suggest two other features in which the sugarcane flower might different from insect pollinated flower
Answer:
Explanation:
Sugar cane is wind pollinated so the pollen is light weight, non-sticky, flowers producing pollen and ovules are extended above the plant so the pollen can be easily picked up by the wind and filtered out of the wind by the stigmas of the "female."

How is energy tansferred between stages of the carbon cycle?
Why must the ribosomal subunits, made in the nucleolus, assemble in the cytoplasm
and not inside the nucleus?
(a) Because translation occurs in the cytoplasm
(b) Actually, the ribosome IS fully assembled inside the nucleus
(c) So that the subunits can fit through the nuclear pores, given that if the
ribosome is assembled inside the nucleus, the fully assembled ribosome would
not fit through a nuclear pore
(d) None of the above
what is the base-pair rule for a DNA strand matching an RNA strand?
Explanation:
The base pairing of guanine (G) and cytosine (C) is just the same in DNA and RNA. So in RNA the important base pairs are: adenine (A) pairs with uracil (U); Guanine G() pairs with cytosine (C).
The Chargaff rule only holds true for DNA. Base pairing doesn't take place since RNA is single-stranded. Consider a DNA strand.
What make base pair unique in DNA and RNA?Compare the two DNA strands' base-pair rules to this one. Since uracil is absent from DNA, T and A complement one another. In contrast, T bonds with A and A bonds with U in a DNA/RNA match.
Important: It serves as the foundation for base pairing. This rule can be used to both determine the DNA strand length and if a base is present in the molecule.
Adenine and thymine are always equal, and cytosine and guanine are also always equal, allowing us to calculate the percentages of each base.
It assists in figuring out the makeup and structure of DNA in various species. It is constant within a species.
Therefore, the base-pair rule for a DNA strand matching an RNA strand.

Why do paleontologist study fossils ?
Answer:
Paleontologists study fossils so that we can understand the evolution's from past species to the current ones. It also opens a window to discovering exactly how long earth has been around by finding out the age of the fossil itself. Though paleontology has been in the decline recently, and i'm sure we haven't found out all we need to know from these fossils.

What effect do ocean currents have on a biome?
Answer:Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.

Air at 1 atm was closed into a rigid container. It was then heated to a temperature of 911
K. The pressure inside the container was measured to be 2.7 atm. What was the initial
temperature of the gas (in Kelvin)? Round answers to the ones place.
Answer:
Final temperature, T2 = 2460 Kelvin.
Explanation:
Given the following data;
Initial pressure = 1atm
Final pressure = 2.7atm
Initial temperature = 911K
To find the final temperature, we would use Gay Lussac's law;
Gay Lussac law states that when the volume of an ideal gas is kept constant, the pressure of the gas is directly proportional to the absolute temperature of the gas.
Mathematically, Gay Lussac's law is given by;
[tex] PT = K[/tex]
[tex] \frac{P1}{T1} = \frac{P_{2}}{T_{2}}[/tex]
Making T2 as the subject formula, we have;
[tex] T_{2}= \frac{P_{2}}{P_{1}} * T_{1}[/tex]
Substituting into the equation, we have;
[tex] T_{2}= \frac{2.7}{1} * 911[/tex]
[tex] T_{2}= 2.7 * 911 [/tex]
Final temperature, T2 = 2459.7 ≈ 2460 Kelvin.

Explanation:
Fruit flies (Drosophila melanogaster) with a wild-type phenotype have gray bodies and red eyes. Certain mutations can cause changes to these traits. Mutant flies may have a black body and/or cinnabar eyes. To study the genetics of these traits, a researcher crossed a truebreeding wild-typed male fly with a true-breeding female fly with a black body and cinnabar eyes. All of the F1 progeny displayed a wild type phenotype. Which of the following is correct about the traits observed?a. Gray body and cinnabar eyes are dominant.b. Eye color is sex-linked.c. Body color is sex-linked.d. Gray body and red eyes are dominant.
Answer:
d
Explanation:
The correct answer would be that gray body and red eyes are dominant.
The wild type trait is represented by gray bodies and red eyes while the mutant trait is represented by black body and/or cinnabar eyes. A cross between the wild type and the mutant only yield F1 offspring with wild type phenotype. This, thus, means that the wild type trait is dominant while the mutant trait is recessive.
Since the wild type trait is depicted by gray body and red eyes, it means that the gray body and red eyes traits are dominant while the black body and cinnabar eyes are recessive.
The correct option is d.

How are enzymes important for biochemical reactions?Enzymes are often called a catalyst because they increase can the speed of a biochemical reaction. Scientists often measure how quickly biochemical reactions occur in cells. The time it takes for a biochemical reaction to start and finish is known as the reaction rate.
Enzymes share two key characteristics with all other catalysts. First, they speed up chemical processes without being eaten or irreversibly changed by the process. They also speed up reactions while maintaining the chemical equilibrium between reactants and products.
Therefore, the enzyme acts as a catalyst to speed up a biochemical reaction.

1. How does the cell membrane allow animals to move without rupturing the cells in the body?
2. How does a cell membrane allow some molecules to pass right through the membrane?
3. Why is it important the some molecules (oxygen and carbon dioxide) be allowed to pass through the cell membrane without the use of a transport system?
4. How does the cell membrane allow the cell to reproduce into two separate cells?
5. In the lab, small bubbles would merge with the larger bubbles. How does this property of cell membranes demonstrate how a vesicle can transport substances from one organelle to another?
6. Cells require molecules that cannot simply pass through the cell membrane. Explain how the cell can use proteins to transport these molecules across the cell membrane.
.
Explanation:
1)The cell membrane functions as a semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell. Electron microscopic examinations of cell membranes have led to the development of the lipid bilayer model (also referred to as the fluid-mosaic model). The most common molecule in the model is the phospholipid, which has a polar (hydrophilic) head and two nonpolar (hydrophobic) tails.
2) simple diffusion across the cell plasma membrane. The structure of the lipid bilayer allows small, uncharged substances such as oxygen and carbon dioxide, and hydrophobic molecules such as lipids, to pass through the cell membrane, down the concentration gradient is , by simple diffusion.
3) some molecules, such as carbon dioxide and oxygen, can diffuse across the plasma membrane directly, but others need help to cross its hydrophobic or however, because they are charged the polar, they can't cross the phospholipid part of the membrane without help .
4) during fission a copy of the DNA is made and attached to the cell membrane as well. As this cell elongate in preparation for fission, the two DNA copies are pulled apart two opposite ends of the cell. New membrane material is deposited between the two ends of the cell, and a new wall grows between them .
