Answer:
3/16
Explanation:
Two true-breeding stocks of pea plants are crossed. One parent has red RR, axial flowers AA and the other has white rr, terminal flowers aa
Parent cross RRAA x rraa
Gamete: RA x ra
F1 gen. RrAa
Selfing of F1. RrAa x RrAa
F2 offspring
Rr x Rr Aa x Aa
RR Rr rr AA Aa aa
3/4 red 1/4 white 3/4 axial 1/4terminal
Probability of plants with white axial flowers is 1/4*3/4 = 3/16
Answer:
a. a plant cell undergoing cytokinesis
Explanation:
Cytokinesis is the process where the cytoplasm divides after mitosis to form two different daughter cells from the parent cell. Animal cell divides by just a cleavage formation. Plant cells have an additional step of formation of cell plate because they have cell wall.
At the end of anaphase and beginning of telophase when the two new daughter nuclei have just formed, cell plat formation begins. Secretory vesicles from golgi body come at equator of the dividing parent cell. These vesicles release all the materials required for cell wall formation. The materials start to form the cell plate which moves outwards till it reaches the division site of parent cell wall. Slowly cell wall arises from cell plate and cytokinesis occurs giving rise to new plant cells.
Answer;
Bedrest with bathroom privileges
Explanation;
-Cardiac catheterization is a procedure used to diagnose and treat cardiovascular conditions. During cardiac catheterization, a long thin tube called a catheter is inserted in an artery or vein in the groin, neck or arm and threaded through the blood vessels to your heart.
-A child should not have a tub bath or go swimming for 5 days after the catheterization. After a child goes home from the hospital, they should be able to eat normally.
Answer:
Explanation:
DNA are the building blocks of chromosome. Think about a blueprint. Blueprint contain instructions of how to build something, the actual instructions are the drawing and those drawings are housed on the blue paper.
So if you connect that analogy to this, DNA is actually the code that tells your cell how to do, what to do and such, they are actual genetic codes with bases such as Adenine, Guanine, Cytosine, and Thymine arranged in a double helix pattern. The chromosomes are the structures that are a result of arrangement of billions and billions DNA bases, thus they are the structures that house DNA and gene (part of DNA that codes for stuff)
