which of these sources add water to lakes
Answer:
what are the sources bff
Explanation:
Answer:
Rain runoff, groundwater, melting snow.
Explanation:
Rain flows through various paths and goes into lakes, carrying various types of small leaves or soil particles along with it into the lake.
Groundwater can also form lakes and is the source of freshwater.
The melting snow is also the source of freshwater that flows and reaches the nearby ponds or lakes present in the nearby areas.
Sewage discharge and fertilizer runoff is detrimental to coral growth because it increases the ________. water temperature that kills zooxanthellae water temperature that results in coral bleaching amount of toxic synthetic chemicals which stimulate excessive bacterial growth salinity of the water that results in coral bleaching amount of inorganic nutrients in the water that stimulates excessive algal growth
Answer:
The correct answer is - amount of inorganic nutrients in the water that stimulates excessive algal growth.
Explanation:
Fertilizers, sewage discharge and industrial runoff has various chemicls enrich with the inorganic compound and elements that causes eutrophication of the the water body.
Eutrophication causes increase in the number of phytoplanktons and algal growth that is stimulates by the amount of inorganic nutrients.
Thus, the correct answer is - amount of inorganic nutrients that leads to excess growth of algae.

Identify the error in the following statement: “Photosynthesis is a chemical reaction that takes place in the chloroplasts of green plant cells, where light energy is used to convert glucose and water into carbon dioxide and oxygen.”
A. “glucose” and “carbon dioxide” should be switched
B. No errors
C. “water” and “oxygen” should be switched
D. “chloroplasts” should be “mitochondria”
Photosynthesis is a chemical reaction that takes place in the chloroplasts of green plant cells, where light energy is used to convert carbon dioxide and water into glucose and oxygen. Option A is the right answer.
What is photosynthesis?Photosynthesis is the process by which green plants prepare their own nutrients with the help of sunlight, water, and carbon dioxide.
Photosynthesis helps plants to prepare their own food, these plans are called autographs.Photosynthesis takes place inside the protoplast.This process takes place in some other organisms other than green plants.Chlorophyll is the green pigment that is required for this process to take place.The end products that are formed in the process of photosynthesis are glucose and water.Hence Option A is the right answer.

Elephants are not the most common species in African grasslands. The grasslands contain scattered woody plants, but they are kept in check by the uprooting activities of elephants. Take away the elephants and the grasslands convert to forests or to shrublands. The newly growing forests support fewer species than the previous grassland. Given this, elephants can be defined as what type of species in this community
Answer:
The elephants are the keystone species in this ecosystem.
Explanation:
The elephants' job is to knock down trees from time to time to get food from tall stock. This prevents the trees from overpopulating and allows shrub lands to stay in place. This is important as herbivores can continue to graze in large herds and carnivores can continue using the same hunting strategies with little to no push backs by trees.
This makes to elephants a keystone species as without them, the foundation species will decrease in population and create a whole different ecosystem with the trees as the new foundation species.
For some parents, their offspring have larger beak depths; for others it's smaller. How does the concept of variation of traits help to explain this?
Answer:
beak depth is a complex (quantitative) trait
Explanation:
Additive effects refer to the resulting effects of two or more genes acting together. Beak depth is a quantitative trait whose variation is determined by the additive effects of many genes acting together and the environment. In quantitative traits, variation is continuous and produces a range of phenotypes. In consequence, in this case, some offspring will have a larger average beak depth compared to their parents, whereas others will have a smaller average beak depth compared to their parents. It is due to the combination of alleles or 'additive effects' inherited from different parents, and the interaction between these genes and the environment. Heritability refers to the proportion of quantitative trait variation due to additive genetic factors: a higher heritability is due to the predominance of additive genetic effects and less influenced by environmental effects.

what are mendelian genetic used for
Answer:
Mendel first observed the different patterns of gene segregation for selected traits in garden peas and was able to determine probabilities of recurrence of a trait for subsequent generations and analyses of large families with many affected individuals can be used to determine whether a disease-associated gene is located on an autosome or on a sex chromosome, and whether the related disease phenotype is dominant or recessive.

Acute disease come rapidly and are accompanied by symptoms that require short term care and therefore get better once treated.
chronic disease are slower to develop and may progress over time hence have many warning signs or no signs .
define and describe osmosis
Answer:
Movement of a solvent (such as water) into a solution with a higher solvent concentration by means of a semi-permeable membrane (as from a live cell), which tends to equal solute concentrations in the membrane on both sides.
Explanation:
Osmosis, the spontaneous transition, distribution, or diffusion of water and other solvents over a semipermeable membrane. In 1877, a German physiologist, Wilhelm Pfeffer, researched the process, which is important in biology.
Osmosis is the passage of water down its concentration gradient, across a semi-permeable membrane. An everyday example is a plastic wrap in your kitchen: it allows air and water vapor to move across it, but no water or food. The membranes of cells are semi-permeable, too.

Though plants, fungi, and prokaryotes all have cell walls, we place them in different taxa. Which of these observations comes closest to explaining the basis for placing these organisms in different taxa, well before relevant data from molecular systematics became available?
Answer:
Due to other differences.
Explanation:
The plants, fungi, and prokaryotes all have cell walls, we place them in different taxa because of the other differences such as mobility, mode of nutrition etc. Plants and fungi are not mobile means can not move from one place to another whereas prokaryotes are mobile. Fungi and prokaryotes are heterotrophs means that feed on other organism whereas plants are autotrophs means make their own food. There is also difference in their cell wall i.e. the cell of plants is composed of cellulose, the cell wall of prokaryotes especially bacteria is composed of peptidoglycans and the cell wall of fungi is composed of chitin.
