A projectile is fired vertically upward at an initial velocity of 100 m/s. How high will it rise? How long will it take to reach that height?

Answers

Answer 1

The question is solved using the equations of motion

According to the equations of motion:

[tex]v^2 = u^2 -2gh[/tex]

v = final velocity

u = initial velocity

g = acceleration due to gravity

h = height

Note that at the maximum height, the final velocity (v) = 0 m/s

so we can write:

[tex]u^2 = 2gh[/tex]

[tex]h = \frac{u^2}{2gh}[/tex][tex]h= \frac{100^2}{2 * 10}[/tex]

h = 500 m

The time taken is obtained from:

[tex]v= u - gt[/tex]

since v= 0 at maximum height

[tex]u = gt\\\\t= u/g\\\\t= 100/10\\t = 10 s[/tex]

Imagine you discover a new human parasite like T. gondii that forms cysts in the brain. You suspect it is altering human behavior. You also determine that it is transmitted through sharing food. In what ways would you predict that it zombifies its hosts (alters their behavior)?

Answers

Hello. This question is incomplete. The full question is:

Imagine you discover a new human parasite like T. gondii that forms cysts in the brain. You suspect it is altering human behavior. You also determine that it is transmitted through sharing food. In what ways would you predict that it zombifies its hosts (alters their behavior)?

a. It should make them feel sick and rest in bed.

b. It should make them want to host more people for social dinners.

c. It should make them want to prepare meals more.

d. It should reduce their sanitary practices (e.g. washing hands) while preparing food.

e. It should make them want to horde food.

Answer:

a. It should make them feel sick and rest in bed.

b. It should make them want to host more people for social dinners.

c. It should make them want to prepare meals more.

d. It should reduce their sanitary practices (e.g. washing hands) while preparing food.

Explanation:

The options shown above are the only ones that show possible changes in personal behaviors related exclusively to the behavior of a person, who may be suffering from the damage caused by a parasite in the brain. The "e" option does not represent a change in behavior and does not depend exclusively on a sick individual due to the action of a parasite.

As you may already know, the brain governs our body in all factors, for this reason, cysts in this organ can trigger behavioral changes.

Answer: a. It should make them feel sick and rest in bed.

Toxoplasma gondii is a protozoan parasite that causes toxoplasmosis, a generally mild but potentially fatal disease, especially in cats and human fetuses. Cats and other felines are considered their ultimate hosts because the sexed phase of their life cycle takes place there, making these animals the primary hosts of the parasite. The asexual phase of the life cycle can occur in any warm-blooded animal, such as other mammals and birds. Therefore, toxoplasmosis is a parasitic zoonosis.

Parasites invade the cells, forming a compartment called the parasitophore vacuole which form cysts in tissues, especially in the muscles and brain. Because the parasite is inside the cells, the host immune system does not detect these cysts. Antibiotic resistance varies, but cysts are difficult to eradicate entirely. Therefore, T. gondii spreads within these vacuoles through a series of binary divisions until the infested cell eventually breaks free.

Some people have flu-like signs and symptoms, which may be:

Swollen lymph nodesHeadacheFeverFatigueWidespread pain

In people with impaired immune systems, symptoms may also include:

ConfusionLack of coordinationConvulsionsBlurred vision caused by intense swelling of the retina

In recent years, several investigations indicate that the parasite can cause changes in the behavior associated with impulsivity, and personality disorders. So, we could predict it zombifies the host by changes in the behavior, because of the damage caused by a parasite in the brain. It is important to consider that the brain governs the body, and cysts found there can trigger these changes.

In ______ immunity the individual produces antibodies against particular pathogens while in ______ immunity the individual is given specific antibodies against a pathogen. Group of answer choices

Answers

Answer:

The correct answer is - active and passive.

Explanation:

Immunity is the capability of multicellular organism to protect itself from harmful molecules that are foreign to the body such as microorganism and antigens. Immunity can be active immunity or the passive immunity.

Active immunity takes place when one's own body produces antibodies to fight against a particular disease or antigen by immune system where as passive immunity occurs when an individual receives antibodies from outside and produced outside.

Thus, the correct answer is - active and passive.

