Answer:
Gluten contains gliadin and glutenin. Glutenin is elastic and is responsible for the elasticity in doughs and batters. The gliadin fraction is a monomeric protein, the presence of high gliadin makes dough and batter more rigid.
Explanation:
The gluten protein has two fractions of gliadin and glutenin, both of which have culinary values. The more glutenin in wheat used for baking, the more elastic the dough becomes while more gliadin makes dough and batter less elastic.

--> habitat loss and fragmentation
8. wild american ginseng populations have declined as a result of increased demand for the roots.--> overexploitation, or overharvesting
Explanation:
Habitat loss and fragmentation. Refers to the effects of human activities and their expansion in space as populations get bigger and economic activities increase. The expansion of agriculture and cattle industry limits are one of the most important activities responsible for habitat fragmentation. In the last few years, the real estate industry took an important role in habitat fragmentation and alteration. Following this idea of "progress", government and private enterprises alter the natural and pristine environment and open new areas destined for different activities, in most cases contaminating the area. A progressive and continuous change occurs in the natural environment. Following the reduction of habitat, there is a decrease in the size of populations of the affected native species. The species richness decreases, and there is no connection or paths among isolated areas.The introduction of exotic, or non-native, species. Refers to biological invasions. New species that establish in a new area far or out of their original distribution range. These species might be considered exotic or invasive, according to their reproductive rate, population growth, and interaction with native species. Once established, the introduced species expand their distribution from the first invaded spot and overgrows. It is very common for these species to start new populations in the new area, where they have less environmental pressure and better conditions than in their origin area -fewer predators, more resources, better nitches-, and these factors favor their establishment. As they expand, they compete with other species for resources. In the case of plants, these resources are water, place, radiation, exposure, among others. Species are considered to be invasive because of their reproductive rate, population growth, and interaction with native species, which provokes huge damages in the native ecosystems. Biologic invasions are natural processes, that occur in small groups of individuals that can expand to other ecosystems, and the appearing or despairing of barriers promotes their expansion. But these biologic invasions have accelerated by human beings, referring to this as "human-assisted invasions". These are the cases in which men transport species from one place to the other for different uses or purposes. It is very common for these species to scape and start new populations in the new area, where they have less environmental pressure -fewer predators, more resources, better nitches- than in their origin area, which favors their establishment. Overexploitation, or overharvesting. Refers to the unlimited use of resources. People, acting by their own needs or interests, may exceed the harvesting, affecting the resource population and, therefore, other users. Overexploitation might lead to the extinction of the species that are taken in excess and to the decrease in the size of other organism´s populations that also depend on those resources.

If a species has a 2n number of 18, how many autosomes would their SOMATIC cells have?
Answer:
If a species has a number of chromosomes 2n = 18, then its somatic cells have 16 autosomes.
Explanation:
Somatic cells are diploid, that is, they have the complete chromosomal charge, and it is represented as 2n. In organisms with sexual reproduction the chromosomes are divided into autosomes and sex chromosomes, which are 2.
If a species has a number 2n = 18, it means that its somatic cells have 18 chromosomes, of which 16 are autosomes and 2 are sex chromosomes. Autosomes contain the structural and functional characteristics of an individual, while the sex chromosomes determine sex.

Year after year, Xavier raises a vegetable garden in the same plot of soil. He observes that the plants grow less abundantly from one year to the next, and they produce fewer vegetables. Which of these processes could help explain Xavier's observations?
A. the rate at which soil bacteria perform photosynthesis
B. the rate at which soil bacteria perform denitrification
C. the rate at which soil bacteria perform nitrogen fixation
D. the rate at which soil bacteria perform chemosythesis
Answer:
C. The rate at which soil bacteria perform nitrogen fixation
Explanation:
Since Xavier is raising vegetables in the same spot year after year it is reasonable to expect that the plants would deplete the soil of its resources. Since the soil doesn't have enough minerals and not enough time for the bacteria to perform nitrogen fixation the plants don't grow at the same rate and numbers that they used to at the beginning.
Chemicals used in chemotherapy treatments to fight cancer can also harm cells in hair follicles and bone marrow.
What characteristic do these cels most likely share with cancerous cells?
O They form tumors.
O They spread through the blood.
• They divide rapidly.
O They contain a mutation.
A
Answer:
They divide rapidly
Explanation:
Some normal cells such as hair follicles cells, mouth cells, digestive tract cells, and bone marrow cells divide rapidly. In mammalians, hair follicle cells are cells localized in the skin, specifically in the dermal layer of the skin. In this region, epidermal cells that form the root of the hair divide rapidly by interacting with neuropeptides, hormones, and immune cells. On the other hand, the bone marrow is a spongy tissue found in bones that contain stem cells (which also divide rapidly). In consequence, it is well-known that high-dose chemotherapy treatments may damage these types of cells.

How is the space shuttle able to leave earth's surface?
PLEASE TELL ME IS ITS A, B, C, OR D
Answer: A
Explanation:
The shuttle needs to go up in order to get into space, this means they need to create a force greater then gravity because if they didn’t the shuttle wouldn’t be able to accelerate upwards
The space shuttle is able to leave Earth's surface when the space shuttle engine creates an upward force that is greater than downward force of gravity.
The force of gravity pulls every towards the center of the Earth, to overcome this force of gravity the space shuttle will create an upward force that is greater than force of gravity.
The upward force created by the space shuttle engine must overcome the downward force of gravity on the space shuttle.
To overcome the force of gravity, the space shuttle engine speeds upwards with a velocity known as escape velocity.
Thus, we can conclude that the space shuttle is able to leave Earth's surface when the space shuttle engine creates an upward force that is greater than downward force of gravity.

Cellular respiration is the chemical basis of how cells release energy from foods. When you eat an apple, your cells extract energy. The text below explains how cells use cellular respiration to extract energy from an apple. Choose the parts of the sentence that are incorrect.
The apple first enters the digestive tract through the mouth, where digestion begins with chewing. Enzymes begin to break down the apple in the mouth. From the digestive tract, the glucose from the digested apple is absorbed into the bloodstream, where it is brought to cells throughout the body. In the chloroplast, the glucose begins cellular respiration. The molecules react with carbon dioxide to release energy. Oxygen is produced as waste
