Answer:
First off it would 'attack' the immune system, the virus would attach itself to healthy cells, then continue to move through your body - your bodies first response is always going to be your immune system - it's going to fight the foreign visitor aka the virus. The virus will then move down towards your respiratory system. And given the symptoms that you may experience whilst your body is fighting the virus is how it may work with other systems (these two being the main ones) for example; diarrhea, nausea/vomiting, headaches, sore throat, etc. And it will also depend on the patients history. Hope this helps.

A pair of identical twins develop leukemias, where immature white blood cells proliferate uncontrollably. In each case, the cancer cells analyzed from identical twins displayed an identical chromosomal mutation and this critical mutation was not found in the twins normal cells. The twins developed leukemia at different times in their lives. What is the best explanation for the origin of this chromosomal mutation
Answer:
The chromosomal rearrangement resulted from a rare somatic mutational event that occurred in utero
Explanation:
Leukemia is a progressive type of cancer where immature white blood cells (leukocytes) proliferate uncontrollably. Next-generation sequencing (NGS) technologies have shown that somatic mutations are relatively common in different types of leukemia such as, for example, acute myeloid leukemia (AML). Moreover, identical twins are developed from one fertilized egg (ovum) that splits and develops into two identical individuals that share all of their genes (i.e., they have exactly the same genetic information). In this case, it is expected that leukemogenesis was initiated in the utero by the occurrence of a chromosomal rearrangement and proceeded early during development as distinct clonalities. In addition, the fact that identical twins developed leukemia at different times in their lives also indicates that this malignancy wasn't caused by only one mutation, but instead it was triggered by multiple mutational events (i.e., leukemia is a multistep cancer caused by secondary genetic changes).

The assistant strength and conditioning coach for a small college works with athletes in all sports. With only two lifting platforms and four squat racks, space is limited and training sessions are chaotic. Morning and early afternoon hours are the low-activity times of the day. At 3 p.m., student-athletes fill the room beyond capacity, making individualized instruction and room supervision difficult. What steps should the assistant strength and conditioning coach take to properly address these concerns?
Answer:
The solution to these question can be defined as follows:
Explanation:
Both students including athletes who undertake the program can be assigned slots relating to some period the classical or athlete should report completing their practice. The slots aren't allowed to continue.
They have a structured exercise template for each person, that helps for easy student or athlete monitoring, based on their skill.
This can be encouraged to students and teachers to attend daily and midday meetings.
The MAP kinase pathway is activated by ligand binding to a transmembrane receptor, which switches Ras on via GEF (Guanine nucleotide Exchange Factor) that counteracts GAP (GTPase Activating Protein) activity. Ras-GTP in turn activates the downstream signaling intermediates (kinases), which are activated by sequential phosphorylation. Which drug CANNOT be used to target cancer cells that have elevated receptor activation
Answer:
Inhibitor molecules that interfere with GAP activity
Explanation:
The mitogen-activated protein kinase (MAPK) is a pathway composed of proteins that amplify and integrate signals from receptors localized on the surface of cells and trigger the transcription of specific genes in the nucleus of the cell. In eukaryotic organisms, the MAPK pathway is known to control critical cellular processes such as, for example, cell proliferation, cell differentiation, cell death, etc. RAS proteins are GTPases localized to the plasma membrane involved in MAPK signaling. Moreover, the GTPase activating proteins such as RasGAP (Ras GTPase activating protein) regulate Ras-GTP bound by promoting GTP hydrolysis. It has been shown that RasGAP expression is down-regulated in different types of cancer. In this regard, it has been proposed that the interference of GAP activity should result in an enhanced Ras protein activation in cancer cells, thereby initiating tumorigenesis by inducing, for example, uncontrolled cell proliferation.

In genetics, what does a genotype of Hh signify?
Answer:
In genetics, Hh means a heterozygote.
Explanation:
Usually, in genetics, H would be the dominant, and h would be the recessive trait. HH is usually dominant, and hh would be recessive. So, Hh would mean a heterozygote. In a heterozygote, this would mean that the recessive trait is in the genotype, but the dominant trait would still take over. This also means that sometimes, the recessive trait can be shown along with the dominant. This can be possible through co-dominance, and incomplete dominance. Hope this helps!
Answer:
CORRECT (SELECTED)
Heterozygous; one dominant allele and one recessive allele
Explanation:
A heterozygous individual (Hh), also known as a carrier, has a genotype with one dominant allele (H) and one recessive allele (h).

Read the passage. Then, use what you know about how populations affect one another during ecological succession to explain what happens on an empty lot.
Imagine what happens in an empty lot that has been cleared of all living things. As in a garden that is no longer planted, only soil remains. Weeds begin to grow in the soil. At first, only plants that need full sun to sprout grow there. But over time, these plants grow taller and shade the ground. Then, a different kind of plant begins to grow there, one that grows only in shady areas. Eventually, the lot is covered in mostly plants that sprout in shade.

