The essence of meiosis is that a. specialized cell division reduces the chromosome number by half b. gametes are formed that are diploid c. specialized cell division doubles the chromosome number d. gametes are formed that are haploid e. a and d are correct
Answers
Answer:
e. a and d are correct
Explanation:
Meiosis produces 4 daughter cells that are haploid. Haploid means they have half of the chromosomes of the parent cell.
The essence of meiosis is that specialized cell division reduces the chromosome number by half and gametes are formed that are haploid.
Therefore option e is the right answer.
What is meiosis?A single cell splits twice during the meiotic process, resulting in four cells with half the original genetic material. These cells are our sex cells—eggs in females and sperm in males—and they are produced by a specific form of germ cell division in sexually reproducing species. Two rounds of division are necessary, and the end product is four cells with just one copy of each chromosome. The goal is to produce gametes, or sperm and eggs, that contain half of the parent cells' genetic makeup. Meiosis is characterized by DNA replication, two rounds of cell division, and the production of four daughter cells, each of which has half as many chromosomes as the parent cell.To learn more about meiosis, refer

Answer:
Option(A) carbon ,hydrogen,nitrogen,oxygen and sulphur.
Answer:
A.carbon, hydrogen, nitrogen, oxygen, and sulfur
Explanation:
There are five elements that are essential to life. These are Carbon, Hydrogen, Nitrogen, Phosphorous and Sulfur, or CHNOPS for short. We can see that only option A has nitrogen listed. Nitrogen is absorbed by plants through the soil, and by animals through food. It is absolutely essential for many forms of life, especially plants and animals. Many biomolecules contain Nitrogen. Only one choice on this list contains nitrogen and that is option A. Therefore option A is the answer.

Which of the following processes
describes a cell undergoing exocytosis?
A. cell eating
B. diffusion
C. removing water and waste
D. moving molecules along a concentration gradient
Answers
Answer:
C. removing water and waste
Explanation:
Exocytosis occurs when a cell produces substances for export, such as a protein, or when the cell is getting rid of a waste product or a toxin.
Hope this helps
Answer:
[tex]\boxed {\boxed {\sf C. \ Removing \ water \ and \ waste}}[/tex]
Explanation:
We are asked to find a description for a cell undergoing exocytosis. First, let's define the process.
Exocytosis is a type of active transport, so ATP or energy is required to initiate and complete the process.
This process moves substances from the inside of a cell to the outside. Molecules are packaged into vesicles. The vesicle moves to the cell membrane and attaches. The vesicle fuses with the membrane and the molecules inside the vesicle are released.
Essentially, substances are removed from the cell. This is especially useful because it can rid the cell of any waste or excess water. Therefore, the correct answer is choice C.

Why is it important to have a taxonomy or classification of types of collection and how does that help us understand the development of collection strategies, technologies, collection planning, and methods of collection
Answers
Answer:
Classifying and characterizing various types of collection helps us to identify and understand the capabilities and limitations of each type.
Explanation:
By understanding these factors, we are better able to request support, layer collections, and provide a complete collection plan that best addresses our intelligence gaps. Collection strategies ultimately start with these gaps. By understanding all of your available collection capabilities, you can more effectively manage these assets to accomplish the mission. In most cases, you will not be able to have every type of asset or collection medium under the sun, so it becomes even more critical to understand the strengths and weaknesses of those available. Doing so will help a collection manager most effectively utilize the assets available to them to accomplish the collective organizational mission or end state. Without characterization and classification, you cannot fully understand and thus employ the myriad of tools available effectively (Found on a site not mine)
Taxonomy allows us to organize and categorize collections based on their characteristics, which makes it easier to understand the various types of collections that exist and to compare them.
What is taxonomy?All of the world's plants, animals, and microorganisms are included in taxonomy, which is the science of naming, describing, and classifying species.
For a number of reasons, taxonomy, or the classification of collection kinds, is crucial.
Secondly, taxonomy enables us to classify and organize collections based on their traits, which facilitates comprehension of the numerous sorts of collections that exist and allows for simpler comparison.
To ensure that collections are properly managed, preserved, and available for future generations, taxonomy is an essential tool for understanding the development of collection strategies, technologies, planning, and techniques of collecting.
Thus, it is important to have a taxonomy or classification of types of collection.

why can animals move and plants can't?
Answers
Answer:
Plants make their own food from sunlight, water, and carbon dioxide (part of the air). Making food like that is slow, so if they moved around too quickly, they'd starve to death. So, though they do move, it's usually very slowly.
Animals get their food from plants or from other animals. Moving around is a way for them to get more food, not just to use it up. It's also a way to avoid getting eaten.
(Even plants which appear to "eat" food, such as a venus flytrap, are actually only getting vitamins and minerals that way, not extra energy.)

From left to right, the correct order of the minerals from the least hard to the hardest is ⇒ Graphite, Talc, Gypsum, Calcite, Fluorite, Apatite, Magnetite, Pyrithe, Feldespat, Quartz.
Theoretical frame:
Hardness is one of the physical properties of minerals and is a significant one when identifying and recognizing them.
Hardness measures the resistance level of a surface to abrasion. In the specific case of minerals, it measures how minerals resist being scratched or penetrated.
The hardness level is determined by an attempt to scratch or produce a mark on an unmarked surface using sharp elements, such as nails, copper coin, glass, or a steal knife. Notice that these elements also vary in their hardness.
There are different methods used to define hardness, and they are not comparable to each other. The Mohs hardness method defines an ordinary qualitative scale that characterizes the mineral according to their resistance to being scratched by a harder element.
According to the Mohs hardness scale, the level in which the given minerals are placed is as follows,

A scientist examines a cell using a microscope and notes that the cell has a large number of mitochondria and ribosomes. Within the cell are proteins that can contract. Which of the following is the most likely cell type?
Answers
Muscle cells can contract in response to stimuli. Moreover, muscle cells also have a large number of mitochondria and ribosomes for energy requirements and protein synthesis, respectively.
All muscle cells can contract by the interaction of myosin and actin proteins, which form myofibrils, the repeating molecular structure of sarcomeres (the sarcomeres are the functional and structural unit for contraction). The globular heads of myosin bind to actin filaments, forming cross-bridges that cause the muscle cells to contract and expand.Ribosomes are organelles required for protein synthesis. Muscle cells have a lot of proteins, especially actin and myosin myofibrillar proteins, which are responsible for muscle fiber structure.Mitochondria are the energetic centers of the cell. In consequence, thousands of mitochondria can be observed in cells with high energy requirements such as muscle cells, which release a large amount of energy quickly for movement.Mitochondria, using oxygen available within the cells and metabolize food biomolecules to generate ATP (the energy coin of the cells) that power up the cell.Learn more here:
