Ripple marks are ridges of sediment that form in response to wind blowing along a layer of sediment. ... The symmetry of water-current ripple marks indicate whether they were formed by gentle waves or faster water currents.Answer:
Ripple Marks Ripple marks are sedimentary structures and indicate agitation by water (current or waves) or wind. Ripple marks are ridges of sediment that form in response to wind blowing along a layer of sediment. They are form perpendicular to the wind direction and each ridge is roughly equidistant from the ripple mark on either side.

List and describe the functions of at least six different types of tissue.
Answer:
Epithelial tissue, also referred to as epithelium, refers to the sheets of cells that cover exterior surfaces of the body, lines internal cavities and passageways, and forms certain glands. 2.Connective tissue, as its name implies, binds the cells and organs of the body together and functions in the protection, support, and integration of all parts of the body. 3. Muscle tissue is excitable, responding to stimulation and contracting to provide movement, and occurs as three major types: skeletal (voluntary) muscle, smooth muscle, and cardiac muscle in the heart. 4.Nervous tissue is also excitable, allowing the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body.5. Muscle tissue, which responds to stimulation and contracts to provide movement.6. Loose connective tissue. Loose connective tissue is also called the areolar connective tissue. It has almost equal amounts of cells, fibers and ground substance.

What is the ultimate source of energy for all living things? A. Food B. The sun C. Water D. Oxygen
Answer:
B, The sun.
Explanation:
The Sun is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

An E. coli cell contains about 15,000 ribosomes, which carry out protein synthesis. Assuming ribosomes are spherical and have a diameter of 20.0 nm, calculate the fraction of the E. coli cell volume that is occupied by ribosomes.
Answer:
14.57%
Explanation:
From the previous lesson, we understood that the Volume of E.coli = 4.13 × 10⁻¹⁹ m³
The diameter of the ribosome = 20 nm
Radius will be D/2 = 20 nm/2 = 10 nm
The volume of the sphere since the shape of the ribosome is spherical = 4πr³
∴
The volume for each ribosome = 4πr³
For 15000 ribosome, we have:
[tex]= 15000 \times (\dfrac{4}{3}\pi) ((10^{-8})^3)[/tex]
[tex]= 15000 \times (\dfrac{4}{3}\pi) (10^{-24})[/tex]
= 6.283 × 10⁻²⁰
Thus, the fraction of E.coli volume occupied by the ribosome can be determined by using the formula:
[tex]= \dfrac{Vol. \ of \ ribosome}{Vol. \ of \ E.coli}\times 100[/tex]
[tex]= \dfrac{6.283 \times 10^{-20}}{4.31 \times 10^{-19}}\times 100[/tex]
= 14.57%
What is natural selection?
Answer:
Basically in simple terms, a process in which capable animals can adapt and live longer to their environment than to others. Like a light colored mice on dark rock wouldn't survive unlike dark colored mice
Explanation:
In nature, living organisms have to navigate conditions (such as severe heat, extreme cold, drought, predation, food scarcity, etc) surrounding their existence in order to survive.
The theory of evolution states that as they conquer these conditions, their behavior and physical abilities, and traits evolve and become efficient at doing so.
These traits are then passed on to their offspring via the process of reproduction.
The process by which their physical qualities change to survive their environment is called adaptation.
Those who are unable to evolve are terminated by the harsh conditions of nature. Those who are unable to pass their abilities to survive to their offspring also get wiped off. Those who adapt and reproduce are deemed to be selected naturally to survive hence the term - Natural Selection.
Hence natural selection is a component of evolution.
Evolutionists have stated that the Giraffe is an example of an animal that evolved. It developed a long neck to enable it to reach for food far off the ground and on trees when there was a condition that wiped off shrubs available for them to graze on easily off the ground.
As giraffes with longer necks grazed and fed well, they passed on the gene to their offspring whilst those without adequately long necks got terminated by nature.
Another example is given in the attached picture. The animal in the picture is a desert dragon lizard adapting the color of its skin to blend to its environment in order to escape being spotted by desert hawks that prey on them.

g Knowing if a bacterium is Gram-positive or Gram-negative is important in medicine because it tells us what type of antibiotic will be used (e.g., penicillin for Gram-positive bacteria and mycins, like streptomycin, for Gram-negative bacteria). Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. a True b False
Answer:
This is true.
Explanation:
Knowing whether a bacteria is gram positive or negative will help to narrow down the types of pathogen it could be and will determine which antibiotics will be effective against it.
Knowing whether a bacteria is gram positive or gram negative will help to understand the kind of infection it may cause and thus help in determining the kind of antibiotic it needs.
What are gram-positive and gram-negative bacteria?The bacteria that have a thick layer of peptidoglycan but no outer lipid membrane are called Gram-positive bacteria. The bacteria that have a thin layer of peptidoglycan and an outer lipid membrane are called gram-negative bacteria.
Gram-positive bacteria do not have an outer lipid membrane and hence they retain the crystal violet in the thick peptidoglycan during gram staining and it is fixed by iodine.
The outer lipid membrane that is possessed by the Gram-negative bacteria does not allow them to retain the crystal violet and hence only the counterstain safranin is visible in the gram staining method.
The technique of Gram staining was developed by the bacteriologist Hans Christian Gram in 1884. While this method cannot tell the specific strain of a bacteria, it can be used as a quick and easy way for narrowing down the basic criteria of distinguishing the bacteria among the two main groups.
Therefore, knowing whether a bacteria is gram positive or gram negative will help to understand the kind of infection it may cause and thus help in determining the kind of antibiotic it needs.

Rickettsia typhi is a species of infectious bacterium that is an obligatory intracellular parasite. This means that, similar to viruses, R. typhi cannot reproduce and survive outside of a eukaryotic cell. Why do we consider viruses nonliving, but rickettsia alive
Answer:
Due to its characteristics.
Explanation:
We consider viruses are nonliving, but rickettsia are living because rickettsia have the characteristics of bacteria which is a living and has unique structure. It also survives outside the living cell but not for long time. The rickettsia remain in their shape and does not form crystalline structure like viruses outside the cell. If there is suitable environment for rickettsia, it can survive in that environment.
