B. They take minerals from soil.
C. They hold the plant in the ground.
D. They make seeds for reproduction.
Answers
Answer:
B.
Explanation:
A cactus stores water in its stem, which allows it to survive and thrive in desert-like environments. Its stem is made up of thick, spongy tissue that helps to absorb and retain large amounts of water. This stored water is then used to keep the cactus hydrated during times of drought and heat.

The three different heat transfer's shown while making of a smore are thermal energy transfer are convection, conduction and radiation.
What is thermal energy?Thermal energy is defined as the internal energy present in the system in a state to thermodynamic equilibrium by virtue of its temperature.
It can also be defined as the energy produced when rise in temperature causes atoms and molecules to move faster and colloid with each other.
Thermal energy are mainly of three types
Convection - When the heat transfer occurs due to actual motion of particles the process is known as convection. Conduction - When the heat transfer occurs due to vibration of subatomic particles in their mean position, the process is known as conduction,Radiation - When heat transfer occurs from one place to another by electromagnetic radiation the process is called as radiation.Thus, the three different heat transfer's shown while making of a smore are thermal energy transfer are convection, conduction and radiation.

The toucan uses its long beak to reach fruits and berries growing on trees in the forest. The energy stored in the fruit and berries is passed on to the toucan when it is eaten. What is the source of energy for the fruits and berries growing on the trees in the tropical forest?
A: Soil
B. Sunlight
C. Heat
D. Water
Answers
Answer:
The type of adaptations of the Toucan and Monstera Plant are physical adaptions. Both of these adapted physical characteristics help these organisms to survive. The difference in their physical adaptation is that in the Toucan, the physical characteristic helps the Toucan consume nutrients. Meanwhile, the adaptation of the Monstera Plant helps prevent harmful things such as mold.
Plants use photosynthesis to convert light into cellular energy, which allows them to make “food” out of the water and nutrients from the soil.

The mass of Betelgeuse is about ___ times the mass of Vega
(This is not multiple choice.)
Answers
Therefore, the mass of Betelgeuse is about 17.634 kg/ 9.5 times the mass of Vega.
Vega is a main-sequence star located in the constellation Lyra. Betelgeuse is a red supergiant star located in the constellation Orion. The mass of Betelgeuse is observed to be about 20 times the mass of the Sun, while the mass of Vega is estimated to be about 2.1 times the mass of the Sun. Therefore, the mass of Betelgeuse is theoretically estimated to be around 9.5 times the mass of Vega.
Experimentally,
The mass of Betelgeuse is 2.188 x10^31 kg
The mass of Vega is 4.246 x 10^30 kg
Hence, the mass of Betelgeuse is about 17.634 kg/ 9.5 times the mass of Vega.

Ionic and covalent bonds help arrange atoms into unique structures for proteins like hemoglobin. Why is this necessary?(1 point)
Answers
Answer:
Ionic bonds can be important to protein structure because they are potent electrostatic attractions. In the hydrophobic interior of proteins, ionic bonds can even approach the strength of covalent bonds
Covalent bonds in amino acids are useful to stabilize the structure of the proteins and their interactions. The ionic bond formed as the atoms in amino acids with opposite charges accompanied strong electrostatic attractions.
What types of bonds are involved in protein structure?Proteins are 3D structures of amino acids that are further made of an amine and a carboxyl group, and are arranged in specific structures in four levels to give rise to the complete protein molecule.
Proteins can be described as the polymers of polypeptides which are structured by arrangements of these chains in a three-dimensional structure. They are folded and are driven by special non-covalent interactions such as peptide bonds, ionic bonds, hydrogen bonds, Van der Waals interaction, and disulfide bridges.
The primary structure is the sequence of amino acids through peptide bonds to form a polypeptide chain. The secondary structure is a sub-structures made by hydrogen bonding between the main chain peptide groups on the polypeptide backbone chain.
Tertiary structure is the 3D arrangement of protein in which α and β helices are folded into a globular structure with the interactions such as hydrogen bonds, salt bridges, disulfide bonds, and tight packing of side chains.

Hey,
So what you would do here is first choose a biome, such as the desert for example, then choose an organism that lives there, or an animal. Then think of what it is like where it lives, is it dry, cold, windy, and so force, just describing the place by its looks and climate. How would this population increase, maybe it would be if there was suddenly more food there for them, or if their ecosystem got better for them to live, then, if they populated more, how would that affect the ecosystem. Maybe some animals would die off more, or some would have to much food. Like what if the fly population suddenly doubled, for example, how would that affect the ecosystem? Now what would happen if that organism was removed? If flies were removed, spiders and a lot of other organisms would not have food, and some organisms would overpopulate because nothing would eat them. That is just an example.

Organism: Jaguar
1. Jaguars live in a range of habitats, including arid scrubland, thick tropical forests, swamps, coastal mangroves, lowland river valleys, grasslands, and mixed-conifer forests. They gravitate toward areas near rivers and streams.
2. Habitat loss, wildlife trafficking, collisions with vehicles, and retaliatory killings by landowners and ranchers who fear that jaguars will kill their livestock have significantly lowered the population numbers of jaguars and threaten them with eventual extinction.
3. If jaguars were to go extinct, the number of these animals would perhaps increase, which might change the current ecosystem, from what it is now, to a new ecosystem that will adjust to the species left.
Biome 2: Desert
Organism: Camel
1. No matter the type, camels are usually found in the desert, prairie or steppe. Though many people think that camels only live in hot climates, they do well in temperature ranges from 20 degrees F (minus 29 degrees.
2. The sudden increase in camel populations could be also related to massive import of live animals. The Arabian Peninsula countries are among the main camel importing countries.
3. A mob of feral camels moves across arid land in the Australian Outback. The animals, introduced to the area in the 1800s, are causing enormous damage to the ecosystem. ... Camels also damage salt lake ecosystems, pollute waterholes, and destabilise desert dunes, which can lead to erosion. Meaning There would be less damage to the ecosystem.
