Arctic ice retreat is threatening many species in this ecosystem. Their resources are being cut and they are needing to find new ways to survive. Do you think in your lifetime you will see drastic effects to the species in this ecosystem and why? Will that affect other ecosystems?
Answer:
no
Explanation:because they will find new ways to survive in the environment
Answer:
We are already seeing drastic effects to the ecosystem and it's wide assortment of species. Animals such as polar bears, and seals are losing their breeding and hunting grounds. Polar bears in particular are losing their ways to catch seals for food and interbreeding with grizzly bears. Fish and whales from warmer parts of the world are starting to move up north and are becoming invasive. Most importantly, since cold water from the melting ice are mixing with ocean currents, global climates and weather systems are changing course. Ultimately, in about 500 years, there could be a large Global Climatic Shift that may put us into another Ice Age.

Predict how a loss of function mutation in the p53 gene is most likely to affect the cell cycle in response to DNA damage. Justify your predictions.
Answer:
The cell cycle of cell multiplication is regulated by three types of genes, the regulatory genes that control mutations, the generic promoters of cell replication, and genes that inhibit cell replication.
The balance between these three types of gene group are what result in a good multiplication of cells without mutations or neoplastic developments.
The p53 gene is one of the genes that is considered as the guardians of the genome, since it is in charge of corroborating and regulating mutated cells, in this way it inhibits their progression in the cell cycle by putting a stop to not replicate defective genes or genes with alterations.
Explanation:
The p53 gene is one of the most altered genes seen in malignant neoplasms, since by altering our guardian of the genome many mutations overlook and more carcinogenic potential will have neoplastic tissue.
In the three groups of genes that we write, all three have a fundamental roll in the cell cycle, but in order to trigger malignant neoplasms, it is necessary that there be a continuous series of gene mutations in these three groups, it is not enough with the mutation of a single gen.

State reason(s) why ash should or should not be used in making compost
Answer:
Fireplace ashes for compost can be used to help maintain the neutral condition of the compost. It can also add nutrients to the soil. Decomposing materials in the compost pile can become somewhat acidic and wood ash can help offset this, as it's more alkaline in nature. But Adding too much ash to the pile can be detrimental to the makeup of the compost because of its alkalinity. Ashes tend to raise the soil pH, so you shouldn't use it directly on plants, especially acid-loving ones like rhododendrons, azaleas, and blueberries. Also, in high amounts, wood ash can inhibit plant growth by restricting nutrients, like iron.
explain how the products of photosynthesis are stored leaves!
Answer:
The products are stored in the form of starch because glucose is soluble
Explanation:
Answer:Although the cuticle provides important protection from excessive water loss, leaves cannot be impervious because they must also allow carbon dioxide in (to be used in photosynthesis), and oxygen out. These gases move into and out of the leaf through openings on the underside called stomata.

Which of the following depicts correct base-pairing in DNA?
A-G-A
B-A-U
C-C-T
D-T-A
Answer:
D. T- A
Explanation:
In dsDNA the bases in the two strands are paired through hydrogen bonds forming base pairs (bp). Adenine forms two H-bonds with thymine from opposite strand and vice-versa. Similarly, guanine is bonded with cytosine with three H-bonds. As a result, always a purine comes opposite to a pyrimidine.

Which was not produced by volcanic outgassing?
O A. Oxygen
O B. Sulfur
O C. Water vapor
O D. Carbon dioxide
Answer: A. Oxygen
Explanation:
The component that was not produced by volcanic outgassing is oxygen, while the rest of all the released during the process of a volcanic eruption.
What do you mean by Volcanic outgassing?Volcanic outgassing may be defined as an eruption that releases a gas that was dissolved, trapped, frozen, or absorbed in some material.
Volcanic eruption transfers various gases from the interior of the Earth to the atmosphere leading to outgassing which includes water vapor, carbon dioxide, and sulfur.
Therefore, the component that was not produced by volcanic outgassing is oxygen, while the rest of all the released during the process of a volcanic eruption.

A)Limiting Factors prevent populations in ecosystems form growing any larger. If any of the limiting factors change, animal and plant populations change, too.
B)Limiting factors do not prevent populations in ecosystems from growing any larger. If any of the limiting factors change, animal and plant populations do not change, too.
C)Limiting factors can never impact ecosystems.
D)As biodiversity of an ecosystem increases, the ability to withstand environmental stress due to the loss of a single species or group also increases, improving the sustainability of the ecosystem.
Answer:
limiting factors like the availability of food, water, shelter and space can change animal and plant populations. Other limiting factors, like competition for resources, predation and disease can also impact populations. ... Sometimes a population will grow too large for the environment to support.

A new type of fish has been discovered. It has vibration receptors on its snout and virtually nonexistent eyes. Based on these characteristics, in which part of the ocean is this fish most likely found?
If a fish has vibration receptors on its snout and virtually nonexistent eyes, these characteristics are found in the fish which leaves at the bottom of the ocean.
What is the use of receptors on fish?It is found under the skin, the lateral line made of sensory receptors known as neuromasts. While the cilia in the neuromasts vibrate, the fish can sense.
The lateral line may likewise feel and observe water pressure (depth), currents, objects, prey, and predator movements, this senses increase the chance for the survival of the fish.
Food and lure that is living and moving would be simple for fish to detect as it has a smell, sound and vibration.
Therefore, with vibration receptors, at the bottom of the ocean, this kind of fish generally found.

Why we should be concerned about the increase in amount of the green house gases in the atmosphere?
Answer:
We should be concerned about the amount of green house gases released into the atmosphere because the more gases are released, the more they accumulate in the atmosphere and trap heat, which contributes to global warming, which is causing massive changes in our environment all around the world.
