So they know for sure their answer is correct before they move on.
Answer: They're all organisms, and are composed of eukaryote cells.
Explanation:
Sorry if this doesn't help, but there's no answer choices :P
For example:
If both parents are with heterozygous genotype Aa (A is dominant allele for the trait and a is recessive allele for the trait) , than
P: Aa x Aa, the offspring will be
F1: AA Aa Aa aa (one dominant homozygous, one recessive homozygous and two heterozygous.
Climate is defined as the weather condition that is measured over a time period of 30 years for a particular region and for a period of time. Climate of a region depends upon several factors such as pattern of temperature, rate of precipitation, humidity, wind direction and seasons. Various types of instruments are used to determine the climatic condition of a particular region as it depends on several factors, these instruments are:
Barometer is used to measure the atmospheric pressure of the region.
Wind Vane is used to show the direction of the wind.
Rain Gauge is used to measure the amount of precipitation over a period of time.
Snow gauge is used to measure solid precipitation
Hygrometer is used to measure the relative humidity.
Answer:
They tunnel through the soil, which allows air to enter.
Explanation:
Earthworms are considered to be agriculturally friendly living organisms that hold immense importance in improving the growth and productivity of plants.
They live in the soil and feed on the debris of plants such as manure, grasses, roots and dead leaves. They extensively channel and tunnel through soils while moving that causes loosening of the soil resulting in more aeration of the soil. The more the soil aeration is, the better soil drainage is.
Studies have shown that soil containing earthworms have ten times better drainage than soils that donot have earthworms. Therefore, C is the best option.
Hope it help!
