1. Which is a source of genetic variation?
a. Mutations
b. artificial selection
C. exponential growth
d. genetic bottlenecking
Answer:
Mutation is a source of genetic variation
Answer:
Mutations
Explanation:
Mutations, the changes in the sequences of genes in DNA, are one source of genetic variation. Another source is gene flow, or the movement of genes between different groups of organisms. Finally, genetic variation can be a result of sexual reproduction, which leads to the creation of new combinations of genes.
Why do you have to determine the total magnification when observing a specimen under the compound microscope?
Answer:
To clearly see specimens under the microscope, and to be able to see two separate objects that are close together.
Explanation:
A microscope is a tool that makes an object look bigger so that the person who is looking at it can see it. It's important to use a microscope because cells are usually too small to see with the naked eye. In addition to magnification, microscopes also have resolution, which is the ability to see two objects that are close together as separate. A microscope needs both magnification and resolution to be able to clearly see specimens under the microscope. When the light microscope bends light at the specimen, it gives the viewer a clear picture of the specimen. A series of lenses do this.

Location 1
Location 2
Location 3
Location 4
The cost of mining and reclamation for location 4 will cost the most at the end of the mining period.
Location 4 will cost the most for mining and reclamation at the end of the mining period because the cost of mining and reclamation of the location 4 is $7,000 per 65 daysWhile on the other hand, the cost of mining and reclamation of location 1 is $5,000 per 30 days, location 2 is $4,500 per 45 days and location 3 is $3,500 per 120 days.So from this information we can conclude that the cost of mining and reclamation for location 4 will cost the most at the end of the mining period.Learn more about mining here: https://brainly.com/question/5934586

brief summary of conservation of forests & wildlife
least 10 page
With the advent of industrialization, several trees have been cut at an alarming rate for raw materials and various other purposes. This felling of trees can be regulated by selective cutting, clear-cutting and shelterwood cutting.
Forest fires are one of the common causes of loss of forests. Sometimes the forest land is set on fire to make the land available for commercial purposes. Once cleared, there can be no vegetation. Natural forest fires are also responsible for the destruction of huge forest covers. Latest fire fighting techniques should be adopted to conserve the forest. However, forest fires are an important part of the ecosystem and it helps replenish nutrients in the soil from dead and decaying matter.
More trees should be planted to increase the forest cover. Trees should be selected according to the geographical conditions of a particular region and proper care should be taken during the growth of trees.
Prevention of exploitation of forestry and forest products is necessary for the conservation of forest.
The existing forests should be protected from diseases by spraying chemicals, antibiotics or development of pest-resistant strains of trees.

Which statement is true about the law of reflection?
The angle of reflected light is the same as the incoming angle of light.
The angle of reflected light distorts the image to appear larger or smaller.
The angle of reflected light is smaller than the incoming angle of light.
The angle of reflected light is larger than the incoming angle of light
Answer:
The law of reflection defines that upon reflection from a smooth surface, the angle of the reflected ray is equal to the angle of the incident ray, with respect to the normal to the surface that is to a line perpendicular to the surface at the point of contact.
The reflected ray is always in the plane defined by the incident ray and the normal to the surface at the point of contact of the incident ray.
The images produced by plane mirrors and curved mirrors can be understood by the law of reflection.
Law of reflection is defined as:
The principle when the light rays falls on the smooth surface, the angle of reflection is equal to the angle of incidence, also the incident ray, the reflected ray, and the normal to the surface all lie in the same plane.
What is Reflection of Light?
The process through which light rays fall on the surface and gets bounced back is known as a reflection of light.
Explanation:
Answer: The angle of reflected light is the same as the incoming angle of light.
Explanation:
The law of reflection states that the incident ray, the reflected ray, and the normal to the surface of the mirror all lie in the same plane. The angle of reflection is equal to the angle of incidence.

draw the flow chart showing the sequential order of reproductive stage and fertilization
The sequential order of reproductive stage and fertilization starts with the
male and female sex cells being produces through meiosis. The male sex
cell which is the sperm is produced in the testes while the female sex cell
which is the egg is produced in the ovary.
During copulation, the sperm cells are released into the vagina which then
swims through the cervix and uterus to the fallopian tubes where the
fertilization occurs.
There is then movement of the zygote formed from the fertilization to the
uterus where development occurs.

. What is the width of Grandmother’s pelvis, measuring from the pelvic brim? How does her pelvis differ
from Grandfather’s?
The width of Grandmother’s pelvis, measuring from the pelvic brim is 2cm.
The grandmother has a wider pelvis than the grandfather.
The pelvic brim is found at the edge of the pelvic inlet and measures around
2cm. The pelvis in females are always wider than those found in males. This
is due to the adaptation of the female pelvis to child birth.
The pelvis being wider aids the passage of the foetus from the womb and
eases childbirth. This is the reason why the grandmother has a wider pelvis
than the grandfather.

The only system that does not pass through the thalamus on its way to the cerebral cortex is the __________ system. A. Tactile B. Gustatory C. Olfactory D. Visual.
The cerebral cortex process the information delivered by the thalamus, the information is related to the senses.
The only system that does not pass through the thalamus on its way to the cerebral cortex is the olfactory system.
The systems that pass through the thalamus are:
1. The visual sensation or information passes through the visual occipital cortex. It then delivers the information from the thalamus to the cerebral cortex.
2. The gustatory cortex is the region of the cerebral cortex, which is responsible for the senses of tastes and flavor. It also passes through the thalamus on its way to the cerebral cortex.
3. The tactile system includes the senses of touch. It is the information received through the receptors present on the skin. It also delivers the information to the cerebral cortex via the thalamus.
4. The olfaction system is not involved in the thalamus pathway. The olfactory cortex is present in the temporal lobe, which is not routed through the thalamus.
