2. How might a mutation that causes a single letter change in the DNA sequence affect
your protein structure and function?
Answer:
A mutation that causes a single letter change in the DNA sequence can affect your protein structure and function because the sequence of letters in a gene determines the sequence of amino acids in the protein that it encodes. A single letter change in the DNA alters the mRNA which alters the amino acid sequence of the resulting protein and sometimes that can cause serious results if it changes the way a protein works.

Which of the these do plants NOT obtain using Active transport?
A. Phosphorus
B. Carbon dioxide
C. Potassium
D. Nitrogen
Active transport is the system that requires energy to transport the macro and micronutrients. Carbon dioxide is not transported through active transport. Thus, option B is correct.
What is active transport?Active transport is the mechanism to transport the molecules and the ions from regions of low concentration to higher concentration with the help of the energy as the movement are opposite the gradient.
The macronutrients like phosphorus, nitrogen, and potassium are transported with the help of the transporter molecules across the membrane and utilize ATP. While carbon dioxide diffuses directly and requires no energy.
Therefore, carbon dioxide is transported by passive transport.

HELP!! Orchids are flowering plants that depend on bees for pollination. A population of orchids in a rainforest has reached its carrying capacity. The size of the rainforest's bee population is a limiting factor of the orchid population. What will happen to the orchids' carrying capacity if the rainforest's bee population decreases?
Answer:
The carrying capacity will decrease because the level of the limiting factor decreases.
Explanation:
Decrease in available resources lead to decrease in carrying capacity of an environment for a population. The rainforest's bee population is a limiting factor for orchid population, decrease in bee population will lead to decrease in orchid population.
Hence, the carrying capacity will decrease due to decrease in limiting factor as the number of orchids that can be sustained by the environment would decreases.
When people have their gallbladders removed, their bodies no longer have a place to store bile, and the bile flows from the liver continuously. What effect might this have on their ability to digest fats?
A. There will be very little change since bile will still be present to emulsify fats.
B. Fats will be emulsified more efficiently with the constant flow of digestive enzymes.
C. It will be unlikely that they will be able to emulsify and digest fats.
D. Only small amounts of fats will get digested since high concentrations of bile enzymes are needed for efficient digestion.
Answer:
A. There will be very little change since bile will still be present to emulsify fats.
Explanation:
The gallbladder is a pear-shaped storage sac present in the alimentary canal of humans and functions to store excess bile in between meals. The bile is a greenish-yellow substance composed of different substances like salts, bile pigments, cholesterol etc. The bile is produced in the liver and aids in the digestion of fats.
The gallbladder serves as an intermediary between the organ of bile production (liver) and its destination (intestine). According to the question, once the gallbladder is removed, there is no longer a place to store bile. However, bile will still be produced by the liver and released directly into the intestine instead.
Hence, the bile will still be present to perform its function of emulsifying fats with little changes in the way it is released into the intestine. Note that, the gallbladder only regulates the speed at which the bile is released into the intestine.
Which one of the following steps in elongation is directly dependent on ATP or GTP hydrolysis? Peptide bond formation Movement of the ribosome 3 bases toward the 3’ end of the mRNA Loss of the sigma subunit Binding of initiator tRNA to appropriate AUG codon Translation termination
Answer:
Movement of the ribosome, 3 bases toward the 3’ end of the mRNA
Explanation:
Movement of the ribosome, 3 bases toward the 3’ end of the mRNA - This process can also be referred to as translator in the ríbosome.
This translocation process requires GTP hydrolysis.
Translocation occurs by the action of the enzyme elongation factor which uses the energy resulting from GTP hydrolysis to move to the A site on the small subunit forcing the tRNA and the mRNA to move a distance of one codon ( 3 bases) through the ribosome.
A chromosome’s structure is what it is made of and how it is organized. Its function is what it does. How does knowing about the structure and function of chromosomes help to explain variation in sexually reproducing organisms?
Answer:
Chromosome, the microscopic threadlike part of the cell that carries hereditary information in the form of genes. A defining feature of any chromosome is its compactness. For instance, the 46 chromosomes found in human cells have a combined length of 200 nm (1 nm = 10− 9 metre); if the chromosomes were to be unraveled, the genetic material they contain would measure roughly 2 metres (about 6.5 feet) in length. The compactness of chromosomes plays an important role in helping to organize genetic material during cell division and enabling it to fit inside structures such as the nucleus of a cell, the average diameter of which is about 5 to 10 μm (1 μm = 0.00l mm, or 0.000039 inch), or the polygonal head of a virus particle, which may be in the range of just 20 to 30 nm in diameter.
Intermediate filaments lack the intrinsic polarity of microtubules and microfilaments, because IF tetrameric subunits are symmetric. are grouped into five cytoplasmic classes based on the cell types in which they are found and one nuclear class. are the most stable and least soluble cytoskeleton filaments. are not found in plant cell cytoplasm. All of the above are true.

