Recently, state forests and parks like Yellowstone National Park which contain varieties of flowering trees and shrubs, have started to erect signs that state, Take nothing but pictures, leave nothing but footprints.
Which argument BEST supports why these signs are being placed in state forests and parks?
A
Flowering tree and shrub ecosystems can never fully recover once humans have adversely affected them because organisms in these ecosystems are nonrenewable.
B
Removal of the flowering trees and shrubs will have a direct impact on the ecosystem by increasing the stability.
C
Humans can cause damage to the stability of ecosystems by removing the flowering trees and shrubs.
D
Flowering trees and shrubs make the state forest and parks more attractive and increase the revenue for the parks.
Answer: C.
Explanation:
The signs are placed because humans can cause damage to the stability of ecosystems by removing the flowering trees and shrubs.
Ecosystems are self sustaining units in which there is an exchange of materials and energy within itself. There is need for sustainability in ecosystems to ensure that they continue to survive and ultimately to preserve biodiversity.
The sign; "take nothing but pictures, leave nothing but footprints" placed on state forests and parks like Yellowstone National Park which contain varieties of flowering trees and shrubs are there because humans can cause damage to the stability of ecosystems by removing the flowering trees and shrubs.

Write your question here (Keep it simple and clear to get the best answer) what name iz give to the female part of the flower?
Answer:
The female part of the flower is called gynoecium or pistil
Explanation:
The female part of a flower is called the gynoecium or pistil. The pistil is located in the center of the flower and consists of three parts: the stigma, style, and ovary.
The stigma is a sticky knob-like structure located at the top of the pistil. It is covered with a sticky substance so pollen grains will stick to it. It is attached to the long, tubelike structure called the style.
The style is a long long tubelike structure which connects the stigma to the ovary. The style provides the pathway through which the pollen grains will travel to the ovary in order to fertilize the eggs or ovule
The ovary is the enlarged portion of the pistil found at the base of the pistil. It contains the eggs or ovules. After fertilization, the ovary develops into the fruit and the ovules become seeds. Based on where the ovary of a plant is located, a plant can be classified as having a superior ovary, an inferior ovary or a half-inferior ovary.
Among the newly-discovered small noncoding RNAs, one type reestablishes methylation patterns during gamete formation and blocks expression of some transposons. What are these types of RNA called
Answer:
piwi-interacting RNAs (piwi-RNAs)
Explanation:
The piwi-interacting RNAs (piRNAs) are small non-coding RNAs (from 21 to 31 nucleotides) that are abundantly expressed in the animal germline in order to control the expression of target sequences. The piRNAs associate with PIWI proteins from the Argonaute family (AGO) to form an effector complex that binds to complementary target DNA/RNA sequences. These small ncRNAs target Transposable Element (TE) transcripts to suppress TE expression and thus maintain genome integrity. The piRNAs can also guide epigenetic remodeling complexes that suppress gene expression by methylation of target DNA sequences in the nucleus.

Staphylococcus aureus, or staph, is a bacteria that is commonly found in the nose and on the skin of humans. While it is typically not harmful to humans, it is sometimes able to enter the body through an injury or broken skin, and get into the bloodstream. When this happens, it can cause a serious infection called sepsis. Sepsis can cause an individual to go into shock and bodily organs to stop functioning. Symptoms of sepsis include inflammation, fever or hypothermia, increased heart rate, and rapid breathing.
A microscopic image of staphylococcus aureus is shown.
Which immune system component initially results in the inflammation and responds quickly when Staphylococcus aureus enters the bloodstream?
complement system
phagocytes
Langerhans cells
B lymphocytes

7. Which molecule is light energy temporarily stored in before being used to make glucose?
Answer:
The Calvin cycle uses CO2 and the energy temporarily stored in ATP and NADPH to make the sugar glucose. Photosynthesis is a two stage process. As is depicted here, the energy from sunlight is needed to start photosynthesis. The initial stage is called the light reactions as they occur only in the presence of light

Which cell would have MOST trouble maintaining homeostasis?
A. Cell A
B. Cell B
C. Cell C
The cell that would have the most trouble maintaining homeostasis is cell A. The correct option is a.
What is homeostasis?Any self-regulating process, such as homeostasis, helps an organism retain stability while responding to environmental factors that are favorable for its survival. If homeostasis is effective, life continues; if it is not, the organism perishes or suffers a catastrophe.
There are three cells in the given which are of different sizes' cell a is 1 cm cell 2 is 2 cm and cell 3 is 3 cm from each side.
Cell A would have the most towel in maintaining homeostasis, says because it is small and growing is one of the terms needed for maintaining homeostasis. If the organism is small it would have difficulty, then the organism is big it would easily maintain the homeostasis of his body.
Therefore, the correct option is a, cell A.

Complete the following Punnett square, show the genotypes produced by the the offspring of an agouti x chinchilla cross, and an albino using the following alleles: A=agouti, C=chinchilla, a=albino, A is dominant over C and a, C is dominant over a. Assume the agouti rabbit is female. Place your answers in their correct spots on the grid. Hint: complete the agouti with chinchilla cross first.
Answer:
Now there we go! That's the complete question. But anyway, here's your answer:
C C
A AC AC
A AC AC
Basically, what this Punnett Square means is that all of the offsprings will be Agouti, due to Agouti being the dominant trait. However, the genotype of the offsprings will be heterozygous since all offsprings also carry the allele C as well.
