Answer:

There are only four parts of skill related fitness in the options; they are:

Speed

Agility

Balance

Coordination

Explanation:

Physical fitness refers to the ability to perform physical activities well without fatigue. In other words, being physically fit refers to a state of general wellbeing. Physical fitness can either be health-related or skill-related. The skill-related components are six in number viz: agility, power, balance, coordination, speed and reaction time.

However, only four of these skill-related parts of physical fitness are mentioned in the options of this question. They are:

- Speed: This refers to the ability to run a distance in a short time frame.

- Agility: This is the ability to move easily and quickly in different directions

- Balance: The ability to maintain an upright body position during training or physical activity

- Coordination: The ability to make physical senses of one's body (eye) cooperate with the limbs (hands and feets) during a physical activity.

What are two major advantages of high-yield modern agriculture? what are the major harmful environmental impacts of agriculture?
goldfiish [28.3K]
1.High yield modern agriculture refers to the practice of breeding genetically modified crops or using fertilizer to increase the production yield of planted crops. Two advantage of high yield modern agriculture are:
1. Production of large quantities of planted crops.
2. Ability to select and breed plants with superior qualities.

2. Agriculture have some negative influence on the environment, the major harmful environmental impacts of agriculture are:
a.  Habitat loss: Agricultural practices present great danger to species and ecosystem. This is because, farmed areas serve as habitats for different types of wild plants and animals. Farming the areas makes these living organisms to lose their habitats and these throw the ecosystem into imbalance.
b. Soil erosion and degradation: When natural vegetation are converted into agricultural lands, the breaking up of the soil leads to erosion, which wash away the top soil and the nutrients that are embedded in it. 
c. Pollution: The chemicals that are used during farming operations, such as fertilizers, pesticides, etc. cause pollution of the air and the surrounding waters.
3. Soil erosion is the process by which the top layers of soils are carried away by agents such as wind and water. The biggest negative effect of soil erosion is the loss of top soil. The top soil is the part of the soil that contain most of the nutrients that plants use to grow. When this part of the soil is lost, the soil usually becomes non fertile. Soil erosion can also lead to water pollution. When soils are eroded from the farm lands and carried to the surrounding waters, the waters will be polluted by the chemicals such as pesticides, herbicides and fertilizers, which are had been used on the soils. This can lead to the death of the animals that are living in the waters.

Through which microscope were cells first observed?
poizon [28]

Compound microscope

<h3>Further explanation</h3>

In 1665, Robert Hooke used a compound microscope to observe cells. Hooke observes the cell walls of dead plants (in the form of cork) when they appear under a microscope. He named it the cell because it looked similar to a cellula or small room inhabited by monks.

Development of microscopy:

  • 1590: Hans and Zacharias Janssen, as Dutch lens grinders, mounted two lenses in a tube to produce the first compound microscope.
  • 1660: Robert Hooke published <em>Micrographia</em>, containing detailed observations of biological materials made with the best compound microscope.
  • 1676: Anton van Leeuwenhoek was the first person to observe a live cell under a microscope, i.e., the algae Spirogyra.
  • 1931: Ernst Ruska constructed the first electron microscope. With the invention of the electron microscope, many infectious agents smaller than bacteria could be seen.

Until now, we can see how important the use of microscopes, especially in microbiology, that is the study of microorganisms.
