When looking at the cell membrane, where are the lipid heads located?

Answers

Answer:

The cell membrane consists of two adjacent layers of phospholipids, which form a bilayer. The fatty acid tails of phospholipids face inside, away from water, whereas the phosphate heads face the outward aqueous side.

The cell membrane consists of two adjacent layers of phospholipids, which form a bilayer. The fatty acid tails of phospholipids face inside, away from water, whereas the phosphate heads face the outward aqueous side.

What is cell membrane?

The cell membrane is a biological membrane that separates and protects the interior of all cells from the outside environment.

Moreover, the cell membrane, also called the plasma membrane, is found in all cells and separates the interior of the cell from the outside environment. The cell membrane consists of a lipid bilayer that is semipermeable. The cell membrane regulates the transport of materials entering and exiting the cell.

Hence, cellular membranes — including plasma membranes and internal membranes — are made of glycerophospholipids, molecules composed of glycerol, a phosphate group, and two fatty acid chains.

Base your answer on the information below. A decade after the Exxon Valdez oil tanker spilled millions of gallons of crude [oil] off Prince William Sound in Alaska, most of the fish and wildlife species that were injured have not fully recovered. Only two out of the 28 species, the river otter and the bald eagle, listed as being injured from the 1989 spill are considered to be recovered said a new report, which was released by a coalition of federal and Alaska agencies working to help restore the oil spill region. Eight species are considered to have made little or no progress toward recovery since the spill, including killer whales, harbor seals, and common loons [a type of bird]. Several other species, including sea otters and Pacific herring, have made significant progress toward recovery, but are still not at levels seen before the accident the report said. More than 10.8 million gallons of crude oil spilled into the water when the tanker Exxon Valdez ran aground 25 miles south of Valdez on March 24, 1989. The spill killed an estimated 250,000 seabirds, 2,800 sea otters, 300 harbor seals, 250 bald eagles, and up to 22 killer whales. Billions of salmon and herring eggs, as well as tidal plants and animals, were also smothered in oil. Reuters The oil spilled by the Exxon Valdez tanker is an example of ______________.

Answers

Answer:

Explanation: The Exxon Valdez oil spill was a manmade disaster that occurred when Exxon Valdez, an oil tanker owned by the Exxon Shipping Company, spilled 11 million gallons of crude oil into Alaska’s Prince William Sound on March 24, 1989. It was the worst oil spill in U.S. history until the Deepwater Horizon oil spill in 2010. The Exxon Valdez oil slick covered 1,300 miles of coastline and killed hundreds of thousands of seabirds, otters, seals and whales. Nearly 30 years later, pockets of crude oil remain in some locations. After the spill, Exxon Valdez returned to service under a different name, operating for more than two decades as an oil tanker and ore carrier.

On the evening of March 23, 1989, Exxon Valdez left the port of Valdez, Alaska, bound for Long Beach, California, with 53 million gallons of Prudhoe Bay crude oil onboard.

At four minutes after midnight on March 24, the ship struck Bligh Reef, a well-known navigation hazard in Alaska’s Prince William Sound.

The impact of the collision tore open the ship’s hull, causing some 11 million gallons of crude oil to spill into the water.

At the time, it was the largest single oil spill in U.S. waters. Initial attempts to contain the oil failed, and in the months that followed, the oil slick spread, eventually covering about 1,300 miles of coastline.

Investigators later learned that Joseph Hazelwood, the captain of Exxon Valdez, had been drinking at the time and had allowed an unlicensed third mate to steer the massive ship.

Most biologists say no they are not

Answer: As for now, no, it is not clarified but most biologists say no. Because viruses don’t grow, aren’t made out of cells, can’t stay in a stable state, nor can they make their own energy. Most living things do these things, so the are classified as nonliving.

Which of the following suggests what happens when a mutation occurs in an organism? Select one:
Genes begin to appear in different individuals of the population all at once.
The organism develops new traits as a result of using a particular body part.
New traits appear from changes in the instructions given to the cell by the DNA. Useless traits are removed from the organism due to the loss of nucleotides​

Answers

Answer:

New traits appear from changes to the DNA..

Explanation:

A mutation is when DNA is changed or altered in some way, causing it to tell the cells to do something different from what they usually do such as growing a body part a certain way, or making skin regenerate a certain way. some mutations are specific to one individual person or thing, other mutations are passed down through generations and become a new normal for the species. new diseases such as viruses are often caused by the virus mutating...this is how we have so many different strains of the flu...

There are the same amount of carbon atoms on Earth now as there were in the past, but there are more in the atmosphere ever before. What explanation do you have for this?

Answers

The global average atmospheric carbon dioxide in 2019 was 409.8 parts per million (ppm for short), with a range of uncertainty of plus or minus 0.1 ppm. Carbon dioxide levels today are higher than at any point in at least the past 800,000 years.The carbon cycle describes the process in which carbon atoms continually travel from the atmosphere to the Earth and then back into the atmosphere. Since our planet and its atmosphere form a closed environment, the amount of carbon in this system does not change.

if humans began hunting and driving the great barracuda to extinction how would this affect the ecosystem (answer should discuss biodiversity, food webs, and food chains)

Answers

Answer:

Generally considered to be the tertiary consumers (top level of the food pyrmaid), barracuda feed on an array of preys including grunts, groupers, snappers, small tunas, mullets, killifishes, herrings, and anchovies. By feeding on these marine organisms, barracuda prevent them from increasing in number.

Now let's barracuda's number starts decreasing due to hunting and other reasons. This will result in other primary and secondary consumers to increase in population. An increase in the number of primary and secondary consumers in the food chain will result in a decreasing number of plants, i.e. the number of producers decreases. Hence, this will negatively affect other connected food chains in the marine food web.

How does survivorship relate to an individual's fitness?

Answers

Answer:

Ecologists use survivorship curves to visualize how the number of individuals in a population drops off with time. In order to measure a population, ecologists identify a cohort, which is a group of individuals of the same species, in the same population, born at the same time.

The higher the survivorship of an organism, the higher the fitness of the organism

What is survivorship ?

The term survivorship refers to the ability of an organism to live long in its habitat and reproduce. This is related to the fitness of an organism which is its ability to survive to the next generation.

Hence, the higher the survivorship of an organism, the higher the fitness of the organism and vice versa.

The chart below demonstrates the number of genetic differences between 9 species. Which two species are least closely related to each other according to the information provided?

Answers

Hi. You did not submit the chart to which this question refers, which makes it impossible for it to be answered. However, I will try to help you as best I can.

Generally speaking, we can state that the two species that are less genetically related are those that present more genetic differences between them. This is because the number of genetic differences is greater in species that have no genetic relationship, or that have a very weak genetic relationship.

In this case, to answer this question, you need to assess which two species, shown on the chart, have the greatest number of genetic differences between them.
