Hope i helped, good luck on the test :)
The statement which is true about Fungi are as follows:
The reproductive organs of a fungus are the Mycelium, an underground network of threads.Thus, the correct option is D.
What are Fungi?Fungi may be defined as a group of eukaryotic organisms that lack chlorophyll, leaves, true stems, and roots, reproduce by spores and live as saprotrophs or parasites.
Due to the absence of chloroplasts, fungi are not similar to plants. Fungi are eukaryotic heterotrophs organisms.
Spores are the fundamental reproductive units of fungi. The reproductive organs of a fungus are the Mycelium which is hidden until it is able to develop one or more fruiting bodies.
Therefore, the correct option for this question is D.

Independent variable:
I
Dependent variable:
Control:
Answer:
Explanation:
An independent variable can be described as the variable that is intentionally altered during the experiment by the researcher and is not affected by any other variable involved in the course of the experiment. From this description, the independent variable in the question are the "plastic wraps".
A dependent variable can be described as the variable that is been experimented on or has the tendency to be affected by the independent variable. From this description, the dependent variable here is the "time" it will take for the bread to mold.
The control of an experiment can be described as the "normal" or the "standard" experiment in which other experiments in the same research of the same nature are compared with. From this description, the control of this experiment is the experiment done involving the clear plastic wrap.

Consider two different traits in mice affecting tail length and fur color. A two-factor cross was made involving true-breeding mice with short tails and white fur to wild-type mice with long tails and brown fur. All F1 offspring had long tails and brown fur. The F1 offspring were then crossed to mice with short tails and white fur. The following phenotypic results were obtained:
118 long tails, brown fur 77 long tails, white fur 114 short tails, white fur 81 short tails, brown fur
Required:
Construct a null hypothesis about these two genes and the expected ratios of the offspring from the cross.
Answer:
See the answer below
Explanation:
Null hypothesis: The two genes are independently assorting and therefore, are not linked to each other.
Let A represents the allele for tail length and B for fur color. Long-tail A is dominant over short tail a while brown fur B is dominant over white fur b.
For the first cross involving true-breeding mice:
AABB x aabb
F1 AaBb (long tails and brown fur)
For the second cross:
AaBb x aabb
4 AaBb - Long-tail, brown fur
4 Aabb - Long tail, white fur
4 aaBb - short tail, brown fur
4 aabb - short tail, white fur
Since the phenotypic ratio from the cross is 1:1:1:1, if the null hypothesis was to be true, it means that the expected phenotype ratio should be 1:1:1:1.
In order to test this hypothesis, we use Chi-square:
phenotype O E X^2
Long-tail, brown fur 118 97.5 [tex]\frac{(118-97.5)^2}{97.5}[/tex] = 4.31
Long tail, white fur 77 97.5 4.31
short tail, brown fur 81 97.5 2.79
short tail, white fur 114 97.5 2.79
Total 14.2
Degree of freedom = 4 - 1 = 3
Critical Chi-square value = 7.815
The calculated Chi-square value is more than the critical value, hence, the null hypothesis is rejected.
Which statement best describes a benefit of conducting a comparative investigation over collecting data from the Internet?
1 A comparative investigation can be repeated in a short time while collecting the continuous data from the Internet takes longer.
2Conducting a comparative investigation is always less expensive than an investigation in which data is obtained from the Internet.
3 Conducting a comparative investigation is always less time consuming than obtaining data from the Internet.
4 A comparative investigation can provide a wider range of data than can be obtained from the Internet.
Answer:
The correct option is 4
Explanation:
Comparative investigation involves the collection of data from different "subjects" (including organisms, object or characteristics) or obtaining data under different conditions (such as seasons, years or locations) for the purpose of comparison. This type of investigation is both time and capital intensive; meaning it requires a lot of time and money. It however provides a larger and wider range of data that might not be available through other "independent investigations" because a large amount of subjects is usually studied for proper and accurate comparisons.

