Describe how Eukaryota plant cells store remove waste materials?

Biology
2 answers:
zloy xaker [14]3 years ago
4 0

 They convert a lot of their waste into useful substances through photosynthesis. Gaseous wastes are excreted during respiration through the plant's stomata and root cell walls. At night, when photosynthesis cannot occur, excess water is released through the tips of the leaves.

Other waste products are released as leaves and flowers fall off of a plant. In addition to oxygen, water and carbon dioxide, other plant waste products include resins, saps, latex and tannins. Some of these products are released into the soil surrounding the plant.

<h2>ANSWER:</h2>

They transform a lot of their waste into valuable substances through photosynthesis

<h2>EXPLANATION:</h2>

They convert a lot of their waste into valuable substances through photosynthesis. Volatile wastes are eliminated during respiration through the plant's stomata and root cell walls. At night, when photosynthesis cannot happen, excess water is discharged through the tips of the leaves.Additional waste products are discharged as leaves and flowers drop off of a plant. In extension to oxygen, water, and carbon dioxide, other plant waste products comprise resins, saps, latex, and tannins. Several of these products are delivered into the soil circling the plant.

The ratio of the ages of father and son is 9:2 if the father is 45 year old, find the son
wolverine [178]
If the ratio is 9:2 that means that 45 would by ñ times 9. At the same time, ñ must also fit the ratio. Using this knowledge, you can divide 45 by 9, giving you 5, then multiply it by 2. This means that the child is 10 years old.

How were you able to determine if something was living, once living, or never living (non-living)?
snow_lady [41]

Answer:

Must have lived before.

Explanation:

For an organism to be classified as once living, an object must have been part of a living organism or is now dead. When a flower is plucked from a plant it is hard to distinguish between when it is considered alive and when it is now considered once living. An example of a nonliving object is an apple or a dead leaf.Apr 22, 2013

What is an advantage of performing a series of dilutions vs. a simple dilution?
Marrrta [24]

<u>Answer:</u>

The series dilution method is the step wise dilution technique where the dilution factors remain constant in each step.  

The advantages of using the series of dilution method over simple dilution are stated below:

<em>a)        Aids in reduction of a dense culture of cells to a more usable concentration.</em>

<em>b)        In every step of dilution the specific amount of bacteria is removed. </em>

<em>c)        Helps in the estimation of concentration of an unknown sample.</em>

<em>This sums up the advantage of using the series dilution technique.</em>

What would a biochemist call the result of chaining many molecules together
maxonik [38]

The structure of a typical antibody molecule

Antibodies are the secreted form of the B-cell receptor. An antibody is identical to the B-cell receptor of the cell that secretes it except for a small portion of the C-terminus of the heavy-chain constant region. In the case of the B-cell receptor the C-terminus is a hydrophobic membrane-anchoring sequence, and in the case of antibody it is a hydrophilic sequence that allows secretion. Since they are soluble, and secreted in large quantities, antibodies are easily obtainable and easily studied. For this reason, most of what we know about the B-cell receptor comes from the study of antibodies.

Antibody molecules are roughly Y-shaped molecules consisting of three equal-sized portions, loosely connected by a flexible tether. Three schematic representations of antibody structure, which has been determined by X-ray crystallography, are shown in Fig. 3.1. The aim of this part of the chapter is to explain how this structure is formed and how it allows antibody molecules to carry out their dual tasks—binding on the one hand to a wide variety of antigens, and on the other hand to a limited number of effector molecules and cells. As we will see, each of these tasks is carried out by separable parts of the molecule. The two arms of the Y end in regions that vary between different antibody molecules, the V regions. These are involved in antigen binding, whereas the stem of the Y, or the C region, is far less variable and is the part that interacts with effector cells and molecules.

Peer-raised macaques show neurological differences from those macaques raised by adults; they have less developed neural network
Genrish500 [490]

This is an example of an Epigenetic effect.

Explanation:

It is the study of heritable changes in the expression of genes, that are not involved in the changes present in DNA sequence. It is regular and naturally occurred, sometimes factors are responsible like age, lifestyle and disease state.

At times it leads to more damaging effect that can cause cancer. So this is also related to various fatal disease. During adulthood epigenetic effect remains stable. It does not occur in mother womb, but during the lifespan. This epigenetic effect can be reversed.
