Answer:
36750J
Explanation:
Potential energy, which is the energy of a body at rest or in a position is calculated as follows;
P.E = m × g × h
Where;
m = mass (kg)
g = acceleration due to gravity = 9.8m/s²
h = height of the boulder (m)
According to the provided information;
m = 25kg, h = 150m
Using P.E = m.g.h
P.E = 25 × 9.8 × 150
P.E = 36750 Joules

Achromoplast stores while a leucoplast stores A. starch; pigments B. chlorophyll; starch C. pigments; chlorophyll D. pigments; starch
Answer:
D. pigments; starch.
Explanation:
A cell can be defined as the fundamental or basic functional, structural and smallest unit of life for all living organisms. Some living organisms are unicellular while others are multicellular in nature.
A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells.
In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles.
A chromoplast can be defined as a heterogeneous organelle or plastids that is typically responsible for pigment synthesis and their storage in a plant. The pigments include red, orange, yellow or chlorophyll.
On the other hand, leucoplast is a colorless plastid i.e plastic lacking photosynthetic pigments that are typically found in storage organs, underground stems, cotelydons, roots, tubers, seeds, or endosperm etc., used for the storage of starch in the absence of sunlight.
Hence, a chromoplast stores pigments while a leucoplast stores starch.

Why might DNA mutation occur?
if the same amount of DNA remains
unchanged for too long
if there is a genetic code that tells the DNA to
mutate
o if DNA only receives information from one
gamete
O if there is a change in DNA that alters or
affects the genetic code
DONE
Explanation:
it can result from DNA copying mistakes made during cell division,exposure to chemicals called mutagens or infection by viruses

a. When neutral variations are passed on to the next generation they benefit the population
b. When harmful variations are passed on to the next generation, they have very little effect on the population
c. When variations occur, they change the way genes are passed along in a population
d. When helpful variations are passed along to the next generation, the offspring are more likely to survive and reproduce, which benefits the population

In a grassland ecosystem, a prolonged drought has caused depletion in food sources for a species of rabbit. Which of the following would allow for the population of rabbits to recover from the drought?
A) Genetically diverse population, with some rabbits able to survive with fewer water resources than usual
B) The population of rabbits must reduce its rate of reproduction to produce only the most fit offspring
C) Individuals of the rabbit population should have less genetic diversity to become more similar and evolve in the same direction
D) Individuals of the rabbit population must develop traits that make them better adapted to fewer water resources
Answer:
Genetically diverse population, with some rabbits able to survive with fewer water resources than usual

A normal body cell of a coyote has 78 chromosomes in its nucleus. What are the diploid (2N) and haploid (N) numbers of the coyote? How many chromosomes would be in each coyote gamete?
Answer:
39, 78 I think I'm so sorry if I'm wrong
The the diploid (2N) have 78 chromosomes and haploid (N) will have 39 chromosomes in the coyote.
What is diploid and haploid?A cell with a single set of chromosomes is referred to as haploid. The term haploid can also refer to the number of chromosomes in gametes, which are egg or sperm cells.
A diploid cell is one that has two copies of each chromosome. Each chromosome is carried by nearly all cells in the human body in two homologous, or similar, copies.
The only exception are germ line cells, which produce gametes, or egg and sperm cells.
A normal coyote body cell has 78 chromosomes in its nucleus, a diploid (2N) has 78 chromosomes, and a haploid (N) has 39 chromosomes.
Thus, the chromosomes in each coyote gamete will be 78 in diploid cell and 39 in haploid cell.

What are the properties of seismic waves, sound waves, and the different types of electromagnetic waves?
Answer:
they have different frequencies
Explanation:
All electromagnetic waves have various same properties like reflection, refraction, interference, and diffraction.
What are electromagnetic waves?The oscillations between an electric field and a magnetic field produce waves known as electromagnetic waves or EM waves. In other words, magnetic and electric fields oscillate to form electromagnetic (EM) waves. An electromagnetic wave's magnetic and electric fields are parallel to one another and to the wave's direction.
Electromagnetic waves include radio waves, television waves, microwaves, sound waves, seismic waves, and infrared waves. The only thing separating them is the wavelength. The distance between each wave's peak and the next is called the wavelength.
They have properties of reflection, refraction, diffraction, and interference.
