Which of the graphs below best illustrates homeostasis? Graph A Graph B Graph C Graph D
The graphs below best illustrate homeostasis in - graph D as internal temperature maintains equilibrium and shows very little fluctuation with change in external temperature.
Homeostasis is the state of regulating the internal environment including internal, physical, and chemical conditions in response to the change in the external environment by living systems.
This regulates various variables such as body temperature and fluid balance, being kept within a certain homeostatic range.Any self-regulating process involves maintaining stability while regulating to conditions that are best for its survival.In this graph, graph D shows very minimal change and maintains a normal body temperature range even there is fluctuation in external temperature.

In order for an statonary object to move, an unbalnced force must act upon it.
True
False
Answer:
true
Explanation:
any force can be added to make a stationary object move. but if it was balanced then it would just stay in position
if there is 100N of force going towards the object, and you are pushing the object with 100N force. It will not move.
Final answer:
The statement that an unbalanced force must act upon a stationary object to set it into motion is true according to Newton's first law of motion. An object at rest remains at rest, while an object in motion maintains its velocity unless acted upon by an unbalanced force.
Explanation:
The statement that an unbalanced force must act upon a stationary object to set it into motion is True. According to Newton's first law of motion, also known as the law of inertia, an object will not change its state of motion (i.e., it will not accelerate) unless an unbalanced force acts upon it. This means that if an object is at rest, it will stay at rest until a force that is greater than the sum of all opposing forces is applied to it. Contrary to misconceptions, a force can do work even if an object doesn't move, for instance if you're pushing against a wall with a force, work is being done on a molecular level, although there's no macroscopic movement.
When two unequal forces act on an object, the object will move in the direction of the net or resultant force, which is the vector sum of all the forces acting upon it. If this net force is zero, the object will remain stationary or continue to move at a constant velocity. This is a fundamental concept in classical mechanics.

The organisms in the diagram belong to the taxonomic group of Fungi. They are eukaryotic organisms that appeared on land over 450 million years ago and feed on decaying and dead matter.
Explanation:The organisms that fall in the given diagram likely belong to the taxonomic group of Fungi. Fungi are eukaryotic organisms that appeared on land over 450 million years ago. They differ from plants and animals in several ways. For example, they are heterotrophs and contain neither photosynthetic pigments such as chlorophylls nor organelles such as chloroplasts. Fungi feed on decaying and dead matter, making them saprobes. Fungi can be unicellular like yeasts or can develop a network of filaments called a mycelium. The cell of a fungus is surrounded by a thick cell wall made of chitin. Furthermore, fungi are unable to perform photosynthesis, thus they are considered heterotrophic organisms.

How does Keplers third law compare the periods and orbital radii of two planets with a solar system?
-the square of the ratio of the periods equals the cube of the ratio of the radii
-the square of the ratio of the periods equals the ration of the radii
-the ratio of the periods equals the square of the ratio of the radii
-the cube of the ratio of the periods equals the square of the ratio of the radii
Answer:
The square of the ratio of the periods equals the cube of the ratio of radii.
Explanation:
German astronomer Johannes Kepler who lived from 1571-1630, gave the three descriptive laws called Kepler's law. He derived this law after he had study and make observations of planetary motion done by Tycho Brahe.
The Kepler's third laws state that the square ratios of the period equals the cube ratio of the distance or radii.
From Kepler's third law, the square of the ratio of the periods equals the cube of the ratio of the radii.
Kepler's third law states that the ratio of the square of an object's orbital period with the cube of the semi-major axis of its orbit is the same for all objects orbiting the same primary.
The law is simplified using mathematical formula as follows;
T² ∝ R³
[tex](\frac{T_2}{T_1})^2 = (\frac{R_2}{R_1} )^3[/tex]
where;
T is the orbital period of the planetR is the radius of the planetThus, we can conclude that from the Kepler's third law, the square of the ratio of the periods equals the cube of the ratio of the radii.

Based on the following pedigree, how is the trait being inherited?
A. sex-linked inheritance
B. complete dominance
C. codominance
D. multiple alleles
Answer:
The correct answer is option B. "complete dominance".
Explanation:
Widow's peak is a trait characterized by the growth of a hairline in the center of the forehead. By looking at the pedigree we can conclude that widow's peak has no sex-linked inheritance because there is father-to-son transmission. There is no codominance or multiple alleles inheritance neither, because there is no slight differences in the trait (people either have or not have widow's peak). We can conclude that widow's peak have a complete dominance inheritance, because in the case where both parents have widow's peak they have a female daughter with no widow's peak. This means that both parents were heterozygous of the widow's peak allele, and since both expressed the trait we can conclude that it is completely dominant.

Which groups are involved in the peptide links of amino acids?
In peptide bond formation, the amino group of one amino acid reacts with the carboxyl group of another, creating an amide bond. The polypeptide chain has a directional structure with a free amino group at the N terminal and a free carboxyl group at the C terminal, crucial for protein function.
Explanation:Amino acids are the building blocks of peptides and proteins, linked together by peptide bonds. The groups involved in forming a peptide bond are the amino group (-NH2) from one amino acid and the carboxyl group (-COOH) from another amino acid. During the formation of a peptide bond, these groups combine in a dehydration synthesis reaction, resulting in the release of a molecule of water and the creation of an amide bond between the two amino acids.
The resulting polypeptide chain has a free amino group at the N terminal and a free carboxyl group at the C terminal. This directional structure is important as the sequence of amino acids, which determines the protein's properties, is read from the N terminal to the C terminal. The unique sequence of amino acids is key to the protein's structure and function after it goes through post-translational modifications to become fully functional.
