Low-carbohydrate diets became popular in the late 1990s and were quickly proclaimed to be a fast and easy method of weight loss. The effectiveness and safety of these diets are dependent on the activity and overall health of the individual as well as the total nutritional content of the diet. However, it is true that in some cases, these diets have been effective. What metabolic effects caused by eating a low-carbohydrate diet can be linked directly to a decrease in fatty acid synthesis and an increase in fatty acid oxidation?
a. release of insulin from pancreatic's cells
b. dephosphorylation of AMPK
c. release of glucagon from pancreatic's cells
d. phosphorylation of AMPK
Answer:
c. release of glucagon from pancreatic's cells
d. phosphorylation of AMPK
Explanation:
Low-carbohydrate diets (LCDs) stimulate the secretion of glucagon by a decrease in the blood glucose concentration. Glucagon is a key hormone secreted by pancreatic cells in the same way as insulin but in an opposite way. This hormone (glucagon) prevents glucose accumulation as hepatic glycogen, while insulin helps to the accumulation of glucose in the liver as glycogen, thereby acting to reduce hepatic glucose output. Moreover, the AMP-activated protein kinase (AMPK) is a kinase protein that mediates the phosphorylation and inhibition of acetyl-CoA carboxylase (ACC) in order to reduce the synthesis of malonyl-CoA, a key molecule that regulates myocardial fatty acid oxidation.
like animals plants need continuously reproduce themselves?
Explanation:
Plant reproduction is important to people and animals also because if plants were not continuing to make more of themselves then there would not any plants for people and animals to eat. ... Plants and animals and plants and pollinators are interdependent because they all need each other to survive.
Answer:
like animals plants reproduce by there parent plant from seeds there is three ways plants reproduce from wind, water and animal
animals: animal like monkey eat the fruit of the plant and throw the seed away later it will start growing
wind: when a strong winds occur it will carry plants like dandelions, swan plants away from its parents and when the wind is over it will start growing
water: plants like coconut will fall on the sea and plot away from its parent and after it landed on land it will start growing

Which of the following is a true statement about cellular respiration? (4 points)
Cellular respiration occurs only in plant cells.
Cellular respiration occurs only in animal cells.
Cellular respiration occurs in both plant and animal cells.
Cellular respiration occurs in some plant cells and some animal cells.
Answer:
Cellular respiration occurs in both plant and animal cells.
Explanation:
Cellular respiration occurs in both plant and animal cells, and is an essential process that organisms need to survive.
Cellular respiration is the main way that organisms create energy from the food that they eat.
It occurs in both plant and animal cells because both plants and animals need a way to convert their food into energy forms, such as ATP.
So, the correct answer is that cellular respiration occurs in both plant and animal cells.

Our ability to be conscious of some aspects of our environment while
ignoring others is called:
A. the conscious mind.
B. the two-track mind.
C. selective attention.
O D. preconscious attention.
SUBMIT
Selective attention is our ability to be conscious of some aspects of our environment while ignoring others. Therefore, the correct statement is option C.
What is selective attention?
Selective attention is the ability of our mind to be conscious of some aspects while ignoring others. In selective attention, our mind focuses on a certain aspect of the environment and filters out the rest of the aspects. Selective attention is useful as it allows one to focus only on the useful information and responds to an important stimulus in an environment.
Selective attention can be affected by various factors such as our dedication to particular interests and goals. For example, while we are driving in heavy traffic, we will only focus on the potential hazards and ignores all the other information, such as education, career, etc.
Selective attention involves top-down and bottom-up processing. Top-down processing involves the use of information, such as knowledge, goals, etc. to retain our attention, while bottom-up processing involves the use of sensory information to capture our attention.
Therefore, selective attention is our ability to focus on only certain aspects of the environment.

A biologist studies a population of anteaters living in a large nature reserve. The reserve is surrounded by farms where anteaters are not safe, but the reserve is a perfect place for anteaters: there are few predators and lots of ants. The biologist counts the number of anteaters in the reserve every year for twenty years and finds the size of the population does not change much. Which of the following is the best description of what life in this reserve is probably like for these anteaters?a. The anteaters have little or no difficulties obtaining food and raising offspring. ants. Their tongues are 24 inches long and covered with sticky saliva. Anteaters cannot open b. Adult anteaters compete for food and many young anteaters die. theirmouth, and do not have teeth. Even the stomachs of anteaters are unique: unlike most mammals,c. It is impossible to know without actually observing anteaters in the reserve.
Answer:
Adult anteaters compete for food and many young anteaters die
Explanation:
As there are not many predators and the number of ants is abundant, the population of anteaters should grow on a large scale, however, this is not what happens, since the size of the population is the same for twenty years. This shows that the anteater population itself is regulating the size of the population through internal disputes, where anteaters, due to the high birth rate, end up competing for food and shelter, causing the most young and inexperienced individuals to be killed.

