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.

Answer:

°•°

Explanation:

1.fallopian tube

2.an unborn or unhatched offspring in the process of development, in particular a human offspring during the period from approximately the second to the eighth week after fertilization (after which it is usually termed a fetus)

3.First, the zygote becomes a solid ball of cells. Then it becomes a hollow ball of cells called a blastocyst. Inside the uterus, the blastocyst implants in the wall of the uterus, where it develops into an embryo attached to a placenta and surrounded by fluid-filled membranes.

4.Eggs live in ovaries, and the hormones that control your menstrual cycle cause a few eggs to mature every month. When your egg is mature, it means it's ready to be fertilized by a sperm cell. These hormones also make the lining of your uterus thick and spongy, which gets your body ready for pregnancy.

5.The fertilized egg attaches to the lining of the uterus. The placenta then develops. The placenta transfers nutrition and oxygen to the fetus from mother. If the egg does not become fertilized, the lining of the uterus (endometrium) is shed during menstruation.

6.The egg cell travels down the fallopian tube into the uterus. The moment the egg cell leaves the ovary is called ovulation. Once a girl has had her first monthly period, ovulation usually occurs once a month

7.The average menstrual cycle is 28 days long. Cycles can range anywhere from 21 to 35 days in adults and from 21 to 45 days in young teens. The rise and fall of levels of hormones during the month control the menstrual cycle.

What is a limiting factor??

Answers

Answer:

look below

Explanation:

A limiting factor is a variable of a system that causes a noticeable change in output or another measure of a type of system. The limiting factor is in a pyramid shape of organisms going up from the producers to consumers and so on. A factor not limiting over a certain domain of starting conditions may yet be limiting over another domain of starting conditions, including that of the factor.

Which of the following would be an example of positive feedback? thanks!



Select one:


Shivering by the muscles when temperature drops.


The attraction of platelets when a wound occurs.


Sweating due to an increase in body temperature.


The reduction of hormone production during pregnancy.

Answers

Answer:

2

Explanation:

The attraction of platelets when a wound occurs indicates a positive feedback. The correct option is B.

What is feedback mechanism?

The feedback mechanism is the body's mechanism for keeping hormone levels within desired limits.

The feedback mechanism is activated by an increase or decrease in hormone levels. The body has two types of feedback mechanisms: positive feedback mechanisms and negative feedback mechanisms.

Positive feedback loops and negative feedback loops are the two types of feedback loops.

Positive feedback increases system output, causing growth or decline. Negative feedback dampens output and helps to keep the system stable around an equilibrium point.

Platelet plug formation is thought to be a positive feedback process because ADP and VWF levels rise as more platelets activate to form the plug.

Thus, the correct option is B.

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

Answers

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.

Transcriptional termination by RNA polymerase is favored when tryptophan levels are low (1) / high (2), because the low levels (3) / abundance (4) of charged Trp-tRNATrp causes the ribosome to quickly synthesize the leader polypeptide (5) / stall at the pair of Trp codons (6). This termination (7) / elongation (8) structure forms because the 3-4 stem loop (9) / the ribosome (10) allows region 2 to pair with region 3.
a. 1,3,6,8,9.
b. 2,3,5,8,9.
c. 1,4,6,7,10.
d. 2.4,5,8,10.
e. 2.4.5.7.9.

Answers

Answer:

The answer is "Choice e".

Explanation:

The additional Trp Operon function is gene expression attenuation. If tryptophan levels are high, RNA Polymerase endings of glutamate operone are favoured, since the excess of Trp-tRNATrp load causes rna to rapidly synthesise the lead polyprotein and region iii base pairs with cluster 4 and creates stepping chain structures which signal mrna cessation. Rest both options are wrong in regards to the glutamate operon amplification transmission termination mechanism.

Answers

Answer:

The correct answer is D)

Decades ago, the U.S. government mandated that they and other Alaskan natives abandon a nomadic life based on hunting and fishing for sedentism.

Explanation:

Sedentism is simply the practice of settling in one geographical location for a long time.

Many governments encourage this to ensure that agricultural systems become developed and more sustainable as was the case in Alaska.

Other governments in some part of the world are also in support albeit for a different reason such as security of lives and property.

Answers

Answer:

It provides ATP.

Explanation:

It is adaptive for the larger host cell to keep the engulfed cell alive, instead of digesting it as food because the engulfed cell provides energy in the form of adenosine triphosphate (ATP) to the host cell. The larger host cell is able to survive in anaerobic conditions with the help of engulfed cell alive so that's why we can conclude that the larger host cell keep the engulfed cell alive instead of killing it and used as a food source.

From fossil evidence, you know two species shared a common ancestor approximately 50 million years ago. In comparing a known neutral sequence between rats and mouse, you found 92 base differences in 1000bp. From this information, which of the following values is closest to what you would predict the mutation rate to be?
a. 1 x 10-9
b. 4 x 10-9
c. 2 x 10-9
d. 5 x 10-9
e. 5 x 10-8
f. 8 x 10-9

Answers

Answer:

Option c ([tex]2\times 10^{-9}[/tex]) is the correct alternative.

Explanation:

Given:

Common ancestor,

= 50 million years ago

Base differences,

= 92

Now,

The predicted mutation rate will be:

= [tex]\frac{92}{50\times 10^6\times 1000}[/tex]

= [tex]\frac{1.84}{10^9}[/tex]

= [tex]1.84\times 10^{-9}[/tex]

or,

= [tex]2\times 10^{-9}[/tex]

Thus the above solution is the right one.
