CELLS
whats a cell
In biology, a cell is a membrane-bound unit that contains the basic components of life and is made up of which all living organisms are made. A single cell, such as a bacterium or yeast, is frequently a complete organism in and of itself. As cells age, they develop specific roles.
producer
Autotrophs are organisms that produce their own food using photosynthesis. Because they are devoured by other species, they are at the bottom of the food chain.
food web
in an ecological community, the entirety of interconnected food chains.
a mutation is a change in___
genetic material -DNA
Who discovered gunpowder and what is it made from?
China. It is a mixture of potassium nitrate, charcoal, and sulfur.
difference between prokaryotic and eukaryotic cell
Eukaryotic cells contain a membrane-bound nucleus, whereas prokaryotic cells do not. In eukaryotes, the nucleus is just one of numerous membrane-bound organelles. Prokaryotes, on the other hand, lack organelles that are attached to the membrane.
consumer
A heterotroph is a creature that feeds on other creatures or organic debris because it lacks the ability to produce its own sustenance from inorganic sources.
food chain
the process of substance and energy being transferred from one creature to another in the form of food.
T OR F Mutations are not random
false
What is an explosion?
An explosion is a sudden violent conversion of potential energy into work which transfers to its surroundings in the form of a rapid rise in pressure called a blast wave or shock wave
difference between plant and animal cell
A huge, isolated vacuole exists in each plant cell, which is utilized for storing and preserving the cell's structure. Animal cells, on the other hand, have a lot of tiny vacuoles. Plant cells have both a cell wall and a cell membrane. There is no cell wall in animal cells, only a cell membrane.
decomposer
a heterotroph is a creature that feeds on other creatures or organic debris because it lacks the ability to produce its own sustenance from inorganic sources
population
All of the individuals of a particular species living in an area
Genes code for proteins and these proteins make up different ___
traits
Why is gunpowder not an effective explosive?
produces copious amounts of smoke in the process, making it an inherently messy explosive.
What are the 4 different types of cells?
Epithelial Cells, Nerve Cells, Muscle Cells, and Connective Tissue Cells.
Secondary consumer
secondary consumers are creatures that get energy from primary consumers. Secondary consumers, on the other hand might be carnivores or omnivores
ecosystem
all of the living and nonliving things interacting together
Insertion mutation means
an extra base is added in
What is potential energy?
potential energy is energy stored which can be released in an explosion.
In the human body, how many distinct types of cells are there?
In the human body, there are around 200 distinct kinds of cells.
tertiary consumer
Tertiary consumers, often known as apex predators, are typically found at the top of food chains,
.
community
a group of populations of 2 or more species
What is a "FRAMESHIFT" mutation?
when everything after the mutation gets messed up
How do cars utilize explosions?
cars create a little explosion to move the pistons of their motor in order to create the power that moves the vehicle.
