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.

In the small intestine, where are fatty acids and monoglycerides absorbed?

Inessa [10]

Answer:B

Explanation:when fat are ingested,it has to be emulsified and broken down into monoglycerides,fatty acids.these molecules have a polar hydrophilic end and a non polar hydrophobic end .the fatty acid and monoglycerides that enter the cells of the mucosa are formed back into large tryglycerides molecules ,which then forms chylomicros, which are water soluble.they then pass into the lacteal vessels from where there are Transported to meet the body's needs

I'll give 100 points & a brainliest for whom ever can answer these properly. This is for a grade 11 semester research paper

anygoal [31]

I kept a record of the sources with the extracted information. I have the links if you would like them.

Hydro-international article: Benthos, Inc.

Benthos was founded by Samuel O. Raymond.

He created an innovative company in marine technology which has positively impacted the field for over four decades.

It manufactures a variety of oceanographic equipment, including flotation devices; hydrophones for locating mining sites, tracking boats, and research for marine biology; and modems, which are used to communicate information wirelessly underwater.

For much of the company's lifetime, it supplied underwater equipment to the military, the government, and for research.

Smithsonian Magazine: 14 fun facts about marine bristle worms

Polychaete worms are a diverse class of animals with at least 10,000 species.

They are characterized by a head and a tail, and a pair of bristled "legs", called parapodia, for each segment of their body. They are typically bioluminescent, meaning they have the natural ability to glow.

Due to their effective adaptation, they can live in any marine habitat (including coral reefs, hydrothermal vents, or simply out in the open ocean) and have survived the five mass extinctions since 500 million years ago.

National Ocean Service: What is a bivalve mollusk?

Bivalves are mollusks with a two-part hinged shell to cover a soft invertebrate. They breathe and eat using gills.

Their organ, the mantle, produces calcium carbonate which causes the shell to grow with the organism.

They have important roles of being prey for predators, filtering water, and acting as a habitat in aquatic ecosystems.

These mollusks can live in any of the five oceans, whether it be the frozen Arctic or the hydrothermal vents in the Pacific.

There are over 9000 species.

Marine Education Society of Australasia: Echinoderms

Echinoderms are characterized by radial symmetry, having multiple of five arms, a calcium carbonate shell, and an outer layer of skin that maintains the skeleton.

They are found on the sea floor and include starfish, sea cucumbers and sea urchins.

They have the ability to hunt prey larger than their mouths due to their ability to eat from their stomachs. They detect food through a senstitivty to chemicals, although they lack any brains.

There are over 7000 species.

Thoughtco: Sea Squirts

Sea Squirts, scientifically tunicates or ascidans, are a class in the animal kingdom with over 2000 species.

They were given this name for their ability to contract and squirt water.

They do this using the inhalant and exhalant siphons, which are also used for eating and excreting waste.

They live in subtidal locations while attached to shells, rocks, piers and boat hulls.

Sea Squirts may live in colonies or individually. Colonies are created when they reproduce by budding, or when a new animal grows off of the original.

National Geographic.com: Sea Anemones

Sea anemones are an invertebrate which have stinging and venom-filled tentacles, called polyps, to hunt passing fish.

They tentacles surround a central mouth and inject a paralyzing substance into its prey, before guiding them into the mouth.

Apart from hunting, they also eat leftovers from clownfish, who are immune to the anemone because they are covered with a mucus and live within the polyps.

They live attached to rocks on the seafloor and coral reefs, usually in tropical waters.

There are over 1000 species.

Conclusions or Summary:

The marine technology company Benthos led to the discovery or further information about these animals because it provided equipment to researchers.

All of these organisms are animals and diverse with thousands of species in each of these common names.

They are adaptive and can generally live and thrive in a variety of habitats, whether the difference be in surface material or climate.

28) The graph below shows how the activity of an enzyme changes at different temperatures.

puteri [66]

Answer:

d) The enzyme changes shape and can no longer speed up the reaction

Explanation:

Enzymes aare protein in nature therefore sensitive to changes in temperature. Most enzymes have an optimum temperature ranging from 35-40°c. As the temperature increases, optimum temperature is reached where the rate of reaction is maximum. Temperatures above 40-63°c denatures the enzymes making them non effective thus the reaction decreases sharply.

choli [55]

Answer: In ecosystems, matter and energy are transferred from one form to another. Matter refers to all of the living and nonliving things in that environment. Nutrients and living matter are passed from producers to consumers, then broken down by decomposers. Decomposers break down dead plant and animal matter.
