All of the following are physical characteristics used to determine race except
a. skin color
C hair texture.
b. eye color
d. body structure.
The physical attributes that are used to determine race may not include body structure.
Body structures are generally influenced by the environment that a person lives or what they do irrespective of whether it is genetic or otherwise.
Skin color, hair texture, and eye color, however, are determined by genes located on human chromosomes. Thus, these attributes give an indication of the race that a person belongs.

El Niño is caused by __________. A) ocean currents B) the isolation of continents C) orography D) all of the above
Answer:
A) ocean currents is correct
Explanation:
El Niño is caused by ocean currents. So, the correct option is (A).
What are Ocean currents?An ocean current is a type of continuous, directed movement of ocean water that is generated by a number of forces acting on the water including wind, the Coriolis effect, breaking waves, cabling, and temperature and salinity differences.
These can be caused by density differences in air, water masses that occur due to temperature and salinity variations, gravity, and events such as earthquakes or storms. These are continuous streams of sea water that spread through the ocean.
An El Niño condition typically occurs when surface waters in the equatorial Pacific become warmer than average and easterly winds become weaker than normal.
Thus, El Niño is caused by ocean currents. So, the correct option is (A).

Nitrogen containing fertilizer are used by farmers to promote crop and plant growth. These fertilizers can runoff into various nearby water bodies. In a process called eutrophication, nitrogen dissolves in a body of water and stimulates the growth of plants and algae. When these plants and algae die, bacterial populations feeding on the dead material increase and consume a lot of oxygen in the water. Which of the following is likely to occur as a result of using nitrogen containing fertilizer?
Answer:
This process will harm marine life due to scarcity and reduction of oxygen levels. This will significantly harm the marine ecosystem as well.
Due to a lack of oxygen and other factors, this procedure will destroy marine life. The marine ecology will also suffer considerably as a result of this.
What is the importance of nitrogen in the environment?Farmers employ fertilizers that contain nitrogen to encourage the growth of their crops and plants. These fertilizers may leak into a number of surrounding bodies of water.
Nitrogen dissolves in a body of water through a process known as eutrophication, which promotes the growth of plants and algae.
Fertilizers give plants the nutrients' potassium, phosphorus, and nitrogen, so they can grow larger, more quickly, and generate more food.
Therefore, nitrogen in particular is a vital ingredient for the growth of every living on Earth.

calculate the weight of an object whose mass is 30 kg and acceleration due to gravity 10 m/s2
Answer:
300 N
Explanation:
[tex] m = 30 \: kg \\ g = 10 \: m {s}^{ - 2} \\ w =? \\ \because \: w = mg \\ \therefore \: w = 30 \times 10 \\ \therefore \: w =300 \:N \:(Newton) [/tex]
The weight of the object having a mass of 30 Kg is 300 N
The weight and mass of an object are related according to the following equation:
W = mgWhere:W is the weight
m is the mass
g is the acceleration due to gravity.
With the above formula, we can obtain the weight of the object as follow:Mass (m) = 30 Kg
Acceleration due to gravity (g) = 10 m/s²
Weight (W) =?W = mg
W = 30 × 10

What is a chromosome?
A chromosome is a thread-like structure found in the nucleus of cells that carries genetic information in the form of genes. Chromosomes are made up of DNA, which is a chemical compound that contains the instructions for the development and functioning of all living organisms.
In most organisms, chromosomes are arranged in pairs, with one chromosome of each pair inherited from each parent. The complete set of chromosomes in an organism is known as its genome. The genome of an organism contains all of the genetic information necessary for the organism to develop, grow, and function.
Chromosomes come in different sizes and shapes, and the number of chromosomes can vary among different species. For example, humans have 23 pairs of chromosomes, for a total of 46 chromosomes, while dogs have 39 pairs of chromosomes, for a total of 78 chromosomes. The number and arrangement of chromosomes can play a role in the characteristics and traits of an organism.