c. create matrix of connective tissue - 1. fibroblasts
d. secrete pigment melanin - 5. melanocytes
e. cause inflammation - 7. mast cells
f. second most abundant cell type and maintain matrix - 2. fibrocytes
g. specialized cell of the immune system - 8. lymphocytes
h. large phagocytic cells of the immune system - 6. macrophages
i. fat cells - 3. adipocytes
Explanation:
Almost all of these cells have one thing in common: they are part of the connective tissues in our body. Connective tissue can be divided into two: proper connective tissue (that can be loose or dense) and specialized connective tissue (in this category, for example, we can find blood tissue, adipose tissue, bone tissue, and cartilage tissue).
Cells in our bodies have very different but important functions and they partake in their tasks because of the specific tissue or organ where they are at. While blood tissue has cells that specialize in gas transport and immune response, the connective tissue has cells that synthesize and maintain the matrix and also specialized immune cells as well. Microphages, macrophages and lymphocytes can be found both in the blood tissue and the connective tissue as well, as they migrate from the bloodstream to the tissue where they are needed to perform immunity tasks. Also in the connective tissue, we can find other cells that participate in the immune response, like the mast cells that release histamine to produce inflammation.

Explanation:
A flying object is moving at 150 m/s. It makes a complete and final stop in 12 seconds. Calculate the object’s acceleration.
plzzzzzzzzzzz
Answer:
12.5m/s^2
Explanation:
Acceleration of an object can be calculated by using the formula;
a = v-u/t
Where; a= acceleration
v= final speed
u= initial speed
t= time
According to this question, the flying object is moving at 150m/s, meaning that ∆V = (v-u) is 150m/s, where initial speed is 0m/s.
Since time is 12s, the acceleration is thus:
a = 150-0/12
a= 150/12
a= 12.5
Hence, the acceleration of the flying object is 12.5m/s^2

A. carbon dioxide concentrations over opal increase.
B. average global temperatures will continue to decrease rapidly.
C. the city of Miami, Florida, would be underwater.
D. the water surrounding Greenland will become more salty.
Answer:
Ice sheets contain enormous quantities of frozen water. If the Greenland Ice Sheet melted, scientists estimate that the sea level would rise about 6 meters (20 feet). If the Antarctic Ice Sheet melted, the sea level would rise by about 60 meters (200 feet).
So, most likely, C. the city of Miami, Florida, would be underwater.

More the density of liquid, then
(a) Slower the sound travel
(b) Faster the sound travel
(c) More distance covered by the sound
(d) Less distance covered by the sound
Answer:
(a) Slower the sound travel
Explanation:
The speed of sound also depends on the material it is traveling on. The denser the liquid, the slower the sound can travel and the less denser the liquid, the faster the sound can travel. This is because denser materials have larger molecules than less denser materials. Sound waves travel through "vibration." It takes more energy to vibrate in denser objects than in less denser ones; thus this explains the slow travel rate of sound in a denser medium of liquid.

If 1/32 of a parent material is left, compared to 31/32 of daughter, and the half-life is 50,000 years, then how
old is the sample?
--
Answer:
251449 years
Explanation:
We can obtain the age of the sample by using the formula;
t1/2 = t ln2/ln(No/Nt)
Where;
t1/2 = half life = 50,000 years
t= elapsed time = the unknown
No = amount of radioactive material originally present
Nt= amount of radioactive material after time (t)
Note;
Since Nt/ No = 1/32
Then No/Nt= 32/1
Substituting values
t= t1/2 ln(No/Nt)/ln 2
t= 50000 × ln(32/1)/ln 2
t= 50000 × 3.47/0.69
t= 251449 years

ribosomes are the most
essential organelle in the cell. Include Evidence of at least 3 organetles that support the ribosome in accomplishing its fonction for at the cell.
Answer: Ribosomes work along with most of the organelles because they make the proteins that they need to perform. Mitochondria, which generate energy by breaking down carbohydrates, and chloroplasts, which store energy as sugar for plants, algae and some fungi, have their own DNA along with ribosomes to read its instructions. Messages from the nucleus are sent into the endoplasmic reticulum where the ribosomes are located.
Explanation:
The ribosome primarily functions as an organelle for the synthesis of proteins. The 3 organelles that help ribosomes in accomplishing their functions include the nucleus, the Golgi apparatus, and the endoplasmic reticulum.
In order to successfully synthesize proteins, hereditary information on DNA must first be transcribed into genetic codes as messenger RNA in the nucleus. Thereafter, the mRNA undergoes some processing before being transported from the nucleus to the cytoplasm where it binds with the ribosome and gets translated to amino acids.
The amino acids are linked together by peptide bonds to form the primary structures of proteins. The proteins are then folded in a specific manner by the Golgi apparatus depending on the functions they are to perform.
After folding, the synthesized proteins are then transported to their target sites by the same Golgi apparatus via the channels created by another organelle known as the endoplasmic reticulum.
