Compare the plant embryo to the animal embryo. Can you make inferences about the evolutionary relationship between animals and plants based on what the embryos look like?
Answers
Plants show immediate growth, animals do not at first. The cells of plants differ immediately, whereas this is not the case with animals. Animals bend inwards and make a body cavity and plants do not form an inner space.

Read this excerpt from the text "Terrible Twisters."
Formation
Meteorology, or the study of weather, shows that tornadoes form during a thunderstorm. They start from a supercell, which is a column of air that rotates. It looks like a funnel. Wind
going in different directions makes the funnel rotate, or spin. When this spinning funnel touches the ground, it is a tornado. Tornadoes can last for a few seconds or a few hours. They
are many different sizes, but the average tornado is 660 feet wide-the same as the length of two soccer fields. A typical tomado travels 10 to 20 miles per hour (mph), but a tomado
can go up to 300 miles per hour!

Use the information gathered in the Bidirectional Replication of DNA animation to answer the question. Which statement is true of DNA replication? The lagging strand is composed of Okazaki fragments. The leading strand requires multiple primers. DNA synthesis is away from the replication forks. The lagging strand is synthesized continuously. DNA is always synthesized continuously.
Answers
The statement that is true of DNA replication is that the lagging strand is composed of Okazaki fragments.
Let's understand this in detail:
The process by which DNA is replicated is referred to as DNA replication. It occurs in the S phase of the cell cycle and is necessary for cell division to occur.
DNA replication occurs in a bidirectional manner, with two replication forks moving in opposite directions from the origin of replication.
The lagging strand is composed of Okazaki fragments, which are short DNA fragments synthesized in the opposite direction of replication fork movement, which must be stitched together by DNA ligase to complete the replication process.
On the other hand, the leading strand is continuously synthesized in the direction of the replication fork movement, and only requires a single primer to initiate replication. Thus, the statement that is true of DNA replication is that the lagging strand is composed of Okazaki fragments.

distinguish between inducible and repressible operons, and describe one example of each type.
Answers
Inducible and repressible operons are two types of gene regulation systems found in prokaryotic organisms. They control the expression of genes involved in specific metabolic pathways.
Here's a description of each type along with an example:
1- Inducible Operons: - Inducible operons are normally "off" but can be turned "on" in response to certain conditions or inducers. Inducers are molecules that bind to a repressor protein, causing a conformational change that prevents the repressor from binding to the operator region. This allows RNA polymerase to bind to the promoter and initiate transcription.
2- Repressible Operons: - Repressible operons are usually "on" but can be turned "off" in the presence of specific molecules or co-repressors. Co-repressors are molecules that bind to a repressor protein and enable it to bind to the operator, thereby inhibiting transcription. An example of a repressible operon is the trp operon in E. coli.

The amoeba, euglena, and paramecium all have different means of locomotion. How are they different,? Are there any similarities?
Answers
Answer: The amoeba uses pseudopods, which it creates by deforming its body and streaming its cytoplasm. The euglena whips a flagellum to move. The only similarity between the amoeba and euglena in that the euglena can deform its body in an almost earthworm-type motion. This is something like the amoeba's motion and is used to supplement the euglena's flagellum when it wants to move quickly.

what is digestion? Starting from mouth, state the various steps involved in digestion
Answers
Esophagus. Once you begin swallowing, the process becomes automatic. Your brain signals the muscles of the esophagus and peristalsis begins.
Lower esophageal sphincter. When food reaches the end of your esophagus, a ringlike muscle—called the lower esophageal sphincter —relaxes and lets food pass into your stomach. This sphincter usually stays closed to keep what’s in your stomach from flowing back into your esophagus.
Stomach. After food enters your stomach, the stomach muscles mix the food and liquid with digestive juices. The stomach slowly empties its contents, called chyme, into your small intestine.
Small intestine. The muscles of the small intestine mix food with digestive juices from the pancreas, liver, and intestine, and push the mixture forward for further digestion. The walls of the small intestine absorb water and the digested nutrients into your bloodstream. As peristalsis continues, the waste products of the digestive process move into the large intestine.
Large intestine. Waste products from the digestive process include undigested parts of food, fluid, and older cells from the lining of your GI tract. The large intestine absorbs water and changes the waste from liquid into stool. Peristalsis helps move the stool into your rectum.
Rectum. The lower end of your large intestine, the rectum, stores stool until it pushes stool out of your anus during a bowel movement
Answer:
The gastrointestinal system starts in the mouth. In reality, as soon as you eat the first bite, digestion begins here. Chewing splits the meal into sections that are easier to eat, and saliva combines with food to start breaking down the body into a shape that you can consume and use.
Explanation:
The mechanism of digestion can be divided into various phases, such as mouth, stomach, small and large intestine.
A complicated mixture of mechanical and chemical processes are used in digestion. The mechanism includes food intake and push, mechanical or physical digestion, chemical digestion, absorption, and defeat.

