HAEMOGLOBIN is able to increase the oxygen-carrying capacity of blood. Due to the fact that each haemoglobin molecule contains 4 haem units, each molecule can BOND to 4 oxygen molecules at once. Hence MUCH more oxygen can be TRANSPORTED around the blood in haemoglobin, rather than being dissolved in plasma.

Floral DIAGRAM is a graphic representation of flower structure. It shows the number of floral ORGANS, their arrangement and FUSION. Different parts of the flower are represented by their respective symbols. Floral diagrams are useful for flower identification or can help in understanding ANGIOSPERM EVOLUTION.

It is sometimes found convenient to describe a FLOWER by a simple and concise for­mula known as the floral formula. In this formula K represents calyx, C=corolla, P= perianth, A=androccium, G=Gynoecium.

Answer:

A sex-determination system is a biological system that determines the development of sexual characteristics in an organism. Most organisms that create their offspring using sexual reproduction have two sexes. Occasionally, there are hermaphrodites in place of one or both sexes. There are also some species that are only one sex due to parthenogenesis, the act of a FEMALE reproducing without fertilization.

In many species, sex determination is genetic: males and females have different alleles or even different genes that specify their sexual morphology. In animals this is often accompanied by chromosomal differences, generally through combinations of XY, ZW, XO, ZO chromosomes, or haplodiploidy. The sexual differentiation is generally triggered by a main gene (a "sex locus"), with a multitude of other genes following in a domino effect.

In other cases, sex of a fetus is determined by environmental variables (such as temperature). The details of some sex-determination systems are not yet fully understood. Hopes for future fetal biological system analysis include complete-reproduction-system initialized signals that can be MEASURED during pregnancies to more accurately determine whether a determined sex of a fetus is male, or female. Such analysis of biological systems could also signal whether the fetus is hermaphrodite, which includes total or partial of both male and female reproduction organs.

Some species such as VARIOUS plants and fish do not have a fixed sex, and instead go through life cycles and change sex based on genetic cues during corresponding life stages of their type. This could be due to environmental factors such as seasons and temperature. Human fetus genitals can sometimes DEVELOP abnormalities during maternal pregnancies due to mutations in the fetuses sex-determinism system, resulting in the fetus becoming intersex.

Answer:

1. paddy crops will be facing obstacles in its growth.

paddy crops are ATTACKED by grasshoppers. there are also other insects and pest which harm paddy crops which are eaten by frogs. if the number of frogs are decreased, the amount of grasshoppers will INCREASE CAUSING harm to the paddy fields.

2 and 3

here the food chain is:

paddy>grasshopper>frog>snake

paddy is the producer and the REST of them are consumers.

if consumer grasshopper increases, the amount of food for the frogs will increase.

so the amount of frogs will also increase due to the abundance.

due to the increase of amount of frogs the amount of food for snakes also increases. so the amount of snakes increases.

as their amounts increase, the increased amounts of snakes eat up the increased amount of frogs. so amount of frogs are decreased. due to this, there is deficiency of snake food. so the amount of snakes also decreases.

similar CASE happens in case of frog a grasshopper

so, eventually the balance of the environment is maintained. this is the overall effect of this ecosystem

hope this helps....
