cause they can grow back again after they are used
Answer:
Trees
Explanation:
Coal and oil are both fossil fuels, which are dug up from the Earth and burned for energy. Once those are used up, we can't get more of it because they take millions of years to form. Plastic is made from fossil fuels, so that doesn't work either.
Trees are a renewable resource because trees can be continuously, sustainably grown and will never run out.

who created the earth
Answers
Explanation:
Hey, there!
It's not obvious that who created the Earth.
Noone can say the answer of who created Earth because Earth wasn't created by any human or any specific creatures.. So, let me give some information about creation of Earth. Many hypothesis has been given by our great astronomers and philosophers. Here, i'm gonna describe some:
Old planetesimal hypothesis: According to this hypothesis there was a huge gaseous mass and comet collided together as a result, a very large amount of matter was thrown out of the sun, which later on cooled and planets are formed.Nebular hypothesis: According to this hypothesis the sun, the earth and other planets were formed by a large whirling cloud of hot gases and dust. When the cloud cooled and grew smaller, it began to spin faster. As the surface of the cloud cooled by radiation, a ring a matter was formed at the equatorial region of it.New plantesimal hypothesis: According to this hypothesis, the gaseous mass didn't collied with comet but they came closer to one another and due to gravity of comet, great tidal rose on gaseous mass. The materials rise up as a large spiral arms. Then the spiral arms were cooled down and broke away from the main mass. Then they were considered to be planets and main mass as the sun. It is modern of old plantesimal hypothesis. Tidal hypothesis: According to this hypothesis, it was also supposed that a comet passed through and had exerted a tidal pull upon a mass. The outer part of the filament escaped into space, inner part came back into the gaseous mass and middle part formed different sizes, which were planets and remaining were sun.Dust-cloud hypothesis: This hypothesis is different tgan above. It says tgat all planets were formed by large cloud of dust and gases. The light of stars pushed the atoms of gases and dust to form a large particals. These particals were attracted to eachother by gravity and began to crowd together. Eventually, a huge ball of materials formed the sun and the solar enegry was produced by nuclear reaction. Other particals remain near the sun and started revolving around it. The huge whirlpools originated in the rotating clouds which formed the smaller gaseous glodsand dust to form planets.This is how the earth was originated or created according to different hypothesis. so, there is no any single people or things that created the earth.

Which mechanism decreases the number of genatic varitaions in a population
Answers
One mechanism that can decrease the number of genetic variations in a population is natural selection.
Natural selection is a process by which certain traits become more or less common in a population based on how well they enable individuals to survive and reproduce in a given environment. Traits that increase an individual's likelihood of survival and reproduction will tend to become more common over time, while traits that decrease an individual's fitness will tend to become less common.
As natural selection acts on a population, it can reduce the number of genetic variations by selecting for certain traits and eliminating others. Over time, this can lead to a reduction in the genetic diversity of a population, as certain traits become more and more common and others are lost.

Gas pockets from volatiles in the lava c. Slivers of volcanic glass from the lava d. Rock fragments that erupted from the volcano
Answers
Welded tuff consists of ash surrounding large, jagged, irregularly-shaped pieces of material. It is silver of volcanic glass that come from lava. The correct answer is option c.
Welded tuff is a type of rock that is formed from the consolidation of volcanic ash and other material. The material in welded tuff that consists of large, jagged, irregularly-shaped pieces is crucial to understanding the formation and properties of the rock.
The material in question is actually slivers of volcanic glass that were formed from the rapid cooling of molten lava. When lava erupts from a volcano and comes into contact with air or water, it cools rapidly and forms a glassy, amorphous material known as volcanic glass. This glassy material is fragmented into small pieces as a result of the explosive force of the eruption.
The fragments of volcanic glass are then incorporated into the surrounding ash to form welded tuff. As the ash and glass fragments settle and compact, they bond together, resulting in a rock that is characteristically dense and hard. The jagged, irregular shape of the glass fragments gives welded tuff its distinctive appearance and makes it an important type of rock for geologists to study.

Part B)
Calculate the number of molecules on the surface of the water.
Part C)
How many molecules per mole would there be?
I need solution of all parts A, B and C
Answers
A solution is a homogeneous mixture of two or more substances, where one substance (called the solute) is dissolved in another substance (called the solvent).
Part A:
To calculate the area of a molecule assuming it has a cubic shape, where a side of the cube represents the height of the monolayer, we can use the formula:
Area of a molecule = (Side length of the cube)^2
If we denote the side length of the cube as "s," then the area of a molecule can be calculated as:
Area of a molecule = s^2
Part B:
To calculate the number of molecules on the surface of the water, we need to know the surface area available for the molecules and the area occupied by each molecule.
Let's assume that the total surface area available for the molecules is denoted as "A" (in square units) and the area of a single molecule is denoted as "M" (in square units).
The number of molecules on the surface of the water can be calculated using the formula:
Number of molecules = (Total surface area)/(Area of a single molecule)
Number of molecules = A/M
Part C:
The number of molecules per mole can be calculated using Avogadro's number (6.022 x 10^23 molecules/mol).
If we know the number of molecules, we can calculate the number of moles using the formula:
Number of moles = (Number of molecules)/(Avogadro's number)
Number of moles = (Number of molecules)/(6.022 x 10^23)

