Answer:
Megaloblasts
Explanation:
Megaloblasts are nucleated red cells that are formed as a result of these three factors.
1. Deficiency in diet of vitamin b12 or folic acid
2. Bad absorption of vitamin b12 or folic acid
3. When there is increase in the demand for vitamin b12 or folic acid.
Megaloblasts are large erythroblasts that comes up in the blood especially in a case of pernicious anaemia.

If infection primarily involves the outermost layers of adult amphibian skin, and if the chytrids use the skin as their sole source of nutrition, then which term best applies to the chytrids
Explanation:
Amphibian populations worldwide have been in decline for many decades now. The spread of the chytrid fungus, Batrachochytrium dendrobatidis, appears to be a major proportion of the decline (Bd). Chytrid sporangia occurs inside infected animals' epidermal cells, animals that subsequently exhibit regions of sloughed skin. They may also belethargic, expressed by the inability to escape and the inability to run. Usually, the infection takes four to five days, at the end of which zoospores are released into the atmosphere from sporangia. Mortality rates of some amphibian populations exceed 100 percent; other species appear to be able to survive the infection.

I hope this helps!
Lungs, diaphragm, larynx, and the trachea are a part of respiratory system.
What is Respiratory system?The network of organs and tissues that aids in breathing is known as the respiratory system. It consists of your blood vessels, lungs, and airways. The respiratory system also includes the muscles that propel your lungs.
Together, these components help the body circulate oxygen and eliminate waste gases like carbon dioxide.
These tests provide your doctor the ability to spot edema or obstructions in your lungs and other respiratory system components. Spirometry is a component of pulmonary function testing, which your doctor may also advise.
Therefore, Lungs, diaphragm, larynx, and the trachea are a part of respiratory system.

How many teaspoons of sugar can dissolve in hot water until it will no longer dissolve after stirring
Answer:
it depends on what sugar you are using
Explanation:
Answer:
Sugar dissolves faster in hot water than it does in cold water because hot water has more energy than cold water. When water is heated, the molecules gain energy and, thus, move faster. As they move faster, they come into contact with the sugar more often, causing it to dissolve faster
Which chemical weathering processes rely primarily on water? Select the two correct answers.
A.dissolution
B.oxidation
D.precipitation

What is the short definition of a plant cell?Plant cells are eukaryotic cells with a genuine nucleus and particular organelles to carry out particular tasks. Plant cells do, however, include several organelles that are unique from those seen in other eukaryotic cells.
Roots, stems, leaves, flowers, and reproductive structures are only a few of the major classes of cells and tissues that are formed when plant cells differentiate from undifferentiated meristematic cells, which are similar to the stem cells of animals. Nucleus part main job is to direct a plant cell's activities by sending instructions to different parts of the cell.

The cell cycle requires energy. Which process supplies this energy so that the cell cycle can take place in all living things
Answer:
Cellular respiration
Explanation:
All living cells strictly require energy in form of ATP to perform their cellular functions. This energy is obtained when food molecules are broken down on their cells in order to release the stored energy in their bonds. This anabolic process is called CELLULAR RESPIRATION.
CELL CYCLE is one of the cellular functions performed by a cell, as every cell needs to undergo division. According to this question, the cell cycle requires energy, which is also supplied via the process of CELLULAR RESPIRATION.

Hey! an organ system is cells all grouped together that have the same function.
Explanation:
In animals, organ systems are all of organs put together. Like the digestive system, muscular system, and nervous system.

Body Systems:
The human body is made of different body systems which help it to perform different processes and manage them. Body systems is made of different Body organs. Two of many organ system are listed below
Digestive System:It is also called Gastrointestinal(GI) System. The GI system starts from mouth and ends at anus. All the organs between and including the mouth and anus comes under GI system.
The GI system intakes food and breaks it down into small and diffusable nutrients and excretes the solid waste products. One of the most important purposes of food is to serve as cellular fuel. Also, carbohydrates, proteins, and fats can all be used by our cells as sources of the energy that they need to stay alive.

Question 9 options:
Vascular plants can only transport watera from one cell to the next cell.
Non-vascular plants can transport water and food in tube like structures called xylem and phloem.
Vascular plants can transport water and food in tube like structures called xylem and phloem.
Non-vascular plants transport water only in their roots.
Answer:C.
Explanation:
The main reason for the size difference between a moss plant and vascular plants is that vascular plants can transport water in a tube structure called xylem and phloem.
Vascular plants contains tissues that makes up their vascular bundles.
The xylem is used to transport water in plants.
Phloem is used to transport food in plants.
Vascular plants differs from non-plants by possessing this structure.
As the grow they add up more these.
this is an evolutionary edge over the non-vascular plants.

Water potential is the tendency of water to move from one place to another. Pumpkin cores were placed in sucrose solutions at 22°C and normal atmospheric pressure. The following data were gathered.
Individual Data for Pumpkin Cores

change in mass
Water 29.15 32.12
0.2 M sucrose 28.45 29.41
0.4 M sucrose 30.92 29.84
0.6 M sucrose 29.25 27.14
0.8 M sucrose 32.09 28.54
1.0 M sucrose 31.67 27.58
a) Complete the above table
b) Graph the percentage change in mass. Label both the x and y axes.
c) Using the graph, determine the molar concentration of the pumpkin cores and explain how it is related to pressure potential.
Answer:
For part A this is how you solve it:
Final mass-Initial mass=x. Then divide x/initial mass to get final percentage
32.12-29.15=2.97. 2.97/29.15= 10.19%
29.41-28.45=0.96. 0.96/28.46= 3.37%
