Answer:
Crossing over occurs in meiosis but not in mitosis
Explanation:
Miosis is a process in which diploid cell becomes a haploid cell.which is essential for sexual reproduction In mitosis the daughter cells are identical whereas in meiosis the daughter cells are different due to crossing over.the process of crossing over does not occur in mitosis.
Answer:
Cytokinesis is a phase in which two daughter cells are separated from one another.
Explanation:
Cytokinesis is a phase in which cytoplasm of the cell is divided into two equal parts after the cell division i. e. mitosis or meiosis. Cytoplasm is a main part of the cell which contains different organelles of the cell such as mitochondria, ribosome, endoplasmic reticulum, golgi bodies, lysosomes and vacuole etc. It also contains nutrients, enzymes and water in large amount.
Answer:
The correct answer is - roundworms.
Explanation:
The answer is already mention in the question, however, the detailed answer is as follows:
The characteristics that are given in the question are true tissues, bilateral symmetry, and a pseudocoelom. Worms or helminths are known as primitive form of organization of the Bilaterians. All three group of worms or helmints have a basic bilateral symmetry.
These organisms inaugurated various characteristic that are found and carried by other animals such as true tissues, bilateral symmetry, and a pseudocoelom.
Thus, the correct answer is - roundworms.
A cycadophyta is a biological dividsion, and within this,nthree are three families, and these are; Cycaclaceae, Strangeriaceae and Zamiceae. The plants of these are seed plants, which generally have characteristics, such as a stout, short and tough trunk made of wood, with a crown like span of evergreen leaves, with a cone shape protruding from the centre of the tree.
Sorry, I wasnt able to attach an image, but if you google cycadophyta, this is what they look like.
Sorry for the inconvenience, hope this helps
<span>All are mutagenic because they cause base substitutions, deaminating agents oxidatively deaminate bases so cytosine converted to uracil and adenine converted to hypoxanthine, uracil pairs with adenine and hypoxanthine pairs with cytosine, alkylating agents donate alkyl group to amino or keto groups altering base pair affinities</span>
