Barley yellow dwarf disease is a viral disease that affects cereal crops, including barley, wheat, oats, and rye. The primary inoculum in barley yellow dwarf disease cycle is the aphids that transmit the virus from plant to plant. These aphids are known as the vectors of the disease, as they feed on the plant sap, which contains the virus particles.

When the aphids feed on the infected plant, they pick up the virus particles and carry them to the next plant they feed on, thus spreading the disease.
The initial infection of the plant by the virus is known as the primary inoculum. In the case of barley yellow dwarf disease, the primary inoculum is the virus particles that are introduced to the plant by the aphids. The virus particles infect the plant cells, and the disease symptoms become apparent. These symptoms include stunted growth, yellowing of the leaves, and reduced yields.
To control the spread of barley yellow dwarf disease, it is important to manage the aphids that transmit the virus. This can be done by using insecticides or by using resistant plant varieties. By reducing the population of aphids, the primary inoculum in the disease cycle can be reduced, which will help to control the spread of the disease.

They have long sharp claws which help them rake the soil to find food and roots. Almost eighty percent of their diet consist of plant material while the rest is animal protein.

Explanation:

The Biological Species Concept (BSC) states that a species is a group of organisms that can interbreed and produce fertile offspring. Wolves and coyotes can produce fertile offspring, but they are not the same species under the BSC.

This is because they have varied behaviours, habitats, and foods as a result of their long history of independent evolution.

Coyotes are smaller, live alone or in couples, and kill smaller animals while wolves are larger and more gregarious, living in packs and hunting huge prey.

Furthermore, wolves and coyotes rarely breed in the wild, and even when they do, the offspring are infertile and incapable of procreation.

This shows that wolves and coyotes are still considered genetically separate species by the BSC despite having the ability to create viable pups.

An acute infection of the throat that can lead to swelling and closure of the glottis and cause suffocation is known as epiglottitis.

Epiglottitis is a serious condition that occurs when the epiglottis, a flap of tissue at the base of the tongue that prevents food from entering the windpipe during swallowing, becomes inflamed and swelling occurs in this region. This can lead to a narrowing or closure of the airway, making it difficult to breathe.

Epiglottitis is usually caused by a bacterial infection, most commonly Haemophilus influenzae type b (Hib) in children, but can also be caused by other bacteria or viruses.

Symptoms of epiglottitis include high fever, severe sore throat, difficulty swallowing, drooling, and a muffled or hoarse voice. If left untreated, epiglottitis can lead to respiratory failure and death. Treatment typically involves hospitalization, airway support, antibiotics, and anti-inflammatory medications. Vaccination against Hib is recommended as a preventative measure against epiglottitis in children.

The answer is "Second trimester--bones start to replace cartilage; fetus begins to produce urine"

Explanation:

Around week 13 is when the 2nd trimester starts, which is also when urine is produced and bones replace cartilage! I took human biology and learned this too! :)

The statement second trimester—bone starts to replace cartilage; fetus begins to produce urine is correctly matched with their corresponding events during fetal development.

For both the mother and the unborn child, the second trimester is a turning point. Most of the time, you'll start to feel better and start to show more of the pregnancy.

Your pregnancy is in its second trimester from week 13 to week 28, or roughly months four, five, and six. During these weeks, in addition to appearing and feeling more pregnant, you may also have more energy than in the first trimester.

Because it can result in a preterm birth, PPROM in the second trimester is a major concern. Infants born between the 24th and 28th weeks of pregnancy are most likely to experience serious health issues in the future.

Explanation:

The trade winds are the kind of wind that blows towards the equator from the southeast in the southern hemisphere or the northeast in the northern hemisphere, especially at sea.

The horse latitudes are present in both the northern hemisphere and southern hemisphere with calm air and occur between trade winds and the westerlies that move towards the equator.

Answer:

ANS 1) Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. Currents are cohesive streams of seawater that circulate through the ocean.

ANS 2)n the deep ocean, the predominant driving force is differences in density, caused by salinity and temperature variations (increasing salinity and lowering the temperature of a fluid both increase its density). There is often confusion over the components of the circulation that are wind and density driven.

The global circulation patterns, specifically the North Pacific High in summer and the westerlies in winter, greatly influence the climate of Southern California.

In Southern California, the global circulation patterns have a significant influence on the climate, with variations between the summer and winter seasons. Here's how it affects the weather:

1. Summer Circulation:

During the summer, the region is influenced by the North Pacific High-pressure system, also known as the Pacific High. This semi-permanent subtropical high-pressure system develops over the northeastern Pacific Ocean, off the California coast. The Pacific High brings about stable, warm, and dry conditions to Southern California during the summer months. The clockwise circulation around the high-pressure system leads to the development of offshore winds, commonly known as Santa Ana winds, which can further amplify dry and warm conditions.

2. Summer Weather:

Due to the influence of the Pacific High, Southern California experiences hot and dry summers. The high-pressure system blocks the intrusion of marine air from the nearby ocean, resulting in limited cloud cover and minimal rainfall. The dry conditions, combined with the offshore winds, contribute to increased fire risk and elevated temperatures in inland areas.

3. Winter Circulation:

In winter, Southern California is influenced by the westerlies, which are prevailing winds that blow from west to east. The westerlies are part of the mid-latitude circulation patterns and are responsible for the movement of weather systems across the region. The jet stream, a high-speed river of air in the upper atmosphere, plays a significant role in steering storm systems during the winter months.

4. Winter Weather:

The westerlies and the associated jet stream play a crucial role in bringing precipitation to Southern California during the winter season. Storm systems from the Pacific Ocean travel eastward along the jet stream, reaching the region and bringing rainfall. The intensity and frequency of storms can vary from year to year, impacting the amount of precipitation received. These winter storms are crucial for replenishing water resources and contributing to the overall seasonal rainfall in the area.

Overall, the global circulation patterns, specifically the North Pacific High in summer and the westerlies in winter, greatly influence the climate of Southern California. Understanding these circulation patterns and their seasonal variations helps in predicting and understanding the region's weather patterns, including temperature, precipitation, and wind conditions.
