Answer:

In Austrailia there is the highest rate of skin cancer because there is so much sunlight and most austalians have the wrong skin type for thier environment meaning people with pale skin get burnt more easily

Explanation:

Australia has a high rate of skin cancer because there's something different about the sunlight in Australia, and most people in Australia have skin that is easily damaged by light from the sun. Light carries energy that can make materials change. Therefore, Australia has a high rate of skin cancer because the ozone layer is damaged by the energy carried from the UV Light, being absorbed by the ozone and damaging allowing that light to transmit through and damage the genetic material of those individuals with lower levels of melanin.

Answer: Importance of replication in experiments

Explanation: Getting the same result when an experiment is repeated is called replication. ... Replication is important in science so scientists can “check their work.” The result of an investigation is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.

Answer:

True

Explanation:

The process of photosynthesis converts light energy to stored chemical energy by converting carbon dioxide plus water into sugars plus released oxygen.

[tex]\bf{\underline{\underline{PHOTOSYNTHESIS }} }[/tex]

Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the plant to survive.Carbon dioxide, water and light are all needed for photosynthesis to take place.Photosynthesis happens in the leaves of a plant.

Answer:

no, of course not

Would you use drugs to gain a competitive advantage in sports? No, its against the rules and also unethical. It's not healthy. You've seen Jurassic Park right? It would lead to ruin.

Answer:

Antigens are secreted by the endocrine system

Explanation:

The main job of the innate immune system is to fight harmful substances and germs that enter the body, for instance through the skin or digestive system. The adaptive (specific) immune system makes antibodies and uses them to specifically fight certain germs that the body has previously come into contact with

Answer:

decomposers

Explanation:

Answer:

decomposer

Explanation:

Fungi and bacteria are the most common decomposers.

Answer:

C. Y

Explanation:

The point that the kinetic energy increasing and its potential energy decreasing is Oz.

To calculate the kinetic energy of an object with mass “m” and speed “v”, we must apply the formula Ec = mv²/2, where: Ec – kinetic in joules; m – mass in kg; v – speed in m/s.

Gravitational potential energy that depends on the vertical position and mass of an object.

With this information, we can conclude that The point at which the kinetic energy increases and its potential energy decreases is Oz.

Answer:

Each time lizards colonized an island, they evolved into many of the same forms. .Other lizards adapted to life among the thin branches lower down on the trees, evolving short legs that help them hug their narrow perches. Still other lizards adapted to living in grass and shrubs, evolving long tails and slender trunks.Lizards are low on the food chain. Providing protection from their natural predators ensures their continued existence. Plant bushy perennials, create a rock or brush pile or use man-made items like stacks of bricks or pipes.

Answer:

The correct answer is - 1. a metal hammer

4. the metal frame of your chair

6. the screws and nails that hold your desk together.

Explanation:

Bar magnets are rectangular objects made up of ferromagnetic objects or substances and must carry the north and south pole ends. These objects show ferromagnetism and attract any ferromagnetic metal such as iron, steel  or ferromagnetic composite.

In the case of the same ends, for instance, the north-north pole of two magnets repulse and opposite attract to one another. From the given options the correct answer is a metal hammer, the metal frame of chair and screws and nails that hold the desk.

Answer:

Anaphase.

Explanation:

You can see the separation happening. This is anaphase.

Hope this is correct, good luck on your studies.

Answer:

C. The green allele is recessive to the yellow allele

Explanation:

Complete dominance occurs when one gene variant or allele referred to as the 'dominant allele' completely masks the expression of another allele referred to as the 'recessive allele' in heterozygous individuals, i.e., in individuals carrying one copy of the dominant allele and one copy of the recessive allele for a particular locus/gene (whereas homo-zygous individuals carry the same alleles for a given locus/gene). Mendel crossed pure lines of pea plants, i.e., homo-zygous lines for different traits such as seed color (yellow and green) and seed shape (round and wrinkled). In this case, the parental cross was YY x yy, where the 'Y' allele is dominant and encodes for yellow seed color, and the 'y' allele is recessive and encodes for green seed color. From this cross, Mendel obtained a hybrid F1 (i.e., all progeny was heterozygous with genotype Yy). An expected 3:1 ratio as observed in this case (6,022 yellow and 2,001 green seed >> 3:1 ratio) is characteristic of the progeny that results from mating between F1 heterozygous parents, where each parent has one dominant allele and one recessive allele, i.e., F1 parental cross: Yy x Yy >> F2: 1/4 YY (yellow color); 1/2 Yy (yellow color); 1/4 (green color) >> 3:1 ratio of yellow to green seeds.

Answer:

Presence of thorn stems, invasive nature and strong scent of of multi rose plant.

Explanation:

The presence of thorn stems, invasive nature and strong scent of of multi rose plant are the specialized structures found in multiflora rose support its reproduction and spreading and dispersal throughout ecosystems in the United States. The presence of thorn stems prevent animals to feed on the multi rose plant while on the other hand, strong scent of of multi rose flower attract pollinators that increase its pollination and increase occur in its population.

Explanation:

Have a nice day :)

Answer:

please tell me you know, my hands are literally shaking at how easy this question is

Explanation:

the answer is photosynthesis is a way for plants to make oxygen

still not enough information? they convert carbon-dioxide and water into oxygen and sugar, so they eat the sugar making their own food, put plants are living if they eat sugar. so they also have cellular respiration from mitochindria (photosynthesis is from chloroplasts and chrolophyll inside the chloroplast) and plants BREATH OUT SOME CARBON-DIOXIDE and produce more Oxygen than carbon-dioxide, thus providing the earth with Oxygen
