The minerals that make up rocks give them their unique properties. Based on your results, do you think that any of your three rocks have the exact same mineral make up, or are they three different types of rock? Explain your answer.
Rocks doesn't have the exact same mineral make up as they are made of different composition.
How to illustrate the information?A naturally occurring collection of minerals and/or mineraloids is called rock. There is no known chemical makeup of rocks.
Minerals are naturally occurring substances with unique atomic structures, compositions, and chemical and physical properties. Typically, two or more minerals are mixed together through geological processes to form rocks.
Because of their minerals, formation processes, and processes that have affected the rocks since they were formed, various rocks have different properties.
Rocks are composed of minerals and have a wide range of traits or properties. When a rock is ground into a powder, it takes on the color of streak, and a rock's luster indicates how shiny it is. Other characteristics include size, shape, texture, and hardness.

O Microorganisms reproduce asexually, producing identical offspring
O Corn is genetically modified and cloned to make identical crops
O Penguins reproduce sexually, producing offspring that look different from one another
O A banana tree branch is planted, producing a clone of the parent tree
Evolution by Natural selection occurs when the offspring of genotypes are produced in response to the environment. Hence the correct option is C Penguins reproduce, offspring that look different from one another.
Evolution by Natural SelectionCharles Darwin and Alfred Russel Wallace developed the theory of Evolution by Natural Selection. For evolution by natural selection take place, Darwin described four essential conditions, these are:
Trait selection must be variable in the populationThe trait must be heritableThe struggle of existenceThe organism which fits to its environment.As per the question, penguins produced offspring that look different from another, this must be because of the evolution by Natural selection.

Why is it difficult to find the fish named after former president Barack Obama
Many bony fish species have a swim bladder: an air-filled organ that can inflate to help them float up in water or deflate to help them sink down. What can you infer about a species that lacks this organ?
A species that lack a swim bladder, a fish without buoyancy issues will often stay still and erect in the water.
What is a swim bladder?You will notice excessive fin movement if your fish are trying to keep upright or are swimming sideways or upside down as they attempt to float correctly.
Thus, we may draw the conclusion that the swim bladder's air capacity rises as the fish dives deeper.
You might be shocked to learn that the majority of bony fishes have a swim bladder, a particular organ that helps them with that.
Therefore, this is a gas-filled sac with a thin wall that is found inside a fish's body.

Dinoflagellates are a diverse group of marine microorganisms that possess the ability to perform photosynthesis and produce oxygen.
What are dinoflagellates?Dinoflagellates are a diverse group of aquatic microorganisms that belong to the kingdom Protista. They are characterized by their distinctive whip-like flagella, which allow them to move through the water. Dinoflagellates are found in both marine and freshwater environments, and they can be found in a wide range of habitats, from the open ocean to estuaries, lagoons, and even in soil. They are a type of phytoplankton and play a critical role in the oceanic food web and global biogeochemical cycles.
Some dinoflagellates are photosynthetic, meaning they can produce their own food through the process of photosynthesis, and can produce oxygen. They are an important primary producer of marine food webs and support the entire marine ecosystem. However, some dinoflagellates produce toxins that can be harmful to marine life, as well as humans and can cause blooms or "red tide" phenomenon.

A group of biologists working in Africa observed that some of the Acacia trees growing in their study plots had clearings around them, so that no other vegetation grew within a few meters around each tree. These trees were also covered with ants. The researchers hypothesized that the ants must have cleared the vegetation around each tree. To test this, the researchers decided to remove the ants from some of the trees by spraying with an insecticide and see if vegetation grow in the clearings with the ants gone. They located 100 Acacia trees with clearings and ants present, and sprayed half of them with insecticide. The trees tended to exist in two general habitats: the first habitat was much higher in elevation and was moisture, cooler, and had more wind exposure than the second habitat. Because the insecticide spray would have drifted in the windy conditions of the higher elevation habitat, the researchers only sprayed trees in the low elevation habitat. They visited their research location once a month for two years to record whether vegetation re-grew in the clearings. Which element of experimental design is missing or flawed in this experiment
Answer:
The project showed no control over the confounding variable.
Explanation:
The confounding variable are variables that can influence the dependent variables and that were not established by the researchers. These variables exist naturally in the experiment and are able to alter the result of the experiment in a very intense way.
The dependent variable, in the case presented in the question above, is the proliferation of vegetation around the Acacia plants, while the independent variable is the amount of ants present in the environment. As we can see these two variables are being controlled by the researchers, however, the confounding variables such as soil fertility, water availability, sunlight intensity, wind intensity, are not being controlled and this can severely damage the experiment.
The element of experimental design that is missing or flawed is that the experiment did not control any confounding variable.
CONFOUNDING VARIABLE:A confounding variable in an experiment is a variable that can influence the outcome of the dependent and independent variables.
In this experiment, the dependent variable is case the proliferation of vegetation around the Acacia plants, while the independent variable is the amount of ants present in the environment.

