Two species of three-spined stickleback fish have been found together in five different lakes. The larger, bottom-dwelling species feeds on large prey close to shore. A surface-dwelling species feeds on small plankton in open water. DNA analysis shows that the two species in each lake are more closely related to each other than they are to any of the other species in the lake. Which prezygotic mechanism most likely allowed divergence of an ancestral species into these present-day species
Answer:
The answer is "Sympatric speciation due to disruptive selection"
Explanation:
Disruptive selection is a certain type of natural choice, that aggressively favors all ends of the spectrum in a moderate community. Disruptive selection is often deduced by a phyletic prepared to change to contribute to speciation. These two species happened due to various habitats associated with extreme speciation due to various confusing choices.
How might the loss of sea ice affect people, animals, or ecosystems?
(Marking as Brainliest for correct answer)
Answer:
The Global Impacts of Arctic Sea Ice Loss. Some of the most important climate news this winter has been around the alarming lack of sea ice in the Arctic, which has been in decline due to the steady rise in Earth’s average air and ocean temperatures. While suffering polar bears are a poignant symbol of climate change, the effects of disappearing ice extend far beyond the Arctic circle and its inhabitants.

Where does natural variation in a population come from? *
1.mutation
2.crossing over
3.sexual reproduction
4.independent assortment
5.natural variation comes form all of these
Explanation:
Genetic variation can be caused by mutation (which can create entirely new alleles in a population), random mating, random fertilization, and recombination between homologous chromosomes during meiosis (which reshuffles alleles within an organism's offspring).
Answer:
The answer is Mutation.

Which statements about tsunamis are true?
They are powerful ocean waves.
They are less destructive than typical wind-caused waves.
Earthquakes can stop them from causing flooding.
Underwater landslides can cause them.
Coastal areas are safe from them.
Answer:
they are powerful ocean waves and Underwater landslides can cause them.
Explanation:
Typical wind-cause waves aren't destructive, earthquakes make them too, coastal areas are more in danger then other areas so it's those two.
The true statements about tsunamis are, that they are powerful ocean waves, and underwater landslides can cause them.
What do you mean by Tsunamis?Tsunamis may be defined as the giant oceanic waves under the sea that are caused either by an earthquake or a volcanic eruption.
An earthquake is a resulting factor for tsunamis which are more destructive than typical wind-caused waves.
The coastal areas are more reckless from tsunamis as compared to the middle area.
Therefore, the true statements about tsunamis are, that they are powerful ocean waves, and underwater landslides can cause them.

plz help!!! If this is a sequence of one DNA strand, what is the complementary sequence of the other DNA strand? DNA: A T T C A G C G A
Answer:
T A A G T C G C T
Explanation:
DNA strand: A T T C A G C G A
complementary DNA strand: T A A G T C G C T
This is a very important rule:
Four kinds of nitrogenous bases in DNA: Adnine (A), Thymine (T), Guanine (G), Cytosine (C)
And this is how they're coupled:
A = T
C = G
For example::
First DNA strand: A T G C

Describe the 3 types of cell division that complete the cell cycle. What types of cells do these types of cell division occur in?
Answer: The cell cycle is composed of interphase (G₁, S, and G₂ phases), followed by the mitotic phase (mitosis and cytokinesis), and G₀ phase. here are two types of cell division: mitosis and meiosis. Most of the time when people refer to “cell division,” they mean mitosis, the process of making new body cells. Meiosis is the type of cell division that creates egg and sperm cells.

Explain with scientific reason that origin of life was associated with some chemical reactions.
Answer:
Darwin's theory of biological evolution tells us that all life on earth may have originated from a single, relatively simple reproducing creature living in the distant past. This idea is based on many observations, one of which is that when living things reproduce, children are often born with random new traits.

Answer: i believe it is not all solar energy is used for photosynthesis
Explanation:
The following is not true concerning the flow of energy through an ecosystem: "Not all solar energy is used for photosynthesis," which is in Option C, as most of the solar energy that reaches the earth is captured by plants through photosynthesis.
What is the energy flow through ecosystems?Energy flows through ecosystems in a one-way direction, from the sun to producers (such as plants) and then to consumers (such as animals). The energy that drives this flow is primarily provided by the sun, which emits solar radiation that is absorbed by plants and other photosynthetic organisms. During photosynthesis, plants use the energy from sunlight to convert carbon dioxide and water into glucose (a sugar) and oxygen. This process captures some of the solar energy and stores it in the chemical bonds of glucose, which can then be used as a source of energy by the plant itself and by other organisms that consume the plant.
Hence, the following is not true concerning the flow of energy through an ecosystem: "Not all solar energy is used for photosynthesis," which is in Option C.

by the data if...
A. traits independently assorted in
approximately a 9:3:3:1 ratio.
B. the traits for white fur and red eyes were
always inherited together.
C. all the F1 offspring had the same phenotype.
Answer: B
the traits for white fur and red eyes were always inherited together.
Explanation:
The hypothesis would not have been supported by the data if the traits for white fur and red eyes were always inherited together by the law of independent Assortment.
What is law of independent Assortment?The law of independent assortment selects alleles of two extra genes into gametes independently of each other.The allele acquired for one gene is unrelated to the allele obtained for another.Mendel's experiment constantly shown that the progeny's distinctive combinations are always unique from their parents'.He formulated the Law of Independent Assortment on this premise.So we can conclude that as the qualities for white fur and red eyes are not usually inherited together, we may deduce that the two features are regulated by distinct genes and are independently shown in the person, as stated by the law of independent Assortment.