A population of drosophila flies lives in a forest and has variation in their egg-laying behavior. The majority of the flies have the trait of laying eggs in the rotting bark of trees. A small percentage of the flies have the trait of laying eggs in bark that is dampened by sap. The drosophila population moves into a new forested area that is drier, where rotting bark is harder to find than sap. How will the population change over several generations
Answer:
It will contain a larger proportion of flies that lay eggs in sap because the trait results in a higher chance of reproducing successfully and passing on the gene
Explanation:
Over the years the population of flies that lays egg in the rotten bark will reduce this is because of the low chance of reproducing and there will be an increase in the population of flies that lays egg in the sap because the flies have a higher chance of reproducing successfully leading to an increase in the population and the ability of the gene to be passed on successfully to their offspring in next generation.

The power in our homes and buildings cycles at a frequency of 60Hz. If someone accidentally dropped a power line into a holding tank for frogs their muscles would immediately become stiff. This is because the high frequency stimuli is causing:_______
a. rigor mortis.
b. tetanus.
c. fatigue.
Answer:
a. rigor mortis.
Explanation:
Electricity refers to the power generated from various power sources or power plants such as hydroelectric, wind turbine, solar, nuclear, etc.
Generally, the power supplied to homes, offices and buildings cycles at a frequency of 60 Hertz or 50 Hertz depending on the parameters chosen in countries. If a power line is dropped accidentally into a holding tank for frogs, it would immediately cause their muscles to become stiff due to the current flowing through the power line i.e because the power line is energized and has electrons moving across its terminals. This stiffness is because the high frequency stimuli is causing rigor mortis.
what is convection heat
Heat convection is a mode of heat transfer by the mass motion of a fluid such as air. Heat convection occurs to the surface of an object where the surrounding fluid of object is heated and moved energy away from the source of heat.

Lab: Interdependence of Organisms
Interdependence Of Organisms
Question Being Answered:
How can the presence of one species benefit another in the same ecosystem?
Hypothesis:
If plants grow in soil that contains worms the plants growth will be greater because worms are able to help decompose organic matter and help distribute it through the soil in a form plants are able to use.
Process Of Lab:
In this lab you will grow two different groups of plants. Group A is considered the experimental group which will grow in soil with worms, Group B is considered the control group which will grow in soil without worms. After the plants grow you have to measure the plant growth for both groups and compare them.
Independent & Dependent
Independent Variable: Presence Of Worms
Dependent Variable: Plant Growth
Safety Procedure
Be sure to follow the safety procedure which means to
Wear safety goggles and lab gown while doing the experiment
Keep lab behavior purposeful
Look over the soil contents and make sure to follow warnings provided on any equipment
Wash hands and lab equipment once done with experiment
Treat living organisms with respect and provide proper care
Report any accidents that happen in the lab to your teacher
Lab Procedure
Step 1: Gather Materials
Two trays that are 10 cm 4’ deep
Potting soil
Lima bean seeds which need to be soaked overnight
Location with sunlight or growth lights
Worms
Graduated cylinder
Water
Black marker
Ruler with metric markings
Step 2: Prepare Two Trays Of Lima Bean Plants
Label the trays Control Group and Experimental Group
Add approximately 6-7 cm of soil to each tray
Plant 6 lima bean seeds in each tray being 2 cm deep and label the plants 1-6
Step 3: Give The Plants Water And Light During Sprouting Time
Keep the environments for both groups identical
Water all the plants following the watering schedule that was recommended on the seed packaging
Use the graduated cylinder to ensure the same amount of water is being given to both groups
Make sure all plants get the same amount of light
Step 4: Measure The Heights Of The Plants At The End Of Week 1
Measure the height of all twelve plants to the nearest cm. If a plant dies mark an x on the data table for that plant and write it in your notes
Use a calculator to find the average heights of the living plants in each groups
Calculate the difference in those average heights by subtracting the average height of the plants in the control group. Use this difference as a basis for comparison
Record measurement observations in your notes and the health of the plants such as leaf colors and size, wilting, unusual growth, brown spots, and any other marks you see
Step 5: Add Six Worms To The Soil Of The Experimental Group Of Plants
Write descriptive notes about the condition of the worms in your notes
Step 6: Measure The Heights Of The Plants At The End Of The Week 3
Repeat step 4
Step 7: Measure The Heights Of The Plants At The End Of Week 5
Repeat step 4
Step 8: Check The Health Of The Worms At The End Of The Study
Are the worms still alive?
Do they all seem healthy?
Have they changed in any way? If so list the ways changed
Are there any new worms
Be sure to write descriptive notes about their conditions in your notes
