Answer:

In medicine, genetic engineering has been used to mass-produce insulin, human growth hormones, follistim (for treating infertility), human albumin, monoclonal antibodies, antihemophilic factors, vaccines, and many other drugs. In research, organisms are genetically engineered to discover the functions of certain genes.

Through genetic engineering, animals can produce pharmaceutical proteins and replacement tissues in their milk, eggs, and blood, which can be used in the treatment of human diseases such as cancer, heart attacks, hemophilia, rheumatoid arthritis, pandemic flu, malaria and small pox.

Andrej [43]

Answer:

a. biomes

Explanation:

Ecology can be defined as the scientific study of the relationship between living organisms such as plants and animals in relation to their physical and biological environment.

An ecosystem can be defined as the natural living habitats of both living and non-living organisms, in which they interact with one another. Essential services such as plant pollination, water purification, nutrient cycling etc that are being provided by the ecosystem are really very vital, important and useful for the sustenance of life, both for humans and enhances social welfare.

Generally, the different continents on Earth are in a constant motion due to the fact that they're sitted on top of gigantic plates floating on Earth’s mantle.

Furthermore, the Earth’s core generate energy which also creates convection currents in the molten layer of the Earth, thereby, moving the plates.

Over an extremely long periods of time, the movement of these plates create new biomes.

In Ecology, a biome can be defined as a relatively distinct terrestrial region which is made up of animals, micrograms and plants, and it is typically characterized by similar environmental factors such as wind, relative humidity, rainfall, temperature, etc., irrespective (regardless) of where it occurs in the world.

There are five (5) main types of biomes and these are;

I. Forest.

II. Aquatic.

III. Desert.

IV. Grassland.

V. Tundra.

1. Compare the average global temperatures from the early 1900’s and the early 2000’s. How has the
sveticcg [70]

1. The average global temperatures from the 2000’s early are higher than those from the early 1900’s. We can see from the diagram that the average global temperature in the 1900s was about 57 degrees Fahrenheit (13.8 o C). In the 2000s the temperature raised to more than 58 F (about 14.5 o C). The world temperature is increasing due to human activity or natural variability. Some of the causes of this global warming are:  burning of fossil fuels, agriculture , deforestation all leading to greenhouse effect.

2. Carbon dioxide (CO2) is naturally present in the atmosphere as part of the carbon cycle, but its amount is raised due to human activities. This gas is produced by the process of burning fossil fuels (coal, natural gas, and oil), solid waste, trees and wood products..CO2 is removed from the air by the absorption of the plants or it dissolves into the ocean over a period of 20–200 years.

Methane is produced during the production and transport of coal, natural gas, and oil. It is removed from the atmosphere by chemical reaction, persisting for about 12 years.

Nitrous Oxide (N2O) is formed during agricultural and industrial activities or during the burning of fossil fuels and solid waste.N2O is destroyed in the stratosphere persisting for around 114 years.

Fluorinated gases such as hydrofluorocarbons, perfluorocarbons, sulfur hexafluoride, and nitrogen trifluoride are formed in different industrial processes. Those gases have long atmospheric lifetimes sometimes thousands of years.

3. Greenhouse gases such as CO2, N2O, fluorinated gases, methane are gases that trap the heat in the atmosphere, causing the warmer climate. The amount of a particular greenhouse gas in the atmosphere can be measured. Higher emissions of those gases lead to higher concentrations in the atmosphere. Because of the Industrial Revolution , atmospheric greenhouse gas amount is raised for the last century and that increased the global average temperature.

4. There are many ways for reducing the amount of CO2. Some of them are:

• Reduce Vehicle Emissions, since the use of vehicle for transport is one of the largest sources of this greenhouse gas. Drive a bike, get a gas-efficient vehicle or a hybrid car.

• Reduce Home Energy Carbon Emissions by insulating and sealing your home, turning off lights, add solar panels to the roof of your home etc.

5. Solar energy that travels to the Earth is absorbed by the its surface and converted into heat, which is released into the atmosphere. The greenhouse gases such as carbon dioxide (CO2) absorb that heat and send it back to the Earth's surface. This process is known as the greenhouse effect and it leads to temperature increase. This happens because the increase in greenhouse gases in the atmosphere trap too much heat.  

6. Since the greenhouse gases trap the heat, if there were less of those gases, much of the infrared radiation (solar  energy) that is converted to heat today would not be trapped in the Earth's atmosphere. The  temperature of the Earth would cool down, and a conditions of the Ice Age would occur. These conditions would be very unfavorable for plants and animals, oceans would freeze, and weather patterns would change.

Why can chromosomes be described as units of linked genes
Mrac [35]

Answer:

Genes that are located on the same chromosome and that tend to be inherited together are called linked genes because the DNA sequence containing the genes is passed along as a unit during meiosis unless they are separated by crossing over.