Answer:

Explanation:
You are hired by Murphey Farms to decrease the backfat in their hogs. The current hog population has a mean backfat content of 20.2mm. You selected the hogs with the smallest amount of backfat, mated them and obtained the progeny generation. The selected hogs had a mean backfat content of 9.5mm. You know that the heritability for percent backfat in hogs is 0.47.
1. What is the selection differential? Round your values properly to 2 decimal digits.
2. What is the expected response to selection? Round your values properly to 2 decimal digits.
3. What is the expected mean of the progeny generation? Round your values properly to 2 decimal digits.
Answer:
SD = -10.7 R = -5.3X₁ = 14.9 ≅ 15mmExplanation:
Before answering the question, we need to know a few concepts.
Artificial selection is the selecting practice of a specific group of organisms in a population -that carry the traits of interest- to be the parents of the following generations.
Parental individuals carrying phenotypic values of interest are selected from the whole population. These parents interbreed, and a new generation is produced.
The selection differential, SD, is the difference between the mean value of the trait in the population (X₀) and the mean value of the parents, (Xs). So,
SD = Xs - X₀
Heritability in the strict sense, h², is the genetic component measure to which additive genetic variance contributes. The heritability might be used to determine how the population will respond to the selection done, R.
h² = R/SD
The response to selection (R) refers to the metric value gained from the cross between the selected parents. R can be calculated by multiplying the heritability h², with the selection differential, SD.
R = h²SD
R also equals the difference between the new generation phenotypic value (X₁) and the original population phenotypic value (X₀),
R = X₁ - X₀
-------------------------------------------------------------------------------------------------------------
Now that we know these concepts and how to calculate them, we can solve the proposed problem.
Available data:
• You are decreasing the backfat in the hogs.
• The hog population mean backfat content = 20.2mm → X₀
• The selected hogs had a mean backfat content of 9.5mm → Xs
• Heritability is 0.47 → h²
According to what we sow previously, we need to find out the value of X₁, which reflects how tall the new generation of corn will grow.
• We know that R = X₁ - X₀, so we need to clear this formula to calculate X₁
X₁ = R + X₀
We already know that X₀ = 20.2mm
Now we need to calculate R.
• R = h²SD
We know that h² = 0.47,
Now we need to calculate SD
• SD = Xs - X₀
Xs = 9.5mm → Parentals media height
X₀ = 20.2mm → Population media Height
SD = Xs - X₀
SD = 9.5 - 20.2
SD = -10.7
Knowing this, we can calculate R
R = h²SD
h² = 0.47 SD = -10.7R = 0.47 x -10.72
R = -5.3
Finally, once we know the R-value we can calculate the X₁ value
X₁ = R + X₀
X₁ = -5.3 + 20.2
X₁ = 14.9 ≅ 15mm

At 40°C, the temperature of sorghum could be lower than 40°C. True or False
Answer:
True.
Explanation:
The temperature of sorghum could be lower than 40°C when the surrounding temperature is 40°C because the sorghum plant absorb the sunlight and used it in the process of photosynthesis and the transpiration process regulate the body temperature of sorghum plant. Transpiration is the process in which water evaporated through a plant and its aerial parts, such as leaves, stems and flowers. This process removes extra heat with water through stomata so we can say that the temperature of sorghum is lower than 40°C.
Three unlinked genetic loci, each with two alleles, determine the differences in sugar content (and therefore sweetness) in a diploid fruit. These genes contribute equally to sugar content, and their effects are additive. The least sweet variety (aabbcc) and the sweetest (AABBCC) are bred to produce an F1 generation. All the F1 plants produce fruits of intermediate sugar content. Phenotypes are listed below:
Plants Sugar content value, relative to sweetest plant
aabbcc 40%
AABBCC 100%
F1 70%
The fruit breeder's goal is to sample a variety of sugar contents. She breeds F1 plants with one another to produce F2 progeny. For each sugar content listed below, what is the probability that an F2 plant will produce fruit with that sugar content?
a. 70%.
b. 50%.
C. 80%.
d. 100%.
Answer:
This is actually a case of additive effect that means, it doesn't matter which allele is dominant which is recessive. Here what really matter is the total number of dominant and recessive alleles.
Offspring with_
All 6 dominant allele possess 100% sugar content.
any 5 dominant alleles possess 90% sugar content.
Any 4 dominant alleles possess 80% sugar content.
Any 3 dominant alleles possess 70% sugar content.
Any 2 dominant alleles possess 60% sugar content.
Any 1 dominant allele possess 50% sugar content.
Zero dominant allele (aabbcc) possess 40% sugar content.
Hence by this concept we can easily find the percentage of sugar content of any offspring.
what is the probability that an F2 plant will produce fruit with that sugar content?
a. 70% - 17/64. (all Blue coloured offsprings)
b. 50% - 5/64. (all green cloured offsprings)
c. 80% - 15/64. (all red coloured offsprings)
d. 100% - 1/64 (single purple colored AABBCC offspring).
Parents AABBCC X aabbcc
(100%) x (40%)
F1 AaBbCc
(70%)
F1 selfing AaBbCc x AaBbCc
Possible gametes of AaBbCc are ABC, ABc, AbC, Abc, aBC, aBc, abC, and abc.
