Answer:

DDDDDDDDDDDDDDDDDDDDDDDDDD

Answer:

The answer is C.

Explanation:

This is because for A, this statement says nothing about corundum being yellow which means that this doesn’t apply and is incorrect. For B is pretty much the same as A, this statement about corundum doesn’t say anything about it being able to flavor or being flavorful. Lastly for D, the fact that corundum is hard means it would be impractical and probably impossible to use it as pencil lead because, all lead it doing with a pencil is being crushes and ground into the paper as you write.

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.

Explanation:

Hopes this helps!

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.

Evolution refers to the process where complex life forms such as plants and animals originated from simple life forms(prokaryotes) over a long period of time.

Evolution refers to the process where complex life forms originated from simple life forms over a long period of time.

The chart given describes the process of evolution from early life forms.

Earliest life-forms were Prokaryotes which include archeobacteria and eubacteria.

Archeobacteria includes cyanobacteria which generated oxygen that formed ozone which enabled life on land.

Prokaryotes left fossils that were formed 2.5 billion years ago.

Prokaryotes became chloroplasts and mitochondria that originated through endosymbiosis.

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.

Transitional fossil evidence shows intermediate steps in the evolution process. So, the correct option is A.

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.

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).
