true breeding parents ______ trait variant(s) to there offspring A might only pass 1 B will pass 2 C can only pass one D will not pass
True breeding parents might only pass one (1) trait variant to their offspring (Option A).
What is true breeding?A true-breeding can be defined as a special type of mating where parents produce offspring that have the same phenotype.
True breeding occurs when parental lines having a given phenotype generate descendence with this same phenotype.
These parents need to be homo-zygous, i.e., they need to have the same gene variant or allele, for the trait to be inherited.

one difference between viruses and cells is that viral particles have a..?
a nucleic acid within a capsid
c membrane-bound cytoplasm
b cell wall within a capsule
d membrane-bound chromosome
One major difference between viruses and other cells is that viral particles have nucleic acid located within a capsid.
Structure of a virusViruses are made up essentially of ribonucleic or deoxyribonucleic acids enclosed in a proteinous shell known as capsids.
This is unlike other cells in which their nucleic acids either lie freely within the cytoplasm of their cells or are enclosed in a double membrane structure known as the nucleus.
Viruses are essentially non-living when outside a living host.

no chlorophyll or chloroplasts
no cell wall, only plasma membrane
Answer:
large hypertonic vacuole
cell plate in cell divison
Explanation:
All other options are for animal cells.
Answer: select the 1st and 3rd
Explanation:
Plant cells divide in two by constructing a new cell wall (a plate) A plant cell has 1 large vacuole while an animal cell has more than 1 vacuole which is smaller compared to the vacuoles of a plant cell.

bear can live. If polar bears do not have adaptations that allow them to survive
these changes, what may happen to them?
A They may become extinct.
B They may overpopulate.
C They may change the environment.
D They may become another species.
Answer:
A.
Explanation:
If they have know where to live, they can't overpopulate. The question ask what will happen to the polar bears so C can no be it. Polars Bears do not have the features for them to become another species.
What are invasive species? how do they impact the ecosystem
Answer:
disorder in the ecosystem
Explanation:
Invasive species are organisms from different ecosystems that somehow find their way to a different one. The ecosystem that they arrive in cannot be prepared to receive them and the invasive species, these species may not have predators or characteristics that help them to feed or reproduce quickly. This causes a disorder in the ecosystem that can wipe out entire species and if a species disappears in a chain many others will be affected.
Assume all of the presynaptic synapses identified produce epsps. If two of these synapses fired simultaneously, which synaptic combination brings the initial segment closest to threshold based on spatial summation?.
The synapses that are nearer to the axon hillock would bring the initial segment closest to the threshold based on spatial summation.
What is neuron synapsis?In neurosciences, the term synapsis makes reference to the connection between two nerve cells (neurons).
Synapsis is produced by the connection between axons and dendrites among different neurons.

Natural selection does not create adaptions, mutations, or variations. Natural selection causes the extinction of individuals who are not well adapted to changes in the environment. Natural selection can also provide reproductive advantages for some individuals over other individuals.
What is the difference between force and net force?
Don't copied from goo-gle
Force
- Force is defined as the act of pushing or pulling of an object. It can influence and alter the motion of an object.
Net Force
- Unlike Force which only defines a push or pull, Net Force is the combination of all forces acting on an object. The Net Force can be computed through Newton's Second Law, F=ma.

Paragraph 3 describes the diagram at the top of this article. It demonstrates:
A: that energy flows in one direction beginning with light energy
B: the transportation of sugars into mitochondria
C: the Krebs Cycle
D: the Calvin Cycle
Photosynthesis involves a series of reactions including trapping of sunlight energy and the Calvin cycle through which plants make their food in the form of sugars.
What is metabolism?Metabolism refers to the sum of reactions that occur in a living organism which helps obtain energy and remove waste in order to sustain the life of an organism.
Different metabolic reactions take place in plants and animals.
In plants, energy is obtained from the sun and is used to drive photosynthesis.
The sugars made in photosynthesis are stored in roots, stem and tubers as well as in fruits.
The sugars can be broken down to produce energy in th mitochondria.
The Calvin cycle is the process that plants use to convert carbon dioxide and water to sugars
The Krebs cycle is a cycle which produces molecules which are used to produce energy in the mitochondria.
Therefore, since the diagram is not attached, the process shown can be understood from the explanation of each process in photosynthesis and metabolism.
