The mitral valve is a valve between the left atrium and left ventricle of the heart, consisting of two triangular flaps of tissue that prevents blood from flowing back into the atrium.

Here, correct option is A.

Also, called the bicuspid valve, this valve is located between the left atrium and left ventricle and prevents the backflow of oxygen-rich blood from the left ventricle into the left atrium. The mitral valve is composed of two flaps that open and close in a way similar to a door, allowing blood to flow from the left atrium to the left ventricle, but not back the other way.

The flaps are made of strong connective tissue that is covered in a thin layer of endothelial cells. When the heart contracts, the mitral valve opens and allows oxygen-rich blood to flow from the atrium to the ventricle. When the heart relaxes, the valve closes and prevents the backflow of blood.

The mitral valve is essential for proper functioning of the cardiovascular system, as it ensures that the oxygen-rich blood reaches the ventricle and the rest of the body.

Therefore, correct option is A.

The pharynx is part of two body systems (the respiratory system and the digestive system) because it carries both air and food. At the bottom of the pharynx, two pipes split off — one for air and one for food. One pipe, the larynx, is for air only.

The image shows a nucleotide, which is formed by three parts:

a: a phoshate group

b: a sugar

c: a nitrogenous base (A/U, T, C or G)

In order to prevent rivalry between species and promote coexistence, resource partitioning or niche differentiation (a natural selection process that compels rivals to use resources in different ways) is a strategy.

We utilize ecological modeling to show that a shared mutualist can temporarily partition resource niches by limiting growth rates, even if yield is determined by a resource outside of a mutualism.

A notable illustration of resource partitioning is the anole lizard, which is found on Puerto Rico's island. Natural selection has resulted in the evolution of many species within this group that utilize various resources.

Sheep grazing often causes the increase in the herbaceous vegetation component. This is because sheep tend to preferentially graze on the taller and more nutritious forbs and grasses, leading to a reduction in the abundance of woody plants and shrubs.

This results in an increase in the cover and diversity of herbaceous plants, which can have positive effects on soil fertility and nutrient cycling. Additionally, the increased grazing pressure from sheep can also stimulate the growth and reproduction of herbaceous plants through a process known as defoliation-induced compensatory growth. This occurs when plants respond to grazing by allocating more resources towards shoot growth and reproduction, which can lead to increased seed production and plant density. However, it is important to note that overgrazing can also have negative impacts on the herbaceous vegetation component, such as reducing the abundance and diversity of desirable plant species and increasing soil erosion. Therefore, proper management of grazing pressure and timing is crucial for maintaining healthy and diverse herbaceous vegetation in sheep grazing systems.

The statement "the bond angle in water is smaller than in ammonia because the atomic radius of oxygen is bigger than the one of nitrogen" is true.

The bond angle in water is smaller than in ammonia because of two reasons. Firstly, the atomic radius of oxygen is bigger than the one of nitrogen. This leads to greater repulsion between the lone pairs of electrons on the oxygen atom in water. Secondly, the oxygen atom in water is more electronegative than the nitrogen atom in ammonia, which leads to a stronger bond in water and a smaller bond angle. Therefore, the bond angle in water is smaller than in ammonia.
