What are invasive species?
A) Native species that have no predators.
B) Nonnative species that are superior competitors.
C) Nonnative species that do not survive.
D) Native species that prey on nonnative species.
Answer:
B
Explanation:
Answer:
B.
Explanation:
Invasive species imply that the species are not from the location that you are studying, so we can immediately eliminate A and D, as they mention native species (species that already live in the area). From this, we have B and C, and nonnative species do not become invasive if they die easily. So, we can eliminate C, leaving us with B as the answer. Nonnative species will most likely disrupt the ecosystem in the location that is being studied, so B makes the most sense. Hope this helps and please let me know if you still need help!

Some species of hares are brown most of the year, but change color to white in the winter. This allows them to blend in through the seasons.
Where are these organisms adapted to live?
deciduous forests
desert
tropical rain forests
savanna
Answer:
Snowshoe hares have an interesting adaptation that helps protect them against predators. Depending on the season, their fur can be a different color. During the winter, snowshoe hares are white, which helps them blend in with the snow. When the seasons change to spring and summer, snowshoe hares turn a reddish-brown.

HELPPPPPP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
Answer:
circle the brighter (yellow / red) areas, the are hotter, so we can expect more stars there.
the darker (blue / dark blue) areas are colder, do we expect less dense mattet/stars
since the areas are overall equal in energy density (note that the different color represent very little difference in temperature), we can expect a common origin, because regions of space so vastly apart couldn't possibly smooth out later, they would be to far apart.
Cual es la relacion entre la disponibilidad y el consumo de recursos renovables y no renovables entre los paises desarrollados y los paises en vias de desarrollo
Answer:
Diferente.
Explicación:
La relación entre la disponibilidad y el consumo de recursos renovables y no renovables entre países desarrollados y en desarrollo es diferente debido a la presencia de tecnología que permite a los países desarrollados utilizar sus recursos renovables y no renovables disponibles. Los países desarrollados están más avanzados que los países en desarrollo en el campo de la tecnología y también la economía, por lo que pueden utilizar recursos renovables en comparación con los recursos no renovables.
Which of the following is TRUE about the movement of earth's plates?
A. They do not move because they sit on a layer of solid rock
B. They move along with the layer of slightly softened rock below them
C. They move by floating on a layer of completely melted rock below them
D. They do not move until the solid rock layer beneath them temporarily melts and moves
Answer:
c
Explanation:
the tectonic plates or the crust of the earth sit on molten rock moving across the planet with causes the plates to move causing things like earthquakes and volcanos
Movement of Earth's plate can be due to many reasons and can cause many disasters. They move along with the layer of slightly softened rock below them
What is the 3 causes of this movement?Earth's plates move due to the intense heat in the Earth's core. This causes the movement of soften rock in the mantle layer.
It moves in a convection cell pattern that forms by rising of warm, cooling and then sinking down of material.
The Earth's plates move by floating on a layer of completely melted rock below them.
Thus, the correct option is B.

Answer the next five questions based on the following information. You are studying a particular type of spider and have identified four traits that follow simple mendelian genetics. The B gene governs body color and black body color is dominant to brown. The D gene governs whether or not the spider is poisonous, and poisonous is dominant to non-poisonous. The E gene governs eye color and black eyes are dominant to red eyes. The H gene governs hair type and hairy is dominant to hairless. Indicate your answer numerically not alphabetically. For instance, answer "2" not "two." For each answer that is not a whole number, give your answer as a fraction reduced to the lowest possible whole numbers. For instance, 3/9 would be reduced to 1/3.
How many different types of gametes can be formed by a spider that has the genotype BbDdEeHH?
If you chose a single gamete at random from a spider that has the genotype BbDdEeHh, what is the probability that the gamete would have the genotype BdEh?
You mate a BbDDEeHh spider with a BbDdEEHh spider. What is the probability that one randomly chosen offspring will have the genotype BbDdEEHH?
Answer:
a. 81/256.
b. 9/256.
b. 9 / 256.
Explanation:
The given traits in the question follow the Mendelian character. The cross between the body color where B is responsible for black color and b is responsible for brown color is as follows: Bb × Bb results in the 3/4 black color ( BB, Bb, Bb) and 1/4 brown color progeny (bb). The cross between the poisonous and nonpoisonous trait where D is responsible for poisonous trait and d is responsible for nonpoisonous is as follows: Dd × Dd results in the 3/4 poisonous trait (DD, Dd, Dd) and 1/4 nonpoisonous (dd). The cross between the eye color where E is responsible for black color and e is responsible for red color is as follows: Ee × Ee results in the 3/4 black color ( EE, Ee, Ee) and 1/4 red color progeny (ee). The cross between the hair trait where H is responsible for hairy and h is responsible for hairless is as follows: Hh × Hh results in the 3/4 hairy (HH, Hh, Hh) and 1/4 hairless (hh).
a. The cross between BbDdEeHh spider with a BbDdEeHh spider results in the 3/4black body, 3/4 black eyes, 3/4, hairy, and 3/4 poisonous progeny. Their probability is 3/4× 3/4× 3/4× 3/4 = 81/ 256.
b. The cross between BbDdEeHh spider with a BbDdEeHh spider results in the 3/4black body, 3/4 black eyes 1/4 hairless, and 1/4 nonpoisonous progeny. Their probability is 3/4× 3/4×1/4 3/4×1/4 = 9/256.
Thus, the answer is a. 81/256.

