Answer:
Give me answer choices then I can help you
Explanation:
Answer:
examination of data from a number of independent studies of the same subject, in order to determine overall trends.
mv^2 =2* e*40k J/Cv= sqrt(2* e*40k/m)
mv^2/r = F centripetal = evB2* e*40k/(210*sqrt(2* e*40k/m)*e) =BB=√e∗80,000∗m−−−−−−−−−−−/210
The cell cycle is the period of time from the beginning of one cell division to the beginning of the next.
The cell cycle is the series of biological events which cells go through as they grow and divide. The cell cycle has two phases.
(i) Mitosis
(ii) Interphase.
Interphase is broken down to G1 which is growth phase, S which is Dna synthesis phase and G2 which is growth phase again. In Mitosis it consists of anaphase, telophase, prophase, and metaphase.
The cell cycle begins in cytokinesis and ends in Mitosis. Mitosis cannot start before interphase ends because mitosis requires a lot of energy and nutrients to go through the process.Since interphase is the beginning of G1,Dna synthesis and G2 comes to play, it helps to create nutrients and energy.
Let’s have an example of a menstrual cycle. You bleed at the beginning of a cycle not at the end. The first day of your period is the menstrual cycle.
Answer:
three evolutionary lines
Explanation:
The Hox genes are master developmental genes found in animals, which are involved in the regulation of development by specifying the body plan of an embryo along the head-tail axis. Recently, several research groups studied the assortment of the Hox genes in three different marine organisms: 1- a priapulid worm (an unsegmented marine worm), 2- a brachiopod (phylum Brachiopoda), and 3- a polychaete worm (related to earthworms). Then, these research groups combined their research efforts to compare the assortment of the Hox genes observed in these species to those observed in previously studied animals including, among others, mice, fruit flies and sea urchins. From this combined study, researchers concluded that the animal kingdom can be divided into three primary evolutionary lineages.
