Suppose you want to make a new connection to species in the concept map. Which of the terms below could fill in the blank in this new connection: "_____ is a mechanism that defines the separation between species." Select all that apply.
Answer:
Hello. You did not enter answer options, but some terms that can be used to fill in the blank are:
Hybrid infertility, Hybrid inviability, Behavioral isolation, Sympatric isolation, Habitat isolation, Hybrid breakdown, Allopatric isolation.
Explanation:
All of the above terms represent situations that cause separation between species. This separation can occur physically or molecularly, but it always results in genetic modifications that end up separating one species genetically from the other, causing evolution and generating different species, to the point that it is not possible to establish mating between its members.
Sabita is a mother in Nepal. She lives in poverty in the Western part of the country with her two children. Everyone in her family has some degree of malnutrition or nutrient deficiency. Match each of the following deficiency diseases with its corresponding nutrient.
a. Sabita is blind from a diet devoid of fortified milk, animal products, or dark yellow and orange fruits and vegetables.
b. Sabita has an enlarged thyroid gland due to a dependence on unfortified salt.
Nutrient:
1. Iron
2. Vitamin A
3. Vitamin D
4. Iodine
Answer:
a. Sabita is blind from a diet devoid of fortified milk, animal products, or dark yellow and orange fruits and vegetables. - Vitamin A
Sabita is suffering from Vitamin A deficiency. A lack of Vitamin A usually shows itself with night blindness but can cause complete blindness if not acted upon quickly.
Vitamin A deficiency is quite common in developing or poorer nations such as the area Sabita is located and usually attacks children of women in their reproductive stage. Sources of vitamin A include; fortified milk, animal products and fruits and vegetables.
b. Sabita has an enlarged thyroid gland due to a dependence on unfortified salt. - Iodine
Iodine deficiency leads to an abnormal enlargement of the thyroid gland leading to a condition known as Goiter which presents itself as a big bulge in a person's neck. Iodine is usually placed in fortified salt along with iron to reduce iodine deficiency so Sabita's dependence on unfortified salt is robbing her of a great source of Iodine.
The condition in which the body is deprived of minerals, vitamins and other macro and micronutrients are called malnutrition.
The correct matches and their explanation are as follows:
a. The correct answer is:
Option 2. Vitamin A
Sabita is blind from meals deficient in fortified milk, animal products, fruits and vegetables due to Vitamin A deficiency.Night blindness is a common symptom of a Vitamin A deficiency.It is most common in developing regions due to the lack of proper meals. The best source of vitamin A is milk, fruits and animal products like eggs.b. The correct answer is:
Option 4. Iodine
Sabita has a swollen thyroid gland due to habituation on unfortified salt deficient in Iodine.Iodine deficient diet causes thyroid gland enlargement a disease called Goiter. This type of disease also affects glucose metabolism and weight.To learn more about malnutrition and diet follow the link:

Answer:
1. Lac P or the promoter is the binding site for RNA polymerase, situated just upstream to the gene.
2. Lac O or operator is a sequence situated just downstream to the sequence of the promoter at which binding of the repressor protein is done and ceases RNA polymerase enzyme from binding.
3. Lac Z refers to the gene that encodes for protein beta-galactosidase, which further results in the formation of glucose and galactose from lactose.
4. For high expression in E.coli IPTG is required. It attaches with the lac repressor and discharges the tetrameric repressor from the lac operator in an allosteric fashion, thus, permitting gene transcription in the lac operon.
5. AmpR is also known as the ampicillin-resistant gene, which is utilized as a selective marker for selection against ampicillin antibiotic.

An area classified as a temperate deciduous forest begins to experience a lack of rainfall that lasts for many years. Given enough time, if the area continues to experience a lack of rainfall, it will eventually become:__________a. savanna.b. temperate rainforest.c. shrubland, grassland, or woodland.d. taiga.
Answer:
Savanna
Explanation:
Lack of rainfall over a period of time may convert a temperate deciduous forest into a Savanna.
Grasslands are characterized by a domination of grasses rather than large shrubs or trees. Savanna is a grassland with a few scattered individual trees. Savannas are always found in areas that are quite hot. The annual rainfall in a typical savanna may range from about 76.2-101.6 cm. Some savanna regions may receive as low as 15.24 cm -25.4 cm of rain in a year, followed by a long period of drought when fires can occur.

Draw a cross section of a peach, and label the structures. What parts of the flower give rise to these structures
Answer:
exocarpo is synonymous with exocarp
endocarpo is synonymous with endocarp
mesocarpo is synonymous with mesocarp
semilla is synonymous with seed
Explanation:
In phase one, the plant's ovary begins to grow abruptly, this is where the embryo and endosperm affect their size, but if this ovarian growth is interrupted by an external factor, it determines the size of the future.
Then, the embryo and the endosperm could grow and undergo a process called sclerification, which is the hardening of the interior of the fruit, that is to say, the future formation of the seed or vulgarly called "pit". .
After this, the mesocarp, which is what is called the fleshy body or subglobose edible drupe, begins to grow.
The growth of the mesocarp is what gives the volume, weight and body to the fruit, so that after maturation it exceeds the strength of the branch and it falls from the tree.

