A result of natural selection is D) giraffes having increasingly more extended necks over time. Natural selection is an evolutionary mechanism that was offered by Darwin.
According to this mechanism, organisms that are better skilled of adapting to their changing environmental conditions, survive and grow their number through reproduction whereas other are stopped from the population.
Who discovered natural selection?
The theory of natural selection was studied by 19th-century naturalist Charles Darwin. Natural selection describes how genetic traits of a species may change over time.
What is natural selection and example?Natural selection is the process in nature by which organisms better adapted to their environment manage to persist and reproduce more than those less adapted to their environment. For example, treefrogs are sometimes consumed by snakes and birds.

Which best illustrates a result of natural selection?

The current taxonomic system is based on the Linnaean classification system.
All of the current, living species in the world have been cataloged.
Answer:
1) taxonomy
2) species
3) the animal has sharp, pointed teeth
4) the current taxonomic system is based on the Linnaean system
5) he only had two kingdoms, animals and plants
Explanation:
did the quich check
The statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.
Taxonomy is a field of study focused on naming and classifying groups of organisms according to their morphological and genetic features. The taxonomic system organizes species from larger to more specific taxonomic categories in a hierarchical system.The botanical taxonomist Carolus Linnaeus is considered the father of taxonomy because he was the first person to formulate a system for classifying different species of plants and animals.Nowadays, the taxonomic system includes eight (8) categories from larger to more specific: domain, kingdom, phylum, class, order, family, genus, and species.In conclusion, the statement 'the current taxonomic system is based on the Linnaean classification system' is TRUE.

Neurons that respond to specific types of lines are examples of:
A. figure detectors.
B. top-down processors.
C. feature detectors.
D. figure processors.
Answer:
C
Explanation:
Neurons that respond to certain types of lines are examples of feature detectors found in Option C. Neurons are the monomeric units of the nervous system that play an important role in transmission.
What is the importance of the neuron?
The neuron is a unit in which the message is transmitted from the neuron to another neuron, and this can be done by either chemical signaling or by electric signaling. The neuron receives sensory stimuli from the sensory organ and transmits them to the spinal cord.
Later, the message from the spinal cord is sent to the motor organs, and the whole pathway of the neuron signaling from the sensory to the motor organ is called the reflex arc. The neuron takes part in the signaling process so that the muscle can function, regulate the contraction relaxation, and perform many other functions.
Hence, neurons that respond to certain types of lines are examples of feature detectors found in Option C.

Why would cells from the same organism have different functions?
Answer:
Explanation: Cells have to fulfill multiple different functions to be able to build complex multicellular organisms. Differently expressed genes lead to different proteins made in the cell, which leads to different morphology, shape or function. ... When this factor cannot be expressed, these cells do not develop at all.

Hello My name Is Chloe, Do you think you can help me with My Question
I need Facts on sharks.
I'm doing a report for school.
Thanks:)
Answers:
Here are some fact about sharks that i found cool
#1
Possibly one of the most evolved sharks today are hammerhead sharks. They have an advanced sensory system and a body shape that has adapted to hunt specific prey
#2
Sharks may be one of the most important species on Earth. They have been maintaining our oceans for over 400 millions years.
#3
Sharks have evolved and changed much over millions of years. However many sharks today still share some of the features as sharks from millions of years ago.
#4
Sharks have been in our oceans for over 400 million years. Some of the earliest sharks were discovered dating back to the Devonian age.
#5
Sharks have survived five massive planet extinction events. These extinction events killed most life on earth and the last one around 65 million yeas ago killed the dinosaurs.
#6
There are over 500 species of shark.
#7
It is believed that each whale shark's pattern is unique, like a human's fingerprint.
#8
Sharks do not have bones. Instead, they have cartilage, that's what makes up human noses and ears
#9
According to the Smit.hsonian, there are over 500 known shark species, though many are endangered or declining due to various factors like overfishing.
#10
Your odds of getting attacked and killed by a shark are 1 in 3,748,067. In a lifetime, you are more likely to die from fireworks or lightning. Whereas over 100 million sharks are killed every year by humans.
#11
Whale sharks are the world’s biggest fish.
#12
Sharks mature slowly and reach reproductive age anywhere from 12 to 15 years.
#13
Hammerhead sharks' eyes are on the sides of their heads, so they have nearly a 360-degree sight line. Their panoramic view of the undersea world is inhibited by two blind spots, one in front of the snout and the other directly behind the head.
#14
Sharks predate the dinosaurs by 200 million years.
#15
Great whites can detect one drop of blood in 25 gal (100 L) of water and can sense even tiny amounts of blood in the water up to 3 mi (5 km) away.

Answer:
the right answer is option BThe illustration is a representation of multiple gene alleles on the same chromosome. One inherited trait linked to alleles "A", "a", "D", "D", "t", and "T" is determined by __________.
Answer:
A characteristic linked to the alleles that is inherited is the genotype.
Explanation:
The genotype is the genetic makeup of an individual. The genotype is determined by the alleles and is passed from father to son through the transmission of alleles, that is, the genotype is an inheritable characteristic. The genotype cannot be modified by the environment, nor can it be modified in a natural way, but it can be modified through mutations that are also inheritable.

How does an organism obtain CO2, H2O, and energy
to undergo photosynthesis?
Answer:
To perform photosynthesis, plants need three things: carbon dioxide, water, and sunlight.
Explanation:
By taking in water (H2O) through the roots, carbon dioxide (CO2) from the air, and light energy from the Sun, plants can perform photosynthesis to make glucose (sugars) and oxygen (O2).

The correct answer is C. Gardeners choose which plants they let reproduced based on the plant traits.
Explanation:
In general, selective breeding involves the intervention of humans in the reproduction of species, this includes mainly plant and animal species. Moreover, in selective breeding, humans choose which specific species or individuals reproduce to favor certain traits. For example, a farmer might allow only the biggest cows to reproduce because this will lead to bigger calves. In this context, the option that shows selective breeding is C because this shows the intervention of humans in reproduction by selecting the individuals that will reproduce.
4. Which statement is an example of how
environmental factors affect gene expression?
A. Your finger becomes callus from writing with a
pencil
B. The amounts of sun, water, and nutrients affect the
growth of a plant
C. Parents with red hair have a child with red hair
D. A red snapdragon flower is crossed with a white
snapdragon flower to produce a pink snapdragon flower.
Answer:
B. The amounts of sun, water, and
nutrients affect the growth of a plant
Explanation:
Gene expression is the way by which the genes of an organism instructs the production of proteins, which are responsible for the organism's phenotype. However, the trait or characteristics possessed by organisms are not strictly or 100% dependent on the genotypic factors but also on the environmental factors.
Environmental factors are the biotic (living) and abiotic (non-living) factors that affect organisms development and growth. An example is how the amount of sun, water, and nutrients, which are all environmental factors, affect the growth of a plant. Growth in plant, therefore, affects gene expression.
