Answer:
This would be an example of Directional Selection
Explanation:
Natural selection is the result of the phenotype-environment interaction which determines gene destiny in space and time, selecting beneficial alleles and increasing their frequency in the population.
Directional selection increases the proportion of individuals with an extreme phenotypic trait. This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
In the exposed example, Reddish Egret populations were under hunting pressure, which drove them to increase the frequency of dark-feathered individuals, as well as the frequency of the allele codifying for this trait. Dark individuals were the ones that got to survive hunting, they could reproduce and increase in number.
HELP ME I WILL GIVE BRAINIST AWANERR AND On a separate sheet of paper, choose three animals, one that lives in water, one that lives on
land, and one that flies. Explain how each one moves and how it is uniquely adapted for
movement within its environment.
Answer and Explanation:
Land - Lion
Water - Sealion
Flies - Bees
Lions have strong retractable jaws that help them eat their prey and that way they adapt to their enviroment.
The Sealion's thick, oily fur and a layer of blubber allow them to keep a high temperature in cold waters.
A Bees body carries an electrostatic charge that attracts pollen and that way they can keep it in them.

Why is animal testing bad?
Answer:
Explanation:
Animal experiments may result in clinical trials of biologically faulty or even harmful substances, thereby exposing patients to unnecessary risk and wasting scarce research resources. Animal toxicity studies are poor predictors of toxic effects of drugs in humans.
Answer:
Experimenting with animals is not justified with anything, they practically play with beings that have life, emotions and that feel pain like all living beings.
Advances the experiments that are done on them, are not used, or the purpose is simply lost, as well as their life.
how does density-independent limiting factors
can affect populations
Answer:
Density independent limiting factors also cause population sizes to increase. For example, the water from a flash flood increases the growth of vegetation, thereby providing more food for primary consumers in the ecosystem.

Selective breeding produces cultivated varieties of plants within the same genus. Cultivars often use ____
names following the genus, which are not based in Latin. For example, for a hybrid tea rose which is
black, it is called Rosa'Black Baccara'.
Answer:
Binomial
Explanation:
Answer:
The correct answer is - cultivar epithet.
Explanation:
Selective breeding results in cultivated varieties of plants of the same genus. These cultivated varieties are called cultivar names. This cultivar name consists of the scientific Latin botanical genus name followed by a name called as cultivar epithet.
Vernacular language is the full cultivar epithet of the species such as an example given here of herbal hybrid tea called Rosa 'Black Baccara'.

Which statement correctly describes the significance of meiosis during gamete formation?
Answer:
Explanation:
During sexual reproduction, meiosis generates genetic variation in offspring because the process randomly shuffles genes across chromosomes and then randomly separates half of those chromosomes into each gamete. The two gametes then randomly fuse to form a new organism.

How is the dispersive model different from the semiconservative model of DNA replication?
1. In the dispersive model, each strand of both daughter molecules contains a mixture of old and newly synthesized DNA, and in the semiconservative model, each new double helix consists of one old and one new strand.
2. In the dispersive model, the old double helix is degraded, and in the semiconservative model half of its nucleotides are used in the construction of two new double helices.
3. In the dispersive model, one of the two resulting double helices is made of two old strands, and in the semiconservative model the other is made of two new strands.
4. In the dispersive model, one strand of the new double helix is made of DNA, and in the semiconservative model the other strand is made of RNA.
Answer:
It it not, In the dispersive model, one of the two resulting double helices is made of two old strands, and in the semiconservative model the other is made of two new strands.
Answer:
option 1 is correct
Explanation:
in dispersive, each strand of DNA has alternating fragments of old and new DNA while in the semiconservative each new double helix consists of one old and one new strand.

Explanation:
Which factor can cause secondary succession?
clear cutting
glacial melting
competition
predation
Answer:
A
Explanation:
Clear cutting can cause secondary succession. Therefore, option (A) is correct.
Secondary succession is a type of ecological succession that occurs after a disturbance, such as a fire, flood, or clear-cutting of a forest.
Clear cutting refers to the process of removing all trees in an area, leaving behind a bare landscape. This can disrupt the natural balance of the ecosystem and create an opportunity for secondary succession to occur. After clear cutting, the soil is often left exposed and vulnerable to erosion, which can alter the physical and chemical properties of the soil. This can affect the types of plants and animals that can grow in the area, leading to a new community of organisms that gradually develops over time.

What are the differences between white blood cells and normal eukaryotic cells?
Answer:
White blood cells (WBCs) are specialized to respond to antigen and produce antibodies as well as undergo phagocytosis in response to toxic stimuli.
WBCs are part of immune system and there are five different kinds with specialized features.
In order to make a cell model, it is best to use a muscle cell and a nerve cell or neuron: there are pronounced structural differences and those are present throughout animal kingdom.
Lower animals ( such as insects, worms etc. ) have different immune system, however, they do have typical neuron and a muscle cell/skin cell (fibroblast). Such cell models are likely to be easy, distinct and bring you good grades without going through much complication and confusions of various organ systems and animal mod
