Which of the following are not characteristics of the cell wall? Select all that apply. cellulose and chitin hydrophillic and hydrophobic structures found in cells of fungi and algae double-layered membrane

Answer: hydrophobic and hydrophilic structures found in cells of fungi and algea

double-layered membrane

A cell wall is a a semi-permeable protective layer found in some cell types. This covers the cell membrane in plants cells, fungi, bacteria. Animal cells do not possess cell wall. The cell wall performs functions like protection, provides structural stability to a cell and support. Cell wall composition varies depending upon the type of organism. In plants the cell wall is made up of fibers of carbohydrate polymer called as cellulose. In bacteria cell walls are made up of peptidoglycan. In fungi cell wall is made up of chitin. Hydrophillic and hydrophobic structures found in cells of fungi and algae and double- layered membrane are features of cell membrane not of cell wall.

Which of the following does this chart represent? Promotes Growth Controls Tropisms Controls Budding Flowers Abscisis x Auxins x Cytokinins x Ethylene x Gibberallins x x A The completed plant tissues and the cells that initiate their growth B The relationship between different types of plant hormones and their functions C The differences between plant structures and the hormones they produce D The types of plant cells and their functions within the plant

Ans.

Plant hormones are signalling molecules, produced b plants that regulate growth, development and other cellular processes of plants. There are five types of plant hormones, which include abscisic acid, auxins, cytokinins, ethylene, and gibberallins.

Given chart represents relationship between different plant hormones and their responses or functions. Auxin promotes plant growth, plays role in tropism, abscisic acid plays role in seed and bud dormancy, cytokinin promotes cell division, ethylene controls plant growth and stimulates flowering, and gibberallins cause stem elongation.

Thus, the correct answer is option (B).

Sickle-cell disease is a genetic disorder that causes many red blood cells to become sickle shaped. As shown in the diagram, sickle-shaped cells can clog blood vessels and impede blood flow. What does the effect of sickle-shaped cells on blood flow imply about the shape of normal red blood cells?

Answer:

The answer is :

Blood viscosity increases and results in decreased blood flow throughout the body.

Explanation:

Blood flow is directly proportional to pressure and indirectly proportional to resistance.

Sickle-shaped blood cells tend to accumulate and increase the blood viscosity, which increases resistance. Therefore, blood viscosity increases and results in decreased blood flow throughout the body.

A small child managed to eat a bit of dirt while playing outside. Which of the following would prevent the child from getting sick from the bacteria ingested? A If there were not a pathogenic bacteria in the dirt B If the child had previously taken antibiotics for that type of bacteria C If the child already had the antibodies to fight the bacteria D If the child’s cells had complementary receptor molecules that bind to the bacteria

Answer:

C If the child already had the antibodies to fight the bacteria

Explanation:

There are a lot of bacteria that we have already storage antibodies for, our immune system is like a database of antibodies that learns with every disease we get, some of them won´t even manifest, because our immune system is strong and produces enough antibodies to counterattack the germs. So from the options given, the most reasonable and possible is that the kid already had the antibodies to fight that bacteria.

Which is a characteristic of diatoms? whip-like tail heterotrophic multicellular glass-like cell wall

Answer: glass-like cell wall

Diatoms are unicellular organisms, they live in fresh as well as in saline water. They exhibit two distinct shapes such as centric diatoms which are radially symmetric and others are pennate diatoms which are bilaterally symmetrical. All types of diatoms possess a cell wall that is made up of silica, it is called as frustule. The silica provides a resistance against the decay of the diatom cell. The cell wall looks like a glass.

QUESTION POSTED AT 28/03/2020 - 10:56 AM

The central vacuole in a plant cell is responsible for turgor pressure. When the vacuole loses water the cytoplasm "shrinks". When the vacuole gains water the cytoplasm seems to "puff up". One structure helps the plant cell keep its shape no matter how much water is in the vacuole. This is the A) cell wall. B) cytoplasm. C) cytoskeleton. D) cell membrane.

Answer:

The correct answer would be A) cell wall.

In a plant cell, the cell wall is the outermost layer mainly composed of cellulose. It provides protection, support, structure et cetera to the cell.

It provides mechanical support and strength to the cell and regulates the direction of cell growth.

It helps the cell in withstanding the turgor pressure and thus, helps in preventing the bursting of a plant cell in hypotonic solutions. In addition, it also prevents the shrinkage of the cell in hypertonic solutions.

It also protects the cells from invading pathogens such as viruses.

The graph shows the changing levels of hormones during menstruation and ovulation. What happens to hormone levels during ovulation, and why is this important? a.The hormone levels increase to prepare a woman’s body to receive a fertilized egg. b.The hormone levels decrease to prepare a woman’s body to receive a fertilized egg. c.The hormone levels increase, and the next menstrual cycle begins with shedding of the uterine lining. d.The hormone levels decrease, and the next menstrual cycle begins with shedding of the uterine lining.

The given graph shows the levels of the different hormones during the period of ovulation. During the phase of the ovulation, the hormones level increase. This increase in  the levels of the hormones prepare the uterus for the fertilization of the egg. The uterine line is thickened. This is the phase when the LH  (Luteinizing hormone) surge occurs, which refers to the sudden increase in the levels of LH. Moreover, the levels of FH, estradiol, and progesterone are also increased at different rates during ovulation.

Hence, the correct answer is 'option A - The hormone levels increase to prepare a woman's body to receive fertilized egg'.

Blastula cells are stem cells, why is this so important?

A single-celled zygote will undergo multiple rounds of cleavage, or cell division, in order to produced a ball of cells, called a blastula, with a fluid-filled cavity in its center, called a blastocoel.In animals with little yolk in the egg, the zygote undergoes holoblastic cleavage, in which the entire zygote is cleaved repeatedly; in animals with a lot of yolk in the egg, the zygote undergoes meroblastic cleavage, in which only part of the zygote is cleaved.The blastula eventually organizes itself into two layers: the inner cell mass (which will become the embryo) and the outer layer or trophoblast (which will become the placenta); the structure is now called a blastocyst.During gastrulation, the blastula folds in on itself to form three germ layers, the ectoderm, the mesoderm, and the endoderm, that will give rise to the internal structures of the organism.
