Explanation:
Erosion is when the soil that is on the top of the land gets washed away by moving water. Fertile soil can help in preventing erosion because there will be more plants on fertile soil. When something like grass or any plant grows, the roots will hold the soil together more firmly. Vegetation is an effective measure against land degradation.
Answer:
Soil is a renewable resource that can be used in a sustainable manner. Fertility of soil can be sustained by protecting topsoil from erosion and contamination. Because soil fertility is replenished by decomposition of organisms, it is necessary to ensure that the natural life cycle of plants and wild animals is not disrupted. That is why reforestation is an effective measure against land degradation.

Why Are People Different Colors? Nina Jablonski, a biological rainbow of human skin color." She knew that our closest primate relatives have pale skin under dark fur, but human skin comes in a variety of shades from pinkish white to dark brown. How did this variation arise Many biological traits have been shaped by natural selection, Could human skin color be one such trait? If so, she would have to find the selective pressure that caused different populations to evolve varying levels of skin pigmentation. at Penn State University, spent many hours chinking about 'the sepia You will now meet Nina in a short five-minute video (https://www.hhmi.org/biointeractive/biology-skin-color). She will take you on a journey that she undertook in the pursuit of this question. After you have viewed the video, answer the following five questions. Questions 1. Describe the conditions necessary for evolution by natural sclection to take place in a population. 2. With regard to the evolution of skin color in humans, which of these conditions is Nina sure about (and why) and which one(s) is she investigating? 3. What is Nina's likely hypothesis about the evolution of skin color in humans? 4. How might she test her hypothesis?

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.

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.

Put the following in order from when they occur in the visual transduction pathway:
Optic Nerve receives signal:
Optic radiation receives signal:
Light hits photoreceptors (rods and cones):
Optic chiasm receives signal:
Ganglion cells receive signal:
Optic tract receives signal:
Bipolar cells receive signal:
Primary visual cortex receives signal:
Lateral geniculate nucleus of thalamus receives signal:
The visual pathway consists of the retina, optic nerves, optic Chaism, optic tracts, lateral geniculate bodies, optic radiations, and visual cortex.
The pathway is, effectively, part of the central nervous system because the retinae have their embryological origins in extensions of the diencephalon.
What is the pathway of vision steps?The visual pathway directs to the anatomical structures responsible for the transformation of light energy into electrical action prospects that can be analysed by the brain.
It begins at the retina and terminates at the primary visual cortex.

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.

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.
