Ecological succession is initiated by changes that occur in the environment such as a disturbance; option B.
What is ecological succession?Ecological succession is the process by which the species present in a given habitat gradually change over with the parent species of organisms being replaced with new species of organisms until a stable species is established.
Ecological succession is initiated by changes that occur in the habitat.
These changes include biotic factors such as disease, and competition, and climatic factors such as wind, fire, soil erosion, and natural disasters include climatic factors.

transcribe 3’ TACCGTTAGGATATC 5’
Based on the sequence, the given sequence is the non-transcribed strand of DNA. I wrote a sequence of double-stranded DNA. The top strand indicates the transcription start site ATG. In messenger RNA, T or thymidine is replaced by U or uracil.
You can look up the codon table to give all possible amino acids where ATG, which encodes methionine, can be the first amino acid.
5'-A T G G G A A AT C A T C G G T G A-3'
3’-T A C C C T T T A G T A G C C A C T-5’
All mRNAs are read in the 5'-3' direction and polypeptide chains are synthesized from the amino terminus to the carboxy terminus. Each amino acid is specified by its three base codons in the mRNA, according to the nearly universal genetic code. The main enzyme involved in transcription is RNA polymerase, which uses a single-stranded DNA template to synthesize a complementary strand of RNA.

Answer:
would this help The six largest Hawaiian Islands—the Big Island, Maui, Lanai, Molokai, Oahu, and Kauai—form a chain of islands running to the northwest? The islands appear in this pattern for a specific reason: They were formed one after the other as a tectonic plate, the Pacific Plate, slid over a plume of magma—molten rock—puncturing Earth’s crust. These magma plumes aren’t small—they can extend hundreds of kilometers below the Earth’s surface.

7. How do mutations in DNA sequences affect a species?
Answer:
For mutations to affect an organism's descendants, they must: 1) occur in cells that produce the next generation, and 2) affect the hereditary material. Ultimately, the interplay between inherited mutations and environmental pressures generates diversity among species
27. In one part the ________ cycle, organic matter is buried underground andconverted to peat, coal, oil, or gas deposits.A. carbonB. nitrogenC. phosphorous
During the carbon cycle, organic matter can be used in multiple ways by different organisms, although, this chemical compound also can be buried underground and converted into peat, coal, oil, or gas deposits. This is possible due to organisms can store this material in their structures to grow, and eventually, when they decay, for example, when a tree or an animal dies, it begins to form part of the soil in which they were before. This is the reason why currently we can extract oil from underground sinks, because of those biggest organisms that lived millions of years ago, such as the dinosaurs and ancient plants.
Having this clear, we can say that the correct answer is the first one.
We can see the carbon cycle in this licensed image.

a home made protocol for animal tissue DNA extraction?
DNA (deoxyribonucleic acid) is the hereditary material in almost all living organisms. Most DNA is located in the nucleus.
For extraction of DNA we need 500 ml water,91% Isopropyl Alcohol (rubbing alcohol),Dishwashing liquid, Salt, Food coloring (dark colors recommended),3 clear plastic cups
Steps include Pour 500ml water in a plastic cup
2. Add one tablespoon of salt to the water
3.dissolved the salt completely
Transfer 2 tablespoons of salt water in a clear plastic cup
2. Vigorously trill the salt water
3. Spit salt water back into the same cup
When you trill the salt water, cheek cells will come out. Add 1ml of clear dishwashing soap to the salt .It will break open the cheek cells and their nuclei walls and this causes the DNA to be released into the salt water.
1. Pour 100 ml isopropyl alcohol plastic cup.
2. Add 3 drops of food coloring, and isopropyl alcohol in a separate clear plastic cup.
2. Add 3 drops of food coloring, mix them well
DNA is insoluble in isopropyl alcohol so it will promotes the clustering of the DNA, making them visible.

The cells that make up skeletal muscular tissue are somewhat unique for having:
O cell walls instead of cell membranes.
O especially porous cell membranes.
O no mitochondria.
O cells with multiple nuclei.
The cells that make up skeletal muscular tissue are somewhat unique for having cell walls instead of cell membranes and is denoted as option A.
What is Cell wall?This is mostly found in the outer region of the cell membrane and is a rigid, semi-permeable protective layer which consists of lipids, cellulose and polysaccharides needed for its functions.
The cell wall is mostly found in plants but at the same time they are present in some cells of the body such as that of the skeletal muscular tissue due to the rigorous activities being performed by them.
This helps to maintain the structural integrity of the cells and ensures that movement is easily done which is the reason why they are present instead of cell membranes hence option A is correct.

The ice age or serious wintertime term is caused by the variety within the time and concentration of Light. The light coming from the sun includes an exceptionally viable nature on earth's climate and by and large environment of the surface of the soil.
Andean-Saharan ice age (460 to 430 million a long time back)- It caused the mass termination of creatures, and after a brief term of time. The plants secured most of the surface of the soil. Because it too said that due to this tall number of plants another ice age was caused.
Karoo ice age (360 to 260 million years ago): karoo ice age worked much just like the same as that we are living in now. Antarctica solidifies over (14 million a long time back): Right now, we are living in this ice age. As the shafts of the soil are secured by ice caps.

TRUE OR FALSE??
Answer: It is True
Explanation:
In your own words, what was the purpose of the lab?
True or False: Earth contains many different cycles thatinteract with each other and they move through Earth'sdifferent spheres.
Earth's ecosystem can be divided into 4 spheres, which are the atmosphere, the biosphere, the hydrosphere, and the geosphere. These spheres interact with each other and a change in one of them may cause a change in the other three spheres.
Within the ecosystem, the substances, such as water, carbon, oxygen, and nitrogen, undergo biochemical cycles. Through this cycle, the substances revolve through all spheres and are distributed throughout the whole ecosystem.
The statement is therefore TRUE.

The Loch Raven Reservoir supports a variety of organisms at all times of the year. There is an algal bloom this year. How would the environment be expected to change?
It is expected that the algal bloom in the Loch Raven Reservoir would change by decreasing the amount of available biomass.
What is the direct consequence of an algal bloom?The direct consequence of an algal bloom is an increase in the amount of available oxygen in the aquatic system and a drastic reduction in the light that enters into this ecosystem, which reduces the amount of biomass because plants are unable to produce photosynthesis.
Therefore, we can conclude that the consequence of an algal bloom is a decrease in the biomass that supports the trophic chain in this aquatic ecosystem.

Answer: Muscle contraction occurs when the thin actin and thick myosin filaments slide past each other. It is generally assumed that this process is driven by cross-bridges which extend from the myosin filaments and cyclically interact with the actin filaments as ATP is hydrolysed.
Explanation: and this is what happens: The sliding of protein filaments is responsible for muscle contraction. When a motor neuron stimulates a muscle fiber, overlapping thick and thin filaments slide along one another and sarcomeres shorten. The combined shortening of many sarcomeres in many muscle fibers results in contraction of the whole muscle.

what is Geostrophic current?
At the point when the water is pushed to the right it frames the slope we describe previously. In this way, when water is moved along by the breeze it needs to be gone to one side by the Coriolis force (in the northern half of the globe) yet it should battle against gravity (attempting to climb the slope of water framed by Ekman transport). A balance is met between the Coriolis and the gravity (pressure inclination force). This balance delivers a fair stream called a Geostrophic current.
