What do you know about ecosystems?

An ecosystem is a community of living things in a habitat that are in conjuction with the ninliving things in tehri habitat. The abiotic and biotic factros living together in a habitat in harmony that are all linked together by biochemical cycles and energy flows.

What living things do you think we would find in a rainforest ecosystem? What might those living things need to grow?

Living things that would be found in a rainforest ecosytem include the animals liek jaguars, spider monkeys, tapirs, camians, sloths, harpy eagles, mosquitos, ants, clouded lepord and amur leporad, apes liek chimpanzees and organguatans, tigers, brids of paradise, gorillas, elephants, frogs, bats, katydids, and so many more! Plants include pitcher plants, orchids, venus fly trap and otehr carnivorous plants, Açai Palm, rubber trees, various palm tree species, vines, bamboo, banana trees, strangler figs, giant red cedar, and many other flower tree, grasses, planst, bushes, fruit, vines, and otehr vegetation species. These living thinsg need to grow fruit, in size, in numbers, and many ways the rainforest.

What living things do you think we would find in a desert ecosystem? What might those living things need to grow?

Cati, succulents, tarantuals, scorpians, gila monster, cactus blossoms, sandwinders, dry grasses, coyotes, jackals, dingos, fennec foxes, vultures, gazelle, snakes and vipers, lizards, (remeber the artic ecosytems are deserts too! ) penguins, polar bears, seals, killer whales, lemmings, elk, walrus, beluga whales and narwhal, and so many more! these living things need to grow their fight and defense system features like the narwal's horn or walrus's tusks.

What living things do you think we would find in a savanna ecosystem? What might those living things need to grow?

In a savanna many things live here, porcupines, acacia trees, cheetahs, lions, lepords, hyeans, zebras, elephants, baboons, giraffes, rhinoceros, crocodiles, hippopotamus, termites, ostriches, ardvarks, anteaters,snakes, boa constrictors, kangaroos, scorpions, tartantuals, buffalo, baobob, scutch grass, and many more. These living things need to grow in their size to survive and grow in their knowledge of survival for life.

What living things do you think we would find in a coral reef ecosystem? What might those living things need to grow?

In a coral reef system you would find numerous shark species, coral, kelp, seaweed, sponges, algae, sea urchins, dolphins, sea turtles, seahorses, clownfish, starfish, jellyfish, mnay many species of fish, lobster, shrimp, crabs, snails, octopuses, rays, clams, worms, eels, manatees, and so many more. These plants need to grow to create ecosyetems and to create dissolved oxygen. Coral reefs need to grow to keep the habitat alive and going, to also fight the dwindiling reef numbers.

A woman with Liddle syndrome has a child with a normal male. what is the probability that their child will have the syndrome?

lesantik [10]

Answer:

An autosomal dominant gene is one that occurs on an autosomal (non-sex determining) chromosome. As it is dominant, the phenotype it gives will be expressed even if the gene is heterozygous.

The chances of an autosomal dominant disorder being inherited are 50% if one parent is heterozygous (NL) for the mutant gene and the other is homozygous for the normal (NN), or 'wild-type', gene. This is because the offspring will always inherit a normal gene from the parent carrying the wild-type genes, and will have a 50% chance of inheriting the mutant gene from the other parent. If the mutant gene is inherited, the offspring will be heterozygous for the mutant gene, and will suffer from the disorder. If the parent with the disorder is homozygous for the gene, the offspring produced from mating with an unaffected parent will always have the disorder.

Which of the following is TRUE?

Umnica [9.8K]

Answer:

a. Glucagon is released by the beta cells of the pancreatic islets of Langerhans.

Explanation:

When the body is fasting, the pancreas releases glucagon so that your body can produce glucose. Glucagon is a protein hormone made and secreted by alpha cells from pancreatic islets (or islets of Langerhans).

The islets of Langerhans are a special group of cells in the pancreas that produce not only glucagon, but also insulin. These substances act as important regulators of sugar metabolism.

In dogs, wire hair is due to a dominant gene (W), smooth hair id due to its recessive allele.a. If a homozygous wire-haired dog

Vsevolod [243]

Answer:

a) All the offspring produced would be a heterozygous in the first generation (F1 generation) with genotype: Ww, Ww, Ww, and Ww. Since wire hair is dominant, all would be wired haired.

b) In the F2 (second generation), we breed the heterozygous offspring from the F1 generation together (Ww x Ww). This will produce 3:1 ratio of dominant:recessive phenotypes having 3/4 of the offspring wire-haired (1/4 WW homozygotes and 1/2 Ww heterozygotes) and 1/4 will be smooth-haired (ww). Also the genotype would have the ratio 1:2:1 (i.e 1 homozygote WW, 2 heterozygote Ww and 1 smooth hair)

c) the chances of producing a smooth-haired pup is 1/4, and the chances of producing a wire-haired pup are 3/4.

d) Therefore, 1/2 of the offspring will have the genotype Ww and be wire-haired, and 1/2 of the offspring will be ww and be smooth-haired. Also the phenotype ratio is 1:1 (1/2 is heterozygote wired hair and 1/2 is smoth haired)

Explanation:

Since the wire hair is the dominant gene (W) and smooth hair (w) is the recessive allele

a) If a homozygous wire-haired dog is mated with a smooth-haired dog, All the offspring produced would be a heterozygous in the first generation (F1 generation) with genotype: Ww, Ww, Ww, and Ww. Since wire hair is dominant, all would be wired haired.

c) If two wire-haired dogs produce a smooth-haired pup, that means that both parents must be heterozygotes (Ww) having a pair of dominant W allele and recessive w allele to pass on to the offspring. Therefore, if these two dogs were to mate again (Ww x Ww), the chances of producing a smooth-haired pup is 1/4, and the chances of producing a wire-haired pup are 3/4.

d) If the mother of the wire-haired male was smooth-haired, that means that the recessive allele w had been passed on to the male making the male a heterozygote (Ww). When this male mates with a smooth-haired female (ww), the cross is Ww x ww. Therefore, 1/2 of the offspring will have the genotype Ww and be wire-haired, and 1/2 of the offspring will be ww and be smooth-haired. Also the phenotype ratio is 1:1 (1/2 is heterozygote wired hair and 1/2 is smoth haired)

Which renewable resource is not safe for the environment and why?

Karo-lina-s [1.5K]

Answer: Biomass

Biomass produces gas or many sorts of waste products which are mostly used in burning and cooking. It is plant or animal material used as fuel to produce electricity or heat. Examples are wood, energy crops, and waste from forests, yards, or farms.

But the reason why it can be harmful is because biomass can produce gases like methane. Methane is a greenhouse gas which can harm the environment and reduce the ozone layer that stops harmful UV light from reaching the earth atmosphere.
