Answer:
First outgroup → Ray-Finned FishesSecond outgroup → SharksExplanation:
The outgroup is the most distant taxonomic group that shares no traits or characters with the lineages of interest, which compose the ingroup. You can compare the outgroup with the ingroup to determine the evolutive relationship and which characters are primitive or derived.
Even though the outgroup shares a common ancestor with the ingroup, this is placed far away in evolution, making the outgroup to be the taxonomic group less related to the other lineages. The lineages in the ingroup share another common ancestor that is more recent in history.
To select the outgroup, you need to focus on what you are interested in. There might be several outgroups, but you should choose the one that is more related or closer to the ingroups. This selection is important because you need to make comparisons to understand the evolution of specific traits.
In the exposed example, we need to focus on animals that have four limbs. Then, we might assume that the ingroup is composed of Amphibians Crocodiles Dinosaurs. Sharks and Ray-Finned Fish do not have four limbs, so they might be considered outgroups.
From these two outgroups, sharks have a cartilaginous skeleton, while Ray-Finned Fishes have a bony skeleton. This fact makes ray-finned fishes more related to the ingroup than the sharks. So,
First outgroup → Ray-Finned FishesSecond outgroup → SharksA hydrocarbon having chemical formula C4H8, has one double bond. Identify its class.

Which of the following statements helps support the endosymbiotic theory?
Choose 1 answer:
A
All cells contain ribosomes that conduct protein synthesis.
B
Cells contain genetic information in the form of DNA.
If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their
own.
If isolated from a plant cell, a chloroplast can survive and reproduce on its own.
Answer:
C. If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their own.
Explanation:
The endosymbiotic theory proposes that early eukaryotic cells evolved from endosymbiotic interactions among prokaryotic cells. This theory states that mitochondria and chloroplasts were once primitive bacterial cells that were ingested by large anaerobic prokaryotic cells, and then these cells benefited from living and working together. The most important lines of evidence that support this theory are that mitochondria and chloroplasts contain their own genetic material (circular DNA) and their own protein biosynthesis machinery (ribosomes).

Each of the following will result in complement activation EXCEPT Group of answer choices TLR binding to PAMP on the microbe. recognition of lipid-carbohydrate molecules on the surface of the microbe. lectin binding to mannose on the surface of the microbe. Antibody binding to antigen. All of these will result in activation of complement.
Answer:
TLR binding to PAMP on the microbe
Explanation:
The complement system is a group of proteins in the blood that enhance immune responses by complementing the ability of antibodies and phagocytic cells to mediate effector responses (e.g., lysis, activation of inflammation, opsonization, solubilization of immune complexes, etc). Complement can be activated through the recognition of microbes by soluble pattern-recognition molecules (i.e., lectin pathway) or antibodies (i.e., classical pathway). The classical pathway requires the formation of antigen-antibody complexes for its activation (it is a specific immune response). On the other hand, Toll-like Receptors (TLRs) are molecular receptors that recognize viral and bacterial products (i.e., pathogen-associated molecular patterns or PAMPs), which is a key defense mechanism from the innate immune system response.

How does the experiment relate to what you've learned about submersible technology suck as submarines and ROV's?
Answer:
A submersible technology designed to operate the submarines underwater.
Explanation:
We have learned about submersible technology suck as submarines and ROV's is that pumping system is used to remove water from the submarines and ROV's in order to make it lighter. A submersible is designed to push water to the surface. When a pressure switch is turned on, the impeller started to spin drawing water into the pump. The water is then pushed through the pump and brought it to the surface. Due to removal of water, the submarines and ROV's become lighter and they will come to the surface of water.

An anaerobic metabolic pathway that results in the production of two net ATPs per glucose plus two pyruvic acid molecules is glycolysis True False
Answer: True.
Explanation:
Glycolysis is a process that occurs in the cell cytoplasm, in which a 6-carbon glucose molecule is cleaved into two 3-carbon pyruvate molecules. Two molecules of ATP (Adenosine triphosphate, a molecule that acts as a source of energy to perform biological processes.) and two molecules of NADH are also obtained. It is a metabolic pathway responsible for oxidizing glucose in order to obtain energy for the cell. It consists of a series of consecutive enzymatic reactions, and when pyruvate is obtained, it continues to be used in other metabolic pathways in order to continue delivering energy to the organism. Glycolysis takes place both in the absence and presence of oxygen, so it is defined as an anaerobic process. Therefore, the final destination of the products obtained in glycolysis will depend on the conditions of the environment in which it is found, which will determine the metabolic pathway to be followed (i.e., whether oxygen is available or not). In the absence of oxygen, glucose will not be completely oxidized to carbon dioxide and water, generating fermentative products (lactic acid in animals and ethanol in yeast) producing only two net ATP molecules. In the presence of oxygen, the pyruvate obtained during glycolysis enters the Krebs cycle (to produce energy in usable form as ATP or GTP) and then undergoes oxidative phosphorylation (the process by which ATP is formed as a result of electron transfer from NADH or FADH2 to oxygen via a series of electron transporters) producing a net gain of between 36-38 ATP.

Enzymes are _______. Enzymes are _______. made of protein permanently changed by the substrate made of protein, are catalysts, and permanently changed by the substrate made of protein and are catalysts are catalysts
Answer:
enzymes are biological catalysts.
Enzymes are catalysts. Therefore, option (4) is the correct option.
Enzymes are biological catalysts made primarily of proteins that accelerate chemical reactions within living organisms. As catalysts, enzymes lower the activation energy required for a reaction to occur, thus speeding up the rate of the reaction without being consumed or permanently changed themselves. Enzymes achieve this by binding to specific reactant molecules, forming enzyme-substrate complexes, which stabilize the transition state and facilitate the breaking and formation of chemical bonds during the reaction.
Once the reaction is complete, the products are released from the enzyme, and the enzyme remains unchanged, ready to catalyze further reactions. Enzymes play a crucial role in metabolism, cellular signaling, and many other physiological processes, enabling life to function effectively. Therefore, option (4) is the correct option.

Answer/Explanation:
Asexual reproduction is a type of reproduction in which new organisms that are identical are formed form a parent without the fusion of male and female gametes and do not require fertilization. Offspring formed are usually identical genetically, and are referred to as clones of the parent. Usually, only one parent is involved.
1. Two pieces of evidence that shows the potato growing is an asexual method of reproduction are:
i. Only one parent is involved
ii. The new tubers are identical (clones of the parent)
2. Reasons Why the new tubers will be genetically identical:
i. They grow from 1 parent by asexual reproduction
ii. No mixing of male and female gametes, so no exchange of genes takes place

Answer:
a limousine driver dropping off a couple at the school prom
Explanation:
The citric acid cycle, also known as the Krebs cycle, is a metabolic pathway by which carbohydrates, lipids and amino acids can be oxidized to carbon dioxide (CO2) and water (H2O). Coenzyme A (CoA) is a key coenzyme in the citric acid cycle. Coenzyme A acts as a carrier of acyl groups: its acetyl-coenzyme A form delivers the acetyl group to the citric acid cycle in order to be oxidized for energy production. During the citric acid cycle, Coenzyme A delivers the acetyl group to oxaloacetate (a four-carbon molecule), in order to form citrate (a six-carbon molecule that contains three carboxyl groups). Subsequently, citrate is oxidized and decarboxylated to produce a succinyl CoA, 2 CO2, and 2 NADH.
