10) explain the process- harvesting,threshing and winnowing?
Answer:
Harvesting is the operation of gathering the useful part or parts of the plant and is carried out at the time when all the nutrients have developed and the edible parts have reached the appropriate degree of maturity.
Threshing or shelling consists of separating the grains, or the shells in the case of groundnuts, from the portion of the plant that holds them.
WINNOWING, the process of separating quality grains from chaff, is a crucial process in the cultivation of paddy. The traditional way of winnowing is making the dried grains fall from a height using shovels and a sieve.
7. Products like "Tums" neutralize stomach acid because Tums is a a. neutral. b. base. c. acid.
Answer:
(B) Products like "Tums" neutralize stomach acid because Tums is a base.
Explanation:
If the product neutralizes an acid, that means it must be a base. Acid + Base = Neutral. If you were to consume an product that is acidic, the stomach will end up being overly acid, which is unsafe for the body. If you were to consume a product that is neutral or "normal", the product would not do as much to neutralize the stomach acid, compared to a more basic pH. Tums has a main ingredient of calcium carbonate, CaCO3, a base. This ingredient helps regulate the pH levels for your stomach so that it does not become too acidic.

reversing the new oral anticoagulants with prothrombin complex concentrates (pccs): what is the evidence?
Newer oral anticoagulants offer quite a few benefits over usual dealers (e.g. warfarin), however, they are nonetheless related to bleeding risk and currently, there is no validated reversal remedy for them. While there is a little guide for the use of sparkling frozen plasma, and restrained information handy on the outcomes of activated recombinant factor VII, preclinical statistics advocate that prothrombin complicated concentrates (PCCs) can also have possible in this setting. PCCs are presently used to successfully reverse warfarin-induced anticoagulation; however, scientific proof for their use with new oral anticoagulants is lacking, with most of the accessible records coming from preclinical animal studies. Furthermore, there appears to be variation in the capability of different PCCs to reverse the coagulopathy brought about by way of the new anticoagulants, and a lack of correlation between the reversal of laboratory check consequences and the reversal of anticoagulant-induced bleeding. Although there have been encouraging results, care must be taken in generalizing findings from animal fashions and nonbleeding human subjects to the state of affairs in bleeding patients. Ultimately, more evidence supporting anticoagulation reversal for new anticoagulants is needed, specifically related to the remedy of bleeding in human patients in a scientific setting. According to the present-day evidence, the use of PCCs can also be considered a sensible strategy in dire scientific situations; however, a consensus has not yet been reached concerning PCC use or dosing, due to lack of scientific data.

Many antelope species, including hartebeest, wildebeest, impala, Thompson's gazelle, and others, live on the African plains and eat many of the same food plants. An increase in the population of any of these species leaves less food for the others. This is an example of what type of relationship?
Answer:
Competition
Explanation:
Competition occurs when many organisms are in search for the same, limiting resource this include food, water,space.
The use of this limited resource by one species decreases availability to the other population especially when there is an increase in population the rate of competition is very high.
Competition reduces the fitness of all the organism and can either be interspecific which is among the same organisms or between different species.

The volume of blood flowing through the skeletal muscles increases greatly during exercise. Give two ways in which the body brings about this increase.
Increase in blood flow to skeletal muscles:
1. Arterial blood pressure changes little during exercise. During exercise, metabolic demands on skeletal muscle increase dramatically. This causes the blood vessels that supply the muscles to dilate, increasing blood flow to the skeletal muscles.
2. The sympathetic nervous system plays an important role in regulating arterial blood pressure and blood flow during exercise, and several key neural mechanisms are involved in altering sympathetic vasomotor outflow.
How does the sympathetic nervous system affect blood flow?
In blood vessels, sympathetic activation narrows arteries and arterioles (resistance vessels), increasing vascular resistance and decreasing distal blood flow. When this occurs throughout the body, vascular resistance increases and arterial pressure rises.
How does the nervous system control blood flow?
Neurological regulation of blood pressure and blood flow depends on cardiovascular centers located in the medulla oblongata. This group of neurons responds to changes in blood pressure, blood oxygen levels, carbon dioxide, and other factors such as pH.

