The enzyme could become spatially distorted, thus reducing the ability of the active site to catalyze the reaction. Tight enzyme-substrate binding will reduce the forward rate constant for the reaction. Tight binding of the enzyme to its substrate will pull the substrate out of solution, thus decreasing the driving force for the forward reaction. Tight binding of the enzyme to its substrate will result in the enzyme-transition state complex being higher in energy than with weaker binding. All of the above.
Answer:
All of the above.
Explanation:
All the given options are the potential disadvantage of an enzyme that have a very high affinity for its substrate.
The enzyme can be distorted spatially and thus reduces the ability to catalyze the reaction of the active site.
The tight binding of an enzyme to a substrate results in enzyme transition state complex which is higher in energy.
The tight binding also pulls the substrate out of the solution and decreases a driving force in the forward reaction.

In Wakanda, in a population in Hardy-Weinberg equilibrium, the frequency of the single recessive allele controlling vibranium assimilation, which affects superhuman abilities, is 0.2. What is the percentage of the population that is heterozygous for this allele
Answer:
32%
Explanation:
Hardy–Weinberg equilibrium is also known as Hardy–Weinberg law. The idea of Hardy–Weinberg equilibrium is about the frequency of alleles in a population. The frequency of an allele in the population will always remain the same in a population if that population is not influenced by any evolutionary consequences.
Hardy–Weinberg equilibrium binomial expression formula is p2+2pq+q2=1. Suppose the frequency of recessive allele = q.
and another normal allele is = p
Here Q = 0.2 so P will be 1- Q or 0.8
By Hardy–Weinberg equation p2+2pq+q2=1, Here 2pq denotes the frequency of recessive allele, so 2pq = 2 × 0.2 × 0.8 = 0.32, if converted into percentage it will be 32%.

a) In how many cases in the genetic code would you fail to know the amino acid specified by a codon if you knew only the first two nucleotides of the codon?
b) In how many cases would you fail to know the first two nucleotides of the codon if you knew which amino acid is specified by it?
Answer:
a) 28 cases
b) 3 cases
Explanation:
a) From the table of genetic codes, there are 28 codons that specify more than one amino acid assuming only the first two nucleotides are considered. In these cases, one cannot outrightly specify the amino acid the genetic codes are coding for without knowing the last nucleotide of the codes. For example, UU can be for Phenylalanine or Leucine, CA can be for Histidine or Glutamine, etc.
b) From the table of genetic codes, the first two nucleotides of Arginine can be either of CG or AG, that of Serine can be either of UC or AG while that Leucine can be either of CU or UU. Only in these 3 cases would one fail to know which are the first two nucleotides assuming the name of the amino acids are given.

This animal has a protostome developmental pattern and a trochophore larva. Identify the major clades that this animal belongs to
Answer:
Lophotrochozoans (it is a protostome)
Explanation:
Lophotrochozoa is a group (clade) of protostome animals, i.e. animals that undergo a developmental pattern in which the blastopore develops into the mouth. Lophotrochozoa clade includes bryozoans, annelids, molluscs, brachiopods, and platyhelminthes. Most lophotrochozoans have either a lophophore or trochophore larvae during the planktonic stage. A trochophore larva is a marine planktotrophic larva with several bands of cilia that form the locomotory organ (i.e., the prototroch), which is only found within the Lophotrochozoans.
When the larva and the adult form of an organism are different from each other this type of development is called indirect development. For example Porifers and platyhelminthis.