Why is cotyledon the biggest part of a seed?
Answer:
it is its outer cover of the seed
Answer:
The cotyledon is the largest part of the inside of the bean. Cotyledons are rich in proteins, starch, and fats. These stored nutrients are supplied to the seedling during germination. Like a chick embryo it has a yolk and a baby has an umbilical cord, a bean seed has a cotyledon to act as a source of food. At the top of the cotyledon is the epicotyl. Hence it is the biggest part of the seed .

Explanation:
The core threats to biodiversity are human population growth and unsustainable resource use. To date, the most significant causes of extinctions are habitat loss, introduction of exotic species, and overharvesting.
Answer:
Essay written by Applepi101
Biodiversity, and Humanity's Threat to Life.
A variation in genetics, species, and of course, an ecosystem level, biodiversity is the single most important thing we must preserve in order for the food chain to be in balance, and for one species to not overtake the scale. This is what makes Earth unique from every other planet on the solar system. Biodiversity provides everyone's needs for food and water, shelter and much more. The importance of this single word is astounding, not only because of the fact that it is needed to conserve humans, but all life on Earth. Biodiversity comes from two words. The first part, "Bio" meaning "life" and the second part, "diversity" meaning "variety". Combine the two, and you have the variety of life.
It is important to understand that biodiversity can be studied on a global scale, or microscopically, genetically, or environmentally. One example is genetic biodiversity in the cross-breeding of dogs, and environmental biodiversity is how diverse the ecosystems around us are. Preserving this is what humans have the task of while living on this beautiful planet. Although humans are widely consumer based, taking from the environment, the question is how much longer can the Earth sustain the rapid population increases while taking and modifying the Earth's environment?
Zooming in on our oceans, which cover over 70 percent of the earth's surface, they are becoming increasingly polluted and threatened each year, with climate change, fishing, commercial agriculture, pollution, and oil spills. Studies show that in 2050, there will be more plastic in the ocean than fish. In the oceans, coral reefs are the most biologically diverse ecosystem in the world, seeing that they have a number of fish communities to tend to. But our reefs are dying, which means less fish, which means less animals that eat the fish, like birds, and less animals that eat the birds, and so on, which I see as a ripple effect, one drop on the pond shakes the whole pond, the whole food chain, the whole scale, but not as much humans.
At the same time, large parts of the Amazon are being cut down and burnt. Tree clearing has cut down the forest by 15 precent already. In Brazil, which has half the forest, 19 percent has disappeared. Those number are just numbers though, but when we have no trees to look at, no flowers to smell, no grass to play in, it will be too late. Many have warned that at one point, the rainforest that contains over 3 million known species, will turn into nothing but a dry scrubland, and we don't have a clue when it will reach it's tipping point.
How can we help? Reducing, reusing, and recycling is just the beginning, started climate strikes, campaigns, and protests is a great way to get started. Volunteering for non-profits that are dedicated to taking young interns to help weed, garden, and grow plants is another effective way. The future depends on us, starts with us, and it is our responsibility to commit ourselves to making sure that we should not need a list to keep track of endangered or extinct species, and we must act now.
Hope this helps!!
