If plants were removed from the carbon cycle, carbon will accumulate in the air as carbon dioxide and animals will not be able to obtain carbon.
What is the carbon cycle?The carbon cycle is a cycle that describes how carbon is recycled between the living and the non-living component of the environment.
Carbon is an essential element both for the living and the non-living components of the environment.
In living organisms, carbon is known as the element of life. This is because all living organisms require carbon for their existence. Carbon forms the backbone of all organic molecules.
Thus, in the carbon cycle, carbon is cycled between plants and animals, the atmosphere as well as in ocean water. Plants remove carbon from the atmosphere during photosynthesis. Animals release carbon during respiration.

which of the following is true of neandertals? select one: a. they could control fire. b. they deliberately buried their dead. c. they are considered by many archaeologists to be a subgroup of homo sapiens. d. all of the answers are correct.
Neanderthals performed funeral ceremonies and buried their deceased using flowers.
In 1908, a possible Neanderthal tomb was first found in southwest France at La Chapelle-aux-Saints. These 50,000-year-old bones' excellent preservation prompted scientists to hypothesize that Neanderthals interred their dead long before modern humans reached western Europe. At the time, soil samples connected to one of the bones included clusters of flower pollen, which led researchers to hypothesize that Neanderthals performed burial ceremonies and buried their dead using flowers. To bury their dead, Homo neanderthalensis (Neanderthals) built pits. They buried their deceased using flowers in their funeral ceremonies .The purposeful placement of remains in caverns and their intentional burial date to around 115,000 years ago at Qazfeh in Israel.

What is gravitation lensing and how does it cause arcs of light around galaxies
Gravitational lens can occur when a huge amount of matter, like a cluster of galaxies, creates a gravitational field that distorts the light from distant galaxies.
Gravitational lensing is a powerful tool that affects the clustering components in the universe by effecting gravitational field on light from background sources.
When the light from other galaxies passes by massive objects in the universe, the gravitational pull from these objects can distort or bend the light. The gravity of the massive focal point were galaxy is acting like a magnifying glass as it traps light and this effect called gravitational lensing.

Explanation:
two different bacterial species with doubling times of 2 h and 4 h are growing in a batch nutrient-rich medium with their maximum growth rate. the initial concentrations are the same. a. what would be the ratio of x1/x2 after 10 h of batch growth? b. how long should the batch growth of the mixed cultures last in order to obtain x1/x2
The ratio of x1/x2 after 10 h of batch growth would be 2:1. The batch growth of the mixed cultures should last for 20 h in order to obtain x1/x2.
We calculate this using,
a) Rate
N= N0ekt
For each bacteria we have to find out K so first bacteria with doubling time 2 hour
Assume there were 100 bacterias then after 2 hours there will be 200 bacterias
so N = 200 , N0=100 and t=2 hours
200 = 100*ek*2
200/100 = e^2K
e^2K = 2
Taking ln on both sides
2K = ln 2
K = ln2/2
=0.34657
The equation for bacteria X1
N0= Ne0.346t
For bacteria X2 K= ln2/4 ( because only difference here is the doubling time) =0.17328
So the equation for X2
N0= Ne0.173t
a) X1/X2 after 10 hours so t = 10
Ne0.346t / Ne
0.173t=e0.346t / e0.173t
= e0.346*10 / e0.173*10
= 31.817 / 5.64
=5.6413
b) X1 / X2= 10
e0.346t / e0.173t =10
Taking ln on both sides
ln ( e0.346t / e0.173t )= ln 10
ln e0.346t- ln e0.173t = ln 10
0.346t- 0.173t = 2.302
t ( 0.346- 0.173 ) = 2.302
t = 2.302/ ( 0.346 - 0.173)
=13.306
So the time is 13.306 hours

To investigate how the vegetation in a coastal ecosystem changes with distance from

(A) a line transect placed across the ecosystem
(B) regular observation of the ecosystem
(C) a quadrat placed randomly within the ecosystem
(D) a piece of string placed across the ecosystem
which gives results obtained
A line transect placed across the ecosystem is the best sampling technique.
What kind of vegetation is there along the coast?
Maritime forests, scrub thickets, grassy upland grasslands, freshwater swamps, freshwater marshes, mangrove swamps, saltwater marshes, and grassy or forested dunes are a few examples of common coastal vegetation environments.
What is line transect method?
As a guide for a sampling technique used to determine the distribution of organisms, a tape or string is laid along the ground in a straight line between two poles. Sampling is strictly limited to organisms that are in direct contact with the line.Another form of systematic sampling, similar to the belt transect, is the line transect. The line transect involves drawing a line through a habitat. It might be as easy as laying a string or rope across a habitat. In this strategy, the organisms that really touch the line are taken into account. As a result, only organisms that come into contact with the line can be sampled.Despite being similar to the belt transect, this approach only yields a little amount of data. It merely displays the changes occurring along the line. Species' existence and absence are noted. It displays a specific linear or gradient pattern along the line. With the aid of scale-drawn icons for various species, the data is presented as a diagram. The relative densities of different species cannot be determined via a line transect. The belt transect method is slower than this one, though.Hence line transect method is best used to investigate the vegetation of coastal system.

Two nucleotides on the same strand form a Phosphodiester bond while two complimentary bases on opposite strands form Hydrogen bonds. An a-t base pairing forms 2 such bonds.
The constituent components that make up DNA's double-helix structure are known as nucleotides. Each nucleotide has a base in it. The four various colors you see here stand for the four different bases that might be used. Between nucleotides, a unique kind of covalent link known as a phosphodiester bond occurs. The two strands of DNA are formed by these phosphodiester linkages.
Hydrogen bonds are the bonds that develop between base pairs. Thymine and adenine make two hydrogen bonds, and guanine and cytosine form three hydrogen bonds. Therefore, we have concluded that hydrogen bonds are the type of binding that develops between base pairs in DNA to hold the two strands of a double helix together.