During the process of cellular respiration, carbon dioxide is given off as a waste product. This carbon dioxide can be used by photosynthesizing cells to form new carbohydrates.
Most angiosperms incorporate the assistance of animals in their reproductive cycle. This is a major advancement that gave them an advantage over other plant lineages and helped them become the dominant type of plant on Earth today. Which of the following steps in the reproduction of angiosperms do animals assist with? Check all that apply.
A. Pollination
B. Seed dispersal
C. Fertilization
Answer: The steps in reproduction of angiosperms that animals assist with is
a.) Pollination
Explanation:
ANGIOSPERMS are flowering plants that forms the largest group in the plant kingdom. The angiosperms are more highly evolved than other plants because they have an abundance of water- conducting vessels and bear seeds which are protected within fruits. Fruits develop from the ovaries of flowers, the female reproductive organ of the angiosperms.
Pollination is only the first step in the process of sexual reproduction in flowering plants. It is followed by fertilization and development of the zygote. These steps change the flower into a fruit enclosing seeds. Pollination in flowering plants involves the transfer of pollen grains from an anther to a receptive stigma.
Pollination depends on external pollinating agents known as pollinators. These include
--> insects and
--> animals such as birds, squirrel,bats and snails.
Animals such as birds perceive red colour more clearly than insects. They are also larger than insects and unlike insects have a poor sense of smell. As a result, flowers of plants that are pollinated by birds are usually Res with no scent. While flowers pollinated by insects are scented and produce nectar. As they visit the flower, they become covered with the pollen from the mature anthers of the flower. These pollen grains are eventually transferred to the stigma of another flower of the same species leading to fertilization which is a step in plant reproduction. Therefore, pollination is a step in reproduction of angiosperms that animals assist.
Answer:
B. Seed dispersal
Explanation:
Seed dispersion is an ecological process very important in keeping ecosystemic biodiversity and in vegetal communities regeneration. There are many types of dispersion. But probably, zoocory is one of the most significant types of seed dispersion.
There are two types of zoocory:
Exozoocory: refers to the transport of seeds in the fur or feathers of animals.Endozzocory: refers to the ingestion of the seeds and the posterior excretion.By endozoocory, herbivores are significant not only for dispersing the seeds but also for scarifying them. When seeds pass along the digestive system of the animals, the whole digestive process eliminates or debilitates the cuticle and other external structures, increasing the proportion and speed of germination.
Many vertebrates are involved in seed dispersion, but birds and frugivorous bats play an important role in dispersing seeds far away from the parental plant, playing an important role in the natural ecosystem regeneration processes.

Together the scientists analyzed and compared cave drawings of various species of prehistoric animals from different parts of the world.
Each scientist worked in isolation to experiment on fossils and prove their beliefs regarding evolution. Yes
They made documented and shared many scientific observations related to biogeography and comparative anatomy . So, the correct option is (C).
What is Theory of Evolution?The theory of evolution, also called the "theory of evolution by natural selection", was proposed by Charles Darwin and Alfred Russel Wallace in the nineteenth century.
Darwin further stated that species can change over time, that new species come from pre-existing species, and that all species share a common ancestor. In this theory, each species has its own distinct lineages or genetic differences that come from a common ancestor, gradually accumulating over a very long period of time.
This theory explained that birds had moved from the mainland to the islands, and that species gradually evolved to fit their new environments. Natural selection occurs because organisms in a population usually have randomly occurring gene variations and mutations that affect adaptation.
Thus, they made documented and shared many scientific observations related to biogeography and comparative anatomy . So, the correct option is (C).

Which of the following is not associated with the parasympathetic division of the autonomic nervous system (ANS)?
a. resting.
b. energy conservation.
c. emergency action.
d. digesting.
Answer:
a
Explanation:
The autonomic nervous system (ANS) is involved in breathing and heartbeat. Emergency action is not associated with the parasympathetic division of ANS. Thus, option c is correct.
What is ANS?ANS is abbreviated for the autonomic nervous system and is a sub-division of the peripheral nervous system. It includes actions that do not require consciousness and can regulate involuntary actions.
The ANS is sub-divided into sympathetic and parasympathetic nervous systems. The latter division is involved with resting, energy conservation, and digestion. It regulates the various body functions.
Parasympathetic nervous systems regulate the breathing rate, digestion, heartbeat, and blood flow, as they all are involuntary physiologic processes. They even show acute stress response but not emergency actions.
Therefore, option c. the emergency responses are not associated with parasympathetic nervous systems.