Answer:
positive error and negative error.
Explanation:
There are two types of error which is possible when measuring of a length with the help of ruler. Positive error occurs if the calculated value is larger than actual value while negative error occurs when the calculated value is smaller than actual value. To avoid positive error, the increased value should be subtracted from calculated value while negative error can be corrected by adding the value with the reading.
A couple has just learned their neonate is diagnosed with osteogenesis imperfecta, and they
ask, "What caused our child to get this disease?" What should the health care provider teach
the couple about their neonate's condition?
Answer:
osteogenesis imperfecta is an inherited genetic disease that mainly affects the bones.
Explanation:
Osteogenesis imperfecta is an inherited genetic disease associated with alterations in collagen synthesis, which have been shown to increase the risk to suffer bone fractures. This genetic disorder is characterized by different health problems including, among others, fragile bones, reduced skeletal mass, skin hyperlaxity, malformations in the central nervous system, etc. Clinically, osteogenesis imperfecta must be managed by an interdisciplinary medical team, since patients may present a clinical picture ranging from mild to lethal. In the first place, it is imperative to provide health care to avoid fractures, exercises to maintain muscle mass, exercise to improve motor skills, skincare by specialized dermatologists, etc.
The disease 'osteogenesis imperfecta' is caused by the neonate inheriting it
from either of the parent because it's a genetic disorder. The health care
provider should teach the parent about how to prevent the effect of having
such disease such as bone fractures.
Osteogenesis imperfecta is a genetic disorder inherited by offspring from
their parent. The disease involves individuals having very brittle bones which are easily broken. The nurse should teach the parent to adopt bone strengthening steps such as adequate calcium intake and physiotherapy.

population of squirrels live together in forest an event occurred that caused the population to diverge into two different species over a long period of time which of the following is most likely the event occurred
A natural disaster.
Explanation:
A natural disaster would most likely have occurred to have the population of squirrels completely diverge from each other in order for them to become two separate species.
If a tornado, flood, earthquake, or another type of a natural disaster were to happen, it may have caused drastic damage to the ecosystem and environment of the squirrels. This would most likely cause the squirrels to split up, or diverge from each other and go to separate places in search of a new home.
Over time, these squirrels will reproduce with their own group. Each new group of squirrels, as they are both in different environments now, will have different adaptations from each other. This will eventually make it so they will never be able to reproduce with each other again if they were to meet, as they are now completely different species of squirrel.

Which occurs when the body responds to the environment by maintaining a stable internal environment despite changing
external conditions?
spontaneous generation
homeostasis
growth and development
reproduction
Answer:
homeostasis
Explanation:
Homeostasis is the biological process by which living organisms maintain a stable internal environmetal condition despite changes in their external environment. Homeostasis is an important phenomenon for the optimal functioning of any living organism.
A vivid example of homeostatic process is the regulation of temperature in humans or some animals. Self-r regulating mechanisms help keep their temperature at a stable state irrespective of temperature changes in the external environment i.e. hot or cold external conditions. The steady state of internal temperature is very important for some physiological processes in living systems.

Suppose an experimenter becomes proficient with a technique that allows her to move DNA sequences within a prokaryotic genome. If a researcher moves the repressor gene (lacI), along with its promoter, to a position at some several thousand base pairs away from its normal position, which of the following results would be expected?
A) The repressor will no longer bind to the operator.
B) The repressor will no longer bind to the inducer.
C) The lac operon will be expressed continuously.
D) The lac operon will function normally.
Answer:
D) The lac operon will function normally.
Explanation:
The promoter area can be described as the area that causes the transcription to initiate for a particular gene. Promoters may be near the genes from which they initiate transcription or they may display multiple scenes upstream. The lock operon works normally because the promoter area can still enable transcription on many base pairs. Detects repression promoter and works normally.so correct option is D) The lac operon will function normally.
If a researcher moved the repressor gene of lac I, along with its promoter; the lac operon will function normally. Option D is correct.
Promotor:
It is the genetic sequence that is recognized by the RNA polymerase to start the transcription.
Here, researcher moved the repressor gene of lac I , along with its promoter.
Therefore, transcription starts, it will express the repressor gene also because repressor gene was moved with promotor.

In the box provided explain why living organisms contain more hydrogen atoms than any other atoms yet 65% of a typical organisms mass is oxygen
Answer:
The prime reason for this is that an atom of oxygen comprises sixteen times more mass in comparison to a hydrogen atom.
Explanation:
This means that A orginasim will appear to contain more oxygen, but the size diffrence will mean that there will be more hydrogen, just of a smaller size with less mass, thus making up a lesser part of the organism in terms of mass, but the majority on the molecular level.
Answer:
Reason 1: The mass of Oxygen is 16 times that of Hydrogen. Hydrogen takes 16 atoms to equal the mass of 1 Oxygen atom.
Reason 2: A large portion of an organism’s mass is in the form of water. Water contains two hydrogen atoms and one oxygen atom.
