how do enzymes help against bacteria and disease​

Answer:

80°C

Explanation:

The change in temperature can be calculated my using the specific heat capacity equation as follows;

Q = m × c × ∆T

Where;

Q = amount of energy (J)

m = mass (kg)

c = specific heat capacity of water (J/kg°C)

∆T = change in temperature (°C)

According to this question, Q = 201,600J, m = 600g = 600/1000 = 0.6kg, c of water = 4200J/kg°C

Using Q = m × c × ∆T

201600 = 0.6 × 4200 × ∆T

201600 = 2520 × ∆T

∆T = 201600 ÷ 2520

∆T = 80

Change in temperature (difference in initial and final temperature) is therefore 80°C

Answer:

Independents are all the different liquids used ie: soaps, water, hand sanitizer.

Dependent is the bacteria growth.

Explanation:

This is because you are constantly change the liquids so that is independent. The bacteria growth is dependent since the growth depends on the different liquids.

Answer:

Motor Energy. Energy is moved starting with one article then onto the next when a response happens. Energy comes in numerous structures and can be moved starting with one item then onto the next as warmth, light, or movement, to give some examples. For the blue ball to move to the situation of the green ball, energy should be given to the blue ball.

Answer:

Eukaryotic cells have a true nucleus, which means the cell's DNA is surrounded by a membrane. Therefore, the nucleus houses the cell's DNA and directs the synthesis of proteins and ribosomes, the cellular organelles responsible for protein synthesis.

OR

In the nucleolus, new ribosomal RNA combines with proteins to form the subunits of the ribosome. The newly made subunits are transported out through the nuclear pores to the cytoplasm, where they can do their job.

The nucleolus inside the nucleus produces ribosome components, which are synthesized just outside of the nucleus form ribosomes.

The spindle then sends mRNA towards the ribosomes, which is used to code for protein synthesis.

Other organs in the cell, including the mitochondria and lysosomes, are surrounded by lipid membranes that isolate them from other components in the cell.

Explanation:

Answer:

1a. The template DNA strand, from which the mRNA is synthesized, is 5’ CAAACTACCCTGGGTTGCCAT 3’

(RNA synthesis proceeds in a 5’ à 3’ direction, so the template strand and the mRNA will be complementary to each other)

b. The coding DNA strand, which is complementary to the template strand, is 5’ ATGGCAACCCAGGGTAGTTTG 3’

c. The sequence of the mRNA is 5’ AUGGCAACCCAGGGUAGUUUG 3’

(the sequence of the mRNA is complementary to the template strand and identical to the coding strand with U substituted for T)

d. The third codon is 5’ ACC 3’.  Therefore, the corresponding anti-codon is 5’ GGU 3’

a. The following codons can be mutated by one base to produce an amber codon:

CAG    Gln

AAG    Lys

GAG    Glu

TCG    Ser

TTG    Leu

TGG    Trp

TAA    Stop

TAT    Tyr

TAC    Tyr

b. From part a, CAG (Gln) and TGG (Trp) can become amber stop codons through EMS.

c. From part b, both of the resulting amber codons could be suppressed by amber nonsense suppressors generated by EMS.

3a. The codon is the three nucleotide sequence in the mRNA that indicates which amino acid should be incorporated in the growing polypeptide chain.  The anticodon is the complementary three nucleotide sequence in the appropriate tRNA.

b. Template strand is the DNA strand off which the mRNA is synthesized.  The coding, or non-template, strand is the DNA strand complementary to the template strand; it has the same sequence (except for T for U substitutions) as the mRNA.

c. The Pribnow box is a sequence of six nucleotides (TATAAT) positioned at -10 that signals where transcription initiation should begin in prokaryotic DNA.  The Shine-Delgarno sequence is a short, purine-rich region in the mRNA that is complementary to the rRNA within the 16S ribosomal subunit.  The sequence signals which AUG acts as the translation start in mRNA.

4a. False, a wobble allows the anticodon in the tRNA to hybridize with different codons in mRNA.

b. False, a frameshift mutation affects all the subsequent amino acids.

c. False, only one codon (AUG) encodes for the start of protein synthesis; three codons signal the end of protein synthesis.

d. False, the wobble is first base (5’ to 3’) in the anticodon.

e. True, RNA can be used as a template for DNA synthesis in a process known as reverse transcription.

f. True.  For example, a single base substitution causing CAT to change to AAT would signal a termination.

g. False, the Wobble Hypothesis explains how alternate base pairing can occur with the first nucleotide (going from 5' to 3') in the anticodon.

