Blood loss is referred to as bleeding, sometimes known as hemorrhage. It can refer to bleeding that occurs inside the body (internal bleeding) or outside the body (external bleeding).Almost any part of the body can lose blood.When a blood artery or organ is injured, internal bleeding can occur. When there is a rupture in the skin, external bleeding occurs.These three forms of hemorrhage differ from one another in terms of location, flow, and intensity. In particular, capillary bleeding trickles from the body whereas venous blood runs gradually. Arterial bleeding spews out in bursts.

Why evaporation of water is a physical change ?
Evaporation of water is a physical change rather than a chemical change it is because of following ways :
When a liquid evaporates, its chemical composition remains unchanged. The only difference is a phase shift caused by temperature and pressure. As a result, evaporation, or the transition from liquid to gas, is a physical change.
Water evaporation is a physical change because it involves a change in state from a liquid to a gas with no change in the chemical composition of the substance. Water molecules absorb energy in the form of heat during evaporation, which increases their kinetic energy and causes them to move faster. The molecules gain enough energy as they move faster to overcome the intermolecular forces that hold them together as a liquid and escape into the air as water vapour.
Evaporation is a physical change because the water molecules do not change and no new substances are formed. The only thing that changes is the water's state, which changes from liquid to gas. This change in state is caused by the water molecules absorbing energy, which increases their motion and causes them to break free from the liquid phase. As a result, water evaporation is regarded as a physical rather than a chemical change.

to measure primary productivity in a grassland ecosystem, you should _____.
To measure primary productivity in a grassland ecosystem, you should keep customers out; mow, collect, & weigh the plants on a regular basis; and compute plant biomass production every unit time.
Primary productivity is the process by which organisms make their own food from inorganic sources. The majority of primary producers are terrestrial plants and microbial life, such as algae. Primary producers, or autotrophs, are responsible for this phenomenon. Common examples of primary producers include diatoms, dinoflagellates, and coccolithophores.
Net primary productivity varies among ecosystems and depends on many factors. These include solar energy input, temperature and moisture levels, carbon dioxide levels, nutrient availability, and community interactions.
Primary productivity is the amount of biomass or organic matter produced per unit area over a time period by plants during photosynthesis. Biomass can be measured in kilograms, grams or tonnes and area can be measured in meters, inches, hectares or even in kilometers. Primary production typically occurs through photosynthesis; when green plants convert solar energy, carbon dioxide, and water to glucose, and eventually to plant tissue.

c.It reveals differences in the environmental conditions necessary for species survival.
d.it helps in understanding the different behavioral strategies in different individual organisms.
The comparison of the stages of embryological development of different species is a useful tool for biologists to classify life because it helps reveal anatomical similarities that are not always evident in fully formed organisms. Option B is correct.
Biologists use embryological development to study the similarities and differences in the development of various organisms, including their body plans and organ systems.
Embryonic development is the process by which a fertilized egg develops into a fully formed organism, and it is characterized by a series of developmental stages. The comparison of the stages of embryological development between different species can reveal similarities in developmental patterns and structures that are not visible in adult organisms.
