What is the main relationship among archosauria, diapsida, and reptilia clases?

Answers

Answer 1

Answer:

Archosauria (the "ruling reptiles") is a major group of diapsids, differentiated from the other diapsids by the presence of single openings in each side of the skull, in front of the eyes (antorbital fenestrae), among other characteristics. This continues the tetrapod trend of the reduction of skull bones by the fusion of multiple bones and the opening of fenestrae in the skull. This helps to lighten the skull, provides more room for muscles and other tissues, and allows more skull flexibility (kinesis) when eating. Other typical archosaurian characteristics include another opening in the lower jaw (the mandibular fenestra), a high narrow skull with a pointed snout, teeth set in sockets (called thecodont tooth implantation), and a modified ankle joint.

Diapsids ("two arches") are a group of amniote tetrapods that developed two holes (temporal fenestra) in each side of their skulls about 300 million years ago during the late Carboniferous period.[1] The diapsids are extremely diverse, and include all crocodilians, lizards, snakes, tuatara, turtles, and birds.[2] Although some diapsids have lost either one hole (lizards), or both holes (snakes and turtles), or have a heavily restructured skull (modern birds), they are still classified as diapsids based on their ancestry. At least 7,925 species of diapsid reptiles[3] exist in environments around the world today (nearly 18,000 when birds are included).

Reptilia, presented as a Class in our classification, includes turtles (Testudines), snakes and lizards (Lepidosauria), crocodiles and their relatives (Crocodilia), and birds (Aves), as well as a number of extinct groups.

What is the difference in the number of chromosomes found in each cell produced in meiosis compared with mitosis?
a-Cells produced during meiosis have half the number of chromosomes as cells produced in mitosis
b- Cells produced during mitosis have half the number of chromosomes as cells produced in meiosis.
c-Cells produced during meiosis have the same number of chromosomes as cells produced in mitosis.

Answers

The cells in our bodies contain 23 pairs of chromosomes - giving us 46 chromosomes in total. Sperm cells and egg cells contain 23 single chromosomes, half the normal number, and are made by a special form of cell division called meiosis. ... Meiosis II divides each chromosome into two copies (much like mitosis).

Air pollution has become an extremely serious problem. Air pollutants affect both plants and animals. Under polluted conditions, plants develop different physiological, morphological and anatomical changes. Pollutants cause damage to cuticular waxes by which then they enter the leaves through stomata. This further leads to injury to plants which can be either acute or chronic. Changes in stomata due to air pollutants which seem to be small can be of great consequence with respect to survival of the plant during stress. These effects can further lead to disturbing the water balance of leaf or whole plant. Respiration also gets affected because of the exposure of plants to air pollutants. The present paper deals with the effect of air pollutants on stomata as well as on respiration leading to affect gaseous exchange.

If a population grows by 3 percent each year, the growth of the population is
A. exponential
B. linear
c. cubic
D. logarithmic

Answers

Answer:

A. (exponential) population

If a population grows by 3 percent each year, the growth of the population is exponential. Hence, option A is correct.

What is exponential growth?

A function called exponential growth depicts an expansion within a population that happens at the same pace across time. If a population doubles or triples in size, you can assume that the data grows exponentially. Exponential decay is the inverse of exponential growth, in which data contracts rather than expands.

Bacteria are one of the best illustrations of exponential growth. Prokaryotic fission is a method of bacterial reproduction that takes around an hour. The population size of 100 bacteria would increase exponentially if we measured it every hour in a certain environment.

The population growth is exponential. Hence, option A is correct.

What can scientists assume about individuals with similar anatomy?
I

Answers

Answer:

Scientists compare the anatomy, embryos, and DNA of living things to understand how they evolved.

Explanation:

Evidence for evolution is provided by homologous structures. These are structures shared by related organisms that were inherited from a common ancestor. Other evidence for evolution is provided by analogous structures

Scientists use anatomy for the study of the evolution of DNA other organs and how they are modified.

Similar anatomy means homologous structure as they provide the information for evolved structure. They provide evolutionary evidence.

What is an analogous structure?

Organisms that have developed alongside special paths may also have analogous systems—that is, anatomical functions which can be superficially just like one another (e.g., the wings of birds and insects). Although such systems serve comparable functions, they have got pretty special evolutionary origins and developmental patterns.

Thus it is clear that scientists assume individuals with similar anatomy for evidence of evolution.

In which system of plant do the tissues xylem and phloem work?

