Answer:
The correct answer would be meiosis.
In diploid organisms, meiosis is the process that results in the formation of four haploid daughter cells from single diploid parent cell. Each of the daughter cell contains half the number of chromosomes present in parent cell.
It results in the formation of haploid gametes (sperm in males and eggs in females) which is essential in the process of sexual reproduction.
The fusion of gametes results in the formation of diploid zygote that is, maintains the diploid nature of the organism.
Hence, in absence of meiotic division the chromosomal number would keep on doubling after each generation.
In addition, crossing over (exchange of genetic material between non-sister chromatids) also takes in the prophase-I of meiosis I. It increases the genetic variation within organisms of the species. It may add survival adaptations to the population.
rectas paralelas: dos rectas son paralelas cuando no llegan a tener ningún punto en común por más que se. rectas oblicuas: dos rectas son oblicuas cuando al cortarse no son pendiculares es decir no forman cuatro ángulos iguales.
The answer is B. Morphogenesis
Answer:
To predict the results of the offspring from a cross between brown heterozygous rabbit and a white homozygous rabbit, a punnet square can be drawn as follows:
b b
B Bb Bb
b bb bb
The results from the punnet square show that there is 2:2 ratio that the offspring will be brown coloured or white coloured. The genotype of the rabbits will either be heterozygous brown i.e Bb or homozygous white bb.
there is a 50% chance that the offspring will be brown rabbit and there is also a 50% chance that the offspring can be a white rabbit.
Answer:
Hypothesis
Hypothesis 1:Caffeine is a stimulant and will result in an increase in the typing speed of the participants.
Hypothesis 2:Caffeine is a stimulant and will result in a decrease in typing accuracy.
Hypothesis 3:The heart rate of the people will increase with the intake of caffeine.
Aim of the study
The aim of this study is to determine the following:
• The effect of caffeine on typing speed
• The effect of caffeine on typing and accuracy.
• The effect of caffeine on the heart rate of people.