5a. Digestion of RNA with alkali will cleave the strand after each 3’ phosphate.  Therefore, the products remaining will consist of pppNp, Np, and N-OH

b. If RNA was synthesized in the 3’ to 5’ direction (i.e. by adding ribonucleotides to the 5’ end), then the pppNp and Np fragments should be labeled with tritium.

c. If RNA was synthesized in the 5’ to 3’ direction (i.e. by adding ribonucleotides to the 3’ end), then the Np and N-OH fragments should be labeled with tritium.

d. Since the N-OH fragments were labeled with tritium, RNA synthesis must occur in a 5' to 3' direction.

6. In a missense mutation, the new nucleotide alters the codon so as to produce an altered amino acid in the protein product.  With a nonsense mutation, the new nucleotide changes a codon that specified an amino acid to one of the stop codons (TAA, TAG, or TGA). Therefore, translation of the messenger RNA transcribed from this mutant gene will stop prematurely.

Answer:

True

Explanation:

This is essentially natural selection. If there is a population of giraffes and half of them have long necks and the other half have short necks, the ones with long necks will be more likely to survive because they will be able to reach more leaves on tall trees. This means the ones with short necks will be less likely to survive, so when the long neck giraffes reproduce, they will pass on the gene for a long neck to their offspring. Over time, there will be more and more long neck giraffes and fewer short neck ones.

This is just a silly example but it is actually have animals have evolved over thousands of years lol

Explanation:

The environmental conditions in the biome greatly affect the plant and animal life that are present in it because only those animals and plants survive or present in that environment who adapted their selves or show tolerance in that environment. If there is change occur in the climatic condition of that environment the animals and plants that have resistance will survive while others disappear or eliminated from that environment.

Answer: (Answers may vary.)

I used this website, that provides US climate data, to obtain climate data for Barrow, Alaska. This part of Alaska has a tundra biome with the following conditions:

Annual high temperature: -8.2°C

Annual low temperature: -14.2°C

Average temperature: -11.2°C

Average annual precipitation (rainfall): 115 mm

Average annual snowfall: 990 mm

Barrow is covered in ice and snow for nine months of the year. During spring, millions of birds return to the area from their southern wintering grounds. Thousands of bowhead and beluga whales also migrate through the area in spring. In this region, the warm and wet period only runs from July to August. Most plants grow during this time. Food is scarce during the coldest period, which runs from December to March. During this time, many animals hibernate to survive.

Explanation:

The ecosystem includes biotic and abiotic factors, where X is a biotic factor and Y is the abiotic factor. Therefore, option A is correct.

An ecosystem is a collection or community made up of both living and non-living things, as well as their interactions. Both natural and artificial ones are possible. There are two parts to any ecosystem: biotic and abiotic components.

An ecosystem can be divided into its biotic constituents, which include all of its living members (plants, animals, bacteria, fungi, etc.), and its abiotic constituents, which include minerals, the environment, soil, water, sunshine, and all other nonliving elements.

Thus, X represents biotic factors and Y represents abiotic factors. Therefore, option A is correct.

Phytoplankton

Explanation:

I am almost positive.

Answer:

The correct answer is A. Since the Earth has a tilted angle of 23.5 degrees as it moves around the sun, the amount of sunlight that is received by the hemispheres vary from time to time. This is mainly responsible for the changes in the temperature and daylight hours, which are the indicators of the changes in seasons.

In this case, when one hemisphere of the Earth is tilted toward the sun, it receives more sunlight than the other end. Therefore, this region experiences summer, wherein the daylight is longer and the temperature is warmer

Answer:

200 g of cheese

Explanation:

From the table attached, we can see that each 100 g of cheese contain 22.5 g of protein. For us to calculate the amount of cheese needed to provide about 45 g of protein, we use the formula:

Amount of cheese for 45 g of protein = (100 g of cheese/ 22.5 g of protein) * 45 g of protein

Amount of cheese for 45 g of protein = 200 g of cheese

Therefore 200 g of cheese would be needed to provide 45 g of protein.
