When can natural selection lead to evolution in a population?
A. If the environment of the population is stable and provides
resources
B. If the individuals in the population have very little genetic variation
C. If the population has unequal numbers of parents and offspring
D. If the frequency of the alleles for a trait in the population changes
Answer:
D
Explanation:
process of elimination
we'd want limited resources, genetic variation and parent-offspring ratio doesn't matter
Answer:
It’s D
Explanation:

Which type of reproduction involves the passing of characteristics to offspring? A. only sexual
B. only asexual
C. both sexual and asexual
D. neither sexual or asexual
Answer:
C. both sexual and asexual
Explanation:
In both cases, the parent(s) of the offspring pass down characteristics. Asexual reproduction makes a carbon copy of the parent so they would obviously have the parent's characteristics. Sexual reproduction passes down characteristics of both parents to the offspring.
How could injury to the excretory system affect the body’s ability to maintain homeostasis? Explain.
answer it first and ill make braniliest
Answer:
The excretory system maintains homeostasis (balance of body) within the body by expelling wastes. These waste products can assist in balancing electrolytes within the body. For example, you've got an overdose intake of medicines or vitamins, the kidneys and therefore the liver work together to be ready to metabolize the surplus meds.

Explanation:
Histones are 8 subunit proteins that cells use to pack DNA into the manageable condensed chromosomes you are used to seeing during mitosis or meiosis (functioning somewhat like hair rollers for DNA). Under normal circumstances, DNA binds TIGHTLY to histones. Given what you know about DNA structure, predict which amino acids are concentrated on the outer surface of histones that interacts with the backbone of DNA?
Answer: Arginine and Lysine
Explanation:
Histones are protein that packs DNA into nucleosomes. It compose of Arginine and Lysine amino acids.
Lysine and Arginine are basic amino acids that aids the solubility of Histone in water and also aids the interaction of DNA and Histones.
The amino acids that are concentrated on the outer surface of histones and interact with the backbone of DNA are ARGININE and LYSINE, which are positively charged (i.e., they are basic amino acids).
In eukaryotic cells, Deoxyribonucleic acid (DNA) is tightly packed by its interaction with histone proteins. A nucleosome is the functional and structural unit of eukaryotic chromatin, which is composed of an octamer of histone proteins (two subunits of H2A, H2B, H3 and H4 histone proteins) and approximately 147 base pairs of DNA.The phosphate backbone of the DNA double helix is negatively charged because phosphate bonds between phosphorous atoms and oxygen atoms have a negative charge.In consequence, the tight wrapping of DNA around histones is due to the attraction between the phosphate backbone of the DNA molecule and positively charged amino acids of histones.In conclusion, the amino acids that are concentrated on the outer surface of histones and interact with the backbone of DNA are ARGININE and LYSINE, which are positively charged (i.e., they are basic amino acids).

how the structure of synapse ensures that impulses travel in one direction
Synapse
It carries information through electrical impulses to the cell body.
It is the gap between neurons.
It ensures that information travels in one direction only.
Explanation:
A synapse is the gap or the junction where two or more neurons or nerve cells meet together.
Also called the synaptic cleft, the synaptic gap receives the electrical signals and passes them through one nerve cell to another
The axon nerve endings release neurotransmitters which ensure that the path of transmission of impulses is only unidirectional – only from presynaptic to postsynaptic path.
The synaptic gap between a nerve cell and an effector muscle cell is referred as the neuromuscular junction.

100 POINTS. What is the difference between a learned behavior and an inherited behavior? Give one example of each. Please will mark brainliest.
Answer:
An Inherited behavior is a behavior received from the parents through genetics such as long legs for speed while a learned behavior is a behavior in wich an animal has to learn by itself by looking at past experiences such as baby ducks learning how there mother duck avoids danger.
Explanation:
Answer:
A learned behavior is more a behavior that is learned from experience of an organism. An example is imprinting, in which a young animal comes to recognize (another animal, person, or thing) as a parent or other object of habitual trust.
An inherited behavior is one that is innate, something that is bestowed upon an organism at birth. An example is animals starting to instinctually prepare for winter as the weather turns cold during the fall.
Gradually you notice that the large chamber walls seem to be closing in. You hear a thundering boom, and the whole chamber vibrates as the valve slams shut above you.

"After scanning the green labeled areas and the red labeled areas, when we combine the two images, the spots that show up as yellow correspond to "
Answer:
... areas labeled both red and green.
Explanation:
The spots that show up as yellow correspond to areas labeled both red and green.
__
The effect of combining images will depend on the method used to create the combination. There are many possibilities when combining color images.
When mixing red and green light, yellow light is produced. When mixing red and green pigment, brown pigment is produced. When mixing digital representations of red and green, the effect depends on the individual representations, the method of mixing, and the interpretation of the mixed result.
__
Given the way the question is worded, we assume that yellow is produced by a combination of red and green appearing in the same area of the images. That is, ...
The spots that show up as yellow correspond to areas labeled both red and green.

What does it mean if you find a skeleton and all of the sutures on the skull are fused? Be specific by using ages in your explanation.
(Forensics)
Answer:
If the scull is fused the individual is not a baby
Explanation:
If a skull is found, one of the first things to do is classify by age. Careful observation will show that the skull may or may not be fused. Noteworthy observations could give the professional an idea of the individual's age.
In the womb when the bones of the skull are being formed thre are typically seven bones with gaps in between. This allows the infant to pass safely through the birth canal but giving way to squeezing and the contractions of the uterus. After the child is born there are still remaining gaps. These gaps allow the brain to grow and develop without pressure from the skull. This can often be observed by a soft spot on the top of the infant's head sometimes called a "mole"
Around two years of age, these bones begin to fuse and harden. Therefore if a skull is found with fused bones, the individual can be placed to be older than two years of age. Other determining factors such as teeth etc can narrow down the individual's age.

explain the process (reflex action) that happens when you pull your arm away from an open flame. use steps to explain your answer. identify the receptor in the skin, the stimulus, the neurons,the effector(muscle) and the body's response to the stimulus.
Answer:
A reflex action is defined as an involuntary action of body in response to a stimulus, which protects the body from any harmful conditions including touching open flame.
A reflex action follows a sequence of action that helps in involuntary action, tha include the stimulus, receptor in the skin, the neurons (sensory, relay and motor neurons), the effector(muscle) and resposne of body to stimulus.
In the reflex action when a person pull his/her arm away from an open flame, the stimulus will be the hot flame that send a signal to the nervous system.
The sensory receptor found in the dermis or epidermis of skin called cutaneous receptors, senses the temperature change.
Then the sensory neuron comes in action which sends electrical impulses to a relay neuron (located in spinal cord) and relay neuron sends impulse to motor neuron.
Motor neuron sends that electrical impulses to a muscle which act as an effector which allows muscle to contracts to move hand away.
So, at the end the body resposnes to move hand aways from the open flame.
