Answer:
The correct answer would be A) many coniferous trees.
Taiga and tundra represent the two coldest biomes of the land on the planet.
The average annual temperature of taiga lies between 41° Fahrenheit and 23° Fahrenheit whereas the temperature of the tundra lies below 23° Fahrenheit throughout the year.
It makes the major difference between the plant life of the two biomes. The taiga is characterized by the presence of coniferous forests which consist of spruces, pines, and larches.
In contrast, vegetation in the tundra is mainly composed of grasses, shrubs, mosses, sedges, and lichens.
Answer:
Option A: True
Explanation:
Insectivorous birds such as bluebirds, dippers and flycatchers prefer to eat medium-sized insects. This is because like most birds, they love easy and satisfying meals. To the birds, a medium-sized insect is a good compromise because it is quite easy to chew and digest and at the same time, easy to find.
As a result, most insectivorous birds prefer to get their daily ration of proteins from the medium-sized birds.
Answer:
o The beavers will not have a suitable habitat available and will gradually decline in number.
Explanation:
According to this question, an earthquake that occurs near a river system weakens a dam wall built by beavers, which are aquatic rodents, and causes the dam to collapse. This initial earthquake will damage the habitat of these aquatic animals (beavers), which is barricaded by the walls built by them around the dam over time.
The walls prevent the constant flow of water but when the walls of the dam collapses, the water in the dam begins to flow excessively i.e floods. This causes the loss of habitat of beavers, hence, resulting in the declination of number
Answer: i- fraternal or dyzygotic twins
ii- monozygotic twins
Explanation: dyzygotic twins develop when two separate oocyte are fertilised by two different spermatozoa. They are also referred to as nonidentical or fraternal twins. They can be of the same or different sex.
Monozygotic twins develop when one oocyte fuses with one spermatozoa and splits into two after fertilization. These twins are also known as identical twins as they will be of the same sex and have the same gene, blood groups and physical features. They may be of different sizes and often have very different personalities and characters.
