Answer:
A. Cell theory.
Explanation:
The image above shows salamander skin cells as viewed under a microscope. The activity occurring inside the rectangle best supports a scientific theory known as cell theory with respect to cell division.
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
Cell theory states that cell is the basic unit of life, all living organisms are made up of one or more cells and they typically arise from existing cells i.e pre-existing cells give rise to new ones through the process of cell division.
From the image of the salamander's skin cell, we can see that it comprises of many cells and are these look very much alike, meaning they are from pre-existing cells.

Which statement best describes a population that competes for reproductive purposes?
Animals push each other to access water.
Hyenas quarrel over a fresh animal kill.
Squirrels and chipmunks collect food for the winter months.
Members of the same species battle each other to protect their young.
Answer:
DDDDD Members of the same species battle each other to protect their young.
Explanation:
The statement that best describes a population that competes for reproductive purposes is members of the same species battle each other to protect their young. The correct option is D.
What is competition?Competition is an interplay between life forms or species in which both necessitate a scarce resource.
Competition reduces the fitness of both organisms involved because the presence of one reduces the amount of resource available to the other.
The varying relationships between breeding success and specific traits in the two genders provide a foundation for predicting the shape of gender differences that are likely to evolve.
Adequate nutrition during pre-mating periods was found to have the greatest impact on various reproductive processes in mammals.
Members of the same species battle each other to protect their young, which best describes a population that competes for reproductive purposes.
Thus, the correct option is D.

Are the seasons (summer or winter) the same in the Northern and Southern Hemispheres
at the same time? When it is summer in the Northern Hemisphere, what season is it in the
Southern Hemisphere?
Answer: No they don't occur at the same time
Summertime in the northern hemisphere happens when it is winter in the southern hemisphere, and vice versa.
The tilt of the earth causes the seasons. The northern hemisphere's summertime means that the northern part of the earth gets more sunlight compared to the southern half, so the southern half experiences winter.
With the tilt held at the same angle, the earth revolves to another point in space, so that the northern hemisphere receives less sunlight and the southern hemisphere gets more. So the seasons swap.
Answer: Winter
Explanation: The tilt of the Earth determines the seasons for the Northern and Southern Hemisphere. When the Northern Hemisphere tilts toward the Sun, it experiences summer. At the same time, the Southern Hemisphere tilts away from the Sun. It experiences winter.

Filled-in symbols in the pedigree that follows designate individuals suffering from deafness.a. (2 points) Study the pedigree and explain how deafness is being inherited.b. (2 points) What is the genotype of the individuals in generation V
Answer:
According to the pedigree, It is clear that the F1 generation is not affected but their offspring are affected in F2, which explains that the deafness presented with the pedigree is recessive. It should be an Autosomal recessive inheritance as it is found in both male and female offsprings.
As it is found that the parents are affected in 5th gen and 6th generation but their offspring are not affected which means there must be more than one genes controlled this disorder
B. In 5th generations mentioned above offspring is unaffected but parents are affected, to find the genotype of the individual let assume there are two genes responsible for it A and B, and mutation in any one of them can result in deafness.
So in IV generation Individuals 5 and 6 have genotypeAAbb and aaBB; both are deaf.
gametes:- Ab & aB.
So, the genotype of all offsprings will be AaBb means all are normal.
Deafness is an autosomal recessive disorder as the first generation is unaffected and the genotype of the fifth generation is AaBb.
What are pedigree and genotype?Pedigree is a chart representation of the phenotype of specific genes of the organism and its inheritance from the ancestral family. The pedigree can be used for the analysis of the heritable disease and illness in the family root.
The deafness illness in the pedigree is recessive as the first generation of the pedigree remains unaffected but the later generation is affected and is diseased.
From the chart, deafness can be said to be an autosomal recessive disorder as some generations are unaffected and in some the disease is present. More than one gene is controlling the disease as the fifth and sixth generations are affected but not their offspring.
The parent of the fifth generation are affected but their progenies are normal to know the genotype let's assume the genes A and B to be responsible for the disease and the mutation in any one of the alleles will result in deafness.
Hence, the genotype of the parents 5 and 6 in the fourth generation will be AAbb and aaBB as both of them diseased or deaf, the offsprings produced from their cross will be AaBb that is all the offspring of the fifth generation will be normal and unaffected.
Therefore, the genotype of the fifth generation in the pedigree is AaBb.

A. An added force of 20 N to the side of the hill B. Added forces of 30 N up the hill and 20 N down the hill
C. Added forces of 30 N up the hill and 30 N down the hill
D. An added force of 20 N down the hill
An added force of 20 N down the hill will increase the speed of the bicycle, stronger gravity is applied to things with higher masses, hence option D is correct.
What condition if a bicycle down a hill at a constant speed?A force that unites things. You stay on the ground thanks to the Earth's gravity, which also causes things to fall. Everyone and everything is affected by gravity.
Gravity is the force that pulls the cyclist down toward the ground. Riding the bike ahead on a completely level road encounters very little resistance from the effects of gravity.
Cyclist gains speed even when they are not pedaling because the potential energy produced by a hill's height is converted into an equivalent increase in kinetic energy.
