Answer:
The first statement is true, while the second statement is false.
Explanation:
Every living organism needs a particular amount of food in order to be able to survive. Each species though has its own different requirements, and there are great variations that occur because of size, lifestyle, is the organism cold-blooded or warm-blooded, etc.
In this case, we have to examples. In the first one, a single mouse needs 4 square meters of grass in order to stay healthy. In order to get the amount of grass needed for fifty mice, we just need to multiply the number of mice by the amount of grass needed for one of them:
50 x 4 = 200
We got 200, meaning that 200 square meters of grass will support a population of 50 mice.
In the other case, a single snake needs 10 mice in order to stay healthy. To get a result how many mice are needed for 10 snakes, again we just need to multiply the number of snakes by the number of mice a single snake needs:
10 x 10 = 100
We got 100, meaning that 10 snakes need 100 mice in order to stay healthy.

-Explain the mechanism of
water
Ascent in plants.
Answer:
Water ascent in plants, also known as transpiration, is the process by which water is transported from the roots to the leaves and other parts of the plant. It occurs through a series of interconnected tubes called xylem vessels, which are located in the stem and branches of the plant.
Explanation:
The mechanism of water ascent in plants involves several factors:
Capillary action: Water moves up the xylem vessels by a process called capillary action, which is the movement of a liquid along the surface of a solid due to the cohesive forces between the liquid and solid.
Cohesion and adhesion: Water molecules are attracted to each other (cohesion) and to the walls of the xylem vessels (adhesion). This causes water to form a continuous column that stretches from the roots to the leaves.
Evaporation: Water is lost from the leaves of the plant through the process of evaporation, which occurs when water molecules escape from the surface of the leaves into the air. This loss of water creates a negative pressure (tension) in the xylem vessels, which helps to pull more water up from the roots.
Root pressure: In some plants, root pressure also plays a role in water ascent. This is the hydrostatic pressure that is generated within the root cells as a result of the active transport of ions and nutrients into the xylem vessels. Root pressure can help to push water up the xylem vessels, especially when the soil is moist and there is a high demand for water by the plant.

Approximately how many molecules of ATP are produced by substrate-level phosphorylation during the complete oxidation of a molecule of glucose (C6H12O6) in aerobic cellular respiration?
Approximately, there are four molecules of ATP are produced by substrate-level phosphorylation during the complete oxidation of a molecule of glucose (C6H12O6) in aerobic cellular respiration.
What is Cellular respiration?Cellular respiration may be defined as a type of biological process that significantly involves the breakdown of food in the cell with the liberation of energy.
In a more simple sense, it is a process of transforming glucose into a form of energy that is known as ATP which is utilized by cells in order to accomplish metabolic and cellular activities.
Two molecules of glyceraldehyde-3-phosphate are formed from one molecule of glucose. Each molecule of G-3-P is responsible for the formation of 2 ATP during the process of substrate-level-phosphorylation.
Hence, a total of four ATPs are produced via the reaction that is known as substrate-level phosphorylation.
Therefore, the number of ATPs that are produced by substrate-level phosphorylation during the complete oxidation of a molecule of glucose is four.

Which type of human cells contain a half set of chromosomes (often written as n)?
Answer:
Gametes are the type of human cells that contain a half set of chromosomes.
Explanation:
In superior organisms that reproduce sexually, such as human beings, the somatic cells are diploid (2n), which means that each cell has a pair of equal chromosomes. The somatic cells are all the body cells excepting for the sexual ones, and they reproduce by the process of mitosis. These cells have a set of chromosomes inherited from the maternal side and another homologous set of chromosomes inherited from the paternal side. Hence, the number of chromosomes in these double sets of the somatic cells are diploid, 2n.
In humans, there are also sexual cells, which are haploid (n). These cells are the gametes, and they reproduce by the process of meiosis. Gametes contain half the number of chromosomes that might be found in the somatic cells. The number of chromosomes in this set is haploid, n.

Farmers use selective breeding to produce bean plants that have the best yields, eliminating breeds that are less profitable.
Pick parents from a mixed population who exhibit these traits. They have interbred. Select the best progeny with the necessary traits to create the following generation. Continue doing this for several generations until all of your progeny posses the desired traits. Plant breeders can utilise self-pollination as a form of inbreeding to generate plants that are increasingly genetically similar and that, after many generations, produce identical offspring. Answer. Crop selection breeding has been used in agriculture for a very long time. Crops that yield more, stand better, or fight pests and disease more successfully may all be produced by simply breeding plants to combine desirable features.