the pox virion shown lacks click to view larger image. group of answer choices a genome. an envelope. spike proteins. an icosahedral capsid.
Answers
The pox virion displayed in the image lacks an envelope, which differentiates it from other enveloped viruses. It possesses an icosahedral capsid, a core containing the genome, and lateral bodies, which are important for the virus's infection and replication processes.
The correct answer is an envelope.
The capsid is composed of protein subunits that form an icosahedral shape, which provides protection and stability to the viral genome. The core houses the viral DNA and essential enzymes required for replication and transcription.
However, unlike many other viruses, poxviruses do not have an envelope surrounding their capsid. An envelope is a lipid bilayer derived from the host cell membrane, often containing viral spike proteins. These proteins play a crucial role in binding and entry into host cells.
Despite lacking an envelope, poxviruses can still efficiently infect host cells by utilizing specialized structures and proteins on their capsid surface.
Therefore the correct answer is an envelope.

Answers
The probability that the differences you observe in progeny numbers is due to chance can be calculated using a Chi-Squared Test.
In this case, the expected ratio of 1:1 for the yellow and green seeds would mean you'd expect 56 progeny for each.
The observed numbers of 58 and 54 are slightly different than the expected numbers, so you can use the Chi-Squared Test to calculate the probability that this difference is due to chance. The closest value from Table 3.7 in this case is 0.042.
If the calculated value is greater than the critical value, then the differences are significant and not due to chance.

Which of the following correctly describes the relationship between an enzyme and its function? A. adenylyl cyclase: conversion of CAMP to AMP
B. phosphatase: removal of a phosphate group
C. glycogen phosphorylase: synthesis of glycogen
D. kinase: addition of a tyrosine
Answers
The correct description of the relationship between an enzyme and its function is option B, phosphatase: removal of a phosphate group.
Enzymes are biological catalysts that facilitate chemical reactions in living organisms. Each enzyme has a specific function based on its structure and the reaction it catalyzes. Option B correctly describes the relationship between the enzyme and its function. A phosphatase is an enzyme that removes a phosphate group from a molecule. Phosphatases play a crucial role in cellular signaling and metabolic pathways by regulating the addition and removal of phosphate groups. The removal of a phosphate group by a phosphatase enzyme can have significant effects on the activity and function of the target molecule, such as protein deactivation or modulation of enzyme activity. In contrast, options A, C, and D do not accurately represent the relationship between the enzyme and its function. Option A describes adenylyl cyclase as converting CAMP to AMP, which is incorrect. Option C suggests glycogen phosphorylase is involved in glycogen synthesis, while it is actually responsible for glycogen breakdown. Option D associates kinase with the addition of a tyrosine, whereas kinases are generally involved in the transfer of phosphate groups, not specific to tyrosine.

The location that would probably have the greatest average intensity of insolation per unit area over a period of one year would be (1) Tropic of Cancer, 23.5° N.
What is the area?The amount of solar radiation that strikes a specific region is known as insolation, and it is influenced by things like the angle of incidence, the duration of the day, and meteorological conditions. At 23.5° N, the Tropic of Cancer is near to the equator and receives more direct sunshine all year round.

which type(s) of epithelial cells have a basal lamina?
Answers
Epithelial cells, categorized by shape and arrangement, possess a basal lamina—a thin extracellular matrix layer—underneath. It provides support, structure, barrier functions, and aids in cell signaling for different types of epithelial cells.
All types of epithelial cells have a basal lamina, which is a thin layer of extracellular matrix that lies underneath the epithelium. The basal lamina serves as a foundation for epithelial cells and helps to maintain their structure, while also functioning as a barrier and playing a role in cell signaling.
Epithelial cells are classified into different types based on their shape and arrangement. The three main shapes are squamous (flat), cuboidal (cube-shaped), and columnar (tall and narrow). These cells can be arranged in a single layer (simple epithelium) or multiple layers (stratified epithelium). Additionally, there are transitional epithelial cells, which can change their shape in response to physical stress or pressure.
Each type of epithelial cell, whether squamous, cuboidal, columnar, or transitional, has a basal lamina. This layer provides essential support for the cells and enables them to carry out their functions effectively, which can include protection, secretion, absorption, and transportation of substances across the epithelial barrier.
The composition of the basal lamina can vary depending on the specific type of epithelium and its location in the body. However, it typically consists of proteins such as collagen, laminin, and fibronectin, as well as glycoproteins and proteoglycans. These components interact to form a stable, yet flexible, structure that enables epithelial cells to maintain their integrity and perform their roles in various tissues and organs throughout the body.
