Answer:
mutations
Explanation:
mutations are errors in codons caused by changes in nucleotide bases.
Nitrogen is an essential nutrient for plant growth. But farmers who cultivate pulse crops like green gram, bengal gram,black gram, etc. do not apply nitrogenous fertilizers during cultivation because of following reason
1. Leguminous plants like green gram, bengal gram,black gram contain nitrogen fixing RHIZOBIUM bacteria which convert nitrogen gas of air into nitrogen compounds which can be used by plants for their compounds
2. The nitrogen fixing Rhizohium bacteria live in the root nodules of leguminous plants.
Answer:
During fertilization, two gametes from the parents —with different genetic information— join together to obtain a unique offspring, different from the parental cells that gave rise to it.
Explanation:
Gametes are the cells produced by each individual to transmit their genetic information to their offspring.
The process of producing gametes is called gametogenesis, and it is a reductive division called meisois. During meiotic division, crossing over occurs, allowing the recombination of genes, which results in genetic variability.
What makes the offspring different and unique from the parental generation is that, during fertilization, the genetic characteristics of both parents are mixed when two gametes are joined.
Answer:
Most protists have mitochondria and chloroplasts. This is statement is true.
Explanation:
Protists are the organisms that are eukaryotes i. e. have true nucleus and made of single cell. Most of the protists contain chloroplast. These protists are green in color due to the presence of chlorophyll that's why they make their own food like plants. Some protists also contains mitochondria which generates energy from the food they eat.
Trilateration Measures Distance, Not Angles
Using a simple two-dimensional example, let's imagine we have three GPS satellites each with a known position in space. ... This means that the distance could be anywhere on that circle. But this time, we have two known distances from two satellites.
