What is the function of the conjugation pilus?.

Answers

Answer 1
Conjugative pili allow the transfer of DNA between bacteria, in the process of bacterial conjugation. They are sometimes called “sex pili”, in analogy to sexual reproduction, because they allow for the exchange of genes via the formation of “mating pairs”.

whats the difference between starch paste and starch milk(long ish answer pls)

Answers

Answer:

Starch Paste is basically a mixture of cellulosic materials added by wheat starch and rice. Starch Milk is just milk with starch in it.

Explanation:

Hope this helps!

Starch paste and starch milk are different in their constituents as starch paste contains a mixture of cellulose which is added to rice or wheat whereas starch milk is just raw starch with fibers in it.

What are starch paste and starch milk?

Starch paste is a water-soluble adhesive which is primarily used to bond the sheets of paper. It is widely used in paper industry. It is made from the starch of the grains, potatoes, or other plants that are easily available. Before hardening of this paste, starch paste is a highly viscous, gel-like mixture with high moisture content. The starch paste based adhesives adhere well to the cellulosic materials hence used widely in industries.

The waste product formed from the mashed potatoes smuggling with water i.e., the dewatered potato pulp is known as the starch milk. Starch milk is contaminated by small fiber particles such as potato fragments and all the remaining components of potato juice. The starch milk is therefore also known as the raw starch milk.

There are over 1300 imperilled species in the United States. 33.4% has been caused by introduced species or more so invasive species

The invasive or introduced species in the United States has seen an economic impact since the damage can be seen in both animals and plants. Now with an invasive species brought about, the naturally occurring species are left fighting for a spot in the habitat and lose in most cases. So economically, the United States has to spend money to get rid of the invasive species

Some of the invasive species have been known to live all year long, and so during the winter seasons, they act as food sources to birds and other animals.

Answers

Answer:

Three States of Matter

 

 

Learning Objective

Describe the three states of matter

Key Points

Matter can exist in one of three main states: solid, liquid, or gas

The states of matterThis diagram shows the nomenclature for the different phase transitions.

Solids

A solid’s particles are packed closely together. The forces between the particles are strong enough that the particles cannot move freely; they can only vibrate. As a result, a solid has a stable, definite shape and a definite volume. Solids can only change shape under force, as when broken or cut.

In crystalline solids, particles are packed in a regularly ordered, repeating pattern. There are many different crystal structures, and the same substance can have more than one structure. For example, iron has a body-centered cubic structure at temperatures below 912 °C and a face-centered cubic structure between 912 and 1394 °C. Ice has fifteen known crystal structures, each of which exists at a different temperature and pressure.

A solid can transform into a liquid through melting, and a liquid can transform into a solid through freezing. A solid can also change directly into a gas through a process called sublimation.

Liquids

A liquid is a fluid that conforms to the shape of its container but that retains a nearly constant volume independent of pressure. The volume is definite (does not change) if the temperature and pressure are constant. When a solid is heated above its melting point, it becomes liquid because the pressure is higher than the triple point of the substance. Intermolecular (or interatomic or interionic) forces are still important, but the molecules have enough energy to move around, which makes the structure mobile. This means that a liquid is not definite in shape but rather conforms to the shape of its container. Its volume is usually greater than that of its corresponding solid (water is a well-known exception to this rule). The highest temperature at which a particular liquid can exist is called its critical temperature.

A liquid can be converted to a gas through heating at constant pressure to the substance’s boiling point or through reduction of pressure at constant temperature. This process of a liquid changing to a gas is called evaporation.

Gases

Gas molecules have either very weak bonds or no bonds at all, so they can move freely and quickly. Because of this, not only will a gas conform to the shape of its container, it will also expand to completely fill the container. Gas molecules have enough kinetic energy that the effect of intermolecular forces is small (or zero, for an ideal gas), and they are spaced very far apart from each other; the typical distance between neighboring molecules is much greater than the size of the molecules themselves.

A gas at a temperature below its critical temperature can also be called a vapor. A vapor can be liquefied through compression without cooling. It can also exist in equilibrium with a liquid (or solid), in which case the gas pressure equals the vapor pressure of the liquid (or solid).

A supercritical fluid (SCF) is a gas whose temperature and pressure are greater than the critical temperature and critical pressure. In this state, the distinction between liquid and gas disappears. A supercritical fluid has the physical properties of a gas, but its high density lends it the properties of a solvent in some cases. This can be useful in several applications. For example, supercritical carbon dioxide is used to extract caffeine in the manufacturing of decaffeinated coffee.

Phase Changes –What does a phase change look like at the molecular level? This video takes a look at the molecular structure of solids, liquids, and gases and examines how the kinetic energy of the particles changes. The video also discusses melting, vaporization, condensation, and freezing.

Leucine

Explanation:

Leucine amino acid is represented by the codon UUA.  One codon codes for only one amino acid.

What are amino acids?

Proteins are made up of substances called amino acids. Proteins and amino acids are the components of life. Amino acids are the byproducts of the digestion or breakdown of proteins. Amino acids are used by the human body to create proteins that aid in breaking down food.

There are 20 amino acids, of which 10 amino acids are essential and 10 are non-essential amino acids.

Codons made from three nitrogenous bases codes for amino acids. One amino acid can be coded by more than one codon, while one codon can code only one amino acid. For example, UUA codes only for leucine, but leucine can be coded by UUA, UUG, CUA, CUC, CUG, and CUU.

c. Neither parent carries the allele for color blindness.
d. The father carries the allele for color blindness.
e. The mother carries the allele for color blindness.​

Answers

B is the answer
If it’s a recessive allele 1 parent isn’t enough, both parents have to have the recessive allele, and even then it’s a small chance. Hope this helped ^^

What is a Recessive trait?

A recessive trait is usually expressed when there is the presence of two

recessive alleles in an individual or organism. A dominant  trait on the other

hand can be expressed with the organism having only one dominant allele

In this scenario, the red green color is a recessive trait

and the offspring produced is color blind which basically means that both

parents carry the allele for color blindness.

What is the role of density changes in a convection cycle

Answers

Answer:

Convection is heat transfer due to a density differential within a fluid. As water's temperature increases in the presence of a heat source, it will become less dense and rise. As it moves up and away from the heat source, it cools and becomes more dense and sinks. ... Air from above the ocean is colder and more dens

Convection is the transfer of heat caused by a density difference within a fluid. Water becomes less dense and rises as its temperature rises in the presence of a heat source.

What is convection?

Convection is a method of moving heat that is also known as a heat transfer mechanism. When a fluid, such as air or water, is in motion, heat is transferred. Temperature differences across the fluid drive convection.

Differential heating causes convection currents. Warmer (less dense) material rises, while cooler (more dense) material sinks.

This movement is responsible for the formation of circulation patterns known as convection currents in the Earth's atmosphere, water, and mantle.

Convection is the heat transfer resulting from variations in density within a fluid. In the presence of a heat source, water becomes less dense and rises in density.

Thus, this is the role of density changes in a convection cycle.
