1. Summarize the six ways the loss of Arctic ice is affecting everyone.
six ways are temperature,coastal communities,food,shipping,wildlife,permafrost
Answer:
Explanation:
Artic Ice are melting due to change in the climatic system as a result of global warming. The active increase in human activity resulting in global warming will continually perpetuate the decrease in artic Ice.
Artic heat help to balance temperature or heat on the earth surface by reflecting heat back into the environment. When the artic Ice is reduced, the amount of heat reflected is also reduces.
Coastal community - a continuous rise in ocean level can lead to flooding which will affect the coastal community surrounding the ocean. An the ocean has been incredible gradually over the pass decades.
Food - Reduction in the artic Ice car Lea to increase heat affect crop growth through damage by heat stresses leading to an increase price rate of food.
Meltng of Ice increase the shipping routes causing more harm through ship wrek.
Melting of Ice can leave to loss of animals that depends on it for survival.
Permafrost occurs when the ground is permanently block or frozen leading to accumulation of methane gases that causes global warming.
A study from the National Institutes of Health states that the human body contains trillions of microorganisms that make up 1% to 3% of the body's mass. Use this information to estimate the average mass of a microorganism.
Answer:
If the mass of the human body is 60 kg so the average mass of microorganism is 1.2 kg.
Explanation:
If we suppose the mass of human body is 60 kg and we know the percentage that is 1 to 3% so we will take the average microorganism mass of which is 2%. So by doing multiplication of 60 with 2 and then divided by 100, we get 1.2 kg. The reason for dividing by 100 is that the average mass present in percentage form so for converting the percentage into standard form we have to divide it by 100. So we conclude that in every human with a mass of 60 kg have 1.2 kg microbes present in their body.

Explain that different sequences of amino acids give different shapes to protein molecules
Explanation:
The sequence of amino acids in the chain determines how the chain will fold up to make the protein, so different proteins have different three-dimensional shapes. ... This is because proteins form attachments and interact with many other molecules and structures inside organisms.
You are running an experiment to study seed germination and accidentally left a dish of seeds covered with a little water in a totally dark room. When you return a few days later, you notice that the seeds have sprouted long roots and long shoots. What was the source of most of the matter that makes up these roots and shoots?A. oxygen in the airB. carbon dioxide in the airC. water in the dishD. glucose in the seed
Answer:
D. glucose in the seed
Explanation:
Plants generally make their food through the process of photosynthesis in the presence of sunlight by utilizing carbon-dioxide and water and produces oxygen and carbohydrate.
But due to the absence of sunlight, plant will be unable to use carbon dioxide and water for photosynthesis and oxygen is a by-product.
So the reason of seed germination is the presence of glucose in the seed. Seeds generally germinate through the process of inhibition, that require uptake of water. Glucose works as energy source in humans and plants as well. sugar or glucose allow the seed to utilize the water and help foster its growth.
Hence, the correct option is D. glucose in the seed.
Based on the objective you should feel comfortable calculating expected genotype frequencies when given observed allele frequencies. You should also be able to compare expected genotype frequencies from HWE to observed frequencies and determine if evolution is occurring. Here's a sample problem. You can do this without a calculator! Let's take the noob gene, a gene with two known alleles that determines feather color in the eastern lark. The two alleles, let's call them delta and gamma, can be sequenced. In fact, looking at a population in southern GA, you discover that 60% of the alleles in the population are the delta allele. So question 1, what is the percentage of the gamma allele in the population
Answer:
40% is the percentage of the gamma allele in the population.
Explanation:
Available data:
Two alleles, delta and gamma60% of the alleles in the southern GA population are the delta alleleWhat is the percentage of the gamma allele in the population?
According to Hardy-Weinberg, the allelic frequencies in a locus are represented as p and q, referring to the allelic dominant or recessive forms. The genotypic frequencies after one generation are p² (Homozygous dominant), 2pq (Heterozygous), q² (Homozygous recessive). Populations in H-W equilibrium will get the same allelic frequencies generation after generation. The sum of these allelic frequencies equals 1, this is p + q = 1.
In the same way, the sum of genotypic frequencies equals 1, this is
p² + 2pq + q² = 1
Being
p the dominant allelic frequency, q the recessive allelic frequency, p² the homozygous dominant genotypic frequency q² the homozygous recessive genotypic frequency 2pq the heterozygous genotypic frequencyIf the percentage of delta allele in a population is 60%, this means that its frequency is 0.6. By clearing the equation p + q = 1, we can calculate the gamma allele frequency. This is:
p + q = 1
0.6 + q = 1
q = 1 - 0.6
q = 0.4
Then the percentage of gamma allele in the population is 40%.
We can also think about it like this:
If the sum of the allelic frequencies equals 1, then 1 is 100% of the allelic frequencies. And if the percentage of delta allele in a population is 60%, then 40% is the percentage of gamma allele.
What cell type are involved in the secretion thyroglobulin ?
By thyroid epithelial cells and secreted into the lumen of the follicle - colloid is essentially a pool of thyroglobulin.
What is Thyroglobulin?The amount of thyroglobulin in a sample of your blood is measured by a thyroglobulin test. Your thyroid produces a protein called thyroglobulin. A little gland in your neck with a butterfly form is your thyroid.
It produces hormones that regulate a variety of bodily functions, such as your heart rate and how quickly you burn off calories from food.
One kind of test for tumor markers is the thyroglobulin test. In reaction to cancer in your body, cancer cells and/or normal cells produce molecules known as tumor markers. Small levels of thyroglobulin are typically released into your bloodstream by your thyroid.
Therefore, By thyroid epithelial cells and secreted into the lumen of the follicle - colloid is essentially a pool of thyroglobulin.

