Answer:
The Orchids is the diversified structures of flowers, in fact, they have unique feature. Even with the pollination, they have several mechanisms of pollination. Few of them include:
1. Few orchids have self-fertilization where the anther converts from solid-state to a liquid state without any aid of an external pollinating agent.
2. In others, self-pollination occurs, when the caudicles dry the pollen fall on the stigma.
3. This happens through an external pollinator resulting in a diversity of species.
4. This is a very special case where the flower attracts the insect to mate with bright petals, odor, and the shape.
5. These types depend on ants and other insects to get pollinated.
6. Here, the pollens release some kind of force, when an insect gets in contact with anther which results in getting away the agent from the flower.
Answer:
Genetic resistance (or genetic tolerance) refers to the ability of certain organisms to endure environmental conditions that are extremely stressful or lethal to non-adapted individuals of the same species
Explanation:
Answer:
True
Explanation:
Metabolic syndrome as the name implies is a cluster of metabolic related risk factors that increases the risk of cardiovascular disease, although metabolic syndrome can increase the risk of cardiovascular disease, it can also increase the risk of type -2 diabetes mellitus. Examples of thee clusters of risk factors are elevated blood pressure, dyslipidemia etc.
Question 1 The world's population is spread very unevenly. Some spaces are empty or very sparsely populated: we speak of human deserts:
• Cold polar environments are the least populated regions: the ground, frozen permanently, prevents any form of agriculture, the very low temperatures make the habitat difficult.
• The hot or cold desert environments are also not busy: the lack of rain and the strong heat during the day limit the activities of men. The only exceptions are oases.
• The role of relief is more difficult to define. High temperate mountains like the Alps are generally sparsely populated but tropical chains like the Andes have a high population density. However, men have generally settled in the plains, in the valleys (along with the rivers) and on the coasts.
There are also other factors unrelated to land factors that influence population density such as job availability, or even historical factors.
Question 2: Birth rate:
The birth rate (sometimes called the crude birth rate) is the ratio of the annual number of births to the average total population for that year. When the population grows, the contact between people will be more permanent, and it will increase the marriage rate, and thus the birth rate. Age structure:The age structure is a mode of graphical representation of the structure (of age as well as of sex) of a population which constitutes a synthetic image of the past, present and future of the population.When a population resides for a long time in the same place (in favorable conditions, not raising the death rate and without moving), this will vary the age structure by observing an increase in the elderly population.
Answer:
Glucose
Explanation:
Glucose is produced during photosynthesis and it is oxidised during cellular respiration to produce ATP energy.
