correct.

What are atoms?

An atom is the smallest unit of matter that retains all of the chemical properties of an element. Atoms combine to form molecules, which then interact to form solids, gases, or liquids.

Moreover, at the most basic level, all organisms are made of a combination of elements. They contain atoms that combine together to form molecules. In multicellular organisms, such as animals, molecules can interact to form cells that combine to form tissues, which make up organs.

Every day, our bodies take in new atoms from the air we breathe, the food we eat, and the liquids we drink. These atoms are incorporated into our cells and fuel the chemical processes that keep us alive.

Explain the Frank-Starling law of the heart.
Make sure to give a short, explanation of the Frank-Starling law and the role of stretch on
the cardiac contractile tissue has on the force of contraction. You should then explain
how this property allows for the matching of venous return and stroke volume. Some
important topics to consider as you answer this question are end-diastolic-volume (EDV),
end-systolic-volume (ESV), venous return, preload, afterload, and Starling curves.

Answers

The Frank-Starling law of the heart states that the force of contraction of the cardiac muscle is directly related to the initial length or stretch of the muscle fibers. In simpler terms, when the cardiac muscle is stretched, it contracts more forcefully.

The cardiac muscle fibers have an inherent property that enables them to generate greater force when they are stretched. This property is due to the increased overlap of actin and myosin filaments within the muscle fibers when they are elongated. When the muscle fibers are stretched, the actin and myosin filaments have a more optimal arrangement, allowing for stronger and more efficient muscle contractions.

Now, let's discuss how the Frank-Starling law allows for the matching of venous return and stroke volume. The stroke volume refers to the amount of blood pumped out of the heart with each heartbeat, while venous return refers to the amount of blood flowing back to the heart from the veins.

According to the Frank-Starling law, the initial length or stretch of the cardiac muscle fibers, known as the end-diastolic volume (EDV), determines the force of contraction. When there is an increase in venous return, more blood fills the heart during diastole, leading to an increase in the EDV. This increased volume stretches the muscle fibers of the heart.

The stretched muscle fibers, in turn, generate a more forceful contraction during systole, leading to a larger stroke volume. This increased stroke volume effectively matches the increased venous return, maintaining the balance between the amount of blood entering the heart and the amount of blood pumped out.

It's important to note that the Frank-Starling law is influenced by two other factors: preload and afterload. Preload refers to the degree of stretch of the cardiac muscle fibers before contraction, primarily determined by the volume of blood in the ventricles at the end of diastole. Afterload, on the other hand, refers to the resistance the heart must overcome to eject blood during systole, usually represented by the pressure in the aorta.

The relationship between preload, afterload, and stroke volume is depicted by the Starling curves. These curves illustrate how changes in preload (EDV) can affect stroke volume. When preload increases, the Starling curve shifts upward, indicating an increase in stroke volume. However, if afterload increases (such as in conditions like hypertension), the curve shifts downward, reducing the stroke volume.

For fruits/vegetables, why do some sugars exist in simple forms and some sugars in complex forms?

Answers

Simple sugars are a type of carbohydrate. Carbohydrates are one of the three basic macronutrients — the other two being protein and fat.

Simple sugars are found naturally in fruits and milk, or they can be produced commercially and added to foods to sweeten, prevent spoilage, or improve structure and texture.

Monosaccharides are the simplest carbs, in that your body cannot break them down further.

This allows your body to absorb them quickly and easily, with the exception of fructose.

There are three types of monosaccharides (1Trusted Source):

Glucose: Fruits and vegetables are natural sources of glucose. It’s also commonly found in syrups, candy, honey, sports drinks, and desserts.

Fructose: The primary natural dietary source of fructose is fruit, which is why fructose is commonly referred to as fruit sugar.

Galactose: The main dietary source of galactose is lactose, the sugar in milk and milk products, such as cheese, butter, and yogurt.
