An amoeba is a single-celled organism that feeds on algae, plant cells, and bacteria. When an amoeba feeds, it first makes contact with the food particle. Next, the amoeba starts to surround the particle. Once the particle is completely engulfed, it is surrounded by a layer of the amoeba's membrane, forming a vesicle. The pH in the vesicle is then lowered and the contents are degraded.

What type of transport is involved in this process?

A.
endocytosis
B.
diffusion
C.
passive transport
D.
exocytosis

Answers

Answer 1

Answer:

A.  endocytosis

Explanation:

Endocytosis is the type of transport that is involved in this process because it engulf the food material. Amoeba engulfs food particles with the help of its pseudopodia which are the projections of cell membranes. A food vacuole is formed around the food particle. This process of engulfing a matter by the projections of the cell membrane to form a vacuole is called endocytosis.

What is extinction?

Extinction is defined as the disappearance of an organism or a group of organisms as a result of environmental factors or changes in the members' evolutionary processes.

It can also be defined as an evolutionary process that causes a species or population to go extinct.

When there are no longer any living members of a certain animal or plant species anywhere in the globe, the species has become extinct.

Generally speaking, species disappear for the following reasons:

Genetic and demographic phenomena.Habitat destruction in the wild.Species introduction that are invasive.Global warmingHunting and illicit trade.

Some broad-spectrum proteases (protein hydrolyzing enzymes) and nucleases (nucleic acid hydrolyzing enzymes) that function in eukaryotic cells have an optimum pH close to 5.0, whereas the cytosol of most cells is closer to pH 7.0. Which part of a eukaryotic cell might you predict to have a low pH suited to maximizing the activity of these enzymes

Answers

Answer:

lysosome

Explanation:

The lysosome is a membrane-bound organelle found in nearly all eukaryotic cells. The lysosome contains different types of enzymes (i.e., proteases, nucleases, glycosidases, lipases, phosphatases) which are required for the digestion of macromolecules and microorganisms, and recycle macromolecules in the cell. These enzymes are only active in acidic (lysosome) conditions, and they can be deactivated in case of lysosomal rupture because in the cytosol the pH is neutral to slightly alkaline (∼7.3–7.4).

Insects: Please choose the correct answer from the following choices, and then select the submit answer button. typically have a younger flying life stage and an older aquatic life stage after metamorphosis. generally give birth to live young. typically mate and produce young during their larval stage. have a respiratory system with spiracles connecting to tracheae.

Answers

Answer:

The correct option is ( have a respiratory system with spiracles connecting to tracheae).

Explanation:

The class INSECTA are under the phylum arthropoda which is the largest phylum in the animal kingdom. The insects are mainly land animals, they are widespread and adapted to all types of environment. They are also the only invertebrates that can fly. Examples of insects include: ants, butterflies, beetles, aphids and grasshoppers.

An insect has a well-defined head, thorax and an abdomen. The head had six segments and bears a pair of jointed antennae, compound eyes, simple eyes and mouthparts. The thorax had three segments, each bearing a pair of jointed walking legs. The abdomen has eleven segments and may have sensory and reproductive structures.

An insect carries out gaseous exchange by means of a network of open air tubes or TRACHEAE inside it's body. These tubes have openings called SPIRACLES to the exterior. Therefore the insects have an respiratory system with spiracles connecting to tracheae.

If an area has very little permeability, such as a city where the ground is mostly concrete, what will happen to most of the rainwater?
A. It will become groundwater.
OB. It will be pumped into underground reservoirs by large machines.
C. It will become runoff.
D. The type of surface it falls on does not affect rainwater.

Answers

Answer:

C

Explanation:

The water won't be able to penetrate the ground so can't become ground water and reservoirs are usually above ground not underground so it will become run off.

Permeability is the ability of the substances to get diffused easily across the surface. The concrete ground results in the rainwater becoming runoff. Thus, option C is correct.

What is permeability?

Permeability is the capacity of the water or any fluid to pass and diffuse across the substances or any membrane to get from the higher to lower concentration.

The concrete ground and roads are not permeable and do not allow water to pass through the material and effects the collection of the rainwater through infiltration.

The rainwater is unable to filter into the groundwater and becomes runoff. This runoff gets accumulated on the roads and can even lead to floods and drain blockages.

Therefore, option C. the less permeable roads cause rainwater to become runoff.

Write a supported hypothesis of how the body would react if the peripheral nervous system was shut down while the central nervous system continues to function.

Answers

Explanation:

The real magnitude of this challenge can perhaps be best judged by considering the structural and functional complexity of the human brain and the bewildering complexity of human behavior. The human brain is thought to be composed of about a hundred billion (1011) nerve cells and about 10 to 50 times that number of supporting elements or glial cells. Some nerve cells have relatively few connections with other neurons or with such effector organs as muscles or glands, but the great majority receive connections from thousands of other cells and may themselves connect with several hundred other neurons. This means that at a fairly conservative estimate the total number of functional connections (known as synapses) within the human brain is on the order of a hundred trillion (1014). But what is most important is that these connections are not random or indiscriminate:

They constitute the essential "wiring" of the nervous system on which the extraordinarily precise functioning of the brain depends. We owe to the great neuroanatomists of the last century, and especially to Ramón y Cajal, the brilliant insight that cells with basically similar properties are able to produce very different actions because they are connected to each other and to the sensory receptors and effector organs of the body in different ways. One major objective of modern neuroscience is therefore to unravel the patterns of connections within the nervous system—in a word, to map the brain.

What are the methods of waste disposal ? Write in briefly.​

Answers

Answer:

Methods of waste disposal are :-

Biogas plant: - Biodegradable material is used to produce biogas and manure.

Sewage treatment plant: The drain water is treated at plants before adding it to river.

Land filings: - The waste are buried in low-lying areas and compacted with bulldozers.

Composting: - Organic waste are filled in compost pit to make compost for plants.

Recycle: - This means that you collect plastic, paper, glass and metal items and recycle these materials to make required things instead of synthesizing or extracting fresh plastic, paper, glass or metal. In order to recycle, we first need to segregate our wastes so that the material that can be recycled is not dumped along with other wastes.

Reuse: - This is actually even better than recycling because the process of recycling uses some energy. In the ‘reuse’ strategy, you simply use things again and again. Instead of throwing away used envelopes, you can reverse it and use it again. The plastic bottles in which you buy various food-items like jam or pickle can be used for storing things in the kitchen.

Refuse: -This means to say No to things people offer you that you do not need. Refuse to buy products that can harm you and the environment, say No to single-use plastic carry bags.

Repurpose - This means when a product can no more be used for the original purpose, think carefully and use it for some other useful purpose. For example, cracked crockery, or cups with broken handles can be used to grow small plants and as feeding vessels for birds.
