Answer:
Explanation:
In a broad sense, the term "genotype" refers to the genetic makeup of an organism; in other words, it describes an organism's complete set of genes. In a more narrow sense, the term can be used to refer to the alleles, or variant forms of a gene, that are carried by an organism
An organism's genotype is its genetic makeup. It is made up of the collection of genes that are inherited from ones parents.
What is genotype?Genotype refers to the composition of an organism. It encompasses the collection of genes that are inherited from ones parents. While the genotype establishes the traits of an organism these traits may not always be evident, in the phenotype.
On the hand the phenotype represents the attributes of an organism, including factors like height, eye color and hair color. Although the genotype plays a role in shaping the phenotype it is also subject to influence, from factors.

Why do bones, shells, and teeth make up most of the fossils that have been found so far?
because bones, shells, and teeth are easier to find
because most organisms have bones, shells, and teeth
because bacteria break down bones, shells, and teeth the fastest
because bones, shells, and teeth decay slower than other body parts
Answer:
the last one
Explanation:
For an organism to become a fossil, it must not decompose or be eaten. ... When an organism is buried quickly, there is less decay and the better the chance for it to be preserved. The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts.

The process of using the chemical energy from food and oxygen molecules to power life processes
Explanation:
In cellular respiration, the organisms combine with and use oxygen and molecules from food to divert thre chemicla energy into life-sustaining processes.
Cellular respiration is the process by which organisms use chemical energy from food and oxygen molecules to power the basic life processes. Thus, the correct option is A.
What is Cellular respiration?
Cellular respiration is the process by which cells in living organisms break down sugar (carbohydrates) and turn it into energy in the form of ATP. This energy is later used to perform work at the cellular level. The purpose of cellular respiration is providing cells with the energy they need to function.
Cellular respiration is a series of chemical reactions to produce ATP. The main stages of cellular respiration include: glycolysis, pyruvate oxidation, citric acid cycle or Krebs cycle, and oxidative phosphorylation.
An example of cellular respiration in plants is the photosynthesis which is used to obtain the glucose needed for cellular respiration. This means that plants can use the light energy they acquire from the sun to yield glucose and oxygen. This glucose is converted to pyruvate by glycolysis.
Therefore, the correct option is A.

A baker has created a new strain of yeast which contains no cytochrome c gene and no cytochrome c protein. this will affect what the yeast strain can do to obtain energy. what will this yeast strain do more of compared to a normal strain
Will this new strain of yeast obtain more or less free energy from glucose in its growing medium?
Answer: Less because cytochrome c is key to the electron transport chain.
Explanation:
The Cytochrome c is an essential component of the electron transport chain. Without this there will be no oxidation and reduction of iron atom will take place which could convert the ferrous ions to ferric ions. Thus the entire process of electron transport chain and energy production in the form of ATP will be compromised. So, there will be no production of energy in the anaerobic fermentation by yeast.
Answer: C. Fermentation
Explanation: The yeast strain will do more fermentation because the cytochrome c protein is what gives the yeast energy and ATP. Without this gene, the yeast strain will need to find a different way to make energy, like fermentation.

Answer:
According to the image shown, the country that most closely resembles the population pyramid by age is the United States (option A).
Explanation:
The population pyramid consists of a bar chart that groups the population by age and sex. Each sex is separated into two columns, while from the base to the top the ages are grouped from lowest to highest.
The pyramid by age shown in the image corresponds to a developed country, such as the United States, since the distribution of the population of infants and young people is proportional, being more acute in the advanced ages, acquiring the shape of a bottle.
The "bottle" shape of the population pyramid indicates a controlled birth rate, as well as good availability of basic and sanitary resources, characteristic of a developed country like the United States.
The other options are not correct because:
C and D. In developing countries such as Nigeria and Ethiopia, the birth rate is high - forming a broad base - and the resources available are limited, so there is a progressive decrease as the age groups are distributed, giving a true pyramid shape.
B. Italy, a European country, has a tendency to rhomboidal population pyramids. This is due to a predominance of adult, young and mature, population, low birth rate, good basic and sanitary resources.
why does the transfer of energy stop?
Answer:
Energy transfer will stop when both objects reach equilibrium
Explanation:
Im guessing you are refering to organism energy for when they consume each other. There is not enough energy left for the organisms to consume. When an organism is eaten, the organism that ate it only get 10% of the energy that the other organism had, therefore after this process happens over and over again there is not enough energy left to even consume.

what are the normal breath sounds?
Answer:release and relex
Explanation:
Answer:
Using a stethoscope, the doctor may hear normal breathing sounds, decreased or absent breath sounds, and abnormal breath sounds.
Absent or decreased sounds can mean:
Air or fluid in or around the lungs (such as pneumonia, heart failure, and pleural effusion)Increased thickness of the chest wallOver-inflation of a part of the lungs (emphysema can cause this)Reduced airflow to part of the lungsYou are conducting a twin study to estimate the heritability of a particular trait and have found that monozygotic twins have a concordance of 75%. Using ONLY this information, does this trait show high, low, or unknown heritability? Write no more than two sentences to justify your conclusion, and/or specify how to use additional information to determine heritability. ITRE
Answer:
The correct answer is "high heritability".
Explanation:
Concordance, is a term used in genetics to describe the probability that one of the twins have certain trait if his brother certainly has it. A high percentage of concordance, such as 75%, is translated into high heritability since monozygotic twins have identical genomic sequences. Additional information to determine heritability will be to study the exposure to similar environmental conditions, since environment can also affect the presence of certain traits.
