Answer:
The correct answer is D: diploid phase
Explanation:
The essence of plant life is their characteristic property of alternation of generations. Each plant undergoes alternation of generations and produces haploid and diploid generations.
This property allows the plant to reproduce both sexually and asexually. Primitive plant species used to reproduce through spores and spent the majority of their life as haploid cells. These cells were called as spores and required only matter and energy to reproduce.
Modern plant species reproduce by using gametes and spent the majority of their life in diploid phase called diploid sporophytes.
The lipid components of cellular membranes often include phospholipids and cholesterol. Phospholipids is made up of glycerol, fatty acids, phosphate and organic derivatives such phospho inositol and choline. Cholesterol is the component of the membrane lipid which determine the fluidity of the memebrane; it also participates in membrane singalling system.
The nurse should assess the patient vital sign and notify the healthcare provider. For 2.5 hour after neck dissection, production of 40ml by the drainage is a bit excessive. There might be a bleeding in the site of operation that becomes the source of the drainage. Change dressing will not do anything. Applying pressure can be done if the site of bleeding is known.
1. The phrase Darwin used to describe his broad theory of evolution is ''descent with modification.
2. All of life is related through common ancestry, accounting for the Unity.
Answer:
B. there were more double crossovers in the progeny than would be expected based on probability
Explanation:
Crossing over or recombination can be defined as the exchange of genetic material between homologous chromosomes during meiosis. Moreover, the coefficient of coincidence is the number of double recombinants found in the progeny. The coefficient of coincidence can be estimated by the following equation:
Coefficient of coincidence (COC) = ADRF / EDRF
where ADRF = Actual Double Recombinant Frequency
and EDRF = Expected Double Recombinant Frequency
In the case above described, ADFR is higher than EDRF, and therefore COC will be higher than 1.
