the evidence that all life on Earth shares common features is that All life on Earth performs transcription and translation in a similar fashion. and All life on Earth has cells surrounded by membranes.

What is transcription and translation?

The process of transcribing a piece of DNA into RNA is known as transcription. Messenger RNA is created when segments of DNA are translated into RNA molecules that can encode proteins. Translation is the process by which ribosomes in the cytoplasm or endoplasmic reticulum create proteins following the transcription of DNA to RNA in the cell's nucleus. The entire process is known as gene expression.

What is cell membrane?

The cell membrane, also known as the plasma membrane, is found in all cells and serves to separate the cell's interior from the outside environment. The cell membrane is made up of a semipermeable lipid bilayer. The cell membrane controls the transport of materials into and out of the cell.

The organisms that feed on dead and decaying matter are called Saprotrophs.

An organism that feeds on dead and decaying organic matter is called a saprotroph. These organisms are heterotrophic, which means that they obtain their food from other sources. They are important in the ecosystem because they break down dead organic matter and recycle it back into the soil, making nutrients available to other living organisms

Answer:

A. Saprotrophs

Explanation:

Saprotrophs are organisms that obtain their nutrients by feeding on dead and decaying matter. They play a crucial role in the ecosystem by decomposing organic material and recycling nutrients back into the environment.

These organisms secrete enzymes that break down complex organic compounds into simpler substances, such as sugars and amino acids, which they can absorb and utilize for their own growth and energy needs. Examples of saprotrophs include fungi (such as mushrooms and molds) and certain bacteria.

Unlike autotrophs, which can produce their own food through photosynthesis or chemosynthesis, saprotrophs rely on external sources of organic matter for their nutrition. They actively decompose dead plants, animals, and other organic materials, aiding in the process of nutrient recycling and decomposition.

Heterotrophs, on the other hand, are a broader category of organisms that obtain their nutrients by consuming other living or dead organisms. This includes saprotrophs, as well as other types of organisms such as herbivores, carnivores, and omnivores.

Parasites, meanwhile, are organisms that live in or on other organisms, known as hosts, and obtain their nutrients from the host while causing harm or damage to it. Unlike saprotrophs, parasites typically rely on a living host for their sustenance rather than feeding on dead and decaying matter.

Mobile receptors play a crucial role in the transmission of signals between cells and are essential for various physiological processes in the human body. These receptors are proteins that are embedded in the cell membrane and are specifically designed to bind with specific molecules, such as hormones, neurotransmitters, and other signaling molecules. The mechanism of mobile receptors involves several steps that allow for the efficient and accurate transmission of signals.

1: Binding: The mobile receptor recognizes and binds to its specific ligand, which is the signaling molecule. This binding occurs through complementary shapes and chemical interactions between the receptor and the ligand.

2: Activation: Once the ligand binds to the mobile receptor, it induces a conformational change in the receptor's structure. This change activates the receptor and initiates a series of intracellular events.

3: Signal Transduction: The activated receptor transmits the signal across the cell membrane. It can either directly activate intracellular signaling molecules or interact with other proteins to relay the signal.

4: Cellular Response: The signal transmitted by the mobile receptor triggers a cascade of intracellular events that ultimately leads to a specific cellular response. This response can include changes in gene expression, enzyme activity, ion channel opening, or cell signaling pathways.

5: Termination: To ensure proper regulation, the mobile receptor signal is terminated once the ligand dissociates from the receptor. This allows the receptor to return to its inactive state and be available for future signaling events.

Overall, the mechanism of mobile receptors involves ligand binding, receptor activation, signal transduction, cellular response, and termination of the signal. This intricate process enables cells to communicate and coordinate their functions, contributing to the overall homeostasis and functioning of the human body.

Carbon

Explanation:

Human activities are known to substantially alter the carbon cycle. New strategies applied to land-use systems, burning fossil fuels, and the use of limestone as building material are activities that emit high amounts of carbon into the atmosphere. It is well known that the excess of carbon as carbon dioxide (CO2) into the atmosphere warms the planet because this gas is an important heat-trapping (greenhouse) gas. Moreover, it is also important to note that deforestation also affects the carbon cycle since plants use CO2 during photosynthesis.

reprotuctive answer because it is animal cells

In most of the animals, the digested food is transported to all the cells of the body by the circulatory system. The circulatory system is responsible for the conduction of different materials with the blood.

The walls of the small intestine absorb the digested nutrients from the food into the bloodstream. The blood delivers all the nutrients to the rest of the body parts. The blood in the blood vessels transports it other parts of the body.

The digested food molecules and nutrients are transported to other parts of the body which then either store the nutrients or further change it chemically into other molecules. Specialized cells are present in the walls of intestine which help absorbed materials to cross the intestinal lining into the bloodstream.

In most animals, blood that circulates in the body distributes nutrients and gases to different cells of the body. It also takes waste products from different parts of the body for excretion.

Answer:

Biofuels are renewable fuels that are produced from biomass, organisms that were formed and stopped living a short time ago. The energy in the biofuels is called bioenergy. The major constituents of biomass are cellulose, lignin, starch and sugar, but many plants also contain other organic compounds that are beneficial for energy recovery from the material due to their physical structure and chemical composition. The difference between biofuels and fossil fuels is that fossil fuels take millions of years for new formation while new biomass for biofuels is constantly being formed. This means that biofuels can usually be considered carbon neutral as the carbon dioxide emitted during combustion is constantly bound to new biomass in a closed cycle.

Answer:

1. R is dominant, and r is recessive. I know this information because the crossing of two pure red and white tulips means that the red tulip genotype is RR,  and the white is rr. In other words, they are two h0m0zygous alleles. When we do a Punnet square, we can see that all the progeny is red since it is the trait that dominated over the white one.

a. R represents the red petal color.

b. r represents the white petal color.

Explanation:

To determine which gene is the dominant and which one is the recessive, we have to look at the information that we have.

We know that the cross of a pure red tulip and a pure white tulip results in all red tulips. If we know that they are pure, they are hom0zygonious (RR and rr).

When we draw a Punnet square we can see that the offsprings will all have the genotype Rr and as we knew that offsprings were all red, we can deduce that the domiant trait is red (R), while the recessive one (white) is r. In other words, the dominat gene (red) will express itself while the recessive(white) won't. As a result, the tulips will be red.
