Answer:
The correct answer is - option A. They evolved separately as they moved north and became two separate species
Explanation:
Greenish warbler is a leaf warbler present in many regions in the world and shows migration in winters in the Indian region. The main region of the migration is Tibetan Plateau.
They migrated from the southern part of these birds range and moved north and evolved separately from the main species and become two distinct species due to their geolocation and environment change.

Answer: Carbohydrates store the most energy.
Explanation:
Answer:
D. Lipids
Explanation:
Lipids store the most chemical potential energy. Carbohydrates are more readily available though so the body use carbs when it can before accessing lipid storages.

Emission lines are lines that are made when wavelengths of light are given off by cooling gases.
O True
O False
Answer:
Its FALSE on edge
Explanation:
When cooling gases emit light wavelengths, lines known as emission lines are created. The first people to notice constellations were the ancient Romans and Greeks.
What Emission lines that are made when wavelengths light?Monochromatic light has a single wavelength and is generated by lasers, which exploit transitions between two atomic energy levels to generate light with an extremely restricted range of wavelengths.
While emission lines refer to the lines of light produced by burning hot gas, absorption lines refer to the tendency of cool ambient gas to absorb the same lines of light.
Some light at specific wavelengths is scattered when it travels through the atmosphere's gas, producing darker bands.
Therefore, It is false that Emission lines are lines that are made when wavelengths of light are given off by cooling gases.

Please pick me as the brainiest. It would make my day
I am 100% sure that the correct Answer is:
Convection current
Please do have a great rest of your day!
The cycle that powers the ocean currents, weather, and tectonic plates it called convection current. The correct option is d.
What is convection current?Convection is the spontaneous flow of a single or multiphase fluid caused by the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity.
Convection currents are generated by radioactive decay in the core as heat rises and falls within the mantle. The plates are moved by convection currents.
Plates move apart where convection currents diverge near the Earth's crust. Plates move towards each other where convection currents converge.
Convection currents propel Earth's rigid tectonic plates through the planet's fluid molten mantle.
Tectonic plates move away from each other in places where convection currents rise up towards the crust's surface, a process known as seafloor spreading.
Thus, the correct option is d.

Suppose a scientist developed a hypothesis stating that a certain substance slowed down the growth of chili pepper plants. Briefly describe a controlled experiment
the scientist could conduct to test the hypothesis. Identify the controlled variables, the independent variable(s), and the dependent variable(s).
Answer:
The experiment consists of three different treatments:
1- Fifty (50) chili pepper plants treated with the substance X suspected to slow down the growth
2- Fifty (50) no treated chili pepper plants that grown in normal conditions
3- Fifty (50) chili pepper plants treated with a substance known to slow down the growth (positive control)
Dependent variable: plant growth
Independent variable: the amount of substance x (suspected to slow down plant growth)
Explanation:
The dependent variable is the variable that is being measured, while the independent variable isn't changed by the other variables in the experiment. In this case, the question is how chili pepper plants grow in response to the substance x, which is suspected to slow down the plant growth. During the experimentation, the plant growth will represent the dependent variable being analyzed. On the other hand, chili pepper growth will be in response to changes in the amount of substance x the plants receive, therefore being the independent variable.
Hypothesis development for substance.
A hypothesis is a temporary or tentative arrangement or explanation that is made for the experiment on the basis of an assumption. The experiments highlight the development of certain substances that slowed down to the growth of the chili pepper plans.
Thus the answer is slow growth, normal growth, and positive fast growth.
The assumed experiment consists of 3 treatments. As the first (50) chili pepper plants treated with substance X tend to slow down the growth. The second plant shows a grown in normal conditions. The 3rd plant sows the slow down the growth (positive control).Thus the dependent variable is then planted growth and the independent variable is substance X.Learn more about the scientist's development.

Which principle states that two species in the same habitat cannot have the same niche?
niche exclusion principle
competitive exclusion principle
habitat exclusion principle
population exclusion principle
Answer:
competitive
Explanation:
example 1: two male bucks cannot inhabit the same habitat or area because one needs all the females or pride for itself so it chases away the others
The competitive exclusion principle explains that two species occupying the same niche cannot coexist in the long term since competition is created between them for resources.
What is the competitive exclusion principle?It is a phenomenon that refers to the competition that one species has with another and the dependence of one organism to develop in terms of the other organism.
In competitive exclusion, one species is displaced by another when their niches overlap and compete for the same resources.
Therefore, we can conclude that the competitive exclusion principle establishes that two species that have the same ecological needs cannot live together since they create competition between them for resources.

significance of sexual reproduction
please answer fast
Answer:
Sexual reproduction is the process in which male and female gamete fuse to form zygote through a process called fertilization and it is important for plants as it provides variation to the progeny that helps in the better survival and help it to gain its own uniqueness within the species and remove the unwanted genes and lower the risk of getting a disease
Answer:
Sexual reproduction leads to variation which provides protection as different organisms will be more prone to different things
