Answer: 4) white blood cells
Explanation:
The bleeding from a small cut soon stops due to the release of platelets. Hence, option 1 is the correct answer. These are cell fragments of megakaryocytes.
What is a blood clot?When there is a cut, blood comes out of that organ. To prevent blood loss, the body has certain mechanisms. This mechanism is called blood clotting.
In the blood, different cells are present. Red blood cells (RBC), white blood cells (WBC), and megakaryocytes are present in the blood. The red blood cells supply oxygen to the different tissues. It consists of hemoglobin. The white blood cells protect the body from pathogens. Eosinophils, neutrophils, basophils, monocytes, etc. are white blood cells ( WBC)
Megakaryocytes are the cells that form platelets. These platelets are cell fragments of megakaryocytes. When a cut occurs, these platelets come to the site along with other clotting factors such as fibrinogen to form a network-like structure. Due to this network, the blood cells can't come out, and blood loss stops.
Hence, option 1 is the correct answer as platelets prevents the blood loss. Other options are incorrect.

Where do the calories in your food come from?
Answer: Calories are the amount of energy released when your body breaks down (digests and absorbs) food.
Explanation:
The more calories a food has, the more energy it can provide to your body. When you eat more calories than you need, your body stores the extra calories as body fat. Even a fat-free food can have a lot of calories

By leaving crop roots in the ground and stalks on the surface, no-till plowing helps prevent ____________________.
*edit* i now found the answer :) and if you are wondering what it is it soil erosion
i know its says biology but its just regular science on edge 2020
Answer:
Soil erosion.
Explanation:
No-till plowing can be defined as a farming method or technique which typically involves planting crops (seedlings) without tilling the soil rather the farmer would only open a narrow or very shallow trench of sufficient depth and width to cover up the seedlings. Thus, the no-till plowing makes crop residues to be left on the soil and by extension preventing soil erosion through the absorption of water by the crop residues.
Hence, by leaving crop roots in the ground and stalks on the surface, no-till plowing helps prevent soil erosion.
Additionally, the water retention ability of no-till plowing is usually a boon to farmers because it slows down evaporation and serves as a good protection for drought-stricken environments.

Review Questions:
You need to know what biotechnology means to solve the first problem.
Is an umbrella term that covers a broad spectrum of tools and techniques, ranging from fermentation to plant and animal breeding, cell and tissue culture, antibiotic production and genetic engineering. The traits of every organism are encoded in its genetic material which is organized into individual units called genes. Genetic modification is achieved by changing the code or organization of the genetic material of an organism.
1) Recombinant antifreeze proteins that extend the shelf life of frozen dairy products and fruits, fermented whey that is high in acids to preserve cheese and rosmarinic acid produced from rosemary plant cell cultures as an oxidant.
2) Are rich in probiotic bacteria so by consuming fermented foods you are increasing the health of your gut microbiome and digestive system
3) As bread dough is mixed and kneaded, air bubbles are trapped and dispersed throughout the dough. The starches and sugars in the flour, turning them into alcohol and carbon dioxide gas. This gas network of air bubbles, causing the bread to rise.
Critical Thinking Questions:
1) Different ones developed in different regions because the much of there food on there climate. People in cold climates could use the natural resources.
2) Why were beer and wine consumed so commonly? I don't know the answer
3) Bread has been an important staple food product to many cultures. Stone mechanisms were used for smashing and grinding cereals to remove the inedible outer husks.
4) Pasteur completed the first successful test on April 20, 1862, patenting the method we now know as pasteurization, which was soon applied to beer, juice, eggs, and (most famously) milk.
5) Diluted vinegar has been used as a strengthening and energizing tonic. Roman soldiers called this refreshing drink “posca”, and used it regularly as did the Japanese samurai.