Calculate the following problem. Remember to round off the answer to the nearest whole number, because fractions of a drop are to be avoided when calculating IV drip rates.
Order: 1000 mL of D51/2NS (dextrose 5% in 0.45% sodium chloride) in 8 hours
Available: 1 liter of D51/2NS (dextrose 5% in 0.45% sodium chloride); IV macrodrip tubing 10 gtt per milliliter
The patient should receive ______ gtt per minute.
Answer:
IV flow rate (ggt/min) required for the patient = 21 ggt/min to the nearest whole number
Explanation:
To calculate IV flow rate or the drops per minute, the drop factor is needed.
The drop factor is the number of drops in one mL of solution, and is printed on the IV tubing package.
The formula for calculating the IV flow rate (drip rate) is given as;
IV flow rate (ggt/min) = {total volume (mL) / time (min)} * drop factor (gtts/mL)
From the given values in the question, drop factor = 10 ggt/mL; time in minutes = 8 hours * 60 minutes/hour = 480 minutes; volume of IV fliud = 1 litre = 1000 mL
Therefore, IV flow rate (ggt/min) = (1000/480) * 10 = 20.33
IV flow rate (ggt/min) required for the patient = 21 ggt/min to the nearest whole number
Which best explains a primary reason for the inability of life to exist in Earth’s early atmosphere? There was insufficient energy from material collisions to change their density. High temperatures during Precambrian time caused surface water evaporation. Volcanic eruptions and comet collisions added different gases to the atmosphere. Available oxygen was used to help create an ozone layer within Earth’s atmosphere.
Answer:
c
Explanation:
on edge
The sentence that best explains the primary reason for the inability of life to exist in Earth’s early atmosphere is " Volcanic eruptions and comet collisions added different gases to the atmosphere".
During the early years of the Earth volcanic eruptions were much more common than they are today. When these volcanoes erupted, they spewed many gases into the atmosphere, including:
Carbon dioxideWater vaporNitrogenHydrogenwhich was directly responsible for the composition of the early atmosphere.
Due to these gases being released into the atmosphere by Volcanic eruptions, causing a severe lack of oxygen, life on Earth was almost unsustainable. It was not until solar radiation and photosynthesis produced oxygen that life became sustainable.

The introduction of certain animals from Europe, especially horses, had a positive effect on some American Indian communities. However, European cattle and other livestock sometimes caused more harm than good. In some cases, livestock entered the unfenced fields of American Indian farmers, eating and trampling their crops. Unlike European farmers, many American Indian farmers had never learned how to fence in their fields because it had never been necessary. The American Indians in the Spanish colony of New Spain in Central and North America experienced this problem. Antonio de Mendoza, the first viceroy of New Spain, wrote these words to the Spanish king in the 1530s: May your Lordship realize that if cattle are allowed, the Indians will be destroyed. How could the Spanish have helped American Indians adapt to the new species of livestock?
Answer:
Explanation:
To reduce the incidents of destruction of field by this animals the Spanish could have helped adapt by taming the animals, the animals can be kept in a ranch where they would be controlled to prevent them from entering fields.
The American India could be enlighten through orientation about how to keep their farms save from invasion by this pest animals.
The India should be enlighten about the animal and its mode of operation and how to prevent the entry of this animal pest into their field. This will help them adapt to animal.
With this the India would be able to feel loved and start adapting to the new changes.
Answer:
The Spanish colonists could have helped the American Indians adapt to the new species of livestock by teaching them to fence their fields to protect their crops. Furthermore, they could have taught American Indians how to use livestock for food, trade, and labor.
