Rita planted hydrangeas in her and her grandmother’s home. The same batch of seeds produced blue flowers in her home and pink flowers in her grandmother’s home. This made her conclude that the soil in her grandmother’s garden is alkaline while that in her garden is acidic. This is an example of which type of variation? Explain.

Answer:

As a population grows in an area, a population may experience the effects of increased densities. In a given area, is the maximum population size of the species that the environment can sustain is called the carrying capacity. Carrying capacity is determined by the amount of available resources (food, habitat, water).

Answer: The following assumptions can be made for the green slime.

Explanation:

1. The green slime has many characteristics, which indicates that these are adaptations which were used by the slime to survive. It uses pump to expel out excess water, and in freezing it can shrink itself to maintain its temperature. Thus these characteristics indicates that the green slime is living.

2.  The green slime did not reproduced. This indicates that the slime was not living.  

3. The slime was living because it had characteristics which enable it to survive like other living organisms.

Arrows have come to represent protection and defence from any evil that can come to you. Sustenance – Arrows were used to fight enemies and to hunt food, two important aspects of sustaining life. As a result, an arrow symbolizes maintaining and protecting life.

The arrows in a food chain represent the flow of energy or the transfer of nutrients between different organisms in an ecosystem.

They indicate the direction of energy transfer, showing which organism is being consumed by another. The arrow always points from the organism being consumed (prey) to the organism consuming it (predator).

The primary producers, such as plants or algae, are at the beginning of the food chain and transfer energy to herbivores (primary consumers), which are then consumed by carnivores (secondary consumers) or other higher-level consumers.

The arrows help depict the interconnectedness and energy flow within an ecosystem, illustrating the feeding relationships between organisms.

Answer:

a) Lysosomes because these are filled with digestive enzymes

Explanation:

Answer:

enzymes are protein molecules that act as catalysts, speeding up chemical reactions without themselves getting used up. Each enzyme will only speed up a specific reaction, for example, catalase will speed up the decomposition of hydrogen peroxide into water and oxygen but it will not speed up the breakdown of starch into glucose. Enzymes (e.g. catalase) have active sites with specific shapes that bind to the substrate molecule (e.g. hydrogen peroxide) forming an enzyme-substrate complex. The enzyme-substrate complex then breaks down into the enzyme and product, allowing the enzyme to go on and react with another substrate molecule. Temperature and pH affect enzyme function because they can change the shape of the enzyme’s active site, preventing it from binding to the substrate, just as a broken lock will no longer fit the key. When the shape of an enzyme changes we call this denaturation. Any factor that increases the frequency of collisions between enzymes and substrates (increasing concentration, surface area or temperature) will increase the rate of reaction.

Answer: gene

Explanation: The sequence of bases in a DNA molecule can determine the order of amino acids in a protein molecule. Groups of three bases called triplets represent different amino acids. This is the basis of the genetic code . A sequence of bases (genetic information) on DNA that codes for a protein is called a gene .

Answer: Earth's outer core is deeper within Earth than oceanic crust is.

Explanation:

The Earths outer core is is known as the third layer of the Earth. It is the only layer of the earth which is liquid. and it is majorly constituting of made metals iron and nickel, as well as little constituents of other substances. The Earths outer core is responsible for magnetic field on earth. And it is hotter than the oceanic crust because it is deeper within the earth than the oceanic crust.

The core -outer core and inner core- compose the third and deepest layer of the Earth. The Earth's outer core is hotter than Earth's oceanic crust because the Earth's outer core is deeper within Earth than oceanic crust is.

-------------------

The Earth is composed of three layers known as cortex, mantle, and core.

The outer layer is the cortex, while the core is the inner layer is the core, both of them composed mainly of iron and nickel.

The core can be divided into outer core and inner core.

Near the terrestrial core, the temperature might reach up to 3,500ºC, and solid materials in these areas melt and fuse.

When fusing, materials lose density, becoming lighter and ascending again to the surface, creating the ascending currents.

Differences in temperature and density produce convection currents. Warm  melted materials from the bottom are lighter and can ascend, while cold materials from the surface are denser, so they tend to descend.

Convective currents contribute to the plates' movements over the mantle and keep the surface warm, making life possible.

The heat produced in the core is responsible for the electromagnetic field.

The Earth's outer core is hotter than Earth's oceanic crust because the Earth's outer core is deeper within Earth than oceanic crust is.

Explanation:

The crops will not deplete the soil. The Frog will not lose its toxin because nothing bad comes from that trait. A predator cannot adapt to a toxin in the span of only ten years. The insect population should deplete because the frog should multiply and concur the population of pests since the frog doesn't have any predators.

what is mitochondria?

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP)

what is krebs cycle?

The tricarboxylic acid (TCA) cycle, also known as the Krebs or citric acid cycle, is the main source of energy for cells and an important part of aerobic respiration. The cycle harnesses the available chemical energy of acetyl coenzyme A (acetyl CoA) into the reducing power of nicotinamide adenine dinucleotide (NADH).
