Answer:
increased; almost 100%
Explanation:
The peppered moth witnessed a change in its color and the number at the end of the eighteenth century. The reason behind this was the Industrial Revolution that led to an increase in air pollution. With the increase in air pollution, the dark-colored moths increased in the number. Later, when air pollution decreased, the light-colored moths started to predominate. It was in 1895 that the number of dark-colored moths increased to the maximum.

Lipids, like those in butter, can be broken down into the simple substance that make them up called? A.starches
B.amino acids
C. Carbohydrates
D.fatty acids
Lipids, like those in butter, can be broken down into the simple substance that make them up called fatty acids. Thus, option D is correct.
What are fatty acids ?A saturated or unsaturated fatty acid is a carboxylic acid with an aliphatic chain in chemistry, particularly biochemistry. Fatty acids are a major component of the lipids (up to 70% by weight) in some species, such as microalgae.
But in other organisms, they are not found in their standalone form but rather exist as three main classes of esters: cholesterol esters, phospholipids, and triglycerides Fatty acids are important structural components of cells and important fuel sources for animals in any of these forms.

Which organelle is responsible for packaging and sending out proteins to their proper destinations? Choose 1 answer: (Choice A) A Mitochondria (Choice B) B Golgi body (Choice C) C Nucleus (Choice D) D Lysosome
Answer:
(Choice B) Golgi Body
Explanation:
The rough endoplasmic reticulum works with the Golgi apparatus to move new proteins to their proper destinations in the cell.
The Golgi body is in charge of storing proteins from the rough endoplasmic reticulum in membrane-bound vesicles, which are small lipid bilayer storage units that move molecules to the cell membrane, hence option B is correct.
What is the Golgi body?In all eukaryotic cells, the cytoplasm a gel-like fluid retained in the cell membrane contains a stack of membranes that make up the Golgi apparatus (i.e., complex cells).
Camillo Golgi, who discovered a reticular structure in the cytoplasm of several cell types using silver chromate staining, gave the Golgi apparatus (also known as Golgi to its admirers), its first official name in 1888.
Therefore, the nucleus and rough endoplasmic reticulum are frequently located nearby, an organelle involved in protein synthesis, hence option B is correct.

Which of the following is a property of life shared by prokaryotic cells and eukaryotic
cells, but not viruses?
Answer:
Explanation:
. The ability to process energy through metabolism. viruses cant reproduce without a host cell either
Viruses do not possess the tendency to process energy via metabolic reactions.
Difference between viruses and other cells:Viruses are acellular, that is, they do not comprise any cellular organelles, and fail to divide and grow by its own.
Due to this viruses fail to carry out any kind of metabolic reactions, on other hand, prokaryotes and eukaryotes possesses the tendency to perform independent metabolism.
As viruses are not cells, they can only replicate and assemble within a living host cell, which can be a prokaryote or an eukaryote.
Thus, viruses cannot carry any kind of metabolic reactions while prokaryotes and eukaryotes can.

Carlos noticed a large population of anoles in the park across from his school. The anoles are a variety of colors and sizes. Carlos decided to measure the anoles. He believed that the brighter colored anoles are smaller than the darker colored anoles. His results are below:
Answer:
This question is incomplete; the missing fragment of the question is:
The results are as follows:
12.9 neon, 13.8 neon, 13.9 dark, 14.2 brown, 14.2 blue, 15.5 neon, 15.6 gray, 15.8 gray, 16.1 blue
Did Carlos' data support his hypothesis?
The answer is NO
Explanation:
According to the question, Carlos observed a large population of anoles, which are a variety of colors and sizes in the park across from his school. He then decided to measure the anoles.
However, he hypothesized that: the brighter colored anoles are smaller than the darker colored anoles. In his results, he measured the following sizes for each color of anole:
12.9 neon, 13.8 neon, 13.9 dark, 14.2 brown, 14.2 blue, 15.5 neon, 15.6 gray, 15.8 gray, 16.1 blue
Based on this data, the hypothesis IS NOT SUPPORTED BY THE DATA. This is because the measurements contained same color of anoles that varied in size. If his hypothesis were correct, anoles of the same color should have the same size when measured.

The two primary components of a septic system are a septic tank and a/an _______. Groundwater that comes to the surface naturally is known as a/an _______.
Answer:
nitrates; cone of depression; confined; water table; unconfined; drainage field; spring.
Explanation:
Nitrogen-fixing bacteria in soil can convert excess nitrogen into nitrates, which can contaminate groundwater.
A cone of depression forms around a well when the water table begins to slope toward the well.
The water in an artesian well comes from a confined aquifer.
A well not only has to reach the water table but also has to go deeper.
Unconfined aquifers are more prone to pollution.
The two primary components of a septic system are a septic tank and a drainage field.
Groundwater that comes to the surface naturally is spring.

The change in allele frequencies that occur due to the colonization of a new location by a small group of individuals is called
Answer:
Founder effect.
Explanation:
The founder effect is a case of genetic drift in which a small population sample of a limited number of individuals is shed from a larger population, its gene pool carrying only a part of the genetic diversity represented in the source population. Thus, it is likely that the genetic destinies of the population of origin and of the new population are established in different ways. When a new generation has randomly distributed alleles, with a large enough sample size, we can expect that the gene pool of the new generation will more or less represent the gene pool of the previous generation.

Cell is a basic unit of any living organism. A tissue consists of many cells. Several tissues make up an organelle. Many organelles contribute to a system
The human body parts in order from the simplest level of organization to the most complex is: red blood cell → heart tissue → circulatory system. Thus, the correct option is C.
What is Body organization?The human body is organized at different levels. The basic level from where the organization starts is the cell. Cells are the basic unit of life. They are organized into tissues, and tissues are further organized to form organs. Different organs are organized into the organ systems such as the reproductive system, respiratory system, and muscular systems.

A) Identify and describe the four levels of protein structure.
The four levels of protein structure are the
primary, secondary, tertiary, and quaternary structures.Primary structure: The Primary structure is the basic sequence of amino acids that form a polypeptide chain. There are basically 20 amino acids in a protein.
Secondary structure: This is the regular pattern of folding in the basic structure of a protein. The foldings occur as the alpha and beta sheets.
Tertiary structure: This is the 3 dimensional folding of the polypeptide chain as found in most enzymes.
Quaternary structure: This protein structure is formed from two or more polypeptide chains. The hemoglobin molecule is an example.
