Why have plants been implicated in the devonian glaciations and not in the proterozoic glaciations?
The reason why plants have been implicated in the devonian glaciations and not in the proterozoic glaciations is; Land plants had not yet evolved during the Proterozoic.
Why have plants been dying?The Devonian glaciation occurred in south America and caused a global narrowing of the warm climatic belts, sharp regression, increased clastic sedimentation.
Meanwhile, the Proterozoic glaciation occurred near sea level in low palaeolatitudes. Thus, we can say that the reasons why plants have been implicated in the devonian glaciations and not in the proterozoic glaciations is because land plants had not yet evolved during the Proterozoic.

Saturn is close to Polaris during some years
true or false
Saturn is not close to polaris
Polaris disappears into the horizon as seen from the equator, and is not visible from the south of the equator. Finding Polaris in the Northern Hemisphere indicates that you are aware of the direction north.
What is the importance of Polaris?Directly above Earth's North Pole is the Pole Star, or Polaris. Due to its location over the North Pole, the pole star is aligned with the earth's axis. As the sole star that is stationary, it is crucial for orientation.
It makes a fairly small circle over the course of a day since it is so close to the celestial equator. As a result, Polaris is a trustworthy indicator of north, since it always remains in nearly the same location in the sky.
Therefore, it is false that Saturn is close to Polaris during some years.

Worldwide, what percentage of human water usage is the result of agricultural activity? What are some of the ways water is used in industry?
Answer:
70% fresh water is used for agriculture According to the United States Geological Survey (USGS), industrial water is used for fabricating, processing, washing, diluting, cooling, or transporting a product. Water is also used by smelting facilities, petroleum refineries, and industries producing chemical products, food, and paper products.
Answer:
In most regions of the world, over 70 percent of freshwater is used for agriculture. By 2050, feeding a planet of 9 billion people will require an estimated 50 percent increase in agricultural production and a 15 percent increase in water withdrawals.
Explanation:
Water is a critical input for agricultural production and plays an important role in food security. Irrigated agriculture represents 20 percent of the total cultivated land and contributes 40 percent of the total food produced worldwide.

A microbiologist has a bacterial culture with 100,000 cells per mL of nutrient broth, but needs to dilute the culture with sterile nutrient broth to 1,000 cells/mL. To accomplish this, the microbiologist should dilute 1 mL of the culture to what total volume, in mL?
A. 10
B. 90
C. 100
D. 1, 000
PLEASE EXPLAIN ASAP
To accomplish the dilution the microbiologist should dilute 1 mL of the bacterial culture in 100 mL of the total volume. Thus, option C is correct.
What is dilution?Dilution is a process of decreasing the solute concentration by the addition of the solvent in the solution. The volume for the dilution is calculated as:
Given,
C1 = 100,000 cell per mL
C2 = 1000 cell per mL
V1 = 1 mL
C1 V1 = C2 V2
100,000 × (1 ÷ 1000)
= 100 mL
Therefore, 100 mL should be used to dilute 1 mL.

Explain why the biodegradation of plastic might be more hazardous to the environment than the presence of plastic as marine debris.
Answer:
they generate a large amount of macrobiotic flora which can cause diseases to humans as well as animals
Answer:
While plastic is not generally considered biodegradable, it can be broken down by the action of photodegradation and certain microbes. The breakdown products of plastic, however, are extremely toxic to marine life and once the plastic breaks down they are free to enter into the food chain. Therefore, while plastic marine debris is hazardous and dangerous to marine organisms, the toxic breakdown products of plastics have the potential to do even more damage.

The DNA sequences for Species A is CTGTCCGAAG and Species B is CTGTCCGTCG. How many years ago did these species diverge from a common ancestor? 660,000 years ago
33 years ago
330,000 years ago
6,000 years ago
The homo-logous mitochondrial sequences CTGTCCGAAG and CTGTCCGTCG suggest that species diverge from a common ancestor 660,000 years ago.
What is the mutation rate?The mutation rate indicates the number of nucleotide differences between two homo-logous sequences that emerged in evolution in a given period of time.
In this case, the mutation rate is one nucleotide per 330,000 years and here we have two mutations (CTGTCCGAAG and CTGTCCGTCG), thereby it is expected that the sequences diverged 660,000 years ago.
In conclusion, the homo-logous mitochondrial sequences CTGTCCGAAG and CTGTCCGTCG suggest that species diverge from a common ancestor 660,000 years ago.

Answer: A
Explanation:
Lobes were the beginning of arms and legs, the correct option is A.
What are lobe-finned fish?Lobe-finned fish, unlike other fish, have a core protuberance in their fins that contains many bones and muscles.
The fins are extremely flexible and may be useful for supporting the body on land, as seen in lungfish and tetrapods.
The majority of bony fish have ray fins. These thin fins are made up of skin webs that cover flexible spines. Lobe-finned fish, on the other hand, have fins that look like stumps.
The lobe-finned fishes are the ray-finned fishes' sister group. They are distinguished by paired, fleshy pectoral and pelvic fins espoused by a single bone.
Prehistoric records clearly show that terrestrial vertebrates evolved nearly 400 million years ago from lobe-finned fishes.
Thus, the correct option is A.