The albedo effect causes a positive feedback loop that causes temperatures in the arctic to rise faster than in other areas. Which is one impact this has on other systems on Earth?
A. This causes more sunlight to be reflected off the surface and into space.
B. This causes organisms in Arctic ecosystems to find more food and shelter.
C. This causes sea levels to rise, potentially destroying coastal habitats.
D. This causes carbon dioxide to be released, which reduces the rate of climate change.
Answer:
The correct answer is C. This causes sea levels to rise, potentially destroying coastal habitats.
Explanation:
The albedo effect is a feedback loop in which the amount of sunlight reflected by the Earth's surface affects the amount of heat absorbed by the Earth's atmosphere. In the Arctic, the loss of ice and snow cover due to warming temperatures leads to a decrease in the surface's albedo, which in turn leads to more heat being absorbed, further warming the region. This warming can cause sea ice to melt, which contributes to rising sea levels. As sea levels rise, coastal habitats can be destroyed, leading to the loss of biodiversity and increased risk of flooding and other coastal hazards.
How do the layers of the atmosphere help to understand better the dynamics of the atmosphere and its relationship to the hydrosphere and lithosphere?
There are various layers that make up the atmosphere, and each has distinct properties and functions. Both weather generation and energy transmission take place in the troposphere, which is closest to the Earth's surface.
The stratosphere shields the Earth from damaging UV radiation along with the ozone layer. Most auroras happen in the mesosphere, where meteors burn up. Modern technology is dependent on the thermosphere, where the majority of the Earth's satellites orbit and where communication signals are sent.
The dynamics of the atmosphere and its interactions with the hydrosphere and lithosphere are better understood thanks to these layers. Foreseeing and minimising environmental problems like climate change and preserving our world, it is essential to understand the significance of each layer.

Neither valine and isoleucine would promote hydrogen bonding with water, because their R groups are nonpolar and thus hydrophobic.1) _______________________________________________________________2) _______________________________________________________________3) _______________________________________________________________4) _______________________________________________________________
Explanation:The changes in the amino acids will affect more the protein structures if the new amino acid has a different R group.
R groups can be neutral, polar, and have different groups such as phenols, Nitrogens, hydroxils, etc. This groups can affect the isoelectric point, changing their conformation when the pH ranges. Moreover, the size of the R group can prevent the original folding of the protein, which can also lead to a missfunctioning, affecting the protein interaction with other molecules.

Explain the ages of crustal rock using evidence of the past and current movements of continental and oceanic crust and the theory of plate tectonics.
The age of crustal rocks can be determined by the help of plate tectonics as the oldest rocks move away and deeper into the ridge.
How to determine age of crustal rocks?
Crustal rocks or Continental crust is the layer of igneous, sedimentary, and metamorphic rocks which are formed by the geological continents and the areas of shallow seabed that are close to their shores which is known as continental shelves.
The surface of continental crust mainly lies above the sea level, its existence allowed the land life to evolve from the marine life. Its existence can also provide broad expanses of shallow water known as epeiric seas and the continental shelves where complex metazoan life could become established during the early Paleozoic period, which is now called as the Cambrian explosion.
By using the magnetic polarity of the sea floor the age of crust rocks can be determined. Very little of the sea floor is older than 150 million years. This is because the oldest sea floor is subducted under other plates and replaces by new surfaces. Thus, the plate tectonics can help in determining the age of crustal rocks.

d. Golgi - Apparatus
a.
Answer:
b. Nucleus
Explanation:
A cell can be defined as the structural, fundamental, biological and functional unit of life. Cells are found in all living organisms because they are the basic unit of life. A unicellular organism refers to a living organism that possess a single-cell while a multicellular organism has many (multiple) cells. Generally, cells have the ability to independently replicate themselves. In a cell, the "workers" that perform various functions or tasks for the survival of the living organism are referred to as organelles. Some examples of cell organelles with their respective functions in all living organisms such as trees, birds, and bacteria include;
1. Cell membrane : is the wall of the cell and typically controls what leaves and enters the cell.
2. Mitochondria : it provides all the energy required in the cell by transforming energy forms.
3. Lysosomes : they are responsible for absorbing materials and breaking the materials taken in by the cells.
4. Chromosomes : they give sets of instructions for the synthesis of products.
5. Ribosomes : they are involved in the build up of proteins.
6. Endoplasmic Reticulum : this is where the ribosomes perform their tasks.
7. Cytoskeleton : they help to maintain and support the shape of the cells.
8. Vesicles : they ensure proteins are properly transported to the right and exact location.
9. Golgi apparatus : it prepares the protein for export by chemically tagging them.
10. Nucleus : it controls all the activities taking place in the cell and the synthesis of proteins.
Hence, the principal site of protein synthesis in a cell is nucleus.
