This is the question I need help with.

Explanation:

Hey there!

Your answer is option B.

Reason:

Base are the substance that produces hydroxyl ion dissolving in water.

Option A(true): The pH value of base is always greater than 7.

Option B (false): A base is considered as alkaline if it dissolves in water only otherwise they are not alkaline.

Option C (true): A base always has few hydrogen ions in it.

Option D(true) : A base has also few hydroxide ions.

Hope it helps!

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!

The best statement that describes the conclusion of the given scenario, is that parent can pass on only one factor for each trait to its offspring. The correct option is A.

Gregor Mendel proposed the law of inheritance after seven years of research on pea plants.

Mendel's inheritance laws encompass the laws of dominance, segregation, and independent assortment.

In this, the parent can pass on only one factor for each trait to its future offspring.

Thus, the correct option is A.

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.

Answer:

The correct answer is - mitochondria lack ribosomes like prokaryotes.

Explanation:

The Endosymbiotic Theory says that mitochondria and chloroplast in eukaryotic cells are developed by the once aerobic bacteria that were engulfed by a large anaerobic bacteria.

This theory suggests the origin of eukaryotic cells. Various evidence exists such as mitochondria and chloroplasts contain their own circular DNA like prokaryotic cells and mitochondria and chloroplasts have 70S ribosomes like prokaryotes have.

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.

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.

Explanation:

C) How will the rise in sea level affect tourism in coastal areas?

D) At what rate is the sea level expected to rise in the next 100 years?

E) Which coastal towns face the greatest risk of flooding because of the rising sea level?

Above are the questions about the present data that would help coastal communities plan for a natural disaster now and in the future in order to prevent floods and other natural disasters. The main reason for this rising of  sea level is the release of huge amount carbondioxide gas in the atmosphere that causes global warming which leads to melting of glaciers and the sea level rises.

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!!
