Biological evolution is defined as: change in the properties of organisms over the course of development.
Evolution is the phenomenon of change in the genotype or phenotype of an organism over the course of time. The result of evolution can be a new species or the same species with new characteristics. Evolution makes the organisms survive better in the changing environment.
Development is the progressive growth of an organism. The change in shape, size, and functions of the organism determine its growth. Change in mass is not a criteria for development. The change of a zygote into a completely mature organism can be considered as an example of development.

The rate of CO₂ concentration increase ( ppm / yr ) from 1975 to 2012:
1971-1980 = 1.35 ( ppm / yr )
1981-1990 = 1.56 ( ppm / yr )

2001- 2012 = 2.04 ( ppm / yr )
Carbon dioxide concentrations are rising typically due to the fossil fuels that human beings are burning for strength. Fossil fuels like coal and oil include carbon that vegetation pulled out of the atmosphere through photosynthesis over many tens of millions of years; we are returning that carbon to the environment in only a few hundred.
Due to the fact the northern hemisphere consists of much extra land than the southern hemisphere – which is more often than not covered with the aid of ocean – the quantity of carbon dioxide inside the atmosphere will increase universal all through the northern iciness.

if you were designing a policy to protect islands from invasive species what types of islands would you choose to focus on and why
If i was designing a policy to protect islands from invasive species, the types of islands which would be focused on is Pacific island due to the absence of natural competitors which control the ecosystem.
What are Invasive species?This is referred to organisms who aren't indigenous to an area and end up becoming overpopulated in the given area.This therefore leads to the organisms causing economic and environmental harm to the new area.
This is usually caused when there is an absence of natural predators or competitors which control the ecosystem in the area which is the reason why there is a high increase in population growth.

According to the law of ______________________________, the price of copper is directly related to the rate of its production.
According to the law of supply and demand, the price of copper is directly related to the rate of its production.
The quantity of a good supplied, or the amount owners or producers offer for sale, is said to increase as the market price increases and decreases as the price decreases according to the law of supply. In contrast, the law of demand (see demand) states that when a good's price increases, less of it is sought and vice versa.
A basic tenet of economics is that when there is more supply than demand for an item or service, prices decline. Prices typically increase when demand outpaces supply. When demand is constant, there is an inverse relationship between supply and prices of products and services.
The link between supply and demand is crucial because it helps to establish the costs and availability of the majority of goods and services in a given market. The interplay between supply and demand eventually balances out in accordance with the tenets of a market economy.

On the basis of the principle of complementary base pairing, you would expect the percentage of adenine in an individual’s DNA to be equal to the percentage of thymine.
What is complementary base pairing?The expression that denotes the complementary base pairing makes reference to the arrangement of nucleotides in the double helix of DNA.
In DNA, Adenine or A always pairs with Thymine or T (thereby the amount of A is equal to T), while Guanine or G always pairs with Cytosine or C (thereby the amount of G is equal to C).
Base complementarity is one of the most important rules in genetics and it is used to estimate nucleotide proportion, a process associated with gene expression in CpG islands.

A male stickleback fish attacks other males that invade its nesting territory (see Figure 51.2a ). Predict the likely pattern of dispersion for male sticklebacks, and explain your reasoning.
Male sticklebacks are thought to disperse uniformly, with antagonistic encounters preserving a largely constant distance between them.
Sticklebacks :
Sticklebacks are members of the fish family Gasterosteidae. They share ancestry with seahorses and pipefish. Small fish known as sticklebacks can be found in lakes, streams, brackish systems, and the ocean. Sticklebacks are less sensitive to salinity than the majority of other fishes, and they frequently coexist in fresh, brackish, and marine ecosystems.
Are sticklebacks edible ?Although sticklebacks aren't typically considered to be edible, they can supposedly be used to produce "a excellent and healthy fish-soup.
Size of sticklebacks :Sticklebacks are tiny, elongated fish that can grow up to 18 centimeters in length (7 inches). The family's members can be identified by a row of 2 to 16 spines on the back that are arranged in front of a dorsal fin with soft rays.

Explain how ice floating on the surface of a body of water affects the water in a way that is beneficial to the organisms in it.
ice floating on the surface of a body of water insulate the water in a way that the ice layer insulates the water below it by insulating the top of lakes and seas, allowing it to stay liquid, which allows the life within it to survive.
but sometimes it has negative impact on sea organism because When ice forms across the surface of a lake, it seals off the water from atmospheric oxygen exchange and blocks out much of the light that is necessary for aquatic plants and phytoplankton to produce oxygen within the lake. Throughout the winter oxygen levels in the lake slowly decline. so organism may face difficulties to survive .
If ice didn't float it would form at the bottom of a body of cold water rather than the top. The water would continue radiating heat away from its surface and so would get colder and colder until the water and everything in it had frozen solid from the bottom up. and organisms will die.

How are the functions of FSH and LH in females and males similar?
The similar main function of FSH and LH in females and males is to follow up the gonadal cell and release sex hormones.
The hormones FSH and LH are gonadotropin hormones orchestrated by the front portion of the pituitary organ. These hormones serve comparative capabilities in the male and female bodies.
The FSH hormone is demonstrated by stimulating the development of tissues that manage the development and sustenance of the gametic cells. The capability of LH in both sexes is to set off the blend of essential sex hormones (testosterone and estradiol).
The follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are gonadotropins that are delivered because of the feeling of the gonadotropin-releasing hormone (GnRH). These hormones have a comparative capability in the reproduction of the two females and males.
The prime function of FSH is to follow up on the gonadal cells and stimulate their development which thus capability to give sustenance to the creating gametic cells.
The function of LH is to improve the release of sex hormones from the gonadal cells (primarily estradiol in female bodies and testosterone in males); these hormones, thus, stimulate the course of gamete creation.
