Choose the CORRECT statement about enzymes below.
Group of answer choices
Enzymes raise the activation energy needed in a chemical reaction
Enzymes slow down the rate of chemical reactions
Enzymes function best at specific pH and temperatures
Enzymes are carbohydrates and store short term energy
Answer:
Enzymes function best at specific pH and temperatures.
Explanation:
An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.
Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.
Hence, the correct statement about enzymes is that enzymes function best at specific pH and temperatures. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.

l. A farming area developed a major locust problem. Swarms of locusts were destroying crops and the environment. A team of
scientists developed an infectious disease that would reduce the population of locusts What would be most important to find
out before producing and releasing the disease?
how a decreased number of locusts would affect other organisms
which species might eat the crops in the absence of locusts
how the disease can be used for other applications
O how quickly farmers would get to see the results
Answer: how a decreased number of locusts would affect other organisms.
Explanation:
When engaging in any action aimed at destroying large numbers of an organism as is the case here, there is always a need to check what impact it might have on the ecosystem at large.
This is why it is very important that the effect of a decreased number of locusts on other organisms is evaluated before such drastic action is taken. If it would lead to a situation where the ecosystem is destabilized, the consequences would be far reaching and very damaging.
How a decreased number of locusts would affect other organisms is the
most important to find out before producing the disease.
What is Population?This is referred to the number of organisms present in an area over a
specific period of time.
We were told that swarms of locusts destroyed the environment and
needed to be reduced through the creation of a disease. The effect the
decrease in locust has on other organisms has to be considered to ensure
the ecosystem is balanced and doesn't adversely affect others.

How long does it take to make paper out of cow manure? I only need a direct answer please.
Answer:
a few hours to a few days
Explanation:
Reports that a process can exist do not mention the time involved.
In an industrial process, the length of time likely will be dominated by cleaning, bleaching, and drying times, which could be hours to days. Full-scale production would likely be more efficient if time is shorter. If "appropriate technology" is used, time could run to several days.

How is structure of DNA adapted to its function
Answer:
Deoxyribonucleic acid is the macromolecule carries the genetic information. It has two phosphate sugar back bone chains which are joined together with the help of nucleotides (A, T, G, and C). This set of nucleotide refers as gene. These genes define the primary function of DNA to carry genetic information. This DNA structure gets coiled in manner that can carry large amount of information. These nucleotide sequences have ability to get transcribed into protein molecule with the help of translation and transcription factors.
One strand of sequence is sufficient to maintain coding sequence. The pair wise structure helps in case of one strand of structure get damaged and it required in process of replication.
Base stacking provides the stability in the structure of the DNA. The corresponding nucleotides combine with other molecule and minimize the hydrophobic effect. This molecule combines in the perpendicular alignment to the DNA base line.
It often found that TATA box on 5’ end. It is found that on 5’ because process starts from 5’ end and TATA box have A, T nucleotide. These molecules have double hydrogen bond, which is weaker then G, C pair.
Explanation:
The structure of DNA adapted to its function - DNA contains the instructions needed for an organism to develop, survive and reproduce.
DNA sequencesDNA has nucleotide made up of pentose sugar and phosphate backbone, and nitrogenous bases in a particular sequence.The sequence converted into messages that can be used to produce proteins, which are the complex molecules that do most of the work in our bodiesDNA winds into a double helix, with hydrogen bonding between the bases of each strand like the rungs of a ladder.The order of nucleotides in a gene dictate the amino acid sequence of the proteinDNA acts to store information while proteins are the effector molecules.
Thus, The structure of DNA adapted to its function - DNA contains the instructions needed for an organism to develop, survive and reproduce.

Which of the following statements about human society and limiting factors is true?
a. Modifications made to the environment to reduce the impact of limiting factors can cause
disruption to the natural balance of an ecosystem.
b. Humans cannot modify their environment to adapt it to their needs.
c. Humans can completely overcome the factors that limit population size.
d. Limiting factors are of no concern to human society, because they do not affect human
populations
The statement that is true about human society and limiting factors is "Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem." The correct option is A.
What are limiting factors?Limiting factors are the factors that limit the growth of populations. For instance, the limiting factors for humans might be a lack of food or water. Limiting factors may be biotic or abiotic. Abiotic factors include nonliving aspects like temperature and rainfall while biotic factors are the living aspects like predators and competition.
Modifications made to the environment to reduce the impact of limiting factors can cause disruption to the natural balance of an ecosystem. These modifications include the introduction of a new species, the clearing of land for agriculture or industry, or pollution.
The new species can lead to the elimination of the native species, the clearing of land can cause habitat loss, and pollution can have numerous effects like air and water pollution.
Therefore, the correct option is A.

Hypersecretion of growth hormone after normal growth has ceased may cause
acromegaly
achondroplastic dwarfism
pituitary dwarfism
gigantism
Answer:
gigantism
Explanation:
The growth hormone is responsible for stimulating normal growth in humans or in other words, stimulating growth at a normal pace. To do this, the growth hormone must be released in optimal quantities, however, an hypersecretion i.e. excessive release of the hormone will cause a fast and uncontrollable growth in certain regions of their body or the whole.
This abnormal excessive growth caused by an excessive release of the growth hormone is called GIGANTISM. Gigantism occurs mostly in children at their growing phase.

Thoroughbreds are an example of a type of horse that results from selective breeding. However, not all thoroughbreds have the traits that are most desired. How has the process of selective breeding increased the probability that the horse will have a desired trait? Use information from the stimulus material and your knowledge of science in your answer. In your answer, be sure to:
Explain how selective breeding increases the probability that offspring will have a desired trait.
Explain why not all individual thoroughbreds may express the desired traits.
Answer:
If breeders Breed these horses with other breeds, the foal wont be a straight thoroughbred. So, it will change the horses breed.
Explanation:
Selective breeding increases the probability that offspring will have the desired trait because it limits narrows the gene pool to only include desired variants of a gene. Not all thoroughbreds may express the desired trait because they may inherit an unwanted variant of the gene & mutations may occur.
The traits and characteristics of an animal are determined by the genes they possess. When two animals breed, the offspring inherits one variant of each gene from both parents, known as alleles. This means that all animals have 2 variants for any specific trait.
When a gene in an allele is expressed, it means that the genetic code in that allele is the one that can be seen on the offspring. Gene variants can be classified based on how likely they are to be expressed as:
Dominant RecessiveWhen one allele is expressed and the other is not, it is because that allele is dominant and the other is recessive. Recessive variants for a gene will only be expressed if both alleles inherited by the offspring possess are recessive. dominant genes are symbolized by a capital letter and recessive genes with a lower-case letter.
Selective breeding is used to continuously breed animals that have similar variants of the desired trait. If breeding were to be natural, then many of what we consider desirable traits may be lost behind the expression of common, more dominant genes. Selective breeding is done by narrowing the gene pool, meaning that we only allow breeding between animals known to possess the desired trait.
Not all thoroughbreds may express the desired traits because sometimes even though a parent has the desired variant of a trait, they may also contain a different recessive or dominant variant of a trait. Since selective breeding does not control what variant exactly the offspring inherits, it does not always work with each offspring. Genetic mutations can also affect the outcome.