13. Ranchers lobbied the government to eradicate wolves from Yellowstone National Park. Five years later the deer population had increased fivefold. The following winter 70% of the deer starved to death. Explain why this was bound to happen.
Answer: The overgrowth in deer population led to a food shortage.
Explanation:
Since the eradication of the wolves, the deer had no predator to keep their total population in check. Due to the vast amount of deer the food in the area was being eaten at a faster rate. Most of the deer died do to their environment not being capable of feeding that many deer.

Diffusion is a passive process that accounts for the movement of respiratory gases across the capillary membranes of alveoli.
True
False
Answer:
True
Explanation:
Diffusion is a passive process (no energy required) in which the substance such as liquid and gases moves from an area of high concentration to an area of low concentration.
During respiration, carbon dioxide diffuses from the blood into the alveoli and oxygen diffuses from alveoli to blood across the respiratory membrane. The partial pressure of oxygen is low in the blood of the pulmonary capillaries and high in the alveoli. so diffusion allow movement of oxygen across the respiratory membrane from the alveoli into the blood.
Hence, the given statement is true.

Answer:
The medullary cavities are found deep in the diaphyses of long medullary cavities bones and are filled with yellow marrow in the adult.
Osteocytes maintain contact with neighboring osteocytes in adjacent lamellae via dendrite-like extensions through canaliculi.
Filled with osteocytes, which are osteoblasts encased in matrix, lacunae are found between layers of concentric lamellae.
Located in the middle of osteons, the central canal contain the blood vessels, and nervous supply of the compact bones
Explanation:
- The medullary cavities are central cavities in the bones. In adults, these cavities are filled with yellow marrow (adipose tissue).
- The canaliculi are small protoplasmic projections between the lacunae of ossified bones.
- The astrocytes are the most common type of bone cell.
- The lacunae are spaces where osteocytes are located in the mature bones
- The central canal provides nourishment to the osteocytes which collectively form the osteon.
you have selected the following prediction to test: Previously thinned forests will have higher tree survival than adjacent forests that were not thinned. Now you need to define the key variables that you will use to test this prediction. For the following variables, sort them as independent variables, dependent variables, or variables that should be controlled (held constant)1. thinning or no thinning before the fire elevation of the site 2. dominant tree species 3. tree survival rate after the fire A. Independent variableB. Dependent variable C. Controlled variable
Answer:
A. Independent variable 2. dominant tree species
B. Dependent variable 3. tree survival rate after the fire
C. Controlled variable 1. thinning or no thinning before the fire elevation of the site
Explanation:
A. An independent variable doesn't undergo changes during the experiment because it is not conditioned by other variables in the experiment. In this example, dominant tree species represent a variable that is independent of the experiment itself.
B. A dependent variable is those that you need to measure and depends on the other factors in the experiment. In this example, tree survival is dependent on the factors that affect the results (i.e. humidity in the trees, presence of resinous material in the trees that are non-combustible, etc.)
C. A controlled variable is those that we use to observe an expected outcome in the experiment and therefore it is used to compare with the test group. In this case, thinning or no thinning are used as positive and negative controls, respectively, because they enable their comparison with the test group in the experiment.

Predict which one of the following organisms will have the highest percentage of unsaturated fatty acid chains in their membranes: Group of answer choices thermophilic bacteria desert iguana humans antarctic fish
Answer:
Humans
Explanation:
Humans are bigger than most beings and some people are extremely obese.
The organisms that have the highest percentage of unsaturated fatty acid chains in their membranes are ANTARCTIC FISH.
Unsaturated fatty acid chains have one or more double bonds, while saturated fatty acid chains do not contain any double bonds.When the temperature decreases, the composition of the phospholipids bilayer membrane becomes more unsaturated to be able to maintain different properties such as homeoviscosity.In consequence, membrane lipids exhibit the highest percentage of unsaturated fatty acid chains during cold acclimation.In conclusion, the organisms that have the highest percentage of unsaturated fatty acid chains in their membranes are ANTARCTIC FISH.

hope this helped!
During hybridization, DNA strands bind together. The correct option is A.
The process of joining two complementary strands of DNA from various sources to create a double-stranded molecule is referred to as hybridization.
The complementary DNA strands join together during this phase and create strong hydrogen bonds between their corresponding base pairs. Adenine (A) and thymine (T) and guanine (G) and cytosine (C) couple up specifically to form this interaction.
Numerous molecular biology procedures, including DNA hybridization tests, polymerase chain reaction (PCR), and DNA sequencing, frequently employ hybridization.
Hybridization enables the identification and amplification of particular DNA sequences as well as the analysis of genetic data by allowing the complimentary strands to come together.
