B = S phase ( Growth and DNA Synthesis)

C = G2 phase (Growth and final preparations for division)

D = Mitotic phase (Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis)

Answer:

Rocks

Explanation:

The geosphere includes the rocks and minerals on Earth – from the molten rock and heavy metals in the deep interior of the planet to the sand on beaches and peaks of mountains. The geosphere also includes the non-living parts of soils and the skeletons of animals that may become fossilized over geologic time.

The feature of Earth that is a part of geosphere is rocks. The correct option is C.

There are several contradictory definitions of geosphere. It can be used to refer to the lithosphere, hydrosphere, cryosphere, and atmosphere as a whole.

The geosphere's various collectives can exchange various mass and/or energy fluxes.

The geosphere includes all of Earth's rocks, from partially melted rock beneath the crust to ancient, towering mountains to grains of sand on a beach.

The geosphere and hydrosphere both provide habitat for the biosphere, which is a global ecosystem that includes all living things on Earth.

The Geosphere is in charge of the distribution of rocks, minerals, and soils. It also manages the difficult natural hazards that shape the land and have an impact on our lives.

Thus, the correct option is C.

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 .

urinary bladder

Explanation:

In biology, there are five levels of organization namely: cell, tissue, organ, system, and organism. A collection of one forms the other, starting from the smallest CELLS. The human excretory system consists of organs that make it up.

Kidney is one of the organs that make up the excretory system. According to this question, the urinary bladder is also an ORGAN, which means that the kidney and bladder as ORGANS are functioning at the same level of organization in the excretory system.

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 potato can make you feel at home in any part of the world. According to the International Potato Center, the potato is the third most grown crop in the world, with more than 300 million metric tons produced annually. The United Nations declared 2008 as the International Year of the Potato because of its importance in feeding the poor and hungry. If not deep-fried and loaded with butter or cheese, potatoes have a lot to offer nutritionally, and they are easy to digest as well.

Salivary amylase, an enzyme secreted with the saliva, acts at the long polysaccharide units that make up starch, to shape disaccharides known as maltose. The action of salivary amylase keeps until the potato reaches the belly.

The belly empties the chyme containing the damaged egg pieces into the small intestine, where the general public of protein digestion occurs. The pancreas secretes digestive juice that consists of extra enzymes that in addition smash down the protein fragments.

Digestive enzymes play a key position in breaking down the meals you eat. those proteins accelerate chemical reactions that turn vitamins into substances that your digestive tract can take in. Your saliva has digestive enzymes in it. Some of your organs, consisting of your pancreas, gallbladder, and liver, additionally release them.

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!!

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:

It is expected that each parent is homo-zygous for each trait (i.e., one parent has genotype AA and the other parent has genotype aa)

Explanation:

An F1 hybrid is the first filial generation of the progeny of distinctly different parental types. In this case, it is expected that each parent is homo-zygous for each trait, thereby 100% of all offspring will have genotype Aa (i.e., parental cross: AA x aa >> F1 = 100% Aa). On the other hand, in a cross where one parent is heterozygous for the trait (Aa) and the other parent is homo-zygous (either AA or aa), only 50% of all offspring will have genotype Aa.
