This statement is True. DNA profiling can be used to trace the evolutionary history of organisms. By comparing the DNA sequences of different organisms, scientists can determine the degree of relatedness between them and construct evolutionary trees that show how different species are related to each other.
DNA profiling can also be used to study the genetic variation within populations and to track the movements of organisms through space and time. For example, DNA profiling has been used to study the migration patterns of human populations and the evolution of different animal species. Overall, DNA profiling provides a powerful tool for understanding the evolutionary history of organisms and their relationships to each other.

find out what do the terms algal bloom and red tides signify
Answer:
Find out what do the terms 'algal bloom' and 'red-tides' signify. Algal bloom refers to an increase in the population of algae or blue-green algae in water due to an enrichment of nutrients, resulting in discoloration of the water body. ... Red tides are caused by red dinoflagellates (Gonyaulax) that multiply rapidly.
I hope it's helpful!
Answer:
Algal bloom refers to vigorous growth of algae or blue-green algae in water, due to enrichment of water body with minerals nutrients coming from fields, resulting in discoloration of the water body. This causes an increase in the biological oxygen demand (BOD), resulting in the death of fishes and other aquatic animals, due to suffocation.

the FUNCTION of enzymes. YOU MUST USE
THE WORDS CATALYST, ACTIVATION
ENERGY, RECYCLABLE
Answer:
Enzymes help speed up chemical reactions in the human body. They bind to molecules and alter them in specific ways. They are essential for respiration, digesting food, muscle and nerve function, among thousands of other roles.
What is the function of an enzyme? They allow chemical reactions to occur at normal body temperature fast enough to sustain life. They reduce the activation energy needed to start a chemical reaction.
There are four steps in the process of an enzyme working. (1) An enzyme and a SUBSTRATE are in the same area. The substrate is the biological molecule that the enzyme will work on. (2) The enzyme grabs onto the substrate with a special area called the ACTIVE SITE.

Enzymes create chemical reactions in the body. They actually speed up the rate of a chemical reaction to help support life. The enzymes in your body help to perform very important tasks. These include building muscle, destroying toxins, and breaking down food particles during digestion.

Mitosis vs Meiosis, someone help me with this, ill give brainiest.
♡ hi there!! i tried to go back to my notes, but i couldn't find anything. but here if an explanation i found. ♡
different: mitosis consists of one stage whereas meiosis consists of two stages. mitosis produces diploid cells (46 chromosomes) whereas meiosis produces haploid cells (23 chromosomes). mitosis produces two identical daughter cells whereas meiosis produces four genetically different daughter cells.
similar: both involve cell division, both the processes occur in the M-phase of the cell cycle. In both cycles, the stages are common – metaphase, anaphase, telophase and prophase. synthesis of DNA occurs in both.

2. Codominance: Diricrawls are plump, fluffy-feathered, flightless birds. Feather color
is co-dominant; FF have pink feathers, PP have purple feathers and mottled diriclaws (FP)
have both pink and purple feathers. Pink feathered diricrawls are very rare and prized by
collectors. If you breed a pink diriclaw with a mottled diricrawls, what percentage of their
offspring will be pink feathered? (show all of your work and use a Punnett square).
Answer:
The correct answer is - 50% or 1/2.
Explanation:
In codominance both alleles express their traits and blend to make new traits, there is no dominance or recessive pattern found. In this question, there is FF have pink feathers, PP has purple feathers and mottled diriclaws (FP). Then a cross between pink feathers and mottled diriclaws would produce offspring:
F F
F FF FF
P FP FP
Here two out of four have pink feathers. That is 50%

Secon2015
I NEED TO KNOW ASAP
Answer:
A. Mid-ocean ridge. I'm not sure if I'm right.
The place where the new volcanoes are less likely to be seen is mid-ocean ridge. The correct option is A.
What is volcano?A volcano is a crack in the crust of a planet, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber beneath the surface.
Volcanoes are most commonly found where tectonic plates are diverging or converging on Earth, and the majority are found underwater.
Although Australia is the only continent with no active volcanoes, it does have one of the world's largest extinct volcanoes, the Tweed Volcano.
Volcanism is directly related to plate tectonics theory. Volcanoes are only found at specific types of plate boundaries, and only rarely in the middle of ocean plates.
Thus, the correct option is A.

Explanation:
In three to five sentences, construct an argument that shows why lichens are necessary to establish a new ecosystem after an extreme disturbance.
I would really appreciate it if someone o two people would help me out on this one
Answer: Lichens affect every species in the ecosystem, in 2013 Russia had a dramatic lichen die off which caused 61,000, 20% of the entire reindeer population to die from starvation. And with fewer deers, the bears and wolves also suffered from the loss of lichens and if it takes a long time for lichens to grow back in an ecosystem, animal declines may take years if ever to be corrected. Lichens serve as a basis for several food chains, especially in artic communities.
The argument which shows why lichens are necessary to establish a new ecosystem is as follows;
Lichens are known to enable algae to live all over the world in many different climates.
On this note, lichens also provide a means to convert carbon dioxide in the atmosphere through photosynthesis into oxygen, a process required by all to survive.
Additionally, lichens provide us with valuable information about the environment around us.
On this basis, lichens are important for establishing a new ecosystem after an extreme disturbance.