Mark me brainliest!!! Much apperciated.
Recombinant antifreeze proteins and fermentation are the methods of food preservation that are examples of biotechnology.
Pasteurization is a process in which pathogenic microorganisms are destroyed or killed in certain foods and beverages by providing specific amount of heat.
The main advantages of Fermentation is that it helps to break down nutrients that is present in food, make it easier to digest than unfermented food substances.
The cheese making process consist of six important steps i.e. acidification, coagulation, separating curds, salting, shaping, and ripening.
Yeast uses the sugars and oxygen that is present in dough in order to produce more yeast cells which releases more carbon dioxide gas. The carbon dioxide cause rise in the dough which gives the bread a light and spongy texture.
Different food preservation methods develop in different regions of the world because the environment as well as different types of pathogens are present which needs different method for its removal.

What factors affect the likelihood a species will migrate from the mainland to an island?
Answer:
The factors that might affect the likelihood a species will migrate from the mainland to an island are the distance to the mainland and the island´s size.
Explanation:
Ecologists MacArthur and Wilson took the term island biogeography theory to refer to the predictions about the number of species that could inhabit an island.
Island biogeography theory establishes that the two factors that affect species richness in natural communities on an island are the distance to the mainland and the island´s size.
At the same time, these factors affect immigration and extinction rates. According to the theory, islands that are closer to the continent have higher possibilities of receiving immigrants than those located farther from the mainland. This is the effect of distance.
The effect of size is reflected in the relation between island size and species diversity. In smaller islands, the probability of extinction is higher than in bigger islands. Bigger islands can have more species than smaller ones.
In the case of two islands of the same size and different distance to the mainland, both of them will have the same extinction rate, but the one closer to the continent will have a higher immigration rate, and so, a higher amount of species. The S value will be higher on the island closer to the continent.

1. A secured object in an orbiting spacecraft remains at rest unless acted upon by
A. an electrical force
B. an external force
C. a magnetic force
D. a frictional force
10 POINTSSSSSS
Answer:
B. an external force
Explanation:
Inertia can be defined as the tendency of an object or a body to continue in its state of motion or remain at rest unless acted upon by an external force.
In physics, Sir Isaac Newton's first law of motion is known as law of inertia and it states that, an object or a physical body in motion will continue in its state of motion at continuous velocity (the same speed and direction) or, if at rest, will remain at rest unless acted upon by an external force.
Hence, a secured object in an orbiting spacecraft remains at rest unless acted upon by an external force.

What is evolution?Evolution is defined as a change in the genetic composition of a population over successive generations. Let’s arrange the theories given by the following in chronological order-
Greek and Rome – The evolutionary theory was proposed for the first time some 2000 years back by Anaximander.
Erasmus Darwin brought his “The law of organic life” in between years 1794-1796.
Lamarck Mallus first presented his theory of Inheritance of Acquired Characteristics in 1801.
Darwin published his work “Origin of species” in 1859.
The Greeks developed, with Miletus, a primitive theory, indicating a possible relationship between man and animals. Erasmus Darwin and Malthus (the first was Charles's grandfather), developed theories that grounded the naturalistic idea. Lamarck brings erroneous concepts, but they are fundamental for Darwin, finally, to develop his Origin of the Species.

1. In your own words, what does it mean for a cell to be
specialized ?
Answer:
For a cell to be specialized it means that, even though the cells are similar, they differ in shape, size, function, and have a different role in our body. Every cell adapts to the function it has in the body.
Explanation:
Differentiation refers to the serial steps that a cell goes through to become mature. As the cell develops, it begins to show its own purpose and role in the human body, a process known as differentiation.
Predict what may happen to the population of pepper moths if they were relocated to a lush, green rainforest ecosystem. How would this impact natural selection and their struggle to survive
Answer:
The correct answer is - The population would decrease.
Explanation:
natural selection is a change of an organism that helps in surviving in an environment change that is unfavorable to it. If a population of pepper moths is relocated a lush, green rainforest ecosystem, it the environment could kill off the peppered moths due to their evolutionary characteristics will make them stand out to predators which decreases their population or kill them due to their diet.
Answer:
The Peppered Moth Population Will Decrease or be Completely Wiped Out.
Explanation:
The change would almost inevitably result in the extinction of peppered moths. They would become extinct, whether they were light or dark in color. Because of their color, they would be unable to blend in with their new lush environment. They would also suffer because their diets are different and contain certain animals than those available in the lush forest.
