I believe it is called the cardiac muscle.
Your DNA is comprised of chromosomes which is comprised of genes. Your genes determine which inherited traits you receive from your parents. When you parents "make you" they each donate 16 chromosomes that contain many genes. These chromosomes make up your DNA, which effects your inherited traits such as, eye color, and hair color.
Hope this helps!
The atmosphere is divided into different regions, called layers. The layer closest to the surface is known as troposphere, after which comes the stratosphere. The stratosphere begins at an altitude of 10 miles above the surface of the earth and stretches up to 31 miles above the surface of the earth. It is the second layer of the atmosphere (beginning from the surface of the earth) and it is the region which contains ozone, which plays a vital role in stopping ultraviolet radiation from reaching the earth's surface.
Answer: When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.
Explanation:
Turgor is a phenomenon in plant cells in which the cell expands due to the pressure exerted by the fluids and also by the cell content on the walls. It is related to osmosis, since the external pressure is usually very high and this internal pressure dilates the cell as much as the elasticity of the membranes allows. <u>Then, the cells swell by absorbing water, tensing the membranes because of the pressure against them.</u> When the fluid exerts outward pressure on the cell wall it is called turgor pressure. Whereas, the inward pressure exerted on the cell contents by the stretched cell wall is called wall pressure. Generally, both pressures, turgor pressure and wall pressure, are counterbalanced and balanced.
So, this pressure of turgor facilitates the elongation of the cells in the plant, and also, the cells use this phenomenon to regulate the transpiration through the opening and closing of the stomach.
Thereby, the turgor of a living cell is influenced by three primary factors:
- An adequate supply of water.
- The formation of osmotically substances.
- A semi-permeable membrane.
Vacuoles are organelles bounded by a single membrane and present in plant and fungal cells, and where water is stored. Plant cells control their turgor pressure through the movement of water into or out of vacuoles. When wilted plants are given water, it enters the cell generating turgor and giving a firmer appearance, and this water is stored in the vacuoles.
Let us consider each statement separately. A zygote is the result of the fusion of two gametes (reproductive cells) and thus only appears in sexual reproduction. For the same reason, E) is wrong; meiosis is a step in the making of gametes and again, a plant that reproduces asexually does not produce gametes. B) is also wrong since (healthy) members of the same species have the same number of chromosomes. The leaf cells of the daughter plant will have 24 chromosomes. The only case where this would not hold, is the case of sexual reproduction, where the gametes of the new organism have half the chromosomes of the ancestor organisms. Hence, C and D are correct. We have already justified D. As far as C is concerned, in asexual reproduction we have that every organism passes his whole genome to his offspring and this creates a lot of clones next to each other. Every plant in a garden of a species that reproduces asexually may be genetically identical and some biologists consider them for that reason as the same organism!
