What are mutations?
For biology revision
Answer: cells are incredibly accurate when they are copying DNA, but there are going to be some errors.
Most of these errors can often times break the organism in some way or might not at all.
But every now and then, some of these errors either as an individual base pair or maybe cumulatively can produce a different phenotype and potentially a phenotype that has an advantage.
This is mutation.
A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
what are the different types of mutation?There are three types of DNA Mutations:
base substitutionsdeletions insertions.Base substitutions : Point mutations are single nucleotide substitutions; consider the point mutation Glu ——-> Val is the culprit of sickle cell anaemia.
Deletions : A deletion happens when one or more base pairs are deleted from the DNA, which causes a frameshift.
Insertions: Depending on whether multiples of three base pairs are entered, the addition of additional base pairs may cause frameshifts.

How does drinking water affect the kidneys?
Most individuals are aware that our bodies need water to function. Our bodies are actually made up of about 70% water. Water facilitates all bodily processes, whether it be the brain, which directs all bodily movements, the blood, which carries oxygen and nutrients, or even the muscles, which maintain our bones sound and erect. Water is the element that is most essential to human survival, as even our predecessors understood.
Even though they include largely water, other drinks including fruit juice, tea, coffee, and carbonated drinks shouldn't be confused with water. For proper hydration, doctors advise us to consume 13 glasses of water each day. Abdominal discomfort, motion sickness, constipation, diarrhea, and a number of other health problems can result from not drinking enough water. In order to maintain proper body processes, water is essential.

Where is the frog's heart compared to its lungs? How do the locations of these organs affect interactions between the frog's respiratory and circulatory systems?
A frog's heart is situated in the chest, next to the lungs. The frog's heart is connected to a pair of sac-like organs called the lungs, which aid in breathing. Blood that is rich in oxygen is pumped from the lungs to the rest of the body by the heart.
What is anatomy?Anatomy is a branch of biology that focuses on identifying and describing the physical characteristics of living creatures.
A frog's respiratory system has three alternative pathways for oxygen to enter the body: through the skin, the lungs, and an unique mouth lining.
The circulatory system is connected to each of these respiratory surfaces, allowing the blood to be oxygenated.
The heart of a frog is located near to the lungs in the chest. The lungs of the frog are a pair of sac-like organs that help with breathing and are connected to the heart. The heart pumps oxygen-rich blood from the lungs to the rest of the body.

Geologists have observed that a portion of Africa is breaking away from the main continent. This is happening because the African Plate is in the process of splitting up into two parts. Scientists have named the two new tectonic plates the Nubian Plate and Somalian Plate. Both of these plates are not only moving away from each other but also away from the Arabian Plate.
Based on this information, determine the type of boundaries these two new plates would share with each other and the Arabian Plate.
In divergent boundaries, plates separate from each other and new crust is created between them. The boundary these two new plates would share with each other and the Arabian Plate is the divergent boundary.
What are the three types of boundaries?I. Divergent
A new crust is created by the rising molten materials coming from the mantle.
Two plates separate, and a stream of hot material creates a new seabed between them. It occurs in an expansion of the sea bottom.
As old plates get separated, new and young crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates.
II. Convergent.
When two plates move forward to each other, they end up colliding and causing the deformation of one or both plates.
Three possible collisions might occur,
• Two oceanic plates might collide ⇒ subduction
• Two continental plates might collide ⇒ obduction
• Oceanic plate and continental plates collide ⇒ Subduction
III. Transforming.
The plates slide laterally with each other, and they are usually called faults.
It is associated, in general, with the oceanic ridge, although it might also occur on the continental plate.
In the exposed example, the African plate is splitting up into two parts, meaning these two parts are separating from each other. A new seabed is created between the Nubian Plate and Somalian Plate.
Since these plates are also separating from the Arabian Plate, we can also assume a new seabed is emerging between them.
The boundary these two new plates would share with each other and the Arabian Plate is the divergent boundary. Plates are separating from each other. They are not converging nor sliding.

What is the convergent boundary?A convergent boundary (also known as a destructive boundary) is a section of the Earth's surface where two or more lithospheric plates collide. Subduction is the process through which one plate moves beneath the other. The Wadati-Benioff zone, a plane where many earthquakes occur, defines the subduction zone. These collisions occur on timescales ranging from millions to tens of millions of years and can result in volcanism, earthquakes, orogenesis, lithosphere damage, and deformation. Convergent borders occur between the oceanic and continental lithospheres, as well as the oceanic and continental lithospheres.

What is the process that ensures mitral and tricuspid valve closure after the ventricles are filled with blood?
Diastole is the process that ensures mitral and tricuspid valve closure after the ventricles are filled with blood.
Cardiac cycle events can be divided into diastole and systole. Diastole represents ventricular filling, and systole represents ventricular contraction/ejection. Systole and diastole occur in both the right and left heart, though with very different pressures.
Diastole begins with the closing of the aortic valve (or pulmonic) and ends with the closing of the mitral valve (or tricuspid). This period encompasses the ventricular relaxation and filling.
Diastole represents when the blood vessels return blood to the heart in preparation for the next ventricular contraction.

The largest artery is the aorta, the main high-pressure pipeline related to the heart's left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries' shorter branches are called arterioles and capillaries.
What are large lumen veins?Veins bring unoxygenated blood towards the heart, away from tissues at low pressure so the lumen is immense. Blood carries more slower and often against gravity so valves and a larger lumen ensure it is still fascinated efficiently.
