HOPE THIS HELPS!
I need help please!!
Answer:
Prokaryotes and Eukaryotes are two types of cells with similarities and differences. Eukaryotes are plant cells and animal cells. They are mostly found in multi-cellular organisms. Prokaryotes are usually single-celled organisms and have a tail. Those are the examples that I remember, but there are way more similarities and differences. I hope this helped!!
Without leaves green plants could not
Answer:Without leaves green plants could not live.
Explanation:because from leaves a plant take breath or do respiration. In leaves of plants there are small pores or stomata from where they breathe. So if we can't breathe we can't live.so,Without leaves green plants could not live.

(select only one answer)
natural selection
Answer:
The correct answer is-
4. true
5. Natural selection
6. microevolution
Explanation:
Adaptive radiation is a cycle where living beings diversifying rapidly from a familial or an ancestral species into a huge number of several new types, especially when there are new environmental aspects present such as different habitats and few competitors.
Thus, it is a true statement.
Natural selection is the cycle through which a population or a species of living beings adjust and change over the period of time. natural selection just acts upon the heritable attributes of a population by choosing for advantageous alleles or and in this manner increasing the frequency of these adaptive alleles in the population.
Thus the option Natural selection is correct.
Changes inside a genetic pool from happening to one generation to another is known as microevolution. Allele frequencies in a population may change because of, natural selection, mutation, genetic drift, and genetic flow.
Thus, the correct answer is - microevolution.

Explanation:
All fish nitrogen into the water as ammonia and organic nitrogen. These chemicals are byproducts of their metabolism and respiration.
Answer:
The correct answer would be - release/excretes.
Explanation:
In ponds, rivers, or similar ecosystem nitrogen cycle is completed with the help of the fishes. In this ecosystem, the nitrogen cycle initiates with the eating plants or fish food by the fishes and performs metabolism and cellular respiration which produces byproduct ammonia and organic nitrogen as animal waste.
This waste is released or excreted by the fish in the water where the beneficial bacterium helps in restoring nitrogen back to the atmosphere by breaking these wastes.
How many bacteria will there be after four hours from a single bacterium that divides to produce two cells every 15 minutes
Answer:
65,536 cells
Explanation:
According to the question, a single bacterium will divide into new cells every 15minutes. Since there are four 15 minutes in one hour, which is 60 minutes, a single bacterium will have divided (4×60/15) times =
= 240/15
= 16 times.
Since a single bacterium will divide 16 times in four hours cells, then in four hours, a single bacterium will have divided into 2^16 = 65536 new cells.
Note that, the number of cells a bacterium cell that will divide in two can be expressed as 2^n where n is the number of times
If a bacterium divides into 2 every 15 minutes, there would be 65536 bacteria after four hours.
The bacterium divides into 2 every 15 minutes. Thus, the cell will divide:
60/15 x 4 = 16 times in 4 hours
Thus:
First division = 2 cellsSecond division = 4 cellsThird division = 8 cellsFourth = 16 cellsFifth = 32 cellsSixth = 64Seventh = 128Eighth = 256Ninth = 512Tenth = 1024Eleventh = 2048Twelfth = 4096Thirteenth = 8192Fourteenth = 16384Fifteenth = 32768Sixteenth = 65536More on bacterial division can be found here: https://brainly.com/question/621474

Polar molecules have ends or poles that are partially charged. The opposite ends of a polar molecule will
have____.
A. the same type of charges
B. opposite charges
Answer:
B. opposite charges
Explanation:
Polarity is a separation of electric charge leading to a molecule or its chemical groups having an electric dipole moment, with a negatively charged end and a positively charged end.
Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms.

For something to be considered living, it must be composed of at least one what?
Answer:
[tex]\boxed {\tt Cell}[/tex]
Explanation:
There are many characteristics of life, including, cells. A cell is a tiny unit of life that carries out many different processes.
If something is considered living, it must have at least one cell, but it can have more. For example, bacteria is unicellular and living. We (humans) are also living, but made of billions of cells.
Therefore, for something to be considered living, it must be composed of at least one cell.

Explanation:
Certain unusual aspects of brain structure were observed in the brain of Albert Einstein. One interpretation is that he was born with certain differences in his cortex from others that encouraged his scientific and intellectual abilities. What do you think of this explanation and what do you think could be an alternative interpretation
Answer:
It seems a plausible inference. An alternative hypothesis is one in which this anatomical difference is present in low population frequency, thereby further scientific observations are needed to confirm (or reject) this hypothesis
Explanation:
Albert Einstein's brain exhibited an unusual anatomical conformation in the prefrontal cortex. Intriguingly, this brain area is involved in abstract thinking, thereby it has been suggested that the amazing cognitive capacities of Einstein may be due to his prefrontal cortex. A way to test this hypothesis is by an observational study with the aim at determining if this feature is exclusive of Einstein's brain.