if two enzymes from two different organisms catalyze the same reaction, what does a comparison of km values tell you?a. the enzyme with a lower Km has a lower vmaxb. the enzyme with a higher Km has a lower vmaxc. the enzyme with a lower Km has a greater affinity for the substrated. the enzyme with a higher Km has a greater affinity for the substrate
Answers
The correct option is c. the enzymes with a lower Km has a greater affinity for the substrate. Enzymes are biologicals catalysts that speed up chemical reactions in the body.
The substrate is the molecule that an enzyme acts on. Km is a measure of the affinity of an enzyme for its substrate. It is the concentration of substrate at which the reaction rate is half of the maximum reaction rate (Vmax). A lower Km value means that the enzyme can reach half of its maximum reaction rate at a lower substrate concentration, indicating a greater affinity for the substrate. Therefore, if two enzymes catalyze the same reaction, the one with a lower Km value has a greater affinity for the substrate.

Muscle cells and gland cells are effector cells of nervous system.
The various types of cell present in nervous system that actively responds to a stimulus and effects some change is termed as effector cells. Examples of effector cells are- The muscle cells, gland cells or organ cell. Which are capable of responding to a stimulus at the terminal end of an efferent nerve fiber.
Sensory cells are different from effector cells. Sensory cells detect information (like- sounds, light, touch, smell, taste, and temperature) receptors present on their surface. White blood cells are found in circulatory system and are also a part of immune system that provide protection to the body from various infection. Rapid automatic response to a stimulus is called reflex.

The scientific method is a collection of methods for learning new information, correcting old knowledge, and adding new information. Fieldwork is the main method used by cultural anthropologists to gather information for their investigations. This technique usually entails staying with a group of individuals for a considerable amount of time while becoming a respected member of their culture. By gathering and analysing evidence, the scientific method aims to objectively explain natural science. It entails the creation of hypotheses and their use to develop logical defences. Scientists adhere to a set of steps while applying the scientific method.

According to the passage all BUT ONE is a reason to classify viruses as living. That is they A) are capable of protein synthesis. B) contain a nucleic acid, DNA or RNA. C) response to changes in the environment. D) lack mechanisms for metabolic function
Answers
According to the passage, Option D: lack mechanisms for metabolic function is the reason why viruses are considered as living.
A virus is an infectious submicroscopic creature that only reproduces inside of live cells. All kinds of life, including plants, animals, and microbes like bacteria and archaea, are infected by viruses. It cannot be considered living so far as it lacks metabolic function.
The primary criteria used to classify viruses are features of the viral particles themselves, such as the form of the capsid, the kind of nucleic acid (DNA or RNA, double or single stranded), the replication process, the host species they infect, or the disease they cause.

Complete question is:
Scientific researchers discovered agents that behaved like bacteria causing diseases such as rabies and hoof-and-mouth, but were much smaller. At this time it became the general view that viruses were biologically "alive." This changed in 1935 when the tobacco mosaic virus was crystallized and scientists demonstrated that the particles lacked any mechanisms necessary for metabolic function. It was determined that viruses consisted of a nucleic acid, DNA or RNA, surrounded by a protein shell and the scientific view changed: viruses are complex biochemical mechanisms but not alive. When not in contact with a host, the virus remains dormant. During this time there are no biological activities occurring and the virus is nothing more than a static organic particle. In this state viruses can remain for extended periods of time, waiting to come into contact with the appropriate host. When in contact with a host, it becomes active, reacts to its environment and/or host and directs its efforts toward self-replication. The viral goal now is to produce more viruses to attack host cells.
