13-22 Aquaculturists (people who farm marine resources, typically in semi-enclosed areas off the coast) have development methods of growing various invertebrates as food sources, such as clams, mussels, and oysters. Other widely consumed species, such as squid, have never been successfully grown in controlled marine environments, and so they remain wild caught. Why

Answers

Answer 1

Answer: There are several problems associated with handling of the squid.

Explanation:

Squid is a deep sea creature which becomes enormously big in size and difficult in handling in artificial water body or aquaculture.

It consumes and requires huge amount of food in the pre-larval stages typically phytoplankton and it becomes difficult to provide such food to them.

The maintenance of temperature, and salinity for the squid in aquaculture is difficult.

The sticky arms of the squid adhere to the surface of tub or human handler making it difficult to handle and can be poisonous to humans too.

In what order do species appear during primary and
secondary succession?

Answers

Answer:

here you go :)

Explanation:

Primary succession is one of two types of biological and ecological succession of plant life, occurring in an environment in which new substrate devoid of vegetation and other organisms usually lacking soil, such as a lava flow or area left from retreated glacier, is deposited. In other words, it is the gradual growth of an ecosystem over a longer period of time.

In the primary succession, species like algae, fungi, and lichens are preset. In the secondary succession, the pioneer species present, that already existed in the environment.

What are primary and secondary succession?

One of two types of biological and ecological succession of plant life. They are primary succession that takes place in environments where fresh substrate is deposited that is devoid of plants and other species that typically lack soil, such as lava flows or areas left behind from glaciers that have receded.  

In other words, it is the steady development of an ecosystem through time.

Thus, Algae, fungus, and lichen species are established during the primary succession. The pioneer species that were previously existing in the habitat are found in the secondary succession.

How do divisions in the geologic time scale differ from the way we organize time using a clock?

Answers

Explanation:

The Earth's geologic past is divided into hierarchical time periods. This hierarchy comprises eons, eras, times, epochs, and ages, from largest to smallest. The Cenozoic, Mesozoic, and Paleozoic Periods are the three main divisions of the Phanerozoic.

The geological timescale is the official earth clock and differs from the way we organize time using a clock, as the planet's time is too long for us to use measures of hours.

Geologic timescale

Planet Earth is about 4.5 billion years old. To better understand its history, scientists divide geologic time into five levels of classification, called chronostratigraphic units:

EonsErasPeriodsEpochsand ages.

Eons are large and indeterminate spans of time and are divided into four classifications:

Phanerozoic (last 542 million years)ProterozoicArcheanand Hadean.

Of them, only the Hadean is not divided into ages. The ages are characterized according to the different positions of continents, oceans and their living beings. Within the ages are divided in the periods. Epochs, in turn, are divisions within periods and are divided into ages. According to the researchers, we currently live in the Quaternary period of the Cenozoic era.

To get a rough idea of ​​how much the existence of the human being is a mere recent episode in Earth's geological time, we use some analogies. For example, if the entire history of the planet were summarized in the twenty-four hours of a day, the existence of humanity would have occurred in the last three seconds of that same day.

Understanding the dimension of geological time and its scales of measurement becomes a fascinating mental exercise to better understand the role of man in relation to this temporality and his role as heir of all the transformations that have taken place in terrestrial space throughout the geological ages.

Answer: Green plants and trees use photosynthesis to make food from sunlight, carbon dioxide and water in the atmosphere: It is their primary source of energy. The importance of photosynthesis in our life is the oxygen it produces. Without photosynthesis there would be little to no oxygen on the planet.

Explanation:

Increasing sea surface temperatures should...
Lower the amount of dissolved oxygen in the ocean, depriving many
invertebrate animals of oxygen necessary to live.
Lower the amount of sea ice in polar areas. This will warm the water,
decreasing the abundance of primary producers and the number of
organisms that eat these producers.
Increase the temperature difference between the upper and lower parts of
the ocean, making upwelling less likely to occur. This will decrease ocean
nutrient levels, affecting the number of primary producers.
Raise water temperatures above the tolerance limits for many aquatic
organisms in tropical areas, increasing stress on these species.

What do you mean by metabolism?

Metabolism is the set of life-sustaining chemical reactions in organisms. The three main purposes of metabolism are: the conversion of the energy in food to energy available to run cellular processes.

Moreover, it is the process by which the body changes food and drink into energy. During this process, calories in food and drinks mix with oxygen to make the energy the body needs. Even at rest, a body needs energy for all it does.

Hence, if your metabolism is "high" (or fast), you will burn more calories at rest and during activity. A high metabolism means you'll need to take in more calories to maintain your weight. That's one reason why some people can eat more than others without gaining weight.

Answers

Answer:

Uses hydrolases -lysosome

Uses the enzyme catalase- peroxisome

Is one of the main sites of fatty acid breakdown- peroxisome

Combines with endosomes to digest ingested matter- lysosome

Capable of converting hydrogen peroxide to water and oxygen- peroxisome

Destroys engulfed bacteria- lysosome

Main role is metabolism- both lysosome and peroxisome

Digestive interior is acidic- lysosome

Proteins are derived from the endoplasmic reticulum- Peroxisome

Explanation:

The lysosome is a membrane-bound organelle found within a cell whose main function is to ensure the break down of biological polymers, such as proteins and polysaccharides. It is comprised of enzymes that are degradative in nature that can degrade biological polymers such as proteins, nucleic acids, lipids, etc. They contain various types of hydrolytic enzymes such as proteases, nucleases, glycosidases, lipases, phospholipases, phosphatases, and sulfatase. These enzymes are acid hydrolases as they function in the acidic environment of the lysosome. Lysosomes are also used by the cell to destroy invading viruses and bacteria.

Peroxisomes are membrane-bound organelles found within the cytoplasm of a cell. They are derived from the edoplasmic reticulum. Peroxisomes are involved in lipid biosynthesis, for example, cholesterol and dolichol are synthesized in peroxisomes. Peroxisomes are also involved in the synthesis of bile acids from cholesterol.

Peroxisomes contain enzymes that oxidize fatty acids and amino acids. Peroxisomes also contain enzymes such as catalase that convert hydrogen peroxide to water and oxygen preventing oxidative damage by these reactive oxygen species.

The service box is an area on the court that 1 point the person serving must stand in. the ball must land in to be a playable serve. the person returning the serve must be standing in before a server can serve ​

Answers

Answer:

Both players on the serving doubles team have the opportunity to serve and score points until they commit a fault *(except for the first service sequence of each new game).

The first serve of each side-out is made from the right-hand court.

If a point is scored, the server switches sides and the server initiates the next serve from the left-hand court.

As subsequent points are scored, the server continues switching back and forth until a fault is committed and the first server loses the serve.

When the first server loses the serve the partner then serves from their correct side of the court (except for the first service sequence of the game*).

The second server continues serving until his team commits a fault and loses the serve to the opposing team.

Once the service goes to the opposition (at side out), the first serve is from the right-hand court and both players on that team have the opportunity to serve and score points until their team commits two faults.

In singles the server serves from the right-hand court when his or her score is even and from the left when the score is odd.
