Answer:
The enzyme's active site binds to and stabilizes the transition state, which decreases the activation energy of the reaction.
Explanation:
Enzymes are complex multi-folded forms of proteins - they promote chemical reactions in biological processes.
Typically, molecules collide at random, and complex chemical reactions require the right molecular orientation and energy to react (breaking and forming bonds).
Enzymes lower energy needs by providing an alternative reaction pathway and stabilize and maintain the molecules in their intermediate forms called transition states.

Explanation:
The human immunodeficiency virus (HIV) is a retrovirus (genus Lentivirus) whose genetic material is a positive-sense single-stranded RNA. HIV is known to infect HIVcells of the human immune system such as, for example, macrophages, T cells, dendritic cells, etc., eventually leading to the acquired immunodeficiency syndrome (AIDS). Within host cells, the HIV genome is reverse transcribed into DNA by using a specific enzyme called reverse transcriptase. Then, this DNA is integrated into the genome of the host cell, replicating when the host cell replicates. Moreover, the integrated HIV genome can also be transcribed to produce RNA and proteins capable of infecting new cells.
what structure is less likely to suffer severe damage during an earthquake a high-rise steel frame Hotel built on segments or a wood frame house built on bedrock explain.
Answer:
Wood frame house built on bedrock
Explanation:
The wood frame house built on bedrock is less likely to suffer severe damage because it has a firm bedrock foundation and can be easily repaired and shape recovered since it would just be shaken whereas, the high-rise steel frame hotel built on segments will suffer more damage because it doesn't have as much of a firm foundation like the wood frame house and as such the high rise will fall over and be more difficult to recover due to the severe damage.
What influence does acid rain have on seed germination?
Answer:
Acid rain is an umbrella term, which is used
to cover a number of different pollution
processes. The pH of acid rain is ten, fold
difference between numbers. India illustrates
the drastic effect of acid rain on agricultural
productivity researchers there found that
wheat growing near a coal fired power plant
where SO2 deposition was almost five times
greater than the critical load (the amount of
the soil can safely absorb without harm)
suffered a 49% reduction in yield. In the
present investigation to assess the effect of
acid rain on the plant growth, the plant of
Triticum aestivum and Raphanus sativus
were grown in different wooden boxes and
three different plastic boxes. The different pH
(2.0, 4.0, 5.0) of simulated rain does were
sprayed on the plant and after last dose the
specific visual difference was seen in seed
germination. increased acidic level (pH 2.0) of the rain water affects the seed germination by the rate of 40% as compared to that of lower level of acidity (pH 4.0 and 5.0)

A new virus has been identified by DNA sequencing methods in a remote location in the South Pacific. The World Health Organization is very concerned because infection with this virus has a death rate of 20% of all infected individuals and no vaccine is available. This is an example of a(n) _____ disease.
Answer:
an emerging infectious disease
Explanation:
According to the World Health Organization (WHO), an emerging infectious disease can be defined as a newly identified and previously unknown infection in a population that may lead to serious public health concerns at local and/or international level. Emerging infectious diseases usually are caused by pathogenic organisms (like viruses) already present in the environment that acquire the ability to infect a new host species as an adaptive response to changes in ecological conditions. Some examples of emerging infectious diseases include, among others, Ebola virus disease, Chikungunya virus disease, H1N1 Influenza virus disease, etc.

Explanation:
According to mendels ______ one copy of a gene is passed randomly from each parent to their offspring. this is why gametes usually have half the usual number of chromosomes.
Answer:
Law of Segregation
Explanation:
Gregor Mendel was a scientist known for experimenting the pea plants in relation to the topic on "Heredity." Under this, he came up with the "Law of Segregation." This states that an organism only receives one gene copy of every gamete once it makes gametes. This is also "randomly selected." This is the reason why only one copy of a gene is passed from each parent to the offspring. In order to check the allele combinations, a "Punnett square" is being used.

Dakota lives in New Orleans. He knows that scientists have predicted some changes on Earth due to global warming, and he is concerned it will affect his city.
If the climate warmed, which of the following would be caused by rising temperatures?
A. a decrease in the amount of flooding in coastal areas
B. an increase in the amount of solar energy that gets reflected
C. an increase in sea levels
D. a decrease in sea levels
Answer:
The rising global temperatures will lead to an increase in sea levels.
Explanation:
The rise of global temperatures is a natural process that has been occurring numerous times during Earth's past. What is different in the current one though is that humans also have an impact on it and have managed to speed up the process with their activity. Every increase or decrease of global tempeartures results in big changes.
With global temperatures rising, the cryosphere (ice surfaces) will decrease due to melting. How much will the ice surfaces decrease can't be predicted, but even if it's one third or one half of them, the sea levels will rise because they will get huge amounts of water from their melting. This will result in rising in sea levels and that will mean that a lot of the human population will need to migrate and a lot of the biggest cities in the world will be underwater. Such is the case with New Orleans, but also the big cities in the northeast of the United States. Not just cities though, but there are countries that can totally or almost totally be underwater, with the Netherlands, the Baltic States, many Pacific nations being among the most damaged.
Answer: THE ANSWER IS C.) "an increase in sea levels"

• 10. What do environmental scientists study?
Answer:
See detailed explanation.
Explanation:
Hello!
In this case, since the environmental science is the branch of science that focuses on natural phenomena, impact of the human activities, pollution prevention and many others, we can notice it is also an interdisciplinary science involving biology, ecology, physics, chemistry, zoology and other branches of natural science because it goes over the environment and the living things dwelling into it.
It means that the environmental scientists study how the ecosystems behave, how we can conserve them despite the pollution and human dangerous activity, how they have changed along the years and how they are going to be as the years go by.

Which ecological concept best categorizes weather (i.e., temperature) as a limiting factor in yellow jacket wasp survival?
population birth rate
O population death rate
Odensity-dependent factors
O density-independent factors
Answer: density-independent factors
Explanation:
The ecological concept that best categorizes weather (i.e., temperature) as a limiting factor in yellow jacket wasp survival is referred to as density-independent factors.
Density-independent factor, is also referred to as limiting factor, and it simply means the things that have an impact on the population of the living things in a particular area without taking into consideration of the density of the population for the area e.g food limitation, weather conditions, pollutants, fire etc.
Select all that are true. A short tandem repeat (STR):
A. Is a repeated sequence of DNA within a gene coding sequence
B. Can only be identified through restriction enzyme digest analysis
C. Is a repeated sequence of DNA in a non- coding sequence
D. Can be composed of a variable number of repeats in different people
E. Is a mutation in a gene
Answer:
C. Is a repeated sequence of DNA in a non- coding sequence
D. Can be composed of a variable number of repeats in different people
Explanation:
Short Tandem Repeats (STRs) are short DNA motifs, i.e., short nucleotide repeat units (generally 2-7 base pairs in size) that may have a different number of repeats among individuals (alleles). Polymorphic STR sequences are very useful genetic markers and therefore they are used for different purposes, e.g., for constructing genome linkage maps, identification of individuals and/or populations, paternity testing, etc. For example, in the USA, the Combined DNA Index System (CODIS) is a databank that stores different DNA profiles based on 13 core STR loci which are used in forensic identity testing.
