What is the shape of an Acid-fast bacteria?

Answer:

Chemical and mechanical digestion are the two methods your body uses to break down foods. Mechanical digestion involves physical movement to make foods smaller. Chemical digestion uses enzymes to break down food.

Explanation:

Answer:

Chemical digestion is being able to absorb nutrients from the food you eat. Mechanical digestion is physical movements like chewing to break down the food.

Answer:

This is the digestive system.

Explanation:

We can tell that this is the digestive system because we can see #1: The stomach, #2: The small intestine, #3: The large intestine, and #4: The liver. Hope this helped!

The diagram explains food digestion and absorption, thus this diagram of the human digestive system. The organs that are included are the stomach (1), small intestine (2), large intestine (3), liver (4).

The digestive system of humans consists of several organs such as the stomach, the small intestine, the pancreas, etc. The digestion of carbohydrate and lipid started partially in the buccal cavity with the help of amylase and lipase.

Actual digestion starts when the food enters the stomach. The stomach has an acidic environment, and pepsin is an enzyme that breaks down proteins. Then this partially digested food enters the small intestine. There, the food is mixed with pancreatic juice and bile. All the enzymes present here can break down the food properly and then the food gets absorbed into the blood. The large intestine excretes undigested food to the outside as feces.

Hence, the diagram explains the digestive system of a human.

Vegetation on Earth would be expected A. At the equator form the average amount of water vapor in a column of atmosphere.

The map shows that the average amount of water vapor in a column of atmosphere is highest at the equator. This is because the equator receives the most direct sunlight, which heats the air and causes it to rise. As the air rises, it cools and condenses, forming clouds and rain. This provides the water that plants need to grow.

At higher altitudes, the air is colder and drier, which is not ideal for plant growth. At lower longitudes, the sun's rays are less direct, which also reduces the amount of water vapor in the air. At the poles, the climate is too cold and dry for most plants to survive.

Therefore, based on the data in the map, would expect vegetation on Earth to be most dense at the equator.

A dominant gene is a type of gene which dominates in the inheritance pattern and masks the other one, on the other hand, a recessive gene is that which does not show its trait in inheritance pattern and hidden by the dominant one. A dominant gene is stronger gene while the recessive gene is a week gene. Dominant gene is always expressed in the upper case letters like A, F, V whereas recessive gene is always denoted by the lower case letters like a, f and v. dominant gene show in the inheritance when one of the two genes is dominant but in case of recessive gene both the genes of a trait should be recessive.

Traits you get from your parents. Inherited features evolve due to genetic material rearrangement and mutation. The parents transfer those traits (inherited) to their offspring. These aren't dying but passed on to the next generation. Example: earlobe attached or free, and curly hair.

An acquired characteristic is a non-heritable change in a function or structure of a living organism caused after birth by disease, injury, accident, deliberate modification, variation, repeated use, disuse, misuse, or other environmental influence. Acquired traits are synonymous with acquired characteristics. They are not passed on to offspring through reproduction.

Answer:

Neutrons have no charge and are the lightest subatomic particle

Explanation:

Nucleus of an atom contains three subatomic particles. These are protons, neutrons and electrons.

Mass of a proton is  \(1.67\)×\(10^{-27}\)kg.

Mass of a neutron is  \(1.67\)×\(10^{-27}\)kg.

Mass of an electron is \(9.1\)×\(10^{-31}\) kg.

Also, protons are positively charged, neutrons have no charge and electrons are negatively charged.

Therefore, we can conclude that the mass of a neutron nearly equals the mass of a proton.

Meiosis is the process by which the reproductive cells are created. Those reproductive cells are called "gamete cells", in opposition to the other cells that are called "autosome cells". As it's goal is to promote reproduction, the gamete cells always have half of the number of chromosomes that would be found in autosome cells. This is important because two gamete cells must merge in order to ensure that reproduction takes place, and two gamete cells must become one autosome cell. So, gamete cells have an haploid number of chromosomes (n) and the autosome cells have a diploid number of chromosomes (2n, meaning the double of the amount of chromosomes in n).

Therefore, the correct answer is:

b) gamete cells and d) haploid number of chromosomes

Birds migrating by day use the Sun to navigate, adjusting their angle to the Sun as the Sun's position moves from east to west.

Birds are warm-blooded vertebrates that belong to the class Aves (/eviz/). They are distinguishable from other vertebrates by having feathers, toothless beaks, hard-shelled eggs, high metabolic rates, four chambered hearts, and sturdy yet lightweight bones. The largest bird is the 2.8 m (9 ft 2 in) ostrich, while the smallest is the 5.5 cm (2.2 in) bee hummingbird. The majority of the ten thousand or so species that are still alive are passerine, or "perching," birds. Despite the fact that the development of wings differs between species, only the extinct moa and elephant bird species are known to be wingless. Birds' wings, which are essentially modified forelimbs, are what allow them to fly.

Answer: Negative Effect of Raising Livestock on Water Resources:

Raising livestock contributes to water pollution. According to the United States Environmental Protection Agency (EPA), animal waste is a significant source of water pollution. When animal waste is not adequately managed, it can contaminate nearby water sources, leaving harmful bacteria and nutrients that can impact aquatic life and human health. The EPA estimates that animal feeding operations produce over 500 million tons of manure per year, which is three times the amount of human waste in the United States.

Moreover, raising livestock involves the use of water resources. The amount of water that livestock requires varies depending on many factors such as animal type, weather conditions, and feed production. According to the Food and Agriculture Organization (FAO), raising a cow requires 9900 gallons of water, while raising pigs and chickens requires 700 and 4300 gallons of water, respectively. This creates a significant strain on water resources, especially in areas that already face a water scarcity issue.

Furthermore, raising livestock also contributes to the degradation of riparian habitats. Riparian habitats are those that exist along the banks of rivers and streams. These habitats play an essential role in stabilizing the banks of rivers, filtering pollutants, and providing a natural habitat for aquatic life. However, raising livestock near these areas can result in the trampling of habitats, the destruction of vegetation, and the accumulation of manure. This can lead to erosion, loss of biodiversity, and reduced water quality.

Conclusion:

In conclusion, raising livestock has a negative effect on water resources. By polluting water sources, using significant amounts of water resources, and contributing to the degradation of riparian habitats, the environmental impact of raising livestock poses a significant threat to aquatic life and human health. Unless farming practices are regulated, and best practices are implemented, raising livestock will continue to pose a severe risk to water resources.
