5. Why do you think the concrete needs to be reinforced with steel bars?
Answer:
ABA namalayan ko Yan
Explanation:
dI ko Yan alam
sorry
In concrete construction, reinforcing steel rods, bars, etc absorbs tensile, shear, and occasionally compressive stresses. Because plain concrete cannot readily endure the strain and bending stresses induced by wind, earthquakes, vibrations, and other pressures, it is unsuitable for most structural purposes. It is also responsible for holding the concrete together in the right position.

Geographic isolation caused a population to separate and experience two different environments. With natural selection occurring over many generations, the two populations are no longer able to successfully mate and reproduce. This is what
happens is_____.
O evolution at the species level
O sympatric speciation
O microevolution leading to speciation
O allopatric speciation
Formation of new species or speciation as a result of geographic isolation is an example of allopatric speciation.
What is speciation?Speciation is the process by which new species are formed.
There are several types of speciation;
allopathic speciation sympatric speciation peripratic speciationparapatric speciationAllopatric speciation occurs when species which are isolated from one another by physical barrier, such as a mountain range or a waterway causes new species to form as a result of inability to interbreed.
Therefore, geographic isolation which leads to speciation is an example of allopatric speciation.

HUMAN EGGS AND SPERM EACH CONTAIN 23 _____, WHICH ARE COMPOSED OF LONG STRANDS OF _________.
Explanation:
HUMAN EGGS AND SPERM EACH CONTAIN 23 "Chromosomes"WHICH ARE COMPOSED OF LONG STRANDS OF "DNA"
Human eggs and sperm each contain 23 chromosomes, which are composed of long strands of DNA.
What are Chromosomes?Chromosomes may be defined as the thin, thread-like structure that appears during cell division. Chromosomes are generally found in the nucleus of the cell in the form of thread. These thread-like structures are made up of DNA, RNA, histones, and non-histone proteins.
The Chromosome was first discovered by E. Strasburger in 1875. But the term chromosome was given by Waldeyer in 1888.
Almost all the cells of the human body have 46 chromosomes. But there are two types of cells that are structurally and functionally different. These are known as the egg cells which are present in females and the sperm cells which are present in males.
Both these cell types in humans only have 23 chromosomes instead of 46. These chromosomes are remarkably composed of long and double strands of DNA.
Therefore, human eggs and sperm each contain 23 chromosomes, which are composed of long strands of DNA.

What are the effect of silt on aquatic organisms?Silt refers to small fine particles of sand or mud that forms a suspension in water.
Silt in oceans usually come from rivers opening into the sea
The silt suspended in the water surrounding a coral reef near the coast of a small island community in the Caribbean Sea will originate from rivers and streams opening into the sea.
The silt will reduce the population of algae on the coral reef as they increase water turbidity.
This will reduce fish population in the area and the food source for humans.
Industrial wastes are a source of mercury in lakes.
The presence of mercury will poison the lake and kill the fishes in the lake.
It will also make the water unfit for drinking by humans.
Therefore, pollution of water bodies kills aquatic organisms and this disrupts food source for humans.

Would you expect to find older or newer fossils in rock layers closer to the surface? Why?
Answer:
Newer
Explanation:
Because it is like when you place a plant and its roots underground and cover it up. You have the newer dirt going over the newest roots and the roots are close to the top
(If you aren't satisfied with that explanation here's another one) :
A hundred years ago dinosaurs existed and then they died and their remains were buried under dirt. However, we know that the fossils aren't anywhere near the top. Over time fossils get buried under layers of dirt the newer ones will be near the top because they haven't had time to be more buried.

The Endangered Species Act was passed in 1973, but many people today feel that the Endangered Species Act has not done enough to protect endangered species from human impacts. do you think that it needs to be updated? Give specific examples why or why not.
Answer:
Absolutely
Explanation:
only 3 percent of species protected by the law have recovered to the point where they are no longer threatened or endangered. The ESA can and should be strengthened so that it not only continues to protect species, but also promotes their full recovery.
In the last 100 years we human beings have eliminated 10 times more species than have disappeared in the past at the natural background rate. Without conservation, we are at risk of losing precious wildlife and depriving future generations of America’s heritage.
With the growing menace of climate change, many more species need our protection. In 1973, there were only 78 species listed in the ESA; now there are almost 1,600.
