(b) Using the template of the phylogenetic tree, circle the lineages that share node
Answers
Complete question:
(b) Using the template of the phylogenetic tree, circle the lineages that share node A. You will find the tree in the attached files.
Answer:
The Lineages that share node A are
Chinese river dolphinAmazon river dolphinLa Plata river dolphinDolphinsNarwhalPorpoisesExplanation:
The phylogenetic tree is composed of,
Lineages → These are the taxonomic groups of interest placed in the extremes of the lines called branches. Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor. Root → This is the older common ancestor that all lineages share. The first one in the tree.- Two or more lineages are more related to each other if they share a recent common ancestor. This means that they all diverge from the same node.
- Two or more lineages are less related to each other if they lack a recent common ancestor. This is, the node from which these lineages diverge is placed far away in the tree.
There are also different phylogenetic relationships between lineages.
Apomorphies → Occur when the involved lineages share a trait that they inherited from their most recent common ancestor. This trait evolved for the first time in this ancestor. → This relationship is a homology.Plesiomorphies → occur when the involved lineages share a trait inherited from a common ancestor, but that is older concerning the present traits exhibited by other descendants of the same common ancestor. → This relationship is a homology.Homoplasy → Lineages share a trait that evolved independently in each group. → This relationship is an analogy.Firstly the question is incomplete the image is not attached with it which shows the phylogenetic tree.
The Lineages that percentage node A are
Chinese river dolphin river dolphinLa Plata river dolphinDolphinsNarwhalPorpoisesThe phylogenetic tree consists of:
Lineages → These are the taxonomic companies of hobby located withinside the extremes of the traces referred to as branches.Nodes → These are the ramification points, that are additionally called divergence points. They constitute the area of the maximum latest not unusual place ancestor.Root → This is the older not unusual place ancestor that every one lineages percentage. The first one withinside the tree.- Two or extralineages are extra associated with every difference in the event that the percentage a latest not unusual place ancestor. In this manner, all of them diverge from the equal node.Two or extra lineages are much less associated with every difference in the event that they lack a latest not unusual place, ancestor. This is, the node from which those lineages diverge is located a long way away withinside the tree.
There also are one-of-a-kind phylogenetic relationships among lineages.
• Apomorphies → Occur while the worried lineages percentage a trait that they inherited from their maximum latest not unusual place ancestor. This trait developed for the primary time on this ancestor. → This dating is a homology.
• Plesiomorphies o( while the worried lineages percentage a trait inherited from a not unusual place ancestor, however, this is older regarding the prevailing developments exhibited via way of means of different descendants of the equal not unusual place ancestor. This dating is a homology.
• Homoplasy → Lineages percentage is a trait that developed independently in every group. → This dating is an analogy.

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.

The Infrared wavelength emitted by humans the most because of the temperature of the body. Infrared is an electromagnetic radiation having a frequency lower than visible light. The wavelength of radiation emitted depends on the temperature of the objects. Different objects emit different radiation wavelength due to their internal body temperature. Such type of radiation is known as thermal radiation. Most of the radiation emitted by human body is the infrared, having the wavelength of 12 micron.
Which of the following statements about diffusion is FALSE?
Question 39 options:
smaller surface area of the cell membrane increases the diffusion rate
small molecules travel much faster than larger molecules
a higher concentration gradient increase the diffusion rate
higher temperatures allow for molecules to move quickly across the cell membrane
Answers
Answer:
smaller surface area of the cell membrane increases the diffusion rate
Explanation:
Diffusion is the process by which molecules move from a region of high concentration to a region of low concentration until there is an even distribution. The rate at which diffusion occurs is dependent on certain factors as follows:
- Temperature: An increase in temperature increases the rate of diffusion because there is an increase in the kinetic energy of the molecules in response to temperature.
- Surface area of the cell: A cell with large surface area undergoes diffusion at a higher rate than a cell with small surface area.
- Concentration gradient: The difference in concentration of the molecule on each side of the membrane is the CONCENTRATION GRADIENT, which when increased also increases the rate of diffusion.
- Size of molecules: small molecules tend to travel faster than larger ones, hence, they diffuse faster.

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?
Answers
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).
what two gases easily diffuse through the phospholipid bilayer
Answers
Answer:
Consider substances that can easily diffuse through the lipid bilayer of the cell membrane, such as the gases oxygen (O2) and CO2. O2 generally diffuses into cells because it is more concentrated outside of them, and CO2 typically diffuses out of cells because it is more concentrated inside of them.

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.

Answer:
lol
Explanation:
Some cells release active signaling proteins when membrane-bound precursor proteins are cleaved by proteolytic enzymes. The signaling proteins can then bind to receptors on the surface of a target cell, thereby activating an intracellular signaling pathway and eliciting a response from the target cell. This mechanism of activating receptor-binding signaling proteins has been observed in a variety of organisms from bacteria to humans. Many of the enzymes responsible for proteolysis of membrane-bound precursor proteins have been isolated and characterized.
Required:
What questions would be most appropriate to investigate whether the proteolytic enzymes are evolutionarily conserved among species?
Answers
Answer:
Following questions would be most appropriate to investigate whether the proteolytic enzymes are evolutionarily conserved among species:
Are the genes encoding the proteolytic enzymes expressed in the same cell types in all species? Once the precursor proteins of different species are cleaved, do the active signaling proteins bind to the same receptors on different target cells? If a proteolytic enzyme from one species is incubated with a precursor protein from another species, does correct cleavage occur? Are the proteolytic enzymes synthesized in the rough endoplasmic reticulum of all species?
