Vegetative propagation is advantageous to farmers? why ?
Answer: The main advantage of vegetative propagation methods is that the new plants contain the genetic material of only one parent, so they are essentially clones of the parent plant.This can also help to maintain consistent quality and taste in products made from plants or crops.

A freshwater fish egg that contains 1% solute lives in a freshwater environment that also contains 1% solute. The freshwater solution can be described as ___________ to the fish egg solution.
Answer:
It is Isotonic to the fish egg solution
Explanation:
It is Isotonic because Isotonic is a solution that has the same solute concentration with another solution I.e the amount of solute in one solution is the same with the other. This slow the free flow of solutes in equal part through the semipermeable membrane from one solution to the other.

What is the reactant of lactic acid fermentation and the product that builds up during exercise?
A) oxygen and lactic acid
B) carbon dioxide and water
C) Glucose and other compounds
D) glucose and lactic acid
Answer:
gotta be D or A but D is more reasonable
D) glucose and lactic acid
Homolactic fermentation also occurs in muscle cells and results in the formation of two molecules of lactic acid from the breakdown of the reactant.Glucose is the simple sugar reactant used in this type of homolactic fermentation, instead of lactose used in the case of bacteria. The reactants are pyruvate, NADH and a proton. This process of energy production is employed by muscle cells when oxygen levels are low, such as during periods of extreme exercise. The lactic acid end product is also one of the factors responsible for muscle soreness after exercise.Thus, reactant is glucose while product is lactic acid for lactic acid fermentation.Therefore, the correct option is D.

According to Darwin’s theory of evolution, in which order do the steps of natural selection happen?
Some members of a population survive and reproduce, their environment or location changes, and favorable traits are passed on to offspring.
A population’s environment or location changes, some members survive and reproduce, and favorable traits are passed on to offspring.
Favorable traits are passed on to offspring in a population, some members survive and reproduce, and the environment or location changes.

Where is carbon located on our planet, and how are these carbon reservoirs different from each other?
Which reservoir of the carbon cycle changes the most and the quickest?
What are the main differences between the carbon flows 300 years ago and today?
Compare the Illustration View and the Chart View of carbon flows into and out of the atmosphere. Why is it helpful to see two different models to explain the same situation?
Over the past 300 years, how did the role of the ocean change with respect to the amount of carbon dioxide in the atmosphere?
What has happened to atmospheric carbon dioxide level and global temperature since the graph in the interactive, which was created in the year 2014?
Explanation:
carbon C,, comes from burning of hydrocarbons ,,which is a component of oxygen hydrogen and carbon ,,,the reservior in which carbon changes is coke,,,carbon flow into the atmosphere is less than the one released and these causes global warming,,due to blockage of the ozone layer leading to rain acid which leads to corrosion of iron,,,,over 300 years the role of ocean has changed,the convectional currents from the see meets carbon due to oxidation,,Co is formed C +O=C0,, ,in 2014,,the rate of global warming increased due to imcrease of release of carbon to the atmosphere,,,

Which fish is bilaterally flattened?
a) chimaera
Say
b) sunfish
c) shark
d) skate
Answer:
B and C
Explanation:
Skates and sunfish are bilaterally flattened
One of the largest bony fish is the ocean sunfish. It is as tall as it is long, with a flattened body, hence options b and d are correct.
What is a bilaterally flattened fish?Any of the approximately 680 species of bony fishes in the pleuronectiform (order Pleuronectiformes) family.
The class Chondrichthyes includes rays, skates, and sharks (Greek, chondro meaning cartilage and ichthosmeaning fish). A cartilage-based skeleton, jaws, paired fins, and paired nostrils are features of Chondrichthyes.
Chimera is linked to sharks, skates, and rays, however, they split off from their relatives the sharks some 400 million years ago. Their upper jaws are connected to their skulls, which sets them apart from sharks.
Therefore, flatfish, are distinguished by their oval-shaped, flattened bodies, like those of flounder, halibut, and turbot, hence options b and d are correct.

Explain incomplete dominance, using snapdragon flowers as an exmaple
Answer:
when a dominant allele, or form of a gene, does not completely mask the effects of a recessive allele, and the organism's resulting physical appearance shows a blending of both allele
Explanation:
Cross-pollination between red snapdragons and white snapdragons result in pink when neither the white or the red alleles are dominant.
Answer:
Sample Answer:
Incomplete dominance is seen in offspring that have a third phenotype not seen in the parents. Snapdragons are an example. The third phenotype results when a snapdragon with the red pigment protein crosses with a snapdragon with a defective gene that produces no pigment, resulting in a white snapdragon. The offspring receive one allele from each parent, resulting in half the amount of pigmentation for red color being expressed. The offspring will be pink snapdragons instead of red or white.
