Design an experiment using a seedling and a block of agar soaked with auxins that might con firm the effect of this hormone on the elongation of the coleoptile. (Hint: Remember that the auxins are permeable to the agar material.)
Answer:
Grow the seedlings of oats for Avena coleoptile test in a petri plate and let them germinate in light, so that the coleoptile forms with leaves.Cut the coleoptile stem and add agar block of auxin with different concentrations in all different oat seedlings and expose them to sunlight.Then observe the amount of bending of coleoptile stem towards the light in different samples added with different amount of auxin in the agar slab.
Explanation:
Cultivate oat saplings in a petri dish for the Avena cotyledon experiment and let them germination in light until the coleoptile develops with branches.
Cut the coleoptile stems and place an agar blocks with varying quantities of auxin in each of the oat saplings before exposing them to sunlight.
Next, in separate samples with varied amounts of auxin inside the agar slab, examine the degree of bending of the coleoptile branch more toward the sunlight.

ways in which seed dormancy can be broken
Answer:
Seed dormancy is defined as the process in which seed are prevented from germination even though environmental conditions are favoring.
There are several ways in which seed dormancy can be broken. Some of them are as following:
Scarification: scarification is a mechanical technique to breakdown the seed dormancy. In this technique, hard seed coat is removed from the seed under cold temperature.
Hot water treatment: The seed is kept into hot water between the 75 degree to 100 degree, that helps in removal of seed coat and allow germination of plant.
Sodium hypochlorite solutions: sodium hypochlorite (NaOCl) solution breakdown the seed dormancy by decomposing germination inhibitors, increases α-amylase activity and scarifying the seed coat.
Hence, three ways to break seed dormancy are Scarification, Hot water treatment, and Sodium hypochlorite solutions.

Name 4 things that happen during telophase.
Answer:
1. The chromosomes arrive at the cell poles.
2. The mitotic spindle disassembles.
3. The vesicles that contain fragments of the original nuclear membrane assemble around the two sets of chromosomes
4. Separate the nuclear DNA from the cytoplasm.
answer:
During telophase, the chromosomes begin to uncoil and form chromatin. This prepares the genetic material for directing the metabolic activities of the new cells. The spindle also breaks down, and new nuclear membranes (nuclear envelope) form.

Which action is most likely to stop succession and make an ecosystem less
stable?
O A. Using fewer pesticides in gardens
B. Using less fertilizer in gardens
C. Planting a variety of native species in gardens
D. Planting nonnative species in gardens
The answer is D. Because planting nonnative species is bad for the area because the plants that normally grow there have to compete with that new species then.
Answer:
D. Planting nonnative species in gardens.
Explanation:
Planting nonnative species in gardens are bad for your garden. The nonnatives can steal most to all of your native plants food and they can attack your native plants and kill them.

The Maplewood Marine Restoration Project will seek to dredge sand and substrate from the
southwest of the site to create a drainage channel in the Maplewood basin. This will create a ______
supporting fish and invertebrate communities. The substrate
will be used to fill in the northeastern corner of the basin to make a mudflat that supports and
shellfish in______
and juvenile salmonids and crabs in
_______(figure 3.3)
options are:
rock reef habitat
intertidal flat habitat
shallow subtidal eelgrass
Answer: shallow subtidal eelgrass, intertidal flat habitat, rock reef habitat
Explanation:
The project will seek to dredge sand and substrate from the
southwest of the site to create a drainage channel in the Maplewood basin. This will create a shallow subtidal eelgrass
supporting fish and invertebrate communities. The substrate
will be used to fill in the northeastern corner of the basin to make a mudflat that supports and
shellfish in intertidal flat habitat
and juvenile salmonids and crabs in
rock reef habitat(figure 3.3)
This is the passage that we will get after we add those two habitats from your question which are rock reef habitat, and intertidal flat habitat, and also shallow subtidal eelgrass.
Rock reef habitat is opposite to intertidal flat habitat because it is not flat it is the place when fishes can hide or live.
Eelgrass is considered a flowering underwater plant.

Which of the following statements DOES NOT accurately describe the experimental design used by Fred Griffith?
A.The type of bacteria injected into the mouse was the independent variable in his experiment. B.The injection of the live rough bacteria into the mouse is a control because it was used as a standard of comparison for other experimental setups.
C.The dependent variable in the experiment was the health of the mouse after injection.
Answer:
The correct answer is B. It is false that the injection of the live rough bacteria into the mouse is a control because it was used as a standard of comparison for other experimental setups.
Explanation:
The experiment conducted by Frederick Griffith in 1928 was one of the first experiments to show that bacteria could transfer genetic information.
Griffith used two slightly different pneumococcal strains in his experiment. One of them was harmless to the mice, while the other was not. Using each strain separately, the logical thing happened: the mice died with the fatal strain, and nothing happened with the harmless.
Then, Griffith killed the deadly strain, and mixed both strains, introducing them into the mice. After this, the mice died, which allowed us to verify that the bacteria can transfer genetic material even after dying, through the transformation process.
A red blood cell is 7.5 µm in diameter. It is magnified 2000 times. Calculate the diameter of the image seen through the microscope in millimetres.
Answer:
15 mm
Explanation:
Given that,
The diameter of a RBC = 7.5 µm
It is magnified 2000 times.
We need to find the diameter of the image seen through the microscope in millimeters.
The size of the diameter is given by :
[tex]d=2000\times 7.5\\\\=15000\ \mu m\\\\or\\\\d=15\ mm[/tex]
So, the diameter of the image seen through the microscope is 15 mm.

In the diagram below, which cells are involved in the process of sexual reproduction? A.) cell 3, only B.) cell 1 only C.) cell 1 and 2 D.) cell 2 and 3
Cell 1 and 2 are involved in the process of sexual reproduction which are sperm and egg respectively.
What are gametes?Gametes are reproductive cells that are responsible for sexual reproduction. In animals and plants, gametes are typically specialized cells that are specifically designed for the purpose of reproducing and transmitting genetic information from one generation to the next. Gametes are produced by the process of gametogenesis, which is the process of forming and developing gametes.
In animals, gametes are typically either eggs (ova) in females or sperm in males. Eggs are large, non-motile cells that contain a large amount of cytoplasm and nutrients to support the development of an embryo. Sperm are smaller, motile cells that are specialized for fertilization and are capable of swimming through the female reproductive tract to reach the egg.
In plants, gametes are typically produced by specialized cells called gametophytes. Gametophytes produce gametes through a process called meiosis, which is a type of cell division that results in the production of four genetically diverse daughter cells. The gametes produced by gametophytes are typically small and non-motile, and they are capable of fusing with gametes from other plants to produce a fertilized egg, or zygote.