increasing intracellular cAMP leads to smooth muscle relaxation by: Group of answer choices inhibiting IP3 channels, leading to decreased Ca2 in the sarcoplasm and reduced contraction. Increasing the relative activity of MLCP, leading to a decrease in tension. Activating K channels, increasing K leaking out of the cell which hyperpolarizes it and decreases the likelihood of Ca2 entry. Lower levels of MLCK activity, leading to decreased contraction.
Answer:
1. Inhibiting IP3 channels, leading to decreased Ca2 in the sarcoplasm and reduced contraction.
2. Increasing the relative activity of MLCP, leading to a decrease in tension.
3. Activating K channels, increasing K leaking out of the cell which hyperpolarizes it and decreases the likelihood of Ca2 entry.
Explanation
In smooth muscle, cyclic AMP (cAMP) mediates relaxation because cAMP inhibits a specific kinase required for myosin light chain protein (MLCP) phosphorylation, thereby triggering contraction in the smooth muscles. It has been shown that cAMP inhibits 1,4,5-trisphosphate (IP3)-dependent calcium ions (Ca 2+) release by activation of the cGMP-dependent protein kinase (PKG). PKG proteins act to modulate Ca2+ oscillations by stimulating sarcoplasmic Ca2+-ATPase membrane proteins, increasing Ca2+ in the sarcoplasmic reticulum stores and Ca2+ efflux from the cells, and activate voltage-gated potassium (K) channels, thereby leading to membrane hyperpolarization and reducing Ca2+ entry through Ca2+ channels.
Inorganic, crystalline substances found naturally within earth are known as
Answer:
Minerals.
Explanation:
Minerals can be defined as any form of naturally occurring, inorganic solid substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.
Generally, molecules attach on the inside of a mineral to give it shape. Therefore, the molecule of a mineral is a crystal three-dimensional regular structure (arrangement) of chemical particles that are bonded together and determines its shape.
Due to the fact that these molecules are structurally arranged or ordered and are repeated by different symmetrical and translational operations they determine the shape of minerals.
Hence, inorganic, crystalline substances found naturally within earth are known as minerals. Some examples of minerals are iron, copper, aluminum, tin, coal, quartz, feldspar, mica, etc.
What if cellular respiration did not occur
Answer:
cellular respiration is a process that needs oxygen, so when oxygen is not present, they do not happen, but there is glycolysis, which doesn't need oxygen. the process of glycolysis produces 2 ATP and that is what is needed, so to continue glycolysis, the cells go through fermentation.
Explanation:
THE ANSWER IS FERMENTATION!!!!
Answer:
If cellular respiration does not occur, then the level of oxygen present in the cell will get decreased as a result cell can die due to lack of oxygen. This is because cellular respiration provides the energy necessary for cellular activities.

List and explain the characteristics of living things
Answer:
Life process
Movement
Respiration
Sensitivity
Growth
Reproduction
reason:
Life process
Explanation
Earthworms
Movement
All living things move in some way. This may be obvious, such as animals that are able to walk, or less obvious, such as plants that have parts that move to track the movement of the sun.
Earthworms use circular and longitudinal muscles to move through soil or along surfaces.
Respiration
Respiration is a chemical reaction that happens within cells to release energy from food.
The food that earthworms eat supplies their body with energy-rich molecules such as glucose. On entering the cells of their body, these molecules are broken down in a series of steps to release energy to be used by the body, producing carbon dioxide and water as waste products.
Sensitivity
The ability to detect changes in the surrounding environment.
Earthworms have light-sensitive cells scattered in their outer skin. Their skin cells are also sensitive to touch and chemicals.
Growth
All living things grow.
Earthworms hatch from eggs and can grow up to a metre or more in length! Some earthworms are also able to regrow small parts of their body that have been lost or injured.
Reproduction
The ability to reproduce and pass genetic information onto their offspring.
Earthworms have both sperm and eggs within their bodies (they are hermaphrodites) but they cannot self-fertilise and need to mate with another individual. After mating, a cocoon containing the fertilised eggs is deposited in the soil.
Excretion
Getting rid of waste.
Earthworms excrete waste from their anus – the last segment of their body.
Nutrition
The intake and use of nutrients. This occurs in very different ways in different kinds of living things.
Earthworm nutrition comes from a variety of sources, depending on their species. Food types include manure, compost, plant material, fungi, microorganisms and decaying animals. They take in food through their mouths.

Describe how knowing the column (group) number is a "cheat code" for determining the number and types of bonds that an element can form.
Answer and Explanation:
The columns of the periodic table are able to inform the number and type of connection that the elements can make. This is because the number of each column informs the number of electrons in the valence layer of the elements. The amount of electrons in the valence layer is what determines the amount and type of bond that the elements make. The elements in column 1, for example, have 1 electron in the valence layer and therefore will make 1 covalent bond. The elements of columns 15, as another example, have 5 electrons in the valence layer and will need to make 3 ionic or covalent bonds.
To describe how knowing the group number is a cheat code to determine the type of bonds that can be formed, we should first define periodic table
What is periodic tablePeriodic Table is a series of elements in which they are arranged in increasing order of their atomic number from left to right but the table also have groups (column) from up to downwards each group have atoms with same number of electrons in their last shell due to which they all have almost similar properties such as same magnetic properties ,same number of bonds formation, metallic character .
We can say that similarity in properties of members of same group is due to same number of valance electrons . For example group 14 i.e. Carbon Family ,all elements of this group will have 4 valance electrons and will form 4 bonds by sharing of their electrons.

Your mother asked you to put water soluble fertilizer around the roots of her prize winning rose bush. The following week, you noticed the leaves of her rose bush are beginning to turn yellow and wilt. In terms of tonicity and water movement, explain why the rose began to die after the addition of fertilizer. Bonus: What can you do to solve this problem
Answer/Explanation:
The water soluble fertilizer that was added created a hypertonic environment. Concentration of solute is higher around the plant cells thereby leading to the movement of water molecule away from the cells of the rose bush. This is why the rise bush began to wilt as the leaves turn yellow.
Solution:
Give the plants a reasonable amount of water to cause the solution to be isotonic. When the amount of fertilizer and water is relatively balanced, the plants would be able to utilize the fertilizer, feed well and grow well.
