Answer:
Insertion
Explanation:
Mutation is generally referred to as any change or alteration that occurs to the nucleotide sequence of a gene. There are several types of mutation depending on how it occurs. The types of mutations are; substitution, insertion, deletion, etc.
Insertion mutation is a type of mutation in which one or more nucleotide base is added a sequence. This is the case in this question about an original sequence that reads: AGTATA. We then have the mutated sequence as follows: AGTATTA
Notice that, nucleotide "T" has been added in between T and A. Hence, a type of INSERTION mutation.

Answer:
The correct answer is -
Notochord= Chordates
Endoskeleton= Deuterostomes
Nucleus+mitochondria= Eukaryotes
Single flagellum= Opisthokonts
Amniotic egg= Reptiles, birds, and mammals
Ecdysus= Ecdysozoa
Explanation:
The notochord is a flexible rod-like structure that is present in all chordates in their embryological stage and gives its name Chordata. It gives support through the length of the body and present between the nerve cord and digestive tube.
All vertebrates especially deuterostomes have an endoskeleton made up of bones or cartilage.
Nucleus and mitochondria are two double-membrane structures present in all eukaryotic cells and organisms.
Opisthokonts have a characteristic feature to have flagellated cells. These organisms have a single posterior flagellum. Amniotic eggs are produced by birds and reptiles only.

Transitional fossil evidence shows intermediate steps in the evolution process. So, the correct option is A.
What do you mean by Fossil?Fossils may be defined as the preserved remains, or traces of remains, of ancient organisms. They are dead and organic remains of past organisms.
Transitional fossil evidence would show intermediate forms of a species and they changed and accumulated adaptations at a slow pace. These are remnants of an organism that came in the version of the current species.
Therefore, Transitional fossil evidence shows intermediate steps in the evolution process.

George Box, a famous statistician, once said, "All models are wrong, but some are useful.” What did George Box mean by this statement?
Answer:
The 2nd part, "But some are useful" - simplifications of reality can be quite useful. They can help us explain, predict and understand the universe and all its various components. The idea of this quote is that every single model will be wrong, meaning that it will never represent the exact real behaviour.
George Box, a famous statistician, once said: "All models are wrong, but some are useful" he made an aphorism stating that mathematical models are flawed.
What is an aphorism?Maxim or sentence that, in a few words, explains a rule or principle of moral significance; apothegma, saying. “Short and succinct text, foundation of a fragmentary and unsystematic style in philosophical writing.

An animal with a larval form that disperses by drifting in ocean currents and an adult form that is attached to a surface is most likely to exhibit ______ as a larva and ______ as an adult. bilateral symmetry . . . bilateral symmetry bilateral symmetry . . . be asymmetrical radial symmetry . . . radial symmetry radial symmetry . . . bilateral symmetry bilateral symmetry . . . radial symmetry
Answer:
Bilateral symmetry as a larva
Radial symmetry as an adult
Explanation:
Bilateral symmetry refers to the division of the animal through a longitudinal plane, int two mirror-image, right and left halves, as seen in organisms such as insects, reptiles or in man. Animals with bilateral symmetry have anterior and posterior halves (head and tail), dorsal and ventral (front and back), and right and left sides. Most animals are bilaterally symmetrical. Animals with bilateral symmetry are best suited for active lifestyles involving streamlined and directional motion.
Radial symmetry refers to the arrangement of body parts around a central axis, just like rays on a sun, ie.they have bodies that seem to radiate outwards from a central point. Animals that are radially symmetrical have top and bottom surfaces only but no left and right sides, or front and back sides. Animals that have radial symmetry are best suited for sedentary lifestyles and are usually attached to some surface (sessile)
An animal with a larval form that disperses by drifting in ocean currents and an adult form that is attached to a surface is most likely to exhibit bilateral symmetry as a larva and radial symmetry as an adult.

Microbial food fermentation is often performed as a preservation method to inhibit the growth of food spoilage microorganisms that may be present in or on the food. The fermentation process often leads to an overall pH decrease of the food to levels below 4. This drop most likely causes many ________ to be inhibited.
Answer:
This question lacks options, options are:
A. Acidophiles B. Alkaliphiles C. Neutrophiles
The correct answer is A. This drop most likely causes many acidophiles to be inhibited.
Explanation:
Microbial fermentation is one of the basic biotechnical processes for the efficient formation of active substances. Fermentation uses fungi, bacteria or cell cultures to transform raw materials into chemicals. Acidophiles is usually bacteria and other very simple organisms that are capable of developing in conditions of too low a pH for most forms of life. Each microorganism has a pH range in which it can grow and a well-defined optimum pH. Depending on the pH, we find acidophiles (1.1 - 5.5), neutrophilic (5.5 - 8.0) and alkaline (8.5 - 11.5) microorganisms, which grow well in acidic, neutral and alkaline pH respectively. Fermentation is carried out to prevent the development of other microorganisms that can alter the quality of the food. Anaerobic digestion is a microbial fermentation in the partial or total absence of oxygen that gives rise to a mixture of gases, in which methane and carbon dioxide are mainly found. Anaerobic microorganisms mainly obtain their energy through the use of fermentation pathways, where organic compounds such as acids and alcohols, among others, basically serve as final electron acceptors. Bacteria, in carrying out these processes, are conditioned by some physical and chemical factors, which enable their proper development, these factors are: loads of organic matter, volatile fatty acids, temperature, alkalinity, nutrients and the presence of N and P , among others.
The digestion of food in the absence of oxygen and release of oxygen is called fermentation.
Microbes that perform the fermentation are usually anaerobic bacteria.
Microbial food fermentation is often performed as a preservation method to inhibit the growth of food spoilage microorganisms that may be present in or on the food. The fermentation process often leads to an overall pH decrease of the food to levels below 4. This drop most likely causes many acidophiles to be inhibited.
Acidophiles or acidophilic organisms are those that thrive under highly acidic conditions.
The lower ph makes the food acidic, due to acidic in nature the bacteria are not able to survive in that conditions.

Two protein kinases, PK1 and PK2, work sequentially in an intracellular signaling pathway.You create cells that contain inactivating mutations in the genes that encode either PK1 or PK2 and find that these cells no longer respond to a particular extracellular signal.You also create cells containing a version of PK1 that is permanently active and find that the cells behave as though they are receiving the signal even when the signal is not present.When you introduce the permanently active version of PK1 into cells that have an inactivating mutation in PK2, you find that these cells also behave as though they are receiving the signal even when no signal is present.
A.From these results, does PK1 activate PK2, or does PK2 activate PK1? Explain your answer.
B.You now create a permanently active version of PK2 and find that cells containing this version behave as though they are receiving the signal even when the signal is not present.What do you predict will happen if you introduce the permanently active version of PK2 into cells that have an inactivating mutation in PK1?
Answer:
a. PK2 activates PK1
b. no response would be produced
Explanation:
Kinases are enzymes known to phosphorylate different substrates, thereby activating/inactivating them. In this case, a mutation that produces a constitutively (permanently) active PK1 kinase is itself able to continue the signaling pathway, independently of whether or not PK2 is present. This constitutive mutation shows that PK1 is recruited to continue signaling events within the cell and, therefore, PK1 activation is downstream in the signaling pathway. Conversely, cells containing active PK2 and inactive PK1 would be unable to continue the signaling pathway since PK2 activation is upstream of the induction of PK1, and thereby these cells cannot respond to the signal (PK2 activation).
