The terms "fluid" and "mosaic" are used to describe the cell membrane. What does each of these terms tell you about the structure of the cell membrane?

Answers

Answer 1

Answer:

The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components —including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character. Plasma membranes range from 5 to 10 nm in thickness...

For example, myelin contains 18% protein and 76% lipid.

Which bond types may be utilized to establish the tertiary structure of a protein?

Answers

The bond types that may be utilized to establish the tertiary structure of a protein are the non-covalent bonds.

The tertiary structure of a protein is the arrangement of a protein in the three dimensional space. It is stabilized by the non-covalent bonds. It is the level of protein structure where a protein becomes functional. The example of protein which is functional in tertiary structure is myoglobin.

Non-covalent bonds are those that are formed between different molecules rather than the atoms. No sharing of electrons occurs in this type of bonding. The examples of these bonds are: ionic bonds, hydrogen bonds, Van der Waals forces, etc.

how much higher is the concentration of minerals in roots than in the soil

Answers

Answer:

hope this helps u bro/broette also a very shiny crown would would be appreciated

Explanation:

The concentration of mineral nutrient elements is higher inside the root-hairs than in the surrounding soil because the absorption of mineral elements from the soil involves active transport by the cells. As the concentration of ions always maintained greater inside the root hair water present in the surrounding soil moves into the roots by osmosis. This dilute solution of water and mineral salts, absorbed from the soil by the roots, can be used for food manufacture in the leaves, only if it can travel up to the highest points of the plant. This upward flow occurs through the xylem.

A. cytosol B. ER lumen C. ER membrane

Answers

The components involved with ER transport matched with the appropriate cellular location is as follows:

1. signal-recognition signal - A. cytosol

2. protein translocator - C. ER membrane

3. mRNA - A. cytosol

4. SRP receptor - C. ER membrane

5. active site of signal peptidase - B. ER lumen

1. Signal-recognition signal (SRS) - located in the cytosol, it is responsible for recognizing and binding to the signal sequence on newly synthesized proteins.

2. Protein translocator - located in the ER membrane, it facilitates the movement of newly synthesized proteins from the cytosol to the ER lumen.

3. mRNA - located in the cytosol, it serves as the template for protein synthesis.

4. SRP receptor - located in the ER membrane, it binds to the signal recognition particle (SRP) and facilitates the transfer of the protein to the protein translocator.

5. Active site of signal peptidase - located in the ER lumen, it cleaves the signal sequence from the newly synthesized protein.

In summary, the components located in the A. cytosol are 1. signal-recognition signal and 3. mRNA. The components located in the B. ER lumen is the 5. active site of signal peptidase. Lastly, the components located in the C. ER membrane are 2. protein translocator and 4. SRP receptor.

How does the sequence of bases on one strand of DNA control the sequence of bases on the complementary strand?



There is only a single strand in a DNA molecule.


The sequences of bases on both strands are always identical.


Adenine on one strand can pair only with thymine on the other strand; cytosine, only with guanine.


The sequences of bases on both strands are not related.

Answers

Answer:

Adenine on one strand can pair only with thymine on the other strand; cytosine, only with guanine.

Explanation:

DNA nucleotides can contain one of four nitrogenous bases. These bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The two strands are held together through hydrogen bonds that form between the nitrogenous bases. Adenine (A) forms bonds with thymine (T) while cytosine (C) forms bonds with guanine (G); A only ever pairs with T, and C only ever pairs with G.

bla

Answers

Answer:

Explanation:

To calculate how much more blood flows per minute to the skeletal muscles during intense exercise than during rest, we need to use the following formula:

exercising - resting = increased blood flow

Substituting the given values, we get:

exercising - resting = increased blood flow

exercising - 1,200 cm³/minute = 4.CC

To solve for exercising, we need to isolate the variable on one side of the equation. Adding 1,200 cm³/minute to both sides, we get:

exercising - 1,200 cm³/minute + 1,200 cm³/minute = 4.CC + 1,200 cm³/minute

exercising = 4.CC + 1,200 cm³/minute

Therefore, the equation to calculate how much more blood flows per minute to the skeletal muscles during intense exercise than during rest is:

exercising = 4.CC + 1,200 cm³/minute

what two things influence an individual's phenotype? read pages 93-100 of the lab manual. complete all of the punnett squares and tables 6.1-6.11 using this simple document

Answers

The roles of genetics and the environment, you can better analyze an individual's phenotype and the factors that influence its expression.

An individual's phenotype is influenced by two main factors: genetics and environment.
1. Genetics: The genetic material inherited from both parents, consisting of genes, determines the individual's genotype. These genes interact and express themselves in the form of observable traits, which constitute the phenotype. By completing Punnett squares (as mentioned in tables 6.1-6.11 in the lab manual), you can predict the potential genotypes and phenotypes of offspring based on their parents' genetic information.
2. Environment: The conditions and circumstances in which an individual lives can also impact their phenotype. Factors such as nutrition, exposure to sunlight, and other external factors can influence the expression of certain traits.
To analyze an individual's phenotype, you can follow these steps:
1. Read pages 93-100 of the lab manual to understand the concepts and terminology related to genetics and phenotypes.
2. Use the Punnett square method to predict genotypes and phenotypes by cross-referencing the parents' genetic information.
3. Complete all of the Punnett squares and tables (6.1-6.11) in the lab manual to practice applying this knowledge.
4. Consider environmental factors that could influence the expression of traits, such as nutrition or sunlight exposure.
By understanding the roles of genetics and the environment, you can better analyze an individual's phenotype and the factors that influence its expression.

how does natural selection explain the variety of flower colors in the china rose?

Answers

When a plant population shifts from being predominantly hummingbird-pollinated where flowers are red, to hawkmoth-pollinated, natural selection works to change the flower color to white or yellow.

Natural selection is the variation in individual survival and procreation brought on by phenotypic variances. The evolution of a population's heritable features across generations is a fundamental mechanism of evolution.Natural selection is the theory behind evolution put forth by Charles Darwin. Given the scarcity of resources in nature, animals with heritable features that promote survival and reproduction will typically produce more offspring than their contemporaries, leading to an increase in the frequency of such traits across successive generations.

bacteria AUAGAUGG
eukaryote AAAGAAGG
archaea AAUGGAGU

g what two methods are commonly used for separating a mixed culture of bacteria? multiple choice 3 pour plating; gram staining streak plating; pour plating streak plating; smear preparation streak plating; simple staining

Answers

The two methods commonly used for separating a mixed culture of bacteria are streak plating and pour plating.

The two commonly used methods for separating a mixed culture of bacteria are streak plating and pour plating.  Streak plating involves the use of an inoculating loop to streak the bacterial mixture onto an agar plate in a pattern that gradually thins out the bacteria. This method allows for the isolation of individual bacterial colonies, as the bacteria are spread out across the plate, and subsequent growth occurs in distinct colonies.

Pour plating, on the other hand, involves mixing the bacterial culture with molten agar and then pouring the mixture into a petri dish. The agar solidifies, trapping the bacteria within it. Dilutions of the mixture are typically used to achieve individual colonies. Both methods provide a means to separate and isolate bacteria from a mixed culture, enabling further study and characterization of specific bacterial strains.
