A sample of digestive juice was removed from the stomach of a pig. The juice was
placed in a test tube along with some grains of wheat. A second test tube was set up
containing an equal number of wheat grains, with distilled water rather than
digestive juice. The test tubes were kept for 8 hours at 40 degrees C. After 8 hours,
the grains inside the digestive juice had broken into tiny particles. The grains of
wheat, in the water, were wet but otherwise unchanged.
What is the control group?
test tube with wheat and water
test tube with wheat and digestive juice
the same temperature
the presence or absence of digestive juice
Answer:
The control group is the test tube with wheat and water.
Explanation:
This is because the control group is set up to be compared to the outcome of the test subject influenced by the independent variable, which is this case is the digestive juice. The water and wheat shows the true effect of the digestive juice on breaking down part of a pig's diet, which is wheat.

Alab technician needed to make a wet mount slide of their cheek cells. The tech made
his slide and placed it on the microscope stage. Then he got ready to view his cheek
cells by following these procedures.
1. Looking through the eyepiece, the technician adjusted the diaphragm so field of
vision was lit.
2. The technician looked at the stage from the side and lowered the body tube so the
high power objective was almost touching the slide.
3. Looking into the eyepiece, he very slowly turned the coarse adjustment to bring the
cells into focus.
What suggestion would you make to the technician to CORRECTLY use the microscope
to view his cheek cells?
do not look at the stage when lowering the body tube
The question is incomplete as it does not have the options which are:
A) close the diaphragm
B) start with the low power objective
C) do not look at the stage when lowering the body tube
D) start with the body tube raised and lower it while looking through the eye piece
Answer:
Option-B
Explanation:
In the given question, the technician is trying to observe the cheek cells in the light microscope. The person prepares the wet slide of the sample and tries to observe the sample using the protocol provided in the question.
In these options, the technician is not following the rules to observe the slide in the microscope that always observes the specimen using an objective lens with lower power. Then increase the power of the objective lens to increase the magnification of the sample.

In what two ways do plants keep our climate stable over time?
Answer:
Through transpiration and use of carbon dioxide (green house gas)
Explanation:
Plants help in making the climate stable in following two ways –
a) Temperature offsetting – Plants take in carbon dioxide from atmosphere and thereby reduces atmospheric carbon. Due to reduction in greenhouse gases, the temperature reduces.
b) Moisture regulation – Plants transpire through their leaves. Through transpiration, they release water as vapor and cool down the air. The higher the vegetation , the more is the transpiration.
Which of the following results in greater genetic variation in offspring?
A. meiosis
B. both mitosis and meiosis
C. mitosis
D. neither mitosis nor meiosis
Answer:
A. meiosis
Explanation:
Meiosis results in greater genetic variation in offspring compared to mitosis due to processes like crossing over and independent assortment. Mitosis produces genetically identical cells, while meiosis combines genetic material from two parents. Meiosis II is similar to mitosis, and fertilization leads to the formation of a diploid cell.
The greater genetic variation in offspring results from meiosis, not from mitosis. Equal segregation of alleles into daughter cells happens during both mitosis and meiosis. However, genetic variation is specifically introduced during meiosis through mechanisms such as crossing over, independent assortment, and the combination of genetic material from two different parents during fertilization. Mitosis produces genetically identical cells, hence it does not lead to genetic variation.
The part of meiosis that is most similar to mitosis is meiosis II, because it is essentially a mitotic division of the haploid cells formed during meiosis I. Furthermore, the event that leads to a diploid cell in a life cycle is fertilization.

Which observations would be most helpful in identifying this spider? Check all that apply.
It is shiny black.
It has a red spot on its abdomen.
It has eight legs.
It has a round, plump abdomen.
It has a hard exoskeleton.
Answer:
A, B, D
Explanation:
Important observations for spider identification include a shiny black color, a red spot on the abdomen, eight legs, a plump abdomen, and a hard exoskeleton. A red spot, especially shaped like an hourglass, often indicates a black widow spider.
To identify a spider, certain observations are most helpful. Observations such as a shiny black color, a red spot on the abdomen, the presence of eight legs, a round plump abdomen, and a hard exoskeleton would all contribute significantly to spider identification. Notably, the red spot on the abdomen is distinctive of the black widow spider, which is known for its venom that can be toxic to humans. All spiders, as arachnids, possess certain characteristics such as eight legs, which distinguishes them from insects. Distinguishing features like leg length, hairiness, and relative size of body segments can assist in classifying spiders into groups.

Write a couple paragraphs about how producers (plants) get their energy from the sun and animals that eat them take their energy and other animals eat them.
Answer:
First, plants receive and trap the sunlight using chlorophyll, the green substance that make up the color of the plants. Water (H2O) and carbon dioxide (CO2) from humans are also needed. The plants make their food (sugars) in this process called photosynthesis.
Second, animals consume the plants and obtain the energy from the plants. Animals cannot survive without plants, for plants produce oxygen and energy. Animals are heterotrophs, while plants are autotrophs. After the animals obtains the energy, they breathe carbon dioxide out.
Lastly, this process repeats over and over again. Plants are very important in animals' lives. This is why everyone wants to stop pollution and plant elimination. All in all, plants and animals rely on each other, and they cannot survive without each other.
Hope this helps!
Does the law of reflection hold true for mirrors that aren’t flat ?
The law of reflection applies to both flat and curved mirrors, stating that the angle of incidence equals the angle of reflection. Curved mirrors, such as convex and concave mirrors, reflect light in a way that alters the image size, orientation, and whether it's real or virtual. The size of the object does not change the laws of reflection, which can be confirmed through optical experiments.
Explanation:The law of reflection states that the angle of incidence is equal to the angle of reflection, with the incident ray, the reflected ray, and the normal (the line perpendicular to the surface) all lying in the same plane. This law applies to both flat and curved surfaces such as mirrors. When considering a flat mirror, the law of reflection leads to virtual images which are the same size as the object. The image appears as far behind the mirror as the object is in front of it.
In the case of a convex or concave mirror, the reflection still obeys this fundamental law, but the curvature of the mirror causes the reflected rays to diverge or converge, which affects the characteristics of the image. The /size, orientation, and type (virtual or real) of the image can vary/ based on the distance of the object from the mirror and the focal point. For example, in a concave mirror, when an object is closer than the focal point, the image is virtual and enlarged; beyond the focal point but closer than twice the focal length, the image is real and inverted. When the object is further away than twice the focal length, the image is smaller and still inverted.
Regarding the question of whether the /size of the object changes the laws of reflection/, it does not. The laws remain constant, but the size of the object can affect the visibility and the extent of the reflected rays across the mirror's surface, particularly for curved mirrors. In optical experiments, using flashlights and mirrors, the law of reflection can be observed and confirmed, either with a plane mirror producing predictable reflection angles or with curved mirrors that focus light in specific ways, like in flashlights or concert shells.
