what do you mean by bacteria?​

Answers

Answer:

Bacteria is a type of micro-organism and is also a prokaryote. These organisms can only be seen using a microscope. Some bacterias are harmful while some are helpful for human daily lives, such as probiotics, and are necessary for life. They have simple cell structures as there is no nucleus or membrane-bound organelles. Bacterias can be found in soil, water, plants, animals, etc. They can cause diseases such as Tuberculosis etc. Due to some diseases being caused by bacterias, doctors prescribe Antibiotics which has the ability to stop the activities in bacterial cell that causes it to lose its protective outer covering and completely stops it from multiplying.

Answer:

Bacteria are among the smallest living things. A single bacterium consists of just one cell, and is called a single-celled, or unicellular organism.

Even though it is just a single cell, it can carry out all seven life processes (movement, respiration, sensitivity, growth, reproduction, excretion and nutrition).

6. If the time period were extended to 6 hours, what would be the expected blood sugar level for
Person B?

Answers

According to the graph, the blood sugar level for person B is 130 mg/dL after 6 hours of eating meal.

The blood sugar level is highest just after eating the meal but with the passage of time, the concentration of blood sugar level decreases due to absorption by the body. One hour after eating the meal, the blood glucose level is slightly decreases but after 6 hours, the blood glucose level tends to very low due to more consumption of the body or storing by the body in different parts.

__plants important adaptation of the seed allowed plants to__
A. Non vascular, grow in underwater environments
OB. Angiosperm, attract pollinators
C. None of these
D. Gymnosperm, spread quickly across the land

Answers

Answer:

C

Explanation:

Non vascular plants reproduce by spores or other asexual means

Attraction of pollinators is not an adaption of the seed. In angiosperms the colorful petals attract pollinators.

adaptations of seeds is their ability to store food, be dormant for preservation. They do not adapt to spread across the land via Gymnosperms. seeds can spread around via animals who eat the fruit and move from place to place. Gymnosperms do not produce flowers, so they don't have fruits. Though wind may blow their seeds, it's still not an adaptation.

Gymnosperm plants important adaptation of the seed allowed plants to spread quickly across the land.

So, option D is correct option.

Non vascular plants reproduce by spores or other asexual means.Attraction of pollinators is not an adaption of the seed. In angiosperms the colorful petals attract pollinators.The seeds spread around via animals who eat the fruit and move from place to place. Gymnosperms do not produce flowers, so they don't have b.

what are the structural adaptation of whales and dolphins (compare them please)

Answers

Answer:

Whales and dolphins are mammals and have lungs instead of gills for breathing. They have blowholes at the tops of their heads that function like nostrils; they need to put their heads above water every so often to breathe. Both dolphins and whales have hair instead of scales, another quality that is specific to mammals. The animals have live births instead of laying eggs, and baby dolphins and whales nurse from their mothers. Whale and dolphin births take place near the surface of the water, so the young animals can easily take their first breath.

Both whales and dolphins rely on the sounds they make for survival, even though the sounds are utilized differently by each animal. For instance, whales make high-pitched groans and whistles to communicate with one another to warn against danger or navigate during migration

Answer:

COMPARISON AND CONTRAST OF WHALES AND DOLPHINS

Both dolphins and whales belong to the cetacean family and are marine animals that reside in the ocean. Some scientists even assert that dolphins are a type of whale, as the two animals have a number of shared characteristics. However, there are distinct differences between whales and dolphins as well that will teach you more about the physical appearance of these marine creatures and how they survive in their environment.

You are overseeing a paleontological expedition at the Grand Canyon to uncover fossils. You have one group working about 10 feet above the bottom of the canyon,
uncovering a cluster of Brachiopods You have a second group working about 300 feet above the bottom of the canyon, uncovering impressions from a variety of plants
such as fems and horsetails. While you are waiting for the exact age of the rock layers to be determined, what can you tell about the age of the fossils based on
where they are
A. You cannot determine anything yet.
B. They are all about the same age.
C. The plants must be older than the Brachiopods.
D. The Brachiopods must be older than the plante

Answers

Answer:

C

Explanation:

because the plants are farther down lol

Paleontology establishes the geological age of the organisms. Based on the height of the fossils discovered at the Grand Canyon, it can be concluded that plants were older than the Brachiopods. Thus, option C is correct.

What are fossils?

The dead remains and decaying materials of the plants and animals stored and preserved under the sediments and rock layers over a period of many years are said to be called fossils.

The fossils are evidence of the evolution as well are used to determine the geological age of the species based on their occurrence of them in the rock layers.

The fossils of plants like horsetails and ferns were found 300 ft above the Canyon while Brachiopods at 10 feet above Canyons that tell that plants were found earlier than the former species.

Therefore, option C. the plants existed prior to the Brachiopods.

Identy three advantages and three disadvantages of bioplastics

Answers

Explanation:

Advantages of bioplastics

1.Less oil is used to produce petrochemical (oil-based) plastics which pose a great risk to the environment.

2.The common bioplastics can be injection molded and shaped to take the same form as traditional thermoplastics. In some cases, the bioplastics are stronger and lighter, too, so they are not necessarily only suitable for very niche applications.

3.Bioplastics are more marketable, for example, their usage may improve the value-add of a product through a green marketing campaign. After all, studies have shown that ‘80% of European customers want to buy products with a minimal impact on the environment,’ so bioplastics may represent a useful argument for brands.

Disadvantages of bioplastics

1.First, bioplastics are generally NOT cost-competitive compared to their oil-based counterparts. They are generally two or three times more expensive than the major conventional plastics such as PE or PET, and their production is plagued by low yields and being expensive. This disadvantage should be less acute when manufacturing plants become larger and benefit from economies of scale. A good example is Braskem’s 200,000-tonne bio polyethylene plant (equivalent to about 20% of the world’s current bioplastics production).

2.There is a concern that bioplastics based on terrestrial crops could harm food supplies; however, new innovations using food waste could be helpful in this regard and the concerns would seem to be unfounded as: ‘Perhaps 300,000 hectares are used to grow the crops which the industry processes into plastics. For comparison, this is about 0.02% of the world’s total naturally irrigated area available for cultivation. Even if half the world’s plastics were made from crops grown on food land, the industry would only require 3% of the world’s cultivated acreage.’

3.Crop-based bioplastics require fertile land, water, fertilizers, and are reliant on weather conditions. This means that the supply of raw materials for bioplastics are at risk of natural phenomena, such as drought.

Answer:

Three advantages of bioplastics:

1. Saving fossil fule

2. Reduction of greenhouse gas emission

3. Reclamation of by-products

Three disadvantages of bioplastics:

1. It won't biodegrade in a landfill

2. It contaminate plastic recycling streams

3. It encourage people to litter more
