significance of active transport in food processing ​

Answers

Answer:

Why do we need active transport?

Moving Against a Gradient

Small substances constantly pass through plasma membranes. Active transport maintains concentrations of ions and other substances that living cells require in the face of these passive movements. A cell may spend much of its metabolic energy supply maintaining these processes.

Describe how different perspectives in society can affect scientists: |

Answers

Scientists can be affected in society through different perspectives because since science is a modern and changing subject. The findings of one scientist may not be supported by others. Scientists may perform the same experiments or studies but still be met with different results and come up with different conclusions. For ex: When Galileo Galilei discovered that the Earth was round he told other astronomers yet no one agreed with him since they believed that the Earth was flat due to their own research.

what is some advice you would give to someone who doesn’t know the importance of carrying capacity

Answers

Answer:

For someone who doesn't know the importance of carrying capacity, i would advice him to understand what carrying capacity mean, and then tell him that he should not overcrowd the population of animals or be part of humans overcrowding as it can destroy the ecosystem or resources.

Explanation:

This is because, carrying capacity is the population size that can conviniently live in an habitat with the available resources..

It's very important because, it will ensure that the population size that the resources can sustain can live in the environment so as to prevent degradation of the ecosystem or the environment due to increase in population size.

Suppose DNA polymerase synthesizes DNA at a rate of 1000 bases per minute in a newly discovered bacteria and that bacteria replicates 50% of their chromosome every 40 minutes. Calculate the total number of nucleotides in the bacterial chromosome.

Answers

Answer:

320000 nucleotides

Explanation:

Given that:

The rate of synthesis by DNA polymerase = 1000 bases per minute

The time taken to replicate 50% of their chromosome = 40 min

Thus, the time taken for one complete round of replication = (40 × 2) min

= 80 min

The total number of nucleotides in the newly synthesized strand = 1000 pairs/min × 80 min × 4

= 320000 nucleotides

The total number of nucleotides in the bacterial chromosome is equal to 80000 bp (80 kb).

Bacteria are prokaryotic microorganisms whose genome consists of a single circular chromosome.

In this case, it is possible to obtain the duration of DNA replication from data:

40 minutes (min) >> 50% bacterial chromosome40 x 2 = 80 minutes (min) >> 100% bacterial chromosome

The length of the bacterial chromosome can be easily calculated:

DNA replication rate = 1000 base pairs (bp) per minuteTotal chromosome length: 80 x 1000 bp = 80000 base pairs (bp)

A kilobase (kb) is equal to 1000 base pairs (bp) of DNA, thereby in this case the bacterial genome is equal to 80 kb.

In conclusion, the total number of nucleotides in the bacterial chromosome is equal to 80000 bp (80 kb).

If green plant cells are incubated in the presence of CO2 molecules containing radioactive carbon atoms, the fate of the carbon atoms can be followed. In an experiment, radioactive CO2 was given for 1 minute to plant cells, and then the cells were examined after 1, 5, 10, 20, and 30 minutes. The following molecules were labeled with radioactive carbon at some point(s): glucose, glyceraldehyde 3-phosphate, glycine (an amino acid), 3-phosphoglycerate, ribulose 1,5-bisphosphate, and sucrose. List these molecules in the order in which they first become labeled.

Answers

Answer:

glycine (an amino acid)ribulose 1,5-bisphosphate3-phosphoglycerateglyceraldehyde 3-phosphateglucosesucrose.

Explanation:                          

The glycine, among other amino acids, helps to improve chlorophyll production and promotes the process of photosynthesis.

Calvin cycle

During the carbon fixation phase, a CO² molecule combinate with a ribulose 1,5-bisphosphate to form 6-carbonated molecules, which will divide into two 3-phosphoglycerate molecules.

During the reduction phase, NADPH donates its electrons to reduce 3-phosphoglycerate molecules, and turn them into glyceraldehyde 3-phosphate.

During the regeneration phase, a glyceraldehyde 3-phosphate molecule leaves the cycle and goes to the cytosol to form glucose. This step can be done when three CO² enter the cycle and produce six glyceraldehyde 3-phosphate molecules. One of them leaves the cycle to form glucose, while the other five are recycled.

Cytosol:  

Once in the cytosol, glyceraldehyde 3-phosphate molecules are used to form glucose and fructose. These two molecules are the monosaccharides that form the sucrose.          

Once sucrose is formed, it is transported from the photosynthetic tissues to different parts of the plant by the phloem.

nonliving the heat from the hot plate is causing the gel like substance to move it's the same thing with liquid nitrogen how it seems to bounce off the floor it's because liquid nitrogen is super cold and the heat basically excites the electrons in the liquid nitrogen making it bounce off the floor same with the gel like substance the electrons in the gel substance are getting excited by the heat and jumping up and down but the substance itself is not alive

Which is the classification of any naturally occurring solid inorganic substance characterized by a crystal structure? A. fossil B. metal C. mineral D. rock​

Answers

Answer:

C. mineral

Explanation:

In science, matter can be defined as anything that has mass and occupies space. Any physical object that is found on earth is typically composed of matter. Matter are known to be made up of atoms and as a result has the property of existing in states. The three (3) classical states of matter are;

1. Liquid: is the state of matter in which the physical substance can be poured and takes the shape of its container. Also, liquids generally have a definite volume. Examples of liquids are urine, water, milk, blood etc.

2. Gas: is the state of matter in which the physical substance has no definite shape or volume and as a result fills all available space. Also, gases are easily compressible, takes the shape of its container and can flow. Examples of gases are hydrogen, oxygen, argon, nitrogen etc.

3. Solid: is the state of matter in which the physical substance has a definite shape and fixed volume but not compressible. Examples of solids are pen, screwdriver, television, car etc.

Mineral is the classification of any naturally occurring solid inorganic substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.

Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.

Using the Gizmo, determine how coal and petroleum (oil) are formed. Describe the steps required to form each fuel from atmospheric CO2.

Answers

Answer and Explanation:

Petroleum and coal are fossil fuels.  The degradation of the earliest plants forms them. These dead plants started to pile up and form peat. Then the pressure and heat from various geological procedures convert peat into coal. Coal is a combustible rock which contains 50% carbon. Anthracite, Lignite and bituminous are the types of coal, and the formation of coal depends upon the quantity of hydrogen, oxygen and carbon. Petroleum exists naturally in liquid form and formed by decomposed organic matter. Fossil fuels can be refined into usable substances. Gasoline, tar, lubricants and many other products are obtained from petroleum. There are two steps, which required to form fuel from atmospheric carbon dioxide. In first step carbon dioxide is converted into carbon monoxide. In the second step, carbon monoxide combines with hydrogen to form hydrocarbon fuels. The formation of fuel is a natural process when animals respire carbon dioxide release in the atmosphere.