Mitosis, a stage in the cell cycle, is important for what reason?
a. division of the nucleus b. removal of cancer cells
c. synthesis of DNA d. division of cytoplasm
Answer:
A. division of the nucleus
Explanation:
Mitosis is a biological process that the cells of all organisms go through in order to replicate and reproduce. It is part of the cell cycle, which is made up of G1, S, G2, and M (mitosis). In G1, the cell is growing; in S, the DNA of the cell is synthesized, or replicated, so we know choice C is wrong; in G2, the cell is being prepared for mitosis; and finally, in M, the cell actually undergoes cell division.
So, we are looking for an answer choice that involves division: either A or D.
At the end of mitosis, there's an additional process called cytokinesis that actually divides the cytoplasm, so the answer can't be D.
Thus, the answer is A.
irf4 transcription-factor-dependent cd103 cd11b dendritic cells drive mucosal t helper 17 cell differentiation
The discussion of irf4 transcription-factor-dependent cd103 cd11b dendritic cells drive mucosal t helper 17 cell differentiation is given in the below paragraph-
The predominant migratory DC population in the small intestinal lamina propria (SI-LP) is composed of CD103(+)CD11b(+) dendritic cells (DCs), although it is yet unknown what these cells do in vivo. Here, we show that intestine CD103(+)CD11b(+) DC survival required IRF4 to function (IRF4). Mice with a DC loss in Irf4 showed decreased numbers of helper T 17 (Th17) cells that secrete IL-17 in the gastrointestinal tract and failed to support Th17 cell development in draining mesenteric lymph nodes (MLN) after immunization. Both CD103(+)CD11b(+) MLN DCs and DC-derived IL-6 were selectively decreased in the latter. Immunized Il6(-/-) mice were unable to sustain Th17 cell development in MLN in vivo, although CD103(+)CD11b(+) MLN DCs were able to do so in vitro.
Findings collectively point to a critical function for IRF4-dependent, IL-6-producing CD103(+)CD11b(+) DCs in intestinal Th17 cell development.
What is cell differentiation?The transformation of a stem cell from one type to a differentiated one is known as cellular differentiation. Usually, the cell transforms into a more focused kind. Multiple instances of differentiation take place while a multicellular creature develops from a straightforward zygote to a complex system of tissues and cell types.
As adult stem cells divide and produce completely differentiated daughter cells during tissue repair and normal cell turnover, differentiation continues throughout maturity. In response to antigen exposure, some differentiation takes place. Size, shape, membrane potential, metabolic activity, and signal responsiveness of a cell all undergo significant changes during differentiation.

Mitochondria
chloroplasts
Ribosomes
centrioles
Answer:
mitochondria
Explanation:
aerobic is active and energy is produced in the mitochondria so if the mitochondria was damaged it would affect the active transport
In an aerobic cell, active transport is most directly affected by damage to the - Mitochondria as it provides energy for active movement.
Active transport is a movement of particles through the cell membrane against the gradient, or particles too large to move, therefore, they require additional energy to move such substances.
Cellular respiration provides energy for active transport.It takes place in the mitochondria, therefore, cells that perform active transport have many mitochondria.the molecules are moving against their concentration gradient.If mitochondria are damage in a cell there will be no energy formation and as active transport requires energy this process will be affected directly.

Most cells are infinitesimal, and can only be seen under a microscope. In the preceding sentence, what does infinitesimal mean?.
Here, the word infinitesimal means tiny. Most cells can only be visualized under a microscope since they are so tiny.
In general, all cells must be tiny. While not all cells have a sphere-like form, the majority do. A cell's surface area grows as the square of its radius as the radius rises, yet its volume grows as the cube of its radius (much more rapidly).Thus, a cell's surface area to volume ratio drops as it grows in size. If the cell were in the form of a cube, the same reasoning would hold true (below). The plasma membrane won't have enough surface area if the cell enlarges too much to support the rate of diffusion needed to accommodate the larger volume. In other words, a cell gets less effective as it develops. One technique to increase efficiency is to divide, while another is to create organelles with specific functions. These modifications result in the emergence of eukaryotic cells, which are more complex cells.Hence, the correct answer is tiny.

A plate moves south at a rate of 2 cm/year. How many meters south from its original location will the plate be in 4,000 years? 8,000 meters south 4,000 meters south 200 meters south 80 meters southWhich source of evidence did Wegener use to support his theory of continental drift? fossils magnetic fields satellite mapping warm equatorial climates
Answer:
1. 8000 meters
2. Fossils
Explanation:
1. Rate of southern movement of the plate = 2 cm/year.
In 4000 years, the plate will move a distance of 4000 years * 2 cm/year = 8000 meters
Therefore, the plate will move a distance of 8000 meters south in 4000 years.
2. Wegener in supporting his theory of continental drift used fossils, geologic and glacial evidences. He compared the fossils found in different continents and argued that the presence of fossils of certain animal fossils such as the Lystrosaurus which are found in antarctica, India and South Africa indicates that the continents drifted apart as the Lystrosaurus could not have swam across the ocean to get to these different continents. Also, using geologic evidence by comparing rock structures on opposite sides of the Atlantic ocean, he determined that there were similarities between the rock strata of the Karroo system of South africa with the Santa Carina system in Brazil.
