When interspecific interactions lead to competitive exclusion, the weaker competitor is forced to retreat to a more restricted niche (its realized niche) than it otherwise would inhabit in the absence of the competition (its fundamental niche). This is what happens between Balanus and Chthamalus
Answer:
The places where the species can thrive principally because of its characteristics is known as the fundamental niche, on the other hand, the place where the species is living is known as the realized niche. In the intertidal region, the species Balanus and Chthamalus compete for space. In comparison, Balanus is a bigger barnacle that can colonize the place more effectively than Chthamalus.
This competition for space makes Chthamalus displace into higher regions where water is not the same as in lower levels. The fundamental niche of Chthamalus comprises both lower and higher levels, while the realized niche for Chthamalus is the higher levels. In case, if the competition with Balanus was non-existent, the Chthamalus would occupy the lower levels.
In an experiment, the presence of an____is manipulated by the researchers so that it affects may be determined
Answer: independent variable
Explanation:
define analogous structure and provide an example
Analogous structures are structures that are similar in unrelated organisms. The structures are similar because they evolved to do the same job, not because they were inherited from a common ancestor. For example, the wings of bats and birds, shown in Figure below, look similar on the outside.
Similar features in unrelated organisms are referred to as analogous structures. These structures are comparable not because they have a shared ancestor but because they accomplish the same task. Sharks and dolphins, for instance, even though they are unrelated, both have fins.
What is an analogous and homologous structure?Analogous structures, as opposed to homologous structures, are traits of different species that evolved in response to a similar environmental challenge and are similar in function but not necessarily in structure.An insect's wings and a bird's wings are similar in structure. Although each of these species utilise their wings to fly, the origins of their wings are different.Analogous organs have comparable functions, while homologous tissues share a similar embryonic origin.For instance, the bones in a human arm and a whale's front flipper are anatomically similar.The constructions here are not comparable. A butterfly's wings and a bird's wings are analogous but not homologousTo learn more about analogous structure, refer to:

d. a process that occurs as a result of differences in reproductive fitness.
e. a process that occurred only in the past.
Answer the lab question, "What is the effect of the
inheritance of one trait on the inheritance of a
second trait?" with a hypothesis. Remember that
you can either assume that the two genes are
independent or that they are linked. What results
would you expect in either case?
Hypothesis:
Answer:
Sample Hypothesis: If a mouse inherits a particular form of one trait, then the inheritance of the other trait will not be affected because alleles assort independently.

Which feature on its head has a structure that enables the animal to eat its
food? Sea lion
A. Eyes
B. Nose
C. Mouth
D.whiskers
Sea lion eat using whiskers.
Marine creatures known as sea lions are frequently spotted along ports and coasts all over the world. They are trained for tasks and frequently used in shows due to their high intelligence.Sea lions hunt by diving under the water and using their vibrissae to look for fish. Excellent predators, sea lions catch and consume several fish each day. Their vibrissae are one of the greatest weapons sea lions utilize when hunting. Long hairs called vigrissae that surround the mouth are frequently referred to as whiskers.As carnivores, sea lions eat clams, hake, squid, crabs, and octopus. They are predatory marine animals that only eat marine life. They are coastal-dwelling creatures that pursue their prey using wits and swimming prowess.Therefore, option D. is correct.

ATP is a(1 point)
storable form of energy.
usable form of energy.
form of energy that can be used and stored.
form of energy that can be stored and released as heat.
Hello there!
Your answer should be ATP is a stored form of energy.
You see, Think of it as the “energy currency” of the cell. If a cell needs to spend energy to accomplish a task, the ATP molecule splits off one of its three phosphates, becoming ADP (Adenosine di-phosphate) + phosphate. The energy holding that phosphate molecule is now released and available to do work for the cell. Hope this works!
Answer:
a storable form of energy

If the sperm of a boa constrictor has 18 chromosomes, how many chromosomes will each skin cell of the snake have?
Answer:
18 chromosomes
Explanation:
If the sperm of a boa constrictor has 18 chromosomes, the number of chromosomes that each skin cell of the snake will have is 36 chromosomes.
What is meiosis?Meiosis is the process of gamete formation where each daughter cell or gamete contains half the number for f chromosomes as the parent cell.
According to this question, the sperm of a boa constrictor has 18 chromosomes. The sperm is a gamete formed as a result of meiosis.
Therefore, If the sperm of a boa constrictor has 18 chromosomes, the number of chromosomes that each skin cell of the snake will have is (18 × 2) = 36 chromosomes.

If shaded symbols indicate having a dominant trait, what must be the genotype of the father in this pedigree chart?
Answer: The father must have a hetero'zygous genotype since both his offspring show the recessive trait even though he shows a dominant trait!
Answer:
Heterozygous
Explanation:
The offspring both carry recessive genes. The recessive gene will show up more often if one of the parents are heterozygous of the gene along with the other having recessive.
If the father was had both of the dominant traits, the offspring would inherit his trait instead.

Becky has been asked to provide an example of how carbon is converted from a living form to a non-living form.
Which example should she use?
O Carbon dioxide in the atmosphere is absorbed by an ocean.
O Sugar in animals is converted into carbon dioxide during cellular respiration
O Calcium carbonate in rocks is converted into sediment through weathering
O Carbon dioxide from the air is converted into sugars during photosynthesis.
Answer:
Carbon dioxide in plants is converted into sugars during photosynthesis
Explanation:
An example of how carbon is converted from a living form to a non-living form is as follows: sugar in animals is converted into carbon dioxide during cellular respiration.
CELLULAR RESPIRATION:Cellular respiration is the metabolic process whereby living organisms obtain energy by breaking down food molecules in their cells. During cellular respiration in animals, the sugar (living form) obtained from food molecules is oxidized and broken down into carbon dioxide, which is released into the atmosphere (non-living form).Therefore, an example of how carbon is converted from a living form to a non-living form is as follows: sugar in animals is converted into carbon dioxide during cellular respiration.