Abnormal vascular regulation by endothelial cells in small vessels of the heart contributes to:___________. a. Hypertension b. Dysrhythmias c. Truncus arteriosus d. Ischemic heart disease

Answers

Answer: The correct answer to the question is option D

ISCHEMIC HEART DISEASE.

Explanation: To answer the question effectively, let us look at the options given,what they are and how they affect the heart.

Endothelial cells play a crucial role in the regulating vascular tone,They do so by secreting variable amounts of constricting and relaxing factors inorder to control tissue perfusion.

Hypertension on the other hand occurs as a result of factors that varies distinctively and not all related to vascular tone.

Dysrhythmias on it's own will affect the function and conduction of heart chambers but not necessarily vascular tones.

Truncus arteriosus results in only in one large artery exiting/leaving the heart.

Rima eat guava explain how the teeth tongue and sliva will help to break it down​

Answers

Answer:

Please find the role of teeth, tongue and saliva in digesting guava below

Explanation:

Digestion is generally the process of breaking down complex food substances into their simplest form. However, as easy as this sounds, there are series of processes that must take place in between to achieve the final result.

Once a food substance like guava enters the mouth (ingestion), it initially gets chewed by the TEETH in order to break it down to smaller masses that can be swallowed. During the process of chewing, the TONGUE helps to move the food around the mouth and later helps push it down the gullet/digestive tract. SALIVA, on the other hand, creates a moisturizing environment for the food to form a Bolus (round mass of food ready to pass down the esophagus). The saliva also contains an enzyme called AMYLASE that helps chemically degrade starch content of the food before passed through the digestive tract.

When you examine fluid that you have drawn from a blood vessel in someone's arm, you find that it is relatively high in carbon dioxide and waste products. Assuming that the fluid comes from a healthy individual, you conclude that the blood vessel from which you have drawn blood could have been ______.

Answers

Answer:

The given blank can be filled with a venule.

Explanation:

A small blood vessel in the microcirculation, which connects the capillary beds to the veins is known as the venules. Various venules combine to form a vein. The walls of a venule are formed of three layers, that is, the inner endothelium formed of squamous endothelial cells, a middle layer of elastic and muscle tissue, and an external layer formed of fibrous connective tissue.  

The size of a venule ranges from 8 to 100 micrometers in diameter and are produced when capillaries come in close association. A venule refers to a small blood vessel that permits the deoxygenated blood high in carbon dioxide and waste products to return from capillary beds to the bigger blood vessels known as veins.

   GMO foods are easier and less costly for farmers to grow, which makes them cheaper for the consumer. ...

   The main concerns around GMOs involve allergies, cancer, and environmental issues — all of which may affect the consumer.

The advantages include improved human health, increased food production, reduced environmental impact, and so on. There is a risk that new diseases originating in genetically engineered animals will be transmitted to non-genetically engineered animals, including humans.

What is genetic engineering?

Genetic engineering (also known as genetic modification) is a process that uses laboratory-based technologies to alter an organism's DNA makeup.

This could be as simple as changing a single base pair (A-T or C-G), deleting a region of DNA, or adding a new segment of DNA.

Gene therapy aims to modify genes in order to correct genetic flaws and thus prevent or cure genetic diseases. The goal of genetic engineering is to modify the genes in order to improve the organism's capabilities beyond what is normal.

The benefits include improved human health, increased food production, and reduced environmental impact, among other things. There's a chance that new diseases originating in genetically engineered animals will spread to non-genetically engineered animals, including humans.

Thus, these are some pros and cons of the genetically modified animals.

Answers

Answer:

Maximum temperature was 40 Celsius at daytime while temperature at night was 31 Celsius.

Explanation:

Yesterday maximum temperature was 40 Celsius at daytime while temperature at night was 31 Celsius because during daytime the intensity of sunlight increases the temperature of the particles present in the atmosphere.  So at daytime, temperature increases while at night decrease occurs in the temperature. There is a lot of fluctuation in temperature at daytime due to increasing and lowering the intensity of light.

Answer:

The difference between the high and low temperatures in New York City was 12 degrees. One reason for the temperature difference is Earth’s rotation. Temperatures are generally warmer during the day because that side of the planet is heated by the Sun. At night, that side faces away from the Sun. So, temperatures will be cooler.
