Answer:
Murine, primate and human embryonic stem cells (ESCs) exhibit a very unusual cell cycle structure, characterized by a short G1 phase and a high proportion of cells in the S-phase.
Explanation:
Normally, embryonic stem (ES) cells proliferate quickly during differentiation and do not differentiate simply by cell cycle slowing. In this paper, it is shown that the role of the cell cycle in terminal stages of differentiation can be adapted for and extended into ES cells.
Answer:
Photosynthesis and respiration are reactions that complement each other in the environment. They are in reality the same reactions but occurring in reverse. While in photosynthesis carbon dioxide and water yield glucose and oxygen, through the respiration process glucose and oxygen yield carbon dioxide and water.
Explanation:
Photosynthesis makes the glucose that is broken down by cellular respiration. Cellular respiration converts the glucose that is made by photosynthesis to oxygen. Photosynthesis converts the glucose that is made by cellular respiration to carbon dioxide
C) A virus since it isn't actually a living being nor is it a cell, which would have a nucleus.
Discharge is the act of removing or losing charge. If the velocity increases, the discharge would increase (i'm guessing that the width and depth of the area is increasing).
The main aspect used to differ coniferous tree are their leaves. Coniferous leaves look like elongated needles, instead of the regular flatend out leaves we're used to
Further characteristics:
Seeds are hard and grow in large groups, stuck to eachother.
Coniferous are evergreen trees (don't shed leaves nor change the colour of these, although this rule does not apply to all of them).
They have spread worldwide.
Can withstand low temperaurees and can be found even in places like the Artic circle.
I've pasted some images down below that might help you a lot. (Left - leaves; Right - coniferous trees).
Hope it helped,
Happy homework/ study/ exam!