Answers

In vascular system of plant do the tissues xylem and phloem work

Xylem cells are non-living cells that are part of a plant's vascular or conducting tissue. Xylem transports water from the roots upward through the plant, along with nutrients. Xylem is found in vascular bundles, that can be arranged in a circular fashion or a scattered fashion in woody and non-woody parts of plants with wood. The veins found in leaves, stems and roots which are interconnected contain xylem. Phloem, also part of the vascular tissue, conducts nutrients to parts of the plant where needed, particularly sugar produced by photosynthesis. Phloem cells are living and transport sap from the leaves, to roots or to storage areas in a plant such as a bulb. Phloem sap moves from sugar sources to sugar sinks due to turgor pressure gradient.

Both Answer pleasseee, and explain how you got it. please help me pleaseeee The Persistent GardenerIt was Jilly's last day in the green house. Summer was coming to an end and so was the growing season. School would be starting next week and the fall plants were well enough along to allow Mrs. T. to manage the greenhouses herself. As Jilly worked the plants for the last time, she tried to focus on the new school year instead of the details of the greenhouse. It had been a hard, hot summer, but Jilly was not ready for it to be over.Jilly moved down the tables, tucking a stray hair behind her ear with a gloved and already dirty hand. She'd repotted the last of the rosemary plants and mixed a new batch of potting soil already. Mrs. T. now had enough potting soil to last her through September. Jilly looked at a couple of maiden-hair ferns that were beginning to yellow in their small pots. She loved their lacey fronds and had grown concerned over the last few days that they needed repotting or a boost of fertilizer. She had also worried that she would continue to find chores that needed doing, plants that needed help, right up until the minute she left today. She hated unfinished things. She hated details not being tended to.The sun had been above the trees and blasting the greenhouse for a good hour now. Jilly listened for the familiar whirr of the automatic vents opening. When the greenhouse reached a certain temperature, the vents would open automatically. The vents would have a cooling effect for an hour or so, and then no amount of breeze would put a dent in the heat. Mrs. T. often claimed Jilly must be part reptile as she was able to work longer in the greenhouse than anyone else. The heat just didn't bother her. In fact, Jilly often looked forward to the warmth of the greenhouse and feeling the heat seep into her bones. It felt good to her, but she understood others who found it hard to breathe in 100 degree temperatures.Jilly heard the greenhouse door bang, and looked up from her ferns to see Mrs. T. walking down the aisle with a tray of young plants. Mums, Jilly supposed, the flowers everyone wants for fall. She had helped Mrs. T. take cuttings and plant the small stems in new pots. They were doing nicely from the look of things."We will keep these in here for now," said Mrs. T. "They are getting too much rain outside."It had been a rainy couple of days. Jilly knew, as well as anyone, that overwatering could kill potted plants quickly."Do you remember when I overwatered those mint plants?" Jilly asked Mrs. T."I used to think no one could kill a mint plant," Mrs. T. said, laughing."Well I am full of surprises, apparently," Jilly replied. Jilly remembered the sad green plants that just kept looking more and more wilted no matter how much water she gave them. It was a beginner's mistake, and Jilly had been so embarrassed for making it."That you are," replied Mrs. T. "But I know you learned a lesson you won't ever forget.""Of course. Herbs like their roots damp, not flooded," Jilly answered."Well that is not the lesson I was thinking of," Mrs. T. said.Jilly wondered for a minute what the lesson could be. She straightened the rows of geraniums in front of her, picking up one or two to check for aphids under the leaves. It had been a summer full of lessons, some especially hard for a girl who thought she knew a lot about plants. She breathed deeply the warm, humid air. She hated the cooped up feeling of air conditioned air, the feeling of being cut off from the sun. She knew school and the library would offer only these uncomfortable feelings and little time to spend in the sun or with plants. She had come to understand this over the summerher need to be around growing things was huge."I'm not sure, Mrs. T." she said, "I've learned so much this summer. I couldn't possibly say what you are thinking.""You did learn many lessons, Jilly. You knew so much when you started. You've gone farther than any other assistants I've had. I will miss you.""And I will miss you," Jilly replied. "Thank you for the opportunity and the job." Jilly watched Mrs. T. put the tray of mums down on the center row of tables. Wearing her familiar brown apron, Mrs. T. looked just as she had on Jilly's first day."My pleasure, of course, dear," Mrs. T. replied. "My hope for you, as for all my assistants over the years, is that you will learn as much about yourself as you do about growing plants."Recalling her thoughts all morning, about what she enjoyed about her summer job, Jilly realized she knew much more than just how to not drown the mint.Which line from the text best explains the lesson Jilly has learned over the summer? Jilly had been so embarrassed for making it. She straightened the rows of geraniums in front of her. Her need to be around growing things was huge. She loved their lacey fronds.
