Which is the highest population density of grasshoppers?
O
A. 35 grasshoppers/10 square meters
o
O
B. 40 grasshoppers/20 square meters
O C. 1 grasshopper/1 square meter
O D. 50 grasshoppers/30 square meters
35 grasshoppers/10 square meters has the highest population density.
The highest population density of grasshoppers is 35 grasshoppers/10 square meters because more number of organisms are present in less area as compared to other population density. In the option i.e. 40 grasshoppers/20 square meters and 50 grasshoppers/30 square meters have more number of organisms but the area is also greater.And we know that high population density means more number of organisms in less area so we can conclude that 35 grasshoppers/10 square meters has the highest population density.

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.

what is the process that breaks down nucleic acids into nucleotides
a. dehydration synthesis
b. synthesis
c. polymerization
d. hydrolysis
please help ty
Answer:
D. Hydrolysis
Explanation:
Dehydration synthesis reactions build molecules up and generally require energy, while hydrolysis reactions break molecules down and generally release energy. Carbohydrates, proteins, and nucleic acids are built up and broken down via these types of reactions, although the monomers involved are different in each case.
I hope this helps have a great day :)
The process that breaks down nucleic acids into nucleotides is hydrolysis. The correct option is d.
What is hydrolysis?Any chemical reaction in which a water molecule breaks one or more chemical bonds is known as hydrolysis.
When water is the nucleophile, the phrase is used generically to refer to substitution, elimination, and solvation processes.
Nucleo depolymerase is another name for nuclease. By cleaving the phosphodiester bond that connects the nucleotides in the nucleic acids, the nucleic acid is broken down into nucleotides.
Either an enzyme or a non-enzyme can cleave the nucleic acid chain. Since the initial step in the alkaline hydrolysis of a polynucleotide is the transfer of the bond from C5' of the subsequent nucleotide to C2' of the same nucleotide, a 2'-OH group is necessary.
Thus, the correct option is d.

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.
Thus, the correct answer is Option C.

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.
