Answer:

individuals that develop beneficial traits have a better chance of survival, and are then able to pass on their genes. Eventually, if enough of those genes are passed on, that gene will become more prominent within the population.

Answer: Flowers help purify water and also helps hold the soil in place and prevent erosion.

CREDIT: fed.us

Answer:

The primary purpose of a flower is reproduction. Since the flowers are the reproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.

Answer:

The abiotic characteristics of an ecosystem that affects man includes: Land surface, rainfall and relative humidity.

Explanation:

In the ecosystem, man occupies the terrestrial habitat which is affected by the abiotic factors listed above.

Abiotic (non- living) factors determine the type of biotic (living) community that is found in an ecosystem. These factors include Land surface, rainfall and relative humidity, just to mention a few.

--> LAND SURFACE: This is responsible for the marked variation in the vegetation of a place. For example, a mountain in the tropics may have a rain forest vegetation at it's base and an afroalpine vegetation near its peak. The gradient of the slope affects the growth of organisms. A steep slope encourage fast run - off of water and therefore encourages erosion, which results in shallow and infertile soil. This in turn AFFECT man's farming activities as there would be little to no crop yield.

--> RAINFALL: Water is a very important abiotic factor that affects life. The main source of water to terrestrial habitat is rainfall. When rain falls, a greater percentage of it sinks into the soil while the rest run- off into water bodies. Water is absorbed by root hairs into the plant and used for photosynthesis to produce food. The absence of rainfall in the environment of man could lead to drought which AFFECTS man negatively.

--> RELATIVE HUMIDITY: This is a measure of the amount of moisture in the atmosphere. It's usually high in hot wet regions. It affects the rate at which water evaporates from the body surfaces of organisms. Low relative humidity cause more water (sweat) to evaporate from body surfaces giving the human body a cooling effect. But in high relative humidity, the sweat cannot evaporate leaving the body feeling hot and sticky. This AFFECTS man as the body tries to cool off in a harder way by increasing rate of respiration and depth of blood circulation.

Explanation:

The order goes as;

Biosphere, Ecosystem, Community, Population.

Answer:

Increases

Explanation:

The smaller is the size of the soil, the greater is the interspace distance between the two soil particles. As this distance increases, the water gets more space to travel through thereby increasing the capillary action. Hence, as the size of soil particle reduces, capillarity increases.

Gold is a poor insulator and a good conductor, having a resistivity of 22.4 billionths of an ohm-meter. As with lead, gold is widely used to make electronic contacts. Unlike many other metals, it is very chemically stable and resists the corrosion that degrades other types of electrical connectors.

a) How are aquatic organisms affected by oil spills in the ocean?

Aquatic organisms are affected by oil spilled as it is fatal and toxic to them. It can cause death, habitat degradation, vulnerability to predators and can also lead to the inability to hatch their eggs.

b) Which type of chemical compounds are degraded by microbes used for

clearing oil spills?

The chemical compound degraded by microbes are clearing oil spills are Pseudomonas spp and Alcanivorax borkumensis.

c) Name any two species of microbes which can degrade rubber from

garbage.

These are Vibrio and Ideonella sakaiensis.

d) Why should there be a ban on plastic bags?

There should be a ban on plastic bags as they're difficult to degrade as they are made up of PET.

Answer:

I chose nucleus and the mitochondria

Explanation:

The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.

Answer:

Chlorophyll is any of several related green pigments found in the mesosomes of cyanobacteria and in the chloroplasts of algae and plants. Its name is derived from the Greek words χλωρός, khloros and φύλλον, phyllon. Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light.

Explanation:

Explanation:

Chlorophyll is a green photosynthetic pigment found in plants, algae, and cyanobacteria. Chlorophyll absorbs mostly in the blue and to a lesser extent red portions of the electromagnetic spectrum, hence its intense green color.

S. aureus can develop resistance to methicillin and other -lactam antibiotics by expressing a foreign PBP, PBP2a, which is resistant to methicillin but can perform the functions of the host PBPs.

Staphylococcus aureus is a Gram-positive round-shaped bacterium that pertains to the Bacillota and is a popular member of the body's microbiota, commonly found in the upper respiratory tract and on the skin.

S. aureus can develop resistance to methicillin and other -lactam antibiotics by expressing a foreign PBP, PBP2a, which is resistant to methicillin but can perform the functions of the host PBPs.

Thus, in this way a non-resistant Staphylococcus aureus bacterium can produce a bacterium that is resistant to methicillin.
