Plants take in useful nitrogen compounds from the soil.
The first step in the nitrogen cycle is: Soil bacteria act to "fix" atmospheric nitrogen to form ammonia. Plants take in useful nitrogen compounds from the soil ; option C
What is the nitrogen cycle?The nitrogen cycle refers to the processes by which nitrogen is cycled between the living and non-living components of the environment.
The nitrogen cycle is important as it helps provide plants with the useful nitrogen which they require for growth.
There are seven steps in the nitrogen cycle and they are:
nitrogen fixation,assimilation,ammonification,nitrification,denitrification,dissimilatory nitrate reduction to ammonia,anaerobic ammonia oxidationThe first step in the nitrogen cycle is nitrogen fixation which is the process by which atmospheric nitrogen is fixed into the soil by soil bacteria in a useful form required by plants. Therefore, step C occurs first.
In conclusion, the nitrogen cycle is important for plant growth.

Which phrase describes an irregular galaxy?
has a round shape
contains many young stars
has arms that extend from the center
is larger than other types of galaxies
Answer:
"Contains many young stars".
Explanation:
The phrase that describes an irregular galaxy is "contains many young stars". The correct option is B.
What is a galaxy?A galaxy is a collection of stars, stellar remains, interstellar gas, dust, and dark matter that are gravitationally bonded together.
A galaxy is a vast collection of stars, solar systems, gas, and dust. Gravity holds a galaxy together. A supermassive black hole also resides in the centre of our galaxy, the Milky Way.
In contrast to spiral or elliptical galaxies, irregular galaxies lack a recognizable regular shape.
Regular Hubble sequence classes do not apply to irregular galaxies, which typically have a chaotic appearance, no nuclear bulge, and no sign of spiral arm structure.
Thus, the correct option is B.

What is the major difference between rays and skates?
a) rays are endothermic, while skates are ectothermic
b) rays lay eggs, while skates give birth to live offspring
c) rays give birth to live offspring, while skates lay eggs
d) rays have flattened bodies, while skates do not
Answer:
c) rays give birth to live offspring, while skates lay eggs
Explanation:
Rays and skates are two species of cartilaginous fishes found in deep regions of the oceans. They are both flat shaped. In the system of classification, both organisms differ only in the order they belong to.
Rays and skates have few structural differences, however, one major difference between these two species of aquatic organisms is in their MODE OF REPRODUCTION.
- Rays have a VIVIPAROUS mode of reproduction i.e give birth to their young ones live.
- Skates have an OVIPAROUS mode of reproduction i.e. they lay fertilized eggs in cases called "mermaid's purses".
Answer:
c) rays give birth to live offspring, while skates lay eggs
Explanation:
The major difference between rays and skates is that rays give birth to live offspring (they do not lay eggs).

if 40 carabaos live in a 4 sq. meter area,what is their population density per sq. km.?
Explanation:
Given parameters:
Number of carabaos = 40
Area of the place = 4m²
Unknown:
Population density = ?
Solution:
The population density of the place is the number of organisms per square km.
Mathematically;
Population density = [tex]\frac{number of Carabao}{Area}[/tex]
Population density = [tex]\frac{40}{4}[/tex] = 10carabaos/m²

In allium, interphase lasts about 15 hours, and mitosis takes up 80 minutes. Assuming that
each stage of mitosis takes the same amount of time, how many hours old is a cell that is just
starting anaphase. (Yes, you'll need to do some math here - show your work or explain your
reasoning)
Answer:
15 hours and 40 minutes
Explanation:
The stages of mitosis are prophase, metaphase, anaphase and telophase. Anaphase is the stage of mitosis after metaphase where replicated chromosomes are segregated to opposite poles of the cell. Anaphase is the third stage after prophase and metaphase, which in this case have the same duration (20 minutes each one). In consequence, a cell that is just starting anaphase is 15 hours and 40 minutes old.
Interphase: 15 hours
Prophase: 20 minutes
Metaphase: 20 minutes
Knowing that interphase lasts 15 hours and each stage of mitosis lasts 20 minutes, we could say that a cell that is starting anaphase is 15 hours and 40 minutes old.
-------------------------------------
Available data:
The interphase lasts 15 hoursMitosis lasts 80 hours in totalEach stage of mitosis takes the same amount of timeNow, from the theoretical framework, we know that the interphase precedes the mitosis event.
We also know that mitosis is complete after four stages:
ProphaseMetaphaseAnaphaseTelophaseSo if the cell of interest is just starting anaphase, it means that it has already gone through the interphase. Then the cell has gone through the 15 hours that the interphase takes.
If mitosis is complete in 80 minutes, and each of the four stages lasts the same, we just need to divide 80 on 4 to get the amount of time each stage takes.
80 minutes / 4stages = 20 minutes/stage ⇒ Each stage takes 20 minutes
to complete.
This cell is just beginning the anaphase, which means it has already gone through prophase and metaphase. Each of them lasted 20 minutes.
So this cell has gone through 15 hours of interphase + 20 minutes of prophase + 20 minutes of metaphase = 15 hours and 40 minutes.
We can say that this cell is 15 hours and 40 minutes old.

What affects the function of enzymes
Answer:
I think this is right......
Explanation:
Enzyme activity can be affected by a variety of factors, such as temperature, pH, and concentration. Enzymes work best within specific temperature and pH ranges, and sub-optimal conditions can cause an enzyme to lose its ability to bind to a substrate.
