What is the purpose of using a pedigree?
to study the causes of traits that are acquired during an organism's life
to understand patterns of inheritance in organisms
to determine mating patterns in organisms
to identify traits that are acquired during an organism's life'
Answer:
B) to understand patterns of inheritance in organism
Explanation:
The pedigree's purpose is to understand patterns of inheritance in organism. Examination of the pedigree utilizing the standards of Mendelian legacy can decide if a characteristic has an overwhelming or passive example of legacy. Families are frequently built after a relative harrowed with a hereditary issue has been distinguished.
The purpose of using a pedigree is to understand patterns of inheritance in organisms. Therefore, the correct statement is option B.
What is a pedigree?A pedigree is a diagram showing the relationships between family members and their inheritance of specific traits. The pedigree of a family is studied from which scientists can analyze the patterns of inheritance for a particular trait, which can be dominant or recessive, and the inheritance of trait from one generation to the next generation.
Pedigrees identify individuals who may have any genetic disease or trait, and can predict the particular trait in future generations also, Scientists also understand the inheritance of complex traits controlled by multiple genes and environmental factors.
Pedigrees are used in human genetics for studying the inheritance of genetic diseases and inheritance patterns in other organisms, such as plants to better understand the genetic basis of traits.
Therefore, the purpose of using a pedigree is to understand patterns of inheritance in organisms.

Which statement best describes a keystone species?
O A. Its birthrate is the highest of all the species in the community.
B. It has the highest amount of genetic diversity in the community.
C. It serves as a predator of many other species in the community.
D. Its extinction would cause a significant change in the community.
Answer:
D. Its extinction would cause a significant change in the community.
Explanation:
A keystone species is a species that helps define an entire ecosystem. If its keystone species disappeared, the ecosystem would significantly change or even disappear, too.
There are several types of keystone species:
Predators - they help control the populations of other species, e.g. sharks.Engineers - they create, change, or destroys a habitat, e.g. beaver.Mutuals - two or more species interact for each other’s benefit, e.g. bees and flowers.Based on this information, we can conclude that the correct option is D.
Which of the following is the same as 1 gram?
O A. 10 g
O B. 10 cg
O C. 10 dg
O D. 10 kg
10 dg is same as 1 gram. So, the correct option is (C).
What is Unit conversion?Units of measurement are needed to measure the following quantities like speed, velocity, weight, temperature, etc. when the units of measurement used for measurement are based on preference and convenience as well as standards prescribed for certain processes and applications. does not eat , Converting such units to the extent that they can be directly understood and applied properly.
For accuracy and to avoid confusion in measurement, we convert one unit to another unit like we do not measure the length of a pencil in kilometer. In this case, kilometers (km) have to be converted into centimeters (cm).
Some unit conversions are:
1 kilometer = 1000meters
1 kilogram= 1000grams
1gram = 0.1cg or 1dg (cg= centigrams and dg=decigrams)
Thus, 10 dg is same as 1 gram. So, the correct option is (C).

Answer:
respiration
Explanation:
Which part of the cell does this illustration represent?
A. Mitochondria
B. Golgi apparatus
C. Endoplasmic reticulum
D. Vacuoles
Answer:
The answer is mitochondria
Explanation:
miticondria is the power house
Cellular respiration occurs in mitochondria which is the powerhouse of the cell and produces ATP using chemical energy found in glucose.
What is cellular respiration?
It is the process by which sugar is broken down and turned into energy by the cells in plants and animals. The energy produced is then used to perform work at the cellular level.
Why it is called cellular respiration?
The cells seem to respire in a way that takes in oxygen and leaves out carbon dioxide, ATP and water as an end product.
The three main steps of cellular respiration include
GlycolysisKrebs cycle (citric acid cycle)Electron transport system Oxidative phosphorylation)Glycolysis occurs in the cytoplasm, The citric acid cycle (Krebs cycle) occurs in the mitochondrial matrix and Oxidative phosphorylation occurs in the inner mitochondrial membrane.
Cellular respiration can occur both aerobically(using oxygen) or anaerobically(without oxygen).
Most of the ATP produced by aerobic cellular respiration is made by oxidative phosphorylation. It provides cells with the energy they need to function.
During cellular respiration, one glucose molecule is metabolized to yield 38 ATP molecules.

A species of hawk occupies the same niche in a forest that a species of falcon occupies in a nearby forest. What would be the most likely result if members of the hawk population were introduced to the falcon's forest? (3 points) Either the hawks or the falcons would die off or move away. The falcons would kill the hawks. The hawks would adopt a new diet. The falcons and hawks would coexist in the forest.
Answer:
Either the hawks or the falcons would die off or move away.
Explanation:
Ecological niche refers to the role an organism plays in an ecosystem, which includes how it obtains food, how it interacts, mating etc. two organisms CANNOT occupy the same ecological niche, according to the COMPETITIVE EXCLUSION PRINCIPLE. This is attributed to competition among both species, which will cause one to outcompete the other.
In this case, a species of hawk occupies the same niche in a forest that a species of falcon occupies in a nearby forest. This means that both species of birds (falcon and hawk) cannot coexist or love together. Hence, either the hawks or the falcons would die off or move away.
A scientist conducted an experiment to determine the effect of environment on the color of fur of a himalayan rabbit. the himalayan rabbit typically has a white coat except for its colder nose, feet, tail, and ears, which are black. the black hair allows the rabbit to absorb more heat and keep these extremities warm. the scientist shaved an area of hair on the back of each rabbit, then placed an ice pack over the shaved area on only rabbit
a. the scientists kept the area chilled with an ice pack until the hair had grown back on both rabbit's backs.
The question is incomplete as the figure and question part is missing, however, the figure is attached with the answer and question as follows:
what is the independent variable in this experiment?
What is the hypothesis she is testing?
Rabbit B essential to this experiment?
Answer:
The correct answers are:
The ice (temperature is the variable).
The fur of the Himalayan rabbit changes color with temperature.
Rabbit B is the control group. An experiment without control has no value because the cause of the change cannot be determined.
Explanation:
In this experiment, the researcher is finding the effect of the temperature on the color of the fur to find this she needs a hypothesis which is The fur of the Himalayan rabbit changes color with a change in the temperature.
To test this she needs to have manipulated the temperature which is the independent variable her and she used the ice to manipulate it so the independent variable is ice. The rabbit B has not got any type of treatment as rabbit A gets so it is the control group that is used to compare it with the experimental group.

what is the correct order for the levels of organization in living systems from the simplest to the most complex
Answer:
The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
Explanation:
Living things are highly organized and structured, following a hierarchy that can be examined on a scale from small to large. The atom is the smallest and most fundamental unit of matter. It consists of a nucleus surrounded by electrons. Atoms form molecules which are chemical structures consisting of at least two atoms held together by one or more chemical bonds. Many molecules that are biologically important are macromolecules, large molecules that are typically formed by polymerization (a polymer is a large molecule that is made by combining smaller units called monomers, which are simpler than macromolecules). An example of a macromolecule is deoxyribonucleic acid (DNA), which contains the instructions for the structure and functioning of all living organisms.
